Abstract :
A new hierarchical location registration is presented for personal communications, and its related call routing through broadband-ISDN is described. The call routing utilizes signaling packets to directly access the lowest registration unit (HLRUO) of portable stations, so that centralized accesses as in GSM systems are avoided. After a description of the model of hierarchical location registration, the average number of registrations at each layer is statistically analyzed. The registration time interval vs. roaming range is derived. Thus, the average time interval for updating location information in the HLRUO is obtained. The performance evaluation of the proposed scheme and a comparison with GSM are outlined
