  • System and method for resolving contention among applications requiring data connections between a mobile communications device and a wireless network
    Patent number: 7474671
    Abstract: A mobile communications device (30) includes a wireless transceiver (34) operable to conduct at least two data connections between the mobile communications device (30) and a wireless network (12) wherein each of the data connections is associated with a connected application operating on the mobile communications device. A processor (32) is coupled to the wireless transceiver (34). The processor (32) is operable to process a request for a data connection for an unconnected application operable on the mobile communications device (30), to release one of the data connections associated with one of the connected applications and to establish a data connection between the mobile communications device (30) and the wireless network (12) for the unconnected application. A contention manager (86) is operable to select the connected application to be released based upon a comparison of a contention parameter associated with each of the connected applications.
