    In the mobile network, it is important to have detailed and accurate monitoring of service usage on the MobileNext Broadband Gateway so that proper charging information can be generated for millions of customers. In the Third-Generation Partnership Project (3GPP), there are three distinct aspects to the process that translates service use into a bill for services. These aspects are charging, rating, and billing. Charging gathers statistics about service usage for each customer. Rating is the process of determining how much each service costs each particular customer, based on the services contracted or tariffed. Billing is the process of actually generating the customer’s invoice for services.

    The broadband gateway is the anchor of the data call and contains most of the subscriber context information. The broadband gateway is responsible for collecting charging information related to the external data network usage and to network resource usage on the gateway GPRS support node (GGSN) or Packet Data Network Gateway (P-GW), including the amount of data categorized by quality of service (QoS), the user protocols, and the usage of the packet data protocol address. Packet data volume in both the uplink (from the Gn-to-Gi interface) and downlink (from the Gi-to-Gn interface) directions is counted separately.

    The broadband gateway provides support for billing through offline charging, RADIUS accounting, or both. RADIUS accounting delivers accounting information used for billing to the RADIUS accounting server.
