Abstract
Systems and methods are provided to facilitate efficient routing of unlicensed mobile access (UMA) communications. In one implementation, a method of providing a communication link between a first mobile station and a second mobile station through a customer premises equipment (CPE) device includes intercepting a call setup request provided by the first mobile station and received at a security gateway of the CPE device. An address associated with the second mobile station may be extracted from the call setup request and the address may be compared with a plurality of records maintained by the CPE device. A call setup request may be forwarded to the second mobile station if the address corresponds to at least one of the records. The first and second mobile stations may be in communication with the CPE device over a wireless local access network (WLAN) in accordance with an unlicensed mobile communication standard.
