Abstract: PURPOSE: A tunnel-based handover system reducing tunnel length by grouping routers to decrease traffic load is provided to perform a binding update process by a specific access router if predetermined access routers change, and to be substituted for a role of an anchor access router, thereby limiting tunnel length. CONSTITUTION: A CN(Correspondent Node)(210) communicates with an MN(Mobile Node)(220). The MN(220) communicates with the CN(210). An aAR(anchor Access Router)(230) plays a current anchor role. nARs(Access Routers)(241-1,242-1,243-1) hand over an anchor role of a tunnel to one of the nARs(241-1,242-1,243-1) when the nARs(241-1,242-1,243-1) change as many as predetermined numbers by counting changed frequency of the nARs(241-1,242-1,243-1). An access router group(240) unifies the nARs(241-1,242-1,243-1) having link connectivity for the MN(220) at a certain point in one unit.

Abstract: PURPOSE: A mobility managing system and method for providing a micro-mobility service in an Internet protocol network are provided to simplify implementation of management by using a hierarchical base station and gate way, reduce an implementation cost, reduce a load caused due to a control message on a local network by having a simple control message, and not to apply a load to an Internet backbone network by terminating the control message in the gate way when traveling within a local network. CONSTITUTION: When a mobile host is advanced into a new domain, the mobile node recognizes that it has been advanced into a new service area and transmits a location registration message to a base station. Upon receiving the location registration message, the base station transmits the location registration message to its upper base station, which is continuously performed until the location registration message is reached to a gate way(110). Upon receiving the location registration message, the gate way(110) records an ID and location of the mobile host in its database(111) to thereby finish location registration of the mobile host. In case that the mobile host receives a packet through the Internet(112), the gateway(110) adds an additional header of N-1 bit indicating the location information to a packet and transmits it to a base station of a layer 1 (121). The base station of the layer 1(121) switches and transmits the packet to a base station of a layer 2(122) by using the most significant bit(N-1th bit). The base station(122) switches the packet and transmits it to a base station of the next layer, which is repeatedly performed to transmit the packet to the final layer(12N). When the mobile host is moved and its base station is changed, the mobile host discriminates information of the base station in a beacon broadcast from a new base station to thereby recognize itself being in a new base station area. The base station in service for the mobile host transmits a location update message to its own upper base station, which is continuously performed until the location update message is reached to the gate way(110).

Abstract: PURPOSE: A digital phase aligner with regard to metastability is provided which selects a clock pulse having a shift at the center of an input data bit in order to make an optimum composite clock for stably retiming a high rate binary data bit in which alignment jitter exists.
