Patent ID: 8379576

Claim:
A method for execution in a wireless network comprising a backhaul network and access points configured to provide wireless terminals with wireless access to the wireless network, the method comprising: receiving a new connection request for a new connection with the wireless network from a wireless terminal; based upon the new connection request: determining if the new connection satisfies at least one access link CAC (call admission control) constraint concerning capacity of external access to the wireless network by the wireless terminal; outputting a first upstream CAC communication for propagation along a path of transit links selected to handle the new connection for use in determining whether each transit link can handle a voice service associated with the new connection; outputting a second upstream CAC communication for propagation along the path of transit links selected to handle the new connection for use in determining whether each transit link can handle a data service associated with the new connection; receiving a first downstream CAC communication from a network node in the path in response to the first upstream CAC communication; receiving a second downstream CAC communication from a network node in the path in response to the second upstream CAC communication; making a first CAC decision based on the at least one access link CAC constraint and a first transit link CAC constraint, the first transit link CAC constraint based on the first downstream CAC communication; and making a second CAC decision based on the at least one access link CAC constraint and a second transit link CAC constraint, the second transit link constraint based on the second downstream CAC communication.
