Embodiment 1

[0030] Embodiment 1: The device of mobile satellite mobile communication gateway

[0031] The structure of the gateway station device of 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-aperture parabolic antenna or an array antenna, etc.;

[0033] The satellite communication transceiver module is responsible for communicating with the satellite using the user link through the antenna module, and only forwards data packets without parsing processing. As a data link forwarding module, it does not require 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 connect to the wireless broadband base station,...

Embodiment 2

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

[0041] The gateway station of this embodiment adopts the gateway station device of the first embodiment. The following takes a satellite mobile communication terminal and a terrestrial cellular mobile communication network as an example to illustrate the implementation steps:

[0042] (1) After the gateway is turned on, 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 the device ID number, and compares it with the locally stored device ID number (which needs to be configured to the satellite in advance). If they are consistent, the registration is returned and the satellite communication tr...

Abstract

The invention provides a realization method and a device for an action-based satellite mobile communication gateway station. The realization method comprises: air interface link of the gateway station for communicating with the satellite uses a user link of a satellite mobile communication system, and the gateway station accesses a ground core network through a broadband wireless access mode; the gateway station initiates a registration process to the satellite and the ground core network after starting up and the satellite identifies the gateway station as a gateway station backhaul device after the registration of the satellite is succeeded; for the downlink of the satellite, the satellite transmits the data pack which is needed to be transponded to the gateway station through the user link; the base station transponds the data pack to the ground core network through the wireless broadband base station; for the satellite uplink, the ground core networks transmits the data pack which is needed to be transponded to the gateway through the wireless broadband base station; and the gateway station transponds the data pack to the satellite through the user link. The invention also provides an action-based satellite mobile communication gateway station device.

Description

Technical field [0001] The present invention relates to the field of satellite mobile communications, in particular to a method and device for implementing a mobile satellite mobile communications gateway. Background technique [0002] Satellite mobile communication is a way of communicating by means of satellite links. Users can move freely within the coverage of satellite beams and maintain communication with ground communication system 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, and stable and reliable lines. The satellite mobile communication system is suitable for both civil communication and private network communication. [0003] Traditional satellite mobile communication system network structure such as figure 1 As shown, it is divided into user segment, ground segment and space segment. T...
