Dynamic Quota Management for Low-Latency User Services
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
The 3GPP standard specifications face challenges in balancing network element performance, access latency, and credit control risks, particularly in latency-sensitive services like uRLLC, due to the use of non-blocking quota requests that can lead to resource waste and DoS attacks.
Innovation Solution
A policy control device dynamically determines and adjusts quota management modes between blocking and non-blocking, suspend and resume, to ensure real-time balance between latency and credit control risks.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Loss of time
If quota request in non-blocking mode is used, then access latency is reduced, but credit control risks increase and resource waste occurs
Solution Approach 1:
The patent implements dynamic quota management mode selection, where the SMF device can switch between blocking and non-blocking modes based on real-time service requirements and network conditions. This dynamic adjustment allows the system to optimize for low latency when appropriate while maintaining credit control security when needed, resolving the contradiction between speed and reliability.
Solution Approach 2:
The patent changes the operational parameter of quota request mode from a fixed state to a variable state that can be adjusted between blocking and non-blocking modes. This parameter change enables the system to adapt to different service scenarios, achieving low latency for latency-sensitive services while maintaining security for other services.
2Reliability
If quota request in blocking mode is used, then credit control risks are reduced, but access latency increases
Solution Approach 1:
The system dynamically selects between blocking and non-blocking quota request modes based on service characteristics and network conditions. For latency-sensitive services, the system chooses non-blocking mode to minimize access latency, while for other services, blocking mode ensures credit control security, thus resolving the contradiction between reliability and speed.
Solution Approach 2:
The patent changes the quota request mode parameter from a fixed blocking mode to a flexible parameter that can be set to either blocking or non-blocking based on real-time requirements. This enables the system to reduce access latency when needed while maintaining credit control reliability when appropriate.
3Loss of time
If suspend quota management mode is used, then access latency is reduced, but resource waste and carrier losses increase
Solution Approach 1:
The patent implements dynamic switching between different quota management modes including suspend, resume, blocking, and non-blocking modes. The system selects the appropriate mode based on service characteristics, user behavior, and network conditions, avoiding the resource waste of suspend mode while maintaining its latency benefits when appropriate.
Solution Approach 2:
The patent changes the quota management mode parameter from a fixed suspend mode to a flexible parameter that can be adjusted between multiple modes. This enables the system to achieve low access latency when needed while avoiding resource waste by selecting more appropriate modes for different scenarios.

AI summary
A service processing method and a related product is applied to the charging field. A policy control device generates a first policy of a user service, and sends the first policy to a session management function device to indicate the session management function device to perform a first quota management mode on the user service. The policy control device receives related information of a second quota management mode of a user or the user service, and determines the second quota management mode. The policy control device generates a second policy of the user service based on the second quota management mode, where the second policy is for updating or replacing the first policy. According to this method, the quota management mode of the user service is time-effective, ensuring a balance between a latency condition and credit control risks.
