Use Case Summary

Purpose

UC 1

Setup products for service fees & usage

  • Ability to charge one-time and recurring service fees

  • Ability to allocate charges for rated CDRs to the correct account

    • Provisioning of usage identifier, e.g. Toll Free number, Trunk group ID etc.

  • Ability to specify included quota e.g. included minutes or data usage amount for each product type (optional)

  • Ability to rate and charge for inbound toll free calls

UC 1 - Setup products for service fees & usage

The example below is specific to configuring a toll free product, setup steps for the trunk group product will be similar however. Notes are included for trunk group setup after the description provided for the toll free product.

Sample Offering for the toll free number product

  • Setup fee (one-time, optional): $10.00

  • Recurring fee (monthly, non-optional): $17.99

  • Included inbound minutes (monthly, optional): 100 minutes

Modeling of service/fees in product catalog

Each toll free number will be modeled as a package within the product catalog. Each package will include services for charging of applicable fees.

If the customer orders multiple toll free numbers e.g. ten numbers, then ten account packages will need to be added to their account, one for each toll free number.

If you are unfamiliar with configuring packages an services refer to following article Package with Recurring and One Time Charges Configuration Example.

Sample Services that will be included in package based on above offer are listed in table below

Note: For setup of trunk products, a similar approach can be used e.g.

Sample Offer for trunk product (e.g. SIP trunk)

  • Setup fee (one-time, optional): $10.00 (modeled as NRC service, non usage based service)

  • Recurring fee (monthly, non-optional): $17.99 (modeled as MRC service , usage based service)

  • Number of channels: 30 (this is a provisioning related parameter which is typically an information only parameter from billing perspective, this can be captured as a custom field on package or service or built into service name e.g. “SIP_Trunk_30 MRC”

The identifier for trunk e.g. TrunkGroupId can be captured under the recurring fee service under the “UsageIdentifier” field

UC 2 - Setup rate plans

Rate plan structure overview is as below.

Each usage class is assigned a rate, each rate is contained within a rate group and rate groups are added to a rate plan that is assignable to an account package.

Mediation rules need to be setup to classify CDRs under the appropriate usage classes e.g. Interstate, Intrastate, International, Local and inbound toll free call types.

Note: The toll free number subscribed by customer is expected to be available in the CDR, either in the called number field or in a separate field in case the called number in CDR is the ring-to (translated) number.

Sample Usage Classes and mediation rules

Usage classes can be configured in the Setup menu and derived based on mediation rules depending on rating/charging requirements. This requires mediation feed configuration to determine the applicable usage class for CDRs.

Usage Class

Sample usage class determination rule

ITFS - Interstate

This usage class will apply if the service location is in the United States and the State for calling number and toll free number is different.

Note: ITFS = Inbound Toll Free Service.

ITFS - Intrastate

This usage class will apply if the service location is in the United States and the State for calling number and toll free number is the same.

ITFS - International

This usage class will apply if the country for calling number and toll free number is different.

ITFS - National

This usage class will apply if the country for calling number and toll free number is the same.

Note: Additional usage classes can be defined for outgoing calls, the table above is provided as a sample for inbound toll free usage classes. Some samples are included below, it’s not an exhaustive list, new usage classes can be introduced flexibly as required based on project specific rating requirements.

Usage Class

Sample usage class determination rule

Interstate - Outbound

This usage class will apply if the calling and called number are within the United States and located in different states.

Intrastate - Outbound
