Abstract: There are disclosed techniques for handling emergency calls in an electronic device, such as a mobile telephone. For example, in one embodiment, upon receipt of a request at the user-interface of the device to terminate an emergency call, the device first requests confirmation that the call should be terminated. In another embodiment, once the emergency call is terminated, if an incoming call request is subsequently received within a predetermined period of time, the device establishes a voice connection with the incoming caller regardless of whether the device is instructed to establish the voice connection. In another embodiment, once the emergency call is terminated, the device remains operable to receive a subsequent incoming call regardless of whether the device is instructed otherwise.

Abstract: A mobile device operates for communications via a WLAN with use of a WLAN transceiver portion. During such operation, the mobile device performs one or more scanning operations with use of a WWAN transceiver portion for identifying a set of cell site identifications corresponding to a plurality of base stations of one or more WWANs available in a coverage region of the WLAN. The set of cell site identifications is stored in association with a WLAN profile of the WLAN. Subsequently, while the mobile device operates for communications in a WWAN, the. WLAN transceiver portion may be maintained in a low power state. During the WWAN operation, the mobile device performs one or more scanning operations with use of the WWAN transceiver portion for identifying a current set of cell site identifications corresponding to the currently-serving base station of the WWAN and one or more neighboring base stations.

Abstract: In a device communicating over a network, a proxy to delay timeout of an application on the device where the proxy is on a communications path between the application and the network, the proxy comprising means for registering a data request from the application to the network; a counter for measuring a predetermined time interval, the time interval selected to prevent timeout at the application; means to send preventative data to the application after the counter has expired but before a response is received; means for modifying a response received from the network to remove preventative data already sent to the application, creating a modified response; and means for forwarding the modified response to the application, wherein the proxy registers that a message has been sent and waits a predetermined interval, and if a response has not been received during that interval sends the preventative data to the application to delay a timeout.
