Methods and apparatus for prioritizing assignment of a packet data session for a plurality of applications of a mobile communication device

A mobile device establishes with a wireless network a packet data session associated with a first application for accessing a first communication service, as well as a packet data session associated with a second application for accessing a second communication service. In response to identifying an indication of a request for information via a third application, the mobile device causes the packet data session associated with the second application to be terminated, and establishes with the wireless network a packet data session associated with the third application for accessing a third communication service.
