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 control system for automated management of frequency-hopping in a radio network. The system includes a Wireless Network Manager (WNM) or Controller and a Wireless Control Agent (WCA), which control the distribution and maintenance of hopping patterns in the radio network. In a single cell network, the WNM and the WCA are included in a single base station. In a multiple cell network, the WNM is in a specific station on a LAN, and a WCA is located in each base station on the LAN. In each instance, the WNM is a centralized managing station and the WCA acts as a cell controller.
