METHOD FOR REAL-TIME CHARGING, GATEWAY AND DEVICE FOR REAL-TIME CHARGING

摘要

Embodiments of the present invention provide an online charging method, a gateway device, and an online charging device. The online charging method includes: sending, by a control plane entity of a gateway device, a service identifier to a user plane entity of the gateway device, where the service identifier is used by the user plane entity of the gateway device to establish a first session, which is associated with a service, with an online charging system according to the service identifier and perform charging interaction on the first session, and the first session is a session between the user plane entity of the gateway device and the online charging system. According to the present invention, the first session is established between the online charging system and the user plane of the gateway device by using the service identifier, so that direct interaction between the user plane of the gateway device and the online charging system is implemented, and a technical problem that a gateway device in a decoupled architecture has an extremely long charging path and a large charging delay is resolved.
