Abstract
Apparatus, and an associated method, by which to facilitate operation of a roaming mobile node to perform a packet communication service. When the mobile node roams beyond its home network, detection is made of the available networks in whose coverage area that the mobile node roams together with the communication capabilities of the available networks. A preferred listing stored at a storage element of the mobile node is accessed to determine if any of the available and compatible networks are listed on the preferred listing. If so, selection is made of one of the available and preferred networks. Otherwise, a network not contained in the preferred listing is selected through which to communicate.
