<p>A method for realizing multi-party call, includes the steps of: the operation is transmitted to SSP from SCP (S201), the operation sets the additional number group and the synchronous ringing delay parameter and encodes the additional number group, in which the additional number group includes multiple additional called numbers used to indicate the destination address while the multi-party call is originated; the synchronous ringing delay parameter is used to indicate the calling sequence of the additional called numbers and the delay in the calling period when multi-party call is originated; after received the operation, the SSP originates the call to said multiple additional called numbers according to the calling sequence of the additional called numbers indicated by their synchronous ringing delay parameter and the delay in the calling period (S202). The present invention can realize multi-party call synchronously and enhance the calling ability of the INAP, and the change of the exit intelligent network is small, the service process is simple and easy to realize it.</p> |
