| 總結: | Wireless personal communication networks (PCNs) consist of a fixed wireless network
with nodes providing wireless coverage area and a large number of mobile terminals
(MTs). These terminals are free to travel within the PCN coverage area without service
interruption. Each terminal periodically reports its location to the network by a process
called location update. When a call arrives for a particular mobile terminal, the network
will determine the exact location of the destination terminal by a process called terminal
paging. There are many schemes proposed which aim at reducing signaling costs and all
these schemes were based on different assumptions and network parameters. Our
objective is to study the updating and paging process of the MTs under different
dynamic location management schemes, and to develop an adaptive scheme that caters
for the ever-changing network parameters. In this thesis, a dynamic paging scheme is proposed and presented based on the semi-real time velocity information of an
individual mobile user. This allows for more accurate prediction of the user location
when a call arrives and therefore, reducing the cost of paging. The scheme is based on a
basic scheme that was proposed in the open literature. Our new scheme results show that
the newly proposed adaptive movement threshold and the adaptive velocity time unit
schemes provide significant costs savings, compared to a benchmark system and the
basic scheme, under different cell radius sizes and MT velocities broadly classified as
high and low mobility systems. |
