Abstract
Embodiments of this application provide a charging method. The method includes that a session management function determines, a data flow within a protocol data unit, PDU, session and a charging key corresponding to the data flow within the PDU session, wherein a plurality of user plane functions are involved in the PDU session. For each of the plurality of user plane functions, the session management function sends to an online charging system, a quota request for a charging key without available quota for the UPF.
Claims19
A method comprising:
- determining, by a session management function, a data flow associated with each of a plurality of user plane functions involved in a protocol data unit (PDU) session, and a charging key corresponding to the data flow in the PDU session;
- and
- sending, by the session management function to an online charging system, a quota request for a first user plane function of the plurality of user plane functions, the quota request requesting grant of a first quota for a first charging key lacking an available quota, with the first charging key corresponding to a first data flow associated with the first user plane function of the plurality of user plane functions, receiving, by the session management function, the first quota granted by the online charging system to the first charging key for the first user plane function, and delivering, by the session management function, the granted first quota for the first charging key to the first user plane function.
A method comprising:
- receiving, by an online charging system from a session management function, a quota request for a first user plane function of a plurality of user plane functions involved in a protocol data unit (PDU) session, the quota request requesting grant of a first quota for a first charging key lacking an available quota, with the first charging key corresponding to a data flow that is in the PDU session and that is associated with the first user plane function;
- and
- sending, by the online charging system to the session management function, the first quota granted to the first charging key lacking the available quota.
A computing device, comprising a processor, a memory, a bus, and a communications interface, wherein the memory is configured to store a computing-device executable instruction, the processor is connected to the memory by using the bus, and when the computing device operates, the processor executes the computing-device executable instruction stored in the memory, so that the computing device performs following steps:
- determining a data flow associated with each of plurality of user plane functions involved in a protocol data unit (PDU) session, and a charging key corresponding to the data flow in the PDU session;
- and
- sending, to an online charging system, a quota request for a first user plane function of the plurality of user plane functions, the quota request requesting grant of a first quota for a first charging key lacking an available quota, with the first charging key corresponding to a first data flow associated with the first user plane function of the plurality of user plane functions, receiving the first quota granted by the online charging system to the first charging key for the first user plane function, and delivering the granted first quota for the first charging key to the first user plane function.
A network system, comprising a charging device and a charging system, wherein:
- the charging device is configured to determine a data flow associated with each of plurality of user plane functions involved in a protocol data unit (PDU) session, and a charging key corresponding to the data flow in the PDU session, send, to the charging system, a quota request for a first user plane function of the plurality of user plane functions, the quota request requesting grant of a first quota for a first charging key lacking an available quota, with the first charging key corresponding to a first data flow associated with the first user plane function, receive the first quota granted by the charging system to the first charging key for the first user plane function, and deliver the granted first quota for the first charging key to the first user plane function;
- and
- the charging system is configured to receive the quota request requesting the grant of the first quota for the first charging key, and send the first quota granted to the first charging key to the first user plane function.
