Patent ID: 7023798

Claim:
A method for controlling the admission of connections in a wireless communication system between a base station and associated customer premise equipments (CPEs), including a requesting CPE, where the modulation scheme of the uplinks and downlinks can be varied over time, the method comprising; receiving a request for a new connection from a requesting CPE; summing the hard bandwidth commitments between a base station and associated CPEs, including the new connection and existing connections, based on a planned modulation scheme for each connection; determining an air link line rate between the base station and the associated CPEs; if the air link line rate exceeds the hard bandwidth commitments, accepting the new connection and determining a second hard bandwidth commitment for the existing connections between the base station and the associated CPEs based on a current modulation scheme for each connection where the current modulation scheme for at least one of the connections is different than the planned modulation scheme for that connection, else denying the new connection; if the air link line rate exceeds the second hard bandwidth commitments, allocating air link resources to the new connection; else determining whether additional air link resources are available; and if additional air link resources are availabLe, allocating the air link resources to the new connection; else suspending at least one of the existing connections between the base station and the associated CPEs.
