Embodiment 1

[0073] The test system in the present invention will be specifically described below.

[0074] Such as Figure 1-4 As shown, the test system in the present invention includes:

[0075] a. The test terminal 11 is used to perform a VT test with the core network or other test terminals through the wireless network. In this embodiment, several test terminals can be placed everywhere, and these terminals can be remotely controlled to automatically initiate some tests (such as making video calls, sending and receiving short messages, watching streaming media images). The test terminal can also include a fixed test terminal and a mobile dial test terminal with GPS function. In the fixed test terminal, in addition to the 3G wireless data function, there is also a WiFi function, which can be used to wirelessly upload the test results to the core network.

[0076] Such as figure 2 As a test terminal used in this embodiment, BP (baseband processing module 112) is the wireless baseband proces...

Embodiment 2

[0087] The test method of the test system in the present invention is divided into three types: terminal-to-core network, terminal-to-terminal VT test, and streaming media test. The following first introduces the VT test method of the terminal to the core network, which includes two kinds of routine test and real-time test. It includes the following steps:

[0088] Step 101: The test terminal obtains a routine test plan or a real-time test plan. Among them, during routine testing, in this embodiment, a routine test plan can be formulated in advance through the core network to deliver the test terminal, and then the test terminal is tested according to this plan. The test plan includes the time when the test is initiated, the source image file used during the test, the image encoding used during the test, and the length of time the source image is played during the test. In real-time testing, in this embodiment, the engineer formulates a test plan through the web interface, or e...

Embodiment 3

[0101] The following describes the terminal-to-terminal test method, which also includes routine testing and real-time testing. The test terminals in the test system include the calling test terminal and the called test terminal. It includes the following steps:

[0102] Step 201: The calling and called test terminals obtain a routine test plan or a real-time test plan. In this embodiment, the method for obtaining the routine test plan and the real-time test plan and the content of the test plan are basically the same as those in the second embodiment, and will not be repeated.

[0103] Step 202: At a predetermined time, the calling test terminal initiates a VT call to the called test terminal, and establishes a VT call connection according to the content of the test plan (number, code, and other information related to the VT call).

[0104] Step 203: The calling and called test terminals perform VT video synchronization. The synchronization method is the same as that in Embodiment...

Abstract

The invention discloses a system and a method for testing the user perception effect of video telephony (VT) and streaming media. The system comprises test terminals, a VT video test server, a result analysis server, a streaming media test server, a central database, a short message application server, an online upgrade server, a Web server and an application logic server, wherein the application logic server is connected with the test terminals, the central database and each server; and the test terminals, the central database and each server perform data exchange by the application logic server. The system for testing the user perception effect of video telephony and streaming media services in a code division multiple access (CDMA)/evolution-data optimized (EVDO) wireless network is flexibly deployed, automatically run, remotely controlled and upgraded and easy to use, and can conveniently and highly-efficiently detect the running quality of the VT and streaming media services in the wireless network, and obtain 7*24-hour test results of a great number of test points by arranging the test terminals in different environments without huge manpower and material resources.

Description

Technical field [0001] The present invention relates to CDMA-EVDO standard 3G mobile communication technology, mobile Internet technology, unattended embedded platform terminal research and development technology, video service user perception test evaluation technology (including but not limited to ITU-T has been formulated or is being developed or will be developed The PEVQ algorithm, MDI, MOS_V algorithm, etc.) belong to a test system for end-to-end testing of user perception effects of wireless network video services (video calls, streaming video playback). Background technique [0002] In the existing CDMA-EVDO standard 3G wireless network, the application of real-time video services is rapidly increasing. For example, video calls, the business can evolve into video surveillance; for example, streaming media video business, the business can evolve into mobile TV; these services can bring new profit growth points for operators. However, if the video effect is not good, it wi...
