Embodiment Construction

[0042] Below in conjunction with accompanying drawing, the present invention will be further described:

[0043] figure 1 It is a schematic diagram of the message structure of the heartbeat message sent by the user machine provided by the technology of the present invention, and the heartbeat message includes two parts, a synchronization header and a service segment. The synchronization head is used by the ground central station to capture and track the inbound heartbeat signal, and the service segment message contains the user address (used to indicate the identity of the user), and the service beam (used for active positioning of the user machine).

[0044] figure 2 It is a schematic diagram of the workflow of sending a heartbeat message from a user machine provided by the technology of the present invention, including the following functions:

[0045] Whether the user machine sends a heartbeat message is jointly determined by whether the heartbeat message timer unit of t...

Abstract

The invention relates to a satellite mobile communication system heartbeat message realization system and method, the system comprises a ground control center and an user machine, wherein the ground control center can configure control parameters corresponding to inbound heartbeat message for the user machine, according to the received heartbeat message, user geographic position and transmitted power adjustment amount are calculated, state of user machine is updated, and results / a result of configured heartbeat message control parameters and / or user position and / or transmitted power adjustment amount calculated according to the heartbeat message are / is transmitted to the user machine; and the user machine receives heartbeat message control parameters configured by the ground control center and transmits the heartbeat message according to heartbeat message transmission unit instruction. The ground control center can quickly receive user position in real time, transmit power and state information through the user machine transmitting the inbound heartbeat message; the ground control center can ensure a certain power control accuracy and reduce cost of heartbeat signaling; and battery life and battery endurance can be improved because of short heartbeat message.

Description

technical field [0001] The invention relates to the technical field of satellite mobile communication, and more specifically, to a method for realizing heartbeat messages of satellite mobile communication. Background technique [0002] The satellite mobile communication system is mainly composed of the space segment, the ground control center and the user segment. The space segment is composed of a satellite constellation containing several satellites. These satellites (outbound transponder, inbound transponder) forward Outbound signals and inbound signals from user machines. The ground control center completes user signal transmission and reception measurement and information transmission and reception processing, and manages and controls the operation of the entire system. The user segment refers to the user terminal with the function of sending and receiving satellite signals, which receives data services and control messages from the ground control center, and sends inb...
