Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current 4G/5G systems face challenges in implementing enhanced features and functionalities, particularly in network slicing, where existing technologies struggle to efficiently manage registration, connection, and quality of service (QoS) across diverse access networks, including terrestrial and non-terrestrial environments.
Innovation Solution
The implementation of advanced network functions such as Access and Mobility Management Function (AMF), Session Management Function (SMF), and User Plane Function (UPF) within the 5G core network, which enable enhanced registration management, connection management, and QoS control through advanced signaling protocols and network slicing mechanisms.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If mobile devices register with every base station in coverage area, then network coverage and connectivity are improved, but registration overhead and network congestion increase
Solution Approach 1:
The patent combines multiple base stations into a registration group where a single registration with the group representative base station substitutes for individual registrations with each base station. This merging approach maintains network connectivity across the group while significantly reducing registration overhead and signaling congestion.
Solution Approach 2:
The registration group representative base station serves multiple functions: it acts as the primary registration point for all devices in the group, maintains the registration group information, and coordinates with other base stations. This universal role reduces the need for separate registration mechanisms for each base station.
2Productivity
If registration group radius is large, then registration overhead is reduced, but registration accuracy and location precision deteriorate
Solution Approach 1:
The patent implements dynamic adjustment of the registration group radius based on device mobility patterns, service requirements, and network conditions. The radius can be expanded for stationary devices to reduce overhead, while contracted for mobile devices to maintain location accuracy. This dynamic parameter adjustment resolves the contradiction between registration efficiency and location precision.
Solution Approach 2:
The system changes the registration group radius parameter adaptively based on different scenarios, device types, and network conditions. By adjusting this key parameter, the system optimizes the balance between reducing registration overhead and maintaining sufficient location accuracy for various service requirements.

AI summary
A method can include sending, by a wireless device, a first registration request message comprising a first geographical coordinate of a first geographical location. The method can also include receiving, after the first registration request message, a registration accept message comprising a radius value. The method can further include moving, by the wireless device, to a second geographical location. The method can additionally include sending, based on a distance between the first geographical coordinate and a second geographical coordinate of the second geographical location being larger than the radius value, a second registration request message comprising the second geographical coordinate.
