Abstract

Claims (50)

1 . A method for sending information performed by a source base station, the method comprising:

receiving a measurement report of a target Subscriber Identity Module (SIM) card reported by a multi-card terminal, wherein the multi-card terminal is a mobile terminal provided with at least two SIM cards, and the target SIM card is one of the at least two SIM cards, wherein the measurement report of the target SIM card is sent to the source base station when a signal quality of a neighboring cell measured by the multi-card terminal during movement meets a measurement report condition;

determining, according to the measurement report, that the target SIM card needs to be handed over from a source cell to a target cell, wherein the source cell is a cell provided by the source base station;

in a process of handing over the multi-card terminal from the source cell to the target cell, sending multi-card information of the multi-card terminal to a target base station to enable the target base station to identify the multi-card terminal and perform at least one of management or configuration according to the multi-card information, wherein the target base station is a base station providing the target cell, and the multi-card information comprises information related to the at least two SIM cards; and

in the process of handing over the multi-card terminal from the source cell to the target cell, providing an RRC configuration to the multi-card terminal in a handover command message, wherein the handover command message at least includes a cell ID and all information needed to access the target cell, and the handover command message is used for the multi-card terminal to access the target cell without reading system information;

wherein the multi-card information comprises at least one of:

an International Mobile Equipment Identity (IMEI) of the multi-card terminal;

identity information corresponding to the at least two SIM cards;

a Radio Resource Control (RRC) state in which the at least two SIM cards are located; or

a Time-Division Multiplexing (TDM) pattern configured for the at least two SIM cards.

2 . The method according to claim 1 , wherein the sending multi-card information of the multi-card terminal to the target base station comprises:

sending a handover request to the target base station, wherein the handover request carries the multi-card information of the multi-card terminal.

3 . The method according to claim 1 , wherein the target SIM card is a SIM card in a radio resource control connected state.

4 . A non-transitory computer-readable storage medium, storing executable instructions, the executable instructions when executed by a processor of the source base station, cause the source base station to perform the method of claim 1 .

5 . A method for receiving information performed by a target base station, the method comprising:

in a process of handing over a multi-card terminal from a source cell to a target cell, receiving multi-card information of the multi-card terminal sent by a source base station, wherein the handing over of the multi-card terminal from the source cell to the target cell is determined by the source base station based on a measurement report received from the multi-card terminal, and the measurement report is sent to the source base station when a signal quality of a neighboring cell measured by the multi-card terminal during movement meets a measurement report condition;

identifying the multi-card terminal and performing at least one of management or configuration according to the multi-card information; and

in the process of handing over the multi-card terminal from the source cell to the target cell, executing access control and providing an RRC configuration as a part of handover acknowledgement

wherein the source cell is a cell provided by the source base station, and the target cell is a cell provided by the target base station;

wherein the multi-card information comprises at least one of:

an International Mobile Equipment Identity (IMEI) of the multi-card terminal;

identity information corresponding to at least two Subscriber Identity Module (SIM) cards of the multi-card terminal;

a Radio Resource Control (RRC) state in which the at least two SIM cards are located; or

a Time-Division Multiplexing (TDM) pattern configured for the at least two SIM cards.

6 . The method according to claim 5 , wherein receiving the multi-card information of the multi-card terminal sent by the source base station comprises:

receiving a handover request (HR) sent by the source base station, wherein the handover request carries the multi-card information of the multi-card terminal.

7 . The method according to claim 5 , wherein a target SIM card among the at least two SIM cars is a SIM card in a radio resource control connected state.

8 . An access network device, the access network device comprising:

a processor; and

a memory, the memory having executable instructions stored therein,

wherein the executable instructions when executed by the processor cause the access network device to act as the target base station and perform the method of claim 5 .

9 . The access network device according to claim 8 , wherein the executable instructions further cause the access network device to:

receive a handover request (HR) sent by the source base station, wherein the handover request carries the multi-card information of the multi-card terminal.

10 . The access network device according to claim 8 , wherein a target SIM card among the at least two SIM cards is a SIM card in a radio resource control connected state.

11 . A non-transitory computer-readable storage medium, storing executable instructions, the executable instructions when executed by a processor of the target base station cause the target base station to perform the method of claim 5 .

12 . An access network device, the access network device comprising:

a processor; and

a memory, the memory having executable instructions stored therein,

wherein the processor is configured to:

receive a measurement report of a target Subscriber Identity Module (SIM) card reported by a multi-card terminal, wherein the multi-card terminal is a mobile terminal provided with at least two SIM cards, and the target SIM card is one of the at least two SIM cards, wherein the measurement report of the target SIM card is sent to a source base station when a signal quality of a neighboring cell measured by the multi-card terminal during movement meets a measurement report condition;

determine, according to the measurement report, that the target SIM card needs to be handed over from a source cell to a target cell, wherein the source cell is a cell provided by source base station;

in a process of handing over the multi-card terminal from the source cell to the target cell, send multi-card information of the multi-card terminal to a target base station to enable the target base station to identify the multi-card terminal and perform at least one of management or configuration according to the multi-card information, wherein the target base station is a base station providing the target cell, and the multi-card information comprises information related to the at least two SIM cards; and

in the process of handing over the multi-card terminal from the source cell to the target cell, provide an RRC configuration to the multi-card terminal in a handover command message, wherein the handover command message at least includes a cell ID and all information needed to access the target cell, and the handover command message is used for the multi-card terminal to access the target cell without reading system information;
