5G Cell Camping Control for NES-Capability-Based UE Barring
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G communication systems lack the ability to selectively bar UEs based on their network energy saving (NES) capability, leading to reduced communication efficiency and increased power consumption when cells enter energy-saving mode.
Innovation Solution
The system sends specific indication information to UEs, distinguishing between UEs with and without NES capability, allowing or barring camping based on their energy-saving status, using MIB and SIB1, and sending UE capability indication and access rejection messages.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of energy
If the cell enters energy-saving mode without distinguishing UE types, then network energy consumption is reduced, but communication efficiency deteriorates and power consumption of non-NES UEs increases
Solution Approach 1:
The patent segments UEs into two distinct types based on NES capability support: first type UEs (without NES capability) and second type UEs (with NES capability). This segmentation allows the network to apply different camping policies to different UE groups, enabling energy-saving operations for NES-capable devices while maintaining normal operations for non-NES devices, thus resolving the contradiction between network energy reduction and communication efficiency.
Solution Approach 2:
The patent applies local quality by implementing differential treatment for different UE types within the same cell. First type UEs are barred from camping in energy-saving mode cells, while second type UEs are allowed to camp. This localized quality differentiation ensures that energy-saving measures are applied only where appropriate (to NES-capable UEs) without negatively impacting non-NES UEs, thereby maintaining overall communication efficiency while achieving energy savings.
2Adaptability or versatility
If all UEs are allowed to camp in energy-saving mode cells, then camping flexibility is maintained, but power consumption of non-NES UEs increases
Solution Approach 1:
By segmenting UEs based on NES capability, the patent enables selective camping permissions. Second type UEs (NES-capable) maintain full camping flexibility in energy-saving mode cells, while first type UEs (non-NES) are barred from such cells. This segmentation preserves adaptability for capable devices while protecting non-capable devices from excessive power consumption.
Solution Approach 2:
The patent implements local quality by applying different camping policies to different UE types: second type UEs enjoy unrestricted camping access (high adaptability), while first type UEs are restricted from energy-saving mode cells (reducing their power consumption). This localized differentiation resolves the contradiction between maintaining overall camping flexibility and reducing individual UE power consumption.
3Measurement precision
If indication information is sent to all UEs, then camping control accuracy is improved, but device complexity increases
Solution Approach 1:
The patent segments indication information into two distinct types: first indication information for first type UEs and second indication information for second type UEs. This segmentation enables precise camping control tailored to each UE type's capabilities. The increased precision is achieved through targeted information delivery rather than blanket notifications, which helps manage device complexity by providing only relevant information to each UE type.
Solution Approach 2:
The patent applies local quality by customizing the indication information content and delivery method for different UE types. First type UEs receive first indication information with specific camping control instructions, while second type UEs receive second indication information with different instructions. This localized information quality improves camping control accuracy for each group while avoiding the complexity of universal complex protocols.
