A selective location update strategy for PCS users
A new location update strategy for personal communication services (PCS) networks and its implementation using a genetic algorithm are proposed. Most of the practical cellular mobile systems partition a geographical region into location areas (LAs) and users are made to update on entering a new LA. The main drawback of this scheme is that it does not consider the individual user mobility and ca...
متن کاملNew User Tracking Algorithms for a Wireless Network and Performance Analysis
| In cellular wireless networks, paging and user location update are used to deliver calls to mobile users. We propose two new user location update methods. One method which improves the movement based user location update scheme, exploits the locality of user movement patterns. Another method performs distance-based location update based on LA such that it simpliies implementation. To compare ...
متن کاملTradeoff analysis for location update and paging in wireless networks
Location management plays the central role in providing ubiquitous communications services in the future wireless mobile networks. Location update and paging are commonly used in tracking mobile users on the move, location update is to update a mobile user’s current location while the paging is used to locate a mobile user, both will incur signaling traffic in the wireless networks. The more fr...
متن کاملAnalytical Results for Optimal Choice of Location Update Interval for Mobility Database Failure Restoration in PCS Networks
ÐWhen the location information for a mobile user in the Home Location Register (HLR) is corrupted or obsolete, the new arriving calls to the user may be lost. In order to minimize the effect of such HLR mobility database failure, a location update scheme called period location updating is proposed, and the cost analysis is performed. Analytical results for the failure recovery time distribution...
متن کاملA New Location Management Strategy Based on User Mobility Pattern for Wireless Networks
For a wireless network to effectively deliver services to the mobile users, it must have an efficient way to track them. The location management fulfills this task through location registration and paging. Many location management strategies, such as profile-based scheme (PBS), have been proposed to reduce the signaling traffic caused by the location update and paging. In the PBS scheme, the sy...
