Abstract
A reachability service is provided to connect portable nodes of a moving network to at least one external, fixed network via at least one mobile router. Temporary name identifiers are allocated to the portable nodes and mapped to current reachable addresses of the portable nodes by at least one proxy name server.
Claims11
A method of operating a mobile vehicular network for providing a reachability service to connect portable nodes of the mobile vehicular network to at least one external fixed network via at least one mobile router, comprising:
- registering a group of temporary name identifiers on behalf of several portable nodes attached to the mobile vehicular network by the mobile router;
- allocating the temporary name identifiers to the portable nodes;
- mapping the temporary name identifiers to current reachable addresses of the portable nodes by at least one proxy name server;
- updating the at least one proxy name server by mobile routers of the mobile vehicular network cooperatively sending registration and mobility update messages with recent address information of the portable nodes in response to any address change to ensure that sufficient information to resolve naming requests is available in the at least one proxy name server;
- and
- providing, by the mobile router, the at least one proxy name server with an address to forward a name resolving request to a local name server in case the proxy name server is unable to resolve a naming request.
A method for operating a mobile network for providing a reachability service to connect portable nodes of the mobile network to at least one external fixed network via a mobile router configuration, comprising:
- allocating temporary name identifiers to the portable nodes;
- mapping the temporary name identifiers to current reachable addresses of the portable nodes by at least one proxy name server;
- updating, using multiple mobile routers, the at least one proxy server using registration and mobility update data including recent address information associated with the portable nodes in response to any address change, and
- wherein at least one mobile router is movable into a range of the at least one external fixed network.
A mobile vehicular network configuration having access to at least one external network, comprising:
- a plurality of portable nodes connected to the mobile vehicular network via a plurality of mobile routers, the plurality of mobile routers:
- providing access to the at least one external network by the portable nodes,
- registering a group of temporary name identifiers on behalf of the plurality of portable nodes, and
- allocating the temporary name identifiers to the portable nodes;
- and
- a proxy name server mapping the temporary name identifiers to current reachable addresses of the portable nodes,
- wherein the plurality of mobile routers update the at least one proxy name server via registration and mobility update messages which include recent address information of the portable nodes in response to any address change to ensure that sufficient information to resolve naming requests is available to the at least one proxy name server, and
- the at least one proxy server is provided with an address to forward a name resolving request to a local name server in case the proxy name server is unable to resolve a naming request.
