The call performance for body-centered-cubic cell and cubic cell in 3-dimensional personal communication system

With the appearance of the microcell and in-building systems, the cellular mobile networks and the personal communication systems (PCS) have been established in the three-dimensional space. A traffic model and analysis for both the cubic and proposed body-centered-cubic (BCC) cells with handoff are examined. The blocking probability and the handoff attempt failure probability are derived and presented. In this study, three schemes for call traffic handling are considered. One is nonprioritized and two are priority oriented. Fixed channel assignment is considered. In the nonprioritized scheme, the base stations make no distinction between new call attempts and handoff attempts. Attempts which find all channels occupied are cleared. In the two priority schemes, a fixed number of channels in each cell are reserved exclusively for handoff calls. Appropriate analytical models and criteria are developed and used to derive the performance characteristics.
