TLDR
A currently available standard for location management is described and research results on location management are surveyed in detail.Abstract:
Personal communications services (PCS) support mobile terminals (MTs) which are free to travel within the service coverage area. In order to effectively locate an MT when a called is initiated, location management schemes are used to keep track of the locations of the MTs. The current approach to location management requires each MT to report its location to the network periodically. The location information is then stored in databases. When a call is initiated. The network determines the current location of the called MT through a database lookup and paging procedure. A currently available standard for location management is described. Research results on location management are surveyed in detail.read more

Location estimation and trajectory prediction for cellular networks with mobile base stations
TL;DR: This paper proposes using a Robust Extended Kalman Filter to derive an estimate of the mobile user's next mobile base station from the user's location, heading, and altitude, to improve connection reliability and bandwidth efficiency of the underlying system.

Movement-based location update and selective paging for PCS networks
TL;DR: In this paper, the authors proposed a mobility tracking mechanism that combines a movement-based location update policy with a selective paging scheme, where each mobile terminal only keeps a counter of the number of cells visited and a location update is performed when this counter exceeds a predefined threshold value.

Mobile users: to update or not to update?
TL;DR: This paper considers both memoryless movement patterns and movements with Markovian memory along a topology of cells arranged as a ring and analyzes the performance of each one of the three strategies under such movements, and shows the performance differences between the strategies.

A caching strategy to reduce network impacts of PCS
TL;DR: 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.

Minimizing the average cost of paging under delay constraints
Christopher Rose,Roy D. Yates +1 more
TL;DR: It is shown that substantial reductions in E[L] can be had even after moderate constraints are imposed on acceptableD (i.e.,D<-3), and this work should be applicable to a wide range of problems in the area.

Dynamic location area management and performance analysis
TL;DR: In this paper, a dynamic location area scheme is proposed for cellular networks, in which the size of location areas of a user is dynamically determined according to its current incoming call arrival rate and mobility as the signaling traffic in radio channels reaches the minimum.
