Network Group Price Plans
Accounts, which are configured for Rating Type “Prorated”

Any configured Usage Limit (per SIM and Billing Cycle) does still apply and is independent of any tiering.
Technical Prerequisites
This feature does not require any specific technical integrations for standard operation.
While no direct dependencies apply in typical scenarios, additional integrations or configurations may be necessary depending on the customer's infrastructure, business processes, or regulatory environment.
Functionality of the feature
CMP allows Zone Price Plans to support Tiering. Tiering is a mechanism to control specific Charges and Monthly Included Usage based on the number of active SIM Cards on a Price Plan. Tiering allows configuring multiple levels of pricing and usage, where the correct value for calculation is selected at the end of the Billing Cycle.
Tiering can apply to two different object types in Price Plans:
Price Points (MRC and Overage Price)
Monthly Included Usage
The following principle definitions apply when defining tiers:
Tiers are defined as blocks,
“up to” values have to be defined,
the only exception to that is the last block, which is “unlimited”, and
a maximum of 20 tiers are supported.
Tiers are calculated based on the number of SIMs on that Price Plans, and Tiering supports two different calculation types:
Highest Bucket: At the time of rating all SIMs shall be rated at the highest applicable tier.
Per Tier Bucket: At the time of rating each SIM shall be rated based on the tier they belong to.

Active SIM Cards in relation to tier calculations are considered to be unique SIMs (each SIM can only contribute exactly once per Billing Cycle, no matter how often and when it changed its status), which are assigned to the related Price Plan and are in status In-Billing at the end of the Billing Cycle. There is no minimum obligation, i.e. it does not matter how long the SIM was in status In-Billing or how long it was assigned to the Price Plan.
Further, SIMs in status Suspended are also considered, if the related Price Plan is configured to “grant allowance during suspend” (so the SIM does still contribute to the total pool allowance).
Price Plan Tier Counters have to be increased/decreased in case of the following events:
SIM moves into status In-Billing - increase counter by one
SIM moves out of status In-Billing - decrease counter by one
SIM moves to the Price Plan - increase counter by one
SIM moves out of the Price Plan - decrease counter by one
SIM resides into status Suspended for full Billing Cycle with “grant allowance enabled” - keep counter by one
SIM resides into status Suspended for full Billing Cycle with “grant allowance disabled” - decrease counter by one
Tiering is an option of an individual Price Plan, therefore it can be changed in any Sub-Version, and it can change to a future Version without any tiering.
The Price Plan Tiering feature can be enabled “on-demand”, tiering configuration options in the GUI only become available if the feature is enabled. Note that the tiering configuration option is only available in Zone Price Plans and if the Price Plan configuration is as follows:
Postpaid
Pool
Flex: support MRC and Overage tiering
Fix: support MRC, Overage and Included Usage tiering
Individual: support MRC and Overage tiering
If Price Plan is DEDICATED
The related Account has to be configured accordingly
MRC Charge Type = In Retrospect
Rating Type = Retrospective
If Price Plan is SHARED
Tiering can always be configured
Account MRC Charge Type and Rating Type will be verified when the Price Plan gets assigned to the Account at the Entitlements of that Account
Whenever a Price Plan is assigned to a Master Account via Entitlements, then the Price Plan is being checked for Tiering. In case Tiering is enabled, the MRC Charge Type and Rating Type of the Account gets verified as the Price Plan can only be assigned if the Account is configured to
MRC Charge Type = In Retrospect
Rating Type = Retrospective
