A personal communications network (PCN) location tracking scheme called local anchoring is introduced which reduces the signalling cost as compared to the location management strategy proposed in the IS-41 standard. Local anchoring reduces the number of location registration messages between the home location register (HLR) and the visitor location registers (VLRs) in a way that location change is reported to a nearby VLR called the local anchor (LA) instead of to the HLR. This method…

TLDR
A novel location management scheme which intends to mitigate the signaling traffic as well as reduces the connection setup delay in the PCS networks and can significantly reduce the network signaling traffic for users without increasing much of the call setup delay.
Group-Based Location Management Scheme in Personal Communication Networks
TLDR
A new location management strategy which is based on the centralized database architecture with HLR/VLR concept is proposed to reduce the number of location registrations by grouping MTs (Mobile Terminals) with a similar velocity and the same moving direction.
A pointer forwarding based local anchoring (POFLA) scheme for wireless networks
TLDR
A novel location management scheme, pointer forwarding based local anchoring scheme, that intends to mitigate the signaling traffic while keeping the tracking delay in check and the numerical results show that this scheme can significantly reduce the network signaling traffic load without increasing much of the call setup delay.

TLDR
It is revealed that compared to the conventional RA-based location registration scheme, the group registration strategy can achieve a significant cost savings over a wide range of system parameters.
Group registration with local anchor for location tracking in mobile networks
TLDR
This work proposes a new location registration strategy, called Group Registration (GR), which efficiently reduces the location registration cost by reporting location changes to the HLR for multiple mobile terminals (MTs) in a single location update request message.
An integrated strategy for reducing location management cost
TLDR
An integrated location information management strategy is proposed for mobile networks, where local anchor and replica are deployed to efficiently manage the location information of a mobile terminal based on its call and mobility characteristics to reduce location tracking costs.
A Delayed Location Registration Procedure for Wireless Mobile Communication Networks
TLDR
This paper proposes a new location management scheme that is to reduce the number of location registrations at HLR by making the location registration at H LR unnecessary when an MT moves into neighboring registration area (RA) or when it moves back to the original RA from neighboring RA.

TLDR
The results show that the proposed strategy outperforms the other three strategies over a wide range of system parameters.
Location Management with Dynamic Anchor Scheme in Wireless ATM Networks
TLDR
A dynamic anchor scheme in wireless ATM (asynchronous transfer mode) networks, which improves the location registers (LR) scheme, in which LR’s are hierarchically structured, and reduces computation cost by introducing the active LR.
Two-Level Pointer Forwarding Strategy for Location Management in PCS Networks
TLDR
A new location management scheme is presented which intends to mitigate the signaling traffic as well as reduce the tracking delay in the PCS systems and can significantly reduce the network signaling traffic for users with low CMR without increasing much of the call setup delay.

A forwarding strategy to reduce network impacts of PCS

TLDR
An auxiliary strategy for locating users who move from place to place while using Personal Communications Services (PCS), called per-user caching, is proposed, which attempts to exploit the spatial and temporal locality in calls received by users, similar to the idea of exploiting locality of file access in computer systems.
