Abstract
A mobile communications device () includes a wireless transceiver () operable to conduct at least two data connections between the mobile communications device () and a wireless network () wherein each of the data connections is associated with a connected application operating on the mobile communications device. A processor () is coupled to the wireless transceiver (). The processor () is operable to process a request for a data connection for an unconnected application operable on the mobile communications device (), 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 () and the wireless network () for the unconnected application. A contention manager () 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.
