Kind Code:
A1
Abstract:
A space-air-ground network service migration method, comprising: acquiring orbit planning information, performing simulation calculation on a satellite according to the orbit planning information, generating a migration trigger condition table, and when determining to trigger service migration according to orbit position information or orbit time information included in current orbit information and the migration trigger condition table, a service network element sending a service migration request which carries information of a migration data amount to a migration network element; and the migration network element determining, according to the information of the migration data amount and state information of the migration network element, information such as the number of migration times, a migration time, and a data amount to be migrated each time, and then performing data migration. By means of the method, normal use of a user service can be ensured when a network element in a space-air-ground network moves at a high speed.
