RADIOTELEPHONE SERVICE PLANNING SYSTEM AND METHOD FOR DETERMINING A BEST SERVER FOR A COMMUNICATION CONNECTION

摘要

A radiotelephone service planning system (10) and method determines best servers in communication systems by determining an interference based communication threshold using interference information (46), such as frame error rate data, in addition to pathloss information (38) between a communication unit (22) and the plurality of other communication units (24a24c). The radiotelephone service planning system (10) and method generates an image indicating the most probable best server of the other communication units (24a-24c) for the communication unit (22) based on the interference based communication threshold information. Also, the system utilizes variable signal threshold data (32) for a communication unit to allow flexibility in determining a best server site in view of varying threshold limits. If desired, the system can also accommodate three-dimensional best server planning by taking into account elevational variations and their effects from the perspective of both the mobile communication unit and the other communication unit.
