  • Apparatus, and associated method, for improvement in facilitating routing of data by a mobile node operable in a packet radio communication system
    Patent number: 8532055
    Abstract: Apparatus, and an associated method, for facilitating routing of data in a packet radio communication system. A clone list is downloaded to the mobile node and stored at a clone list depository thereat. The clone list includes a plurality of entries, each of which provides routing information needed to route data when the mobile node is positioned within coverage areas encompassed by differing networks. A determination is made whether the clone list includes appropriate routing information to route a data packet sent by the mobile node positioned in a particular area encompassed by a particular network portion. If the clone list includes an entry containing such information, the need separately to request such information is obviated.
