DISTRIBUTED MANAGEMENT OF LEO SATELLITE NETWORKS WITH MANAGEMENT AGILITY AND NETWORK EFFICIENCY
First Claim
1. A method for a distributed management arrangement for LEO satellite networks, including a Network Operations Center (NOC), a plurality of distributed management centers (DMC) and a plurality satellites, comprising:
- the NOC determining, prior to launch, the satellites under the management jurisdiction of each DMC, and providing this information to the satellites and DMCs;
the NOC uploading configuration information to satellites and receiving status and performance information from satellites via the respective DMCs;
each DMC exchanging routine management information with associated satellites at fixed times only via an uplink and a downlink; and
a DMC nearest to a satellite exchanging time sensitive information with the respective satellite at the time instant at which the information is needed.

Abstract
In a distributed management scheme for LEO satellite networks interactions between a satellite and the designated fixed center occur according to a time schedule and only when the designated center is in the coverage area of the payload. For exception/alarm reporting and real-time configuration updates the interaction varies with time. Interactions of this type occur between a satellite and the management center that is “nearest” to the payload or satellite at the time instant at which the network event occurs or configuration upload is needed. The nearest management center for a payload is the center that can be reached from the payload with fewest number of crosslink hops. A central network operation center determines, prior to payload launch, the association between satellites and management centers for routine information exchange, and the nearest management center for the payload for different snapshots of time.

9. A system for a distributed management arrangement for LEO satellite networks comprising:
-
a network of satellites; a network operations center (NOC) for determining before launch the associations between satellites and DMCs for routine management information exchange, and the nearest DMC that can be reached from each satellite for different time instants; and a plurality of distributed management centers (DMC) in information receiving relationship with the network operations center and associated with respective satellites at different time instants; wherein a DMC exchanges routine management information with associated satellites at fixed times based on information received from the NOC; and the DMC nearest to a respective satellite exchanging time sensitive information with the respective satellite at the time instant at which the information is needed.
