Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If charging systems use unified rates for all radio access technologies, then charging simplicity is maintained, but charging accuracy and fairness deteriorate because different access technologies provide different service capacities and effects
Solution Approach 1:
The patent segments the charging system by introducing radio access technology type as a charging dimension. The CDF is configured with multiple rates corresponding to different radio access technology types (e.g., E-UTRAN, UTRAN). When generating charging records, the system identifies the radio access technology type used by the terminal and applies the corresponding rate, thereby achieving differentiated charging without requiring complex system architecture changes.
Solution Approach 2:
The patent changes the charging parameter structure by adding radio access technology type information to the charging record. The CDF stores multiple rates with different radio access technology type parameters, and dynamically selects the appropriate rate based on the terminal's actual access technology. This parameter-based differentiation enables accurate charging while maintaining system simplicity.
2Adaptability or versatility
If charging records include detailed radio access technology information, then charging differentiation capability is improved, but information processing complexity increases
Solution Approach 1:
The patent extracts the radio access technology type information from the complex session signaling and transmits it separately in the charging request message from BM-SC to CDF. This extraction approach isolates the critical charging parameter from other session information, reducing the processing complexity while maintaining the ability to differentiate charging by access technology type.
Solution Approach 2:
The CDF is pre-configured with multiple rates corresponding to different radio access technology types before actual charging operations. This preliminary configuration allows the system to quickly match the terminal's access technology with the appropriate rate without real-time complex calculations, thereby enhancing charging differentiation capability while minimizing information processing complexity during operation.
3Reliability
If the system tracks radio access technology type for charging, then service quality differentiation is improved, but signaling overhead increases
Solution Approach 1:
The patent uses the BM-SC as an intermediary to obtain and forward radio access technology type information to the CDF. The BM-SC collects this information from session signaling and includes it in the charging request message, eliminating the need for direct complex interactions between other network elements and the CDF. This intermediary approach enables service quality differentiation while minimizing overall signaling overhead.

AI summary
The present invention discloses a method and system for obtaining access information in a Multimedia Broadcast/Multicast Service (MBMS). The method includes the following steps: during an eMBMS session, a broadcast/multicast service center (BM-SC) configures access information in one or more MBMS session signaling, and sends the MBMS session signaling to an MBMS gateway within a service area of the BM-SC; wherein the access information at least includes radio access technology type information. The present invention also discloses a method and system for charging in an MBMS. The methods and systems of the present invention can take the access information including the radio access technology type as the basis of charging, supply communication operators with a charging manner of distinguishing radio access technology types, and adopt different rates corresponding to the MBMS service areas of different radio access technology types, and thus charging can be further detailed.
