FIELD OF THE INVENTION
[001] The embodiments of the present invention refer to the field of mobile communication technologies, and in particular, to a transfer method and system in a relay network, a relay node, a control base station and a base station . BACKGROUND OF THE INVENTION
[002] In a mobile communication network, a mobility management entity (Mobility Management Entity; MME) is used in order to perform operations such as saving a mobility management context and user authentication on a terminal (User Equipment; UE) in a coverage area of a base station (Node B E-UTRAN; eNB). The ENB node and the MME entity are connected via an S1 interface, and the ENB nodes are connected via an X2 interface. When the UE equipment moves in a coverage area of one eNB node to a coverage area of another eNB node, the UE equipment needs to be transferred from the first eNB node to the second eNB node.
[003] In a conventional network, an ENB node and a UE equipment are connected through a wireless network, that is, a single-hop network. However, in a relay network, one or more relay nodes (Relay node; RN) are added between an ENB node and a UE equipment, and are responsible for forwarding a radio signal sent by the ENB node once or multiple times for EU equipment. Considering a simple two-hop retransmission as an example, an eNB - UE radio link is divided into two radio links, namely, the eNB - RN and RN-UE links, thus having the opportunity to replace a low link quality by two good quality links, in order to obtain better link capacity and better coverage. The RN node and a control base station (Node B E-UTRAN Donor; DeNB) that controls the RN node are connected via a radio interface S1 and an X2 interface. when node DeNB acts as an agent between node RN and an MME entity, node DeNB forwards an interface message S1 between node RN and entity MME through interface S1, and when node DeNB acts as an agent between the node RN and a base station adjacent to node RN, node DeNB forwards an interface message X2 between node RN and base stations adjacent to node RN through interface X2.
[004] In a conventional network, when no X2 interface is available between two eNB nodes for some reason, for example, when a connection between ENB nodes is interrupted due to external causes, if a UE device is transferred from an eNB node for another eNB node, the transfer needs to be performed through an interface S1 connected to the MME entity, that is, a first eNB node sends a transfer request to a second eNB node through the MME entity. However, in a relay network, when no X2 interface is available between an ENB node and a DeNB node, if a UE device is transferred from the ENB node to an RN node that is controlled by the DeNB node, since the entity MME cannot determine the DeNB node corresponding to the RN node, a transfer request cannot be sent correctly, so the transfer process cannot be executed normally.

[036] In order to make the objectives, technical solutions and advantages of the embodiments of the present invention more understandable, the technical solutions in the embodiments of the present invention will be described below, in a clearer and more comprehensive way with reference to the attached drawings. It is obvious that the embodiments to be described are only a part of rather than constituting all embodiments of the present invention. All other embodiments obtainable by persons skilled in the art based on the embodiments of the present invention, without great effort of creation, will fall within the scope of application of the present invention.
[037] Figure 1 is a flowchart of an embodiment of a transfer method in a relay network according to the present invention. As shown in Figure 1, the transfer method in a relay network provided by an embodiment of the present invention includes the following steps:
[038] Step 101: A node RN receives a first area identifier that identifies the node RN.
[039] Step 102: The RN node sends a system information broadcast message carrying the first area identifier to a UE equipment in a coverage area.
[040] Step 103: The RN node receives a transfer request message, which is forwarded by a DeNB node according to the first area identifier, and performs, according to the transfer request message, a control operation node RN in the UE equipment.
[041] In the modality of the present invention, when an interface is configured between node RN and node DeNB, node DeNB allocates the first area identifier to node RN. For example, the first area identifier may be a first evolved universal terrestrial radio access network cell global identifier (EUTRAN Network Cell Global Identifier; ECGI) or a first monitoring area identity (Monitoring Area Identity ;TAI), and so on. After receiving the first area identifier allocated by node DeNB, node RN sends a system information broadcast message carrying the first area identifier to all UE equipments in the coverage area. When a certain UE equipment which is in a connection state moves from a cell of an ENB node to a cell of the RN node, the UE equipment receives the system information broadcast message carrying the first area identifier and is sent by node RN, and presents the system information broadcast message to node ENB. In the present modality, the ENB node or an MME entity can still obtain an identifier of the DeNB node (DeNB_ID) according to the first area identifier, therefore the ENB node can still send a transfer transfer request message from the ENB node to the RN node to a DeNB node from the RN node through the MME entity. After receiving the transfer request message forwarded by the node DeNB, the node RN performs, according to the transfer request message, an access control operation to the node RN in the UE equipment.
[042] Through the transfer method in a relay network according to the modality of the present invention, when an interface is configured between node RN and node DeNB, node DeNB allocates a first area identifier that identifies node RN to node RN, so that equipment UE can be normally transferred from node ENB to node RN in the relay network.
[043] Figure 2 is a flowchart of an embodiment of another transfer method in a relay network according to the present invention. As shown in Figure 2, the method provided by an embodiment of the present invention may include the following steps:
[044] Step 201: An RN node receives a response message for an interface configuration request message from a DeNB node, the response message carrying a first ECGI identifier allocated by the DeNB node.
[045] The interface configuration request message includes an X2 interface configuration request message, and the response message includes an X2 response message corresponding to the X2 interface configuration request message. The first ECGI identifier includes a DeNB node identifier (DeNB_ID).
[046] Step 202: The RN node sends a system information broadcast message carrying the first ECGI identifier to a UE equipment in a coverage area.
[047] Step 203: The RN node receives a transfer request message that carries the first ECGI identifier and is forwarded by the DeNB node, and performs, according to the first ECGI identifier, an access control operation to the RN node in the EU equipment.
[048] In the modality of the present invention, when an X2 interface is configured between the RN node and the DeNB node, the DeNB node allocates the first ECGI identifier to the RN node. After receiving the first ECGI identifier allocated by node DeNB, node RN sends a system information broadcast message carrying the first ECGI identifier to all UE equipment in the coverage area. When a certain UE equipment which is in a connection state moves from a cell of an ENB node to a cell of the RN node, the UE equipment receives the system information broadcast message carrying the first ECGI identifier and is sent by node RN, and presents the system information broadcast message to node ENB; and node ENB further sends the transfer transfer request message from node ENB to node RN to node DeNB of node RN via the MME entity. Since the first ECGI identifier is allocated by the DeNB node, the first 20 bits represent a DeNB node identifier (DeNB_ID), so the ENB node or MME entity can obtain the DeNB_ID identifier according to the first ECGI identifier, and the node ENB sends the transfer request message to node DeNB via the MME entity. After receiving the transfer request message forwarded by the node DeNB, the node RN performs, according to the transfer request message, an access control operation to the node RN in the UE equipment.
[049] Through the transfer method in a relay network according to the modality of the present invention, when an interface is configured between node RN and node DeNB, node DeNB allocates a first ECGI identifier that identifies node RN to the node RN, so that the node ENB can obtain the identifier DeNB_ID according to the first identifier ECGI, and the UE equipment can be normally transferred from the node ENB to the node RN in the relay network.
[050] Figure 3 is a flowchart of an embodiment of another transfer method in a relay network according to the present invention. As shown in Figure 3, an embodiment of the present invention provides a transfer method in a relay network, which includes the following steps:
[051] Step 301: An RN node receives a response message for an interface configuration request message from a DeNB node, the response message carrying a first TAI identity allocated by the DeNB node.
[052] The interface configuration request message includes an X2 interface configuration request message or an S1 interface configuration request message, and the X2 interface configuration request message carries a third ECGI identifier to be reported for the DeNB node. The reply message includes an X2 reply message corresponding to the X2 interface configuration request message or an S1 reply message corresponding to the S1 interface configuration request message. The first TAI identity corresponds to a DeNB_ID identifier, uniquely.
[053] Step 302: The RN node sends a system information broadcast message carrying the first TAI identity to a UE equipment in a coverage area, the system information broadcast message also carrying a third ECGI identifier .
[054] Step 303: The RN node receives a transfer request message that carries the third ECGI identifier and is forwarded by the DeNB node, and performs, according to the third ECGI identifier, an access control operation to the RN node in the EU equipment.
[055] In the modality of the present invention, when an X2 interface is configured between the RN node and the DeNB node, the RN node presents the third ECGI identifier for the DeNB node. When an S1 interface is configured between node RN and node DeNB, node DeNB allocates the first TAI identity to node RN, and the following principles are followed when node DeNB allocates first TAI identity to node RN: different identities TAIs are allocated to the RN nodes under the different DeNB nodes, and no TAI identities shared by the DeNB nodes are allocated to the RN node. After receiving the first TAI identity allocated by the DeNB node, the RN node sends a system information broadcast message carrying the first TAI identity and the third ECGI identifier to all UE equipment in the coverage area. When a certain UE equipment which is in a connection state moves from a cell of an ENB node to a cell of the RN node, the UE equipment receives the system information broadcast message carrying the first TAI identity and the third ECGI identifier and is sent by node RN, and presents the system information broadcast message to node ENB; and node ENB further sends the transfer transfer request message from node ENB to node RN to node DeNB of node RN via the MME entity. Since the first TAI identity is corresponding to a DeNB_ID identifier uniquely, the MME entity can obtain the DeNB_ID identifier according to the first TAI identity, and send the transfer request message to the DeNB node. After receiving the transfer request message forwarded by the node DeNB, the node RN performs, according to the transfer request message, an access control operation to the node RN in the UE equipment.
[056] Through the transfer method in a relay network according to the modality of the present invention, when an interface is configured between node RN and node DeNB, node DeNB allocates a first TAI identity that identifies node RN to the node RN, so that the MME entity can obtain the identifier DeNB_ID according to the first identity TAI, and the equipment UE can be normally transferred from the node ENB to the node RN in the relay network.
[057] Figure 4 is a flowchart of an embodiment of yet another transfer method in a relay network according to the present invention. As shown in Figure 4, an embodiment of the present invention provides a transfer method in a relay network, which includes the following steps:
[058] Step 401: An RN node receives a system information broadcast message that carries a second ECGI identifier that identifies the DeNB node and is sent by a DeNB node.
[059] Step 402: The RN node sends a configuration request message that loads the second ECGI identifier to an operating administration and maintenance apparatus (Operating Administration and Maintenance; OAM).
[060] Step 403: The RN node receives a configuration response message that carries a first area identifier and is returned by the OAM device according to the second ECGI identifier, the first area identifier being a first ECGI identifier including the DeNB_ID identifier.
[061] Step 404: The RN node sends a system information broadcast message that carries a first ECGI identifier to a UE equipment in a coverage area.
[062] Step 405: The RN node receives a transfer request message that carries the first ECGI identifier and is forwarded by the DeNB node, and performs, according to the first ECGI identifier, an access control operation to the RN node in the EU equipment.
[063] Step 404 and step 405 in this modality are the same as steps 202 and 203 in the method modality shown in Figure 2, and the difference is based on the fact that, in the present modality, before an interface is configured between the RN node and the DeNB node, the RN node first receives the system information broadcast message that carries the second ECGI identifier and is sent by the DeNB node, and then sends a setup request message that carries the second ECGI identifier to the OAM apparatus, and the OAM apparatus allocates a first ECGI identifier which is not used by node DeNB to node RN in accordance with the second ECGI identifier which identifies node DeNB, so as to identify node RN. Or, when the RN node receives the system information broadcast message carrying the second ECGI identifier and is sent by the DeNB node, since the first 20 bits of the second ECGI identifier represent the DeNB_ID identifier, the RN node can directly obtain the DeNB_ID identifier, and sending the configuration request message that carries the DeNB_ID identifier to the OAM device, and the OAM device allocates the first ECGI identifier that is not used by the DeNB node to the RN node according to the DeNB_ID identifier, from in order to identify the RN node.
[064] Through the transfer method in a relay network according to the modality of the present invention, before an interface is configured between the RN node and the DeNB node, the OAM device allocates the first ECGI identifier that identifies the RN node to node RN, so that equipment UE can normally be transferred from node ENB to node RN in the relay network.
[065] Figure 5 is a flowchart of an embodiment of yet another transfer method in a relay network according to the present invention. As shown in Figure 5, an embodiment of the present invention provides a transfer method in a relay network, which includes the following steps:
[066] Step 501: An RN node receives a system information broadcast message that carries a second ECGI identifier that identifies the DeNB node and is sent by a DeNB node.
[067] Step 502: The RN node sends a configuration request message that loads the second ECGI identifier to an OAM device.
[068] Step 503: The RN node receives a configuration response message that carries a first area identifier and is returned by the OAM device according to the second ECGI identifier, the first area identifier being a corresponding first TAI identity to a DeNB_ID identifier only.
[069] Step 504: The RN node sends a system information broadcast message carrying the first TAI identity to a UE equipment in a coverage area, the system information broadcast message further carrying a third ECGI identifier to be reported to node DeNB by node RN.
[070] Step 505: The RN node receives a transfer request message that carries the third ECGI identifier and is forwarded by the DeNB node, and performs, according to the third ECGI identifier, an access control operation to the RN node in the EU equipment.
[071] Step 504 and step 505 in the present modality are the same as steps 302 and 303 in the method modality shown in Figure 3, and the difference is based on the fact that, in the present modality, before an interface is configured between the RN node and the DeNB node, the RN node first receives the system information broadcast message that carries the second ECGI identifier and is sent by the DeNB node, and then sends the setup request message that carries the second ECGI identifier to the OAM apparatus, and the OAM apparatus allocates the first TAI identity to the RN node according to the second ECGI identifier that identifies the DeNB node. Or, when the RN node receives the system information broadcast message carrying the second ECGI identifier and is sent by the DeNB node, since the first 20 bits of the second ECGI identifier represent the DeNB_ID identifier, the RN node can directly obtain the DeNB_ID identifier, and sending the setup request message carrying the DeNB_ID identifier to the OAM apparatus, and the OAM apparatus allocates the first TAI identity to the RN node according to the DeNB_ID identifier. In the above two cases, the following principles are followed when the OAM appliance allocates the first TAI identity to the RN node: different TAI identities are allocated to the RN nodes under the different DeNB nodes, and no TAI identity shared by the DeNB nodes is allocated to the RN node. The first TAI identity allocated following this principle is corresponding to a DeNB_ID identifier uniquely, so an MME entity can obtain the DeNB_ID identifier according to the first TAI identity, and send the transfer request message to the DeNB node.
[072] Through the transfer method in a relay network according to the modality of the present invention, before an interface is configured between the RN node and the DeNB node, the OAM device allocates the first TAI identity, uniquely corresponding to a node DeNB to node RN, so that equipment UE can normally be transferred from node ENB to node RN in the relay network.
[073] Figure 6 is a flowchart of an embodiment of yet another transfer method in a relay network according to the present invention. As shown in Figure 6, an embodiment of the present invention provides a transfer method in a relay network, which includes the following steps:
[074] Step 601: A DeNB node sends a response message to an RN node according to a received interface configuration request message, the response message carrying a first area identifier that identifies the RN node and is allocated to node RN.
[075] Step 602: The DeNB node receives a transfer request message sent by an MME entity according to the first area identifier, and forwards the transfer request message to the RN node, so that the RN node executes , according to the transfer request message, an access control operation to node RN in equipment UE.
[076] In the embodiment of the present invention, when an interface is configured between node RN and node DeNB, node DeNB allocates the first area identifier to node RN, for example, the first area identifier can be a first identifier ECGI or a first TAI identity. After receiving the first area identifier allocated by node DeNB, node RN sends a system information broadcast message carrying the first area identifier to all UE equipment in a coverage area. When a certain UE equipment which is in a connection state moves from a cell of an ENB node to a cell of the RN node, the UE equipment receives the system information broadcast message carrying the first area identifier, and displays the system information broadcast message to the ENB node. In the present embodiment, the ENB node or the MME entity can obtain the DeNB_ID identifier according to the first area identifier, thereby the ENB node can further send the transfer transfer request message from the ENB node to the RN node to a node DeNB from node RN through the MME entity. After receiving the transfer request message sent by the MME entity, the DeNB node forwards the transfer request message to the RN node, so that the RN node performs, according to the transfer request message, an operation of access control to the RN node in the UE equipment.
[077] Through the transfer method in a relay network according to the modality of the present invention, when an interface is configured between node RN and node DeNB, node DeNB allocates a first area identifier that identifies node RN to node RN, so that equipment UE can be normally transferred from node ENB to node RN in the relay network.
[078] In addition, the interface configuration request message includes an X2 interface configuration request message. The reply message includes an X2 reply message corresponding to the X2 interface configuration request message. The first area identifier allocated is a first ECGI identifier loaded in the X2 response message, and the first ECGI identifier includes a node identifier DeNB (DeNB_ID).
[079] In the modality of the present invention, when an X2 interface is configured between node RN and node DeNB, node DeNB allocates the first ECGI identifier to node RN. After receiving the first ECGI identifier allocated by node DeNB, node RN sends a system information broadcast message carrying the first ECGI identifier to all UE equipment in the coverage area. When a certain UE equipment which is in a connection state moves from a cell of the ENB node to a cell of the RN node, the UE equipment receives the system information broadcast message carrying the first ECGI identifier and is sent by the node RN, and presents the system information broadcast message to node ENB; and the eNB node further sends a transfer transfer request message from node ENB to node RN to node DeNB of node RN via the MME entity. Since the first ECGI identifier is allocated by the DeNB node, and the first 20 bits represent the DeNB_ID identifier, the ENB node or the MME entity can obtain the DeNB_ID identifier according to the first ECGI identifier, and the ENB node sends the message transfer request to the DeNB node via the MME entity. After receiving the transfer request message sent by the MME entity, the DeNB node forwards the transfer request message to the RN node, so that the RN node performs, according to the transfer request message, an operation of access control to the RN node in the UE equipment.
[080] In addition, the interface configuration request message includes an X2 interface configuration request message and an S1 interface configuration request message, and the X2 interface configuration request message carries a third identifier ECGI to be reported to node DeNB. The reply message includes an X2 reply message corresponding to the X2 interface configuration request message and an S1 reply message corresponding to the S1 interface configuration request message. The first allocated area identifier is a first TAI identity carried in the S1 response message, and the first TAI identity is corresponding to a DeNB_ID identifier uniquely. In parallel, after receiving the response message sent by the RN node, the DeNB node can further send a base station configuration update message to the MME entity, the base station configuration update message carrying the first TAI identity , and is used to allow the MME entity to obtain a corresponding relationship between the first TAI identity and the DeNB_ID identifier, so that when the MME entity receives the requested transfer message carrying the first TAI identity, the MME entity can obtain the corresponding DeNB_ID identifier according to the first TAI identity.
[081] In the modality of the present invention, when an X2 interface is configured between the RN node and the DeNB node, the RN node presents the third ECGI identifier for the DeNB node. When an S1 interface is configured between node RN and node DeNB, node DeNB allocates the first TAI identity to node RN, and the following principles are followed when node DeNB allocates first TAI identity to node RN: Different identities TAIs are allocated to the RN nodes under different DeNB nodes, and no TAI identities shared by the DeNB nodes are allocated to the RN node. After receiving the first TAI identity allocated by the DeNB node, the RN node sends a system information broadcast message carrying the first TAI identity and the third ECGI identifier to all UE equipment in the coverage area. When a certain UE equipment which is in a connection state moves from a cell of the node ENB to a cell of the node RN, the equipment UE receives the system information broadcast message carrying the first TAI identity and the third identifier ECGI e is sent by node RN, and presents the system information broadcast message to node ENB; and node ENB further sends the transfer transfer request message from node ENB to node RN to node DeNB of node RN via the MME entity. Since the first TAI identity is corresponding to a DeNB_ID identifier uniquely, the MME entity can obtain the DeNB_ID identifier according to the first TAI identity, and send the transfer request message to the DeNB node. After receiving the transfer request message sent by the MME entity, the DeNB node forwards the transfer request message to the RN node, so that the RN node performs, according to the transfer request message, an operation of access control to the RN node in the UE equipment.

[092] In the modality of the present invention, when an X2 interface is configured between node RN and node DeNB, node DeNB allocates the first ECGI identifier to node RN. After receiving the first ECGI identifier allocated by node DeNB, node RN sends a system information broadcast message carrying the first ECGI identifier to all UE equipment in a coverage area. When a certain UE equipment which is in a connection state moves from a cell of the ENB node to a cell of the RN node, the UE equipment receives the system information broadcast message carrying the first ECGI identifier and is sent by the node RN, and further sends a measurement report to node ENB, the measurement report carrying the first ECGI identifier obtained by the UE equipment from the system information dissemination message received from node RN; and the ENB node obtains the DeNB_ID identifier according to the first ECGI identifier, and then sends a requested transfer message to the MME entity, the requested transfer message carrying the DeNB_ID identifier and the first ECGI identifier, so that the MME entity sends the transfer transfer request message from node ENB to node RN to node DeNB of node RN. Since the first ECGI identifier is allocated by the DeNB node, and the first 20 bits represent the DeNB_ID identifier, the ENB node can obtain the DeNB_ID identifier according to the first ECGI identifier, and send the transfer request message to the node DeNB through the MME entity. After receiving the transfer request message forwarded by the node DeNB, the node RN performs, according to the transfer request message, an access control operation to the node RN in the UE equipment.
[093] Or, the ENB node may further directly send a requested transfer message that carries the first ECGI identifier to the MME entity, and then the MME entity obtains the DeNB_ID identifier included in the requested transfer message according to the first identifier ECGI, and performs subsequent operations.

After receiving the first TAI identity allocated by the DeNB node, the RN node sends a system information broadcast message carrying the first TAI identity and the third ECGI identifier to all UE equipment in a convergence area.
