Configuring a Prepaid Billing Plan

A billing plan identifies one or more content billing services to be used for prepaid billing.

To define a billing plan, perform this task:

	Command	Purpose
Step 1	Router (config-csg-module)# ip csg billing billing-plan-name	Defines a billing plan to be used for prepaid billing, and enters CSG billing configuration mode.
Step 2	Router (config-csg-billing)# service service-name	Associates a service with a CSG billing plan.
Step 3	Router # show module csg slot billing [detail] {all | plan billing-plan-name}	Displays statistics and counters for the CSG billing.

The following example shows how to define a prepaid billing plan:

ip csg billing REGULAR

 service MOVIES

 service BROWSING

When a CSG prepaid user initiates a new IP session, a large amount of quota may be reserved for the IP session if the IP session maps to a service configured for basis byte ip or basis byte tcp. Often, the reservation greatly exceeds the amount of quota that the session actually uses. This does not result in incorrect charging; however, as a result of one or more large reservations for IP sessions, the CSG might make additional requests for quota from the quota server.

Prior to this enhancement, the CSG would limit the reservation size to the size of the intermediate byte count, which resulted in additional records sent to the BMA. Now, you can limit the size of the reservation per IP session to reduce the number of requests to the quota server.

To configure a maximum amount of quota reserved for a prepaid IP user session, configure the following in module CSG configuration mode:

Router (config-module-csg)# variable CSG_BASIS_BYTE_RESERVED_MAX quota
