Embodiment
Below in conjunction with accompanying drawing the preferred embodiments of the present invention are described, should be appreciated that preferred embodiment described herein only is used for explanation and explains the present invention, and be not used in qualification the present invention.
Method embodiment
TD-CS multimedia group multimedia ring service is to utilize existing traditional CS territory network to realize the business in the IP network; It is a kind of called service; When calling is called, should business like called having opened, called terminal can be shown to the calling subscriber to the image that network sends.The multimedia file that this image is provided with by the called subscriber is in advance play generation, and the kind of multimedia file can be audio frequency, video and picture.
In the present embodiment, a kind of group multimedia ring service implementation method is provided, has been used for playing the group CRBT that terminal called is provided with to calling terminal, Fig. 1 is the flow chart according to the group multimedia ring service implementation method of the embodiment of the invention.
At first; Caller video gateway (VIG) obtains the call request based on circuit domain (CS) agreement that calling terminal sends via calling mobile exchanging center (MSC); And caller VIG is to changing based on the call request of CS agreement; Convert the call request of IP based network agreement into, and the call request of the IP based network agreement after will changing sends to server of color ring back tone service (AS).Next, proceed to following processing as shown in Figure 1:
Step S102, AS obtain the call request from the IP based network agreement of caller VIG, and the call request of IP based network agreement is forwarded to called VIG;
Step S104; Called VIG changes the call request of IP based network agreement, converts the call request based on the CS agreement into, and the call request based on the CS agreement after will changing is routed to terminal called; Wherein, carry the Ring Back Tone service access code in the call request based on the CS agreement;
In step S104, the call request of the IP based network agreement after called VIG will change is routed to terminal called and is specially: 1, called VIG will send to called MS C based on the call request of CS agreement; 2, called MS C will send to terminal called based on the call request of CS agreement, and behind the response message based on the CS agreement that receives the terminal called transmission, will be forwarded to called VIG based on the response message of CS agreement; 3, called VIG is behind the response message based on the CS agreement that receives called MS C transmission; To changing based on the response message of CS agreement; Convert the response message of IP based network agreement into, and the response message of the IP based network agreement after will changing sends to AS.
Step S106, AS trigger group multimedia ring service based on the group CRBT attribute of terminal called.
The operation of step S106 can be specially: 1, the CAMEL-Subscription-Information of AS inquiry terminal called, and definite terminal called has group multimedia ring service; 2, after AS triggered group multimedia ring service according to the Ring Back Tone service access code, Query Database obtained played color ring resource file type, and carries out playing flow according to CRBT resource file type.
Wherein, above-mentionedly carry out playing flow according to CRBT resource file type and be specially:
1, is under the situation of audio frequency and/or video in CRBT resource file type, carries out the media negotiating process of media server (MS) and calling terminal; 2, be under the situation of picture in CRBT resource file type, obtain the address of picture, and be issued to calling terminal; 3, after the calling terminal playing back group color ring, calling terminal and terminal called carry out video calling.
In addition, before the video calling that carries out above-mentioned calling terminal and terminal called, also comprise following processing:
1, terminal called initiates to set up call control protocol passage process to called VIG; 2, called VIG sends the response message of IP based network agreement to AS, and in the response message of IP based network agreement, carries the media information of called VIG; 3, AS sends the call request again of IP based network agreement to caller VIG, and in the call request again of IP based network agreement, carries the media information of called VIG; 4, caller VIG sends the response message of IP based network agreement to AS, and in the response message of IP based network agreement, carries the media information of final negotiation; 5, AS transmits the response message of IP based network agreement to called VIG; 6, calling terminal and terminal called are accomplished media negotiation, carry out video calling.
According to technique scheme, can realize the video multimedia CRBT.
Need to prove in addition, state in realization before the processing, need upload, specify the process that multimedia color ring back tone is uploaded below multimedia color ring back tone.
The webserver uploads to CRBT file in the FTP file of the webserver, and sends the request message upload CRBT to interface message processor (IMP), wherein, uploads in the request message of CRBT and carries webserver information; In response to the request message of uploading CRBT, interface message processor (IMP) is carried out the storing process of CRBT file in the database of AS, upload desired parameters to obtain CRBT file; After the database of AS returned execution result, interface message processor (IMP) uploaded to CRBT file in the NFS of MS.
Below, in conjunction with accompanying drawing, above-mentioned multimedia group CRBT file loading process being carried out the message explanation, Fig. 2 is the signaling process figure according to the multimedia group CRBT file loading process of the embodiment of the invention, and is as shown in Figure 2, comprises following processing:
Step 202, group management person or SP keeper land the WEB page, the wav file that selection will be uploaded, fill in relevant multimedia bell information, and select to upload;
Step 204, WEB server upload to CRBT file on the ftp server of WEB;
Step 206, the WEB server sends the request of uploading CRBT to interface message processor (IMP), has the WEB server info in the request message;
Step 208, interface message processor (IMP) is carried out storing process at the database of server of color ring back tone service, uploads desired parameters to obtain CRBT;
Step 210, the database of server of color ring back tone service returns execution result;
Step 212, interface message processor (IMP) downloads to the ftp server of CRBT file from WEB the temporary folder of interface message processor (IMP);
Step 214, interface message processor (IMP) uploads to CRBT file on the networking file system (Network File System abbreviates NFS as) that media server has from temporary folder;
Step 216, media server are returned to interface message processor (IMP) and are uploaded success message;
Step 218, interface message processor (IMP) will be uploaded information and send to server of color ring back tone service, and after the triggering business, Service Processing Module is with this expense of uploading record and call list;
Step 220, Service Processing Module turns back to interface message processor (IMP) with the result;
Step 222, interface message processor (IMP) will be uploaded message of successful and return to the WEB server;
Step 224, WEB server notification group management person or SP keeper, this CRBT file is uploaded success.
Through above-mentioned processing, can realize uploading of multimedia color ring back tone.
Instance 1
