Embodiment Construction

[0016] The technical solutions of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0017] A low-orbit satellite communication paging method based on ground planning routing area, which is applied to figure 1 The application scenario of the low-orbit satellite mobile communication system shown. The scenario includes satellite mobile terminals, low-orbit satellites, and gateways. The low-orbit satellites are transparently forwarded, and the routing area update process between the terminal and the gateway is forwarded through the low-orbit satellites.

[0018] The specific process of this method is as figure 2 shown, including the following steps:

[0019] (1) Carry out routing area division based on ground planning. The specific division rules are not limited. It can be divided and numbered according to the administrative area of ​​the city, or divided and numbered according to the longi...

Abstract

The invention discloses a low-orbit satellite communication paging method based on a ground planning routing area, and belongs to the technical field of low-orbit satellite mobile communication. According to the method, a system routing area is planned based on a ground area in the low-orbit satellite mobile communication system and is mapped to a satellite link for paging through a routing area number, and the problem of huge signaling overhead caused by frequent routing area updating of the low-orbit satellite mobile communication system is solved. The invention can be applied to the mobility management process of the low-orbit satellite mobile communication system, the system routing area updating process can be effectively optimized, the air interface load is reduced, and the air interface resource utilization rate is obviously increased.

Description

technical field [0001] The invention relates to a low-orbit satellite communication paging method based on a ground-planned routing area, and belongs to the technical field of low-orbit satellite mobile communication. Background technique [0002] In the low-orbit satellite mobile communication system, the satellite moves at high speed along the predetermined orbit. Even if the satellite terminal remains stationary, frequent switching between the satellite and the terminal will occur, that is, the beam where the terminal resides is frequently switched. [0003] According to the traditional mobility management process, the routing area planning is bound to the beam. When the beam where the terminal resides changes, the routing area changes, and the terminal initiates the routing area update process. If the mobility management of the low-orbit satellite mobile communication system refers to the traditional processing method, the terminal will perform the routing area update pr...
