    TECHNICAL FIELD
    [001] The present invention concerns the field of communication, particularly a method and system for processing a measurement event in a multicarrier system. TECHNICAL STATUS
    [002] In the mobile communication system, to achieve the mobility requirement, after the User Equipment (UE) establishes a connection to a network in a given cell, the UE still needs to measure the signal quality of the service cell and neighboring cell in order to select an appropriate cell for delivery. Using the Evolved Universal Terrestrial Radio Access Network (EUTRAN) as an example, the specific measurement process performed by the UE in the connection state is: the network side transmits a measurement control message to the UE, where the control message measurement comprises Measure Identity (MID), event type, measurement object and attributes that need to be measured; the UE performs parameter initialization according to the measurement identity in the measurement control message and acquires the attributes and measurement result of each measurement object among all measurement objects in the measurement control message; the UE performs event evaluation for the measurement result of each measurement object according to the initialized parameters or a predetermined offset value, and determines, through the evaluation, the measurement objects that contain the activation conditions of the measurement events and have a duration greater than or equal to the triggering time (Time To Trigger - TTT) between all measurement objects; the UE puts those measurement objects (at that time the measurement objects have already been matched to cells) that contain an event trigger condition, into a cell trigger list (cellsTriggeredList) of the measurement identity corresponding to the event; and the UE generates a measurement report according to the measurement results of certain measurement objects and transmits the measurement report to the network side, the measurement objects contained in the measurement report are all acquired from the cell list of the measurement identity corresponding to the event.
    [003] In the mobile communication system, the frequency or a set of cells in the frequency forms the unit of the measurement object and the measurement configuration consists of measurement assignments. Each measurement assignment comprises a measurement identity, a measurement object and a reporting configuration (eg event trigger or periodic reporting). Here the measurement identity indicates the corresponding measurement object and the corresponding report configuration. In Long Term Evolution (LTE) system a measurement object corresponds to a frequency, and the report setup can define event report and periodic report which specifically comprises event report type or periodic report type and the corresponding parameters, for example, an event typically comprises event trigger condition, output condition, event specific offset (Thresh), event hysteresis parameter (Hys), event trigger condition duration, event offset ( Offset) and so on.
    [004] To achieve the mobility requirements of the UE under the connection state, it is necessary for the UE to measure the serving cell and the neighbor cell and report the measurement objects that reach the event activation condition. At present, some measurement events for the service cell are defined, for example, definition of the activation condition for the measurement event being the service cell signal quality greater than a predetermined offset (event A1), or being the service cell signal quality less than a predetermined offset (event A2); as for the measurement event of the neighboring cell, for example, which defines the activation condition of the measurement event as being the signal quality of the neighboring cell greater than a given offset (event A4), or as being the signal quality of the cell neighbor greater than the signal quality of the current service cell by a predetermined offset (event A3).
    [005] To measure the measurement object, different systems use different measurement methods, all of which reflect on the cell signal quality. In LTE, what the UE measures is the Received Signal Strength Reference (RSRP, the corresponding unit is dBm) or the Received Signal Quality Reference (RSRQ, the corresponding unit is dB). In WCDMA, what the UE measures is the Received Signal Code Power (RSCP, the corresponding unit is dBm) of the common pilot channel or Ec/No (indicating the power ratio of each chip in each code channel after the transmitter propagate the spectrum in contrast to the band-limited white noise power spectral density) of the common pilot channel, which has dB as a unit. When comparing the qualities of signals from different cells, the UE needs to compare the results of measurements of the same type. When the measurement object reaches the activation event condition (taking event A3 defined in LTE as an example): the signal quality of the neighboring cell is greater than the signal quality of the service cell by a given offset, being the specific mathematical description of which Mn + Ofn+Ocn-Hys>Ms + Ofs + Ocs + Off, where the parameters comprise RSRP or RSRQ (serving cell is Ms, and neighbor cell is Mn) measured by UE, and also comprises a frequency-specific offset (where the serving cell frequency is Ofs and the neighboring cell frequency is Ofs, the cell-specific offset (where the serving cell frequency is Ocs and the neighboring cell frequency is Ocs and the neighboring cell frequency is Ocn), Off is offset, and Hys is hysteresis.
    [006] To meet the demands for greater bandwidth, LTE-A (Advanced LTE - advanced long-term evolution) proposes the use of the carrier aggregation method to achieve greater bandwidth, and this time , the UE can work on multiple continuous and discontinuous carriers (each carrier is referred to as a Component Carrier), as shown in Figure 1. One of the component carriers is a Primary Component Carrier (PCC), and other carriers are Secondary Component Carriers (SCC), in which in each component carrier there is a service cell providing services to the UE, the service cell in the PCC is a Primary Service Cell (Pcell), the cell of SCC service is a Secondary Service Cell (Scell). In a single carrier system, as there is only one service cell, there is no need to indicate the service cell in the existing measurement settings (measurement object, measurement identity, report configuration). But for a multi-carrier system, as there can be multiple service cells, and different measurement assignments will be configured correspondingly with different service cells, the above does not meet the requirements, specifically the existing measurement configurations cannot distinguish between one primary service cell and a secondary service cell.

DETAILED DESCRIPTION OF EXECUTION MODES
    [023] The present invention will be described in detail below with reference to the drawings and together with the execution modes. Note that the execution modes in this application and the features in the execution modes can be combined with each other if there is no conflict.
    [024] Figure 2 is a schematic diagram of a multicarrier system according to an embodiment of the present invention. As shown in Figure 2, the multicarrier system of the embodiment of the present invention comprises: a network-side device 202 and a mobile terminal 204.
    [025] Preferably, the network-side device 202 is a base station and the UE is in the connection state, in a carrier aggregation cell dominated by the base station.
    [026] The execution mode of the present invention mainly improves the configuration and processing of the measurement event between the network-side device 202 and the mobile terminal 204. The method for processing a measurement event according to an execution mode of the The present invention will be described below in combination with the drawings and modes of execution.
    [027] Figure 3 is a flowchart of a method to process a measurement event in a multicarrier system according to an execution mode of the present invention. As shown in Figure 3, the method for processing a measurement event in a multicarrier system according to an embodiment of the present invention comprises the following steps:- S302, a mobile terminal receives a measurement assignment that is configured and transmitted by a network-side device;- S304, the mobile terminal determines a cell (or cells) to be measured in correspondence to the received measurement assignment, wherein the cell(s) to be measured is a serving cell, or a service cell and a neighboring cell. For example, in the present preferred embodiment, the cells to be measured can be a neighbor cell and a serving cell; - S306, the mobile terminal measures the acquired cell to be measured; e- S308, when the measurement result reaches a measurement event reporting condition corresponding to the received measurement assignment, the mobile terminal reports the measurement result.
    [028] In the traditional state of the art, as the single carrier only relates to a serving cell, the relevant measurement event is only related to the serving cell. However, after the introduction of carrier aggregation technology, the traditional state of the art cannot meet the requirements, specifically the existing measurement configuration cannot distinguish whether the corresponding serving cell is a primary cell or a secondary serving cell. Returning to the execution mode of the present invention, by configuring different measurement events and measurement assignments for the first serving cell and the second serving cell, the mobile terminal can determine the serving cell corresponding to the measurement assignment, thus the terminal mobile can implement measurement and reporting under multiple service cell configuration.
    [029] Preferably, the device on the network side transmits the measurement configuration to each mobile terminal through a dedicated signal.
    [030] Preferably, the serving cell is a primary serving cell or a secondary serving cell.
    [031] Preferably, before measuring the neighboring cell and the serving cell, the mobile terminal consults the network side and configures different measurement events and the corresponding measurement assignments for the primary serving cell and the secondary serving cell. In the present preferred embodiment, the mobile terminal can determine the service cell corresponding to the measurement assignment and/or the measurement event, thus the mobile terminal can implement measurement and reporting under the configuration of multiple service cells.
    [032] While the mobile terminal determines a cell to be measured corresponding to a received measurement assignment: when a measurement event corresponding to the measurement assignment is the first measurement event, the service cell corresponding to the measurement assignment is a cell primary service, where the first measurement event can only be identified by an LTE-A device; and when a measurement event corresponding to the measurement assignment is a second measurement event and the mobile terminal works in the multi-carrier aggregation state, the service cell corresponding to the measurement assignment is a secondary service cell, where the second event of measurement can be identified by an LTE device and an LTE-A device.
    [033] Preferably, the measurement object of the measurement assignment corresponding to the second measurement event is at the same frequency with the secondary service cell; and when a measurement event corresponding to the measurement assignment is a second measurement event and the mobile terminal works in single-carrier aggregation state, the serving cell corresponding to the measurement assignment is a primary serving cell.
    [034] Preferably, the method further comprises the steps in which: the mobile terminal receives a reconfiguration message transmitted by the network-side device; and when the mobile terminal is configured from multi-carrier to single-carrier, the measurement assignment corresponding to the second measurement event is eliminated; or when the mobile terminal is configured from single-carrier to multi-carrier, the measurement assignment corresponding to the second measurement event is added according to the indication of the reset message.
    [035] Preferably, after the mobile terminal receives a reconfiguration message transmitted by the network-side device, the mobile terminal performs a handover according to the reconfiguration message. When the mobile terminal is configured from multi-carrier to single-carrier, the second measurement event is changed to the first measurement event.
    [036] Through the above modes, the existing measurement event is expanded, the impact on LTE protocol is reduced, protocol modification and terminal processing are simplified as much as possible and, at the same time, the backwards compatibility of the LTE system is also assured.
    [037] Preferably, while the mobile terminal determines a cell to be measured corresponding to the measurement assignment: when the measurement assignment received is a measurement assignment of a first type, the service cell corresponding to the measurement assignment is a cell of primary service; when the received measurement assignment is a measurement assignment of a second type, the service cell corresponding to the measurement assignment is a secondary service cell; where the network-side device configures the measurement assignment of a first type related to the primary service cell and the measurement assignment of the second type related to the secondary service cell according to the measurement event, the measurement event corresponding to the measurement assignment of the first type can be identified by an LTE device and by an LTE-A device, and the measurement event corresponding to the measurement assignment of the second type can be identified only by an LTE-A device.
    [038] Preferably, under the situation where the measurement assignment received is the measurement assignment of the first type or the measurement task of the second type, the method further comprises: the mobile terminal receives a reconfiguration message transmitted by the device on the side from the Web; and when the mobile terminal is configured from multi-carrier to single-carrier, the measurement assignment of the second type is eliminated; or when the mobile terminal is configured from single-carrier to multi-carrier, the measurement assignment of the second type is added according to the indication of the reset message.
    [039] Preferably, while the mobile terminal determines a cell to be measured corresponding to the received measurement assignment: when a measurement event corresponding to a measurement assignment is a third measurement event, the service cell corresponding to the measurement assignment is a primary serving cell, where the third measurement event can only be identified by an LTE-A device; when a measurement event corresponding to a measurement assignment is a fourth measurement event, and a primary service cell or a secondary service cell exists at the frequency where the measurement object is, the service cell corresponding to the measurement assignment is the existing primary service cell or a secondary service cell; when a measurement event corresponding to a measurement assignment is the fourth measurement event, and the primary service cell and the secondary service cell do not exist at the frequency where the measurement object of the measurement assignment is, the service cell corresponding to the measurement assignment is the primary service cell; wherein the fourth measurement event can be identified by an LTE device and an LTE-A device.
    [040] Preferably, while the mobile terminal determines a cell to be measured corresponding to the measurement assignment received: when a measurement event corresponding to the measurement assignment is a fifth measurement event, the service cell corresponding to the measurement assignment is a primary service cell, wherein the fifth measurement event can only be identified by one LTE device and one LTE-A device; and when a measurement event corresponding to the measurement assignment is a sixth measurement event, the service cell corresponding to the measurement assignment is the secondary service cell; where the sixth measurement event can only be identified by an LTE-A device.
    [041] Preferably, when the measurement event corresponding to the measurement assignment is the sixth measurement event, the measurement object corresponding to the measurement assignment is at the same frequency as the secondary service cell.
    [042] In the execution modes of the present invention, the UE acquires one or more component carriers with configured measurement reference. Execution modes mainly relate to type comparison measurement events, especially event activation (referred to as protocol entry condition) is determined by wireless signals from a reference cell (service cell) and a neighboring cell , for example, in LTE, the measurement event above comprises events A3, A5 and B2, as shown in the table below:

    [043] The execution modes of the configuration methods above will be described in detail below, taking event A3 as an example. Those knowledgeable in the field can understand that the following solutions are also applicable to A5, B2 and other comparison events introduced subsequently.
    [044] Execution mode 1: on the basis of the newly defined existing A3-PCC event, the explanation of the A3 event is re-modified, and when the UE works, moving from single-carrier to multi-carrier or from multi-carrier to single-carrier, it is need to perform mutual conversion between A3 and A3-PCC.
    [045] In the present execution mode, the definitions of the A3-PCC and A3 events are shown in the table below:


    [046] In the table above, when working in the multi-carrier aggregation state, the service cell is the service cell at the frequency where the neighboring cell is, or it can be just Scell, it is indicated that: the service cell can be a primary service cell or a secondary service cell, or it can just be a secondary service cell (Scell).
    [047] As described in the table above, according to the requirement in the prior art, the newly defined A3-PCC event is that the neighbor cell is better than the primary service cell by an offset, where Ms, Ofs and Ocs are measures of Pcell quantity, Pcell frequency offset and Pcell cell offset, respectively.
    [048] To modify the original A3 event, there are different explanations for the UE in different states. When the UE is in non-carrier aggregation state, specifically the UE has only one serving cell, it can be deduced that there is only Pcell, but no Scell, the event A3 is that the neighbor cell is better than the single service cell by an offset, and the explanation is the same as the original explanation of the A3 event in LTE. When the UE is in carrier aggregation state, specifically the UE has more than one serving cell, Pcell and at least one Scell. At this time, when the measurement object corresponding to an A3 event is at the frequency that a service cell is on, the A3 event selects the service cell to provide a benchmark for the event's trigger condition.
    [049] As shown in Figure 4, the UE works in the multicarrier state, where CC1 is the frequency where the Pcell is, CC2 is the frequency where the Scell 1 is, CC3 is the frequency where the neighbor cell is, and four measurement assignments are configured, which are specifically shown in the table below:

    [050] Preferably, in the above scenario, when UE works moving from single carrier to multicarrier or from multicarrier to single carrier, it is necessary to perform mutual conversion between A3 and A3-PCC. That is, A3-PCC is only for the multicarrier state, specifically it is only used when there are multiple service cells at this time, and the A3 event is explained as a comparison event of the same Scell frequency. When the UE returns to the single-carrier state, only event A3 is used, and the explanation regarding is the same as in LTE.
    [051] Examples will be given below in two multicarrier to single carrier and single carrier to multicarrier scenarios.
    [052] Scenario 1: UE is configured from multicarrier to single carrier, Scell 1 is eliminated, thus the corresponding measurement assignment with Scell as the service cell is also eliminated, specifically measurement assignment 3 is eliminated, the deletion can be done by: the base station deletes the measurement assignment 3 by indicating in a delete reset message, or the UE automatically deletes the measurement assignment 3 corresponding to the Scell according to the base station reset, preferably the deletion of measurement assignment can be deletion of MID. The above measurement assignments are changed as shown in the table below:

    [053] To ensure UE backwards compatibility and consistency with LTE in single-carrier state, the A3-PCC event needs to be converted to an A3 event, specifically the UE should not use the A3-PCC event in single-carrier state. The A3-PCC event can be reset to an A3 event through an explicit network-side reset message, such as an RRC reset message, when the last Scell is dropped to enter the single-carrier state. In single-carrier state, the explanation of event A3 is the same as in LTE. Alternatively, the UE can implicitly automatically convert or explain the A3-PCC event to the A3 event of the LTE according to the changing state of the UE, after the last Scell (specifically ScelH) is eliminated, as shown in the table below:

    [054] Scenario 2: when the UE is in the single-carrier state, the setting is as shown in Figure 5, CC1 is the frequency the serving cell is at, the network resets the UE to the multi-carrier state based on a internal algorithm (eg UE service boost), where CC1 is Pcell, CC2 is ScelH, a same frequency measurement assignment 4 in Scell is added as shown in the table below. At this time, event A3 from original measurement assignments 1, 2 and 3 needs to be converted to event A3-PCC. Similarly, A3 to A3-PCC conversion can also use explicit network reconfiguration, or automatic implicit UE conversion as described in Scenario 1.

    [055] Execution mode 2: no new events are defined, and A3 events are classified into A3 events corresponding to Scell and A3 events corresponding to Pcell.
    [056] In the present execution mode, no new events are defined, and A3 events in LTE are classified into A3 events corresponding to Scell and A3 events corresponding to Pcell. The UE configures measurement assignments of four A3 events according to the configuration shown in Figure 6. In addition, the four A3 events are explicitly divided into groups (for example, the network indicates through a reset signaling) or by implicitly (reserving some assignments to Pcell, and the other assignments are from Scell, or vice versa), 1, 2, and 3 are assigned to Pcell and 4 is assigned to ScelH. Pcell measurement assignments can be configured according to LTE mode, specifically it can be considered as a standardized group. The Scell measurement assignment is configured via a newly added group cell, so as to ensure backwards compatibility, specifically, on return to the LTE base station, the newly added group cell may be overlooked as it cannot be identified. When a state changes from multicarrier to single carrier or a state changes from single carrier to multicarrier occurs, it is only necessary to delete or add information from the measurement assignment assigned to Scell. In the present execution mode, the cell to which the measurement assignment is assigned is the service cell of the measurement assignment. According to the groups, the four measurement assignments can be explained as shown in the table below:

    [057] Run mode 3: the A3-SCC-Pcell event is newly defined, to allow a neighboring cell at the frequency that Scell is on to be better than Pcell by an offset, and the existing A3 event is explained as: a cell neighbor at the frequency where Pcell is or at a non-setting frequency is better than Pcell by an offset, or a neighbor cell at the frequency where Scell is is better than Scell by an offset.
    [058] For the type comparison event, such as the service cell A3 event, it is determined by the stipulated rule, which is as follows: when there is Pcell or Scell in the frequency of the corresponding measurement object, Pcell or Scell is taken as service cell for activation event, in this scenario, the neighbor cell is the cell in addition to the service cell; and when there is no Pcell or Scell at the frequency of the corresponding measurement object, Pcell is taken as the service cell for event activation. The detailed description of the measurement events in the present execution mode is shown in the table below:

    [059] As shown in Figure 6, for the measurement assignment where the measurement object is the frequency where Scell is and the service cell is Pcell, A3-SCC-PcelI is used. Each measurement task is shown in the table below:

    [060] As in execution mode 1, additionally, when the UE is in the process of multicarrier to single carrier or single carrier to multicarrier reconfiguration, it is necessary to explicitly or implicitly convert A3-SCC-Pcell to A3 or convert A3 to A3 -SCC-Pcell.
    [061] Execution Mode 4: the A3-SCC event is newly defined as the neighbor cell at the frequency where Scellx is is better than Scellx by an offset, specifically A3-SCC can be configured only at the frequency where Scell is, a corresponding neighbor cell is a neighbor cell at the frequency that Scell is on and the serving cell is Scell.
    [062] The existing A3 event is explained below: a neighboring cell at a certain frequency is better than Pcell by an offset, specifically as shown in the table below:

    [063] As shown in Figure 7, the corresponding measurement assignments are configured, which are specifically shown in the table below:

    [064] When a state changes from multicarrier to single carrier or a state change from single carrier to multicarrier occurs, it is only necessary to delete or add Scell and measurement assignment information corresponding to A3-SCC, as described in execution modes 1 and 2, the elimination of the measurement assignment can be done by: the network indicates i explicitly, in a reset message, eliminating the corresponding measurement assignment while indicating the elimination of Scell; or the UE deletes the A3-SCC measurement assignment corresponding to Scell while eliminating Scell according to the network indication.
    [065] When the events involved are non-comparative type service cell measurement events, A1 and A2 are understood, as shown in the table below:

    [066] The service cell is a service cell at the frequency of the measurement object corresponding to the measurement assignment, specifically when the measurement assignment corresponds to event A1 and A2, the service cell is a service cell at the frequency of measurement object. As shown in the table below, measurement tasks 1 and 2 correspond to events A1 and A2 respectively, the service cell is a service cell in the measurement object CC1, which is Pcell in the present execution mode. Similarly, it can be understood that the serving cell of measurement assignments 3 and 4 is Scell.

    [067] Additionally, the present invention additionally provides a preferred mode of execution of the method for processing a measurement event in a multicarrier system. In the preferred execution mode, the method for processing a measurement event comprises the following steps:- S1, a mobile terminal measures a wireless signal from a neighboring cell and a service cell corresponding to a measurement event, in which the serving cell corresponding to the measurement event is a secondary serving cell and the secondary serving cell and the neighboring cell are on the same frequency; e- S2, when the wireless signal quality of the neighboring cell is higher than the wireless signal quality of the serving cell, the measurement event is activated.

However, after the introduction of carrier aggregation technology the state of the art cannot meet the requirements, specifically the existing measurement configuration cannot distinguish whether the corresponding serving cell is a primary serving cell or a secondary serving cell. Returning to the execution mode of the present invention, configuring different measurement events and measurement assignments for the primary service cell and the secondary service cell, the mobile terminal can determine the service cell corresponding to the measurement assignment, thus the mobile terminal can implement measurement and reporting under multiple service cell configuration.

    [070] Preferably, before measuring the neighboring cell and the serving cell, the mobile terminal acquires the measurement configuration transmitted by the device on the network side through a dedicated signaling, where the measurement configuration comprises: measurement assignment. The measurement task corresponds to the measurement event.
    [071] Preferably, before measuring the neighboring cell and the serving cell, the mobile terminal consults the network side and configures different measurement events and the corresponding measurement assignments for the primary serving cell and the secondary serving cell. In the present preferred execution mode, the mobile terminal can determine the service cell corresponding to the measurement assignment and/or measurement event, thus the mobile terminal can implement measurement and reporting under the configuration of multiple service cells.
    [072] Preferably, in the present preferred execution mode, the steps in which the mobile terminal determines the service cell corresponding to the measurement assignment and/or the measurement event can be understood with reference to the execution modes as shown in Figures 3 -7, will not be redundantly described here.
    [073] Preferably, in the present preferred execution mode, the process of reconfiguration of the measurement settings can also be understood with reference to the execution modes as shown in Figures 3-7, they will not be described here redundantly.

Then the 8043 measurement module measures the acquired cell to be measured; and the second transmission module 8044 reports a measurement result when the measurement result reaches an event reporting condition corresponding to the received measurement assignment.
    [079] In the execution mode of the present invention, configuring different measurement events and measurement assignments for the primary service cell and the secondary service cell, the mobile terminal can determine the service cell corresponding to the measurement assignment, thus the terminal mobile can implement measurement and reporting under multiple service cell configuration.
    [080] The 8042 acquisition module acquiring a cell (or cells) to be measured corresponding to the received measurement assignment may comprise at least one of the following items: 1) when a measurement event corresponding to the measurement assignment is a first event of measurement, the service cell corresponding to the measurement assignment is a primary service cell, wherein the first measurement event can only be identified by an LTE-A device; and when the measurement event corresponding to the measurement assignment is a second measurement event and the mobile terminal operates in the multi-carrier aggregation state, the service cell corresponding to the measurement assignment is a secondary service cell, wherein the second event measurement can be identified by an LTE device and an LTE-A device.
