Signaling processing method and system for satellite communication network with satellite switch capability

[0046] Without loss of generality, the following description takes the on-board ATM switching system as an example, and its on-board signaling system can use two signaling formats: single-cell signaling and multi-cell signaling. The single cell format is a simplified ATM signaling, which limits the signaling packet of a message to be transmitted in one cell (the length of the ATM switching cell packet on the star is not limited to 53 bytes). At the same time, it is required to add a delay and priority option in the signaling cell format, and the user fills in according to the delay and priority requirements when sending. The length of the multi-cell format signaling packet is not limited, and the message is divided and carried by multiple signaling cells through the signaling adaptation mechanism. refer to figure 1 For multi-cell signaling cell structure, the cell format of the present invention should include message category (SETUP, CALL PROCEEDING, CONNECT, CONNECT ACK, AL...

[0072] In this embodiment, the actual situation of communication between users is taken as an example to illustrate the idea of ​​the present invention. Firstly, a connection is established by using a signaling system. If there are multiple calls, multiple signalings are used for connection. In this embodiment, two signalings are used for description. When the two signalings arrive at the satellite signaling packet identification and sorting module, the module directly checks the message type and delay identifier of the signaling cell format, and at the same time judges the satellite or ground processing according to the load of the satellite processor. If on-board processing is performed, the signaling is forwarded to the satellite signaling processing module; when ground processing is performed, the signaling is forwarded to the ground signaling processing equipment. Figure 4 and 5 They are the connection establishment and release process respectively. The process is desc...
