Abstract

In this paper, we propose a new visitor location register (VLR) failure recovery scheme called demand re-registration for personal communications services (PCS). In this scheme, the VLR broadcasts a re-registration request to all mobile stations (MSs) after the VLR failure. When an MS receives the re-registration request, it sends a registration message to the VLR to recover the location record. We study the performance of demand re-registration by investigating how effectively the re-registration can recover the location record for an MS before the first MS call termination occurs. Our results indicate that demand re-registration can effectively recover from VLR failure
