Abstract: A method is provided of transferring a call connection with a mobile terminal from a first network to a second network. The first network is capable of handling both circuit-switched and packet-switched modes of connection. The second network is capable of handling one of the packet-switched or circuit-switched modes of connection but not both. The terminal is capable of both packet-switched and circuit- switched call modes of connection. The method comprises the first network: identifying the location of the mobile terminal with respect to at least one of the networks, identifying the mobile terminal as being in a mode of connection not usable in the second network, instructing the mobile terminal to transfer the call connection to the other mode of connection, and transferring the call connection to the second network.

Abstract: A multicast status availability indication from an anchor (24) is provided to a plurality of base nodes (22) that are part of a multicast group serviced by the anchor (24). The availability status indication in one example is sent autonomously by the anchor (24) independent of any inquiry or attempted setup of a new session with that anchor by a base mode (22). The base modes (22) maintain a candidate anchor set that includes information regarding currently available anchors for establishing new sessions, for example.

Abstract: In the GPRS when an MS moves from a former RA to a new RA, a method of supporting mobile Internet protocol characterized in that on receipt of a routing area update message from the MS, a mobile Internet protocol agent advertisement is sent only to that MS. The move may be inter-SGN or intro-SGN or may involve a change of RNC. The method allows efficient use of radio resources.

Abstract: A method is provided of registering a mobile terminal in an area of overlapping cell coverage by first and second networks for wireless mobile telecommunications. The networks are of different types. The method comprises: storing an identifier of the mobile terminal; storing in a controller a first record of in which cell or group of cells the mobile terminal is located in the first network and a second record of in which cell or group of cells the mobile terminal is located in the second network; and providing the mobile terminal with information of both records and said identifier.

Abstract: In a telecommunications system, such as E-UTRAN, a User Equipment 6 is connected to a base station eNB 8 by an early radio bearer, which is established using preset values stored at the UE 6 and at the eNB 8. This enables data to be transferred over the radio link prior to formal establishment of a radio bearer between the UE 6 and the eNB 8.

Abstract: The present invention provides a method of operating an idle mobile unit that is capable of communicating with first and second wireless communication systems. One embodiment of the method includes providing a location update message in response to the idle mobile unit transitioning from a first tracking area associated with the second wireless communication system to a second tracking area associated with the second wireless communication system. The first and second wireless communication systems are capable of paging the idle mobile unit following the location update message.

Abstract: The present invention provides methods involving at least one mobile unit configured to receive wireless connectivity using first and second wireless communication systems that operate according to first and second radio interface technologies, respectively. The first and second radio interface technologies are different. The method may include determining, in response to the mobile unit handing off from the first to the second wireless communication system, session establishment information for the second wireless communication system based on session establishment information associated with the first wireless communication system.
