Abstract
A charging method includes: determining, by a control plane function entity (CP), that a data flow that is transmitted by user equipment (UE) on a first data session needs to be migrated to a second data session; charging, by the CP, the data flow on the first UP through a first charging session between the CP and a charging system; obtaining, by the CP, charging information of the data flow before the migration that is counted by the first UP; and determining, by the CP, a quota that is used for the data flow after the migration is necessary to be delivered to the second UP, and delivering the quota to the second UP, thereby charging a service data flow of a user in a case of migration between user planes.
Claims25
A method, comprising:
- determining, by a control plane function entity (CP), that a data flow of a user equipment (UE) being transmitted by a first user plane function entity (UP) needs to be transmitted by a second UP, wherein the data flow is transmitted through a protocol data unit (PDU) session that is established between the UE and a data network that provides a PDU connection service, the first UP and the second UP are connected to the data network, and the first UP and the second UP are selected by the CP;
- receiving, by the CP via an interface between the CP and the first UP, usage information for a first quota, wherein the first quota is requested by the CP from a charging system, and the usage information of the first quota is counted by the first UP and reported to the CP by the first UP;
- determining, by the CP based on the first quota and the usage information of the first quota, a second quota for the second UP to use for transmitting the data flow, wherein the second quota is based on a remaining available quota of the first quota;
- and
- delivering, by the CP via an interface between the CP and the second UP, the second quota to the second UP.
