The communication method of the IPv6 over DTN interactive remote education system based on the Beidou short message is shown in FIG. 2: in the IPv6 over DTN interactive remote education system communication method based on the Beidou short message, a downlink of data communication comprises two stages. In the first stage, a Satellite network broadcasting center issues network resources to a Satellite network receiving server fixed in a farming and pasturing area through a Satellite channel, and an IP over DVB-S (Digital video broadcasting-Satellite, DVB-S) is adopted as a communication protocol in the first stage. The method adopts IP over DVB-S to distribute resources, and has the biggest characteristic that the method utilizes the advantage of wider downlink frequency band of satellite broadcasting to realize high-speed data broadcasting (the transmission rate can be as high as more than 60 Mbps) for users in a large range. The satellite resource sharing technology is suitable for remote areas due to the characteristics of low cost, high data rate and the like. When the IP data packet is transmitted over the DVB-S satellite link, the IP data may be encapsulated in an mpe (multi Protocol encapsulation) or ule (universal light encapsulation) manner. After acquiring related data from the resource server, the network broadcasting center encapsulates the data into an IPv6 data packet, further encapsulates the data into a DVB-S data frame (Transport Stream, TS), and utilizes a satellite broadcasting channel to transmit, thereby realizing resource distribution from the satellite broadcasting center to the satellite network receiving server. And in the second stage, the satellite network receiving server sends the received IPv6 network resource to the destination node, and an IPv6 over DTN communication protocol is adopted in the second stage. The satellite network receiving server forwards the network resource to the mobile communication node moving to the communication range of the satellite network receiving server, and then the mobile communication node in the DTN network adopts short-distance communication technologies such as Bluetooth and the like to carry out 'storage-carrying-forwarding' data to support message forwarding and provide a 'carrying' link, namely the DTN mobile communication nodes forward the carried data to other nodes in the process of contacting with each other.
In a new interactive distance education system, a satellite network reception server periodically requests an IPv6 resource list from a satellite distribution center. The DTN mobile communication node can acquire the IPv6 resource list when moving to the communication range of the satellite network receiving server, and also can acquire the IPv6 resource list from other nodes. And then selecting Data to be subscribed according to the resource list, and then generating a subscription Data packet, wherein the content of the subscription Data packet is the IPv6 address of the node and the Data ID of the subscription Data thereof.
In the interactive communication method for the farming-pasturing area content distribution system, an uplink of data communication comprises two parts. The first part is to support message forwarding by using the data transmission characteristic of the DTN mobile communication node, and the DTN mobile communication node forwards the carried subscription information to the satellite network receiving server in the process of mutual contact, so as to realize the storage of the service request, namely the reverse return information. And the second part verifies and analyzes the received subscription information by the satellite network receiving server, encapsulates the subscription information into a Beidou short message format, sends the user subscription information to the BD gateway through the Beidou short message receiving and sending equipment, and sends the user subscription information to the broadcasting server after the user subscription information is analyzed by the BD gateway, so that the reverse feedback of the subscription information is completed.
