Abstract
The invention discloses a safe and reliable communication method between the Beidou operation center and branch centers. The Beidou operation center is a server, the branch centers are clients, and the clients and the serve can communicate with each other through a request response mode. The clients have access to the Beidou operation center server to transmit request message to the server. After the server receives the request of the clients, the server can immediately respond the request and return response message if the server can respond the request in time, or the server returns response message to show that the request has been received if the server cannot respond the request in time. After data are processed, the server can initiatively require the clients and return response message and the clients can carry out reorganization operation through identifiers in the response message. The safe and reliable communication method can guarantee safety and stability of data exchange between the Beidou operation center and the branch centers. Furthermore, the safe and reliable communication method has good expandability.
Description
Technical field
The present invention relates to a kind of Big Dipper operation centre and the safe and reliable method of communicating by letter in branch center.
Background technology
Along with a large amount of development of the business at Beidou satellite navigation application service center (be called for short: Big Dipper operation centre), produce the business demand of setting up Beidou satellite navigation application service operation branch center (being called for short: branch center) in individual area, owing to not occurring similar demand and application before this, therefore need to define the communication interface between a set of Big Dipper operation centre and branch center, to ensure the safety and stability of exchanges data between the two, the business completing between Big Dipper operation centre and its user is carried out and the demands such as user management, meet safety simultaneously, communication, the requirement of charging etc.
