System load estimation for IMT-2000 in multi-user multi-service environment

Abstract

The IMT-2000 system provides diversified functionalities as compared with the existing mobile phone systems. Through considerable enhancements in lower layer, multistage multiplexing, and common channel accessing, simultaneous multiple services for multiple users can be supported. Traffic patterns generated by users vary, consuming system resources in different ways. To economically design a wireless network, a new system load estimation method has to be developed, the resulting value of which may be used as one of the most important decision criteria. In this paper, we propose a new method to calculate a system load, especially the wireless channel load, in multi-user multi-service environment, based on which key system design criteria are presented.
