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.
Claims20
A method, comprising:
- determining, by a control plane function entity (CP), that a data flow being transmitted by user equipment (UE) on a first data session needs to be migrated to a second data session, wherein the first data session is between the UE and a first user plane function entity (UP), the second data session is between the UE and a second UP, the first UP and the second UP correspond to the CP, and the first data session and the second data session correspond to a same protocol data unit (PDU) session;
- obtaining, by the CP, charging information of the data flow before the migration, wherein the charging information of the data flow before the migration is counted by the first UP;
- determining, by the CP, a first quota for the data flow after the migration, wherein the first quota is to be delivered to the second UP;
- and
- delivering the first quota to the second UP.
