UE Policy Updates Triggered by Radio Frequency Band Changes
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing wireless networks struggle to dynamically adjust UE policies in response to changes in radio frequency connections, such as shifts between different radio access technologies or bands, leading to inconsistent Quality of Service (QoS) delivery.
Innovation Solution
The network automatically detects changes in radio frequency connections and updates UE policies accordingly, using triggers and conditions to ensure that the UE policies align with the current connection characteristics, thereby maintaining consistent QoS.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If UE policies are statically configured without dynamic updates, then network complexity is reduced, but QoS consistency deteriorates when RF connections change
Solution Approach 1:
The patent implements dynamic UE policy updates by establishing a monitoring mechanism that detects RF connection changes (such as band changes) and automatically triggers policy updates. The network moves from static policy configuration to dynamic adaptation, where policies are updated in real-time based on connection characteristics, thereby maintaining QoS consistency without excessive complexity
Solution Approach 2:
The patent employs a feedback mechanism where the network monitors RF connection parameters (such as band changes) and uses this information to trigger appropriate policy updates. The monitoring component continuously observes connection characteristics and provides feedback to the policy management system, enabling automatic adaptation while maintaining manageable network complexity through event-driven updates
2Reliability
If UE policies are dynamically updated based on RF connection changes, then QoS consistency is maintained, but network complexity increases
Solution Approach 1:
The patent segments the policy management system into distinct functional components: a monitoring component that tracks RF connection parameters, a decision component that determines when updates are needed, and an execution component that applies policy changes. This segmentation allows each component to perform its specific function efficiently, maintaining QoS consistency while managing network complexity through modular architecture
Solution Approach 2:
The patent pre-configures policy templates and update rules in advance, so that when RF connection changes are detected, the appropriate policies can be quickly applied without complex real-time decision-making. By preparing policy options beforehand and establishing update triggers in advance, the system maintains QoS consistency while reducing the computational complexity during actual policy updates

AI summary
A system described herein may receive, from a policy element of a core of a wireless network, a set of triggers associated with a plurality of radio frequency (“RF”) bands implemented by a radio access network (“RAN”). The system may identify that a User Equipment (“UE”) is connected to the RAN via a first RF band, and may identify a subsequent connection of the UE to the RAN via a second RF band. The system may identify that a particular trigger, of the set of triggers, is satisfied based on the subsequent connection of the UE to the RAN via the second RF band, and may indicate, to the policy element, that the particular trigger has been satisfied. The policy element may output a second set of UE policies for communications between the UE and the core of the wireless network based on the satisfaction of the particular trigger.
