Some embodiments provide a method of performing a user equipment (UE) registration. The method establishes a unique connection dedicated to the UE between the FAP and the network controller. The method receives a register request message at the network controller from the FAP through the dedicated connection.

Method and apparatus for user equipment registration

Methods and messages for performing handovers between an unlicensed mobile access network (UMAN) comprising a first radio access network and a second radio access network. URR (UMA radio resource) handover messages are exchanged between a mobile station (MS) and a UMA network controller (UNC) operating in the UMAN. The MS may access the UMAN via a wireless access point (AP) that is communicatively coupled to the UNC via an IP network. The URR handover messages are sent between the MS and the UNC using an Up interface comprising a set of layered protocols over an underlying IP transport. The handover methods include both handover from a UMAN to the second radio access network, and handover from the second radio access network to the UMAN.

Some embodiments are implemented in a communication system that includes a first communication system comprised of a licensed wireless radio access network and a core network, and a second communication system comprising a plurality of user hosted access points and a network controller. In some embodiments, each access point operates using short range licensed wireless frequencies to establish a service region. In some embodiments, the network controller communicatively couples the core network to the plurality of access points. The method enables an unauthorized user equipment to call from an access point it is not allowed to use for emergency purposes. The method receives at an access point a service request from an unauthorized user equipment with an establishment cause of emergency call. The method sends a registration request to the network controller. The method sends a message to the core network indicating the location of the user equipment.
