  • Patent number: 9055083
    Abstract: The present invention discloses a method for implementing simulation services, including the following: an interworking control unit obtains the CS domain network user identifier after detecting that the call signaling message from the CS domain network carries no CS domain network user identifier, puts the obtained user identifier into the SIP message, which is subsequently sent to the IMS network; the IMS network processes the PSTN/ISDN simulation services according to the user identifier. The present invention also discloses a system for implementing simulation service. The present invention makes it unnecessary to extend the existing SIP protocol and to perform signaling interaction between the IMS network and the interworking control unit for obtaining the user identifier, thus simplifying the implementation of the PSTN/ISDN simulation services.

  • Patent number: 8335221
    Abstract: A method for listening to signal tone from a called party by a calling party during network interworking. When the media gateway control unit receives an Address Complete message or Call Progress message from the circuit domain network, the media gateway control unit instructs a media gateway to open a media stream channel. If the received message carries an indicator indicating the called party is free, the media gateway control unit sends a Ringing response message to the packet core network; if the received message does not carry a indicator indicating the called party is free, the media gateway control unit sends a response message carrying indicator of failed call but successful media stream setup or a response message indicating failed call but successful media stream setup to the packet core network. With the method according to the embodiments of the present invention, the calling party may hear ring-back tone indicating successful call, or signal tone or voice announcement indicating failed call.
