Systems and Methods for Improving Network Mobility
First Claim
1. A method of providing mobility between network subnets for a plurality of mobile network nodes attached to a mobile router, which mobile router hides any change in network subnet from said plurality of mobile network nodes and which network subnets provide access for said mobile router to a fixed network infrastructure, which method comprises the steps of:
- (a) providing a signaling channel for each of said plurality of mobile network nodes; and
(b) providing a data channel for each of said plurality of mobile network nodes;
characterized in that said signalling channel utilises a multicast communication protocol to perform a mobility function on behalf of one or more of said plurality of mobile network nodes.

24. A method of updating a SIP User Agent (UA) on a mobile network node, which method comprises the steps of:
-
transmitting an update to said mobile network node; and causing said mobile network node to install said update;
which update comprises;computer executable instructions for causing said mobile network node to join a multicast group in response to receipt of a SIP-like signalling message. - View Dependent Claims (27)

26. A network node (MR-SS) for managing a plurality of mobile network nodes attached to a mobile router, which network node comprises a memory storing computer executable instructions that when executed cause said network node to provide a signalling channel for said mobile network nodes by utilising a multicast communication protocol.
