Data transmission method and system

Abstract

The invention discloses a data transmission method and a data transmission system. The method comprises the following step of: performing data exchange between an access terminal and an access network through a connectionless channel. Through the method and the device, the problems that an abrupt service of which a transmitted data packet is small is packaged in a signaling, and the transmission rate is low, the signaling transmission is influenced, the channel is jammed and the like by transmitting in a signaling mode, or the problem that abrupt data is transmitted in a connection-based data transmission mode, so that frequent disconnection and connection between the access terminal and the access network are required, the terminal consumes more electricity, the processing efficiency of the access network is influenced, null interface resources are wasted and the like in the related technology are solved, so that the jamming of the signaling channel or the aggravation of the jamming is avoided.

Description

technical field [0001] The present invention relates to the communication field, in particular, to a data transmission method and system. Background technique [0002] At present, the enhancement of the Code Division Multiple Access (CDMA for short) access technology is a focus of attention in the industry. [0003] As more and more networks and access terminals using code division multiple access technology are commercialized, for example, CDMA20001xEV-DO, this system may be called a high rate packet data (High Rate Packet Data, HRPD for short) system, Various data services based on this type of bearer network are also emerging. The most typical services include ftp downloads, video calls, etc. Compared with the original 2G or 2.5G wireless communication network, the HRPD system has a higher uplink and downlink data rate and a higher system capacity, so it can be used for the above data Business users bring a good user experience. It should be emphasized that the data fl...

Problems solved by technology

[0006] Aiming at the related technologies that will be bursty and the transmitted data packets are usually relatively small services encapsulated in signaling, and transmitted in the form of signaling, resulting in low transmission rate, affecting signaling transmission, congested channels and other problems or using The transmission of burst data based on the connection-based data transmission method will lead to frequent disassembly and construction of connections between the access terminal and the access network, resulting in more power consumption of the terminal, affecting the processing efficiency of the access network, and wasting air interface resources. The present invention, therefore, the main purpose of the present invention is to provide a data transmission scheme to solve at least one of the above-mentioned problems
