    摘要: A system and method of reducing the WLAN power consumption and limiting battery drain of a mobile communications device is provided. The mechanism continuously monitors for changes in the WLAN and cellular signal strength and modifies the WLAN profile scanning activity accordingly. By monitoring for changes, transitions can be detected which indicate the location of the mobile device (i.e., indoor or outdoor). An increase in cellular signal strength and a decrease in WLAN signal strength indicates the user is transitioning outdoors where WLAN coverage may be limited. To reduce battery power consumption, background scanning is suspended or its frequency significantly lowered. Moving indoors is indicated by a decrease in cellular signal strength and an increase in WLAN signal strength. Background/Connectivity scanning frequency is increased to provide shorter time-to-connect to WLAN Networks for the user within the WLAN coverage area.

    摘要: An emergency locator component for a mobile communication device enables the mobile communication device to obtain location information from other neighbouring mobile devices in the event that the mobile communication device is unable to determine its own location. The mobile communication device employs a short-range radiofrequency transceiver to broadcast a request for location information to the neighbouring mobile devices. A response containing location information may be received from another mobile device equipped with a similar emergency locator component. Accordingly, this technology enables mobile devices to exchange location information by setting up an ad-hoc network. The location information can be included, for example, in an emergency phone call to an emergency services call center.

    摘要: A method is presented for adapting the packet size for VoIP communications, determined on-the-fly by the total network delay inherent at the time of packet transmission. If network delays are small relative to the maximum permissible latency for VoIP communications, the payload size per packet may be increased to maximize efficiency for the transmitted call. Alternatively, if network delays are large, the payload size per packet may be decreased in order to assure that the perceived quality of the transmitted call is acceptable.

    摘要: Techniques for efficient scanning for WLANs based on mobile device velocity are described. In one illustrative example, a mobile device identifies whether its velocity is less than or greater than a threshold value. While it is identified that the velocity of the mobile device is less than the threshold value, the mobile device scans to search for one or more WLANs identified in a first subset of WLAN profiles (e.g. “stationary” WLANs). While it is identified that the velocity of the mobile device is greater than the threshold value, the mobile device scans to search for the one or more WLANs identified in a second subset of WLAN profiles (e.g. “mobile” WLANs). Advantageously, a suitable WLAN may be more efficiently identified with use of a technique which reduces power consumption of the mobile device.

    摘要: Techniques for use in controlling an access point mode of operation of a mobile terminal are described. Initially, the mobile terminal operates in the access point mode of operation for communication with one or more other mobile terminals. While operating in the access point mode, the mobile terminal receives, from the one or more other mobile terminals, network information comprising one or more network identifiers which identify one or more wireless networks within coverage of the one or more other mobile terminals. The mobile terminal disables the access point mode of operation in response to identifying that at least one of the received network identifiers corresponds to a predetermined wireless network or predetermined type of wireless network. In one example, the mobile terminal is operative in accordance with IEEE 802.11, the received network identifiers comprise service set identifiers (SSIDs), and the predetermined wireless network is an enterprise network.
