  • Patent number: 8121637
    Abstract: A system and method for establishing and maintaining an “always-on” data connection to a wireless network through the use of a back off timer and a service check timer is disclosed. The back off timer is initialized to a determined value when a connection is not established. When the timer expires, a connection attempt is made. As further connection attempts are made, the back off timer is set to ever-increasing values. When the data connection is established, the service check timer is initialized. The data connection status is determined at the expiry of the service check timer. When, at the expiry of the service check timer, the data connection is determined to be lost, the connection method is employed.

  • Publication number: 20110183687
    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.

  • Patent number: 7937073
    Abstract: Methods and apparatus of a wireless portable communication device for maintaining appropriate authentication credentials for accessing a data application maintained in a service network are provided. A default access point name (APN) or network access identifier (NAI) is maintained in memory of the wireless device. The wireless device submits, via a default wireless network, the default APN or NAI for establishing a data session in the default wireless network. The wireless device is then able to receive, in the data session via the default wireless network, a message service using the common data application maintained in the service network. In response to a change in service subscription for the wireless device, the wireless device receives, via a current cellular network, a current APN or NAI and stores it in its memory. The wireless device then submits, via the current wireless network, the current APN or NAI for establishing a data session in the current wireless network.
