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.
Claims22
A method comprising:
- determining, by a session management function, for a first user plane function of a plurality of user plane functions involved in a protocol data unit session, a charging key of a data flow;
- and
- sending, by the session management function to an online charging system, a quota request for the first user plane function of the plurality of user plane functions, the quota request requesting a first quota for a first charging key, wherein the first charging key corresponds to a first data flow associated with the first user plane function of the plurality of user plane functions, and the quota request comprises an identifier of the first user plane function and the first charging key;
- receiving, by the session management function, the first quota from the online charging system for 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 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 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:
- receiving, from a session management function, a quota request for a first user plane function of a plurality of user plane functions that involve 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, wherein the first charging key corresponds to a data flow that is in the PDU session and that is associated with the first user plane function, the quota request comprises an identifier of the first user plane function and the first charging key;
- and
- sending to the session management function, the first quota granted to the first charging key lacking the available quota.
A system comprising:
- a plurality of user plane functions, configured to involve in a protocol data unit session, and to transfer a data flow in the protocol data unit session;
- and
- a session management function, configured to determine, for a first user plane function of the plurality of user plane functions involved in the protocol data unit session, a charging key of the data flow to send, to an online charging system, a quota request for the 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 wherein the first charging key corresponds to a first data flow associated with the first user plane function of the plurality of user plane functions, the quota request comprises an identifier of the first user plane function and the first charging key, and to receive the first quota from the online charging system for the first charging key for the first user plane function.
A method, comprising:
- determining, by a session management function, for a first user plane function of a plurality of user plane functions involved in a protocol data unit session, a charging key of a data flow;
- sending, by the session management function, to an online charging system, a quota request for the 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, with the first charging key of a first data flow associated with the first user plane function of the plurality of user plane functions, and the quota request comprising an identifier of the first user plane function and the first charging key;
- and
- sending, by the online charging system, the first quota for the first charging key for the first user plane function.
