摘要:
A multi-mode mobile station is able to wirelessly communicate with a wireless wide area network (WWAN) and with a wireless local area network (WLAN). The WLAN includes a “virtual” visitor location register (VVLR) for storing information about multi-mode mobile stations being served by the WLAN. The VVLR communicates with a home location register (HLR) in the WWAN in order to facilitate roaming between the WWAN and WLAN by the multi-mode mobile station.
摘要:
A mobile station has multiple communication modules for multiple wireless communication modes. In a first wireless communication mode, the mobile station communicates with a wireless wide area network and is identified by a first, mobile directory number. In a second wireless communication mode, the mobile station communicates with a wireless local area network and is still identified by the first, mobile directory number. In a third wireless communication mode, the mobile station communicates with the wireless local area network but is identified by a second, local directory number.

摘要:
A mobile station is identified by a plurality of directory numbers. One or more of the directory numbers are associated with distinct identifier codes that identify a directory number or “personality” in transmissions over the air interface, e.g., for call origination from the mobile station and/or call termination to the mobile station. When the mobile station receives an identifier code when it receives a call, the mobile station provides a distinct user-discernible indication that is specific for that identifier code. From this distinct user-discernible indication, the use may determine which directory number is being called. When originating a call, the mobile station may transmit an identifier code to indicate which directory number to use as the calling party number.
摘要:
A telephony relay enables a portable communication device that is communicatively coupled to a packet-switched network to originate calls over a circuit-switched telephone network. The telephony relay has a first interface communicatively coupled to the packet-switched network, e.g., via a modem, and a second interface communicatively coupled to the circuit-switched telephone network, e.g., via an analog telephone line. To originate a call to a called number, the portable communication device transmits the called number to the telephony relay, via the packet-switched network. The telephony relay then uses an analog signaling format, e.g., DTMF tones, to transmit the called number to the circuit-switched telephone network. When the call is answered, the telephony relay conveys media between the portable communication device and the circuit-switched telephone network, converting between the analog format used by the circuit-switched network and the packet format used by the packet-switched network.

摘要:
A mobile station may determine its present location. The mobile station may then access a database, which correlates the mobile station's present location with a coverage area of a radio network. If the database indicates that the mobile station is within the coverage area of the radio network, the mobile station may then attempt to access the radio network and determine the radio network's availability.
摘要:
A mobile station communicating with a first radio network may detect that it has changed location and thereafter stopped moving. In response to determining that it has changed location and thereafter stopped moving, the mobile station may perform one or more predetermined actions. For example, the mobile station may be communicating with a first radio network, such as a WWAN. In response to this determination, the mobile station may check the availability of a second radio network, such as a WLAN. If the second radio network is available, the mobile station may begin accessing the second radio network for voice, data or other services.
摘要:
A mobile station communicating with a first radio network, such as a WLAN, may detect that it is communicating with an access point located at a perimeter of a coverage area of the first radio network rather than communicating with an access point located within an interior of the coverage area. The mobile station might further detect one or both of first and second directional signals transmitted from the access point. In response, the mobile station might perform one or more predetermined actions, such as checking the availability of a radio network other than the WLAN, performing a handoff, sounding an alarm or some other action.
摘要:
A system for providing coordinate-based location information may include first, second and third wireless location transmitters. The wireless location transmitters may be located at fixed positions within an enclosure, such as a building. The wireless locations transmitters may each be programmed with a respective coordinate-based location, which the wireless location transmitters can in turn wirelessly transmit to a wireless device. The wireless device can then use the three respective coordinated-based locations of the wireless location transmitters to determine a coordinate-based location for the wireless device.
