Method and device for transmitting data

Abstract

Disclosed are a method and apparatus for transmitting data, which relate to the technical field of information and can prevent the interruption of service data transmission. The method comprises: firstly, a microwave device sending end acquiring a symbol rate switching direction, determining at least three symbol rates for sending an air interface frame according to a symbol rate of the air interface frame before adjustment and the symbol rate switching direction, and sending the air interface frame to a microwave device receiving end by means of the at least three symbol rates, wherein the air interface frame carries service data; then, the microwave device receiving end receiving the air interface frame sent by the microwave device sending end, and determining a symbol rate for demodulating the air interface frame; and finally, the microwave device receiving end demodulating the air interface frame according to the symbol rate for demodulating the air interface frame, so as to obtain the service data. The present invention is applicable to a microwave device sending end sending an air interface frame carrying service data to a microwave device receiving end, and the microwave device receiving end demodulating the air interface frame and acquiring the service data according to an acquired symbol rate for demodulating the air interface frame.

Description

technical field [0001] The invention relates to the field of information technology, in particular to a method and device for transmitting data. Background technique [0002] With the development of information technology, microwave technology develops accordingly. However, microwave transmission is greatly affected by the weather. When the weather is severe, service data is transmitted through microwave, which will cause the receiving end of microwave equipment to fail to receive service data. [0003] At present, there is a data transmission method. When the receiving end of the microwave equipment cannot receive service data, the receiving end of the microwave equipment sends an indication message to the transmitting end of the microwave equipment to instruct the transmitting end of the microwave equipment to adjust the symbol rate of sending air interface frames according to a multiple. Then the transmitting end of the microwave device sends the transition frame accordin...

Problems solved by technology

[0004] However, when the microwave device first sends the transition frame until the microwave device receiver receives the transition frame, when the microwave device sender sends the air interface frame carrying service data, since the microwave device sender adjusts the symbol rate of the air interface frame according to the multiple , the symbol rate adjustment range is relatively large, so the transmitter of the microwave device needs to send transition frames with two different symbol rates to the receiver of the microwave device until the link is established, and the transition frame does not carry business data, and the receiver of the microwave device does not Unable to receive all transition frames, resulting in interruption of service data transmission
