Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional wireless communication systems face inefficiencies in paging configuration, leading to suboptimal performance for UEs with varying demands and channel conditions, resulting in increased network resource usage and false paging issues, especially when multiple beams are employed.
Innovation Solution
A method for dynamically updating paging configurations based on real-time paging conditions, such as false paging rate, latency, and PDCCH load, by adjusting parameters like the number of Page Frames, Paging Occasions, and radio beams, to optimize DRX operation and minimize network resource consumption.

Engineering Contradiction Analysis
1Device complexity
If a common static paging configuration is used for all UEs, then network resource usage is simplified and management is easier, but performance is suboptimal for UEs with varying demands and channel conditions
Solution Approach 1:
The patent implements dynamic paging configuration where the network node adjusts paging parameters (DRX cycle length, number of POs per frame, number of beams) based on real-time UE behavior patterns, channel conditions, and network load. This transforms the static configuration into a dynamic adaptive system that optimizes performance for different UE types and conditions.
Solution Approach 2:
The patent applies different paging configurations to different UEs or UE groups based on their specific characteristics. Each UE can have customized paging parameters tailored to its mobility pattern, service requirements, and channel conditions, rather than using a uniform configuration for all UEs.
2Productivity
If multiple POs are configured per frame to handle high paging load, then paging capacity increases, but false paging rate increases and network resources are consumed
Solution Approach 1:
The patent employs feedback mechanisms where the network node monitors UE paging response behavior and channel conditions, then adjusts the number of POs and beam configurations accordingly. When false paging is detected or channel conditions deteriorate, the system adapts by modifying PO distribution and beam sweeping patterns to reduce false paging events.
Solution Approach 2:
The patent dynamically changes paging parameters including DRX cycle length, number of POs per frame, and beam sweeping configuration based on observed UE behavior and network conditions. These parameter adjustments optimize the balance between paging capacity and false paging reduction.
3Reliability
If beam sweeping is used to cover all directions, then coverage is improved, but paging latency increases and energy consumption increases
Solution Approach 1:
The patent segments the beam sweeping process by dividing the cell coverage into multiple sectors or directional groups, and configures different POs for different beam directions. This allows UEs to monitor only relevant beams for their location, reducing the effective sweeping time and latency while maintaining comprehensive coverage.
Solution Approach 2:
The patent implements periodic beam sweeping patterns where beams are transmitted in a repeating sequence across different directions. By optimizing the periodicity and duration of each beam transmission, the system achieves comprehensive coverage while minimizing the time UEs need to wait for their designated beam, thus reducing paging latency.
4Use of energy by moving object
If DRX cycle length is increased to reduce UE energy consumption, then idle mode energy saving improves, but paging latency increases
Solution Approach 1:
The patent dynamically adjusts the DRX cycle length based on UE activity patterns, mobility conditions, and network paging load. For UEs with low activity or stable conditions, longer DRX cycles reduce energy consumption. For UEs requiring faster response or experiencing high mobility, the system shortens the DRX cycle to reduce latency, creating an adaptive balance between energy saving and responsiveness.

AI summary
The present disclosure relates to telecommunications. In one of its aspects, the disclosure concerns a method in a Radio Access Network (RAN) node for updating a paging configuration for at least one User Equipment (UE) in a wireless communications system. The RAN node uses at least one radio beam for transmitting at least one paging message to said UE(s). The method comprises obtaining information regarding at least one paging condition. The at least one paging condition is associated with a current paging configuration for said at least one UE and comprises at least one of a false paging rate, latency, PDCCH load, and PDCCH and PDSCH imbalance. The method further comprises determining whether the obtained information regarding the at least one paging condition exceeds a respective associated threshold; and updating, based on the determination, the current paging configuration into an updated paging configuration for said at least one UE. Updating the current paging configuration comprises adjusting one or more configurations of the one or more radio beams for transmitting a paging message to said at least one UE.
