Problems solved by technology

[0006] Most of the existing space-ground integrated communication management protocols only propose communication methods for individual fields. These methods rely on established rules or limited use scenarios, and have the following problems that have not been resolved: service processing time extension, protocol design redundancy, and inability to meet Comprehensive coverage of space-earth management and control functional requirements, etc.

Embodiment example

[0200] Instance of query interaction process:

[0201] S11. The data collection and distribution system sends a query message Inquire{MessageType=1, agentID=1, infoID=1, sign=1, variableBindings='1.1.0.1:0:1.1.0.2:1'} to the management and control agent center, for To ensure the reliability and security of data message transmission, encrypt the message, the encrypted data is: [-40,109,-31,52,-23,8,36,-69,36,36,-65 ,53,57,-33,-93,-94,-110,44,97,109,-54,92,114,25.66,-1,-39,-82,-9,-49,71,-100,-37,124 ].

[0202] S12. The management and control agent center continuously monitors whether the message is received. After receiving the message, it first decodes and checks the integrity, and after confirming that the data is not lost, obtains the query message Inquire{MessageType=1, agentID=1, infoID =1, sign=1, variableBindings='1.1.0.1:0:1.1.0.2:1'}; according to MessageType=1, we know that we need to query, start query according to the requirements of the query message, and send it...

Abstract

The invention discloses a space-ground integrated network communication management protocol and method, and the method comprises the steps: transmitting a first message to a target management and control agent, and enabling the first message to be determined through the corresponding configuration of a protocol header in a preset format according to the demands of a user; and receiving a simple response message which is sent by the target management and control agent and corresponds to the user demand, and / or receiving a detailed response message which is sent by the target management and control agent and corresponds to the user demand. According to the method disclosed by the invention, corresponding configuration determination is carried out by utilizing the protocol header in the preset format according to the user demand through the first message, and the corresponding response message can be received according to the protocol in the preset format, so that a unified framework, a unified system and a unified standard are adopted between space-based management and control and ground-based management and control, and wide-area networking seamless coverage is realized.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a communication management protocol and method for an integrated space-ground network. Background technique [0002] In recent years, with the continuous maturity of computer network technology, network communication has received extensive attention and has gradually penetrated into people's life, study and work, so it has important research value and application prospects. Computer networks, especially the Transmission Control Protocol / Internet Protocol (hereinafter referred to as TCP / IP) networks, are the basis of global information communication protocols. In order to realize information communication, various organizations have established their own Ethernet net. [0003] At present, an IP-based local area network has been built inside the International Space Station, and astronauts can access the ground Internet inside the International Space Station. The space-grou...
