Abstract

A base station for performing admission control at a service level is provided. The base station includes a communication interface configured to receive a bearer message for a service. The base station includes a processor configured to, in response to receiving the bearer message, determine a plurality of bearers required to support the service. The processor is further configured to determine whether to admit all of the determined plurality of bearers, and in response to determining to admit all of the determined plurality of bearers, admit the service with all of the determined plurality of bearers.

First claim

1 . A base station for performing admission control at a service level, the base station comprising:
a communication interface the communication interface configured to receive a bearer message for a service; a processor, the processor configured to:
in response to receiving the bearer message, determine a plurality of bearers required to support the service;
determine whether to admit all of the determined plurality of bearers; and
in response to determining to admit all of the determined plurality of bearers, admit the service with all of the determined plurality of bearers.

2 . The base station of claim 1 , wherein the processor is further configured to, in response to determining not to admit all of the determined plurality of bearers, deny the service.

3 . The base station of claim 1 , wherein determining whether to admit all of the determined plurality of bearers includes:
determining whether resources are available for the determined plurality of bearers; and in response to determining that resources are available for all of the determined plurality of bearers, determining to admit all of the plurality of bearers.

4 . The base station of claim 1 , wherein the bearer message includes at least one service level Allocation and Retention Priority, ARP, parameter for the service, the at least one service level ARP parameter identifying an importance of the service compared to at least one other service; and
the processor is further configured to:
determine that resources are unavailable for at least one of the determined plurality of bearers;
determine whether service level pre-emption is available for the service based on the at least one service level ARP parameter;
if service level pre-emption is available, determine whether at least one other service can be preempted;
in response to determining that at least one other service can be preempted, cause resources associated with the other service to be released from the other service; and
allocate the released resources to the at least one of the determined plurality of bearers.

5 . The base station of claim 4 , wherein the at least one service level ARP parameter includes at least one of a priority level parameter, a service pre-emption capability parameter and a service pre-emption vulnerability parameter;
the priority level parameter indicating a priority of allocation and retention for the service; the service pre-emption capability parameter indicating the pre-emption capability of the request service on other services; and the service pre-emption vulnerability parameter indicating vulnerability of the service to pre-emption by other services.

6 . The base station of claim 5 , wherein the determined at least one other service that is preempted is associated with a service pre-emption vulnerability parameter that allows pre-emption and an ARP priority level parameter of the other service indicates a lower priority than the ARP priority level of the service.

7 . The base station of claim 4 , wherein the processor is further configured to:
in response to determining that at least one other service cannot be preempted, determine at least one service that allows for bearer level pre-emption; in response to determining at least one service that allows for bearer level pre-emption, perform bearer level pre-emption to preempt at least one bearer associated with the at least one service that allows for bearer level pre-emption.

8 . The base station of claim 1 , wherein the bearer message includes a service profile identifier, ID; and
the determining of the plurality of bearers required to support the service being based at least in part on the service profile ID.

9 . The base station of claim 1 , wherein the communication interface is further configured to receive a bearer modification request; and
the processor is further configured to one of allow and reject the modification to the service based at least in part on whether the service, as modified by the bearer modification request, would meet a quality of service requirement for the service.

10 . The base station of claim 8 , wherein the processor is further configured to:
determine whether to terminate at least one bearer for the service; in response to determining to terminate the at least one bearer, determine the plurality of bearers associated with the service based at least in part on the service ID; and terminate all bearers associated with the service.

11 . The base station of claim 10 , wherein the determining whether to terminate at least one bearer for the service includes determining at least one of service termination and admission rejection during service modification has occurred.

12 . The base station of claim 1 , wherein the bearer message includes at least one bearer level Allocation and Retention Priority, ARP, parameter;
the processor is further configured to determine a service profile identifier, ID, associated with the service based at least in part on the at least one bearer level ARP parameter; and the determining of the plurality of bearers required to support the service being based at least in part on the service profile ID.

13 . A method for performing admission control at a service level at a base station, the method comprising:
receiving a bearer message for a service; in response to receiving the bearer message, determining a plurality of bearers required to support the service; determining whether to admit all of the determined plurality of bearers; and in response to determining to admit all of the determined plurality of bearers, admitting the service with all of the determined plurality of bearers.

14 . The method of claim 13 , further comprising, in response to determining not to admit all of the determined plurality of bearers, denying the service.

15 . The method of claim 13 , wherein determining whether to admit all of the determined plurality of bearers includes:
determining whether resources are available for the determined plurality of bearers; and in response to determining that resources are available for all of the determined plurality of bearers, determining to admit all of the plurality of bearers.

16 . The method of claim 13 , wherein the bearer message includes at least one service level Allocation and Retention Priority, ARP, parameter for the service, the at least one service level ARP parameter identifying an importance of the service compared to at least one other service; and
the method further comprising:
determining that resources are unavailable for at least one of the determined plurality of bearers;
determining whether service level pre-emption is available for the service based on the at least one service level ARP parameter;
if service level pre-emption is available, determining whether at least one other service can be preempted;
in response to determining that at least one other service can be preempted, causing resources associated with the other service to be released; and
allocating the released resources to the at least one of the determined plurality of bearers.

17 . The method of claim 16 , wherein the at least one service level ARP parameter includes at least one of a priority level parameter, a service pre-emption capability parameter and a service pre-emption vulnerability parameter;
the priority level parameter indicating a priority of allocation and retention for the service; the service pre-emption capability parameter indicating the pre-emption capability of the request service on other services; and the service pre-emp
