A Modified Multi-HLR Architecture for Implicit De-registration Strategies
Sarvpal H. Singh, Vijay Kumar · International Journal of Computer Applications · 2012
This study proposes a modification in the de-registration policy of Multi-HLR architecture.This architecture has made an attempt to overcome the drawbacks of Single centralized HLR architecture by introducing multiple HLRs in PCS networks in performing location managements of mobile units using explicit de-registration policy.This paper presents a modification in the de-registration policy of Multi-HLR architecture by applying the concept of implicit deregistration strategies and gives a performance analysis of this modified architecture to show how these implicit deregistration policies outperform the explicit de-registration strategy.
