Radio Device Proxy Server Activation for Policy Rule Enforcement
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Mobile network operators face challenges in determining whether a radio device is application or domain aware, leading to policies and rules not being enforced, resulting in decreased network performance.
Innovation Solution
A policy node activates a proxy server in the radio device to enable it to apply policies, even if it is not application or domain aware, by sending a message with activation and configuration instructions.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If a radio device connects to multiple cell groups simultaneously, then communication reliability is improved through diversity, but processing complexity and power consumption increase
Solution Approach 1:
The patent extracts and isolates the policy decision-making function into a separate network-side entity (policy node). The radio device no longer needs to maintain complex policies for multiple cell groups locally, but only needs to report measurements and receive policy decisions, significantly reducing device complexity while maintaining the ability to connect to multiple cell groups for reliability
Solution Approach 2:
The policy node acts as an intermediary between the network and the radio device. It receives measurement information from the device, determines appropriate cell group configurations and reporting policies, and returns decisions to the device. This intermediary handles the complex processing centrally, freeing the device from complexity while enabling reliable multi-cell group operation
2Speed
If the radio device autonomously determines cell group configurations, then response speed is improved, but configuration accuracy and reliability deteriorate due to lack of network coordination
Solution Approach 1:
The network pre-configures measurement configurations and reporting policies through the policy node before the radio device needs to make decisions. The policy node determines appropriate cell group configurations based on network state and device capabilities in advance, so when the device needs to act, it already has pre-determined policies to follow, achieving both speed and accuracy
Solution Approach 2:
The system implements a feedback loop where the radio device reports measurement information to the policy node, which then determines and returns appropriate cell group configurations and reporting policies. This closed-loop feedback ensures configurations are accurate and reliable while maintaining responsive operation through automated reporting triggers
3Measurement precision
If measurement reporting is triggered by multiple events simultaneously, then measurement precision is improved, but signaling overhead and power consumption increase
Solution Approach 1:
The patent applies different reporting policies to different cell groups based on their specific characteristics and requirements. Each cell group can have its own measurement events and reporting triggers configured by the policy node, allowing precise measurement where needed while avoiding unnecessary reporting in other cell groups, thus reducing power consumption while maintaining measurement precision for critical cell groups
Solution Approach 2:
The system uses partial action by selectively triggering reporting only for specific cell groups and measurement types based on current network conditions and device state. The policy node determines which cell groups require reporting and what measurement events should trigger reports, avoiding excessive full-system reporting while maintaining precision for critical measurements

AI summary
A method performed by a policy node for handling policies related to a radio device in a communications network is provided. The radio device supporting proxy server functionality. During a session establishment of the radio device, the policy node determines (602) that obtained policies related to the radio device comprises one or more rules. The respective one or more rules comprises any one or more out of: An application descriptor related to the one or more rules, and a domain descriptor related to the one or more rules. The policy node determines (605), based on received capability information, that the radio device is not aware of any or more one out of an application and a domain, and that the radio device supports proxy server functionality. The policy node handles the policies related to the radio device by activating (606) a proxy server in the radio device by sending a message to the radio device. The message comprises: An indication requesting the radio device to activate the proxy server, the one or more rules, and a configuration related to the proxy server. The proxy server enables the radio device, even though not being application aware or domain aware, to apply the one or more rules comprised in the policies related to the radio device.
