Abstract

The invention discloses a data sending method, a receiving method and a transmission method for realizing data reliability based on N + 1 paths of E1 channels. The network architecture of the data sending method comprises a sending side user service layer, a sending side data adaptation layer and a sending side physical transmission layer, wherein the sending side user service layer is used for generating user data, the sending side data adaptation layer carries out necessary adaptation and processing on user data, and the sending side physical transmission layer obtains the data from the data adaptation layer and carries out data transmission through (N + 1) paths of E1 physical channels. When one channel in the N E1 channels for transmitting the user data has an error code in the transmission process, the error code can be corrected at a receiving end, so that correct transmission of the data is realized; when one of the N E1 channels for transmitting the user data is disconnected, the data on the E1 channel can still be recovered through operation processing at the receiving end, and correct transmission of the data is achieved.

Description

technical field [0001] The invention relates to the technical field of digital communication, in particular to a reliable data transmission method based on N+1 E1 channels. Background technique [0002] In the field of data communication, the application of bundling multiple E1 physical channels into a single logical data channel for data transmission is very common. In these applications, the user equipment splits and encapsulates the data to be transmitted at the sending end and sends it through multiple E1 channels, and at the receiving end reassembles the data received from multiple E1 channels and restores them to the original data. This application technology can use multiple low-bandwidth physical data transmission channels to form a single high-bandwidth data channel to realize high-bandwidth data transmission applications, but there are still some problems that need to be improved and solved in practical applications. [0003] The E1 channel is affected by factors ...
