Buckets Data Model(3.0)
The UDRs in PCC.Buckets store usage related data for each subscriber. Use the APL function pccBucketDataLookup
(see the section pccBucketDataLookup in APL - PCC BucketData Support - Buckets(3.0)) to get a BucketDataHolder from the database and the APL function pccBucketDataStore
(see the section pccBucketDataStore in APL - PCC BucketData Support - Buckets(3.0)) to store a BucketDataHolder in the database.
See APL - PCC BucketData Support - Buckets(3.0) for further information about how to use the PCC.Buckets UDRs with APL and REST HTTP Interface - Buckets(3.0) for information on how to access the PCC.Buckets UDRs from the REST HTTP interface.
From the BucketDataHolder all usage related data for a subscriber is accessible via the following objects in the data model:
Object | Description |
---|---|
Buckets | Stores the actual usage information and statistics. There can be multiple buckets and multiple types of information counted. When a recurring usage counter is reset, its previous values can be kept for future processing. |
Sessions | Stores session related data. No additional data to uphold a session should be needed, that is, do not rely on workflow memory to hold any session information. |
Subscriber | Stores meta data about the subscriber necessary for usage counting. The amount of data should be kept to a minimum and only hold data to reduce the number of times an external subscriber database needs to be queried. |
Overview of the BucketDataHolder Data Model
The different UDRs within the BucketDataHolder Data Model are connected as follows:

The first subscriber will receive notifications 700, 702 and 703, while the second subscriber will only receive notification 703.
Both subscribers will also receive any notifications that has been set to be Required, see Notification UDR in Product Data Model(3.0).
Bucket UDR
The Bucket UDR stores the actual usage information and statistics. Each bucket references one product and has a start time and stop time that determines when the bucket should be activated and expire. Each bucket also contains one or several counters which are depending on the configuration for the selected product.
Field | Description |
---|---|
| The ID of the bucket. The ID must be unique within the bucket list, and is used to identify a particular bucket both in the BucketDataHolder UDR, and from the REST HTTP interface. |
| References a product using its identifier. Each bucket must be associated with a product. The product has information that controls the behavior of the bucket. |
| The date and time when the bucket is to be activated, or when the last reset was done, depending on if the date is in the future or in the past. |
| The date and time when the bucket expires. |
| Holds a list of counters. Each counter in the list can count multiple items. The list can retain multiple counters depending on the product configuration. |

will give the following setup:
The IDs for the three buckets; 1, 2 and 3, are used in the BucketDataHolder UDR for determining which buckets usage should be counted in.
All of the buckets will start on the 1st of October and expire by the end of the 30th October, but at different times of the day.
The counters for the first bucket has counted 100 bytes in output, 200 bytes in input and 300 bytes in total.
The counters for the second bucket has counted 50 bytes in output, 300 bytes in input and 350 bytes in total.

Below is a screenshot of the UDR Assistance displaying the Counter UDR:
Counter UDR
Example - Counter UDR
The following values when counting usage in bytes:
Usage={0: 100, 1: 200, 2: 300} Usage={0: 50, 1: 300, 2:350} Usage={0: 20, 1: 100, 2:120}

The second counter has counted 50 byte in input, 300 bytes in output and 350 bytes in total
The third counter has counted 20 bytes in input, 100 bytes in output and 120 bytes in total.
Note!
This is an example configuration. Usage can be used for measuring other types of usage, and other keys than 0, 1 and 2 may be used.
Session UDR
The Session UDR stores data related to Diameter sessions, which includes information about the rules that applies, the workflow that is responsible for the session, any reservations made, when the session was last active, the session destination and the protocol used for the session.
