More Information
Summary: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.
