Reducing the cost of dynamic mobility management in wireless communication networks has been an interesting and important issue. It is well known that by using a selective paging method, both costs for location update and terminal paging can be reduced significantly. However, an efficient selective paging method needs the information of the location distribution of a mobile terminal. Based on o...

We formulate the optimum personal paging area problem as an interval estimation problem, with an aim to reduce the paging signaling cost by minimizing the size of the paging area. A paging algorithm is developed to set-up the optimal one-step paging area that contains the locations of a mobile user with a high probability and thus to gain a coverage that is matched to the user’s time-varying mo...

We present some results regarding the paging cost gains and the cost-delay tradeoff that can be achieved by using sequential paging to locate mobile users in cellular networks. We describe tight bounds on the average paging cost and the paging delay and quantify the intuition that greater gains are achieved when the mobile user’s location probabilities are concentrated in a small portion of the...

In long-term evolution, the service area is partitioned into several tracking areas (TAs), which comprise one or more cells (the radio coverages of base stations). The TAs are grouped into TA list (TAL). When an incoming call arrives, the network attempts to connect to the user equipment (UE) by paging the cells in the UE’s TAL, which may incur large paging traffic that significantly consumes t...

We consider the problem of minimizing the paging cost subject to the delay constraint in Personal Communication Services Network (PCSN). Here, we present two intelligent paging strategies for third generation PCSN. They are termed as sequential intelligent paging (SIP) and parallel-o-sequential intelligent paging (PSIP). Both are intelligent in the sense that cell(s) to be paged in a cycle are ...

The paper introduces a new paging technique to track and wake up a mobile node attached to an access point in wireless LAN network after a SIP INVITE message is initiated by a caller. Tracking Agent keeps track of the mobiles’ handoffs between the access points. Paging Agent triggers tracking agent to page the mobile when a SIP INVITE is received for one of its users. Context transfer feature o...

| We consider the problem of minimizing average paging cost subject to delay constraints in a wireless system. Previous work assumed the unit to be found did not move during the paging process whereas here the unit may change location during polling events. We show that the conditionally most probable locations given that the unit has not yet been found should be searched rst. We nd the optimal...

In a high-capacity cellular network with limited spectral resources, it is desirable to minimize the radio bandwidth costs associated with paging when locating mobile users. Sequential paging, in which cells in the coverage area are partitioned into groups and paged in a non-increasing order of user location probabilities, permits a reduction in the average radio costs of paging at the expense ...

In this paper new paging schemes are presented for locating mobile users in wireless networks. Paging costs and delay bounds are considered since the paging cost is associated with bandwidth utilization and delay bounds influence call setup time. In general, location tracking schemes require intensive computation to search for a mobile terminal in current PCS networks. To reduce the paging cost...
