Embodiment 1

[0074] The test system in the present invention will be described in detail below.

[0075] Such as Figure 1-4 Shown, the test system of the wireless network data service among the present invention comprises:

[0076]a, test terminal 11 (TD-SCDMA standard), for carrying out VT test with core network or other test terminals by wireless network, this terminal supports the wireless air protocol of TD-SCDMA standard, HSDPA / HSUPA, HSDPA+ or LTE,. In this embodiment, several test terminals can be placed everywhere, and these terminals can automatically initiate some tests (such as making video calls, sending and receiving short messages, watching streaming media images) through remote control. The test terminals can also include fixed test terminals and mobile dial test terminals with GPS functions. Among the fixed test terminals, 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 networ...

Embodiment 2

[0088] 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 firstly introduces the VT test method of the terminal to the core network, which includes routine test and real-time test. Specifically include the following steps:

[0089] Step 101, the test terminal acquires a routine test scheme or a real-time test scheme. Wherein, during the routine test, in this embodiment, a routine test scheme may be prepared in advance through the core network and delivered to the test terminal, and the test terminal will perform the test according to this scheme thereafter. The content of the test plan includes the time when the test is initiated, the source image file used in the test, the image encoding used in the test, the time length of playing the source image in the test, etc. During real-time testing, in this embodiment, the engineer formulates the tes...

Embodiment 3

[0100] The following describes the terminal-to-terminal testing method, which includes routine testing and real-time testing. The testing terminals in the testing system include calling testing terminals and called testing terminals. Specifically include the following steps:

[0101] Step 201, the calling and called testing terminals acquire routine testing schemes or real-time testing schemes. In this embodiment, the method for obtaining the routine test scheme and the real-time test scheme and the content of the test scheme are basically the same as those in Embodiment 2, and will not be repeated here.

[0102] 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 (information related to the VT call such as number and code).

[0103] Step 203, the calling and called testing terminals perform VT video synchronization. The synchronization met...

Abstract

The invention discloses a system and a method for testing the user perception effect of video telephony (VT) and streaming media, which are applied to video services in a time division-synchronization code division multiple access (TD-SCDMA) / high speed downlink package access (HSDPA) / high speed uplink package access (HSUPA) / high speed packet access + (HSPA+) / long term evolution (LTE) system. The system comprises TD-SCDMA system 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 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 the video services, such as video telephony and streaming media services, in a TD / SCDMA / HSDPA / HSUPA / HSPA+ / LTE 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 3G mobile communication technology of TD-SCDMA-HSDPA / HSUPA-HSPA+-LTE standard, mobile Internet technology, unattended embedded platform terminal research and development technology, video service user perception test and evaluation technology (including but not limited to ITU-T The PEVQ algorithm, MDI, MOS_V algorithm, etc. that have been formulated or are being formulated or will be formulated) belong to a test system for end-to-end testing of the user perception effect of wireless network video services (video calls, streaming video playback). Background technique [0002] TD-SCDMA is one of the three major 3G standards in the world (the other two are the CDMA-EVDO standard proposed by Qualcomm and the WCDMA standard proposed by Europe). This standard of 3G technology has been widely used in China. The evolution route of TD-SCDMA standard to 4G is: TD-SCDMA--HSDPA / HSUPA--HSPA+--LTE. TD-SCDMA is a typical 3G, that is...
