Wireless Measurement Configuration Identifier Transfer
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communication networks, the existing solutions for transferring Quality of Experience (QoE) measurement configuration files are inefficient, as large files are sent repeatedly, consuming resources and wasting bandwidth, especially when UE transitions between idle and connected modes, and not all UEs use streaming services frequently.
Innovation Solution
Implementing a system where the RAN sends a unique configuration identifier to the UE, which retrieves the measurement configuration file only when necessary, such as when transitioning to connected mode or starting a streaming service, reducing unnecessary resource consumption by avoiding repeated transmissions of the entire configuration file.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the RAN sends the measurement configuration file to the UE every time the UE enters connected mode, then the UE has the latest configuration information, but unnecessary resources are consumed and bandwidth is wasted
Solution Approach 1:
The patent extracts only the essential configuration identifier from the full measurement configuration file and transmits it to the UE. The UE uses this identifier to retrieve the complete configuration file from its local storage, avoiding unnecessary transmission of the entire large configuration file while ensuring the UE has access to updated configuration information.
Solution Approach 2:
The patent implements preliminary action by having the UE store the measurement configuration file locally before entering idle mode. When the UE transitions back to connected mode, it can quickly retrieve the configuration using the pre-stored file and identifier, eliminating the need to retransmit the full configuration file and reducing resource consumption.
2Adaptability or versatility
If the measurement configuration file is sent to all UEs, then UEs that use streaming services can perform measurements, but resources are wasted on UEs that do not use streaming services
Solution Approach 1:
The patent implements self-service by enabling the UE to autonomously determine whether to retrieve and execute the measurement configuration file based on its own service usage patterns. The UE checks its local storage for the configuration identifier and retrieves the configuration file only when needed, without requiring the network to push configurations to all UEs, thereby reducing unnecessary data transmission.
3Loss of energy
If the configuration identifier is transmitted instead of the full configuration file, then resource consumption is reduced, but the UE must have the configuration file stored locally
Solution Approach 1:
The patent applies segmentation by dividing the measurement configuration system into two parts: a small configuration identifier that is transmitted to the UE, and the full measurement configuration file that is stored locally in the UE. This segmentation allows the network to transmit minimal information while the UE maintains the complete configuration locally, reducing transmission overhead without significantly increasing UE complexity.
Data Source
AI summary
Methods and related user equipment and radio network node are described in which the UE receives a measurement configuration message via the radio network node, the measurement configuration message comprising a configuration identifier associated with a measurement configuration file, and in which the UE retrieves the measurement configuration file from the radio network node using the received configuration identifier.
