Prepaid Billing in ECS

In a prepaid environment, the subscribers pay for service prior to use. While the subscriber is using the service, credit is

deducted from subscriber's account until it is exhausted or call ends. The prepaid charging server is responsible for

authorizing network nodes (PDSNs and HAs, or GGSNs) to grant access to the user, as well as grant quotas for either

time connected or volume used. It is up to the network node to track the quota use, and when these use quotas run low,

the network node sends a request to the prepaid server for more quota.

If the user has not used up the purchased credit, the server grants quota and if no credit is available to the subscriber the

call will be disconnected. ECS and DCCA manage this functionality by providing the ability to set up quotas for

different services.

Prepaid quota in ECS is implemented using RADIUS and DCCA as shown in the following figure.
