Two stage HLR mechanism of mobility management in a PCS network
Hui Liu · Journal of China Institute of Communications · 2002
In this paper, we present a novel disposal method, two stage HLR, to deal with the mobility of roam user in a PCS network. Compared with IS-41, GSM and forwarding pointer system, the method can reduce long-distance registration and cancellation process signaling and escape long-distance waste allocation of net resources without higher demand for basic construction of service provider. The registration and cancellation cost can be reduced at full steam since the roam users information was put HLR抯 special memory. The method is feasible since memorys cost decreases gradually.
