Plan Depletion
A description of how the Plan Depletion action works is provided in this table.
| Feature | Description |
|---|---|
| Trigger | Triggered when the data usage of a specific data plan for an SIM card or IMSI reaches a preconfigured value of remaining balance (e.g. the user used 800MB of data from a prepaid 1GB data plan). |
| Focus | Data consumption. |
| Action | Triggers the PCRF module to start throttling. |
| Primary Use Case | Managing data usage within a specific allowance and transitioning users to a different plan after the allowance is exhausted. |
| Reset | PCRF rule ID is reset upon plan renewal or Top-up action to the specific plan. |
NOTE: The move to the next plan is not done by the Depletion Rule. The move to the next plan is done automatically by the Multi-Plan priority settings mechanism.
TIP: To implement a Plan Depletion action, refer to the Plan Depletion Rule.
A flowchart of the Plan Depletion process is shown here.
How Plan Depletion Works
The Plan Depletion action is implemented as follows:
- Initial State: A SIM is active with an assigned data plan and a Depletion Rule is set up within the CMP.
- Data Usage Monitoring: The CMP continuously monitors SIM data usage.
- Plan Depleted: When the SIM\IMSI primary data usage plan threshold is reached (as defined in the Depletion Rule) a throttling action is activated based on the PCRF/PCF ID.
- Throttling Action:
- The CMP triggers throttling action.
- The PCRF/PCF is notified and enforces the throttling speed associated with the configured PCRF/PCF Rule ID..
- The SIM\IMSI data speed is reduced.
- Continued Usage (Overage Multi-Plan): PCRF/PCF Rule ID is reset, and SIM goes back to normal speed.
