Below specifically in conjunction with the accompanying drawings, describe the method and system framework of between a plurality of video monitoring platforms, realizing business intercommunication according to of the present invention in detail.
Video monitoring platform business intercommunication system architecture
Fig. 1 has schematically shown the system architecture that realizes business intercommunication according to of the present invention between a plurality of video monitoring platforms.Be used between a plurality of video monitoring platforms, realizing that the video monitoring platform business intercommunication system architecture of business intercommunication comprises: gateway monitoring administration platform GKM101, the common customer end unit PB_CU103 that links to each other with gateway monitoring administration platform GKM 101, the a plurality of video monitoring platforms (or system) 105 that are connected with described gateway monitoring administration platform GKM 101,107...., wherein each video monitoring platform further comprises internal core processing platform CPS, for example CPS1051 or CPS1071, and with the corresponding signaling interface IF and the media gateway MGW of described gateway monitoring administration platform GKM 101 interfaces.Wherein gateway monitoring administration platform GKM 101 and common customer end unit PB_CU103 are the cores according to the system architecture of video monitoring platform interworking service of the present invention.
The function of the gateway monitoring administration platform GKM 101 that increases newly according to the present invention mainly is: the Signalling exchange between each video monitoring platform of unified management and the input and output of video flowing, and all interworking services are managed, authenticate and charge, and preserve the data of all interworking services.In the video monitoring system of prior art, usually be that unit divides (for example monitor supervision platform 105,107) with the monitor supervision platform, operation flow in the video monitoring system is handled in internal system central processing platform (CPS, Center process system) (for example CPS 1051,1071).According to the present invention, the interworking service between each monitor supervision platform is by gateway monitoring administration platform GKM 101 management.Gateway monitoring administration platform GKM 101 needs to carry out information interaction with monitor supervision platform periodically, the data of sync correlation, and it is inconsistent to avoid occurring the record of same information on GKM101 and monitor supervision platform, influences the carrying out of interworking service.
In the prior art, because each video monitoring platform all is the platform that has self contained data base and have the system of improving, therefore, each video monitoring platform can't be discerned the client of external system; On the other hand, if the client of external system need visit a video monitoring platform and wishing when obtaining the video monitoring resource that this video monitoring platform provides, the client of this external system also need login with the client of this video monitoring platform self, and this has caused many inconvenience.For addressing the above problem, the method that the present invention adopts the user to shine upon, realize of the visit of monitor supervision platform external user to monitor supervision platform, that is to say that same client has different user account numbers on different monitor supervision platforms, on GKM, realize the mapping of user account number, obtain the user account number of client on monitor supervision platform and login each monitor supervision platform, this process is finished automatically by system, to user transparent.In the present invention, interworking service is based on that user mapping provides, and the core of gateway monitoring administration platform GKM is the management to user's mapping.User's mapping refers to a client and has a plurality of user account numbers, corresponds respectively to different video monitoring platforms, and promptly this client has the inside account number of this video monitoring platform at its each video monitoring platform that is authorized to visit.According to the present invention, when the different video monitoring platform of client access (as monitor supervision platform 105), automatically client's user account number is mapped to the user account number that the user has at monitor supervision platform 105 by the GKM system among the present invention, with this user account number accessing video monitor supervision platform 105.For this reason, gateway monitoring administration platform GKM101 has preserved all interworking service clients' user's mapping (enum) data and authority (authority refers to the control point resource that the client has).
Gateway monitoring administration platform GKM 101 and common customer end unit PB_CU 103 for example form the C/S system.Wherein, gateway monitoring administration platform GKM 101 for example can be server S erver, and common customer end unit PB_CU 103 can be client computer Client.Preferably, common customer end unit PB_CU 103 is clients of using to the client who needs a plurality of video monitoring platforms of frequent access, the direct logging in gateway monitoring administration of this client platform GKM 101, directly manage by gateway monitoring administration platform GKM 101, that is to say the client software that provincial common customer is used.Use the client of common customer end can be called common customer, its service fulfillment is is directly accepted at gateway monitoring administration platform GKM, use common customer end login GKM, finish the AAA checking, can directly visit each monitor supervision platform to obtain the monitoring resource by the common customer end at GKM.Common customer uses special common customer end unit PB_CU to login.Be to use common customer end unit PB_CU 103 logging in gateway monitoring administration platform GKM101 though should be understood that common customer, still each video monitoring platform (for example monitor supervision platform among the figure 105,107) of video source really is provided.101 login, authentication and management that provide the client of gateway monitoring administration platform GKM are authorized and function such as charging, and gateway monitoring administration platform GKM 101 itself do not have any video resource, and video resource is provided by each video monitoring platform.
The user is by common customer end unit PB_CU 103 logging in gateway monitoring administration platform GKM101, and by after the checking, and the direct monitor supervision platform of access authorization is just asked the video monitoring resource of mandate.Communicate by letter measured SIP, the rtcp protocol of gateway monitoring administration platform GKM 101 and common customer end unit PB_CU 103.But, the structure and the employed agreement of each video monitoring platform (for example the video monitoring platform among the figure 105,107) are widely different at present, and what most of video monitoring platform used is proprietary protocol, and therefore each video monitoring platform of the prior art can't communicate with video monitoring interworking service system architecture according to the present invention.
In order to realize interworking service, according to the present invention, the correspondence with foreign country of each monitor supervision platform uses signaling interface IF, and the effect of signaling interface IP is that the privately owned signaling that use the inside of video monitoring platform is converted to communication signaling based on the standard Session Initiation Protocol, realizes communicating by letter of monitor supervision platform and outside.The mapping of interior external signalling comprises the conversion (only host-host protocol changed, the explanation of PTZ order at CU finish) of client to front-end camera control signaling, and the signaling of conversation procedure etc. are finished the signaling of external perimysium reference and the mapping of monitor supervision platform interior signaling.Management information synchronously, comprise the registration of monitor supervision platform, checking, heartbeat detection, subscriber data, information such as resource information, the charging factor synchronously.
In addition, also be in order to realize interworking service, also provide external video flowing interface at each monitor supervision platform, be responsible for the transmission of video flowing between inside and the outside, the inner privately owned video flowing transport protocol conversion of using of video monitoring platform is become the video flowing host-host protocol (RTP/RTSP) (Real-time Transport Protocol/Real Time StreamingProtocol, RTP/real-time streaming protocol) of standard.The video flowing interface that is provided comprises inner MGW and outside MGW: outside MGW, the media gateway that monitor supervision platform external video stream input monitoring platform is used.Inner MGW, the media gateway of the outside usefulness of monitor supervision platform interior video stream output monitoring platform.MGW is divided into inner MGW and outside MGW in principle, and inner MGW realizes the output (CU) of video monitoring platform video flowing; Outside MGW realizes the access (PU) of external video stream; Also can be merged into a MGW to the function of inner MGW and outside MGW, realize the access of external video stream and the output of interior video stream simultaneously, like this, MGW is CU for monitor supervision platform, also is PU.By provide MGW on each video monitoring platform, gateway monitoring administration platform GKM101, common customer end unit PB_CU 103 just can communicate with each video monitoring platform (for example video monitoring platform 105,107).
Preferably, be based upon on the TCP/IP network in the system architecture that realizes business intercommunication between a plurality of video monitoring platforms according to of the present invention, therefore, as long as network can reach and can realize the present invention.
Preferably, the method and system framework of business intercommunication of realizing between a plurality of video monitoring platforms according to the present invention is mapped as the basis realization with the user.In the video monitoring system in the prior art, owing to do not carry out user's unified management, each video monitoring platform can only be discerned the user of self, can not discern the user of other video monitoring platforms.Therefore, when hope realizes business intercommunication, when the user of non-video monitor supervision platform logins this video monitoring platform, preferably, after finishing user's mapping, the user account number that client's user account number converts video monitoring platform inside to signs in to described video monitoring platform, obtains the video monitoring resource that video monitoring platform provides.Below describe in detail is to be mapped as the basis with the user to realize the technology contents of realizing the method and system framework of business intercommunication between a plurality of video monitoring platforms of the present invention.
Video monitoring platform business intercommunication type
The type of service of video monitoring platform intercommunication has four kinds: public domain P type client (Public User) (or claiming common customer), monitor supervision platform I type client (Input User), monitor supervision platform O type client (Output User), and monitor supervision platform I/O type client (Input/Output User).
For the newly-increased client who needs frequent access different video monitoring platform (supposing monitor supervision platform 105,107 here), for convenient management and raising access efficiency, newly open P client's business, P client uses common customer end unit PB_CU103 as client, behind the logging in gateway monitoring administration platform GKM 101, can visit a plurality of different video monitoring platforms simultaneously.For example, when accessing video monitor supervision platform 105, common customer end unit PB_CU 103 uses user's mapping (O client) of monitor supervision platform 105 to login video monitoring platform 105 automatically; When accessing video monitor supervision platform 107, common customer end unit PB_CU 103 uses user's mapping (O client) of monitor supervision platform 107 to login monitor supervision platform 107 automatically.So P client's correspondence the O client of video monitoring platform.
For video monitoring platform (as video monitoring platform 105,107) original client, increase the demand of other video monitoring platform monitoring resources of visit as needs, then need to gateway monitoring administration platform GKM 101 registrations and application interworking service, gateway monitoring administration platform GKM 101 shines upon and granted rights for these users provide at the user of other video monitoring platforms.The original client of this type of video monitoring platform (being assumed to be monitor supervision platform 105) promptly needs from the client of other video monitoring platform input (Input) video resources if needing the client of other monitor supervision platform monitoring resource requirements of monitoring is exactly I client.And other video monitoring platforms that I client need visit (being assumed to be monitor supervision platform 107 here), user's mapping need be provided, this user's mapping only can be to system's outside output (Output) video resource, so become O client, the I client of monitor supervision platform 105 is when access monitoring platform 107, need the O client who converts video monitoring platform 107 through GKM to login video monitoring platform 107 then, obtain the video monitoring resource.So I client's correspondence the O client of outer video monitoring platform.
Client for having had a plurality of video monitoring platforms (hypothesis has video monitoring platform 105,107) access rights here needs to use a plurality of client softwares and a plurality of user account number at present.Login is during video monitoring platform 105, needs to use the client software of video monitoring platform 105, with the user account number login of video monitoring platform 105; Login is during video monitoring platform 107, needs to use the client software of video monitoring platform 105, with the user account number login of video monitoring platform 105.In the present invention, for this client, newly-increased a kind of I/O client's business, no matter I/O client is having any video monitoring platform login of authority, as client software login video monitoring platform 105 with video monitoring platform 105, or with the client software of video monitoring platform 107 login video monitoring platform 107, all control point resources that can access customer have authority, this type of client not only needs input (Input) video resource but also need output (Output) video resource, so become I/O client.Because the video monitoring platform of each login may be different,, make things convenient for client's application so same client need force unification at I/O client's user account number of different video monitoring platform.So I/O client's correspondence the I/O client of outer video monitoring platform.
Exist corresponding relation between four kinds of clients, as: each P client is corresponding O client in the video monitoring platform inside of being visited; The I client of video monitoring platform (or system) i is the corresponding O client of video monitoring platform (or system) j of visit; The I/O client of corresponding video monitoring platform (or system) i of an I/O client of video monitoring platform (or system) i.
● public domain P type client
Common customer needs a plurality of video monitoring platforms of frequent access, levels of clients---and provincial, belong to the direct customer of GKM, do not belong to any video monitoring platform.
P client directly logins GKM with common customer end unit PB_CU.
● monitor supervision platform I type client
The client of monitor supervision platform needs other video monitoring platforms of visit to monitor the client of resources, levels of clients---region.
I client logins monitor supervision platform with the CU of video monitoring platform.
● monitor supervision platform O type client
User's mapping of the external client of monitor supervision platform is the virtual client of video monitoring platform, for the external client access of video monitoring platform (the I clients of P client or other video monitoring platforms).
O client can not directly login video monitoring platform, only shines upon the login video monitoring platform by the user.
● monitor supervision platform I/O type client
The client of monitor supervision platform, the monitoring resource of other monitor supervision platforms of needs visit also provides other monitor supervision platform access monitoring platform internal control resources, levels of clients---stride region.
I/O client can also can login at monitor supervision platform (or system) j in monitor supervision platform (or system) i login, and corresponding I/O client's login username, password need be forced unified.
Annotate: suppose that here monitor supervision platform (or system) i and monitor supervision platform (or system) j are the intercommunication platforms, corresponding I/O client.
Video monitoring platform business intercommunication flow process
● P client's business intercommunication flow process
Accompanying drawing 2 has been described the flow chart of realizing P client's business intercommunication in video monitoring platform according to the present invention.
1) certain Public User (PB_U1) login GKM, the concurrent family information request checking of seing a visitor out, ([PB_UserID] [PB_Ui_Passwd]).
