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.
Claims18
A method comprising:
- receiving, by a session management function (SMF) from an access and mobility management function (AMF), a packet data unit (PDU) session create request message requesting establishment of a PDU session for a wireless device;
- sending, by the SMF to a charging function (CHF) and in response to the PDU session create request message, a charging policy request message requesting charging policy information for the PDU session;
- receiving, by the SMF from the CHF, a response message comprising the charging policy information for the PDU session, wherein the charging policy information comprises:
- a first charging method;
- and
- an information element indicating that a first charging rate is applicable for the PDU session;
- determining, by the SMF based on the charging policy information, a charging control rule for the PDU session;
- and
- enforcing, by the SMF, the charging control rule.
A method comprising:
- receiving, by a session management function (SMF) from an access and mobility management function (AMF), a packet data unit (PDU) session create request message requesting establishment of a PDU session for a wireless device;
- sending, by the SMF to a charging function (CHF) and in response to the PDU session create request message, a charging policy request message requesting charging policy information for the PDU session;
- receiving, by the SMF from the CHF, a response message comprising the charging policy information for the PDU session, wherein the charging policy information comprises a first charging method;
- determining, by the SMF based on the charging policy information, a policy and charging control (PCC) rule for the PDU session, wherein the PCC rule comprises at least one of:
- a charging control rule, wherein the charging control rule further comprises at least one of:
- an information element indicating a second charging method;
- an information element indicating a second charging rate;
- or
- an information element indicating an identifier or address of a second CHF;
- a policy control rule comprising a QoS control rule;
- a policy control rule comprising a gating control rule;
- a usage monitoring control rule;
- an application detection and control rule;
- a traffic steering control rule;
- or
- a service data flow detection information;
- and
- enforcing, by the SMF, the charging control rule.
A method comprising:
- receiving, by a session management function (SMF) from an access and mobility management function (AMF), a packet data unit (PDU) session create request message requesting establishment of a PDU session for a wireless device;
- sending, by the SMF to a charging function (CHF) and in response to the PDU session create request message, a charging policy request message requesting charging policy information for the PDU session;
- receiving, by the SMF from the CHF, a response message comprising the charging policy information for the PDU session, wherein the charging policy information comprises a first charging method;
- determining, by the SMF based on the charging policy information, a charging control rule for the PDU session;
- and
- enforcing, by the SMF, the charging control rule, wherein the enforcing the charging control rule by the SMF comprises:
- sending, by the SMF to the CHF, a charging data request message requesting to establish a charging session, the charging data request message comprising a requested charging method indication;
- and
- receiving, by the SMF from the CHF, a charging data response message comprising an accepted charging method indication.
