Description
Technical field
The present invention relates to a kind of method of dynamically regulating data transfer rate in wireless application service system.Especially, the invention provides a kind of on the Based Intelligent Control service equipment of described wireless application service system according to different quality class stores data, and dynamically adjust and the method for wireless communication user terminal room transmission rate by the data of selecting the different quality grade.
Background technology
WLAN (wireless local area network) and public wireless communication network be comparative maturity technically at present, and has obtained using widely.Common wireless communication net wherein, comprise such as GSM/GPRS/EDGE, WCDMA/HSDPA/HSUPA/HSPA+, CDMA/CDMA2000/CDMA2000-EVDO, TD-SCDMA/HSDPA/HSUPA/HSPA+ and LTE system etc., it is advantageous that coverage is very wide, the user can roam into each country easily.The use of intelligent terminal such as mobile phone is very convenient and extensively in the common wireless communication net, become requisite personal electronic equipments in current people's life.System such as WLAN (wireless local area network) such as WIFI then has advantages such as networking is convenient, flexible, radiation is low, user's available bandwidth is bigger.
Existing wireless application service system transmits data by WLAN (wireless local area network) and public wireless communication network substantially, as information such as video and voice datas, and the intelligent wireless terminals such as mobile phone of handing to the user.Because the user who serves in cordless communication network is very many, limited bandwidth is shared by a plurality of users, the customer requirements data quantity transmitted occurs through regular meeting and makes transmission link congested situation occur greatly.
Congested measurement report mechanism has been realized preventing in common wireless communication net inside, as measurement and the feedback that the signal strength signal intensity of Serving cell and adjacent sub-district, path loss, wireless channel carrier/interface ratio etc. are carried out, to the transmit buffer of layer two, the measurement of crc error ratio B LER on the transmission channel and feedback etc., and feed back to network equipment by mobile phone and control the better sub-district of handset-selected signal quality, and select different transformats to carry out data to send.These methods have guaranteed the transmission quality between the network equipment in mobile phone and the common wireless communication net, but can't realize the control to end-to-end transmission quality, can't control the transmission rate that sends data from the source.
The most modes of using http protocol to download and play behind the audio, video data on the transfer server of wireless communication user terminal in the existing wireless application service system, this mode can't satisfy real-time broadcast and dynamically adjust the requirement of transmission rate.Some system has then adopted the RTSP/RTP/RTCP agreement to carry out the real time flow medium transmission between wireless communication user terminal and server, wherein rtcp protocol has been set up effective mechanism to end-to-end transmission quality control, but do not comprise the distinctive parameter of combining wireless transmission environment, carry out the judgement that transmission rate is adjusted as signal strength signal intensity RSSI, path loss, signal to noise ratio etc.Therefore need provide a kind of better method to be implemented in the wireless application service system, dynamically adjust transmission rate between wireless terminal, server and the data acquisition equipment, to reach better real-time transmission data, guarantee broadcast service quality in the wireless communication user terminal to the wireless communication user terminal.
Summary of the invention
