Embodiment Construction

[0071] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0072] The present invention provides a method for IMS online charging. The difference between this method and the existing IMS online charging method is that the IMS online charging method of the present invention includes: the IMS gateway functional entity IMS-GWF confirms the user's local The second call has been connected; and after the IMS-GWF confirms that the call has been connected, the step of notifying the online charging system to start charging control for the user. The IMS online charging method of the present invention does not immediately notify the online charging system to perform charging after the IMS-GWF receives the session establishment response message from the S-CSCF, but adds that the IMS-GWF confirms whether the user's curre...

Abstract

The invention discloses an IMS online-charging method and an IMS gateway device. The method comprises the following steps of: confirming that the call of a user is connected by an IMS gateway functional entity; and after confirming that the call of a user is connected, informing an online-charging system to start the charge control of the user by the IMS gateway functional entity. The technical proposal of the method improves an IMS online-charging process, increases the handling of session establishment confirmation conditions, overcomes the drawbacks of the prior IMS online-charging processand avoids mischarging the user when the call is not connected.

Description

technical field [0001] The invention relates to the communication field, in particular to an IMS online charging (Online Charging) method and an IMS gateway device. Background technique [0002] IP Multimedia Core Network Subsystem (IMS) is a next-generation network standard defined by the 3rd Generation Partnership Project (3GPP). Its notable feature is the use of Session Initial Protocol (Session Initial Protocol) , referred to as SIP) system, communication has nothing to do with access, and can have multiple capabilities such as separation of multimedia service control functions and carrying capacity, separation of calls and services, separation of applications and services, separation of services and networks, and integration of mobile network and Internet services. [0003] The IP multimedia subsystem provides online charging services. figure 1 It is a schematic diagram of the framework of the IMS online charging system in the prior art. The whole framework includes U...
