  • Patent number: 8548510
    Abstract: A method and apparatus are provided wherein a mobile device operates some of the time on a first network and some of the time on a second network, and wherein while handling traffic of a defined type over the first network, the mobile device selectively tunes away to the second network to see if there are any messages. The method and apparatus allow a mobile device with a single transceiver to receive CMAS alerts transmitted over a 1xRTT network while minimizing disruption to ongoing delay sensitive data applications operating on a 1xEV-DO network.

  • Patent number: 8532621
    Abstract: Techniques in a wireless device for use in accessing a common data application with a service network which is external to a plurality of wireless networks are described. The device receives a data session configuration file which includes a list of the plurality of wireless networks mapped against authentication credentials associated with each wireless network. The device communicates with a current one the wireless networks. The device selects from the list one of the authentication credentials that is associated with the current wireless network. The device submits, via the current wireless network, the selected authentication credentials for establishing a packet data session via the current wireless network. The device then accesses, via the current wireless network using the packet data session, the common data application with the service network which is external to the current wireless network.

  • Patent number: 8515391
    Abstract: In one embodiment, a scheme is provided for customization of a mobile communications device's data session retry mechanism in a wireless packet data service network. Upon detecting that a cause code has been returned by a node disposed in a wireless packet data service network, a structure is interrogated to determine if the cause code is mapped to a flag relating to the device's data session retry mechanism. Responsive to determining that the received cause code is mapped as a critical cause code, the data session retry mechanism of the mobile communications device is disabled so that further signaling messages towards the network are prevented.

  • Patent number: 8504566
    Abstract: A method provides search results for a handheld electronic device including an input apparatus having a plurality of input members, each of at least a portion of which have a plurality of characters assigned thereto. A type of the input apparatus is sent from the device to a server. The device receives a number of activations of a number of the input members, and sends the received number of activations to the server. The server determines a number of possible combinations of the characters based upon the received input apparatus type and the received number of activations, searches for a number of search results as a function of the number of possible combinations of the characters, and sends the number of search results to the device. The device receives the number of search results, and displays at least a portion of the number of search results.

  • Patent number: 8494591
    Abstract: Methods and devices for implementing subsystem or functional aspect restrictions on a wireless handheld communication device. Data defining geographical boundaries of a restricted operating area is stored on the device. The present position of the device is ascertained and a determination is made whether the device is located within the restricted operating area. A restriction on the subsystem or functional aspect is imposed when it is determined the device is within the restricted operating area. The subsystem or functional aspect restriction can be communicated to the device via a wireless communication network. Additionally, the restrictions and boundaries can be communicated to the device as part of an IT security policy.
