Abstract: A communications network having a number of routers, a number of base stations and a number of mobile units maintains communications with the mobile units by assigning a unique address known to the routing entities of the network to each mobile unit. By including the mobile units unique address in topology updates of the network, the location of the mobile unit at any time is made known to all routers of the network. That is, once a mobile unit moves into a domain of a new access point and establishes a new link with the new access point, it uses the topology update mechanism of the network to make its new location known to all routers. Once a router of the network receives topology update information specific to the mobile unit's new location, it updates its routing table such that packets destined to the mobile unit are routed in a path which terminates at the mobile unit and contains its new access point.

Abstract: PROBLEM TO BE SOLVED: To provide a system for maintaining routing information based on a unique address to efficiently communicate when a moving object moves between domains.
SOLUTION: A communication network having a number of routers, a number of base stations and a number of moving objects allocates the unique address which is known by a routing entity of the network to each moving object to maintain a communication with the moving object. The unique address of the moving object is contained in topology updating of the network, such that all routers can know the location of the moving object anytime. Namely, the moving object moves into a domain of a new access point, establishes a new link with the new access point and then notifies all the routers of its new location using a topology updating mechanism of the network. Each of the routers of the network updates its routing table to be routed within a path including the new access point.

Abstract: A communications network (C100) having a number of routers (R101, R102), a number of base stations (B103, B104, B105) and a certain number of mobile units maintains communications with the mobile units by assigning a unique address known to the routing entities of the network (C100) to each mobile unit. By including the mobile units unique address in topology updates of the network, the location of the mobile unit at any time is made known to all routers (R101, R102) of the network. That is, once a mobile unit moves into a domain of a new access point and establishes a new link with the new access point, it uses the topology update mechanism of the network to make its new location known to all routers (R101, R102). Once a router (R101, R102) of the network receives topology update information specific to the mobile unit's new location, it updates its routing table such that packets destined to the mobile unit are routed in a path which terminates at the mobile unit and contains its new access point.
