Engineering Contradiction Analysis
1Reliability
If satellite networks maintain continuous connection with numerous mobile wireless devices, then connection reliability is improved, but frequency spectrum consumption increases
Solution Approach 1:
The core network performs preliminary actions by maintaining parameter lists with location and satellite estimates, and calculating connection probabilities in advance. This allows the network to proactively determine which base stations are likely to serve mobile devices before actual connection is needed, enabling efficient resource allocation and reducing continuous spectrum consumption while maintaining connection reliability.
2Area of stationary object
If satellite networks manage connections with mobile devices using traditional methods, then connection coverage is maintained, but spectral resource efficiency deteriorates
Solution Approach 1:
The system dynamically adapts to changing conditions by continuously updating parameter lists with current location estimates and satellite positions. The connection probability calculations are dynamically adjusted based on real-time parameters, allowing the network to optimize spectral resource allocation as mobile devices move and satellite coverage areas change, thereby maintaining coverage while improving efficiency.
Solution Approach 2:
The core network changes key parameters including location estimates, satellite position estimates, and connection probabilities based on updated information. By monitoring and adjusting these parameters, the system can determine the most efficient base station mappings dynamically, ensuring coverage is maintained while spectral resources are used more efficiently.
3Measurement precision
If the core network calculates connection probabilities for all wireless devices, then connection management accuracy is improved, but computational complexity increases
Solution Approach 1:
The system segments the large-scale satellite network into smaller manageable units by maintaining separate parameter lists for different base stations and their associated mobile devices. This segmentation allows probability calculations to be performed on smaller subsets of data rather than all devices simultaneously, reducing computational complexity while maintaining accuracy through localized probability assessments.

AI summary
Apparatuses, methods, and systems for managing a connection of a wireless device to a satellite network are disclosed. One method includes maintaining, by a core network of the satellite network, a parameter list that includes at least an estimate of a location of the wireless device and an estimate of one or more satellite locations, estimating, by the core network, a probability of a mapping of a wireless connection between the wireless device and a base station supporting the satellite network based upon the parameter list, and initiating, by the core network, a procedure to communicate with the wireless device through the base station based on the estimated probability of the mapping of the wireless connection between the wireless device and the base station.
