Problems solved by technology

[0015] The shortcoming of the method for conformance testing of the TETRA air interface protocol in the above-mentioned prior art is: the method simulates a mobile terminal to test the TETRA protocol stack instead of testing with a real mobile terminal, which cannot test different The protocol test under the mobile terminal of the manufacturer, the TETRA protocol test conducted in this way is not true and perfect, and the actual response status of many mobile terminals is artificial
[0016] This test method is similar to a single-step debugging process, which is difficult to implement, cannot realize fully automated processing, and cannot perform independent parallel tests on multiple measured objects, which consumes manpower and time, and has low work efficiency.

Embodiment 1

[0038] In the test process of the embodiment of the present invention, the method of using software to simulate the mobile terminal is abandoned, but the test system is directly connected to the mobile terminal, and the AT command is used to control the mobile terminal according to the IOP (Inter- OPerability, interoperability) test plan for testing.

[0039] The signaling of the air interface interacted between the mobile terminal and SwMI (Switching and Management Infrastructure, switching and management infrastructure) is obtained through the protocol analyzer, so as to obtain the test data.

[0040] A kind of protocol test system based on TTCN-3 that this embodiment provides is based on the TTCN-3 test language to carry out protocol analysis to the system under test such as TETRA digital trunking system, detects the standard of the protocol implementation and protocol specification of each module in the system under test The regulations are consistent.

test Embodiment 18

[0046] Abstract test case 18 is used to write the TTCN-3 test script corresponding to the test case according to the requirements of the test case in the test plan. The TTCN-3 test script includes AT commands, which can control the mobile terminal and make the mobile terminal dial , answering and other business operations. In this way, the automatic execution of the test steps can be realized, and the work efficiency and the accuracy of the operation can be improved. There may be multiple TTCN-3 test scripts, and each TTCN-3 test script can control one or more mobile terminals at the same time according to the protocol requirements, and is used to perform test tasks on each mobile terminal. On the basis of using the TTCN-3 language, an intuitive and rich parallel TTCN-3 test script is written according to the requirements of testing multiple tested objects at the same time. Each PTC uses the TTCN-3 test execution machine to load and execute the above parallel TTCN-3 test scri...

Embodiment 2

[0057] Taking the system under test as an example of a TETRA system, this embodiment provides a processing flow of a TTCN-3-based protocol testing method such as image 3 As shown, including the following processing procedures:

[0058] The abstract test case in the test platform writes the TTCN-3 test script corresponding to the test case according to the requirements of the test case in the test plan. The TTCN-3 test script includes AT commands, which can control the mobile terminal and make the mobile terminal dial , answering and other business operations. There may be multiple TTCN-3 test scripts, and each TTCN-3 test script may correspond to one or more mobile terminals according to the protocol, and is used to perform test tasks on each mobile terminal.

[0059] According to the test case requirements, the test platform is connected to each mobile terminal, and the terminal port number and mobile terminal brand are configured.

Abstract

The embodiments of the invention provide a TETRA digit cluster protocol test method and system based on TTCN-3. The method mainly comprises the following steps: arranging a detected system comprising multiple mobile terminals and exchange and management basic facilities, the multiple mobile terminals being connected with a test system through PET interfaces; writing and executing a TTCN-3 test script corresponding to a test case through the test system, the test system using an AT instruction to control the mobile terminals to carry out service operation, monitoring the signaling interaction of the air interfaces between the mobile terminals and the exchange and management basic facilities, and performing matching comparison between the monitored signalings of the air interfaces and a TTCN-3-based standard signaling template stored in advance so as to verify whether the signalings of the air interfaces match protocol standards. According to the invention, a method of simulating mobile terminals by use of software is abandoned, the test system is directly connected with the mobile terminals, and the AT instruction is utilized for controlling the mobile terminals to carry out testing according to a TTCN-3 test script through a PEI. Since real mobile terminals are utilized, the test authenticity is improved.

Description

technical field [0001] The invention relates to the technical field of protocol testing, in particular to a TTCN-3-based TETRA digital trunking protocol testing method and system. Background technique [0002] Since the 1990s, the computer network represented by the Internet has developed rapidly. Since the computer network is a complex system, in order to exchange data in an orderly manner in the computer network, some pre-agreed rules, standards or conventions must be followed. These rules, standards or conventions clearly stipulate the format of the exchanged data. and related synchronization issues. These rules, standards or conventions established for data exchange in the network are called network protocols. A network protocol mainly consists of the following three elements: [0003] (1) Syntax, that is, the structure or format of data and control information; [0004] (2) Semantics, that is, what kind of control information needs to be sent, what kind of action to...
