Synchronizing QoS and PCC Rule Activation Timing

Resolve Bottlenecks,
Find Innovative SolutionsGenerate Solutions

Solution Overview

Problem

In existing Policy and Charging Control (PCC) systems, the activation and deactivation times of Quality of Service (QoS) rules are not consistently indicated, leading to resource wastage and misactivation, as the BBERF entity activates QoS rules immediately without time indications, causing inconsistencies with PCC rule activations in the network.

Innovation Solution

The PCRF entity determines and provides time indications for the activation and deactivation of QoS rules to the BBERF entity, ensuring that these rules are activated and deactivated in sync with corresponding PCC rules, thereby maintaining consistency and optimizing resource management.

Solution Approach 1:

The PCRF entity performs preliminary action by determining and providing time indications for QoS rule activation and deactivation before the BBERF entity activates the rules. This ensures that the BBERF entity can synchronize its rule activation with PCC rule activations, preventing misactivation and resource wastage while maintaining quick response times

Inventive Principle:

Principle #10Preliminary action

Solution Approach 2:

The system implements feedback by having the PCRF entity provide time indication information to the BBERF entity based on PCC rule time indications. This feedback mechanism ensures that the BBERF entity activates and deactivates QoS rules at the correct times, maintaining consistency with PCC rule activations and improving overall system reliability

Inventive Principle:

Principle #23Feedback

AI summary

The disclosure discloses a method for Policy and Charging Control (PCC) based on a time period, which comprises: when a Policy and Charging Rule Function (PCRF) entity provides Quality of Service (QoS) rules to a Bearer Binding and Event Reporting Function (BBERF) entity, a time indication of activation and/or deactivation of the QoS rules is provided at the same time. The disclosure also discloses a system for PCC based on a time period, which comprises: a providing unit located in the PCRF entity and configured to provide QoS rules and a time indication of activation and/or deactivation of the QoS rules to the BBERF entity at the same time. The disclosure ensures the consistency between the time of activating the QoS rules by the BBERF entity and the time of activating the PCC rules by the Policy and Control Enforcement Function (PCEF) entity, and the technical scheme is simple and practical.
