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 center (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 center (S_MSC/VLR), is initiating duplex GSM/IP translation and is routing the cellular call between the AP and the serving mobile switching center (S_MSC).
摘要:
Embodiments of the present invention include a method and system for operating a dual mode terminal that includes a wireless local area network interface and a cellular radio interface. According to an embodiment, the dual mode terminal camps on the cellular radio interface when idle. When a Page Request message is received over the cellular radio interface, the terminal determines whether wireless local area network coverage is possible from an access point providing wireless local area network cellular communication. If so, the terminal processes the incoming communication request over the wireless local area network towards another party, wherein then the communication is ended, the terminal goes back to camp on the cellular channel.

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 (6) 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 (7) 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 (8) to a WLAN AP over the WLAN interface to an interworking node (IWFN). There is moreover provided an Interworking 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 (9) from a dual mode terminal via a WLAN AP, is establishing a connection against a serving mobile switching centre (S_MSC/VLR) (10,10a, 10b), is performing a call initiation procedure (12-15), a assign traffic channel procedure (16-20) and a call confirmation and call accepted procedure (22-27) between the dual mode terminal (MT2) and the serving switching mode centre (S_MSC/VLR), is initiating duplex GSM/IP translation (29) and is routing the cellular call between the AP and the serving mobile switching centre (S_MSC).
摘要:
A wireless station, in a wireless LAN, includes a network interface to a network interface device, e.g., a NIC, that includes a transceiver, an antenna, at least a first power supply or energy holder. The wireless station supports 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. The length of a time period before or between transmission of (consecutive) frame fragments is controlled in order to decrease energy consumption during a predetermined time interval.

摘要:
A method of performing selective filtering, a network comprising a station, an AP and a PAC, whereby synchronisation between the AP and the PAC is performed in order to allow filtering of messages in at least the AP or in the PAC has been provided. An AP is moreover provided being able to perform both legacy and 802.11i association and authentication, whereby if a 802.11i station is encountered, filtering is performed until a 802.11i association and authentication is successful, and if a legacy station is encountered allowing the station to initiate login procedure with a PAC, if the station is not authenticated by the PAC, filtering messages to the station in question.
