PLMN Identifier Handling in Network Sharing Charging Systems
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless network communication, when a radio access network is shared, the charging system may incorrectly charge users based on the PLMN identifier of the current serving network rather than the network name displayed by the user equipment, leading to inaccurate billing.
Innovation Solution
A method and system where a mobility management device acquires and transmits the PLMN identifier corresponding to the network name displayed by the user equipment to a call detail record information generating device, ensuring that user call detail record information includes this identifier, which is then used by the charging device to charge the user accurately based on the displayed network name.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If the charging device uses the PLMN identifier of the current serving network to charge the user, then the charging process is simple and fast, but the charging accuracy becomes incorrect when network sharing occurs
Solution Approach 1:
The mobility management device acts as an intermediary between the user equipment and the charging device. It acquires the PLMN identifier from the user equipment's displayed network name and transmits this information to the charging device, enabling accurate charging while maintaining system simplicity
Solution Approach 2:
The system establishes a feedback mechanism where the mobility management device continuously monitors the user equipment's displayed network name and transmits the corresponding PLMN identifier to the charging device, ensuring the charging system has up-to-date information about the user's network affiliation
2Device complexity
If the call detail record information generating device uses only the current serving network's PLMN identifier, then the system complexity is low, but the charging information processing becomes inaccurate under network sharing conditions
Solution Approach 1:
The mobility management device performs preliminary action by acquiring the PLMN identifier from the user equipment before the charging process occurs. This pre-acquired information is then transmitted to the charging device, ensuring accurate charging information is available without increasing system complexity
Solution Approach 2:
The mobility management device performs multiple functions: it manages mobility for the user equipment, acquires network identification information, and transmits this information to the charging device. This multi-functionality eliminates the need for separate complex systems while ensuring charging accuracy

AI summary
Embodiments of the present invention provide a method, an apparatus and a system for processing charging information, wherein the method includes: a mobility management device acquires a PLMN identifier corresponding to a network name displayed by a user equipment; transmits the PLMN identifier corresponding to the network name displayed by the user equipment to a call detail record information generating device, so that user call detail record information generated by the call detail record information generating device includes the PLMN identifier corresponding to the network name displayed by the user equipment; therefore, a charging device can charge the user according to the network name displayed by the UE included in the user call detail record information generated by the call detail record information generating device, thereby ensuring accuracy of the charging the user, and enhancing user experience.
