Dynamic Communication Quality Measurement via Network-Side Coordination
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Conventional communication quality measurement methods require pre-set and inflexible measurement conditions, leading to high processing loads in mobile devices and difficulties in performing various types of quality measurements, as they do not dynamically capture the time and location of measurements.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If measurement conditions are pre-set and fixed in conventional methods, then the measurement process is simple to implement, but the flexibility to perform various types of quality measurements is reduced
Solution Approach 1:
The measurement condition is transformed from a static pre-set configuration to a dynamic parameter that can be changed during operation. The network-side apparatus can dynamically adjust measurement conditions (timing, location, type) based on current network state and measurement needs, allowing flexible quality assessment without requiring complex pre-configuration on the mobile device.
Solution Approach 2:
A network-side apparatus is introduced as an intermediary between the measurement system and the mobile device. This intermediary handles the complex task of managing measurement conditions, coordinating measurement timing, and collecting data, thereby simplifying the mobile device's role while enabling versatile measurement capabilities.
2Measurement precision
If communication logs are constantly recorded in the mobile telephone to extract measurement data, then accurate measurement data can be acquired, but the processing load in the mobile telephone becomes higher
Solution Approach 1:
The data extraction function is extracted from the mobile device and transferred to the network-side apparatus. Instead of the mobile device constantly recording and processing logs locally, the network-side apparatus receives communication logs from the mobile device and performs the extraction and analysis centrally, reducing the mobile device's processing burden while maintaining measurement accuracy.
Solution Approach 2:
Instead of continuous constant recording, the system uses periodic measurement at predetermined timings coordinated by the network-side apparatus. The mobile device records data only during scheduled measurement periods rather than continuously, significantly reducing processing load while ensuring accurate measurement data is captured at appropriate moments.
3Ease of operation
If measurement conditions are informed in advance to the measurer, then the measurement process can be planned, but the measurement condition cannot be set or changed easily and optionally
Solution Approach 1:
Measurement conditions are made dynamically adjustable through the network-side apparatus. Operators can change measurement timing, location, and type conditions in real-time based on current network state or measurement needs, without requiring time-consuming reconfiguration of the mobile device. This dynamic adjustment capability provides ease of operation while maintaining measurement planning.

AI summary
Methods and systems of measuring communication quality are provided, by which various types of communication quality measurements can be flexibly performed as the measurement condition can be set or changed easily and optionally, while load of processing in the communication terminal apparatus can be suppressed. Measurement condition for measuring communication quality is delivered to a communication terminal apparatus capable of communicating via a mobile communication network and a communication with the communication terminal apparatus via the mobile communication network is performed at a predetermined timing that satisfies the measurement condition. Then, at least one of terminal-side measurement data including terminal-status log information and network-side measurement data including terminal-existing base-station quality information corresponding to communication corresponding to the predetermined timing which are recorded in the communication terminal apparatus is acquired, and an index value of communication quality in communication via the mobile communication network is calculated based on at least one of the terminal-side measurement data and the network-side measurement data.
