Apparatus and method for detecting multimedia signal receiving performance of mobile terminal

Abstract

The present invention discloses a device for detecting the performance of mobile terminal for receiving the multimedia signal and a method thereof. The method comprises the following steps: analyzing synchronous signal code out from the multimedia signal code which is received and demodulated from the mobile terminal, comparing the synchronous signal code to the standard synchronous signal code for calculating the frame error code rate, and obtaining the performance of mobile terminal for receiving the multimedia signal according to the frame error code rate. The invention realizes the detection objects of high efficiency, flexibility and low cost.

Description

technical field [0001] The invention relates to the field of wireless mobile communication, more specifically, to a device and method for detecting the performance of a mobile terminal receiving multimedia signals. Background technique [0002] Mobile multimedia broadcasting has increasingly become a hot spot in the market, and its technology development and standards are updated rapidly. For example, the European digital video broadcasting handheld receiving transmission standard DVB-H, the American multimedia single forward link standard (MediaFLO) and the China Mobile Multimedia Broadcasting standard (CMMB, China MobileMultimedia Broadcasting) and so on. China Mobile Multimedia Broadcasting Standard (CMMB) is a transmission through satellite and terrestrial wireless broadcasting. The system realizes the seamless coverage of receiving broadcast TV service anytime and anywhere on a mobile portable terminal. [0003] The China Mobile Multimedia Broadcasting industry standa...

Problems solved by technology

In actual communication, there are various interferences and noises. For example, my country's mobile multimedia broadcasting operating frequency band: 2.635~2.66GHz; 470~798MHz. There are GSM900MHz, CDMA800MHz, 2.4GHz IMS (IP Multimedia Subsystem, IP Multimedia subsystem) frequency band and other interference and various noises, so even if the signal is not very weak, the mobile multimedia broadcasting network cannot be searched, mainly because the signal-to-noise ratio is too low and the signal cannot be demodulated.

[0007] In order to be able to detect the reception situation of the mobile multimedia broadcasting service in the current mobile terminal, many instruments are mainly used for testing in the prior art, such as in the national industry standard "Technical Requirements and Test Methods for Terminal Reception Performance of Mobile Multimedia Broadcasting Service" It can be seen that many expensive instruments (such as Figure 4 shown), and this method causes low detection efficiency, and the detection cost is very high due to the expensive instrument
