In the near future Personal Communication Networks(PCN), any personal subscriber can make calls to whomever from anywhere at any time. These personal communication networks are characterized by several features, such as high user population density, high mobility and enhanced supplemented services. The significant amount of signaling traffic is generated due to the mobility problems including location registration/updating and hand-over, compared with that of conventional wired network.
In this paper, we model the mobility of personal subscribers related to the location registration/updating and then analyze its required signaling traffic based on the Global System for Mobile(GSM) standard in the given PCN configuration. We find the optimal location area by minimizing the signaling traffic of both location registration/updating and paging, and we discuss the possible network configuration.
