Object register machine 2013: be connected to above-mentioned management of process device 2011, in two professional stack telegons the object register machine provide upper layer application and with the management of the adaptive instance objects of following layer interface, these objects comprise H.323 object, session object, WEB session object and upper layer application.
State supervisor 2014: also be connected to above-mentioned management of process device 2011, system, business and state of resources in management and the control video signal value-added service terminal, comprising the management of call state H.323 20141, realize in the terminal system the H.323 states such as state registration, calling and media delivery of professional stack; Service resources condition managing 20142 is responsible for the management of critical resource in H.323 professional stack and the WEB service stack and the condition managing 20143 of system resource.
From figure, it can also be seen that, the left side public H.323API301 and look the interface adaptation layer of audio A PI302 corresponding to videoconferencing service among Fig. 2, socket API303 is corresponding to the interface adaptation layer of WEB service among Fig. 2.Top media player 101, web browser 102 and other separate customer ends 10N are corresponding to the application layer among Fig. 2.Therefore, management of process device 2011 is connecting interface adaptation layer and application layer, and connecting event handler 2012, state supervisor 2014 and object register machine 2013, play for the effect that journey coordinates of advancing of fitting between top application layer and the two professional stack by event handler 2012, state supervisor 2014 and object register machine 2013.
Fig. 4 is from the hierarchical diagram of Fig. 2 and in conjunction with the structural representation of the abstract system of the present invention of coming out of Fig. 3.The left side of Fig. 4 is that H.323 videoconferencing service imports some APP2 and WEB service importing point, be connected respectively to the two professional stack telegon 201 that includes management of process device 2011 and the data processor 2012 that links to each other with management of process device 2011, object register machine 2013 and state supervisor 2014, management of process device 2011 is connected to H.323 channel and WEB channel by H.323 videoconferencing service stack 3001 and WEB service stack 3002 respectively, thereby carries out videoconferencing service and Internet service respectively.In conjunction with Fig. 5
Flow chart the present invention may be better understood is how to utilize this structure to enable H.323 videoconferencing service and Internet service simultaneously and realize two kinds of conversions between the business by object and incident.
There are two class guiding service modes for video signal value-added service itself, a kind of guiding service mode based on number, another is based on the professional lead-in mode of WEB, and two professional stack video signal value-added service terminals need be supported this dual mode.This patent is a core with two professional stack telegons, realizes different entities object and incident reciprocal process in the following pair service terminal of different business lead-in mode.Operation principle with the two professional stack telegons of following two embodiment process descriptions.
Embodiment 1: based on the guiding service mode of number
S1: system initialization, suppose that the two professional stacks of utilization of the present invention support that H.323 the system of videoconferencing service and WEB type business supports the radio phone terminal of video signal value-added service.Be responsible for terminal address, terminal alias and number are registered to the gatekeeper system together by two professional stack telegons, and obtain H.323 agreement token (H.323 TOKEN) of terminal, as among Fig. 5 from management of process device 2011 to shown in the arrow of videoconferencing service stack 3001 H.323;
S2: after the terminal initialization, the user begins to visit certain video signal value-added service (being WEB type business) by dialing certain special service number (as 16800008), being that the number mode is professional imports, we think this moment incident has taken place: promptly the user dials and cries, so with event registration in event handler 2012, be EventGenerationList=(DIAL), and register and order list of thing EventSubscriptionList=(CALLANSWERED), the meaning that list of thing is ordered in registration is to order a call answering incident; And registry object, the sign that the object that relates at this moment has application identities ID, distribute to session is session identification ID, H.323 identify ID is the special service number 16800008 that the user dials.That is to say that two professional stack telegons are registered the object information ApplicationID=DIAL of this application in object register machine 2013; SessionID=x; H323ID=16800008; And the H.323 call state H323=Dialing in the update mode management 2014, carry out professional route by general H.323 videoconferencing service stack 3011, set up H.323 session, shown in last process of the S2 step of Fig. 5 arrow from the management of process device to professional stack H.323.
S3: application server carries out business authentication, return authorized user message, and the entry point information URL of application access, that is to say, incident has taken place---call answering, incident CALLANSWERED activates the event notice 20123 in the task manager, this event registration in task manager, i.e. registered events sequential list EventGenerationList=(DIAL; CALLANSWERED), the incident of ordering of this moment is on-hook, therefore registers EventSubscriptionList=HANGUP; Two professional stack telegons upgrade the object information of this application, application ID or the DIAL of this moment, session id or x, H323ID still is 16800008, many entry point information URL to the Internet suppose that this entrance uniform resource locator is that URL is chatroom:TOKEN=0xaaaaaa.That is APPlicationID=DIAL:SessionID=x:H323ID=16800008:URL=http: //chatroom:TOKEN=0xaaaaaa.
S4: management of process device 2011 returns to the WEB browser application that WEB service imports some APP1 with incident and entry point information (URL), shown in the arrow S4 of Fig. 5.
S5: web browser is taken over the guiding service process, is directed to the management of process device, is carried out processes such as event registration and renewal, object registration and renewal again by the management of process device, and carries out WEB service by the WEB service stack.But because carry out WEB type service such as information retrieval this moment, two professional stack telegons are carried out professional route by the WEB service stack, for the two professional stack telegons of stateless business procedure trigger event not, but need to upgrade the URL object information.
S6: when the user triggers H.323 session action in the WEB service process, H323 for example: //MCU, two service interworking devices are intercepted and captured H323 and are called out, and upgating object information and list of thing (suppose that here H323 supports a plurality ofly to call out simultaneously, promptly call out nested), carry out business procedure by professional stack H.323.
After the S7:H.323 session stop, H.323 professional stack sends abort message to the management of process device, break event has taken place this moment, the management of process device is registered this break event and related object in event handler and object register machine, the notice WEB service imports the some WEB service and recovers, and carries out WEB service by WEB service stack 3002.
By continuous foundation to incident related in the top process, and in incident release later, carried out the continuous cut-out between videoconferencing service and the WEB service, return to idle condition (IDLE) up to all list of things of event handler and the list object of object register machine, and discharge all object instances, process of the present invention just can stop.
Embodiment 2: based on the guiding service mode of number
At first, the terminal system initialization is responsible for terminal address, terminal alias and number are registered to the GK system together by two professional stack telegons, and obtains H.323 agreement token (H.323 TOKEN) of terminal, with the S1 step among the embodiment.
Then, the user inserts video signal value-added service portal website by one-touch mode, activate web browser, two professional stack telegons are registered this access events in task manager 2011, in object register machine 2013, register the object information ApplicationID=BROWSER (in embodiment 1 user to dial and use ID under the situation of special clothes phone be the application identities of calls customer terminal, situation about inserting at WEB is next to be browser) of this application; SessionID=x; URL=http: //default-Portal, carry out the follow-up business process by the WEB service stack, this process is similar to the S5 step among the embodiment 1.
For stateless information retrieval business, trigger event not in two professional stack telegons upgrades URL but need to carry out object information in the WEB service process.
When the user triggers H.323 session action in the WEB service process, H323 for example: //MCU, two service interworking devices are intercepted and captured H323 and are called out, list of thing in object information in the upgating object register machine 2013 and the event handler 2012, the incident of this moment is that the user triggers H.323 session, the object ApplicationID of this moment still is BROWSER, and SessionID is x, the new H.323 number of terminal that H.323ID will call out for the user.It is equivalent to the S6 step among the embodiment 1.
Process is carried out successively then, returns to idle condition (IDLE) up to all object list of things, and discharges all object instances.
Preferably, the list of thing in the event handler of the present invention is index with the object.
