Modeling and Analysis of Zone-Based Registration in Mobile Communication Network by Considering Busy-Line Effect and Implicit Registration

Abstract

In this study, we consider zone-based registration (ZBR) in mobile communication networks. In ZBR, when a mobile moves to a new zone, it registers its zone to the network database to keep the mobile’s current zone, and to connect an incoming call to the mobile when it is generated. A mobile can store one zone, or more than one zones. Among various types of ZBR, we focus on two-zone-based registration (TZR), which is known to have good performance. In TZR, a mobile can store two zones that it has recently registered, and does not register when it crosses either zone that it has already kept. In general, in TZR, a mobile registers its zone less often than in single-zone-based registration (SZR). However, TZR increases the paging cost, because the network may not know the exact zone where the mobile is. Mathematical modeling and performance analysis are performed to obtain the exact performance of SZR and TZR, by considering the busy-line effect and implicit registration effect of outgoing calls from a mobile. From numerical results for various circumstances, it is shown that TZR is superior to SZR in most cases.

“…Many studies have been published on various location registration schemes, and there have been studies on distancebased registration [3,4], movement-based registration [3,[5][6][7], time-based registration, and so on [8,9]. However, most studies on mobility management have considered or included zone-based registration (ZBR) [10][11][12][13][14][15][16] because it is widely adopted by most mobile cellular networks. Even though ZBR is a classical approach, it shows good performance and can be easily implemented in 4G networks [17][18][19].…”
