Fig. 5 illustration according to the embodiment of the invention based on the conference system of SIP with based on the intercommunication flow graph between the supervisory control system of SIP, comprised foundation, end and the control of cloud mirror of video session.Below for concise and to the point purpose, mainly based on the video conferencing system of SIP and video monitoring system as shown in Figure 2 to be the operation principle that example has been described according to the fusion of the embodiment of the invention video system of video conferencing system and video monitoring system.
In fact, video conferencing system at first should obtain the control point tabulation of video monitoring system, and this can perhaps realize by the IWG inquiry by being configured in conference system.This inquiry is based on Web service (Web Service).
For the purpose of example, the key parameter in the control point tabulation is as follows:
It will be appreciated by those skilled in the art that, in control point tabulation, can comprise channel number, control point title, whether allow the control of cloud mirror such as above-mentioned front end numbering, control point, parameter such as online whether, but be not limited to these parameters, and the form of the parameter in the control point tabulation also is not limited to above-mentioned performance, and for example the front end numbering can be title or other.
With reference to figure 5, in step 501, conference system 32 sends INVITE to Interworking gateway IWG31, comprises the numbering of the control point that will visit among the request address Request-URI of this message, and in SDP, comprise the media formats that conference system is supported, the receiver address information of medium.For the purpose of example, as follows:
Therefore, conference system 32 can be judged monitor supervision platform under the control point according to the information of request address, and sends the IWG of call request to correspondence.For example, in illustrative INVITE, the domain name of the host machine part indication supervisory control system among the request address 00000001_01@video_surveillance1.com, and User Part can to indicate the front monitoring front-end under this control point be 00000001_01, wherein 00000001 expression front monitoring front-end is numbered, and 01 is the channel number of this control point correspondence.
And IWG 31 is as B2BUA, after receiving this INVITE, this message is met the modification of supervisory control system, for example remove SIP expansion for supporting that convention business is done, perhaps provide by front monitoring front-end owing to the general SDP of supervisory control system (Late SDP), can not comprise SDP in its INVITE, and send INVITE to supervisory control system 38.
In step 503, supervisory control system is returned 200OK message, and the SDP that comprises front monitoring front-end in this 200OK message provides (SDP Offer), carries information such as media formats that this front monitoring front-end uses, medium receiver address in this SDP provides.
And IWG 31 receives this 200OK message, can make amendment to it, for example checks the common media formats of supporting of both sides, if having, the media formats of then selecting both sides all to support, and the medium forwarding address of definite IWG send 200OK message to conference system 32.If no, then IWG 31 need do the conversion of coded format.
So in step 505, conference system returns ACK, IWG sends ACK to supervisory control system, comprises the SDP that SDP Offer is replied in this ACK message and replys (SDP Answer).
So far, conference system and surveillance are successfully set up session.So in step 507, IWG 31 sends to conference system based on Real-time Transport Protocol with the video in the supervisory control system, thus the video of the user capture arrival self-monitoring system in the conference system.In this step, if both sides do not have the common video code model of supporting, then IWG 31 will carry out code conversion.Video coding adopt standard MPEG-4, H.264 wait, the groundwork of code conversion is the decoding video stream that will receive, and then is encoded into the video format that goal systems is supported, such as from H.264 converting MPEG-4 to, coded format does not repeat them here referring to the associated video coding criterion.
In the video access process or before, conference system 32 can carry out PTZ control to camera, shown in step 509, can adopt the INFO carrying PTZ control information among the SIP, also can adopt the dual tone multi-frequency dtmf signal among the RFC2833.IWG 31 can be converted into the PTZ control command of using in the supervisory control system 38.
Key parameter example in the PTZ control messages is as follows:
PuId=00000001; / front monitoring front-end numbering
ChannelNo=01; For example there are 16 road cameras in the channel number of the correspondence of/control point at this supervision front end, and it is the 1 the tunnel
OpCode=turn up; / command code, operation such as comprise upper and lower, left and right, amplify, dwindle
OpParameter=1; / command code corresponding parameters is such as speed.
Next, in step 511, supervisory control system 38 is responded 200OK message by 31 pairs of these INFO of IWG.
In the time will finishing accessing video, in step 513, conference system 32 sends BYE to IWG 31, and IWG 31 sends BYE to supervisory control system.
At last, in step 515, IWG 31 stops transmitting video flowing after receiving 200 OK of supervisory control system 38, and sends 200OK to conference system 32.
It will be understood by those skilled in the art that the forwarding step that can also comprise Temporary Response message (for example 180Ringing, 183 etc.) in this flow process before step 503, the Temporary Response message that IWG 31 transfer supervisory control systems are returned is given conference system.
In an embodiment of the present invention, adopted some normal process of SIP, Session Initiation Protocol is adopted in for example foundation of session, termination, and the SDP agreement is adopted in the description of medium, relates to Media Stream and then adopts the RTP/RTCP agreement.
Certainly, those skilled in the art will appreciate that being not limited to above-mentioned conference system and supervisory control system based on SIP carries out session, the conference system of other type and supervisory control system also can be carried out session by network element IWG.
Fig. 6 illustration carry out the flow chart of session according to an embodiment of the invention by IWG and supervisory control system based on conference system H.323.Similar to the above, conference system at first obtains the tabulation of the control point that can visit.In the present embodiment, will not give unnecessary details with above-mentioned principle similar operation or process at this.
As shown in Figure 6, set up in the process 610 in session, conference system 36 sends setup message to IWG 31, and IWG 31 returns call proceeding message and represents to handle this message.
So IWG 31 sends the gatekeeper of license request ARQ to the conference system place, whether this gatekeeper's decision-making allows this calling, is then to return permission to confirm ACF, otherwise returns permission refusal ARJ.
After receiving ACF, IWG 31 sends INVITE to supervisory control system 38, specifies the video of control point in the request setup message.
Supervisory control system is returned 200OK, comprises information such as media formats that supervisory control system uses, medium receiver address among this 200OK.Similarly, supervisory control system also can send Temporary Response 180Ringing, so IWG 31 returns alerting message to conference system.After receiving 200OK, IWG 31 sends connect message to conference system.
According to the H.323 requirement of agreement, between conference system and IWG, carry out capability negotiation (TCS) and principal and subordinate decision (MSD).
Open logic channel according to flow process H.323, if there is not common capability set between conference system and the supervisory control system, then IWG need carry out code conversion.
After logic channel was opened successfully, IWG 31 sent ACK to supervisory control system, comprises the SDP Answer that replys in this ACK message.So far, conference system and supervisory control system are successfully set up session.
In step 620, the video in the supervisory control system is sent to conference system according to the RTP/RTCP agreement, thereby can have access to video in the supervisory control system.
In the video access process or before (after setting up session), step 630 for example, conference system can carry out PTZ control to the camera in the supervisory control system, can adopt H.281 agreement.And IWG can convert thereof into the PTZ control command of using in the supervisory control system
In step 640, in the time of finishing accessing video, conference system sends release complete message to IWG 31, and IWG 31 sends and breaks away from request DRQ to the gatekeeper in the conference system, and IWG sends BYE to supervisory control system simultaneously.
After receiving the 200OK of supervisory control system, IWG 31 stops transmitting video flowing.
