1. A method for managing real-time bandwidth requests in a wireless network, comprising:
- receiving a plurality of bandwidth requests each for a connection to a cell of a wireless network, each request selected from the group consisting of a call admission request, an additional bandwidth request, and a handoff request, each received request including subscription level information comprising a class of service (CoS);
determining a priority associated with the connection based on the subscription level information;
queuing each of the requests in one of a plurality of queues corresponding to the CoS for the connection based on the subscription level information;
clearing from the queues any request reaching a delay threshold; and
processing the received requests in the queues by queue beginning with a queue corresponding to a highest priority CoS and in a descending order of CoS priority to provide bandwidth to corresponding connections until available bandwidth is exhausted.

Abstract
A method and system for managing real-time bandwidth request in a wireless network includes receiving a request for a connection for bandwidth of a cell of a wireless network. A subscription level associated with a connection is determined. The request for the connection is processed based on the subscription level.

23. A system for managing real-time bandwidth request in a wireless network, comprising:
-
logic encoded in media; and the logic operable to; receive a plurality of bandwidth requests each for a connection to a cell of a wireless network, each request selected from the group consisting of a call admission request, an additional bandwidth request, and a handoff request, each received request including subscription level information comprising a class of service (CoS); determine a priority associated with the connection based on the subscription level information; queue each of the requests in one of a plurality of queues corresponding to the CoS for the connection based on the subscription level information; clear from the queues any request reaching a delay threshold; and process the received requests in the queues by queue beginning with a queue corresponding to a highest priority CoS and in a descending order of CoS priority to provide bandwidth to corresponding connections until available bandwidth is exhausted. - View Dependent Claims (24, 25, 26, 27, 28, 29, 30, 31, 32, 33)

34. A method for admission control in a wireless network, comprising:
-
receiving a call admission request for admission of a first connection to a cell of a wireless network; retrieving a quality of service (QoS) policy for the first connection; determining a class of service (CoS) for the first connection based on the QoS policy; queuing the call admission request in a call queue corresponding to the CoS of the first connection; clearing the call admission request if a delayed threshold for the call admission request is reached; admitting the first connection if a transmit power of the cell is less than a call bandwidth blocking threshold after call admission requests in queues corresponding to a higher priority CoS have been processed and after previously received call admission request in a same queue have been processed; receiving a handoff request for admission of a second connection to the cell of the wireless network; retrieving a QoS policy for the second connection; determining a CoS for the second connection based on the QoS policy; queuing the handoff request in a handoff queue corresponding to the CoS of the second connection; clearing the handoff request if a delay threshold for the handoff request is reached; and admitting the second connection if a transmit power of the cell is less than a handoff blocking threshold after handoff requests in queues corresponding to a higher priority CoS have been processed and after previously received handoff requests in a same queue have been processed. - View Dependent Claims (35)

36. An admission controller for a wireless network node, comprising:
-
a call bandwidth control including a plurality of disparate class of service (CoS) queues and operable to queue each call admission and additional bandwidth request in a corresponding one of the CoS queues and to process call admission and additional bandwidth requests from the CoS queues by queue in order of CoS priority of the queues; and a handoff admission control comprising a plurality of disparate CoS queues and operable to queue each handoff request in a corresponding one of the CoS queues and to process handoff requests from the CoS queues by queue in order of a CoS priority of the queues.
