文中首先介绍了WCDMA Iur接口的基本原则,然后描述了Iur接口在实现过程中存在的业务类型识别问题,并且分别介绍了在源RNC和漂移RNC中业务类型识别的方法,其中,重点介绍了用于漂移RNC的一种最大速率和特征值匹配的业务类型识别技术,这种技术极大地提高了Iur接口的开放性,为不同厂商的RNC的互联提供了基础。
In this paper, the basic principle of WCDMA Iur interface is introduced first, then the problem of service type identification in Iur interface is described, and the methods of service type identification in source RNC and drift RNC are introduced respectively, A type of traffic identification technique that matches the maximum rate and eigenvalue of a drift RNC. This technique greatly improves the openness of the Iur interface and provides the basis for interconnecting RNCs from different vendors.
