Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks struggle to efficiently manage time-sensitive communications, as they lack effective mechanisms for configuring network functions and routing devices to meet stringent latency thresholds and quality of service requirements.
Innovation Solution
Implementing a Centralized User Configuration (CUC) and Centralized Network Configuration (CNC) to configure network functions and routing devices, along with a Network Data Analytics Function (NWDAF) to monitor and aggregate analytics for time-sensitive communications, using interfaces to facilitate real-time adjustments and optimizations.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If wireless networks use existing configuration mechanisms, then device complexity is reduced, but the ability to meet time-sensitive communication latency thresholds deteriorates
Solution Approach 1:
The system segments configuration management into separate centralized functions: CUC for user-side configuration and CNC for network-side configuration. This segmentation allows each function to be optimized independently, with CUC handling user-specific time-sensitive parameters and CNC managing network infrastructure settings, thereby achieving reliable latency compliance without overwhelming complexity in a single monolithic system
Solution Approach 2:
The patent introduces CUC and CNC as intermediary configuration entities between the analytics function and network elements. These intermediaries receive analytics data, process configuration decisions, and translate them into actionable configuration parameters for network functions and routing devices, thereby simplifying the overall system architecture while enabling precise time-sensitive communication management
2Productivity
If real-time monitoring and configuration adjustments are implemented, then time-sensitive communication performance is improved, but system complexity increases
Solution Approach 1:
The system establishes a feedback loop where the analytics function continuously monitors network performance metrics, compares them against time-sensitive communication requirements, and feeds this information back to CUC and CNC. Based on this feedback, configuration parameters are automatically adjusted in real-time to optimize network performance while maintaining latency thresholds, thereby improving productivity through a manageable feedback-driven optimization process
Solution Approach 2:
The CUC and CNC entities serve multiple functions: they receive analytics data, process configuration decisions, generate configuration parameters, and distribute them to various network elements. This multi-functionality consolidates what would otherwise require separate systems into unified configuration managers, reducing overall system complexity while enabling comprehensive real-time monitoring and optimization
3Adaptability or versatility
If centralized configuration functions are added, then time-sensitive communication management capability is improved, but device complexity increases
Solution Approach 1:
The system manages adaptability by dynamically changing configuration parameters rather than requiring complex architectural modifications. CUC and CNC adjust parameters such as priority levels, latency thresholds, and routing preferences based on real-time analytics, enabling the network to adapt to varying time-sensitive communication requirements through parameter optimization rather than structural complexity

AI summary
A system may determine that a particular communication session, between a User Equipment (“UE”) and a wireless network, is associated with a set of time-sensitive communication policies; output a first indication, to one or more Network Functions (“NFs”) of the wireless network with which the particular communication session is associated, that the particular communication session is associated with the set of time-sensitive communication policies; output a second indication, to one or more routing devices via which the one or more NFs communicate, that the particular communication session is associated with the set of time-sensitive communication policies; receive, from the one or more NFs, a first set of Key Performance Indicators (“KPIs”) associated with the time-sensitive communication session; receive, from the routing devices, a second set of KPIs associated with the time-sensitive communication session; and output the first and second sets of KPIs to an analytics element of the wireless network.
