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.

Apparatus, and associated method, for improvement in facilitating routing of data by a mobile node operable in a packet radio communication system

Method, and associated apparatus, for operating a hybrid access terminal operable in a CDMA 1x/EVDO hybrid communication session system. The hybrid access terminal is operable to communicate pursuant to an EVDO communication session and to a PPP communication session. The opening and closing of the communication sessions are independent of one another. Opening of one session does not require opening of another of the sessions. And, closing of one of the sessions does not require closing of the other of the sessions.
