  • Presence detection for cellular and internet protocol telephony
    Patent number: 7809381
    Abstract: A telephone system supports communication with user devices over both a cellular radio network as well as over an Internet Protocol (IP) network, and enables roaming and active call handoff between cellular and IP domains. Approaches to detecting presence of a user near a suitable IP network are used in controlling transitions between the domains, for example, enabling automatic transitions between domains, and delivery of calls to a mobile user to data network devices in the vicinity of the user.
