Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current communication systems face challenges in efficiently selecting the appropriate network functions for user equipment groups, particularly in scenarios involving unmanned aerial systems, where optimal network function selection is crucial for communication session management and traffic filtering.
Innovation Solution
The apparatus and method involve receiving an indication of a user equipment group's identifier and using it to select a second network function, such as a session management or user plane function, based on the group's profile or context data, which can include communication session type and location, to ensure efficient communication and traffic management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If traditional network function selection methods are used for user equipment groups, then individual device handling is simple, but communication efficiency and latency optimization for group-based scenarios deteriorate
Solution Approach 1:
The patent segments network function selection by introducing group identifiers that categorize user equipment into distinct groups. This allows the network to apply different selection strategies for different groups, optimizing communication efficiency for time-sensitive applications while maintaining manageable complexity through structured group-based segmentation.
Solution Approach 2:
The patent implements preliminary action by pre-configuring group identifiers and associated network function profiles before communication sessions are established. This allows the network to have selection criteria ready in advance, reducing latency for time-sensitive communications without requiring complex real-time decision-making during session establishment.
2Loss of time
If group-based network function selection is implemented, then communication efficiency for time-sensitive applications improves, but the complexity of network function management increases
Solution Approach 1:
The patent reduces communication latency by performing preliminary configuration of group identifiers and network function associations before actual communication sessions. This pre-preparation ensures that time-sensitive applications can immediately use pre-determined optimal network functions without requiring complex real-time analysis, thus minimizing time loss while managing complexity through advance planning.
Solution Approach 2:
The patent manages complexity by changing the parameter of network function selection from individual device-based to group-based identification. This parameter change simplifies the management approach by using group-level characteristics rather than individual device parameters, reducing the computational complexity of real-time decisions while maintaining optimization for time-sensitive communications.
3Ease of operation
If individual user equipment handling is used, then network function selection is straightforward, but optimization for group-based time-sensitive communications deteriorates
Solution Approach 1:
The patent maintains ease of operation by segmenting user equipment into groups with common characteristics, allowing network function selection to be based on group identifiers rather than complex individual device analysis. This segmentation approach preserves operational simplicity while enabling optimization for time-sensitive communications by applying group-specific selection criteria that account for collective performance requirements.
Solution Approach 2:
The patent applies universality by creating group identifiers that can represent multiple user equipment devices with similar communication requirements. This multi-functionality approach allows a single group-based selection mechanism to serve various time-sensitive application scenarios, maintaining ease of operation through a unified selection process while improving performance across different group types.
