Patent ID: 8712411

Claim:
A method of varying a latency timer in a wireless communication system, comprising: receiving at a communication node from a first wireless device a first network identifier associated with an access node in communication with the first wireless device during the establishment of a communication session between the first wireless device and the communication node, wherein the access node is associated with a first communication network, and wherein the first network identifier indicates a network latency of the first communication network; determining at least one registration latency timer criteria based on the first network identifier; adjusting at least one registration latency timer according to the determined at least one registration latency timer criteria to complete a registration of the first wireless device with the wireless communication system; receiving at the communication node a call request comprising a second network identifier from a second wireless device in communication with a second access node associated with a second communication network; determining at least one call latency timer criteria based on the second network identifier; and adjusting at least one call latency timer according to the determined at least one call latency timer criteria to complete a call setup between the wireless device and the second wireless device.
