Abstract
The embodiment of the invention discloses a method, equipment and a system for centralized billing. The method comprises the following steps that: when a user in an IP (Internet Protocol) multimedia subsystem initiates a call, an interconnecting device between the IP multimedia subsystem and a public switched telephone network routes the call to a billing center in the public switched telephone network to be subjected to centralized billing; the interconnecting device receives a billing instruction which is used for making a call free receipt and is transmitted by the billing center in the public switched telephone network in a signaling format supported by the public switched telephone network; and the interconnecting device converts the billing instruction into the signaling format supported by the IP multimedia subsystem and subsequently transmits to a billing network element in the IP multimedia subsystem, so that the call free receipt for the call initiated by the user is generated through the billing network element. Therefore, an IMS (IP Multimedia Subsystem) is enabled to have the capability of carrying out networked billing with a PSTN (Public Switched Telephone Network) in the process that the PSTN is evolved to a uniform IMS network.
