    Abstract: PROBLEM TO BE SOLVED: To provide a GPRS(General Packet Radio Service) telecommunication systems. SOLUTION: This invention provides the GPRS telecommunications systems comprising a plurality of networks, at least one of the networks being a home network for a subscriber associated with a mobile terminal; a node maintaining data relating to a service; one or more gateway nodes in networks other than the home networks and operated by the home network service provider, and means for enabling the gateway nodes to interact with the service data maintaining node to provide them with data and/or instructions concerning the service.

    Abstract: PROBLEM TO BE SOLVED: To provide a communication system communicating to a mobile user without becoming known a real location of the mobile to the user. SOLUTION: In a network processing a protocol Ipv6, location of a mobile node MN is hidden by providing of intermediate node IN. The node MN transmits a home address of the mobile node and a visitor identity of a calling mobile to the node IN, and transmits a communicator node address option of a called mobile as an extension header in Ipv6 header. In the packet selected for the pass from MN node to CN node, the node IN uses an extension header information as a source address and a destination address.

    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: 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: In the GPRS when a MS moves from a former routing area to a new routing area, 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 intra-SGN or may involve a change of RNC. The method allows efficient use of radio resources.

    Abstract: A communication system includes a decentralized, flat architecture where a plurality of base nodes each include controller capabilities so that a centralized base node such as a radio network controller is not required. At least one of the base nodes acts as an anchor node. The anchor node associates a time stamp with at least one packet and provides that to the plurality of base nodes. In one example, a multicast approach is used by a router device for distributing the packet and the associated time stamp to the plurality of base nodes. Each base node controls a timing of a transmission of the at least one packet over a wireless interface responsive to the associated time stamp.
