ABSTRACT:
The invention is directed to enabling an serving node and a gateway node to be informed of a new route for a new node or sub-network that has become active behind a Mobile Terminal that can also act as a router. When IP level route injection occurs at the Mobile Terminal, a Modify session profile message causes insertion of a new IP address or prefix at a gateway node related to the new route. Also, the gateway node will update the serving node and the Mobile Terminal with information related to the new route or a proposed new route. The Mobile Terminal and the gateway node can share routing information over a dynamic routing protocol. Additionally, the Mobile Terminal and the gateway node can configure static routing information on routes towards each other. The new route can be added with 24.008 and/or GTP messages when initiated on the Mobile Terminal side for either the dynamic or static case.
