“…We have observed that in most of the prior schemes, specially proposed in [6,10,11,12,13,14,15,16] CMR plays big role in selecting a particular location management scheme. If CMR value of called mobile user is higher, forwarding pointer schemes are selected otherwise replication schemes are selected.…”

“…Since performing remote queries can be slow due to high network latency, therefore current PCS systems usually improve the lookup to HLR by maintaining location profile of called user B at current VLR of caller A. There are several enhancements of basic two-tier schemes like per mobile node based location profile caching/replication [6,8,9,10,11], forwarding pointer schemes [12,13,14], and hybrid scheme [15]. But there is no interrelationship among the replicated sites proposed in the prior schemes.…”

-Replication strategy is mostly useful for replicating the called mobile user's profile at selected locations where some caller mobile users have higher calling rate. It plays important role in personal communication services (PCS) in order to reduce call setup cost and call setup time. In prior replication schemes, replicated sites (visitor location registers) have no inter relationship. We have proposed a novel and innovative replication tree which is buildup from replicated VLRs (visitor location registers). VLRs are replicated based on effective replication probability of caller mobile user. Home location register (HLR) keeps update replica at root VLR in the replication tree and root VLR forwards update replica to a VLR in the replication tree on demand. The main objective of the proposed scheme is to reduce call setup time and call setup cost by enabling replication of called mobile user's location profile at certain visitor location registers (VLRs) where caller mobile user roams. We have presented analytical modeling which shows that setting inter-relationship among the replicated sites helps in further reducing the call setup cost.

“…The key idea of location forwarding is that instead of updating the location database located far away from the mobile user, the reporting in location change can be reduced by simply setting up a forwarding pointer from the old pointof-attachment to the new one [9]. Various variations related to location forwarding in wireless cellular networks have been reported in [10,11,12]. In [10], a hierarchical version of location forwarding was proposed, in which a two-level mobility management was introduced by selecting a set of VLRs as mobility agents (MAs) responsible for location management in geographically larger area compared with the VLR coverage.…”

Abstract. Location management is one of the most challenging issues in future wireless mobile networks. In this paper, from the viewpoint of fundamental principles underlying location management schemes regardless of network types, we review and analyze a variety of existing location management schemes which have been reported for wireless cellular networks and Mobile IP-based networks, and derive common key conceptual ideas, their main design goals and common performance considerations on them, which can provide a useful guidance for understanding location management schemes regardless of network types. The goal of this paper is not to propose a new location management scheme, but to highlight various key design features involved in the existing location management schemes and enhance an insight into the common underlying principles and techniques for designing more efficient and optimized location management scheme in future wireless mobile networks.

“…Recent advancements in location management schemes focus on per-user-based scheme in which location update and searching of MUs can be adapted dynamically based on MU's calling and mobility patterns. For example, when the frequency of incoming calls is higher than the mobility rate of the MU (CMR value is high), the caching/replication scheme [10][11][12][13] is effective; but when CMR is low, the forwarding pointer schemes as proposed in [1,[14][15][16], and local anchoring scheme [14] are effective. Hybrid schemes have been proposed in [17,18], which combine the merits of forwarding pointer and replication.…”

In urban cities, many MUs (mobile users) follow a fixed mobility pattern. Most of the time, these users can be found in a particular registration area (RA) at a certain time period. We say that MUs follow a fixed set of RAs on a daily basis. Therefore, an MU can be located at one of the RA from the set of fixed RAs when a call arrives. In prior schemes, the location update cost is minimized by increasing paging cost. In this paper, we propose a mobility agent (MA) and adaptive paging strategy based on MUs' movement. The MA is a special functional entity in the network, and many RAs are connected to MA as per mobility pattern of an MU. The paging area is selected based on the average speed of MUs. The major features of the proposed scheme are the overall reduced location management cost and less paging time compared with existing scheme. We present analytical modeling and performance evaluation that show that the proposed scheme has less location management cost and less paging time to locate an MU compared with existing scheme.
