    摘要: A Dual mode mobile terminal (MT2) comprising a WLAN interface (WLAN_NIC) and a cellular radio interface (GSM_NIC) has been described wherein when receiving a Page Request message over the cellular radio interface (GSM_NIC), indicating an incoming voice call over the cellular radio interface, or upon receiving an indication from the user of the dual mode terminal to perform an outgoing voice call, performing a determination as to whether a WLAN coverage is possible from an AP providing WLAN telephony calls, and if so responding, by issuing a WLAN call message to a WLAN AP over the WLAN interface to an interworking node (IWFN). There is moreover provided an Inter-working node (IWFN) comprising a cellular control unit (CTRL_SIP), a cellular unit (GSM_U), a voice over IP unit (VO_IP) and a router (R), which upon receiving a WLAN call from a dual mode terminal via a WLAN AP, is establishing a connection against a serving mobile switching centre (S_MSC/VLR), is performing a call initiation procedure, a assign traffic channel procedure and a call confirmation and call accepted procedure between the dual mode terminal (MT2) and the serving switching mode centre (S_MSC/VLR), is initiating duplex GSM/IP translation and is routing the cellular call between the AP and the serving mobile switching centre (S_MSC).

    摘要: A network architecture comprising at least one core network, each core network comprising a number of packet data gateway access supporting nodes GASNs handling mobile user station access over an access network, said core network(s) further providing access to one or more global packet data communication networks (IN), and one or more nodes holding subscriber or mobile user station related information. The GASNs are further adapted to support intercommunication over a mobility protocol interface to, at reception of a request for change of access type from a mobile user station, establish information about the previous GASN of the mobile user station, and to, using the established information, update an established communication context concerning the mobile user station or create a new communication context concerning the mobile user station such that mobility between different access network types is enabled for a mobile user station without interruption of an ongoing session.

    摘要: The present invention relates to a wireless station, in a wireless LAN, comprising a network interface to network interface means comprising receiving/transmitting means, antenna means, at least first power supply means or energy holding means, said wireless station further supporting transmission of data in frames of variable length. Frame fragmentation is implemented by dividing a (long) frame into a number of frame fragments. Each fragment is sent as a non-fragmented frame and means are provided for controlling the length of the time periods before/between transmission of (consecutive) frame fragments in order to decrease energy consumption during a predetermined time interval.
