Embodiment 1

[0030] Embodiment one: the device of mobile satellite mobile communication gateway station

[0031] The structure of the gateway station device in this embodiment is as follows image 3 As shown, it includes antenna module, satellite communication transceiver module, ground relay access module and integrated control module. The description of each module is as follows:

[0032] The antenna module adopts a high-gain antenna, which can be a small-diameter parabolic antenna or an array antenna;

[0033] The satellite communication transceiver module is responsible for communicating with the satellite through the user link through the antenna module, and only forwards the data packet without parsing. As a data link forwarding module, it does not need the application layer protocol stack, so only from the protocol stack Including physical layer and data link layer;

[0034] The ground relay access module uses broadband wireless access to access the wireless broadband base station...

Embodiment 2

[0040] Embodiment 2: Implementation method of mobile satellite mobile communication gateway station

[0041] The gateway station of the present embodiment adopts the gateway station device of Embodiment 1, and the intercommunication service between the satellite mobile communication terminal and the ground cellular mobile communication network is taken as an example below to specifically illustrate its implementation steps:

[0042] (1) After the gateway station is opened, the satellite communication transceiver module starts, searches for satellite signals and synchronizes, and sends a registration message to the satellite. The message carries the device ID number and device type of the satellite communication transceiver module, such as Figure 4 shown;

[0043] (2) The satellite receives the registration message, parses out the device ID number, and compares it with the locally stored device ID number (which needs to be configured to the satellite in advance). Close statio...

Abstract

The invention proposes a method for realizing a mobile satellite mobile communication gateway station, the method comprising: the air interface link between the gateway station and the satellite communication uses the user link of the satellite mobile communication system, and the gateway station uses a broadband wireless access method Access to the ground core network; after the gateway station is started, it initiates a registration process with the satellite and the ground core network. After the satellite registration is successful, the satellite will recognize it as the gateway station backhaul device; for the satellite downlink, the satellite will need to forward the The data packet is sent to the gateway station through the user link, and the gateway station forwards the data packet to the ground core network through the wireless broadband base station; for the satellite uplink, the ground core network transmits the data packet that needs to be forwarded through the wireless broadband base station Send to the gateway station, and the gateway station forwards the data packet to the satellite through the user link. The invention also proposes a device for a mobile satellite mobile communication gateway station.

Description

technical field [0001] The invention relates to the field of satellite mobile communication, in particular to a method and device for realizing a mobile satellite mobile communication gateway station. Background technique [0002] Satellite mobile communication is a way of communicating with the help of satellite links. Users can move freely within the coverage of satellite beams and maintain communication with ground communication systems and dedicated system users or other satellite mobile users. Compared with other communication methods, satellite mobile communication has the advantages of large coverage area, long communication distance, flexible communication, stable and reliable lines, etc. The satellite mobile communication system is suitable for both civil communication and private network communication. [0003] The network structure of the traditional satellite mobile communication system is as follows: figure 1 As shown, it is divided into user segment, ground s...
