Patent ID: 7542455

Claim:
A method of providing a communication link between a first mobile station and a second mobile station through a customer premises equipment (CPE) device, the method comprising: intercepting a call setup request to a first security gateway of an unlicensed mobile access network controller (UNC) and redirecting the call setup request to be received at a second security gateway of the CPE device, wherein: the call setup request is provided by the first mobile station, and communications from the first mobile station are redirected from the first security gateway of the UNC to the second security gateway of the CPE device; extracting an address from the call setup request, wherein the address is associated with the second mobile station; comparing the address with a plurality of records maintained by the CPE device, wherein the records identify a plurality of mobile stations registered with the CPE device; forwarding the call setup request to the second mobile station if the address corresponds to at least one of the records, wherein: the CPE device routes communications to and from the first mobile station and the second mobile station without requiring the call setup request to pass through the first security gateway, and the first mobile station and the second mobile station are in communication with the CPE device over a wireless local access network (WLAN) in accordance with an unlicensed mobile communication standard; and registering the first and second mobile stations with the CPE device prior to the intercepting, wherein: if the first mobile station attempts to register with the first security gateway of the UNC and the first mobile station is determined to be controlled by the CPE device, then the first mobile station is directed to the second security gateway of the CPE device instead of the first security gateway of the UNC, and a new internet protocol security (IPSec) security tunnel is established for the first mobile station with the second security gateway of the CPE device, making the second security gateway of the CPE device operable to authenticate the first mobile station.
