摘要：The deployment of the LTE is picking up pace in many countries and these networks are deployedalongside the existing 2G/3G services. LTE/LTE-A networks offer higher data rates and reduced delay tothe subscribers. Today's mobile networks consist of equipment from multiple vendors and they are calledmultiple vendor networks. Interoperability testing is important at initial network launch and duringnetwork expansion. This paper discusses a typical problem related to interoperability testing along with thetest results and the issues faced during the testing. The test results discussed in the paper are obtained fromthree scenarios - before testing, during testing and after testing. The test results are used to study theimpact on network performance. Apart from the interoperability testing, an outline of testing that focus ongeneral network stability, the interworking capability of LTE with other technologies such as 2G and 3Gand taxonomy for the generation of key performance indicators (KPIs) are also discussed.
