[0003]
The existing multi-link parallel transmission method is more concerned with the system utility, and the power business is different, and different business priorities have different requirements on the network, such as network delay, bandwidth, bit error rate, and cost. etc. Therefore, the existing multi-link parallel transmission methods often cannot meet the transmission requirements of power service data

Embodiment Construction
[0034] In order to make the purpose, features and advantages of the invention of the present application more obvious and understandable, the technical solutions in the embodiments of the present application will be clearly, completely and carefully described below in conjunction with the drawings in the embodiments of the present application.
[0035] When there are multiple links in the power heterogeneous network, the method divides the data into data packets of different sizes and distributes them to multiple links in the network for simultaneous transmission. According to the delay, security, reliability and other requirements of different power services, the data packet size can be dynamically adjusted and distributed to different networks, and the uplink can be actively allocated according to the real-time bandwidth of several communication links and the size of their real-time data volume Data, improve wireless data transmission efficiency, stability and data throughput...

A wireless heterogeneous network multi-link data distribution method based on service priorities comprises the following steps: a, detecting, by multi-mode terminal equipment, an accessible network set to acquire the parameters of corresponding channels; b, carrying out service classification on the transmission data, and calculating the data size of the corresponding service; c, when a single network cannot meet service transmission requirements, selecting m networks and corresponding data distribution strategies according to the requirements of services for network attributes and channel parameters of the networks, and dividing the service data into m sections of data packets with different sizes according to the distribution strategies; d, assigning the data packets to corresponding networks; and e, after receiving the data packet, recombining the core network the data packet to complete data transmission. According to different requirements of different power businesses on the network and each network channel parameter, the size of the data packet is dynamically adjusted, and the data packet is allocated to different networks, so that the wireless data transmission efficiency, stability and data throughput can be improved, and the communication reliability and the system performance are further improved.
Description
technical field [0001] The invention relates to a network multi-link data distribution method, which belongs to the technical field of communication. Background technique [0002] With the diversification of power services and the access of a large number of terminals, the power communication network is becoming more and more complex. Different services have different QoS requirements. Some power services require greater bandwidth and lower delay. Traditional power wireless private networks It is no longer able to meet business needs. In order to meet business needs, Wi-Fi, UWB, WiMAX, 3G, 4G, 5G and other emerging wireless network technologies provide a variety of options for the current power communication network. Since most wireless networks at this stage have heterogeneous characteristics and can provide various business services and high-quality, massive data business transmission, the "private network + public network" network forms a power heterogeneous The network...
