Abstract

The present invention relates to the field of communications technologies. A resource management method, apparatus, and system in a multi-carrier system are disclosed. The multi-carrier system includes at least one multi-carrier cell and the multi-carrier cell includes at least two single carrier establishing cooperation. The method includes the following steps: A base station measures the cooperative resource usage information of each cooperation established single carrier cell; the base station reports the cooperative resource usage information to a radio network controller for the radio network controller to perform resource management. The information measured and reported by the base station in the embodiment of the present invention can satisfy the needs of the multi-carrier performing resource management and make sure that the radio network controller can perform reasonable admission control over multi-carrier UEs.

Claims

1. A resource management method in a multi-carrier system, wherein the multi-carrier system comprises at least one multi-carrier cell, the at least one multi-carrier cell comprises at least two cooperation established single carrier cells, and the method comprising:

measuring by a base station, cooperative resource usage of all multi-carrier user equipments (UEs) corresponding to an identical Scheduling Priority Indicator (SPI) in each of the at least two cooperation established single carrier cells or in a resource pool, wherein the cooperative resource usage is indicative of usage and services provided to the all multi-carrier UEs in each of the at least two cooperation established single carrier cells, and if main carrier resources of a single carrier cell belong to non-cooperative resources, usage of the non-cooperative resource comprises usage of the main carrier resources; and

reporting by the base station, the cooperative resource usage in each of the at least two cooperation established single carrier cells to a radio network controller (RNC) for performing resource management on each of the at least two cooperation established single carrier cells.

2. The resource management method according to claim 1,

before the measuring by the base station, the method further comprising:

combining the cooperative resources in each of the at least two cooperation established single carrier cells into the resource pool;

wherein the measuring comprising measuring the cooperative resource usage of the resource pool.

3. The resource management method according to claim 1, further comprising:

measuring and reporting by the base station, the usage of the non-cooperative resources of each of the at least two cooperation established single carrier cells for the RNC to perform resource management.

4. The resource management method according to claim 1, wherein the usage of the non-cooperative resources comprises:

resource usage of all single carrier UEs corresponding to the identical SPI in each of the at least two cooperation established single carrier cells.

5. The resource management method according to claim 1, wherein:

the measuring of the cooperative resource usage of each single carrier cell, comprises;

measuring and reporting by the base station, a number of all UEs and a number of multi-carrier UEs on a carrier of each of the at least two cooperation established single carrier cells.

6. The resource management method according to claim 1, wherein the performing of resource management comprises:

performing by the RNC, admission control over the single carrier UEs or the multi-carrier UEs in the multi-carrier cell, or reconfiguring resources of the at least two cooperation established single carrier cells according to;

the cooperative resource usage and the usage of the non-cooperative resources usages of each single carrier cell, and a number of all the UEs and a number of the multi-carrier UEs on carriers of each single carrier cell.

7. A base station in a multi-carrier system, wherein the multi-carrier system comprises at least two cooperation established single carrier cells, the base station comprises:

a cooperative resource measuring module, configured to measure cooperative resource usage of all multi-carrier user equipments (UEs) corresponding to an identical Scheduling Priority Indicator (SPI) in each of the at least two cooperation established single carrier cells or in a resource pool, wherein the cooperative resource usage is indicative of usage and services provided to the all multi-carrier UEs in each of the at least two cooperation established single carrier cells, and if main carrier resources of a single carrier cell belong to non-cooperative resources, usage of the non-cooperative resource comprises usage of the main carrier resources; and

a reporting module, configured to report to a radio network controller (RNC), the measured cooperative resource usage is utilized by the RNC for performing resource management to each of the at least two cooperation established single carrier cells.

8. The base station according to claim 7, further comprises:

a cooperative resource setup module, configured to set up the multi-carrier cell and configure the cooperative resources of each of the at least two single cooperation established carrier cells in the multi- carrier cell.

9. The base station according to claim 8, further comprises:

a resource pool setup module, configured to consolidate the cooperative resources of the at least two cooperation established single carrier cells into the resource pool; and

the cooperative resource measuring module, configured to measure the cooperative resource usage of the resource pool established by the resource pool setup module.

10. The base station according to claim 7, further comprises:

a non-cooperative resource measuring module, configured to measure the usage of the non-cooperative resource in each of the at least two cooperation established single carrier cells;

the reporting module, further configured to report the usage of the non-cooperative resource measured by the non-cooperative resource measuring module to the radio network controller (RNC).

11. The base station according to claim 7, further comprises:

a user equipment (UE) number measuring module, configured to measure a number of all UEs and a number of multi-carrier UEs on each of the at least two cooperation established single carrier cells; and

the reporting module, further configured to report the number of all the UEs and the number of the multi-carrier UEs measured by the UE number measuring module to the RNC.

12. A resource management system in a multi-carrier system, wherein the multi-carrier system comprises at least one multi-carrier cell, the multi-carrier cell comprises at least two cooperation established single carrier cells, resources in the single carrier cell include cooperative resources for providing services to a multi-carrier user equipment (UE) and non-cooperative resources for providing services to a single carrier UE residing in the single carrier cell, and the resource management system comprises:

a base station, configured to;

measure cooperative resource usage of all multi-carrier user equipments (UEs) corresponding to an identical Scheduling Priority Indicator (SPI) in each of the at least two cooperation established single carrier cells or in a resource pool, wherein the cooperative resource usage is indicative of usage and services provided to the all multi-carrier UEs in each of the at least two cooperation established single carrier cells, and if main carrier resources of a single carrier cell belong to non-cooperative resources, usage of the non-cooperative resource comprises usage of the main carrier resources; and

report the cooperative resource usage to a radio network controller (RNC) for performing resource management to each of the at least two cooperation established single carrier cells.
