Description
Technical Field
The invention relates to a terminal position information interaction method, in particular to a terminal position information interaction method supporting a Tiantong coarse positioning function, and belongs to the technical field of satellite communication.
Background
In the space-time satellite mobile communication system, satellite signals are served in the form of spot beams covering the ground, and each satellite beam broadcasts the longitude and latitude information of the central point of the beam in a BCCH channel. When the communication terminal initiates a service (such as position updating, making a call or receiving a call, data service, receiving and sending a short message, and the like), the relative offset value calculated by the longitude and latitude of the terminal position and the longitude and latitude of the satellite beam central point is filled in a signaling, and the relative offset value is reported. After the network side receives the relative offset value from a certain beam, the position information of the terminal can be calculated by combining the longitude and latitude of the central point broadcasted by the beam, so that the rough positioning of the Tiantong terminal is realized.
Because the terminal service can be passively initiated (called service, short message receiving service and the like) or periodically initiated (periodic position update, beam switching process and the like), the service initiation time cannot be predicted in advance, and the terminal can not acquire the position information in time to influence reporting of coarse positioning information; when the terminal switches the beams, if the relative offset value is calculated by using the position center of the beam which is located before, the deviation of the position of the terminal calculated by the network end can be caused.
