Benefits

All wireless service providers offer their customer the option to pay in advance for wireless services that will be consumed later. This type of service, called a prepaid wireless service (or prepay) has a number of advantages:

Features

The prepaid account offers the following features:

Implementation Considerations

Consider the following when planning your implementation:

The new order BPEL process (Telco New Order BPEL) coordinates the creation of the installed product and the two billing accounts (CRM and external prepaid). The process then notifies the HLR about the new account, plan, and information.

The process involves the following steps:

  1. Create the CRM account.

  2. Create the installed product in CRM with the status set to eitherPending Call-Activation if shipping is necessary or Pending Auto-Activation if the order was fulfilled at the storefront.

  3. Create an account in the external prepaid billing system with the status set to Activated. Associate it to the CRM account.

  4. If necessary, the fulfillment system fulfills the order.

    If shipping is involved, the Telco New Order BPEL process will end. A separate BPEL process called Telco Activate Service runs when the customer calls in to activate the service.

  5. Assign plan MSISDN numbers to the new account.

  6. Activate on the HLR, the IMSI and MSISDN with the selected plan.

  7. Hotline the service if there are no funds in the account and set the Installed Product status to Pending Top-up. If funds are available set the Installed Product status to Activated.

  8. The customer can add funds and manage the prepaid account either through self-service or by calling into the call center. Changes to the account can also be made externally through the prepaid billing system facilities and will be reflected in the CRM system.

A messaging protocol must be established with the prepaid billing system. Information is retrieved from the prepaid billing system on demand using both synchronous and asynchronous inbound/outbound messaging. The synchronous messages need to be answered for the CRM system to manage the prepaid account.

The asynchronous messaging consists of two inbound XML messages coming from the third-party billing system:

The synchronous messaging consists of several outbound XML messages going to the third-party billing system to retrieve account data for display:

You can designate products to be sold only with a prepaid account, a postpaid account, or with no restriction. For example some services are not available through a prepaid account and some are not available through a normal billing cycle account. Most products are available without restriction.

The billing account type of Prepaid Only, Postpaid Only or Either is established when the product is defined. The Billing Options group box, which allows you to specify the types of accounts that can be used to pay for charges of the product (new or installed), appears only for the communications industry as delivered and is controlled by display templates.

When you save a package the system ensures that the package does not contain services that have both the prepaid and postpaid values. If a mix is found, an error is shown and the package not saved.

Click to jump to parent topicAccount Activation

There are two methods to activate a prepaid service:

Click to jump to top of pageClick to jump to parent topicSingle Activation

In this process a customer purchases a SIM card and phone, usually from a carrier's retail store. The activation of the prepaid service can take place either through an agent at the retail store or through the carrier’s call center .

To activate the service through a storefront:

Note. If the activation takes place through a call center, the order needs to be fulfilled and there is an additional step for the customer since they need to call in and activate the phone.

In the bulk activation process, a range of accounts are pre-created in Pre-Active status, in the prepaid billing system for a range of ICCIDs.

Typically when a bulk load is performed, the Service Plan associated with each ICCID and the starting balance (usually zero) is specified. A prepaid billing account is created for each ICCID. Each billing account has a status of Pre-Active.

Phone kits that include a handset and a SIM(ICCID) with MSISDN can be packaged and sold by retailers. To activate the service the customer purchases a prepaid card and follows the instruction in the box. No contact is required with a customer service representative to activate the prepaid service. However the prepaid customer can contact the call center, or use self-service for post activation support.

Click to jump to parent topicCommon Terminology Used for Prepaid Accounts and Wireless Communication Industry

Subscriber Identity Module (SIM) or SIM Card

The Subscriber Identity Module or SIM is a smart card that contains a Global System for Mobile Communication (GSM) customer’s subscription data. Service is not available without an active SIM card. Each SIM is assigned a unique number, which is known as the SIM number integrated circuit card identity (ICCID). The ICCID identifies the SIM card vendor as well. The ICCID is located on the SIM Card.

International Mobile Subscriber Identity (IMSI)

The IMSI uniquely identifies a subscriber in a GSM network. The IMSI is the primary customer identification element from a network standpoint, not the MSISDN.

The IMSI with a maximum of 15 numeric digits is made of 3 components

  • Mobile Country Code (MCC) – 3 digit code that identifies the end-users home country

  • Mobile Network Code (MNC) – 2 or 3 digit code that identifies the end-users home carrier

  • Mobile Subscriber Identification number – 9-10 digit code that identifies the end-user within the home carrier's systems

Mobile Station International ISDN Number (MSISDN)

The MSISDN is the directory number assigned to a GSM end-user by the network operator. The MSISDN is similar to the Mobile Directory Number (MDN) in the TDMA world. The MSISDN which does not exceed 15 digits, follows the numbering plan specific to the country the carrier is operating in. This is the phone number used with the service. The general format is:

  • CC: Country Code

  • NDC: National significant digit (in the US this would be the NPA, other parts of the world may refer to this as the City Code)

  • SN: Subscriber Number (in the US this would be NXX & Line number, other parts of the world may refer to this as the Exchange + Line number)

International Mobile Equipment Identity (IMEI)

The IMEI is the unique identifier assigned to each GSM mobile device (handset). The device transmits the IMEI when requested. A network operator has an IMEI white list & black list contained in the Authentication Center.

Valid IMEI will be entered into the white list & stolen/fraudulent IMEI will be listed in the Black list. Prior to call connection the Authentication Center will be checked to ensure that the handset making or receiving the call is not on the black list. The IMEI is also stored in the billing system by some network operators. The IMEI is a 15 digit number

Home Location Register (HLR)

The HLR is a network element of a Network. It is a database used for storage and the management of subscriptions. The HLR stores permanent subscriber data such as service profile, location information and activity status. When an end-user is activated, their permanent data (SIM, IMSI, MSISDN and so forth) is entered into the HLR.

Hot-lining

Hot-lining is the process of diverting subscribers from their desired destination to a destination controlled by the service provider. Typically, this means redirecting subscribers from their desired call destination to a call center. In the case of data services this can mean subscribers from their desired web page to another that is specific to the reason the subscribers are being redirected. For prepaid services that have been activated yet have no funds, the phone is hot-lined and phone calls will be diverted to a call center.
