Abstract
The present invention provides a method and a system for a plurality of phones just one number co-ringing service, and the method includes the following: a call request is received by AS from a calling terminal, then the call request is retransmitted to each called terminal with media description information of a common conversation from the calling terminal and a signal of supporting an early-media conversation; the media description information of the common conversation from the own terminal and media description information of the early-media conversation is transmitted to AS after each called terminal receiving the call request; the media description information of the early-media conversation from the called terminal is modified by AS, and the modified media description information is fed back to the corresponding called terminal, a ringing message is transmitted to the calling terminal; a called terminal is learned by AS after hanging on a call, then other called terminals are advised to hang up, and the media description information of the common conversation from the called terminal after hanging up is transmitted to the calling terminal, so the calling and the called can communicate. The present invention simplifies and standardizes the realization of a plurality of phones just one number co-ringing service, and effectively solves the matter of media packet loss caused by media switch in existing services.
Description
Technical field
The present invention relates to realize in the NGN network method and system of a multimachine simultaneous ringing service.
Background technology
A multimachine is very characteristic business in the NGN network (next generation network), the service feature of this business is, with a plurality of physical terminals and a number bundling together, when this number of calling user dials, application server goes to call out a plurality of terminals that are associated with this number simultaneously or calls out a plurality of terminals, just usually said simultaneous ringing service or sequential ringing service in a certain order successively.At present, the typical characteristic service of carrying out in the NGN network comprises one number service and two phones just one number business, and the service logic of the two is in full accord.The difference of the two is: in one number service, the terminal number that is associated with the one number service number can have a plurality of; And the two phones just one number business is that user's landline telephone and PAS terminal are associated with on the number simultaneously, so terminal number has only two.
For the business of a multimachine class, service logic comprises that the realization of service logic is identical with shaking and two kinds of business of CSC.Especially, for simultaneous ringing service, when User Agent Client (UAC:UserAgent Client) is sent to User Agent Server (UAS:User Agent Server) with call request, UAS as application server need go to call out a plurality of terminals simultaneously, " bifurcated (fork) " this more typical call model occurred.Processing for this call model, different application server processes patterns have nothing in common with each other, and what is more important, and application server must have initiates the operation that a time medium switch, could guarantee after the terminal off-hook normal talking between caller and this terminal.And this medium handover operation can cause losing of called voice sheet usually, influences speech quality.
Figure 1 shows that the signaling process flow chart of realizing the two phones just one number simultaneous ringing service in the prior art.Process description is as follows:
Step 101: calling UE-a makes a call, and AS (application server, Application Server) receives INVITE (call request), wherein carries caller SDP-a (media description information);
Step 102:AS sends 100TRYING (message and preparation processing such as Invite are received in representative) to UE-a;
Step 103:AS rewrites SDP-a, changes the medium link address into 0.0.0.0, forms SDP-a ', sends INVITE to called UE-b and called UE-c then, wherein carries SDP-a ';
Step 104:AS receives the 100TRYING that UE-b and called UE-c send;
Step 105:AS receives 180 message (ALERTING message) of UE-b, returns the 200OK (response) that PRACK (acknowledging receipt of 180 message) receives that afterwards UE-b sends to UE-b, finishes reliable 180 reply;
AS receives 180 message of UE-c, receives the 200OK that UE-c sends after UE-c returns PRACK, finishes reliable 180 reply;
Step 106:AS sends 180 message to calling UE-a, sends 200OK to it after receiving the PRACK that UE-a sends, and finishes reliable 180 reply;
Step 107: supposition called UE-c elder generation off-hook, AS receives the 200OK message (response message) that UE-c sends, and carries SDP-c this moment;
Step 108:AS sends ACK (acknowledge message) to UE-c;
Step 113:AS sends RE-INVITE to UE-c, carries SDP-a;
Step 114:AS receives the 100TRYING that UE-c sends;
Step 115:AS receives that the 200OK that UE-c sends replys, and wherein carries SDP-c;
Step 116:AS sends ACK to UE-c;
Step 117:AS returns 200OK to calling UE-a, wherein carries SDP-c;
Step 118:AS receives the ACK that UE-a sends;
After this, calling and called enter talking state.
Summary of the invention
