LTE Radio Resource Management Conformance Testing: Exploration and Implementation

—LTE is an evolution of 3G technology which possesses 100Mb/s data downloading capability. The technology of LTE is progressive and puts forward stricter requirements for terminals. All the LTE wireless terminals must pass the Radio resource Management (RRM) conformance testing before entering into the market. This paper first dissected TTCN-3 test system and RRM testing structure for the purpose of designing RRM testing model. The testing model proposed in this paper realized the equal data exchange between test system (TS) and system under test (SUT) in application layer, and thus solved a big problem in constructing test platform of RRM testcases. Then comes the most difficult tasks: develop RRM testcases, system adapter (SA) and codec (CD). Among the tasks, RRM testcases are developed based on the test suite released by European Telecommunication Standards Institute (ETSI). Important runtime testing processes including Authentication and Key Agreement (AKA) process, preamble transfer process and cell reselection process are dissected in detail for the purpose of programming. SA is developed according to TRI specification using socket programming. CD is developed according to TCI specification.. On the basis of massive practical work, the implementation of RRM conformance testing is shown.
