Abstract: A method for searching for a requested CDMA system using a receiver having an AFC circuit is described. A system acquisition scan is performed over a plurality of candidate frequencies. In the scan, a first pilot signal of a first system is detected on one of the frequencies, and information from the first system is decoded. If the first system is different from the requested system, then the first pilot signal is assigned as a first timing reference in the receiver for remaining frequencies. Subsequently, a second pilot signal of a second system is detected on another one of the frequencies, and information from the second system is decoded. If the second system is different from the requested system, and the first pilot signal fails below a predetermined threshold value, then the second pilot signal is selected as a second timing reference in the receiver for remaining frequencies.

Abstract: A mobile station includes one or more processors, a wireless transceiver coupled to the one or more processors, and a user interface which includes a visual display and a plurality of keys. The wireless transceiver is operative to receive a message which includes a telephone number string. When the message is visually displayed in the visual display, a hyperlink for the telephone number string in the message is created. The hyperlink for the telephone number string is highlighted when selected by an end user during the visual displaying of the message. In response to the a single depression of a SEND key while the hyperlink is selected, a telephone call to the telephone number string is initiated through the wireless communication network. Detection of the key is made immediately following the selection of the hyperlink without any intervening key depressions.

Abstract: Aspects relate to initiating voice calls to mobile devices from an enterprise network. In one example, a server can initiate a voice channel to a mobile device, and if the mobile device cannot be reached, an access network may redirect the call from the server to a number identified as a voicemail number; however, such number is reconfigured to instead be directed to a number located within the enterprise network. The server can monitor or receive an indication that a call is incoming, and attributable to the mobile device. If such a call is incoming or received, then the server determines that the call has failed. If the mobile device answers the call, the server can determine that the voice channel has been established, without waiting for a confirmation indication, such as a DTMF tone.

Abstract: A user interface manager, interposed between a Windows service and user interface modules that communicate with the Windows service in distinct system status scenarios, can record interaction between the Windows service and each of the user interface modules. The recorded interaction, along with information collected from the user interface modules, can be used in conjunction so that user interaction with a first one of the user interface modules may continue with a second one of the user interface modules after a switch from one system status (e.g., logged on) to another system status (e.g., locked). Alternatively, responsive to the switch from one system status to another system status the user interface manager may simply stop the executing user interface module so that the interaction may be started over in the new system status.

Abstract: A wireless communications device having a fast-receive mode for measuring received signal strength indication (RSSI) enables the device to handle higher time division multiple access (TDMA) multislot classes without requiring that the device include either a second receiver or a receiver with a more advanced and expensive phase-locked loop (PLL) design. The time to complete an RSSI measurement is reduced by initiating the sampling of signal strength before the radio transceiver is fully stabilized in the downlink mode. By initiating sampling before PLL stabilization is complete, the overall time to complete an RSSI measurement is reduced sufficiently to enable scheduling of an RSSI measurement in each GSM frame.
