    The present invention relates to the field of communications and in particular to a processing method and a processing system for delivering multi-carriers. Fundamentals of the Invention
    Fig. 1 shows a schematic structural diagram of an Evolved Universal Mobile Telecommunication System Radio Access Network (E-UTRAN) of the Long Term Evolution (LTE) system, according to the state of the art. As shown in fig. 1, LTE consists of E-UTRAN and an Advanced Packet Core (EPC), with the network having a flat structure. The E-UTRAN is connected to the EPC via an S1 interface, where the E-UTRAN consists of a plurality of Advanced B Nodes (eNB), which are connected to each other via the X2 Interface; and the EPC consists of a Mobility Management Entity (MME) and a Serving Gateway Entity (S-GW).
    In LTE network system, when the user equipment (UE) moves in the network coverage area, such movement can cause variation of the serving cell of the UE. In order to maintain continuity of service for the UE, the network is requested to assist the UE to deliver between individual cells, where an initiating side of the delivery is called the source side, while the destination side of the delivery is called the target side.
    To satisfy the demand for higher bandwidth, LTE-Advanced (LTE-A) proposes a method of carrier aggregation to achieve higher bandwidth, in which a UE can operate at a plurality of continuous or discontinuous carriers (each carrier is called of a Component Carrier, ie CC). Among the CCs, there is a Primary Component Carrier (PCC), while the others are Secondary Component Carriers (SCC). For each CC, there is a serving cell providing service to the UE, where the serving cell in the PCC is called a Primary Cell (Pcell), while the serving cell in the SCC is called a Secondary Cell (Scell). LTE-A radio resources can be assigned to more than one carrier, that is, to at least one Pcell and zero to multiple Scells.
    In a prior art LTE-A multi-carrier system, when a plurality of cells can be treated as the target cell, a source base station cannot determine which cell should be used as the delivery target cell, therefore, delivery cannot be achieved. Invention Summary

Detailed Description of Modalities
    The present invention will be described in detail with reference to the figures in combination with the following embodiments. It should be noted that the modalities and the characteristics and characteristics of the modalities can be combined with each other if no conflict results.
    The delivery process of an LTE-A multi-carrier system mainly comprises: a source base station, a target base station and a user equipment. In the handover process, during X2 handover, base stations communicate with each other via an X2 interface directly; during the delivery of S1, the base stations communicate with each other via an MME.
    Embodiment 1 A processing method for delivering multi-carriers is provided in accordance with an embodiment of the present invention. Fig. 2 is a flowchart of a first processing method for delivering multi-carriers in accordance with the embodiment of the present invention. As shown in fig. 2, the method comprises the following steps.
    In Phase S202, a source base station determines, according to a bearer-carrier-aggregation relationship obtained between cells in an adjacent base station, a target Primary Cell (Pcell) and target Secondary Cell (Scell)(s) and notifies a station target base to which the target Pcell and target Scell(s) belong.
    In Step S204, the target base station also configures the target Pcell, the target Scell(s) and a corresponding handover command, and sends the handover command to the source base station.
    Phase S206, the source base station sends the handover command to a user equipment which, according to the handover command, carries out a handover process.
    In the prior art, a handover cannot be achieved in the LTE-A multi-carrier system because the source base station cannot determine which cell should be used as the delivery target cell. In this modality, the source base station determines the target Pcell and the target Scell(s) and achieves the delivery process. Specifically, the source base station can learn which cells in a target base station can be transported aggregated, such as adjacent cell NCelH of cell CC1, adjacent cell NCell2 of cell CC2 and adjacent cell NCell3 of cell CC3; and the source base station can learn that NCelH, NCell2 and NCell3 belong to the same base station through configuration or automatic adjacent management function. Then, the source base station determines according to the obtained carrier-carrier-aggregation relationship, whether two or more cells from NCelH, NCell2 and NCell3 can be aggregated per carrier. In this way, the source base station can learn loading and resource information from a plurality of cells in a target base station when making the delivery decision. Therefore, the source base station can select multiple cells in a target base station as target cells of UE handover, thus achieving handover in a multi-carrier system.
    Preferably, in phase S202, the source base station obtains the support-carrier-aggregation relationship through Operation, Administration and Maintenance (OAM) configurations or an information interaction via Interface X2. With this preferred mode, the source base station can obtain the carrier-carrier-aggregation relationship by a pre-configuration mode or an auto-configuration mode.
    Preferably, in phase S206, the user equipment performs a random access according to the target Pcell indicated in the delivery command. Consequently, the user equipment transmits data with the target Pcell and the target Scell(s).
    Additionally, in step S202, the source base station notifies the target base station via a delivery request message during the delivery of X2; in step S204, the target base station directly sends the handover command to the source base station during the handover of X2. With this preferred modality, the delivery of X2 in a multi-carrier system can be achieved.
    Additionally, in step S202, the source base station notifies the target base station via a delivery request message via a Mobility Management Entity during the delivery of S1; in phase S204, the target base station sends the handover command to the source base station via the Mobility Management Entity during handover of S1. With this preferred modality, the delivery of S1 in a multi-carrier system is achieved.
    The process of implementing this modality will be described in detail below.
    Suppose an LTE-A UE performs aggregation of three transporters of CC1, CC2 and CC3 in the cells of a source base station S-eNB, where cell CelH-1 in CC1 is a primary cell, cell Cell2-1 in CC2 is a secondary cell, and the Cell3-1 cell in CC3 is a secondary cell. The S-eNB has an adjacent base station T-eNB that supports four frequencies including CC1, CC2, CC3 and CC4, where CC1 has a CellH-2 cell over it, CC2 has a Cell2- cell. 2 over it, CC3 has a Cell3-2 cell over it and CC4 has a Cell4-2 cell over it. And CelH-1, Cell2-1, Cell3-1 are adjacent cells corresponding to CelH-2, to
    Cell2-2, Cell3-2 and Cell4-2, ie, delivery can be performed between any cells in the two base stations on a single carrier, where the CelH-2, Cell2-2 and Cell4-2 in the T-eNB they can carry out transporter aggregation, and Cell3-2 is a single transporter cell.
    The source base station obtains the support-carrier-aggregation relationship between cells in adjacent base stations through OAM configurations or information interaction via Interface X2. The delivery phases include that: the source base station determines a target Pcell and a target Scell(s), and notifies the target base station during the delivery of S1 or X2; the target base station prepares the handover in accordance with the Pcell and the Scell(s) determined by the source base station, and sets up a corresponding handover command; the source base station sends the handover command to a UE that performs a random access according to the target Pcell indicated in the handover command, and then performs handover.
    A premise of the present embodiment is that the source base station is asked to learn the available aggregate relationship between adjacent cells in the adjacent base station prior to handover. In an LTE system, a source base station may obtain adjacent cells from adjacent base stations by a pre-configuration mode (such as OAM mode) or an auto-configuration mode (such as X2 Information). Therefore, in the LTE-A system, the aggregation relationship can be configured by a pre-configuration mode or an auto-configuration mode.
    Taking autoconfiguration mode as an example, according to the autoconfiguration process in the prior art, adjacent relationship can be obtained through an initial X2 installation process, or an X2 update process. The neighbor information element is included in an X2 install request message, an X2 install response message, and an eNB configuration update message, which also includes an E-UTRA Cell Global ID (E-CGI ), a Physical Cell Identification (PCI) and an E-UTRA Absolute Radio Frequency Channel Number (EARFCN) of an adjacent cell. Through the neighbor information element, two eNBs can learn each other's cell configuration and establish each other as their own adjacent cell. On this basis, eNBs can update aggregation information on neighboring information elements, place cells that can be aggregated together into a group, and notify other base stations of such group information. In the present example, when X2 of the S-eNB and T-eNB initially installs, the S-eNB sends an installation request from X2 to the T-eNB, where neighboring information thereof includes information from Cell1-1, of Cell2-1 and Cell3-1, and it is indicated in the aggregation information thereof that CellH-1, Cell2-1 and Cell3-1 can be mutually aggregated. After receiving the installation request from X2, the T-eNB saves it and sends an installation response from X2 to the S-eNB, where neighboring information of it includes information from CelH-2, Cell2-2, Cell3 -2 and Cell4-2, and it is indicated in the aggregation information of the same that CellH-2, Cell2-2, Cell4-2 can be mutually aggregated, while Cell3-2 cannot be aggregated with other cells. When the aggregation relationship changes, the changer notifies the change to the adjacent base station via an update eNB configuration message.
    After the S-eNB learns the aggregation information from the T-eNB, if the S-eNB reports that an adjacent cell Cell2-2 is better than the current Pcell, ie, the CelH-1, then the S-eNB will determine perform handover when a UE triggers handover, just as the UE triggers a measurement reporting event A3. In such an event, if a delivery of X2 is performed, it is specified that in a delivery request message (Delivery Request) that Cell ID of the target cell is Cell2-2. In LTE-A, the T-eNB interprets Target Cell ID as the one that the S-eNB requests the target Pcell to be Cell2-2, and carries a KeNB* generated by parameters provided by Cell2-2 and a Next Hop Chaining Count (NCC) corresponding to KeNB* in an AS Security Information. The S-eNB will also specify that the target Scell(s) is CelH-2 and Cell4-2 in the Delivery Preparation Information carried in an RRC context in the AS Security Information. Generally, the S-eNB also selects the target Scell(s) according to the UE measurement report to ensure normal usage after delivery. If an S1 delivery is performed, the S-eNB fills the T-eNB's eNB ID into the Target ID in a requested delivery message and transports a Transparent Container from Source eNB to Target eNB in a Transparent Container from Source to Target, where the Target Cell ID and the RRC container thereof have the same contents of the Target Cell ID and the RRC context in a Delivery Request of an X2 delivery mentioned above. The MME will forward the “Transparent Container from Source eNB to Target eNB” to the T-eNB via the Delivery Request according to the Target ID.
    Upon receiving the delivery settings from the S-eNB via the X2 Delivery Request or the S1 Delivery Request, the T-eNB specifies Cell2-2 as the target Pcell and two cells, Cell 1-2 and Cell4 -2 as the target Scells. The T-eNB prepares resources according to these carrier configurations, and configures a Uu interface handover command accordingly, where in the handover command, the UE handover is specified, and it is specified that Cell2-2 is the Pcell target, and CelH-2 and Cell4-2 are the target Scells, and the related configuration information of the carriers and resource reservation at the site are also specified. If the delivery of X2 is performed, the T-eNB conveys the delivery command via the information element “Transparent Container from Target eNB to Source ENB” in the Delivery Request Confirmation. If the delivery of S1 is performed, the T-eNB sends the Delivery Request Confirmation to the MME via a Transparent Container from Target to Source which carries the above information element “Transparent Container from Target eNB to Source ENB”, and the MME forwards the Delivery Request Confirmation to the S-eNB via the delivery command. If a reception failure occurs at the T-eNB, for example, the local resource of Pcell or Scell is limited, it needs to respond to a failure response message. In the case of X2 delivery, the Delivery Preparation Failure is responded to for the S-eNB. In the case of the delivery of S1, the Delivery Failure is responded to, and after receiving the response, the MME forwards the Delivery Preparation Failure to the S-eNB. In order to avoid delivery failure resulting from Scell's failure to receive, in order to influence the success of the final delivery rate (when a carrier's failure to receive rate is p, and N carriers are delivered synchronously, the rate of delivery failure is N*p), the T-eNB can respond a partial success response when the Pcell successfully receives while the Scells receive unsuccessfully. For example, in the present modality, when Cell2-2 successfully receives, CelH-2 successfully receives, and Cell4-2 receives unsuccessfully, T-eNB sets up a delivery command according to Cell2-2 as Pcell and CelH-2 as Scell, and reserves related resources, and responds to a delivery command to the S-eNB according to the above process. Additionally, the partial failure information can be indicated in the corresponding message, for example, in the present modality, it is indicated that Cell4-2 receives without success, which is not configured in the Delivery Command.
    The S-eNB receives the handover command sent from the T-eNB (or forwarded by the MME), and sends it to a UE via an air interface RRC Connection Reset command. The UE, according to the Cell2-2 target Pcell specified in the message, initiates a random access on a Cell2-2. Upon success, the UE sends a “Complete RRC Connection Reset”. The T-eNB, after receiving said message, releases resources from the S-eNB, which is the same as the subsequent LTE flow.
    According to an embodiment of the present invention, a processing system for delivering multi-carriers is provided. Fig. 3 is a structural block diagram of a first processing system for delivering multi-carriers in accordance with an embodiment of the present invention. As shown in fig. 3, the system comprises a source base station 2, a target base station 4 and a user equipment 6, wherein: the source base station 2 comprises: a first determination module 24, which is adapted to, according to a relationship support-carrier-aggregation obtained, determine a Primary Cell (Pcell) target and Secondary Cell (Scell)(s) target; a first notification module 26, which is connected to the first determination module 24 and adapted to notify the determined result determined by the first determination module 24 to the target base station to which the target Pcell and the target Scell(s) belong; a first receiving module 28, which is adapted to receive a handover command from a target base station; and a first forwarding module 20, which is connected to the first receiving module 28 and adapted to forward the delivery command to the user equipment; the target base station 4 comprises: a fourth receiving module 40, which is connected to the first reporting module 26 and adapted to receive the determined result from the first reporting module 26; a first configuration module 42, which is connected to the fourth receive module 40 and adapted to configure the target Pcell, the target Scell(s) and a corresponding delivery command; and a first sending module 44, which is connected to the first configuration module 42 and the first receiving module 28, and adapted to send the handover command to the source base station; and the user equipment 6 comprises: a fifth receiving module 60, which is connected to the first forwarding module 20 and adapted to receive the delivery command from the first forwarding module 20; and a first delivery module 62, which is connected to the fifth receiving module 60 and adapted to carry out a delivery process in accordance with the delivery command.
    In the prior art, delivery cannot be achieved in an LTE-A multi-carrier system because the source base station cannot determine which cell should be used as the delivery target cell. With this modality, the source base station determines the target Pcell and the target Scell(s) and achieves the delivery process, the source base station can learn which cells in a target base station can be aggregated per carrier, and learn exactly the information loading and resources from a plurality of cells at the target base station when making the delivery decision. Therefore, the source base station can specify multiple cells in a target base station as the target cells of a UE handover, thus achieving handover in a multi-carrier system.
    Preferably, the first delivery module 62 performs a random access according to the target Pcell indicated in the delivery command; consequently, the user equipment carries out data transmission with the target Pcell and the target Scell(s).
    Preferably, a first acquisition module 22 obtains the carrier-carrier-aggregation relationship through OAM configurations or an information interaction with an X2 interface. With the preferred mode, the source base station can obtain the carrier-carrier-aggregation relationship by a pre-configuration mode or an auto-configuration mode.
    Additionally, the first notification module 26 notifies the target base station via a delivery request message during the delivery of X2; the first sending module 44 directly sends the handover command to the source base station during X2 handover. With the preferred mode, a multi-carrier system X2 delivery process can be achieved.
    Additionally, the first notification module 26 notifies the target base station via a delivery request message via a Mobility Management Entity during the delivery of S1; the first sending module 44 sends the handover command to the source base station via the Mobility Management Entity during handover of S1. With the preferred mode, a multi-carrier system S1 delivery process can be achieved.
    Embodiment 2 According to an embodiment of the present invention, a processing method for delivering multi-carriers is provided. Fig. 4 is a flowchart of a second processing method for delivering multi-carriers in accordance with an embodiment of the present invention. As shown in fig. 4, the method comprises the following steps.
    Step S402, a source base station determines the target Pcell and candidate target Scell(s), and notifies a target base station to which the target Pcell and candidate target Scell(s) belong.
    In phase S404, the target base station configures the target Pcell, selects the target Scell(s) according to a Radio Resource Management (RRM) algorithm and information from a candidate target Scell(s), and configures the Scell(s) ) target.
    In Step S406, the target base station configures a corresponding handover command according to the target Pcell and the target Scell(s), and sends the handover command to the source base station.
    Phase S408, the source base station sends the handover command to a user equipment which, according to the handover command, carries out a handover process.
    In the prior art, delivery cannot be achieved in an LTE-A multi-carrier system because the source base station cannot determine which cell should be used as the delivery target cell. With this modality, the source base station determines the target Pcell, and the target base station determines the target Scell(s), thus achieving delivery in a multi-carrier system.
    Preferably, in step S404, the target base station, according to the RRM algorithm, on-site aggregation information and candidate target Scell(s) information, selects the target Scell to cell that can be carrier aggregated with the Target Pcell.
    Preferably, in phase S408, the user equipment performs a random access according to the target Pcell indicated in the delivery command; consequently, the user equipment carries out data transmission with the target Pcell and the target Scell(s).
    Preferably, in step S402, the source base station notifies the target base station via a delivery request message during the delivery of X2; in phase S406, the target base station directly sends the handover command to the source base station during the handover of X2. With the preferred mode, an X2 delivery process in the multi-carrier system can be achieved.
    Preferably, in step S402, the source base station notifies the target base station via a delivery request message via a Mobility Management Entity during the delivery of S1; in phase S406, the target base station sends the handover command to the source base station via the Mobility Management Entity during the handover of S1. With the preferred modality, a delivery process of S1 in the multi-conveyor system can be achieved.
    The process of implementing this modality will be described in detail below. In this mode, the settings of the source base station and the target base station are the same as in mode 1, which will not be repeated here.
    The difference between Modality 2 and Modality 1 is that: if the Aggregation Information of the adjacent base stations cannot be obtained by the S-eNB through the pre-configuration mode or the auto-configuration mode, only the base station itself knows the your own Aggregation Information. Therefore, the delivery phases include that: the source base station determines the target Pcell, and notifies the target Pcell and other possible target cells (possible Scell) to the target base station through an S1/X2 delivery process; the target base station prepares resources according to the Pcell determined by the source base station, and selects, from the other possible target cells transmitted by the source base station, an appropriate Scell that can be carrier-aggregated with the Pcell; the target base station configures the corresponding delivery command according to the final PCell and Scell; the source base station sends the handover command to the UE that performs a random access according to the target Pcell indicated in the handover command and performs the handover.
    As the S-eNB does not know the Aggregation Information of the T-eNB, when the UE triggers handover, such as the UE triggers a measurement reporting event A3, and assumes that the S-eNB reports that the adjacent cell Cell2- 2 is better than current Pcell, ie CelH-1. In this situation, the S-eNB can determine that the target Pcell is Cell2-2, but it cannot determine which cells among Cell1-2, Cell3-2 and Cell4-2 can be transported aggregated with Cell2-2 . The S-eNB determines to perform delivery, whereby, if a delivery of X2 is performed, it is specified in a delivery request message that the Target Cell ID of the target cell is Cell2-2. In LTE-A, the T-eNB interprets the Target Cell ID as the one that the S-eNB requests the target Pcell to be the Cell2-2, and carries a KeNB* generated by parameters provided by Cell2-2 and a Next hop Chaining Count (NCC) corresponding to KeNB* in the Information of
    AS Security. The S-eNB will also specify that the possible target Scell is CelH-2, Cell3-2 and Cell4-2 in Delivery Preparation Information carried in an RRC context in AS Security Information. If the UE also previously reported a measurement report where the signals from CelH-2, Cell3-2 and Cell4-2 become better, the S-eNB can select a possible target Scell, according to the report of measurement of the UE to ensure that the T-eNB can select target Scell(s) from cells receivable by the UE. If an S1 Delivery is performed, similar to Modality 1, the S-eNB fills in the T-eNB eNB ID in the Target ID in the Delivery Request message and transports the Transparent Recipient from Source eNB to target eNB in a Transparent Recipient from Source to Target, where the Target Cell ID and the RRC container thereof have the same content as the Target Cell ID and RRC context in a Delivery Request of the X2 delivery mentioned above. The MME will forward the Transparent Recipient from Source eNB to target eNB to the T-eNB via the Delivery Request according to the Target ID.
    Upon receiving the delivery settings from the S-eNB via the X2 Delivery Request or the S1 Delivery Request, the T-eNB specifies Cell2-2 as the target Pcell and specifies three cells, including the CelH-2, the Cell3-2 and Cell4-2, as possible target Scells. The T-eNB looks for a cell that can be transported aggregated with the Pcell CelH-2 requested by the S-eNB according to its own Aggregation Information. In the present embodiment, CelH-2 and Cell4-2 can be carrier-aggregated with Cell2-2. The T-eNB prepares corresponding resources according to the Pcell Cell2-2 specified by the S-eNB and the Scell CelH-2 and the Scell Cell4-2 selected by it as the carrier settings, and configures a Uu interface delivery command properly. It is specified in the handover command that the UE requests a handover, and that Cell2-2 is the target Pcell, and CellH-2 and Cell4-2 are the target Scells. The related configuration information of the carriers is also specified in the delivery command. If the delivery of X2 is performed, the T-eNB conveys the delivery command via the information element “Transparent Container from Target eNB to Source ENB” in the Delivery Request Confirmation. If the delivery of S1 is performed, the T-eNB sends the Delivery Request Confirmation to the MME via a “Transparent Container from Target to Source” which carries the above information element “Transparent Container from Target eNB to Source eNB” , and the MME forwards the Delivery Request Confirmation to the S-eNB via the delivery command. If a reception failure occurs on the T-eNB, for example, Pcell's local resource is limited, it needs to respond to the failure response message. In the case of X2's delivery, a Delivery Preparation Failure is responded to for the S-eNB. While in the case of S1's delivery, a Delivery Failure is responded to, and, after receiving the response, the MME forwards a Delivery Preparation Failure to the S-eNB.
    The S-eNB receives the handover command sent from the T-eNB (or forwarded by the MME), and sends the handover command to the UE via the RRC Connection Reset command of an air interface. The UE, according to the Cell2-2 target Pcell specified in the message, initiates a random access on Cell2-2. Upon success, the UE sends a "RRC Connection Reset Complete" message to the T-eNB. The T-eNB, after receiving said message, releases resources from the S-eNB, which is the same as the subsequent LTE flow.
    According to an embodiment of the present invention, a processing system for delivering multi-carriers is provided. Fig. 5 is a structural block diagram of a second processing system for delivering multi-carriers in accordance with an embodiment of the present invention. As shown in fig. 5, the system comprises a source base station 2, a target base station 4 and a user equipment 6, wherein: the source base station 2 comprises: a second determination module 12, which is adapted to determine the target Pcell and the Candidate target cell(s); a second notification module 14, which is connected to the second determination module 12 and adapted to notify the determined result determined by the second determination module 12 to the target base station to which the target Pcell and the candidate target Scell(s) belong ; a second receiving module 16, which is adapted to receive a handover command from a target base station; and a second forwarding module 18, which is connected to the second receiving module 16 and adapted to forward the delivery command to the user equipment; the target base station 4 comprises: a sixth receiving module 30, which is connected to the second reporting module 14 and adapted to receive the determined result from the second reporting module 14; a second selection module 32, which is connected to the sixth receive module 30 and adapted to select the target Scell(s) according to an RRM algorithm and the information of a candidate target Scell; a second configuration module 34, which is connected with the sixth reception module 30 and the second selection module 32, and adapted to configure the target Pcell, the target Scell(s) and a corresponding delivery command; and a second sending module 36, which is connected to the second configuration module 34 and adapted to send the handover command to the source base station; and the user equipment 6 comprises: a seventh receiving module 50, which is connected to the second routing module 18 and adapted to receive the delivery command from the second routing module 18; and a second delivery module 52, which is connected to the seventh receiving module 50 and adapted to carry out a delivery process in accordance with the delivery command.
    In the prior art, delivery cannot be achieved in the LTE-A multi-carrier system because the source base station cannot determine which cell should be used as the delivery target cell. With this modality, the source base station determines the target Pcell, and the target base station determines the target Scell(s), thus achieving delivery in a multi-carrier system.
    Preferably, the second delivery module 52 performs a random access in accordance with the target Pcell indicated in the delivery command; consequently, the user equipment carries out data transmission with the target Pcell and the target Scell(s).
    Additionally, the second notification module 14 notifies the target base station via a delivery request message during the delivery of X2; the second sending module 36 directly sends the handover command to the source base station during X2 handover. With the preferred modality, an X2 delivery process on a multi-carrier system can be achieved.
    Additionally, the second notification module 14 notifies the target base station via a delivery request message via a Mobility Management Entity during the delivery of S1; the second sending module 36 sends the handover command to the source base station via the Mobility Management Entity during handover of S1. With the preferred modality, an S1 delivery process in a multi-carrier system can be achieved.
    Embodiment 3 According to an embodiment of the present invention, a processing method for delivering multi-carriers is provided. Fig. 6 is a flowchart of a third processing method for delivering multi-carriers in accordance with an embodiment of the present invention. As shown in fig. 6, the method comprises the following steps.
    Step S602, a source base station determines a candidate target Pcell and candidate target Scell(s), and notifies a target base station to which the candidate target Pcell and candidate target Scell(s) belong.
    In Phase S604, the target base station selects a target Pcell and a target Scell(s) in accordance with the information of the candidate target Pcell and the candidate target Scell(s).
    In Step S606, the target base station configures the target Pcell, the target Scell(s) and a corresponding handover command, and sends the handover command to the source base station.
    Phase S608, the source base station forwards the handover command to a user equipment which, according to the handover command, carries out a handover process.
    In the prior art, a handover cannot be achieved in the LTE-A multi-carrier system because the source base station cannot determine which cell should be used as the delivery target cell. With this modality, the target base station determines the target Pcell and the target Scell(s), thus achieving delivery of the multi-carrier system.
    Preferably, in step S604, the target base station selects the target Pcell and target Scell(s) which can be aggregated by carrier, according to the RRM algorithm, on-site resources, loading information, on-site aggregation information and the information of the candidate target Pcell and the candidate target Scell(s).
    Preferably, in phase S608, the user equipment performs a random access according to the target Pcell indicated in the delivery command; consequently, the user equipment carries out data transmission with the target Pcell and the target Scell(s).
    Preferably, in step S602, the source base station notifies the target base station via a delivery request message during the delivery of X2; in phase S606, the target base station directly sends the handover command to the source base station during the handover of X2. With the preferred modality, an X2 delivery process on a multi-carrier system can be achieved.
    Preferably, in step S602, the source base station notifies the target base station via a delivery request message via a Mobility Management Entity during the delivery of S1; in phase S606, the target base station sends the handover command to the source base station via the Mobility Management Entity during the handover of S1. With the preferred modality, an S1 delivery process in a multi-conveyor system can be achieved.
    The process of implementing this modality will be described in detail below. In an embodiment, the configurations of the source base station and the target base station are the same as in mode 1; which will not be repeated here.
    Modality 3 is similar to Modality 2 as both work for the situation that the Aggregation Information from adjacent base stations cannot be obtained by the S-eNB through the pre-configuration mode or the auto-configuration mode, and that only the same base station knows its own Aggregation Information. The difference between modality 3 and modality 2 is that: the target base station can not only select the target Secondary Cell, but can also modify the Primary Cell requested by the source base station according to its own resources and loading conditions. The delivery phases include that: the source base station determines possible target Pcells, and notifies the target base station of the possible target Pcells and other possible target cells (possible Scells) through the S1 or X2 delivery process; the target base station selects appropriate Pcell and Scell(s) according to the information of possible Pcells and Scells transmitted by the source base station, resources on site, and loading information; the target base station configures the corresponding delivery command according to the final PCell and Scell; and the source base station sends the handover command to the UE that performs a random access according to the target Pcell indicated in the handover command and performs handover.
    As the S-eNB does not know the Aggregation Information of the T-eNB, when the UE triggers handover, such as the UE triggers a measurement reporting event A3, assumes that the S-eNB reports that the adjacent cell Cell2-2 it is better than the current Pcell, that is, the CelH-1. The S-eNB can determine that the target Pcell is Cell2-2, but it cannot determine which cells among CelH-2, Cell3-2 and Cell4-2 can be transported aggregated with Cell2-2. The S-eNB determines to carry out the delivery. If an X2 delivery is performed, it is specified in a delivery request message that the Target Cell ID of the target cell is Cell2-2. In LTE-A, the T-eNB interprets the Target Cell ID as the one that the S-eNB requests the target Pcell to be the Cell2-2, and carries a KeNB* generated by parameters provided by Cell2-2 and a Next hop Chaining Count (NCC) corresponding to KeNB* in AS Security Information. The S-eNB will also specify that the possible target Scell is Cell 1-2, Cell3-2 and Cell4-2 in Delivery Preparation Information carried in an RRC context in AS Security Information. As these cells can also be selected as Pcells by the T-eNB, the S-eNB also carries the KeNB* generated by the parameters provided by CelH-2, Cell3-2 and Cell4-2, and an NCC corresponding to the KeNB* in the context of RRC. If the UE also previously reported a measurement report where the signals from CelH-2, Cell3-2 and Cell4-2 become better, the S-eNB can select a possible target Scell, according to the report of measurement of the UE to ensure that the T-eNB can select target Scell(s) from the cells receivable by the UE. If a Delivery from S1 is performed, similar to the first method, the S-eNB fills the T-eNB's eNB ID into the Target ID in a Delivery Request message and transports the Transparent Recipient from Source eNB to target eNB in a Recipient Transparent from Source to Target, where the Target Cell ID and RRC container of the same have the same content as the Target Cell ID and RRC context in the Delivery request of the X2 delivery mentioned above. The MME will send the Transparent Recipient from Source eNB to target eNB to the T-eNB via the Delivery Request according to the Target ID.
    Upon receiving the delivery settings from the S-eNB via the X2 Delivery Request or the S1 Delivery Request, the T-eNB specifies Cell2-2 as the target Pcell and specifies three cells including the CelH-2, the Cell3 -2 and Cell4-2 as the possible target Scells. The T-eNB can perform configurations based on the Pcell specified by the target base station according to its own resources, loading and the Aggregation Information corresponding to each one of the cells. This situation is similar to the modality 2 subsequent process, or can be determined to modify the Pcell specified by the S-eNB, where the new Pcell is Celi1-2 and only Cell4-2 is configured as the Scell. The T-eNB prepares the corresponding resources by taking the Pcell CelH-2 and the Scell Cell4-2 finally selected by the T-eNB as the carrier configurations, and configures a Uu interface delivery command accordingly. It is specified in the handover command that the UE requests handover, and that CellH-2 is the target Pcell and Cell4-2 is the target Scell. And the related configuration information of the two carriers is also specified in the delivery command. If the delivery of X2 is performed, the T-eNB conveys the delivery command via the information element “Transparent Container from Target eNB to Source ENB” in the Delivery Request Confirmation. If the delivery of S1 is performed, the T-eNB sends the Delivery Request Confirmation to the MME via a Transparent Container from Target to Source which carries the above information element “Transparent Container from Source eNB to Target eNB”, and the MME forwards the Delivery Request Confirmation to the S-eNB via the delivery command. If a reception failure occurs at the T-eNB, for example, an appropriate Pcell or Scell cannot be found because the resource is limited, it needs to respond to a failure response message. In the case of X2 delivery, a Delivery Preparation Failure is responded to for the S-eNB. While in the case of the delivery of S1, the Delivery Failure is responded to, and after receiving the response, the MME forwards a Delivery Preparation Failure to the S-eNB.
    The S-eNB receives the Uu interface handover command sent from the T-eNB (or forwarded by the MME), and sends it to the UE via the RRC Connection Reset command of an air interface. The UE, according to the target Pcell Cell1-2 specified in the message, initiates a random access on a Cell1-2. Upon success, the UE sends a "RRC Connection Reset Complete" message to the T-eNB. The T-eNB, after receiving said message, releases resources from the S-eNB, which is the same as the subsequent LTE flow.
    According to an embodiment of the present invention, a processing system for delivering multi-carriers is provided. Fig. 7 is a structural block diagram of a third processing system for delivering multi-carriers in accordance with an embodiment of the present invention. As shown in fig. 7, the system comprises a source base station 2, a target base station 4 and a user equipment 6, wherein: the source base station 2 comprises: a third determination module 72 which is adapted to determine a candidate target Pcell and a candidate target Scell; a third notification module 74, which is connected with the third determination module 72 and adapted to notify the determined result determined by the third determination module to the target base station to which the candidate target Pcell and the candidate target Scell(s) belong; a third receive module 76, which is adapted to receive a handover command from a target base station; and a third forwarding module 78, which is connected with the third receiving module 76 and adapted to forward the delivery command to the user equipment; the target base station 4 comprises: an eighth receiving module 82, which is connected with the third reporting module 74 and adapted to receive the determined result from the third reporting module 74; a third selection module 84, which is connected with the eighth receiving module 82, and adapted to select a target Pcell and a target Scell(s) according to on-site resources, loading information and candidate target Pcell information and the Candidate target cell(s); a third configuration module 86, which is connected with the third selection module 84 and adapted to configure the target Pcell, the target Scell(s) and a corresponding delivery command; and a third sending module 88, which is connected with the third configuration module 86 and adapted to send the handover command to the source base station; and the user equipment 6 comprises: a ninth receiving module 92, which is connected with the third forwarding module 78 and adapted to receive the delivery command from the third forwarding module 78; and a third delivery module 94, which is connected with the ninth receiving module 92 and adapted to carry out a delivery process in accordance with the delivery command.
    In the prior art, delivery cannot be achieved in the LTE-A multi-carrier system because the source base station cannot determine which cell should be used as the delivery target cell. With this modality, the target base station determines the target Pcell and the target Scell(s), thus achieving delivery into the multi-carrier system.
    Preferably, the third selection module 84, according to an RRM algorithm, resources on site, the loading information, aggregation information on site, and the candidate target Pcell and Scell(s) information selects the target Pcell and the target Scell(s) that can be aggregated by carrier.
    Preferably, the third delivery module 94 performs a random access in accordance with the target Pcell indicated in the delivery command; consequently, the user equipment carries out data transmission with the target Pcell and the target Scell(s).
    Additionally, the third notification module 74 notifies the target base station via a delivery request message during the delivery of X2; the third sending module 88 directly sends the handover command to the source base station during X2 handover. With the preferred mode, an X2 delivery process in the multi-carrier system can be achieved.
    Additionally, the third notification module 74 notifies the target base station via a delivery request message via a Mobility Management Entity during the delivery of S1; the third sending module 88 sends the handover command to the source base station via the Mobility Management Entity during handover of S1. With the preferred mode, an S1 delivery process in the multi-carrier system can be achieved.
    To summarize, with the above embodiments of the present invention, the source base station determines the target Pcell and the target Scell(s), or the source base station determines the target Pcell and the target base station determines the target Scell(s), or the target base station determines the target Pcell and the target Scell(s). Therefore, the present invention can solve the problem that delivery cannot be achieved in the LTE-A multi-carrier system because the source base station cannot determine which cell should be used as the delivery target cell and thus Achieve delivery on multi-carrier system.
