During video alerting, use at SGSN/GGSN 16 and call out to send the SVD data channel that distributes between the travelling carriage 11.This is because the video data size of video alerting is bigger, thereby the control signal of handling among traditional MSC13 can not provide the message of enough transmission videos.
Calling out the video that shows on the screen that sends travelling carriage 11 should be that form is simple, for example can show the small echo video (wavelet video) of small size natural video frequency and the video of simple image service (SIS).SIS is the service of transmission/reception simple image (Tathagata is from the symbol and the image of cartoon).Opened this service in Korea S at present.Have Motion Picture Experts Group (MPEG)-4 function if call out transmission travelling carriage 11, then can play the MPEG video.Each travelling carriage 11 or 18 has the LCDs (LCD) of different video processing functions and different size and color.Therefore, video alerting server 17 should be managed these differences.
Some travelling carriages 11 and 18 can send flow data.These travelling carriages 11 and 18 can have the ability to send and reception natural video frequency (natural video).That is, they can handle the data of 3GPP standard multimedia form (as MPEG layer 4 (MP4) form and 3GP form).
If callee's travelling carriage has the ring sound of setting, its simultaneously processing audio data and video of sending from video alerting server 17 then.That is, during ring up, the voice data (being called the service of sound CRBT) that the callee is set up sends to calling transmission travelling carriage 11 with the video of setting up in advance.The service that sends voice data (being sound) is called the voice frequency ringing service, also can be called the service of sound CRBT.Can be independent of the video alerting service provides voice frequency ringing to serve to calling out transmission travelling carriage 11.
With reference to Fig. 2 the 3G-324M agreement is described below.
The 3G-324M agreement is to be used for replenishing that ITU-T is defined, the standard of the H.324 standard of the visual telephone that is used for cable network.The 3G-324M agreement is by the 3GPP definition of carrying out the work of UMTS mobile communication standard.In other words, 3G-324M definition video/audio codec, multiplexed, host-host protocol and self adaptation (adaptation).
H.263 the Video Codec of 3G-324M defines basically, and additionally recommends MPEG-4.The audio codec of 3G-324M has defined adaptive multi-rate (AMR) codec, and the latter is the basic codec of 3GPP definition.
Because 3G-324M is the video telephony protocols of circuit network, so 3G-324M is based on the multiplexed and multichannel demultiplexing of H.223 execution of ITU-T definition.Based on the control of H.245 carrying out in communication beginning or communication period.
For the call setup of visual telephone, send the calling that travelling carriage is set up radio bearer (bearer), the calling of setting up 3G-324M then.The W-CDMA system uses unristricted digital information (UDI) (a kind of transparent connection type) as circuit data.For visual telephone, (quarter common intermediate format QCIF) in (176 * 144) is the 64kbps of symmetry to the transmission/receiving velocity of circuit data at 1/4th common intermediate formats.In other words, per second transmits 10 frames.
In order to set up the 3G-324M visual telephone, in UMTS, set up video bearer as the 64kbps circuit data, then based on H.245 equity (peer-to-peer) negotiation (negotiate) control information.In order to join, in the circuit commutative field of core net, handle calling based on the No.7 signaling with PSTN.
For the video alerting service is provided, video alerting server 17 can join with the traditional MSC 13 based on No.7 or BICC.BICC is the signaling protocol between the soft switch, and sends the beared information with various multi-medium datas efficiently.
HLR 14 is databases of storing subscriber information, and itself and MSC 13 join, and storage is about user's information whether the book videos ring is served.If the user has subscribed the video alerting service, then MSC sends to video alerting server 17 with calling.In receiving mobile 18, open the session of 3G-324M, set up calling to receiving MSC from sending MSC.
For the video alerting service is provided, sends MSC and be established to video alerting server 17, arrive the calling 3G-324M of transmission travelling carriage then.Video alerting server 17 comprises the information about the travelling carriage that can support 3G-324M.
Usually, setting up end-to-end visual telephone will take a long time.Yet in the present invention, the MSC of core net handles calling, and this has reduced the time of call setup.In this case, do not need to change travelling carriage, on the contrary, the call setup unit is changed into from video alerting server 17 and is sent travelling carriage 11.For high speed inserts, when setting up calling, video alerting server 17 uses the capability negotiation of handling in the predetermined values conduct H.245 (capability negotiation).
In the present invention, use two kinds of multi-media processing methods.
At first, in order to join with 3G-324M, the multi-medium data of user storage is divided into video flowing and speech stream is stored in the video alerting server 17, is sent to then to send travelling carriage 11.
Then, multi-medium data, and is sent to and sends travelling carriage 11 in video alerting server 17 with stored in file format.
The multi-medium data that is stored in the video alerting server 17 comprises file header, video flowing and speech stream.File header comprises about Video Codec (as H.263), voice codec (as AMR), multi-medium data length, video image resolution (as QCIF), speech coding sample rate (as 63kbps) and the information on the first storage date.
The advantage of using data structure shown in Figure 4 to have is can deal with data and needn't travelling carriage be changed, but its shortcoming is, can not exchange multi-medium data in video alerting server 17.In other words, when the content of multimedia in editor or the transmission internet, should use predetermined instrument rather than general authoring tool.
On the contrary, use internet or international document form to allow easily to authorize and send content of multimedia.Yet, do not call out because the content of multimedia with this document form is not normal 3G-324M, so travelling carriage should have software module and converts the content of multimedia with this document form to normal 3G-324M and call out.In addition, H.245 signaling protocol can be discerned the content of multimedia that file format and broadcast have this document form, and this can easily realize by revising parameter.
Defined file format and can be exchanged with the 3GPP standard as shown in Figure 5 among the present invention.
Can use the MP4 file format and the 3GP file format that define in the stream of packets service (PSS) of 3GPP.If use 3GP, because 3GP can exchange with the VOD file format, therefore content of edit easily.
For the 3G-324M with 3GPP definition joins, can to multimedia use by the packet network definition H.323, by the SIP mediaphone of the 3GCF of 3GPP2 definition and 3GPP, H.263 and G.723.1, and can use the MP4 file format.
Fig. 6 is the flow chart of describing according to the video alerting method of the embodiment of the invention.
As shown in the figure, before opening the video-phone session that sends between travelling carriage 11 and the receiving mobile 18, the multimedia messages that receiving mobile (callee) defines is sent to the transmission travelling carriage based on the 3G-324M standard.
If the callee wishes during ring up video to be sent to the screen of calling transmission travelling carriage 11, then the callee can set up to wish to send to and call out the video that sends travelling carriage 11, perhaps by using calling receiving mobile 18 or user terminal 19 to upgrade the video of setting up in advance via internet or asynchronous wireless telecom-munication accessing video ringing server 17.Comprise many methods of using Web server 21, WAP server 22 and ARS 23 by access to the Internet.
For the video alerting service is provided, hope sends to the call server of calling out transmission travelling carriage 11 with video and uses calling receiving mobile 18 or user terminal 19 by asynchronous wireless telecom-munication or access to the Internet video alerting server 17 during ring up, and foundation expectation in advance sends to the video that calling sends travelling carriage 11.Obviously, use the access to the Internet method of Web server 21, WAP server 22 and ARS23 to have a variety of.
Subsequently, at step S601 and S602, call out and send travelling carriage 11 to calling out receiving mobile 18 transmission callings.At step S603, MSC is to the positional information of HLR inquiring user and whether subscribed any value-added service.
At step S604, MSC recognizes that the callee has registered the video alerting service, and at step S605, the 3G-324M that is set to video alerting server 17 calls out, and is assigned to the data channel of the 3G-324M calling of travelling carriage 11.
If set up the 3G-324M video phone call between video alerting server 17 and travelling carriage, and distributed the data channel of 3G-324M video phone call, then in step 607, video alerting server 17 sends predetermined video to travelling carriage 11.At step S608, the MS decoded video produces the video data of recovery and show video data stored on display unit.
At step S609, send MSC and be established to the video phone call that receives MSC, at step S610, receive the MSC request and receive the data channel that MS distributes the 3G-324M video phone call.If form the session of video phone call,, discharge the 3G-324M video phone call that sends between MSC and the video alerting server 17 then at step S611.Because process afterwards is identical with the proper communication call treatment of 3G-324M video phone call, therefore be not described further here.
If the callee has the voice data of setting up in advance (as music) in advance, then can during ring up, voice data together be sent together with video.That is, can provide video alerting service and voice frequency ringing service simultaneously.
If there is not preliminary election to set up chime, then only calling out display video on the screen that sends travelling carriage 11, perhaps calling transmission travelling carriage 11 can be accompanied by the video oneself that is sent provides basic music.When beginning to communicate by letter, can when beginning, communication disappear automatically at the video that shows on the screen of calling out transmission travelling carriage 11, perhaps can be shown to sign off always.In addition, the video that sends during ring up can be stored in to be called out in the memory that sends travelling carriage 11, thereby can show it once more or send to other travelling carriages at any time.
Fig. 7 is a flow chart of describing video alerting method.Content providing server 20 makes the callee pass through Web server 21, WAP server 22 and ARS 23 accessing video ringing server 17.Then, allow the callee select when the callee receives call, calling out the video content that shows on the screen that sends travelling carriage 11.Selected video can upgrade afterwards.
