System and method for testing protocol consistency for base station

Abstract

The invention provides a system and a method for executing protocol consistency test to a base station, wherein the system tests the base station in a world interoperable microwave access system based on TTCN-3 to ensure the consistency of a protocol entity realized by the test and the standard regulation regulated by the protocol. The invention adopts a structure constructed by a test background and a foreground proxy to test the base station, including: the test background used for analyzing and executing a coded TTCN-3 test use case and judging the test result, and the foreground proxy used for receiving and sending business data according to the requirements of the test background and sending control information to the base station. The invention realizes the protocol consistency test on the base station without the realization of physical layers such as a radio frequency module, and reduces the cost of the test system and improves the self-reliability of the test system, thereby achieving the purpose of saving cost and increasing the robustness of the test system.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a TTCN-3-based system and method for performing protocol consistency testing on base stations in a WIMAX system. Background technique [0002] TTCN-3 (Testing and Test Control Notation Version 3, the third edition of Test and Test Control Notation) is an internationally standardized test script language developed by ETSI (The European Telecommunications Standards Institute, European Telecommunications Standards Institute), and Published as ETSI ES 201 873 series standard documents, as a powerful black box test standard based on response system, TTCN-3 is widely used in many different fields and types of tests, especially in the field of communication protocol consistency It plays an unparalleled role in Protocol Conformance Testing (PCT, Protocol Conformance Testing). [0003] WiMAX technology (Worldwide Interoperability for Microwave Access) is a broadband wireless access ...

AI Technical Summary

Problems solved by technology

There are two disadvantages in this test system: First, the simulation of mobile terminals requires the support of complex software and hardware to realize the functions of baseband and radio frequency. It is difficult to be accepted by BS manufacturers; secondly, the protocol conformance test is mainly aimed at the MAC (Medium Access Control, Media Access Control) layer of the WIMAX system, and the introduction of the physical layer implementation not only increases the cost of the test system, but also increases the The unreliability of the test system itself has also caused certain difficulties for the problems found in the positioning test
