Modified HLR-VLR Location management scheme in PCS network
This paper proposes a modified version of conventional HLR/VLR scheme for improving the location management in PCS network. The conventional HLR/VLR scheme suggests that when a mobile terminal (MT) moves from one LA to another LA which is served by different VLR, it registers itself with new VLR along with HLR, at the same time HLR deregisters the mobile terminal from the old VLR and acknowledg...
متن کاملMulti HLR Architecture for Improving Location Management in PCS Network
This paper proposes a multi HLR scheme for location management in PCS network instead of having a single HLR. In conventional architecture we have a single HLR that acts as centralized database to store the user profile along with the MT’s location information. This approach of single HLR suffers from two major disadvantages: bottleneck and call misrouting during the peak load. In multi HLR arc...
متن کاملTolerating VLR and HLR Failures in Two-Tier PCS Networks
One of the key issues in the design of personal communication service (PCS) systems is the efficient management of location information. The current IS-41 and GSM schemes use a two-tier system of home location register (HLR) and visitor location register (VLR) databases. In a two-tier system, the success of a call requires the HLR and the callee’s current VLR to be failure-free. A VLR failure a...
متن کاملEvaluation of Distributed and Replicated HLR for Location Management in PCS Network
Personal Communication Service (PCS) network is the integration of cellular Network and conventional wired network. To support user mobility, the locations of the mobile stations (MSs) should be constantly tracked using a database. The widespread deployment of PCS will lead to a tremendous increase in the number of updates and queries to the location database. The centralized, stand-alone Home ...
متن کاملMobile Switch VLR 1 HLR VLR 2 Mobile User
Acknowledgement We would like to thank the the three anonymous reviewers for their valuable comments. Abstract In a cellular phone system, mobility databases called visitor location registers (VLRs) are used to temporarily hold the subscription information of the roaming users who visit the service area of the VLR. When the users leave the VLR area, the corresponding records in the VLR are dele...
