Abstract

This invention discloses a transmission method for TDM data based on packet exchange, which sets logic ports at the sending side and receiving side and sets up a mapping relation between the two ports, images the original TDM data into a packet data format by the TDM logic port when transmitting the TDM data then packages the received packet data and CID to a MAC data packet directly in terms of the set package information to be transmitted to the receiving side by the share transmission medium, the MAC layer of the receiving side obtains the de-package information and the TDM logic port ID of the receiving side based on the CID in the data packet then to de-package it to image the obtained data to related TDM logic port to realize the high efficient transmission of the TDM data.

Description

technical field

[0001] The invention relates to the technical field of communication, in particular to a time division multiplexing (TDM) data transmission method based on packet switching. Background technique

[0002] With the rapid development of network communication technology, new technologies represented by packet switching continue to emerge and develop, and the concept, system structure and operation mode of traditional telecommunication networks are also undergoing profound changes. Due to the incomparable advantages of traditional circuit switching - low cost and high bandwidth, packet switching technology has gradually changed from the initial single data service to include TDM voice, data, asynchronous transfer mode / Internet protocol (ATM / IP) and Various services such as images perform traditional circuit switching functions, such as voice (VOIP) technology based on (IP) bearer. Moreover, with the continuous improvement of the voice transmission quality of the ...

Embodiment Construction

[0035] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0036] The core idea of ​​the present invention is: set TDM logical ports respectively on the TDM data sending side and receiving side of the communication system based on the shared transmission medium, and establish the mapping relationship between the TDM logical ports on the sending side and the TDM logical ports on the receiving side; For TDM data, the original TDM data is mapped to a certain packet data format through the set logical port, and then the obtained packet data and CID are directly encapsulated into MAC data packets according to the set encapsulation information, and finally the data packets are transmitted through the shared transmission medium Send to the receiving side; on the receiving side, the MAC layer obtains the decapsulation information ...
