Patent ID: 8892111

Claim:
A method at a base station device for performing service admission control, said base station device being adapted to provide a service access to devices of a cellular network, said service being provided through a broadband network, wherein the method comprises: connecting to said cellular network by the base station via a first interface; receiving, by said base station device, an admission request emitted by a device of the cellular network, said admission request identifying a requested service and comprising an indication of a priority level of the requested service; connecting to a broadband device by the base station via a second interface, the broadband device being configured to grant services according to a priority level so that, when a service with low priority has been granted and a service with higher priority is requested later on, the service with low priority is cancelled in order to grant the high priority service in case the resource is not able to support both the service with low priority and the service with high priority; sending a broadband link capacity request emitted by said base station device, to the broadband device for verifying a link capacity is available on a connection between the broadband device and the broadband network for said service; connecting to the broadband network by said broadband device via a third interface; receiving, by said base station device, from the broadband device in response to the broadband link capacity request, a link capacity response conveying the link capacity available on the connection between the broadband device and the broadband network; sending a capacity allocation request by said base station device to request from the broadband device whether there is capacity available on the connection between the broadband device and the broadband network; when the link capacity is available, granting the capacity allocation request by the broadband device by taking into account the priority level of the requested service; when the link capacity is not available, denying the capacity allocation request by the broadband device by taking into account the priority level of the requested service; determining, by said base station device, whether to grant or deny admission to the requested service based on the capacity allocation response of said broadband device; and sending, in response to the admission request, a service admission response emitted by said base station device, to the device of the cellular network.
