5G Charging Trigger Coordination for Quota Mode Switching
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The existing 3GPP standard specifications for charging systems in 5G networks face challenges in balancing performance burden, access delay, credit control risk, and network security, particularly in handling delay-sensitive and uninterruptible services, leading to increased operator losses and user experience issues.
Innovation Solution
A user service processing method that dynamically adjusts charging operations based on scenario-specific conditions, allowing for both blocking and non-blocking mode initial quota requests, with the charging processing device providing real-time feedback to the charging trigger device to manage quota requests and service termination or suspension.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If blocking mode initial quota request is applied, then credit control risk is reduced, but access delay is increased
Solution Approach 1:
The patent applies dynamics by enabling the charging system to dynamically switch between blocking and non-blocking modes based on real-time service characteristics and account status. The charging trigger device determines the appropriate mode by evaluating service types (delay-sensitive vs. non-delay-sensitive) and account balance conditions, allowing the system to adapt its quota request behavior rather than using a fixed mode.
Solution Approach 2:
The patent changes the parameter of initial quota request mode from a static configuration to a dynamic parameter that can take different values (blocking or non-blocking) based on service characteristics. By modifying this parameter according to service type and account status, the system optimizes both credit control and access delay performance for different scenarios.
2Loss of time
If non-blocking mode initial quota request is applied, then access delay is reduced, but credit control risk is increased
Solution Approach 1:
The system dynamically selects non-blocking mode for delay-sensitive services while maintaining blocking mode for other services. This dynamic selection allows the system to reduce access delay where critical while maintaining credit control where necessary, based on real-time service characterization.
Solution Approach 2:
The patent applies local quality by treating different service types differently within the same charging system. Delay-sensitive services receive non-blocking treatment locally, while other services maintain blocking mode, allowing optimized performance for specific service categories without compromising overall system security.
3Productivity
If blocking mode is always applied, then system performance burden is reduced, but user experience is degraded
Solution Approach 1:
The system dynamically adjusts its operational mode based on service requirements, switching between blocking and non-blocking approaches. This dynamic behavior reduces unnecessary performance burden while improving user experience for delay-sensitive services, avoiding the always-blocking approach's degradation of user experience.
4Ease of operation
If non-blocking mode is always applied, then user experience is improved, but network security risk is increased
Solution Approach 1:
The patent applies local quality by providing non-blocking mode treatment only to delay-sensitive services that require it, while maintaining blocking mode for other services. This selective approach improves user experience where necessary without exposing the entire network to security risks associated with universal non-blocking operation.
Solution Approach 2:
The system changes the operational mode parameter based on service characteristics and account status, using non-blocking mode selectively rather than universally. This parameter adjustment reduces network security risk by maintaining blocking mode for services where it provides security benefits.

AI summary
A user service processing method in a charging system is as follows: A charging trigger device (102) provides initial quota application mode indication information for a charging processing device (101), so as to indicate an initial quota request mode previously applied by the charging trigger device (102) for a user service. The charging processing device (101) performs charging processing on the user service based on the indication information, and delivers a charging processing result to the charging trigger device (102), to enable the charging trigger device (102) to change a charging operation on the user service. In this way, by changing a cooperation relationship between the charging processing device (101) and the charging trigger device (102), a balance between performance of the charging system and a credit control risk, or between an access delay and a credit control risk is implemented.
