The disclosure discloses a method and system for simultaneous ringing and group-calling in a Click To Dial (CTD) service for solving the problem of failure to implement simultaneous ringing and group-calling in an existing CTD service. With the disclosure, a CTD Application Server (CTD AS) performs signalling control, and extension is made from one logic callee to multiple logic called users, such that calling of multiple logic callees can be initiated simultaneously, the multiple logic callees receiving the call ring simultaneously, and once a logic callee picks up the call, the logic callee may have a phone call with the logic caller, and meanwhile any other logic callee not picking up the call is cancelled. The disclosure implements simultaneous ringing and group-calling in a CTD service, expands the function of an existing CTD service and meets various user demands. |
