Satellite communication adaptive position management method oriented to typical movement characteristics

Abstract

The invention discloses a typical movement characteristic-oriented satellite communication adaptive position management method, which comprises the following steps of: constructing, updating and continuously monitoring a movement track list by a mobile user, and judging whether the mobile user enters a reciprocating state or a usual track state or not; the mobile user sends a reciprocating beam / usual track binding request to the gateway station; the gateway station binds a wave beam contained in the request information with the mobile user, and sends binding confirmation information to the mobile user; after the mobile user receives the binding confirmation information, the mobile user does not send the position updating request in the binding beam; when the mobile user enters a beam except the bound beam, a beam unbinding request is sent to the gateway station; and the gateway station releases beam binding of the mobile user and sends unbinding confirmation information. The invention provides a position management method adaptive to state movement characteristics for two typical movement states of reciprocating and usual trajectory of a mobile user, and can effectively reduce the resource overhead of position updating.

Description

technical field [0001] The invention relates to satellite mobile communication technology, in particular to a satellite communication self-adaptive position management method oriented to typical mobile characteristics. Background technique [0002] Location management technology is the key technology of network mobility management in satellite mobile communication system, which affects the performance and operation cost of the whole system. Location management consists of two processes, location update and system paging. When the mobile ground station passes through different beam coverage areas or enters the registration area, it reports its own position to the system through position update, so that the system can track the dynamic changes of the user's position; when a call arrives, the system obtains the user's current location through paging Location information to enable the system to deliver calls to mobile users. [0003] In the satellite mobile communication syste...

Problems solved by technology

[0004] Aiming at the problem that the location management overhead of the multi-beam satellite mobile communication system is large, the invention discloses a typical mobile characteristic-oriented satellite communication system adaptive location management method. The satellite communication system consists of multi-beam satellites, ground gateway stations and ground Composed of mobile users, in the process of crossing different beam coverage areas, ground mobile users update their location according to the location management method and inform the gateway station of their own beam. The specific steps are:
