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.
