Performance Evaluation of Location Management Techniques in PCS Network
Location management being a major part of cellular network provides mobility to mobile subscribers. The current location information is required to route the call correctly to the recipient irrespective of its current location. The current HLR/VLR architecture for location management in standards like IS-41 & GSM suffers from call setup delay due to network congestion and also prone to failure ...
متن کاملModified 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 کاملPerformance Analysis of Existing Location Management Scheme with its Variants in PCS Network
This paper is presenting a comparative study of existing location management scheme with its various variants in Personal Communication Services (PCS) network. The existing location management scheme is based on two tier database architecture; Home Location Register (HLR) and Visitor Location Register (VLR).In the existing location management scheme, there is a single HLR. In the HLR, profile o...
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 ...
