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