====
TBD
**RALs** is a standalone subsystem within **CGRateS** designed to handle two major tasks: :ref:`Rating` and :ref:`Accounting`. It is accessed via :ref:`CGRateS RPC APIs<remote-management>`.
.. _Rating:
Rating
------
Rating is the process responsible to attach costs to events.
The costs are calculated based on the input data defined within :ref:`TariffPlan` in the following sections:
.. _RatingProfile:
RatingProfile
^^^^^^^^^^^^^
Binds the event via a fixed number of fields to a predefined :ref:`RatingPlan`. Configured via the following parameters:
Tenant
The tenant on the platform (one can see the tenant as partition ID). Matched from event or inherited from :ref:`JSON configuration <configuration>`.
Category
Freeform field used to "categorize" the event. Matched from event or inherited from :ref:`JSON configuration <configuration>`.
Subject
Rating subject matched from the event. In most of the cases this equals with the *Account* using the service.
ActivationTime
Date and time when the profile becomes active. There is no match before this date.
RatingPlanID
Identifier of the :ref:`RatingPlan` assigned to the event.
FallbackSubjects
List of rating subjects which will be searched in order in case of missing rates in case of defined :ref:`RatingPlan`. This list is only considered at first level of iteration (not considering *FallbackSubjects* within interations).
.. Note:: One *RatingProfile* entry is composed out of a unique combination of *Tenant* + *Category* + *Subject*.
.. _RatingPlan:
RatingPlan
^^^^^^^^^^
Groups together rates per destination and relates them to event timing. Configured via the following parameters:
ID
The tag uniquely idenfying each RatingPlan. There can be multiple entries grouped by the same ID.
DestinationRatesID
The identifier of the :ref:`DestinationRate` set.
TimingID
The itentifier of the :ref:`Timing` profile.
Weight
Priority of matching rule (*DestinationRatesID*+*TimingID*). Higher value equals higher priority.
.. _DestinationRate:
DestinationRate
^^^^^^^^^^^^^^^
Groups together destination with rate profiles and assigns them some properties used in the rating process. Configured via the following parameters:
ID
The tag uniquely idenfying each DestinationRate profile. There can be multiple entries grouped by the same ID.
DestinationsID
The identifier of the :ref:`Destination` profile.
RatesID
The identifier of the :ref:`Rate` profile.
RoundingMethod
Method used to round during float operations. Possible values:
**\*up**
Upsize towards next integer value (ie: 0.11 -> 0.2)
**\*middle**
Round at middle towards next integer value (ie: 0.11 -> 0.1, 0.16 -> 0.2)
**\*down**
Downsize towards next integer (ie: 0.19 -> 0.1).
RoundingDecimals
Number of decimals after the comma to use when rounding floats.
MaxCost
Maximum cost threshold for an event or session.
MaxCostStrategy
The strategy used once the maximum cost is reached. Can be one of following options:
**\*free**
Anything above *MaxCost* is not charged
**\*disconnect**
The session is disconnected forcefully.
.. _Destination:
Destination
^^^^^^^^^^^
Groups list of prefixes under one *Destination* profile. Configured via the following parameters:
ID
The tag uniquely idenfying each Destination profile. There can be multiple entries grouped by the same ID.
Prefix
One prefix entry (can be also full destination string).
.. _Rate:
Rate
^^^^
A *Rate* profile will contain all the individual rates applied for a matching event/session on a time interval. Configured via the following parameters:
ID
The tag uniquely idenfying each *Rate* profile. There can be multiple entries grouped by the same ID.
ConnectFee
One time charge applying when the session is opened.
Rate
The rate applied for one rating increment.
RateUnit
The unit raported to the usage received.
RateIncrement
Splits the usage received into smaller increments.
GroupIntervalStart
Activates the rate at specific usage within the event.
.. _Timing:
Timing
^^^^^^
A *Timing* profile is giving time awarness to an event. Configured via the following parameters:
ID
The tag uniquely idenfying each *Timing* profile.
Years
List of years to match within the event. Defaults to the catch-all meta: *\*any*.
Months
List of months to match within the event. Defaults to the catch-all meta: *\*any*.
MonthDays
List of month days to match within the event. Defaults to the catch-all meta: *\*any*.
WeekDays
List of week days to match within the event as integer values. Special case for *Sunday* which matches for both 0 and 7.
Time
The exact time to match (mostly as time start). Defined in the format: *hh:mm:ss*
.. Note:: Due to optimization, CGRateS encapsulates and stores the rating information into just three objects: *Destinations*, *RatingProfiles* and *RatingPlan* (composed out of *RatingPlan*, *DestinationRate*, *Rate* and *Timing* objects).
.. Accounting:
Accounting
----------
Accounting is the process of charging an *Account* on it's *Balances*. The amount of charges is decided by either internal configuration of each *Balance* or calculated by :ref:`Rating`.
.. _Account:
Account
^^^^^^^
Is the central unit of the :ref:`Accounting`. It contains the following fields:
Tenant
The tenant to whom the account belogs.
ID
The Account identifier which should be unique within a tenant. This should match with the event's *Account* field.
BalanceMap
The pool of :ref:`Balances <Balance>` indexed by type.
UnitCounters
Usage counters which are set out of thresholds defined in :ref:`ActionTriggers <ActionTrigger>`
AllowNegative
Allows authorization independent on credit available.
UpdateTime
Set on each update in DataDB.
Disabled
Marks the account as disabled, making it invisible to charging.
.. _Balance:
Balance
^^^^^^^
Is the unit container (wallet/bundle) of the :ref:`Account`. There can be unlimited number of *Balances* within one :ref:`Account`, groupped by their type.
The following *BalanceTypes* are supported:
\*voice
Coupled with voice calls, represents nanosecond units.
\*data
Coupled with data sessions, represents units of data (virtual units).
\*sms
Coupled with SMS events, represents number of SMS units.
\*mms
Coupled with MMS events, represents number of MMS units.
\*generic
Matching all types of events after specific ones, represents generic units (ie: for each x *voice minutes, y *sms units, z *data units will have )
\*monetary
Matching all types of events after specific ones, represents monetary units (can be interpreted as virtual currency).
A *Balance* is made of the following fields:
Uuid
Unique identifier within the system (unique hash generated for each *Balance*).
ID
Idendificator configurable by the administrator. It is unique within an :ref:`Account`.
Value
The *Balance's* value.
ExpirationDate
The expiration time of this *Balance*
Weight
Used to prioritize matching balances for an event. The higher the *Weight*, the more priority for the *Balance*.
DestinationIDs
List of :ref:`Destination` profiles this *Balance* will match for, considering event's *Destination* field.
RatingSubject
The rating subject this balance will use when calculating the cost.
This will match within :ref:`RatingProfile`. If the rating profile starts with character *\**, special cost will apply, without interogating :ref:`Rating` for it. The following *metas* are available:
**\*zero$xdur**
A *\*zero* followed by a duration will be the equivalent of 0 cost, charged in increments of *x* duration (ie: *\*zero1m*.
**\*any**
Points out to default (same as undefined). Defaults are set to *\*zero1s* for voice and *\*zero1ns* for everything else.
Categories
List of event *Category* fields this *Balance* will match for.
SharedGroup
Pointing towards a shared balance ID.
TimingIDs
List of :ref:`Timing` profiles this *Balance* will match for, considering event's *AnswerTime* field.
Disabled
Makes the *Balance* invisible to charging.
Factor
Used in case of of *\*generic* *BalanceType* to specify the conversion factors for different type of events.
Blocker
A *blocking Balance* will prevent processing further matching balances when empty.
.. ActionTrigger:
ActionTrigger
-------------
Is a mechanism to monitor Balance values during live operation and react on changes based on configured thresholds and actions.
An *ActionTrigger* is made of the following attributes:
ID
Identifier given by the administrator
UniqueID
Per threshold identifier
ThresholdType
Type of threshold configured. The following types are available:
**\*min_balance**
Matches when the :ref:`Balance` value is smaller.
**\*max_balance**
Matches when the :ref:`Balance` value is higher.

ThresholdValue
The value of the threshold to match.
Recurrent
Execute *ActionTrigger* multiple times.
MinSleep
Sleep in between executes.
ExpirationDate
Time when the *ActionTrigger* will expire.
ActivationDate
Only consider the *ActionTrigger* starting with this time.
Balance
Filters selecting the balance/-s to monitor.
Weight
