Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If user data profiles are provisioned to satellites in advance before they reach a specific region, then connectivity continuity and latency are improved, but the complexity of the provisioning system increases
Solution Approach 1:
The patent implements preliminary action by provisioning user data profiles to satellites and gateways in advance before they reach a specific service region. The system determines which satellites will service which regions based on orbital trajectories, and pre-provisions the necessary user profiles to the appropriate satellites or gateways before the satellites arrive at their service positions. This eliminates the need for real-time profile retrieval during satellite passes, thereby reducing latency and ensuring continuous connectivity.
2Reliability
If a centralized communication server manages all user data profiles, then data consistency and network control are improved, but the provisioning process becomes more complex
Solution Approach 1:
The patent applies segmentation by dividing the centralized user data profile storage into distributed cache copies located at multiple gateways across the network. Each gateway maintains a local cache of user profiles that it may need to service, rather than requiring all gateways to directly access the centralized server. This segmentation reduces the provisioning complexity by allowing gateways to operate independently with local data, while the centralized server maintains the master copy for consistency.
Solution Approach 2:
The patent introduces an intermediary mechanism where gateways act as intermediate storage nodes between the centralized communication server and the satellites. The gateways receive and cache user profiles from the centralized server, then provide them to satellites as needed. This intermediary approach simplifies the overall provisioning process by distributing the data delivery function across multiple gateways, reducing the direct provisioning burden on the centralized server while maintaining data consistency.
3Adaptability or versatility
If satellites continuously move to serve different regions, then geographic coverage and network versatility are improved, but data provisioning becomes more difficult
Solution Approach 1:
The patent implements preliminary action by pre-positioning user data profiles on satellites before they reach their service regions. The system determines the orbital trajectories of satellites and identifies which user profiles will be needed in which geographic regions. User profiles are then provisioned to the appropriate satellites in advance of their arrival at service positions, ensuring that moving satellites have the necessary data without requiring complex real-time provisioning during their continuous movement.
Solution Approach 2:
The patent applies dynamics by making the provisioning system adaptive to the dynamic orbital movements of satellites. The system continuously tracks satellite positions and trajectories, dynamically determining which gateways should provision data to which satellites based on their upcoming service regions. This dynamic approach allows the system to efficiently handle satellite movement while maintaining simplified provisioning through automated trajectory-based allocation.
Data Source
AI summary
The disclosed technology is generally directed to a method for provisioning data in a fifth generation (5G) communication network. In one example of the technology, the method may include storing user data profiles associated with the 5G communication network in a centralized communication server, determining a satellite that provisions 5G communication network over a region on the Earth during a time interval, and identifying a set of user equipment (UE) in the region. The method may include retrieving a set of user data profiles corresponding to the set of UE from the centralized communication server and determining a gateway that is in communication with the satellite. The method may include provisioning the set of user data profiles from the centralized communication server to the satellite via the gateway before the satellite reaches the region, thereby enabling the satellite to provision the 5G communication network to the set of UE.
