Problems solved by technology

However, this system also has certain disadvantages: when the signaling double-hop is converted to voice single-hop, the satellite cannot obtain the user information of the calling party and the called party, and the user information is stored in the core network of the ground mobile network
The control method of this scheme is relatively complicated, and the processing process is complicated

Abstract

The invention discloses a satellite communication system user information matching method led by a satellite route controller, which belongs to the technical field of satellite communication. A satellite communication system comprises a communication network main body branch and an on-satellite exchange processing unit management control branch, wherein the on-satellite exchange processing unit management control branch comprises the satellite route controller and a satellite control node. The method comprises the following steps that: i, a wireless network controller of a calling party transmits a calling / called identification code of the calling to the satellite route controller; ii, the wireless network controller of the calling party transmits user information of the calling party to the satellite route controller; iii; a wireless network controller of a called party reports user information of the called party to the satellite route controller; and iv, the satellite route controller matches the user information of the calling party and the user information of the called party into a corresponding call connection calling / called pair according to the calling / called identification code. The method can be used for satellite mobile communication.

Description

technical field [0001] The invention relates to a satellite mobile communication system, in particular to a user information matching method in a single-hop mode of the satellite mobile communication system, and belongs to the technical field of satellite communication. Background technique [0002] The terrestrial cellular mobile communication system has developed rapidly in the past 20 years. It has experienced 2G, 2.5G and 3G, and is currently advancing rapidly to 4G. Among them, the typical standards belonging to 2G include GSM and IS-95CDMA, etc., the typical standards of 2.5G are GPRS and EDGE, etc., and the typical technical standards of 3G are WCDMA, CDMA2000 and TD-SCDMA respectively. [0003] The satellite communication system has many unique advantages, such as: it can cover a large and sparsely populated area without adding expensive costs; it can provide services for users on the sea and on the plane; it can share the communication traffic of the ground network ...
