Abstract


With the rapid development of3G mobile networks, the construction of3G base stations is urgently needed. For telecom operators, the difficulty of3G base station sitting has been far greater than the construction of2G. How to take advantage of the huge site of the GSM base stations to expand its3G capacity, has been one of the major problems for the operators.MSR (Multi standard radio) which came into being is a very good solution for operators, which makes full use of the existing2G base station resources and can make substantial cost savings. MSR technology makes operators easily increase capacity by changing very small hardware, and can easily achieve dynamic power sharing, and they can help operators to achieve a smooth transition from2G to3G, even to4G.MSR application software is developed on the Vxworks, it’s based on Alcatel-Lucent’s internal software package. The software contains two main modules SCP&CPRI and12key interfaces. The MSR alarm module is developed in JAVA, using J2EE system architecture.Firstly, this thesis has a general introduction of MSR system design, hardware and software structure, then give a detailed description for each module’s function and design principle, and2G&3G switching process. Finally, we illustrate how to achieve the function of the MSR.
