摘要:
When setting up communication from a user equipment UE (1), such as for providing IP access for the UE in order to allow it to use some service, information or an indication of at least one network property relating to a first network, e.g. the current access network (3, 3′), is sent to the UE from a node (13) in a second network such as the home network (5) of the subscriber of the UE. The information or indication can be sent in a first stage of an authentication procedure being part of the setting up of a connection from the UE. In particular, the network property can indicate whether the access network (3, 3′) is trusted or not.
摘要:
A technique for registering a mobile terminal with an anchor node and for handling data packets after registration is provided. A method implementation of this technique comprises the steps of providing support for a plurality of mobility management protocols, wherein the mobility management protocols are deployed in parallel within a protocol stack of an anchor node, receiving, from a mobile terminal, a registration message, and selectively handling the registration message in accordance with the mobility management protocol associated with the registration message.
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:
In one aspect of the invention, a system and method reduce central database signalling. The system and method select a gateway in response to an event; determine whether to transmit a gateway identifier identifying the selected gateway to a central database; and indicate whether the gateway identifier has been transmitted to the central database.
摘要:
A method, infrastructure node (11, 12, 202), and mobile node (1) arranged to hide topology information from the user and mobile node by translating topology information to non-topology related address information and using session management messages of a first communication protocol as bearer for Internet Protocol mobility messages relating to a second communication protocol.
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:
A method for providing quality of services of at least one mobile terminal in a wireless network, such as a 802.11 wireless network, wherein a service proxy functionality within an access point of the network or another entity provide quality of service operations to the at least one mobile terminal.
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.
