Due to limited radio resource, an effective paging strategy is essential for improving the utility of radio channels. In current mobile communication networks, when a mobile-terminated call occurs, the network locates the mobile by paging all cells within the location area simultaneously. In this study, we introduces paging strategies that can page some cells or only one cell within the location area to reduce paging cost on radio channels using paging agents. We propose another new paging strategy that can page only one cell within the location area and may have better performance. We also compare the performance of our proposed paging strategy with the performance of the current simultaneous paging strategy and some new paging strategies using paging agents. This paper suggests the most effective paging strategy using mathematical models. The result of this research will be used to select a proper paging strategy in the mobile communication networks.

An effective paging strategy is essential for improving the utility of radio channels. This paper proposes a two-step paging strategy which involves using base station paging agents to page a single cell at each paging. An analytical model is used to evaluate the performance of the proposed strategy. The proposed strategy is compared with the traditional simultaneous paging strategy and a recent proposal using the base station paging agents. The numerical results showed that the proposed strategy proficiently reduces paging cost on radio channels compared with other paging strategies.

We propose a new paging strategy to reduce paging cost by adding paging agents at base stations. When a mobile-terminated call occurs, the base stations look up the paging agents to determine if terminal paging is actually to be made. An analytical model based on a Markov chain is used to evaluate the performance of the proposed strategy. The numerical results show that the proposed strategy significantly reduces the paging cost compared with the simultaneous paging strategy.
