Abstract

The invention discloses a method for performing assignment for a call. The method includes: if a user initiates a call, assigning a target bearer for the call and obtaining an identifier of the target bearer; determining at least one target base station according to the identifier of the target bearer and an identifier of a base station accessed by the user, wherein the coverage of the target bearer of the at least one target base station overlaps with the coverage of a bearer, on which the call is initiated, of the base station accessed by the user, and obtaining identifier of the at least one target base station; and sending the identifier of the target bearer and the identifier of the at least one target base station to the user. The invention is capable of improving the success rate of the assignment.

Claims

1. A method for performing assignment for a call, comprising:

if a user initiates a call, assigning, by a system side, a target bearer for the call from bearers in a multibearer network with overlapping coverage according to load of each of the bearers or service type of the call, and obtaining an identifier of the target bearer, wherein any one of the bearers comprises frequency band or carrier;

determining, by the system side, at least one target base station according to the identifier of the target bearer and an identifier of a base station accessed by the user to initiate the call, wherein the coverage of the target bearer of the at least one target base station overlaps with the coverage of a bearer, on which the call is initiated, of the base station accessed by the user, and obtaining identifier of the at least one target base station; and

sending, by the system side, the identifier of the target bearer and the identifier of the at least one target base station to the user.

2. The method according to claim 1, wherein the determining, by the system side, at least one target base station according to the identifier of the target bearer and the identifier of the base station accessed by the user, and obtaining the identifier of the target base station comprises:

obtaining, by the system side, identifier of the at least one target bearer by searching preset relationships between identifier of base station accessed by the user, identifiers of target bearers, and identifier of the at least one target base station for according to the identifier of the target bearer and the identifier of the base station accessed by the user.

3. The method according to claim 2, wherein the relationships comprises indication about whether the coverage of a bearer, on which the call is initiated, of the base station accessed by the user overlaps with the coverage of the target bearer of the at least one target base station corresponding to the base station accessed by the user.

4. The method according to claim 1, wherein the obtaining, by the system side, identifier of the at least one target base station comprises:

searching, by the system side, according to the target bearer, for at least one target base station whose coverage overlaps with the coverage of the bearer, on which the call is initiated, of the base station accessed by the user, and

obtaining identifier of the at least one target base station.

5. The method according to claim 1, wherein after the sending, by the system side, the identifier of the target bearer and the identifier of the at least one target base station to the user, the method further comprises:

if the number of the at least one target base station is one, performing, by the user, a process relevant to the call on the target bearer of the at least one target base station according to the identifier of the target bearer and the identifier of the at least one target base station; and

if the number of the at least one target base station is multiple, performing, by the user, a process relevant to the call on the target bearer of each target base station according to the identifier of the target bearer and the identifier of the at least one target base station.

6. A device for performing assignment for a call, comprising:

an assignment module, configured to, when a user initiates a call, assign a target bearer for the call from bearers in a multibearer network with overlapping coverage according to a load of each of the bearers or service type of the call, and obtain identifier of the at least one target bearer, wherein any one of the bearers comprises frequency band or carrier;

an obtaining module, configured to determine at least one target base station according to the identifier of the target bearer and an identifier of a base station accessed by the user to initiate the call, wherein the coverage of the target bearer of the at least one target base station overlaps with the coverage of a bearer, on which the call is initiated, of the base station accessed by the user, and obtain an identifier of the target base station; and

a sending module, configured to send the identifier of the target bearer and the identifier of the at least one target base station to the user.

7. The device according to claim 6, wherein

the obtaining module is specifically configured to obtain identifier of the at least one target base station by searching preset relationships between identifiers of base stations accessed by the user, identifiers of at least one target bearer, and identifier of the at least one target base station according to the identifier of the target bearer and the identifier of the base station accessed by the user.

8. The device according to claim 7, wherein the relationships comprises indication about whether the coverage of a bearer, on which the call is initiated, of the base stations accessed by the user overlaps with the coverage of the target bearer of the at least one target base station corresponding to the base station accessed by the user.

9. The device according to claim 6, wherein the obtaining module is specifically configured to search, according to the target bearer, for at least one target base station whose coverage overlaps with the coverage of the bearer, on which the call is initiated, of the base station accessed by the user, and obtain the identifier of the at least one target base station.

10. A computer program product comprising a computer readable storage medium storing program code thereon for use by a communication node for performing assignment for a call, the program code comprising instructions for executing a method that comprises:

if a user initiates a call, assigning a target bearer for the call from bearers in a multibearer network with overlapping coverage according to load of each of the bearers or service type of the call, and obtaining an identifier of the target bearer, wherein any one of the bearers comprises frequency band or carrier;

determining at least one target base station according to the identifier of the target bearer and an identifier of a base station accessed by the user to initiate the call, wherein the coverage of the target bearer of the at least one target base station overlaps with the coverage of a bearer, on which the call is initiated, of the base station accessed by the user, and obtaining identifier of the at least one target base station; and

sending the identifier of the target bearer and the identifier of the at least one target base station to the user.

11. The computer program product according to claim 10, wherein the determining at least one target base station according to the identifier of the target bearer and the identifier of the base station accessed by the user, and obtaining the identifier of the target base station comprises:

obtaining identifier of the at least one target bearer by searching preset relationships between identifier of base station accessed by the user, identifiers of target bearers, and identifier of the at least one target base station for according to the identifier of the target bearer and the identifier of the base station accessed by the user.

12. The computer program product according to claim 10, wherein the obtaining identifier of the at least one target base station comprises:

searching according to the target bearer, for at least one target base station whose coverage overlaps with the coverage of the bearer, on which the call is initiated, of the base station accessed by the user, and

obtaining identifier of the at least one target base station.
