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.

Abstract: A method of dynamically allocating bandwidth of channels to cells in a communications cellular network according to user demand. Disjoint groups of cells are formed so as to minimize interference within each group, and a particular channel is assigned to each of the groups. The bandwidth of each channel then dynamically allocated by time division to each of the cells in a group according to user demand in each of the cells.
