Problems solved by technology

[0012] However, in the current test system, the information related to the radio frequency of the test case needs to be checked and verified in the relevant message, which cannot directly reflect the frequency point information of multi-frequency points and / or multi-bands

Embodiment 1

[0036] The protocol conformance testing system of the first preferred embodiment of the present invention is as follows: image 3 As shown, it is a test system based on TTCN. The channel emulator is respectively connected to the transmitting end (TX) and receiving end (RX) of the traditional system simulator (SS) including the control host and special instruments, and connected to the test terminal (UE) through a circulator.

[0037] In order to increase the verification of the frequency information and ensure that the actual bearer frequency point information of the test terminal on the user plane can be visually analyzed, a spectrum analyzer is connected to the receiving end of the system simulator through a power divider (not shown in the figure), and at the same time The spectrum analyzer is also connected to the system simulator through GPIB or USB interface.

[0038] The test script written by TTCN is run on the control host. By extracting the frequency point informatio...

Embodiment 2

[0060] Figure 4 Shown is a protocol conformance test system of another preferred embodiment of the present invention, which is an IOT-based test system. The system consists of RNC simulator and Node B base station. Wherein, the RNC emulator functions as the RNC and part of the CN in the actual network. RNC simulator control software and protocol conformance test script. Write a test case script on the RNC simulator to control NodeB and complete the protocol conformance test.

[0061] In order to increase the verification of frequency information and ensure that the actual bearer frequency point information of the test terminal on the user plane can be visually analyzed, the spectrum analyzer is also connected to the receiving end of the Node B base station through a power divider (not shown in the figure). And through the GPIB or USB interface to connect to the RNC simulator to monitor the frequency point information. Similar to Embodiment 1, related parameters such as th...

Abstract

The invention proposes a system and a method for testing multi-frequency point, multi-frequency range or multi-carrier protocol consistency. The system can control parameters relevant to center frequency point, sweep bandwidth, sweep interval and the like, and can straightly analyze the actual bearing frequency point information of a testing terminal in a user interface by extracting the frequency point information in the information sent by a system stimulator or an RNC (Radio Network Controller) stimulator through testing scripts and sending commands to monitor a spectrum analyzer.

Description

technical field [0001] The invention relates to a test system and a test method for items such as multi-frequency points, multi-frequency bands or multi-carriers in the protocol consistency test. Background technique [0002] The terminal protocol conformance test is aimed at the terminal air interface (Uu interface) protocol stack, including detailed testing of the functions of each entity from layer 2 (bottom layer) to non-access related layer (high layer). It mainly verifies whether the signaling process or key message fields of each layer of the terminal protocol stack conform to the core specification under normal or abnormal communication status. [0003] At present, the content of the terminal protocol conformance test mainly refers to the international specification 3GPPTS34.123-1, including idle mode operation, layer 2, radio resource control (RRC), mobility management (MM), circuit domain call control (CC), session management (SM), packet domain mobility managemen...
