TTC Is Returned In CCA When Not Expected (Doc ID 2878817.1)

Last updated on NOVEMBER 26, 2023

Applies to:

Goal

When a Top-up is purchased and the previous plan balance is still available, Credit-Control Answer (CCA) returned with Tariff Time Change (TTC) of Top-up purchase time,

which is not as expected as the rating does not change with respect to the time of Top-up purchase.

Scenario:

1. Configure the base plan:

Data of 102.4MB is granted every day for each zone through discount.

When a Top-up is purchased, data from the Top-up is consumed only after the daily data balance is fully consumed.

2. Create account with base plan.

Login: <Login ID>

3. Initiate Credit Control Request (CCR-U) Update

Requested-Service-Units (RSU) is 100MB;

Session ID: GPRS_1, Request number: 1

Data of 102.4MB is granted through discount for ZoneOS (Resource code: resource code).

100MB active reservation is done on data granted from base plan.

4. Purchase Top-up which grants 100MB data for ZoneOS in a different resource ID "resource_id".

5. Update a request with the Used-Service-Unit (USU) as 100MB

Session ID: GPRS_1, Request number: 2

Consumed 100MB from daily grant

Active reservation of remaining 2.4MB is done twice, which is not expected.

TCC is returned in CCA with Top-up purchase time, which is not expected.

Clarify the following two functional impacts:

1. The reservation and grants are out of sync, The reservation is more than grant which is not correct.

2. It is creating another bucket (sub-balance) with balance 0. How is it trying to reserve from that additional bucket?
