Umts System, The Rnc Iub Test System Implementation

With the rapid development of the mobility communication technology, the computer technology, the network technology and the electronic technology, the world is stepping into 3rd generation era. The 3rd generation mobility communication system is the outcome made by the integration of mobility communication, computer, network and electronic, and it will result in the revolutionary change of human's lifeway. The structure of 3G system is very complicated, and it has a great number of protocols among those devices in 3G system. It is a very important issue how to test these devices with high efficiency and obtaining high performance products, so testing those devices in 3G system is a technical domain being worthy of devotion.In this paper, we introduced a system used to testing Iub protocol of Radio Network Controller in UMTS, the hardware and software structure was described. My work in this project is to design ATM driver bearing Iub protocol and flash dirver, the implementation of those drivers was introduced in this paper, and the feasible resolvent for the issues met in this project was brought.
