Description
Technical field
The present invention relates to the mobile communication technology field, relate in particular to a kind of data transmission method, device and data receive method and device.
Background technology
In recent years, digital mobile multimedia broadcasting technology and standard evolution are rapid, for example, DVB-H (the Digital Video Broadcast Handheld in Europe, the digital video broadcast-handheld formula receives), the MediaFLO of the U.S. (Media Forward Link Only, the single forward link of medium) and China CMMB (China Mobile Multimedia Broadcasting, Mobile Multimedia Broadcasting) etc., various standards provide multiple service content for the terminal use, as: advertisement, weather forecast, news, sports cast, variety, programs such as multimedia broadcasting play and film, the user can select the service program of Mobile Multimedia Broadcasting according to the hobby of oneself.
China mobile multi-media broadcasting technology adopts time division multiplexing mode to send multi-media broadcasting service, and the duration of its broadcast channel frame is 1 second, is made up of 40 25 milliseconds time slot, and one or more time slots can transmit the data of a multiplexed frame encapsulation.As shown in Figure 1, in the multiplexed frame structure of Mobile Multimedia Broadcasting, multiplexed frame is divided into multiplex frame head, multiplexed frame payload and fills three parts.The mode that China mobile multi-media broadcasting technology adopts control information to separate with business datum sends, and as shown in Figure 2, when time slot during as control channel, corresponding multiplexed frame (MF_ID=0) encapsulates control information; As described in Figure 3, when time slot during as data channel, corresponding multiplexed frame (multiplexed frame MF_ID ≠ 0) encapsulation business datum, the service integration frame is divided into a plurality of multiplexed sub frames again, each subframe encapsulate video section, audio section and data segment.Business of each multiplexed sub frame carrying, and the data segment in the multiplexed sub frame is used for the encapsulation of packet.
Data service in the Mobile Multimedia Broadcasting (stock information and info web etc. are provided) is based on the data transmission technology realization.Data transmission technology mainly is divided into stream mode and file mode, stream mode is meant that business datum transmits in the mode of Continuous Flow, the sequential requirement is arranged usually, transmit free label indication or data flow inside synchronous requirement is arranged, but require lower to the data integrality, for example, stock information, audio stream and video flowing etc.; File mode is meant that business datum transmits in the mode of discrete data file, does not have the sequential requirement usually, transmit no time tag or synchronous requirement, but to the requirement of data integrality than higher, for example, picture, webpage and plug-in unit etc.The packet of data service generally is encapsulated in the data segment of multiplexed frame.
In multimedia broadcasting, the data of different business are separate, and promptly a multiplexed sub frame only transmits a business, and each business takies certain time sequence, transmits data in its shared sequential.And if certain professional data volume is less or can not pass data the time, the less data of even not carrying of the data that the data segment of the corresponding multiplexed sub frame of this business carries, this has just caused waste of radio resources.In addition, the transfer of data of data broadcast service, the length of the data segment that each is professional is fixed, and for the transmission of the especially big file of file, speed is slow, and information updating is untimely.
