Embodiment 1

[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...

Embodiment 2

[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...

Abstract

The invention discloses a signaling processing method and a signaling processing system for a satellite communication network with satellite switch capability. The system comprises a satellite part and a ground part, wherein the satellite part comprises a signaling packet identification sorting module, a portal signaling notification module, a satellite signaling processing module, a satellite forwarding table, connection table and resource table management module, and an export signaling notification module; and the ground part comprises a signaling and control information interface, a ground signaling processing module, and a ground forwarding table, connection table and resource table management module. The processing method comprises a signaling sorting step, a signaling processing step and a satellite-ground synchronization step. Signaling information is processed by adopting the concept of coordinate between satellite and ground, and compared with a ground signaling processing delay, a satellite signaling processing delay is remarkably shortened; and a satellite computation capability is fully utilized, rapid and timely connection establishment service is provided for a high-priority service, and the function of the conventional ground control center also can be fully developed to overcome the shortcoming of limitation of satellite computation incapability on the arrival rate of a call.

Description

technical field [0001] The invention relates to a signaling processing method in a satellite communication network with on-board switching capability, and belongs to the technical field of communication. Background technique [0002] Satellite communication technology has now entered the era of on-board exchange, that is, user information is forwarded on satellites. However, limited to the processor technology that can be used on the satellite, it is more difficult, and the signaling used to establish the connection between the two parties still needs to be processed in the ground control center. The usual processing process is as follows: when the ground user initiates a call and the signaling packet is transmitted to the satellite, the satellite port processing module identifies it, detects the signaling packet, and forwards the signaling packet through the dedicated control beam directly with the ground control center To the control center, the signaling processing modul...
