US 2003/0152042 A1 · Method and system for adding IP routes to a routing mobile terminal with 3G messages

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.

A method for adding a new route for a node disposed behind a mobile terminal, wherein the mobile terminal is operable as a router for the node disposed behind the mobile terminal, comprising:

(a) in response to receiving the new route for the node disposed behind the mobile terminal, employing the mobile terminal to send an Activate session profile message to a gateway node and sending a Modify session profile message along with the new route to a serving node;
(b) enabling the serving node to record the new route and update the gateway node with the new route;
(c) employing the gateway node to determine each new route that is updateable to a routing table, wherein each updateable new route is added to the routing table and an Update session profile message along with the new route is sent to the serving node and the mobile terminal;
and
(d) employing the gateway node to determine each new route that is un-updateable to the routing table, wherein if the gateway node is unable to propose another new route that is updateable to the routing table for the node disposed behind the mobile terminal, employing the gateway node to send an error message to the serving node and the mobile terminal, and wherein if the gateway node does propose the other new route that is updateable to the routing table for the node disposed behind the mobile terminal, employing the gateway node to send the other new route along with the Update session profile message to the serving node where they are employed to update the serving node and the mobile terminal with the other new route.
