Abstract

A PCF receives from an SMF, a policy establishment request message requesting a charging control rule for a PDU session of a wireless device. In response to the policy establishment request message, the PCF sends to a CHF a charging policy request message requesting charging policy information for the PDU session. The PCF receives from the CHF a charging policy response message. The charging policy response message comprises the charging policy information. The charging policy information comprises a first charging method. Based on the charging policy information, the PCF determines a charging control rule for the PDU session. The PCF sends to the SMF a policy establishment response message comprising the charging control rule. The SMF enforces the charging control rule.
