Embodiment Construction

[0033] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. Note: The specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0034] In the embodiment, the matching method is coordinated by a mobile switching center (MSC SERVER), a satellite routing controller (SRC) and a radio network controller (GNC). The overall design of the communication network utilizes the existing ground communication network, and on this basis, an on-board switching management and control branch is added. This embodiment is based on the 3G compatible system (specifically, based on the 3GPP / UMTS Release 4 reference model [3rd GPP Technical Specification Group Services and Systems Aspects: Network architecture, Release 4, 3GPP TS 23.002 V4.8.0, 2003-06]).

Abstract

The invention discloses a user information matching method for a satellite mobile communication system and belongs to the technical field of satellite communication. The communication system comprises a communication network main branch and a satellite switch management control branch, wherein the satellite switch management control branch comprises a satellite routing controller and a satellite control node which are in data connection; the satellite routing controller is in data connection with a radio network controller and a mobile switching center; and the satellite control node is in data connection with satellites. The method comprises the following steps that: 1) the mobile switching center sends caller / called position information of the call to the satellite routing controller; 2) the satellite routing controller establishes a user information table of the call and requests the radio network controller to which the caller / called parties belong for user link channel information of the caller / called parties according to the user information table; and 3) the satellite routing controller analyzes and determines a switching router and sends the determined results to the satellites through the satellite control node. The user information matching 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 matching method for exchanging caller / called user information on a satellite. It belongs to the technical field of satellite communication. Background technique [0002] Since Guglielmo Marconi invented wireless communication in 1897, new wireless and wired communication methods, services and standards have been continuously adopted by operators all over the world. This evolution process is constantly accelerating, especially in the past ten years, the mobile wireless industry has developed rapidly under the stimulation of many new technologies. The exponential growth in mobile wireless communications is expected to continue in the coming decades. There are many existing wireless communication systems, for example, the Advanced Mobile Phone Service cellular system (AMPS) in the United States, the Nordic Mobile Telephone system (NMT) in North America, and the Global S...
