Embodiment 1

[0039] figure 1 It is a flow chart of a network access authentication method for a satellite communication network provided by an embodiment of the present application.

[0040] Such as figure 1 As shown, the network access authentication method for the satellite communication network provided in this embodiment includes the following operations.

[0041] S101: Receive identity information of a satellite communication terminal.

[0042] When a satellite communication terminal makes a communication request, it first uploads its identity information to the central station through the satellite signaling channel of the communication satellite. The identity information includes user credentials, passwords, digital certificates, IP addresses, MAC addresses, device fingerprints, and local challenge strings. and other information, some of which can also be used as the identity information. Satellite communication terminals generally upload the identity information in encrypted or ...

Embodiment 2

[0052] figure 2 It is a flowchart of a network access authentication method for a satellite communication network provided by another embodiment of the present application.

[0053] Compared with the previous embodiment, the network access authentication method provided by this embodiment adds communication duration statistics and billing functions, so that the complete flow chart of the network access authentication method is as follows figure 2 shown.

[0054] S201: Receive identity information of a satellite communication terminal.

[0055] When a satellite communication terminal makes a communication request, it first uploads its identity information to the central station through the satellite signaling channel of the communication satellite. The identity information includes user credentials, passwords, digital certificates, IP addresses, MAC addresses, device fingerprints, and local challenge strings. and other information, some of which can also be used as the iden...

Embodiment 3

[0067] image 3 It is a schematic diagram of a network access authentication system for a satellite communication network provided by another embodiment of the present application.

[0068] Such as image 3 As shown, the satellite communication network access authentication system provided in this embodiment includes a data receiving device 10 , an identity authentication device 20 and a policy service device 30 arranged at a central station.

[0069] The data receiving device 10 is used for receiving the identity information of the satellite communication terminal.

[0070] When a satellite communication terminal makes a communication request, it first uploads its identity information to the central station through the satellite signaling channel of the communication satellite. The identity information includes user credentials, passwords, digital certificates, IP addresses, MAC addresses, device fingerprints, and local challenge strings. and other information, some of whic...

Abstract

The invention relates to a network access authentication method and system of a satellite communication network. The method includes the following steps that: identity information of a satellite communication terminal is received; the identity information is verified automatically; and after the satellite communication terminal is verified successfully, corresponding communication resources are allocated to the satellite communication terminal, so that the connection of the satellite communication terminal and a communication satellite is shifted to a satellite service channel from a satellite signaling channel, and therefore, the satellite communication terminal can carry out normal voice or data communication. With the network access authentication method adopted, manual intervention is not needed, and respond to a communication requirement transmitted by the satellite communication terminal can be automatically completed, and resource allocation can be performed according to authentication results. Compared with an existing network access authentication mechanism, the method of the invention has much higher efficiency and can better meet ever-increasing satellite communication demands.

Description

technical field [0001] The present application relates to the technical field of satellite communication, and more specifically, to a network access authentication method and system for a satellite communication network. Background technique [0002] The satellite communication network refers to the VSAT (Very Small Aperture Terminal) satellite communication system based on data communication and voice communication, which is mainly composed of a master station, communication satellites and satellite communication terminals. The satellite communication terminals here usually refer to portable stations deployed on the emergency command front, remote areas, drilling platforms, etc., and also include vehicle-mounted stations installed on mobile platforms such as aircrafts, drones, and vehicles; the main station refers to fixed satellites Communication ground station. The access control of all satellite communication terminals is uniformly dispatched by the satellite network ma...
