LTE service with content-based billing

Link copied to clipboard

Content-based billing is the business model that allows ISPs to bill customers differently based on the content their customers access. The gateway analyzes the Internet content that users access (e.g., YouTube, social networks, email services, etc.) and sends corresponding rating group values to PortaBilling.

Note that in order to configure rating groups, a gateway that supports Diameter (Gy) is required. This handbook demonstrates the configuration working via the Huawei UGW9811 gateway.

Let’s configure the scenario in which an ISP provides the following Internet traffic types for his LTE users free of charge:

  • Service provider’s hotline website;
  • Social networks;
  • Service provider’s SIP server (for making SIP calls).

Everything else is billed using a standard price.

To do this, an administrator creates and defines rating groups for each type of Internet traffic. The rating groups are divided into two types: billable and cost free. The ISP charges end users $0.01 per megabyte for the billable rating group.

Rating groups can be configured for other services (e.g., 3G, VoIP). Please contact the PortaOne support team for more details.

Use this checklist to check off the operations you have completed while performing the system setup according to the instructions in this chapter. Please be sure to perform all of the operations in the order designated (all of the boxes should be checked), otherwise, the service will not work.

This handbook assumes that you have already configured the basic LTE service including the hotlining section according to the LTE configuration handbook. Please proceed with the steps below to additionally configure the content-based billing.



Define rating groups on your gateway

Adjust the LTE node settings

Create destinations for rating groups in the RGXXX format, where XXX stands for the rating group value

Create a tariff to charge end users for accessing the Internet

Enter rates to the tariff for RGXXX destinations

Insert a rate for the symbolic NETACCESS destination

Create a product for content-based billing. Create a rating entry with the Any code access code within

Create an account for your customer with this product assigned

Configure the gateway

Define the rating groups on the network side (gateway, PCRF, etc.) and assign a unique code to each one of them:

  • Service provider’s hotline website – RG101
  • Social networks – RG102
  • Service provider’s SIP server – RG103
  • Regular web browsing – RG104.
The gateway configuration varies, depending upon the model. Please refer to the gateway documentation for full information about how to define rating groups on any given equipment.

Create destinations

To charge customers for accessing different Internet content, it is necessary to create custom destinations that match the rating group values you have defined earlier on the gateway. Thus, in our example we will create destinations as follows: RG101, RG102, RG103 and RG104.

  1. On the navigation menu, select Service catalog, Rate codes, and then select Destinations.
  2. Open the Create a destination panel and fill in the destination information:
    • Format – select Custom from the list.
    • Prefix – type in RG101.
    • Description – enter useful information about the service being provided (e.g., Hotline), since this is what your clients will see on their xDR History pages.
  3. Click Save.
  4. Repeat steps 2-3 to enter all destinations required (RG102-RG104).

    Create destinations

    Check the destinations created

Create a customer tariff

At this step, it is necessary to create a tariff that will be used to charge your customers for accessing different Internet content.

  1. On the navigation menu, select Service catalog and click Tariffs.
  2. On the Create tariff panel, fill in the tariff details:
    • Name – type in a short name for the tariff object; this is the name you will see in the select menus.
    • Currency – select the currency in which you will charge your customers.
    • Service – select LTE from the list.
    • Applied to – select Customer as this tariff will be used to charge your customers.
    • Managed by – select Administrator only here.
  3. Click Save.

    Create a customer tariff

Enter rates to the tariff

  1. Open the customer tariff "Content billing" and click Rates.
  2. On the Add rate panel, fill in the rate details:
    • Rate code – type in RG101 destination directly or select it from the list.
    • Rating mode – select Flat rate here.
    • Rounding – leave the default “1” value for this example. See more info on the Rounding option in the UI help.
    • Unit price – enter the price per billing unit (in this example, per megabyte).
  3. Click Save.
  4. Repeat steps 1-3 and enter the rate for the NETACCESS destination. This rate will be used to authorize a user and charge for any other rating group.
  5. Repeat steps 1-3 until you have entered rates for all destinations required.

    Enter rates for the customer tariff

Create a product

Accounts for accessing Internet services are issued with the specific products. Products are powerful features that define different ways to bill an account. Product definition is always done in these steps: product definition, service configuration and the creation of a rating list.

  1. On the navigation menu, select Service catalog and click Products.
  2. On the Create product panel, fill in the product details:
    • Name – type in a short name for the product object; this is the name you will then see in the select menus.
    • Name visible to end users – specify the name of this product that your customers will see on their self-care interface.
    • Product type – select Main product here.
    • Currency – choose a currency the product will be priced in.
    • Managed by – select Administrator only here, since we are setting up a service without the involvement of resellers.
    • Account default ACL – choose an Access Control List (ACL) for accounts with this product assigned. ACLs control which objects end users can access to and which actions they can perform.
    • Account role – select Mobile to associate this product with mobile subscribers.
  3. Click Save.

  2. On the Usage charges panel, click Add.
  3. Fill in the required information:
    • Service – select LTE.
    • Node – select the LTE node.
