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 first. We find the opt...

In this paper new paging schemes are introduced to reduce paging costs under delay bounds. In general , location tracking schemes require intensive computation to search for a mobile terminal in current PCS networks. Three new paging schemes, reverse, semi-reverse and uniform, provide a simple way of partitioning the service areas and accordingly minimize the paging costs based on each mobile t...

Dynamic location management for a mobile terminal is a key problem in wireless communication networks. There are three fundamental performance and cost issues in terminal paging. The first issue is the speed (i.e., time delay) of terminal paging. The second issue is the cost (i.e., the number of cells paged) of terminal paging. The third issue is the quality of service (QoS), i.e., the probabil...

This paper introduces a dynamic paging scheme based on the semi-realtime movement information of an individual user, which allows a more accurate predication of the user location at the time of paging. In general, a realtime location tracking scheme may require complex control schemes and incur unacceptably high computation and messaging cost. Our proposed approach, namely velocity paging schem...

In a telecommunications network locating user equipment (paging) is a common procedure. Proposed functionality for 4G and 5G allows for eNB initiated paging via X2 interfaces. In this thesis machine learning algorithms were evaluated in order to reduce page signalling. Additionally, two paging schemes based on machine learning were proposed and compared to a common method of paging through cost...

One of the remaining issues of Mobile IP is a mobile host (MH) needs to update its location each time it moves from one subnet to another, even when it is in dormant mode while roaming. This practice is apparently not efficient in terms of location update cost and power consumption. Recent research works have attempted to address that problem by extending Mobile IP with a layer 3 paging mechani...

Recently, IEEE 802.11 wireless networks have been widely deployed in public areas for mobile Internet services. In the public wireless LAN systems, paging function is necessary to support various advanced services (e.g. Voice over IP and message applications) and to provide efficient power management scheme. In next-generation mobile networks, the so-called all-IP networks, the paging function ...

Cellular telephones save power by switching to a low power, or dormant, mode when there is no active traffic. In dormant mode, the telephone periodically checks for a beacon, and if the beacon indicates that the phone has moved to a new paging area, the telephone performs a paging area update. Paging area update signaling requires considerably less power than is required to move an active traff...

We consider an optimum personal paging area configuration problem to improve the paging efficiency in PCS/cellular mobile networks. The approach is to setup the boundaries of a one-step paging area that contain the locations of a mobile user with a high probability and to adjust the boundaries to gain a coverage that is matched to the mobile user’s timevarying mobility pattern. We formulate the...

This paper addresses the requirement for a congestion control mechanism, in order to efficiently handle paging traffic over cellular networks. The standard simultaneous paging approach can easily result in congestion, for relatively small values of the offered load. Instead of differentiating paging capacity based on the incoming load, this approach is more oriented towards a limited-resource s...
