First, embodiments of the present disclosure provide a service migration method for air-to-air and ground networks, which can be executed by any electronic device with computing processing capabilities.

Figure 1 shows a flow chart of a service migration method for an air-to-air network in an embodiment of the present disclosure. As shown in Figure 1, the service migration method for an air-to-ground network provided in an embodiment of the present disclosure includes the following steps:

S102: The service network element determines whether to trigger service migration based on the current track information and the migration trigger condition table.

In one embodiment, the migration trigger condition table includes but is not limited to: migration time, migration location, migration target or time when the satellite leaves the service coverage area.

It should be noted that the migration time is the time it takes for satellites to be simulated and calculated to predict the need for migration services based on orbit planning information.

It should be noted that the migration location is the location where the satellite needs to be relocated based on the orbit planning information and is simulated and calculated to predict the location.

It should be noted that the migration target is the network element that can provide migration services.

In one embodiment, the current orbit information includes but is not limited to: orbit position information or orbit time information.

In one embodiment, orbital parameters include, but are not limited to: orbital speed, period, or equator angle.

In one embodiment, current orbit position information or orbit time information is obtained to satisfy the migration triggering condition When the information in the table is obtained, the migration service is triggered. For example, the current orbit position information is obtained. When the current orbit position information is the migration position in the migration trigger condition table, the migration service is triggered.

S104, if so, the service network element sends a service migration request to the target migration network element so that the target migration network element can provide services, where the target migration network element is a migration network element that can provide migration services.

In one embodiment, the serving network element and the migration network element are air-space network elements.

For example, the satellite 1 service network element provides services for user terminals in service area A, and the satellite 2 service network element provides services for service area B user terminals; during migration, the satellite 1 service network element provides services for service area A user terminals; relative to satellite 1 , the satellite 2 service network element becomes the migration network element, providing services to service areas A and B at the same time.

In the above embodiment, for network element track mobility, the certainty of the track is utilized, and a migration trigger condition table is used to implement migration triggering. When the serving network element is about to move out of the covered service area, it will be communicated with the subsequent target migration network element. Interaction enables the target migration network element to take over the service network element mechanism, thereby ensuring continuous user access and business applications.

When the migration network element can provide migration services, the migration network element is determined as the target migration network element.

S208: The target migration network element determines migration information based on the migration data volume information and the status information of the target migration network element.

Among them, the migration information includes: the number of migrations, migration time, migration track, and the amount of data migrated each time.

In one embodiment, it is determined whether the amount of migrated data exceeds a threshold. If not, one migration is negotiated; if so, multiple migrations are negotiated.

It should be noted that when negotiating a migration, it is necessary to determine the migration time and the amount of data to be migrated.

It should be noted that when negotiating multiple migrations, the migration time, migration data volume, and migration times need to be determined; the target migration network element migrates data based on the migration information; the target migration network element can then migrate data to one or more migration network element.

Multiple migrations are suitable for service network elements that have a large amount of data to be migrated, or the current processing capabilities of the migrating network element are insufficient. Subsequent migration of data to other satellites will be done by itself until the processing capabilities are restored. The target migration network element will be migrated based on the migration data volume information and target migration The status information of the network element determines the migration information, which can efficiently process the migration data.

User terminals provide services.

For example, before migration, the satellite 1 service network element provides services for user terminals in service area A, and the satellite 2 service network element provides services for user terminals in service area B. During data migration and backup, the satellite 1 service network element provides services for user terminals in service area A.

In the above embodiment, the target migration network element has sufficient resources and is in good operating status. In response to the migration request, it is judged that the migration data is small, and a one-time migration can be provided. If it is judged that the migration data is large, multiple migrations can be provided, and a migration time or time is agreed upon. The track position can save resources and implement a mechanism for target migration network elements to undertake service network elements, thereby achieving continuous services for users.

S306: The service network element deletes the data of the user terminal in the original service area.

For example, before the migration, the satellite 1 service network element provides services for user terminals in service area A, and the satellite 2 service network element provides services for user terminals in service area B; after data migration and backup, the satellite 1 service network element no longer serves users in area A. The terminal provides services, the satellite 2 service network element provides services for service area A user terminals, and the satellite 1 service network element deletes data related to service area A user terminals.
