Abstract—RRC (Radio Resource Control) protocol belongs to the LTE protocol stack and handles the control plane signaling of Layer 3 between the User Equipment and E-UTRAN. The specifications of RRC conformance testing are released by 3GPP in the 36-series documents. RRC test suites are normally developed by use of the testing language TTCN-3 which has the characteristics of platform independence and abstract description. As a key component in testing architecture, the adapter propagates the request and reply operations between tester and SUT (System under Test). In order to fulfill data transmission within a limited time according to the corresponding protocol, developers have to complete a complicated configuration of adapter. This paper focuses on the design of the adapter. First it analyzes the main framework of test system and constructs the concrete structure. Then the mechanism and workflow are illustrated. Finally, we elaborate how the adapter can achieve better performance to acquire accurate timing control and to implement multi-protocol communications.

Index Terms—Adapter, LTE, protocol conformance test, RRC, TTCN-3, TRI.
