Embodiment

Core concept of the present invention is: the IT network user passes through the conference management client and the MPTY conferencing information is set and initiates the MPTY meeting to conference management server, conference management server sends to AS via Web Portal after the MPTY conferencing information that receives is converted to the establishment conference request; AS carries out authentication according to creating the information of carrying in the conference request to the host who initiates the MPTY meeting, and calls out the host by SoftSwitch, and AS applies for meeting-place in many ways to MRS simultaneously, and the host is added the meeting-place in many ways of having applied for; AS calls out the participant according to creating the information of carrying in the conference request by SoftSwitch, and AS applies for the participant of access success is added described meeting-place in many ways of having applied for to MRS simultaneously.The inventive method realized that user in the IT network initiates and communication network users between media conference in many ways.The inventive method has realized that by NGN the IT network user creates and managerial meeting in real time by open interface.

For making purpose of the present invention, technical scheme and advantage clearer, below with reference to the accompanying drawing preferred embodiment that develops simultaneously, the present invention is described in more detail.

Fig. 1 is that the present invention passes through the networking structure schematic diagram that NGN realizes the MPTY meeting, from Fig. 1 as seen, realizes the MPTY meeting in order to pass through NGN, comprises in the networking with lower unit:

The conference management client: being used to install the conference management client software, is the terminal that conference management client software interface is provided to the user.The open TCP/IP port of conference management client, the information interaction between realization and conference management server.The conference management client receives the conference management solicited message of user by the input of conference management client software interface, and this information is sent to conference management server; Simultaneously, the conference management client receives the message that client management server returns or initiatively report, and the conference status in the message is presented on the user interface.Wherein, the conference management client software can exist with the form of stand alone software program, also can be the plug-in unit of Web browser; The conference management solicited message comprises the request for conference information of creating, closing session solicited message, adds participant's solicited message and deletion participant solicited message etc.

Usually, the conference management client can be separately a personal computer (PC), also can use a PC jointly with conference management server, only needs the conference management client provide the interface protocol of Web Portal opening to get final product.The conference management client software can also be integrated with NGN audio/video software terminal.

Conference management server: receive the conference management request of conference management client, the conference management solicited message of agreement between conference management client and conference management server will be satisfied, be converted to satisfy between conference management server and the Web Portal and send to Web Portal behind the conference management request message based on http protocol, and give the conference management client the forwards that Web Portal returns.The agreement of carrying conference management request and response message does not limit between conference management server and the meeting administrative client.A conference management server can be connected with a plurality of conference management clients, and different conference management clients can be distinguished with different IP addresses.

To the portal server of Internet or other IT network opening, generally be connected with Internet or other IT network among the Web Portal:NGN by fire compartment wall.The conference management request message that Web Portal is used for receiving from conference management server is transmitted to AS.The open serve port that meets http protocol of Web Portal is realized MPTY meeting interface.The fail safe that conference management server inserts Web Portal can realize by login authentication, conversation mechanism and the Secure Sockets Layer(SSL) technology based on HTTP.

AS: resolve conference management request message from Web Portal, realize service logics such as Multi-Way Calling control, charging, media stream resources such as control MRS foundation/deletion meeting-place, broadcast voice, video, the call event that monitoring soft switch (SoftSwitch) reports etc.

MRS: under the control of AS, create the meeting-place and insert each side's terminal, and the each side in the meeting-place plays Media Streams such as voice, video.Reception is play to the participant who inserts the meeting-place of appointment from the Media Stream of each side in the meeting-place again.MRS externally provides SIP signaling interface and real-time transport protocol (rtp)/RTCP Real-time Transport Control Protocol (RTCP) MCI that meets Session Initiation Protocol.

SoftSwitch: by media gateway, SGW and PSTN net, mobile network, the Internet net interconnecting of IP bearer network, realize comprising pstn telephone terminal, portable terminal, the PC software terminal that is connected with NGN IP bearer network, soft switch intelligent terminal (intelligent terminal) etc. calling access, route, continue, control etc.

Based on networking structure shown in Figure 1, the present invention proposes the method that a kind of NGN of passing through realizes the MPTY meeting, Fig. 2 is the flow chart that the present invention creates the MPTY meeting, suppose the conference management client software to be installed in the conference management client, the user lands conference management server by the interface that the conference management client software provides, and imported the relevant information of initiating the MPTY meeting, as host's Subscriber Number, the participant's Subscriber Number that participates in a conference, the meeting-place size of initiating meeting, whether start sound-recording function, whether start background music etc.; The conference management client sends to conference management server after can passing through the relevant information packing of serial data packet with the meeting of above-mentioned initiation MPTY; After conference management server receives the relevant information of initiation MPTY meeting of above-mentioned user input, be converted between conference management server and the Web Portal based on the establishment conference request of http protocol, this method is specifically further comprising the steps of:

Step 200～step 201: the establishment conference request after conference management server will be changed is passed through the MPTY meeting interface that NGN provides to the Web Portal to the IT network opening, send to WebPortal, the establishment conference request that while Web Portal will receive is transmitted to AS, AS checks whether the establishment conference request is legal, if it is legal, then return the establishment request for conference success response of carrying session id synchronously to Web Portal, Web Portal is transmitted to the session id that receives the conference management client and shows this information by conference management server simultaneously, enters step 202 afterwards; Otherwise, return process ends after the establishment request for conference success response of carrying error code.

Interface between conference management server and the Web Portal is followed http protocol, and the information parameter of transmission can adopt the carrying of XML formatted file.Specifically, the interface between conference management server and the Web Portal can adopt interface function to represent, function name and input parameter value are transmitted by HTTP request message body, and function return value is realized by the response message body carrying of HTTP request.Creating meeting interface function CreateConf () such as definition is:

String?CreateConf?(String?strCompereID，String[]strCallees，StringstrBackgroundVoice，int?nRecordingType，int?nConfSize)

Wherein, the parameter declaration in the CreateConf () function is as follows:

StrCompereID: the meeting promoter, promptly host's Subscriber Number is defined as character string; Here, Subscriber Number can be the unique identification hosts' such as job number that set in advance in telephone number, the internal network a identification number.Need to prove, if when adopting other identification number outside the telephone number, the mapping table between should pre-configured this identification number in the AS corresponding user's telephone number with this identification number.

StrCallees: invite the participant's who adds the meeting-place Subscriber Number when the host creates meeting, be defined as the character string array.The length of this character string array can be for zero, one or more.

StrBackgroundVoice: whether start when creating the meeting-place and play meeting-place background sound and background sound ID, be defined as character string.Such as: this value is that background sound is not play in 0 expression, be that 1 expression plays with audio file ID is 1 the pairing background sound of audio file, and background sound ID must be consistent with the audio file ID that deposited among the MRS, the background sound that different audio file ID is corresponding different.

NRecordingType: whether start recording when creating the meeting-place, be defined as the integer data.Such as: 0 expression does not start recording; 1 expression starts recording, and the recording file that recording substance can be left in appointment is called in the file of " meeting-place ID_ sequence number .wav ".

NConfSize: the meeting-place size is defined as the integer data, such as being that 0 expression does not need to reserve.AS is according to creating this meeting-place size parameter control participant's number in the conference request and requiring the pre-first to file of MRS meeting-place respective resources.

Need to prove that above-mentioned CreateConf () function can just illustrate according to some parameter of user's needs increase/deletion here, be not used in restriction method of the present invention.

Can adopt remote procedure call or other private message pass through mechanism to carry out information interaction between Web Portal and the AS, specific implementation is a technology as well known to those skilled in the art, can no longer repeat here referring to related protocol.

In this step, AS receives the establishment conference request that Web Portal transmits, check that the parameter of carrying in this message is legal, such as the type that defines in parameter of carrying in this message and above-mentioned the CreateConf () function and range of parameter values legal etc. after, generate and return immediately session id, session id is the integer greater than 0, be used to distinguish the session that different applications are initiated, the session id that each application generates is unique, session id can produce at random, also can produce according to certain method that sets in advance.

After Web Portal receives this session id, set up to create the conference management client and the one-to-one relationship between the session id of session in this locality, such as the corresponding relation between the IP address of the conference management client of session id and establishment session.

After if AS receives and creates conference request, failure is then returned and is created the request for conference failure response for a certain reason, carries the error code that causes failure cause in this response, such as: error code-1 expression system exception; It is illegal that parameter is imported in error code-25 expression into; Error code-26 expression host has created the meeting-place, can not repeat to create etc.

After Web Portal obtains success or failure return value that AS returns, with the result, be session id or failure cause error code, be placed in the HTTP response message body and return to conference management server, conference management server is preserved the corresponding relation of session id and client-requested to set up conversation mechanism, and return information is given client then.

Step 202～step 204:AS is according to creating the information of carrying in the conference request, the host is carried out authentication, and return session initiation to Web Portal and reply, Web Portal replys the session initiation that receives by conference management server and is transmitted to the conference management client and shows this response message simultaneously.

In AS, prestore the IT network user's user profile, whether have host's qualification, residue funds, management participant ability etc. such as this user.After AS receives the establishment conversation request message, whether the user who judges current establishment meeting has host's qualification, if have, then whether this host's residue funds can be finished this Multi-Party Conference, this host and whether have the ability to convene the Multi-Party Conference of creating participant's quantity of carrying in the conversation request message etc., if satisfy above-mentioned condition, then pass through authentication, AS returns session initiation to WebPortal and replys, and Web Portal replys the session initiation that receives by conference management server and is transmitted to the conference management client and shows this information simultaneously; Otherwise failed authentication, AS return the session initiation failure and reply.

Hypothesis session initiation success in this step.

Step 205～step 206:AS sends calling host signaling according to the information of carrying in the establishment conference request to SoftSwitch, and SoftSwitch carries out the calling host after receiving this signaling, and returns the calling host and reply.

Adopt Session Initiation Protocol to realize that specific implementation belongs to technology as well known to those skilled in the art, can no longer repeat referring to related protocol to the control of calling here between AS and the SoftSwitch.

Lets call host success in this step.

Step 207～step 209:AS obtains meeting-place ID and the host is added this meeting-place to MRS application meeting-place, after MRS finishes the meeting-place application and adds the host, meeting-place ID is carried at returns to AS in the successful respond, and between host and MRS, set up the Media Stream passage by SoftSwitch.

Adopt Session Initiation Protocol to realize control between AS and the MRS, specific implementation belongs to technology as well known to those skilled in the art, can no longer repeat here referring to related protocol.

Step 210～step 211:AS returns meeting-place and host's state information to Web Portal, and Web Portal is transmitted to meeting-place and the host's state information that receives the conference management client and shows this information by conference management server simultaneously.

Interface between conference management server and the Web Portal is followed http protocol, and the information parameter of transmission can adopt the carrying of XML formatted file.Specifically, the interface between conference management server and the Web Portal can adopt interface function to represent.

Establishment meeting HTTP interface function CreateConf () is provided in step 200～step 201, here, for the information that will create the request for conference response is returned conference management server from Web Portal, require conference management server to the HTTP interface that Web Portal provides the carrying call back function, ask the call back function NotifyStatus () of executing state to be such as definition:

String?NotifyStatus(String?strSessionID，int?nEventID，String?strConfID，String[]strUserID，String[]strStatus，String[]strDescription)

Wherein, the parameter declaration in the NotifyStatus () function is as follows:

StrSessionID: session id is defined as character string type, in order to discern the corresponding establishment request for conference of successfully having been accepted by AS of this readjustment.

NEventID: asynchronous event ID is defined as integer, is used to distinguish the readjustment message of various objectives, and asynchronous event ID and event description are exemplified below:

1 is illustrated in and creates during meeting replys, and authentication is passed through; 2 are illustrated in and create during meeting replys, and create the success of MRS meeting-place; 3 are illustrated in and create meeting and creating meeting in replying, starting and play background sound; 4 are illustrated in and create during meeting replys, and creating meeting, are starting the meeting-place recording; 5 are illustrated in and create during meeting replys, and the host enters the meeting-place; 6 are illustrated in and create during meeting replys, and call out participant's state; 7 expression request closing sessions are replied; 8 expression hosts add the participant and reply to the meeting-place; 9 expression hosts reply from meeting-place deletion participant; 10 expressions are play the meeting-place background sound and are replied; 11 expressions stop to play the meeting-place background sound and reply; 12 expression beginning meeting-place camed replies; 13 expressions finish meeting-place camed replies or the like.

StrConfID: meeting-place ID, be defined as character string type, when the meeting-place is created successfully, utilize this parameter will return unique identification id that this has created successful meeting-place.

StrUserID: Subscriber Number, be defined as the character string type array, this array is deposited the Subscriber Number that to need in the Multi-Party Conference to participate in returning the each side of talking state, comprises host or each participant's Subscriber Number.Wherein, can be with first value of this array, i.e. strStatus[0] be expressed as the state of host's correspondence.In this step, strStatus[0] be expressed as the result that the host creates meeting.

StrStatus: state value, be defined as the character string type array, at each asynchronous event ID different state values is arranged, be that success, failure, system exception or system are overtime or the like such as the state of certain asynchronous event ID correspondence.

StrDescription: the descriptor of state value correspondence is defined as the character string type array.Such as the reason of the incident failure that is used to specifically describe certain asynchronous event ID correspondence etc.

Need to prove that above-mentioned NotifyStatus () function can just illustrate according to some parameter of user's needs increase/deletion here, be not used in restriction method of the present invention.

Step 212～step 216:AS is according to creating the information of carrying in the conference request, send calling participant signaling to SoftSwitch, SoftSwitch carries out the calling participant after receiving this signaling, and return and call out the participant and reply, during replying, this carries the whether information of access success of participant; Afterwards, AS adds the meeting-place of current meeting-place ID correspondence to MRS application with the participant of access success, after MRS adds the participant, adds between the participant in meeting-place and the MRS by SoftSwitch and to set up the Media Stream passage at each.

Adopt Session Initiation Protocol to realize control between AS and SoftSwitch, the MRS, specific implementation belongs to technology as well known to those skilled in the art, can no longer repeat here referring to related protocol.

Step 217～step 218:AS returns participant's state information to Web Portal, and WebPortal is transmitted to the participant's state information that receives the conference management client and shows this information by conference management server simultaneously.

The specific implementation of this step can adopt the NotifyStatus () function in step 210～step 211 to realize, concrete parameter declaration is seen and no longer repeated here described in step 210～step 211.

So far, the user who initiates to create Multi-Party Conference, be to set up the MPTY meeting-place between host and the participant, each side can carry out Multi-Party Conference by the Media Stream passage of setting up, AS charges to meeting each side according to the charging regulation that has disposed, and the call state of monitoring meeting each side etc., reached the purpose of the present invention by NGN realization Multi-Party Conference.

The method of creating the MPTY meeting from the invention described above as can be seen, pass through interface function between the Web Portal in conference management server and NGN based on http protocol, realized creating the transmission of request for conference and establishment meeting response message, conference management server is transmitted to the conference management client with the conference creation state information that obtains and shows, makes the user who initiates Multi-Party Conference to monitor the process of creating.

When above-mentioned conversation need finish, initiate the request of closing session by the conference management client, Fig. 3 is the flow chart that the present invention discharges the MPTY meeting, conference management server receives the closing session information from the input of conference management client, behind host's Subscriber Number, meeting-place ID etc., be based on the closing session request message of http protocol between conference management server and the Web Portal with the information translation that receives.Web Portal is transmitted to AS with the closing session request message, AS is according to information such as the host's who carries in the closing session request message Subscriber Number, meeting-place ID, verify that the Media Stream passage of initiating the each side of release conference participation after host's identity and meeting-place ID meet is connected, discharges the meeting-place, finishes charging etc., specifically may further comprise the steps:

Step 300～step 301: the closing session request message after conference management server will be changed passes through the MPTY meeting interface that NGN provides to the Web Portal to the IT network opening, send to WebPortal, Web Portal is transmitted to AS with the closing session request message that receives simultaneously, AS checking closing session request message is legal and enter step 302 after Web Portal returns closing session request success response synchronously, otherwise, return process ends behind the closing session request failure response synchronously.

Closing session request between conference management server and the Web Portal can adopt interface function to realize, such as definition closing session request interface function R eleaseConf () is:

String?ReleaseConf(String?strConfID，String?strCompereID)

Wherein, the parameter declaration in the ReleaseConf () function is as follows:

StrConfID: meeting-place ID is defined as character string type;

StrCompereID: host's Subscriber Number is defined as character string type.

Whether AS checking closing session request message is legal, if legal, then returns closing session request success response message synchronously, carries the session id of this Multi-Party Conference in this closing session request success response message; If illegal, then return closing session request failure response message synchronously, in closing session request failure response message, carry the reason-code that causes failure, such as: reason-code-1 expression system exception; It is illegal that reason-code-25 expression closing session request message carries parameter; Reason-code-30 expression meeting-place ID does not exist; Reason-code-31 expression host's Subscriber Number is not the corresponding host's of meeting-place ID a Subscriber Number; Reason-code-36 expression affairs are just busy, do not allow this user is operated or the like.

Hypothesis AS checking closing session request message is legal in this step, and promptly the Subscriber Number of host's correspondence of carrying in the closing session request message is consistent with current host and meeting-place ID with meeting-place ID.

Need to prove that above-mentioned ReleaseConf () function can just illustrate according to some parameter of user's needs increase/deletion here, be not used in restriction method of the present invention.

Step 302～step 310:AS initiates to discharge the connection of Media Stream passage, the release meeting-place of conference participation each side.

Specific implementation comprises: AS applies for playback to MRS, and the each side's meeting that participates in a conference with notice closes to an end, and returns the playback successful respond to AS after MRS finishes; After AS receives this playback successful respond, send the participant's request that discharges, after SoftSwitch release participant calls out connection, return the release participant to AS and reply to SoftSwitch; Then, AS sends the release participant to MRS and takies the Media Stream channel request, and MRS release participant's Media Stream passage also returns the release of participant's Media Stream passage to AS and replys; Afterwards, AS sends the host's request that discharges to SoftSwitch, after SoftSwitch release host calls out connection, returns the release host to AS and replys, last AS sends to MRS and discharges the meeting-place resource request, and MRS discharges all resources of meeting-place and returns the release meeting-place to AS and reply.

Step 311～step 312:AS is to the Web Portal state information of returning that meeting adjourned, and WebPortal will receive that meeting adjourned state information is transmitted to the conference management client and shows this information by conference management server simultaneously.

At this moment, the asynchronous event ID in the NotifyStatus () function is 7; State information can comprise: 0 represents successfully ,-1 expression system exception, and-2 expression host Subscriber Numbers do not exist, and-12 expression systems are overtime or the like.

So far, meeting adjourned for MPTY.

In addition, for dynamic adding/deletion participant in Multi-Party Conference carries out, the inventive method has also further provided concrete processing method.

Fig. 4 be the present invention a kind of in the MPTY meeting host initiatively add participant's flow chart, this process comprises by the conference management client end interface, the user imports the participant's information that needs adding, after conference management server receives and adds participant's information, this information translation for adding participant's request message, specifically be may further comprise the steps afterwards:

Step 400～step 401: conference management server will add participant's request message and pass through the MPTY meeting interface that NGN provides to the Web of IT network opening Portal, send to Web Portal, the adding participant request message that while Web Portal will receive is transmitted to AS, it is legal and return synchronously to add to Web Portal and enter step 402 after the participant asks success response that AS checking adds participant's request message, otherwise, return synchronously and add the participant and ask process ends behind the failure response.

Adding participant request message between conference management server and the Web Portal can adopt the interface function of http protocol carrying to realize, adds participant request interface function AddIntoConf () such as definition to be:

String?AddIntoConf?(String?strConfID，String?strCompereID，StringstrCallee，int?nCalleeRole)

Wherein, the parameter declaration in the AddIntoConf () function is as follows:

StrConfID: meeting-place ID is defined as character string type 1;

StrCompereID: host's Subscriber Number is defined as character string type;

StrCallee: the Subscriber Number that adds the participant of meeting; Here, strCallee is commonly defined as character string type, promptly once adds participant's request and can add a participant, also strCallee can be defined as the character string type array, promptly once adds participant's request and can add a plurality of participants simultaneously.

NCalleeRole: add meeting person role, be defined as integer.0 expression adds the participant by the host.1 expression is not that host's user initiatively applies for adding the meeting-place by the conference management client of self installing to conference management server.

Whether the AS checking adds participant's request message legal, if legal, then return the adding participant synchronously and ask success response message, and this adding participant asks to carry in the success response message session id of this Multi-Party Conference; If illegal, then return the adding participant synchronously and ask failure response message, the participant asks to carry in the failure response message reason-code that causes failure in adding, such as: reason-code-1 expression system exception; It is illegal that reason-code-25 expression closing session request message carries parameter; Reason-code-30 expression meeting-place ID does not exist; Reason-code-31 expression host's Subscriber Number is not the corresponding host's of meeting-place ID a Subscriber Number; Reason-code-36 expression affairs are just busy, do not allow this user is operated; This user of cause value-60 expression is in the meeting-place or the like.

It is legal that hypothesis AS checking adds participant's request message in this step, the Subscriber Number that promptly adds host's correspondence of carrying in participant's request message is consistent with current host and meeting-place ID with meeting-place ID, and the Subscriber Number of the participant's correspondence that adds is not in current meeting-place.

Need to prove that above-mentioned AddIntoConf () function can just illustrate according to some parameter of user's needs increase/deletion here, be not used in restriction method of the present invention.

Step 402～step 406:AS is according to adding the information of carrying in participant's request message, send participant's signaling that calling needs adding to SoftSwitch, SoftSwitch carries out this participant of calling after receiving this signaling, and return and call out the participant and reply, during replying, this carries the whether information of access success of participant; If success, AS with the meeting-place that this participant adds current meeting-place ID correspondence, behind the MRS adding participant, sets up the Media Stream passage by SoftSwitch to the MRS application between this participant and MRS.

This step realizes with step 212～step 216 in full accord, no longer repeats here.

Step 407～step 408:AS returns the participant to Web Portal and adds the meeting-place and reply, and Web Portal adds the meeting-place with the participant who receives and replys by conference management server and be transmitted to the conference management client and show this response message simultaneously.

At this moment, the asynchronous event ID in the NotifyStatus () function is 9; State information can comprise: 0 represents successfully,-1 expression system exception,-2 expression host Subscriber Numbers do not exist,-3 expression called numbers do not exist,-8 expression host's user balance or limit deficiencies,-11 expression called numbers use, and-12 expression systems are overtime, the called do-not-disturb functionality that is provided with of-16 expressions, refusal is called out,-17 expression Called Busy, the called no response of-18 expressions ,-19 expressions are called to be spacing, called can't the connection of-21 expressions,-53 expression meeting-place inadequate resources ,-61 expression users add the meeting-place failure ,-62 expression user on-hooks or the like.

So far, successfully added the participant.

Except that adding participant's shown in Figure 4 method, also can be by the user terminal in the IP bearer network by dialing default adding Multi-Party Conference access code, add active conference by SoftSwitch to the AS application, after AS returns to the conference management client with this user terminal information and gets the nod, this user terminal is joined in the current meeting-place according to the described flow process of Fig. 4.Here AS returns to the conference management client with this user terminal information and belongs in conversation procedure, and AS is initiatively to the conference management server reported event.

For in conference process, AS can initiatively require to add the meeting-place request with above-mentioned user terminal and the conference site state that monitors reports conference management server, has defined reporting events interface function ReportMessage ().

String?ReportMessage(String?strSessionID，int?nEventID，String?strConfID，String?strUserID，String?strStatus，String?strDescription)

Wherein, the parameter declaration in the ReportMessage () function is as follows:

StrSessionID: session id, be defined as character string type, this unique ID that calls of the sign that produces during the AS reported event, conference management server use this session id sign when reported event is carried out asynchronous replying.

NEventID: event id, be defined as integer, be used to identify the incident that reports.

StrConfID: meeting-place ID, be defined as character string type, when the meeting-place is created successfully, this parameter will be returned unique identification id in new establishment meeting-place.

StrUserID: Subscriber Number, be defined as character string type, this parameter is deposited the number that needs return state.

StrStatus: state value, be defined as character string type, at each reported event ID different state values is arranged, be that success, system exception or system are overtime or the like such as the state of certain reported event ID correspondence.

StrDescription: the descriptor of state value correspondence is defined as character string type.Such as being used to failure cause that specifically describes certain reported event ID correspondence etc.

Each parameter basically identical of NotifyStatus () function in the definition of each parameter and the step 210～step 211 in above the ReportMessage () function, the main distinction is, in the ReportMessage () function, event id and event description are the active reported event, such as: 104 expression conference background sounds finish; 106 expression participant on-hooks; 107 expression participant expense deficiencies walk out; 108 expression host on-hooks, meeting continues; 109 expression host on-hooks, meeting finishes automatically; 110 expression host expense deficiencies, meeting finishes automatically; 111 expression meeting abnormal endings; 112 expression meeting-place number deficiencies or host be not in the meeting-place, and meeting finishes or the like automatically.

Need to prove that above-mentioned ReportMessage () function can just illustrate according to some parameter of user's needs increase/deletion here, be not used in restriction method of the present invention.

Fig. 5 be the present invention a kind of in the MPTY meeting host initiatively delete participant's flow chart, this process comprises by the conference management client end interface, the user imports the participant's information that needs deletion, after conference management server receives deletion participant information, this information translation is deletion participant request message, specifically may further comprise the steps afterwards:

Step 500～step 501: the deletion participant request message after conference management server will be changed passes through the MPTY meeting interface that NGN provides to the Web of IT network opening Portal, send to WebPortal, the deletion participant request message that while Web Portal will receive is transmitted to AS, AS checking deletion participant request message is legal and return synchronously to Web Portal and to enter step 502 after the deletion participant asks success response, otherwise, return the deletion participant synchronously and ask failure response.

Deletion participant request message between conference management server and the Web Portal can adopt interface function to realize, such as definition deletion participant request interface function KickOutFromConf () is:

String?KickOutFromConf(String?strConfID，String?strCompereID，StringstrCallee)

Wherein, the parameter declaration in the KickOutFromConf () function is as follows:

StrConfID: meeting-place ID is defined as character string type;

StrCompereID: host's Subscriber Number is defined as character string type;

StrCallee: the participant's of deletion meeting Subscriber Number; Here, strCallee is commonly defined as character string type, promptly once deletes participant's request and can delete a participant, also strCallee can be defined as the character string type array, promptly once deletes participant's request and can delete a plurality of participants simultaneously.

Whether AS checking deletion participant request message is legal, if legal, then return the deletion participant synchronously and asks success response message, and this deletion participant asks to carry in the success response message session id of this Multi-Party Conference; If illegal, then return the deletion participant synchronously and ask failure response message, the participant asks to carry in the failure response message reason-code that causes failure in deletion, such as: reason-code-1 expression system exception; It is illegal that reason-code-25 expression closing session request message carries parameter; Reason-code-30 expression meeting-place ID does not exist; Reason-code-31 expression host's Subscriber Number is not the corresponding host's of meeting-place ID a Subscriber Number; Reason-code-36 expression affairs are just busy, do not allow this user is operated; Cause value-98 expression quiescing, such as the Subscriber Number correspondence that requires to delete is host or the like.

Hypothesis AS checking deletion participant request message is legal in this step, the Subscriber Number of promptly deleting host's correspondence of carrying in participant's request message is consistent with current host and meeting-place ID with meeting-place ID, and the Subscriber Number of participant's correspondence of deletion is not host's Subscriber Number and is present in the current meeting-place.

Need to prove that above-mentioned KickOutFromConf () function can just illustrate according to some parameter of user's needs increase/deletion here, be not used in restriction method of the present invention.

Step 502～step 507:AS applies for playback to MRS, and the participant of the each side's deletion appointment that participates in a conference with notice returns to AS MRS finishes after and deletes the participant and reply; After AS receives that this deletion participant replys, send the connection request that disconnects the participant that need delete, after SoftSwitch release needs the participant of deletion to call out connection, return the disconnection connection to AS and reply to SoftSwitch; Then, the Media Stream channel request that the participant that AS need delete to MRS transmission release takies, MRS release need be deleted participant's Media Stream passage and be returned the release of disconnection Media Stream passage to AS and reply.

Step 508～step 509:AS returns the deletion participant to Web Portal and replys, and the deletion participant that while WebPortal will receive replys by conference management server and is transmitted to the conference management client and shows this information.

At this moment, the asynchronous event ID in the NotifyStatus () function is 10; State information can comprise: 0 represents successfully ,-1 expression system exception, and-2 expression host Subscriber Numbers do not exist, and-3 expression called numbers do not exist, and-12 expression systems are overtime ,-62 expression users on-hook etc.

So far, successfully deleted the participant.

Description from above the inventive method, as can be seen, the invention provides the IT network user and insert the NGN network, initiate, manage the MPTY meeting between the multiple communication network users according to the conference management request that the IT network user is provided with by the AS among the NGN by conference management client software and conference management server.Wherein conference management capabilities comprises: initiate meeting, closing session, dynamically add the side of participant in meeting, in the deletion meeting, and management reported event initiatively, pass through the access code request as third party in the meeting and add in meeting-place, the AS monitoring meeting each side's connection status etc.

The invention provides by the IT network user instant initiate and communication network users between the ability of media conference in many ways, can realize the multimedia collaborative meetings such as data, voice, video of Internet or other IT Networks and Communications net based on this method.
