METHOD AND SYSTEM FOR PERFORMING SERVICE ADMISSION CONTROL

摘要

A system and broadband device for performing service admission control. The system and device being configured to grant services according to their 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 and the service with high priority is granted in case a resource is not able to support both the service with low priority and the service with high priority.

1. 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 said base station device comprises:
a first communicating module configured to connect the base station to the cellular network; wherein said first communicating module is further configured to receive an admission request transmitted 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; a second communicating module configured to connect the base station device to a broadband device, the broadband device being configured to grant services according to their 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; wherein said second communicating module is further configured to send a broadband link capacity request 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; wherein said second communicating module is further configured to receive 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; wherein said second communicating module is further configured to send a capacity allocation request to the broadband device to determine whether there is capacity available on the connection between the broadband device and the broadband network; a control module configured to determine whether to grant or deny admission to the requested service based on the capacity allocation response of said broadband device; and wherein the first communicating module of the base station device is further configured to send, in response to the admission request, a service admission response to the device of the cellular network.
