  • Publication number: 20120165080
    Abstract: Generally, the present invention provides a method for detecting poor RF conditions, and entering different sleep mode levels or phases in accordance with the RF conditions to save battery power. Mobile device battery life can be conserved when the mobile device detects poor RF conditions and enters a deep sleep mode of operation. In this deep sleep mode of operation the mobile device periodically samples the RF conditions and gradually increases the period between samples when the RF conditions do not improve. Because mobility can change the RF condition for wireless devices even in areas of good RF coverage, the mobile device operating in the deep sleep mode can detect this mobility and thus enhance the probability of entering an idle state, or alternatively, entering a longer power save mode. When the RF condition improves, the mobile device exits from the deep sleep mode and returns to the idle state.

  • Patent number: 8195206
    Abstract: Methods and apparatus for providing consistency in Short Message Service (SMS) timestamp formatting (UTC or non-UTC) for mobile communication devices are disclosed. In one illustrative example, a method involves receiving an SMS message intended for a mobile communication device; identifying whether the SMS message has timestamp data formatted in Coordinated Universal Time (UTC) format or non-UTC format; converting the timestamp data from the UTC format to a non-UTC time format based on an identification that the SMS message has timestamp data formatted in the UTC format; failing to convert the timestamp data to a non-UTC time format based on an identification that the SMS message has timestamp data in the non-UTC format; and causing the SMS message to be sent to the mobile communication device.

  • Publication number: 20120088503
    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.

  • Publication number: 20120087362
    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.

  • Publication number: 20110244864
    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.

  • Publication number: 20110201295
    Abstract: A method for controlling receive diversity of an antenna system of a computer device, the antenna system including two or more antenna elements. The method includes establishing a session with a remote transmitting system and determining whether a predetermined criteria detected by the computer device is satisfied within the session. If the predetermined criteria is satisfied within the session, the method includes activating at least two of the antenna elements for receiving transmissions, enabling performance of receive diversity on the received transmissions, and performing receive diversity on the received transmissions. If the predetermined criteria is not satisfied within the session, the method includes activating at least one of the antenna elements, disabling performance of receive diversity on the received transmissions, and performing a default signal processing on the received transmissions. A mobile communication device may be used to perform the method.

  • Patent number: 7991397
    Abstract: Provided are systems and methods for generating a blacklist for femtocells. According to an embodiment of the application, a mobile device generates and maintains a femtocell blacklist including an identification of at least one femtocell to be avoided by the mobile device. Upon detecting a femtocell, the mobile device determines whether the femtocell is identified in the femtocell blacklist. If the femtocell is identified in the femtocell blacklist, then the mobile device avoids any attempt to use the femtocell. This might allow the mobile device to conserve battery power and reduce wireless communication resources. Since the femtocell blacklist is generated and maintained by the mobile device, the network infrastructure does not need to generate and manage the femtocell blacklist. Also, there is no need for the mobile device to download a femtocell blacklist or updates thereof from the network infrastructure.
