5G Traffic Influence Mapping for Unambiguous Route Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing 5G network traffic influence methods fail to accurately interpret multiple traffic flow requests, leading to inefficient API invocations and subscriptions across network functions due to the lack of clear mapping between traffic filters and routes.
Innovation Solution
Introduce new attributes in traffic influence requests, including a map with set identification numbers (SID) and associated traffic filters or ethernet traffic filters, along with traffic routes, to ensure unambiguous interpretation and efficient routing.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If multiple traffic influence requests are sent without clear mapping between traffic filters and routes, then the network can process diverse service requirements, but the interpretation accuracy of traffic flow requests deteriorates leading to inefficient API invocations
Solution Approach 1:
The patent segments the traffic influence requests into distinct sets, each containing a specific traffic filter and its corresponding traffic route. This segmentation is achieved by introducing a new attribute structure that divides the request into multiple sets, where each set independently maps a traffic filter to a traffic route. This allows the network to process diverse service requirements while maintaining clear and accurate interpretation of each traffic flow request, thereby resolving the contradiction between versatility and interpretation accuracy.
2Adaptability or versatility
If multiple traffic influence requests are processed without clear mapping, then service diversity is supported, but the number of API invocations and subscriptions increases leading to resource inefficiency
Solution Approach 1:
The patent merges multiple traffic influence requests into a single structured attribute called 'sets', where each set contains a traffic filter and its corresponding traffic route. This merging approach allows the network to process multiple traffic flow requests simultaneously in a unified manner, reducing the number of separate API invocations and subscriptions required. By combining multiple requests into a single structured format, the system maintains service diversity while improving resource management efficiency and reducing unnecessary API calls.
3Adaptability or versatility
If traffic filters and routes are not clearly mapped, then the system remains flexible, but the routing accuracy and unambiguous interpretation of requests deteriorates
Solution Approach 1:
The patent introduces an intermediary structure called 'sets' that acts as a mediator between traffic filters and traffic routes. Each set in the attribute contains a traffic filter and its corresponding traffic route, creating a clear and unambiguous mapping relationship. This intermediary structure ensures that the system maintains flexibility to handle diverse traffic types while achieving accurate and reliable routing. The set structure serves as a bridge that connects traffic filters to their respective routes without ambiguity, thereby resolving the contradiction between flexibility and routing accuracy.

AI summary
The present disclosure provides new attributes in a request that includes mapping of the at least one traffic filter or at least one ethernet traffic filter with at least one traffic route in a map. In AF's create request the map includes a plurality of sets where each set includes a set identification number (SID), one of: the at least one traffic filter or the at least one ethernet traffic filter, and the at least one traffic route as the attributes. Further, each SID identifies each entry of at least one set in the map. In AF's update request, the map includes at least one set where each set includes a set identification number (SID) and optional attributes. The optional attributes comprise one or more of: at least one traffic filter and one of: at least one ethernet traffic filter or at least one traffic route. Further, each SID identifies each entry of at least one set in the map. This provides clarity for NEF to unambiguously interpret the external AF's create or update requests and translate the information towards the other 5G Core entities.
