Problems solved by technology

[0009] The disadvantage of the solution in the prior art is: in actual network applications, the network side equipment and the base station side equipment usually have a relatively long distance, even between different cities
Therefore, it is difficult to reset the device or IMA group at both ends of the network side and the base station side manually, and it is also difficult to re-establish the connection at the two ends of the network side and the base station side, which will lead to network failure. Maintenance workload is very high

Embodiment Construction

[0030] The present invention provides a method for transmitting control information in an asynchronous transmission mode reverse multiplexing link. The core of the present invention is: when the IMA is abnormal, the IMA link control information is transferred between the network side and the base station side through the E1 idle time slot, and the connection is re-established on the network side and the base station side.

[0031] In order to better describe the present invention, we first briefly introduce the E1 system and the frame structure of E1.

[0032] The E1 system is a commonly used physical layer interface, and the IMA function is usually implemented in an ATM network based on E1. The E1 system is recommended by ITU-T (International Telecommunication Union-Telecommunications Standards Department). Its electrical interface complies with G.703, frame structure complies with G.704, and E1 is a standard physical layer interface. The physical connection includes one receivin...

Abstract

The present invention relates to a asynchronous transfer mode reversal multiplexing link transfer control information method. Said method includes filling control information transmitted between network and base station side equipment of link required use IMA (asynchronous transfer Mode asynchronous transfer mode reversal multiplexing) to physical layer frame idleness time slot; through said physical layer frame idleness time slot transmitting said control information between IMA link network side and base station side equipment. Said invented method can provide an automatic recovery connection means between IMA link network side and base station side, reducing network maintenance work load and operating cost.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a method for transmitting control information through an asynchronous transmission mode reverse multiplexing link. Background technique [0002] ATM (Asynchronous Transfer Mode) is a data transmission technology. It is based on asynchronous time division multiplexing and is suitable for local area networks and wide area networks. It has high-speed data transmission rates and supports many types such as voice, data, and fax. , Real-time video, audio and image communication, ATM supports IMA (Inverse Multiplexing of ATM) technology. [0003] IMA is a standard physical layer transmission protocol proposed by the ATM Forum. IMA can merge multiple physical links into a logical link. The rate of the combined logical link is similar to the sum of the rates of each physical link. The basic principles of IMA are as follows figure 1 Shown. [0004] The basic principle of IMA is: at the sen...
