With the rapid development and prevalence of 3G wireless networks, the 3G wireless communication service is used more and more widely. It makes the world more convenient, but at the same time, it brings unprecedented challenges to the wireless network operator and device manufacturer. Since the network scale and complexity grows rapidly, the tasks of network maintenance become more and more heavy. Network mirror is a normal operation mode for daily network maintenance. Tests and experiments are made in mirror networks, to reproduce network errors and find out the solution. This article proposes a method for building mirror networks rapidly, to help maintainers for solving network problems.Firstly, this article makes analyze for 3G wireless network structure, to build up a network configure object model based on UML. This model is used to describe the network configure precisely, including all information of wireless network parameters.Secondly, based on the analysis of network mirror requirement, this article proposes the policy-based method, to design and implement the network mirror system. Based on the IETF policy architecture, this article proposes the policy architecture for network mirror system; then, this article uses XML to define the mirror policy; this article also proposes the confliction detection algorithm for network mirror policy. The policy-based implementation method makes the system more flexible.Lastly, this article proposes the architecture of mirror system, to guild the implementation of the system.
