Apparatus, and associated method, for facilitating routing of data in a radio communication system having a mobile node capable of roaming movement
First Claim
1. A method for a mobile node to route a data message formed thereat to a network by way of one of a plurality of network portions, the mobile node associated with a home network portion of the plurality of network portions, comprising:
- generating a registration request for the network in response to a triggering event, said registration request including an identification of the home network portion and an identification of a network portion with which the mobile node is currently in communication contact, whereby routing information is determined by the network;
transmitting said generated registration request;
receiving at the mobile node a response message populated by routing information from the network;
extracting routing information from the received response message and storing said extracted routing information at the mobile node, said stored routing information identifying to the mobile node, for at least one network portion, an IP (Internet Protocol) address, port, and access point; and
forming a data message subsequent to said storing for transmission to the network, said data message comprising said stored routing information.

Abstract
Apparatus, and an associated method, for providing routing information to a mobile node operable in a radio communication system. The routing information is used by the mobile node to address data messages that are to be communicated to a relay host, or other, device. The routing information that is provided to the mobile node includes a plurality of separate routing sequences. Different ones of the routing sequences are used by the mobile node, depending upon at what location that the mobile node is positioned when the data message is sent. A registration server is used by which to create the routing information, responsive to indications of a home network associated with the mobile node and a current location of the mobile node.
