VoWiFi Registration Control Using Position Verification in Roaming
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
VoWiFi registration in a roaming environment often leads to charging disputes due to network layout loopholes, causing billing discrepancies.
Innovation Solution
Implement a method and apparatus for VoWiFi registration control that utilizes position feature information to match and verify information during the registration process, allowing for termination of VoWiFi registration if the information does not match, thereby preventing charging disputes.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Adaptability or versatility
If VoWiFi registration is allowed in roaming environment, then service availability is improved, but charging accuracy deteriorates due to network layout loopholes
Solution Approach 1:
The patent performs preliminary position verification by comparing the device's current position with the position associated with the subscriber's home network before allowing VoWiFi registration. This preliminary check prevents charging disputes by ensuring the device is in a legitimate roaming scenario, thus maintaining service availability while protecting charging accuracy.
Solution Approach 2:
The patent introduces position information as an intermediary element between the device and the charging system. By verifying position feature information against the home network's records, the system mediates between allowing roaming service and preventing charging disputes, resolving the contradiction between service availability and charging accuracy.
2Measurement precision
If position verification is performed during VoWiFi registration, then charging accuracy is improved, but registration process complexity increases
Solution Approach 1:
The patent extracts position verification as a separate, independent step from the main VoWiFi registration process. The position feature information is obtained and verified independently before proceeding with registration, which simplifies the overall process structure while maintaining charging accuracy. This modular approach reduces complexity by clearly separating the verification function.
3Reliability
If VoWiFi registration is controlled based on position information, then charging disputes are reduced, but registration time increases
Solution Approach 1:
The position verification is performed as a preliminary action using pre-existing position feature information that is already associated with the subscriber's home network. Since this information is obtained in advance and stored, the verification process is quick and does not significantly increase registration time, while effectively preventing charging disputes.

AI summary
A VoWiFi registration control method and apparatus, an electronic device, and a server, are provided. A method on an electronic device side includes: obtaining first feature information of an electronic device; and controlling, in a case that the first feature information does not match second feature information, termination of VoWiFi registration in a process of performing VoWiFi registration. The first feature information is position feature information determined based on a first position of the electronic device, and the second feature information is position feature information determined based on a second position of the electronic device.
