Patent number: 8224291Abstract: A system, method, and computer readable medium for terminating calls in a network system is provided. The communication system features an IP-based femtocell system for provisioning communication services to a user equipment. The femtocell system is provisioned with a list of electronic serial numbers of user equipments that are authorized to access the femtocell system. When a call is received by the femtocell system, the femtocell system determines a directory number of a user equipment to which the call is directed. If the destination user equipment is authorized to access the femtocell system and is currently within the service area of the femtocell system, the call setup may be completed by the femtocell system without any call setup signaling being transmitted to a core telecommunication network.Type: GrantFiled: October 15, 2008Date of Patent: July 17, 2012Assignee: Airwalk Communications, Inc.Inventor: Christopher Martin Edward Osborn
