The disclosed mobile communication device, system and method permit the process of integration and/or testing of one or more new and/or evolving wireless technologies on a mobile device without complete hardware integration. To achieve this, the mobile communication device includes a wired interface configured to communicate with a separate device via a wired connection using a wired network protocol. The mobile device also includes a data plane bridge that translates data packets between the wired network protocol of the wired interface and a wireless network protocol. The wireless network protocol is used by a mobile application executing on the mobile communication device to transfer the data packets over a wireless link. The data plane bridge and wired interface permit the data packet to be transferred over the wired interface, instead of the wireless link.

A device, system and method that preserves non-volatile items during a firmware over-the-air update are described. The electronic device comprises a non-volatile memory, a FOTA client module, and back-up and restore module. The non-volatile memory comprises one or more variant non-volatile items having one or more variant offsets associated with at least one of the variant non-volatile items. The FOTA client module is configured to receive the FOTA upgrade and replace an existing firmware program resident on the electronic device. The back-up and restore module is configured to store the variant non-volatile items before the FOTA client performs the FOTA upgrade. Additionally, the back-up and restore module is configured to restore the variant non-volatile items after the FOTA client performs the FOTA upgrade. The system further comprises a server that is configured to receive the FOTA upgrade and communicate the FOTA upgrade to the electronic device.

As SIP usage becomes prolific in 3G wireless communications, challenges are presented to using the current SIP protocols for real-time communications due to the limited signaling compression offered via SIP become. Signaling introduces unwanted delays on limited bandwidth and increases the call setup time. Additionally, SIP messages are large&#x2014;from a few hundred bytes to several kilobytes&#x2014;and compression is not offered on all available fields. The invention provides for compression of the VIA field of SIP messages through several techniques and thereby achieves lower signaling delays that reduce complex call setup delays and reduce the loss of bandwidth to necessary in-call signaling.

A wireless communication device, a wireless communication system, and a method for optimizing battery power resources are described. The wireless communication device comprises a rechargeable battery, a control module, and a display. The control module is operatively coupled to the rechargeable battery and is configured to determine a first remaining battery time associated with a first operational mode, and a second remaining battery time associated with a second operational mode. The display operatively is coupled to the control module and is adapted to display both remaining battery times. The wireless communication system comprises antennas configured to communicate using both operational modes. The method comprises accessing a network system, estimating battery metrics based on current battery power, querying a table that associates battery power metrics with different radio access technologies, and generating a table output that displays the remaining battery time associated with each of the wireless technologies.

Systems and methods for the operation of a dual mode wireless communication device are provided. A wireless communication device includes a scan module, a registration module and a learning module that cooperate to allow the device to identify available radio access technologies, select a radio interface, manage the radio interface, and learn behavioral patterns that optimize operation of the dual mode device. The dual mode device maximizes the overall time it is operational on the better radio access technology while not performing unnecessary scans. This helps in improving performance, preserving battery life and enhancing the overall user experience. In operation, the dual mode device scans for available voice or data networks upon identification of a trigger event, for example, a manual instruction, a drop in signal strength, a loss of signal, a time of usage on a particular network, a battery condition, an application preference, a state of the wireless communication device, or a geographic location. Various trigger events may be stored in a data storage area on the device and new trigger events such as geographic locations where manual scans are frequently requested by the user or geographic locations where signal strength is low or the network signal is typically lost can be stored for future reference by the device in order to improve performance.
