The main aim of cellular mobile communication is to discover existing location of mobile terminals to distribute the service, which is well-known as location management. The LM involves tracking of (mobile terminal's) MT's up-to-date location, which moves freely across different cells in order to provide those services. Every MT undergoes same number of updates when passes through a specific region. One such scheme is reporting centre in which, some of the cells are designated as reporting centers and all close by cells up to the next reporting centre belong to vicinity of same reporting centre. MT updates its location whenever it crosses vicinity of its current reporting centre, which happens no more than when it enters into another reporting centre and therefore a LU is triggered.
