Embodiment Construction

[0022] The embodiment of the invention discloses a method, device and system for packet data transmission.

[0023] The embodiment of the present invention first encapsulates the data into a TRAU frame when the sending end sends data, and then encapsulates the TRAU frame as a packet transmission payload in an HDLC data frame into an advanced data link control (High-Level Data Link Control, The frame format of the HDLC) data frame, the HDLC data frame is sent to the receiving end through the Abis interface or the Ater interface; at the receiving end, the receiving end receives the HDLC data frame, obtains the frame check sequence FCS field according to the received HDLC data frame, and confirms Whether the data is received correctly; if received correctly, establish a receiving context (context) according to the address field in the HDLC data, and buffer the received user data.

[0024] The specific implementation manners of the embodiments of the present invention will be furt...

Abstract

The embodiment of the invention provides a method, a device and a system for transmitting group data. The method includes: a sending end encapsulating the data into TRAU frame which contains a transmission control bit and a user data bit; the sending end encapsulating the TRAU frame into HDLC data frame, the TRAU frame is playload group transmitted in the HDLC data frame; the sending end sending the HDLC data frame to a receiving end via an Abis interface or an After interface. The embodiment of the invention encapsulates the data into the HDLC data frame to achieve the data transmission group, which is simple and easy to achieve, based on a little improvement on the prior transmission network; solves the problems of too high cost of the TDM device, and low utilization rate of bandwidth caused by that the TDM transmission momopolizes the transmission channel.

Description

technical field [0001] The present invention relates to data transmission technology, in particular to a method, device and system for packet data transmission. Background technique [0002] GSM (Global System for Mobile Communications, Global System for Mobile Communications) system includes three subsystems, such as figure 1 As shown, there are three parts: Network Subsystem (NSS), Base Station Subsystem (BSS) and Operation Support Subsystem (OSS). [0003] The Network Subsystem (NSS) mainly includes the switching function of the GSM system and the database function required for user data, mobility management, and security management. Inter-communication plays a management role. [0004] The operating subsystem OSS mainly completes functions such as mobile user management, mobile device management, and network operation and maintenance. [0005] The base station subsystem (BSS) is the most directly related basic component of the wireless cellular aspect in the GSM syste...
