UE Route Selection Policy for Dynamic PDU Session Traffic Handling
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional user equipment route selection policy rules in telecommunications networks are limited in flexibility and functionality, lacking the ability to dynamically modify or manage data traffic beyond simple routing decisions.
Innovation Solution
The user equipment is equipped with a user equipment route selection policy functionality that allows for data packet handling, modification, buffering, assignment to specific protocol data unit sessions, notification to the core network, and modification of the policy rules based on predefined indications, enabling more flexible and dynamic traffic management.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If conventional user equipment route selection policy rules are used for routing data packets, then the routing decision can be made, but the flexibility and functionality for dynamic traffic management is limited
Solution Approach 1:
The patent implements dynamic traffic management by enabling the user equipment to modify route selection policy rules in real-time based on network conditions and traffic characteristics. The system transitions from static routing decisions to dynamic adjustments, allowing the policy rules to adapt their parameters (such as routing preferences, bandwidth allocations) according to changing conditions, thereby resolving the contradiction between flexibility and complexity through controlled adaptability.
Solution Approach 2:
The invention applies parameter changes by allowing modification of existing route selection policy rules rather than creating entirely new rules. The system can adjust parameters such as traffic flow descriptors, session identifiers, and routing priorities within the existing policy framework, enabling enhanced functionality while maintaining the original structure and avoiding excessive complexity.
2Adaptability or versatility
If user equipment applies route selection policy information to steer traffic to PDU sessions, then routing control is achieved, but the ability to modify or manage data traffic beyond routing is limited
Solution Approach 1:
The patent implements multi-functionality by extending the route selection policy functionality to perform multiple operations beyond simple routing. The user equipment can now buffer data packets, modify packet content, apply quality of service policies, and manage traffic flows within the same policy framework that handles routing decisions. This universal approach allows a single system component to perform diverse traffic management functions, resolving the contradiction between versatility and complexity through functional integration.
3Productivity
If conventional route selection policy rules are used, then simple routing decisions can be made, but dynamic traffic management and real-time adjustments are not possible
Solution Approach 1:
The patent applies preliminary action by pre-configuring flexible policy rules that can be quickly activated and adjusted based on network conditions. Rather than making complex routing decisions in real-time for each data packet, the system establishes adaptable policy frameworks in advance that can be efficiently executed and modified as conditions change, thereby improving productivity while managing complexity through proactive configuration.

AI summary
A method for applying user equipment route selection policy information when operating a user equipment connected to a telecommunications network includes: in a first step, a considered data packet is received by a user equipment route selection policy functionality; and in a second step and based on the content of at least one modification and/or handling indication, one or more of the following actions is performed by the user equipment route selection policy functionality: the considered data packet is treated such as to be buffered, the considered data packet is modified and treated such as to be assigned to a specific protocol data unit session of the user equipment, a notification is transmitted, by the user equipment, to the core network of the telecommunications network, or the user equipment route selection policy information is modified.
