Embodiment Construction

[0040] Functional Overview

[0041]The embodiment of the present invention provides a data transmission scheme, which provides a new data transmission mode for data services (especially bursty data services), and this transmission mode will separate data transmission from signaling transmission to avoid causing or aggravating the congestion of the signaling channel. When necessary, the access terminal (that is, the terminal) and the access network adopting this data transmission mode can conveniently transfer to the connected state, and establish a dedicated service channel for subsequent data transmission. This way can be completely backward compatible with the existing HRPD system. In this solution, by introducing forward / reverse shared connectionless channels, access terminals do not need to establish dedicated service channels when starting burst data service applications, but can share the same group of forward / reverse connectionless channels. According to the current wi...

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...
