  • Patent number: 9955392
    Abstract: Techniques for use in selecting a base station transceiver system for communication with a mobile station are described. The mobile station is connected to a first base station transceiver system, and scans to identify a second base station transceiver system for communication. The mobile station further identifies that the second base station transceiver system provides a predetermined communication service, and that the first base station transceiver system fails to provide the predetermined communication service. In response to identifying, the mobile station causes the second base station transceiver system to be selected for communication over the first base station transceiver system even if the signal quality of the second base station transceiver system is worse than that of the first base station transceiver system.

  • Patent number: 9094529
    Abstract: To provide a consistent (i.e., single-mode) user interface in each mode of operation available on a multi-mode mobile terminal, aspects of the user interface used for a second mode (e.g., the CDMA mode) are emulated by the mobile terminal when the mobile terminal is operating in a first mode (e.g., the GSM mode). Responsive to receiving, while operating in a first mode, an indication of a given user interface interaction, the multi-mode mobile terminal determines the call state. Based on the given user interface interaction and the call state, the multi-mode mobile terminal selects a candidate message corresponding to operation of the multi-mode mobile terminal in a second mode. The multi-mode mobile terminal then converts the candidate message to one or more first-mode messages and transmits the one or more first-mode messages to the MSC at the second wireless network subsystem.

  • Patent number: 8725144
    Abstract: An apparatus and method is provided for making use of black-list network information to make scanning more efficient in multi-mode mobile devices. When performing a scan for a network, if a network that is blacklisted is found, scanning is discontinued for any network that has the same radio access technology as the network that was found. Thus, excessive scanning that can be costly for the mobile device in terms of battery life and responsiveness to provide service, is avoided.

  • Patent number: 8666400
    Abstract: Systems and methods are provided for wireless network selection by multi-mode devices. A mobile device maintains an indication of any wireless network services currently provided to the mobile device. According to an embodiment of the application, the mobile device automatically scans for both GSM wireless networks and CDMA wireless networks in order to acquire a wireless network that can provide a service that is not currently provided to the mobile device. Therefore, the mobile device avoids partial service or limited service when better service is available.

  • Patent number: 8655362
    Abstract: A method and apparatus of optimizing transitioning between EVDO and CDMA 1X systems in a hybrid access terminal, the method having the steps of: preventing a reconnect data call from being sent from the hybrid access terminal. The preventing step including checking whether a transition between an EVDO and a CDMA 1X system is successful; and if not blocking the data call, and/or checking whether an EVDO received signal strength indication is greater than or equal to a receiver sensitivity on the hybrid access terminal; and if yes, allowing the hybrid access terminal to connect to the EVDO system, and/or delaying a connection timer for connecting to the EVDO system and/or applying fast dormancy to the hybrid access terminal in an EVDO state.
