Testing method and system for testing CMMB (China Mobile Multimedia Broadcasting) network coverage

Abstract

The invention provides a testing method for testing CMMB (China Mobile Multimedia Broadcasting) network coverage, comprising the following steps that a CMMB testing and receiving plate receives CMMB signals and sends the receiving analysis data to a data processing module according to the CMMB signals; the data processing module determines the field intensity and the receiving performance at the specific position according to the receiving analysis data as well as the field intensity signal and the latitude and longitude information, and displays the real-time statistic information of the field intensity and the error code at the current time according to the field intensity and the receiving performance at the specific position. According to the technical scheme in the invention, the difference of different interfaces is shielded by a software way; the testing data, the time and the geographical information are combined by a GIS (Global Information system) component; the testing process is displayed vividly and visually; and the test on CMMB network coverage is realized effectively.

Description

technical field [0001] The invention relates to the technical field of digital information transmission, in particular to a test method and system for CMMB network coverage. Background technique [0002] At present, regardless of whether it is communication services in the wired or wireless field, multimedia services have become the main services operators provide to customers. Among them, in the field of wireless communication, wireless broadcast communication has the characteristics of wide coverage and large program capacity. Its biggest advantage is that it is broadcast, realizes point-to-multipoint, and has high transmission bandwidth under low-cost conditions. Therefore, as an important part of the information communication industry, wireless communication broadcasting plays an important role in the construction of national information infrastructure, the realization of universal service and the national information security strategy. [0003] Among various multimedia...
