Acronyms

This section lists terms specific to this document. Table 2 Acronyms lists the acronyms used in the document.

Term	Definition
Auto-Enrollment	The ability for the SPR to create a Subscriber profile for an unrecognized subscriber identity, based on a pre-determined message received on one of the provisioning or traffic interfaces. The identity contained in the received message is used to create a default profile in the database.
Basic Pool	Refers to the existing quota pooling capabilities prior to this feature. Basic pools support up to 25 members.
Diameter Sh TPS	The number of Diameter transactions per second that are supported on the Sh signaling interface. A transaction is comprised of one Diameter Sh message received plus one message sent plus all of the processing required within the UDR system to handle the request
Enterprise Pool	A new type of pool introduced by this feature. This pool supports the sharing of pool quota across 1500 members.
Exhaustion	Exhaustion occurs when reports indicate that use of a metered unit has equaled or exceeded the specified quota limit. If a recurring Quota is exhausted, typically the sessions for the subscriber are subjected to more restrictive policies until the end of the Plan period or Billing Cycle.
Expiration	Expiration occurs when a periodic Quota reaches the end of the Plan period or Billing Cycle, or when a one-time quota reaches its established End Time or the close of its Validity period Note: The time-based expiration of a Quota is different from the exhaustion of a Quota restricting the active session Time of the usage for the subscriber. A periodic Quota is typically Reset at expiration.
Non-Pool Host UDR	The UDR which hosts pool members for which pool data resides on Pool Host UDR.
Opaque Data	A data type that is incompletely defined in an interface, so that its values can only be manipulated by calling subroutines that have access to the missing information. The concrete representation of the type is hidden from its users.
Partial Pool Member	A pool member in a pool on the Non-Pool Host UDR in which the pool does not yet have the Pool Profile from the Pool Host UDR. This may be because the pool has not been created yet on the Pool Host UDR or because it was never received from the Pool Host UDR. Whenever a partial pool member is added the Pool Entity data is requested from the Pool Host UDR.
Pass	A Pass is a one-time override which temporarily replaces or augments the default plan or service for the subscriber or service. While a Pass is in effect, it may modify the QoS controls, charging parameters, or other configurable rules associated with the service for a subscriber. A Pass may: Be valid for a restricted interval Start when provisioned, or at a specific time, or upon the occurrence of a triggering event within its validity interval End at a specific time, or after given duration once activated, or upon a particular event Apply continuously, or only during certain time periods, or only under certain conditions (for example, when roaming) Apply to the overall usage for the subscriber, or be more limited (for example, applying only to specific applications, flows, traffic types, or pre-defined rules) Passes are common options for pre-paid subscribers, who frequently have limited or no data access via their basic Plan, and may purchase Passes to gain access to such services. They can also be used to allow Casual Use plans for pre- or post-paid subscribers to purchase services on an occasional basis which they would not otherwise subscribe for on an ongoing basis.
Plan	The plan for a subscriber is the description of their basic, recurring service. Frequently, the Tier and/or Entitlement fields of profile data for the subscriber may be used to indicate or derive the plan type. Plans include enforceable policy characteristics (QoS and Charging parameters and PCC rules) computed automatically or through policy rules. A Plan may have associated Quota controls (see Basic Quota), which in turn may be subject to modification or over-ride through Passes, Top-ups, and Roll-overs (see below).
Pool Host UDR	The UDR which hosts pool data which may have pool members on other UDR systems.
Pool Network	Refers to the network of UDR servers across which a quota pool can span.
Provisioning TPS	Provisioning transactions per second, which is comprised of one provisioning message received plus one message sent plus all of the processing required within the UDR system to handle the transaction.
Quota	A Quota specifies restrictions on the amount of data Volume, active session Time, or service-specific Events that a subscriber can consume. A single Quota may express limits on any combination of Volume, Time, or Events. Quotas may be associated with a time period during which activity is measured.
Roll-over	Roll-over is a mechanism by which usage which was not consumed during one Quota period may be applied as a credit in a future period. Roll-over may apply to Basic Quotas associated with plan for a subscriber or may affect Passes or (more usually) Top-ups purchased by the subscriber. Roll-overs may be limited as to the amount that can be credited to the future period, or by capping the total amount of (basic and rolled-over) credit that may be available in a given period. They may also have limitations regarding the number of cycles that credits may be rolled into. In other words, Roll-over rules modify the process of resetting a recurring Quota.
Subscription Data Object	An SDO comprises of subscription state information combined with a collection of registers for storing entities. An SDO is accessed using an SDO ID and is stored in the UDR DB. SDOs come in two types: individual or pool. An individual SDO applies to one subscriber. A pool SDO applies to a group of subscribers.
Transparent Data	A data type whose representation is visible to the users.
Threshold	A Threshold is a soft limit at which usage must be reported during the monitoring of a Quota, usually lower than the full limit associated with the Quota. Typically, service parameters are not adjusted when a Threshold is reached, but other actions may be taken, such as notifying the user of their current usage.

Typically, service parameters are not adjusted when a Threshold is reached, but other actions may be taken, such as notifying the user of their current usage.
Top-up	A Top-up is a modifier which takes effect only upon exhaustion of Basic Quota associated with plan or default service for a subscriber. Top-ups allow the subscriber to extend their access to services beyond the time or volume limits typically enforced.
Ud Client	An Ud Client is an FE that uses the Ud Interface to access subscriber data from a User Data Repository
Ud Interface	The Ud Interface is an access protocol as defined in 3GPP TS 29.335. It defines a logical connection between a Front-End (FE) and a User Data Repository. The Ud Interface consists connections using LDAP to perform CRUD operations on subscriber data (Create/Delete/Update/Read), and connections using SOAP for publishing/subscribe interface in order to request notifications when subscriber data stored in the User Data Repository changes, and to receive those notifications when the data is changed.
Ud Server	An Ud Server is a User Data Repository that has an Ud Interface to allow external Front-Ends to access subscriber data via LDAP and SOAP, according to the Ud Interface specification.
