Embodiment Construction

[0027] The specific implementation manner of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0028] FIG. 1 is a schematic diagram of a data structure of a radio frame used in the multi-service transmission method in microwave communication provided by the present invention.

[0029] The data structure of a kind of radio frame used by the present invention is shown in Figure 1, and it is made up of a plurality of cell (CELL), and each cell further includes overhead byte (OVERHEAD) and business data. Each cell contains service data of the same data length, and the service data in each cell belongs to the same service type.

[0030] Wherein, the overhead byte is further composed of cell identifier, cell sequence number, verification of service data, etc., and the overhead byte particularly includes the service type and the verification of the service type. The overhead bytes are not necessarily all limited to the header of...

Abstract

The present invention relates to a multi-service transmission method in microwave communication, which comprises a multi-service data sending method and a multi-service data acceptance method. Wherein, the multi-service data sending method comprises the following steps: judging the priority of service type; judging whether the service data reaches the given packaging length, adding the type of service; packaging the service data of relevant type; adding invalid data mark when the service data does not reach the given packaging length; packaging the invalid data and sending the radio frame. The multi-service data acceptance method comprises the following steps: receiving the radio frame, discerning the service type in the radio frame, unpacking the service data according to the identified service type, discerning the invalid data mark in the radio frame and discarding the invalid data.

Description

technical field [0001] The invention relates to the field of wireless communication, in particular to a multi-service transmission method in microwave communication. Background technique [0002] In the data transmission of microwave communication, in order to ensure the synchronization of sent / received data, continuous transmission of microwave signals is required. In general, a transmission / reception unit whose data length is predetermined during microwave transmission is called a radio frame. That is, continuous transmission / reception of radio frames is required. [0003] However, in microwave communication, there are many types of services to be transmitted, and the data processing rates of each service type are also different. [0004] The existing technical solution is to predetermine the transmission data format for the wireless frame, that is, predetermine the combination of the service types to be transmitted, and allocate a fixed position and length of data space...
