5G Service Rule Merging for Multiple Application Requests
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In the 5G network architecture, when multiple application requests are initiated by an application function (AF) for a user, the policy control function (PCF) establishes multiple service rules with varying priorities, leading to the lower priority rules not being executed, resulting in unresponsive application requests.
Innovation Solution
An overall service rule is formed that encompasses the service rules of multiple application requests, ensuring all rules are executed by the session management function (SMF) or updated to include new rules, prioritizing execution.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If multiple service rules are sent to the service decision with different priorities, then the high priority service rule can be executed first, but the lower priority service rule will not be executed resulting in unresponsive application requests
Solution Approach 1:
The patent combines multiple service rules into a single overall service rule that contains service rule identifiers for each individual service rule. This allows the service decision to execute all service rules through one unified rule rather than selecting only the highest priority rule, ensuring all application requests are responded to while reducing the complexity of managing multiple separate high-priority rules.
2Productivity
If the SMF selects only the service rule with higher priority for execution, then the execution efficiency is improved, but the service rule with lower priority is not executed resulting in lost application requests
Solution Approach 1:
The overall service rule is segmented into multiple individual service rules, each with its own identifier and priority level. The service decision can process these segmented rules in priority order while ensuring all are executed, maintaining execution efficiency through structured segmentation while preventing any application request from being lost.
3Adaptability or versatility
If multiple AF authorization sessions are established with the PCF respectively, then each application request can be authorized separately, but multiple service rules are sent to the same service decision causing the lower priority rule to be ignored
Solution Approach 1:
The overall service rule serves multiple functions by containing identifiers for multiple individual service rules within a single rule structure. This universal format allows the service decision to handle multiple application requests and their corresponding service rules through one unified mechanism, reducing the quantity of separate service rules transmitted while maintaining the ability to authorize each application request separately.
