5G UE Capability Control via Base Station Mediation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In 5G mobile communication systems, User Equipment (UE) may encounter interference or issues like overheating and battery over-consumption, necessitating the ability to temporarily change its capability to alleviate these problems, but autonomous UE capability modification can lead to instability and additional signaling load, requiring network-controlled UE capability management.
Innovation Solution
A method and apparatus where a base station sends UE capability configuration information to a terminal, indicating whether it can request restricted UE capability, and responds to such requests, using broadcast or dedicated signaling to manage the UE capability, ensuring transparency to the 5G core network and maintaining device stability.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If the UE autonomously changes its capability to alleviate problems like interference or overheating, then the UE can adapt to adverse conditions, but the network stability deteriorates and signaling load increases
Solution Approach 1:
The network side acts as an intermediary by introducing a configuration parameter that controls whether the UE can autonomously change its capability. The UE sends a capability change request to the network, and the network decides whether to approve the change based on current network conditions, thus mediating between UE adaptability needs and network stability requirements
Solution Approach 2:
The network provides feedback to the UE through the configuration parameter indicating whether autonomous capability change is permitted. This feedback mechanism allows the network to control UE behavior based on overall system state, preventing uncoordinated capability changes that could destabilize the network
2Speed
If the UE autonomously changes its capability, then the UE can respond to adverse conditions quickly, but the signaling load increases
Solution Approach 1:
Instead of allowing complete autonomous capability change or requiring full network coordination for every change, the patent implements a partial action approach where the UE can quickly indicate its need for capability change through a simplified request mechanism, and the network applies selective control through the configuration parameter, reducing unnecessary signaling while maintaining essential control
3Reliability
If the network controls UE capability changes, then the network stability is maintained, but the UE adaptability to adverse conditions is reduced
Solution Approach 1:
The system dynamically adjusts the level of UE autonomy through the configuration parameter. When network conditions are stable, the network can permit greater UE adaptability by allowing autonomous capability changes. When network conditions require stricter control, the network can restrict UE capability changes. This dynamic control mechanism balances network stability with UE adaptability based on real-time conditions

AI summary
Disclosed in the present invention are a method and apparatus for controlling a restricted UE capability, and a computer storage medium. The method comprises: a base station sends UE capability configuration information to a terminal, the UE capability configuration information being used for indicating whether the terminal can send, to the base station, a request message for using a restricted UE capability; and when the base station receives the request message for using a restricted UE capability, which is sent by the terminal, the base station sends, to the terminal, a reply message for confirming the use of the restricted UE capability.
