Problems solved by technology

[0013] The shortcoming of the method of using the TTCN-3 test system in the above-mentioned prior art to test the TETRA terminal is: in the actual test, it is found that although ETSI has stipulated the specification of the AT command set of the TETRA terminal, in fact different manufacturers produce There are often differences in the AT command sets supported by TETRA terminals, so controlling different TETRA terminals to perform the same operation may require different commands to complete
Operators need to understand the various differences in the AT command sets supported by different TETRA terminals in order to perform correct operations on various TETRA terminals through different AT commands, which increases the complexity of testing TETRA terminals. This method relies on operator's manual

Embodiment 1

[0046] In the embodiment of the present invention, a port filter unit is set in the TRI in the TTCN-3 test system, and the AT command set supported by various TETRA terminals and the standard AT command set supported by the TE are stored in the port filter unit. The port filtering unit monitors and modifies the data transmitted between SA and TE, so as to eliminate the difference between TETRA terminals.

[0047] The embodiment provides a processing flow of a method for testing a TETRA terminal based on TTCN-3, such as figure 2 As shown, the following processing steps are included:

[0048] Step 21. Set up a port filtering unit in the TRI of the TTCN-3 test system, and store AT command sets supported by various types of TETRA terminals in the port filtering unit.

[0049] The differences between the AT command sets supported by TETRA terminals produced by different manufacturers mainly include the following situations:

[0050] (1) Differences in AT command parameter format...

Embodiment 2

[0064] The processing flow of a method for processing the AT command sent by the TE in the TTCN-3 test system to the TETRA terminal provided by this embodiment is as follows: image 3 As shown, including the following processing procedures:

[0065] In the TRI between TE and SA in the TTCN-3 test system, a port filter unit is set, and the port filter unit includes an AT command monitoring subunit, an AT command modification subunit, a TETRA terminal type identification subunit and a memory, in which The memory stores AT command sets supported by various types of TETRA terminals, and difference information between the AT command sets supported by various TETRA terminals and the standard AT command set supported by the TE.

[0066] When TE sends data to the TETRA terminal through SA, the above-mentioned AT command monitoring subunit first judges whether the data is an AT command, if the data is not an AT command, it is directly sent to SA without any modification; if the data is a...

Embodiment 3

[0072] The processing flow of a method for processing the AT command sent by the TETRA terminal to the TE in the TTCN-3 test system provided by this embodiment is as follows: Figure 4 As shown, including the following processing procedures:

[0073] In the TRI between TE and SA in the TTCN-3 test system, a port filter unit is set, and the port filter unit includes an AT command monitoring subunit, an AT command modification subunit, a TETRA terminal type identification subunit and a memory, in which The memory stores AT command sets supported by various types of TETRA terminals, and difference information between the AT command sets supported by various TETRA terminals and the standard AT command set supported by the TE.

[0074] When the TETRA terminal sends data to TE through SA, the above-mentioned AT command monitoring subunit first judges whether the data is an AT command, if the data is not an AT command, it will be directly sent to TE without any modification; if the d...

Abstract

The embodiments of the invention provide a TTCN-3-based method and apparatus for testing a TETRA terminal. The method mainly comprises the following steps: arranging a port filtering unit in a TRI in a TTCN-3 test system, storing AT instruction sets respectively supported by TETRA terminals of various types in the port filtering unit, the port filtering unit monitoring AT instructions interacted between the TETRA terminals and the TTCN-3 test system, and according to the types of the TETRA terminals for sending or receiving AT instructions and the stored AT instruction sets respectively supported by the TETRA terminals of the various types, modifying the AT instructions. According to the embodiments of the invention, the TTCN-3 test system can interact with different TETRA terminals through standard AT instructions without taking into consideration the differences of the AT instruction sets supported by the TETRA terminals produced by different manufacturers, and the complexity and difficulty of testing the TETRA terminals by the TTCN-3 test system are reduced.

Description

technical field [0001] The invention relates to the technical field of terminal testing, in particular to a method and device for testing TETRA terminals based on TTCN-3. Background technique [0002] TTCN (Testing and Test Control Notation) is a globally applicable standard test scripting language maintained by ETSI (European Telecommunications Standards Institute, European Telecommunications Standards Institute). Its third-generation standard TTCN-3 is a modern and flexible language that can describe many types of system tests through a wide range of interfaces. Typical application areas of TTCN-3 are system testing, interaction testing, protocol testing, business testing, module testing, etc. TTCN-3's platform independence and its special testing capabilities make it widely used to define the formal testing of communication systems set. [0003] At present, a schematic diagram of the overall structure of a TTCN-3 test system is as follows figure 1 shown in figure 1 Am...
