Abstract

The disclosure relates to a method and radio base station for sharing resources in a wireless communication system. The radio base station stores an identity of a first entity to which a first plurality of UEs is associated. The first plurality of UEs has full access to resources provided by the radio base station. The radio base station also stores an identity of a second entity to which a second plurality of UEs is associated. The second plurality of UEs has partial access to the resources provided by the radio base station. When the radio base station receives a request for accessing resources from a UE, it determines whether the UE is associated with the second entity, i.e. if the UE is to be handled in support mode. If the UE is associated with the second entity it means that the UE only should have partial access to the resources.

First claim

The invention claimed is:

1. A method in a first radio base station, RBS, for sharing resources between at least two entities, the first RBS provides resources to user equipments, UEs, in a cell, comprising storing an identity of at least a first entity to which a first plurality of UEs is associated, which first plurality of UEs has full access to the resources, and an identity of at least a second entity to which a second plurality of UEs is associated, which second plurality of UEs has partial access to the resources, the method comprising:
receiving, by the first RBS, a request for accessing resources from a UE,
determining, by the first RBS, that the UE is associated with the second entity,
determining, by the first RBS, a data-rate the UE would receive in a neighboring cell served by a second RBS based on at least one of a geographical distance and a radio distance of the neighboring cell where the UE has full access to resources provided by the second RBS and is in a coverage of the neighboring cell,
determining, by the first RBS, a reduced amount of resources to provide to the UE based on the determined data-rate, in response to determining that the UE is associated with the second entity, and
providing the reduced amount of resources to the UE.

2. The method according to claim 1 , further comprising determining, by the first RBS, a data-rate the UE would receive in the cell if the UE would have full access to the resources in the cell and wherein the determination of the amount of resources to provide to the UE is further based on the determined data-rate the UE would receive in the cell if the UE would have full access to the resources in the cell.

3. The method according to claim 1 , further comprising storing, by the first RBS, cell information of at least the neighboring cell, and wherein the determination of the amount of resources to provide to the UE is further based on the cell information.

4. The method according to claim 3 , wherein the cell information of the neighboring cell comprises at least one of radio characteristics, load information, and data-rates of the neighboring cell.

5. The method according to claim 3 , further comprising receiving, by the first RBS, the cell information from an operation and maintenance node or a mobile core network node or the second RBS.

6. The method according to claim 1 , wherein the determined amount of resources provided to the UE is handled with a lower priority than resources provided to a UE which is associated with the first entity, when handled in the first RBS.

7. The method according to claim 1 , further comprising receiving, by the first RBS, the identity of the first entity and the identity of the second entity from a core network node or an operation and maintenance node or the second RBS.

8. The method according to claim 1 , further comprising transferring, by the first RBS, the identity of the first entity and the identity of the second entity to another RBS when a handover is performed.

9. The method according to claim 1 , wherein the entity to which a plurality of UE is associated is a mobile network operator or a group of subscribers of a mobile network operator.

10. A radio base station, RBS, for sharing resources between at least two entities, the RBS is configured to provide resources to user equipments, UEs, in a cell and configured to store in a storage unit an identity of at least a first entity to which a first plurality of UEs is associated, which first plurality of UEs has full access to the resources, and an identity of at least a second entity to which a second plurality of UEs is associated, which second plurality of UEs has partial access to the resources, the RBS comprises
a receiver adapted to receive a request for accessing resources from a UE, the RBS further comprises, and
a processing unit adapted to:
determine that the UE is associated with the second entity;
determine a data-rate the UE would receive in a neighboring cell served by a second RBS based on at least one of a geographical distance and a radio distance of the neighboring cell where the UE has full access to resources provided by the second RBS and is in a coverage of the neighboring cell;
determine a reduced amount of resources to provide to the UE based on the determined data-rate, in response to determining that the UE is associated with the second entity; and
provide the reduced amount of resources to the UE.

11. The RBS according to claim 10 , wherein the processing unit is further adapted to determine a data-rate the UE would receive in the cell if the UE would have full access to the cell and wherein the processing unit is adapted to determine the amount of resources to provide to the UE based on the determined data-rate the UE would receive in the cell if the UE would have full access to the resources in the cell.

12. The RBS according to claim 10 , wherein the storage unit is further adapted to store cell information of at least one cell served by the second RBS to which resources the second entity has full access, and wherein the processing unit is adapted to determine the amount of resources to provide to the UE further based on the cell information.

13. The RBS according to claim 12 , wherein the cell information comprises at least one of radio characteristics of the cell, load information and data-rates provided in the cell.

14. The RBS according to claim 12 , wherein the receiver is further adapted to receive the cell information from an operation and maintenance node or a core network node or the second RBS.

15. The RBS according to claim 10 , wherein the determined amount of resources provided to the UE is handled with a lower priority than resources provided to a UE which is associated with the first entity, when handled in the RBS.

16. The RBS according to claim 10 , wherein the receiver is further adapted to receive the identity of the first entity and the identity of the second entity from a mobile core network node or an operation and maintenance node or the second RBS.

17. The RBS according to claim 10 , further comprising a transmitter adapted to transfer the identity of the first entity and the identity of the second entity to another RBS when a handover is performed.

18. The RBS according to claim 10 , wherein the entity to which a plurality of UE is associated is a mobile network operator or a group of subscribers of a mobile network operator.

19. The method according to claim 1 , wherein determining the amount of resources to provide to the UE comprises determining an amount of resources to be used to emulate a fictional link between the UE and the second RBS.
