Broadband-specific support for PCEF

The policy and charging enforcement function (PCEF) is supported for broadband-specific functionality. PCEF is one of the major components of the 3rd Generation Partnership Project (3GPP) policy and charging control (PCC) architecture that provides the unification of wireline provisioning and accounting for customers. PCEF provides user traffic handling and CoS at the gateway, provides service data flow detection, and applies the rules received from the Policy and Charging Rules Function (PCRF). PCEF optionally interacts with the Online Charging System (OCS) using the 3GPP Gy protocol to retrieve policy and charging authorization for quotas and credit control. BPCEF configuration consists of configuring the characteristics of the PCRF and OCS with which it interacts. Include the pcrf statement at the [edit access] hierarchy level to configure the PCRF partition and the global attributes, rules, and parameters to authorize and provision subscribers. Include the ocs statement at the [edit access] hierarchy level to configure the OCS global attributes and partition. Include the provisioning-order pcrf statement at the [edit access profile profile-name] hierarchy level to request provisioning from the PCRF over the Gx protocol. Include the charging-service-list ocs statement at the [edit access profile profile-name] hierarchy level to configure the list of charging services to be communicated. Use these new commands to display PCRF and OCS information: show network-access pcrf state, show network-access pcrf statistics, show network-access ocs state, and show network-access ocs statistics. Use these new commands to clear statistics and subscriber counters: clear network-access pcrf statistics, clear network-access pcrf subscribers, and clear network-access ocs statistics.
