Example Embodiment

[0045] Example one

[0046] In the embodiment of the present invention, a port filtering unit is set in the TRI of 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 filtering unit. The port filtering unit monitors and modifies the data transmitted between SA and TE to achieve the purpose of eliminating the difference between TETRA terminals.

[0047] The embodiment provides a processing flow of a method for testing TETRA terminals based on TTCN-3. figure 2 As shown, including the following processing steps:

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

[0049] The main differences between the AT command sets supported by TETRA terminals produced by different manufacturers are as follows:

[0050] (1) The difference of AT command parameter format ...

Example Embodiment

[0063] Example two

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

[0065] A port filtering unit is set in the TRI between TE and SA in the TTCN-3 test system. The port filtering unit includes an AT command listening subunit, an AT command modifying subunit, a TETRA terminal type identifying subunit, and a memory. 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 AT command monitoring subunit first judges whether the data is an AT command. If the data is not an AT command, it will be sent directly to SA without any modification; if the data is an AT command, ...

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...
