In order to decrease the consumption of the limited bandwidth resource and the electronic power of mobile battery, fixed paging area strategy is adopted in most mobile communication networks currently. Although its application is very simple, it cannot reach the best performance. In allusion to this problem, we introduce four kinds of improved mobile paging strategies, and analyze their concrete implementation methods briefly. Their performances are compared with fixed paging area strategy. Moreover, the benefits,the drawbacks and the range of application of each scheme are pointed out for future study.
