Problems solved by technology
[0006] Existing microwave equipment cannot control the modulation mode and channel bandwidth, but has always used a high-order modulation mode and the largest channel bandwidth
When microwave equipment is used as mobile backhaul equipment to transmit Ethernet data between base stations and base station controllers, due to the mobile characteristics of wireless terminals and the burst characteristics of Ethernet data, the air interface link is actually useful in a specific period of time. The business data traffic will be much smaller than the business data traffic planned by the network. For example, in office-intensive areas, the business data traffic during non-working hours and at night will be much smaller than working hours. Therefore, microwave devices have always adopted high-order modulation modes. The maximum Channel bandwidth and higher transmission power will increase the power consumption of microwave equipment, and also increase the electromagnetic pollution to the environment

The embodiment of the invention provides a data transmission method, microwave equipment and a network system. The data transmission method comprises the following steps: receiving a service flow of a client; counting the service traffic of the client to be transmitted in the preset time period according to the received service flow of the client; determining transmission control parameters to beused at present according to the counted service traffic of the client, wherein the transmission control parameters comprise a modulation mode and a channel bandwidth; acquiring an idle frame by processing the service flow of the client according to the determined transmission control parameters; and transmitting the idle frame. Due to the use of the technical scheme of the embodiment of the invention, the modulation mode and the channel bandwidth can be controlled according to the traffic.
Description
technical field [0001] The invention relates to the technical field of communication, in particular to a data sending method, microwave equipment and a network system. Background technique [0002] Microwave transmission data does not need to lay optical fibers or cables, but directly transmits data through space, which has obvious engineering advantages in densely built urban areas, and because of the flexible and convenient networking and use, microwave transmission is widely used in wireless base station backhaul ( Backhaul). [0003] Microwave transmission requires microwave equipment to support Adaptive Modulation (Adaptive Modulation, AM) / Adaptive Coding and Modulation (Adaptive Coding and Modulation, ACM) technology, and support Automatic Transmission Power Control (Automatic Transfer Power Control, ATPC) technology and adaptive channel bandwidth (Adaptive Channel Bandwidth, ACB) adjustment technology. Among them, the core of AM / ACM technology is to change the codin...
