Description

System and method for supporting multimedia conference reservation

technical field

The invention relates to a system and method for supporting multimedia conference reservation, in particular to a system and method for multimedia conference reservation initiated by a server and supporting multiple access modes. the

Background technique

In today's high-paced life, fast and effective communication and exchanges have become people's basic needs; with the rapid development of the world economy, business activities of companies and their departments distributed around the world are becoming more and more frequent, and meetings and exchanges are inevitable. Compared with face-to-face meetings in traditional meeting rooms, in most cases people prefer to use modern communication means to hold meetings to save travel time and meeting costs. the

The traditional public switched telephone network (PSTN for short) or mobile network can provide simple conference calls, but it can only provide conferences based on voice and video, and there are also problems such as small capacity, conference management, and weak control functions. limitations, so it has not been well applied. Although the simple conference bridge has enhanced functions, it still has disadvantages such as expensive equipment, single access means, and only supports voice, including:

First, the access method is single, limited to fixed telephones or mobile terminals, resulting in only sound but not graphics, which is obviously far from enough for modern conferences that are full of data structure analysis and development status grasp of;

Second, the control function of the conference bridge is not strong. After the conference host logs in, the participants can be notified separately according to the conference host's instructions, which causes a waste of time and may also affect the meeting due to the lack of personnel. process, therefore, the effect of scheduled meetings is not good;

Second, there is a single way for participants to join the meeting. They are all based on the invitation of those who have joined the meeting, and they can only enter after providing a user name/password to log in. This input confirmation mechanism also brings time delays.

To sum up, as far as the current technology is concerned, there is no system and method for efficiently reserving a multimedia conference that can support multiple access modes. However, with the emergence of the IP Multimedia Subsystem (IMS) in the Next Generation Internet (NGN), it is possible to overcome the above problems. This is because, based on the characteristics of IMS itself, it can realize multiple access Ways, such as WEB/WAP, PC client, Interactive Voice Response (Interactive Voice Response, IVR for short), mobile terminal voice/short message, etc., the present invention supports multimedia conference reservation based on the functions that can be realized by network development systems and methods. the

The present invention also provides a method for supporting multimedia conference reservation, comprising the following steps:

Step 1. The conference application server receives a conference reservation request, which includes conference policy setting information and participant terminal information;

Step 2, the conference application server determines the conference type according to the conference policy setting information, and creates a conference site;

Step 3. The conference application server requests the media resource server to reserve corresponding media resources according to the terminal information of the participants. If the resource reservation is successful, execute step 4, otherwise end;

Step 4, the conference application server sends a conference notice to the participating terminals;

Step 5. When the conference reservation time is reached, the conference application server initiates a join conference instruction to the participating terminals through the IP multimedia subsystem;

Step 6. The terminal that receives the join conference instruction joins the conference;

Step 7. The terminal that has joined the conference initiates an invitation to the conference application server for terminals outside the user list;

Step 8, the conference application server applies to the media resource server for the media channel of the current conference type;

Step 9, the conference application server initiates an invitation to a terminal outside the user list, and obtains the media information of the terminal;

Step 10, the conference application server applies to the media resource server to convert the type of the media channel according to the media information, and if successful, the media resource server returns the media channel information to the conference application server;

Step 11, the conference application server initiates an instruction to join a conference to the terminal;

Step 12, the terminal joins the meeting. the

Further, the received terminal information in step 1 is a user list, and the user list includes the notification method of the participant terminal, and the notification method includes but not limited to the IP address of the PC terminal, the number of the mobile terminal, and the fixed terminal And the client user name of the PC terminal and/or mobile terminal. the

Alternatively, the terminal information received in step 1 is group information. Then before the step 2, it also includes: the conference application server queries the group management server according to the group information to obtain a user list, and the user list includes the notification method of the participating terminals, and the notification method includes but is not limited to PC terminal The IP address of the mobile terminal, the number of the fixed terminal, and the client user name of the PC terminal and/or mobile terminal. the

The step 2 is specifically: the conference application server determines the conference type as audio conference, video conference or data conference according to conference policy setting information; and creates a conference site, including creating a conference number and/or password, conference start/end time, Conference participants and notification methods. the

The step 3 is specifically:

Step 31, the conference application server requests the media resource server to reserve venue resources, and the request includes the type and quantity of media channels;

Step 32, the media resource server performs a resource query according to the request, and if the current resource satisfies the request, execute step 33, otherwise return a reservation failure message and end;

Step 33: The media resource server returns media channel information to the conference application server, and sends reservation success information to the conference application server. the

The step 33 also includes: the conference application server feeds back reservation success information to the conference initiating terminal. the

The step 6 may specifically be that the terminal that has received the instruction to join the conference directly responds to the instruction to join the conference, and establishes a link to the multimedia conference. the

Alternatively, the meeting notice in step 4 includes the site identifier, and the site ID is conference number information or conference number and password information. the

Then after the step 5, it also includes:

Detailed ways

The invention provides a system and method for supporting multimedia conference reservation, thereby overcoming the defects of single access form, creation of conference bridges one by one and single form of joining conference in the prior art. The system and method for supporting multimedia conference reservation provided by the present invention will be described in detail below.

Referring to Fig. 1, it is a block diagram of the system embodiment 1 supporting multimedia conference reservation provided by the present invention, including:

Media Resource Server (MRS for short) 1 is used to provide media resources through media stream distribution according to different types of conferences, and control the occupancy and flow of corresponding media resources;

A conference application server (Conference Application Server, referred to as Conference AS) 2 is used to receive a conference reservation request and a site policy; it is also used to request the MRS1 to reserve media resources according to the received conference reservation request, and to make a conference reservation Monitoring, such as conference creation, site deletion, and site status release, etc. the

However, when initiating the join conference command, in order to support multiple terminals, media streams must be sent and received via the IMS network, that is, the join conference command is sent to the participating terminals 5 through the IMS network to establish a session connection. In this way, multiple different types of terminals 5 can participate in the meeting at the same time. For example, it can be a PC client software for multimedia conference services. After installing the client software on the personal computer, the user can use the service by changing the client software, and can Support various conference types such as audio, video, and data through the IMS network; it can also be an ordinary terminal in the circuit domain, and can be compatible with audio services after accessing multimedia conferences. the

The message server (Message Server) 3 receives the conference reservation notification issued by the conference application server 2 and sends it to the participating terminals, for example, by instant messaging, email and short message. Those skilled in the art should understand that the message server 3 in this embodiment is only a form of support for issuing conference reservation notices without limitation, such as when the system supporting multimedia conference reservation provided by the present invention has a voice service function , you can also directly release the scheduled meeting notice. the

In this system, the conference application server 2 can integrate the functions of the service Porta] portal, directly provide a path for conference reservation and conference site policy setting, and provide a path for the distribution of conference reservation notices; Gateway 4 (not shown in the figure) realizes this function. Whether it is the service Portal portal or the service network management 4 assembled in the conference application server 2, it can provide support for the IP network or mobile communication network or telecommunication network, and send the notification information to the user terminal 5. For example, users can directly reserve conferences and set site policies using the http protocol on the service portal or service gateway, or reserve conferences and set site policies through the Session Initiation Protocol (SIP for short). the

Referring to FIG. 2 , it is a block diagram of Embodiment 2 of the system supporting multimedia conference reservation provided by the present invention. On the basis of Embodiment 1, it further includes a service gateway 4 for providing a path for conference reservation and site policy setting, and for Provides a path for sending scheduled meeting notifications. the

Referring to FIG. 3 , it is a block diagram of Embodiment 3 of the system supporting multimedia conference reservation shown in FIG. 1 , taking the service gateway 4 not integrated in the conference application server as an example. In addition to including the module described in Embodiment 1, it also includes a group management server (Group Management Server, referred to as GMS) 6, which is used to complete the management of group information according to the instructions of the conference application server 2, such as the user list Create, modify and query. the

It also includes a Network Management Server (NMS for short) 7, which is used to manage and maintain the network element performance provided by MRS1, including topology information, alarms, logs, maintenance, configuration, and statistics of each network element. And provide feedback to the conference application server 2; in this way, the availability of media resources provided by MRS1 can be fully guaranteed. the

The conference application server 2 is connected with a business management system (Business Management Server, referred to as BMS) 8, and the BMS 7 is a supporting facility in the existing network, which is used to perform storage and provision of user information, and support for communication network application services And the corresponding billing functions, such as loading and publishing services, user account opening, account cancellation, and corresponding billing settings. Wherein, the BMS 7 particularly includes an IMS user information server (Home Subscriber Server, referred to as HSS) 9, which is used to store the basic information of the IMS user and provide routing support for the conference application server 2 and the user terminal 5 to establish a session. the

Referring to Fig. 4, it is a block diagram of a specific embodiment of the conference application server 2, under the situation that the conference application server 2 integrates the service Portal portal function, the conference application server 2 includes;

Policy control module 2a, configured to configure and load conference policies;

The conference center module 2b is connected with the policy control module 2a, and is used to request MRS1 to reserve media resources and monitor the conference according to the received conference reservation request and site strategy; specifically, the conference center module 2b can further It is divided into three functions: venue control, media control, and user control. It is responsible for maintaining the signaling relationship between each participant in the conference, ensuring that each participant can receive media streams, and also responsible for implementing conference policies;

The conference application gateway 2c is connected with the conference center module and the policy control module, and is used to realize the service portal function, and sends the received venue policy setting instruction to the policy control module 2a, and sends the conference reservation request to the conference center module 2b, and send the information sent by the conference center module 2b. the

In order to realize the notification of the status of the venue, the preferred solution is to also include a venue information publishing module 2d, the conference center module 2b is connected with the conference application gateway 3c through the venue information publishing module 2d, and the venue information publishing module 2d is used to receive the conference site status and the join/exit events of conference members, and notify the terminals that have subscribed to the conference site information through the conference application gateway 2c. the

Those skilled in the art should understand that if the conference application server 2 does not integrate the service portal function, the conference application gateway 2c will not be included, and the service gateway 4 will provide support for the routing function. the

It can be seen from the above embodiments that when a multimedia conference is reserved, the session mechanism of the conference application server can be actively established to overcome the defects of creating conference bridges one by one in the prior art; at the same time, the session can be directly established through the IMS network to achieve Multiple access methods are supported. the

Referring to Fig. 5, it is a flow chart of the method for supporting multimedia conference reservation provided by the present invention, including the following steps:

Step 1. The conference application server receives a conference reservation request, which includes conference policy setting information and participant terminal information;

Step 2, the conference application server determines the conference type according to the conference policy setting information, and creates a conference site;

Step 3. The conference application server requests the MRS to reserve corresponding media resources according to the terminal information of the participants. If the resource reservation is successful, execute step 4, otherwise end;

Step 4, the conference application server sends a conference notice to the participating terminals;

Step 5. When the scheduled meeting time is reached, the meeting application server sends an instruction to join the meeting to the participating terminals through the IMS;

Step 6. The terminal that receives the instruction to join the conference joins the conference. the

Since the conference application server is relatively independent of the IMS network, the present invention is not limited to making reservations through the IMS network, so that before step 1 of the present invention, the PC client or mobile terminal or fixed terminal or other devices capable of video and audio communication can use WEB or WAP or Short Message System (Short Message System, SMS for short) or IVR or other forms of communication, through the service portal to send conference reservation requests to the conference application server, for example, PC clients/mobile terminals can use the Portal in the form of WEB Send a conference reservation request; both mobile terminals and fixed terminals can send a conference reservation request in the form of IVR through the agent system (Presence), and the operator will complete the reservation process on the business portal; Direct access; in this way, existing network resources, such as IP networks, 2G, 3G networks or LAN networks, can be fully utilized without occupying the bandwidth of the IMS network. the

Wherein, the conference initiating terminal may not provide participant information when scheduling a conference, but notify when the conference is held, but this is obviously not a better technical solution. Participant information can be provided in the following two ways, one is that the participant terminal information received in step 1 is a user list; the other is that the participant terminal information received in step 1 is group information. the

For the case of group information, it is required to include before step 2: the conference application server queries the group management server according to the group information to obtain the user list. The user list is pre-stored in the group management server, such as the user's "friends" group, "colleagues" group, and the like. the

The notification method of the participating terminals is included in the user list, and the notification method includes but not limited to the IP address of the PC terminal, the numbers of the mobile terminal and the fixed terminal, and the client user name of the PC terminal and/or mobile terminal. the

Further, the present invention can provide instant meeting and reserved meeting. For example, a user applies for creating a conference, sets the conference theme, and the conference application server creates a conference site and adds the user to the conference. As the conference initiator, the user is defaulted as the host of the conference, and after successfully creating the conference site, the user is automatically subscribed to the status information of the conference site, that is, when the site status changes, the user will receive a notification. If the application for creating an instant conference, the site will be created immediately; otherwise, the site will be created after the preset time. the

Instant conference is generally called Ad-hoc mode, which refers to a conference that does not need to be scheduled and has a relatively free form. the

Apparently, the difference between the IMS-based multimedia conference reservation method provided by the present invention and the traditional method for creating a conference is that the establishment of a session through the IMS can provide support for various terminals, thus expanding the ways and degrees of freedom of participation ; At the same time, the conference application server actively creates a conference and notifies the participants on the user list, avoiding the cumbersome process of inviting one by one by the moderator, and then notifying one by one by the conference application server and establishing a conference bridge. the

In step 1, the meeting request can include the following content in addition to the participant information: set the start time and end time of the meeting, the meeting participants, whether to allow users outside the participant list to join the meeting site, the maximum participant Number of meetings, meeting types (audio, video, data), notification methods of meeting information and meeting agenda. the

The step 2 is specifically: the conference application server determines the conference type as audio conference, video conference or data conference according to the conference policy setting information; , the participating terminal and notification method of the meeting. the

In the method provided by the present invention, the operation of the conference application server to create a conference site includes the following steps:

Step 31, the conference application server requests the media resource server to reserve venue resources, and the request includes the type and quantity of media channels;

Step 32, the media resource server performs a resource query according to the request, and if the current resource satisfies the request, execute step 33, otherwise return reservation failure information and end;

Step 33: The media resource server returns media channel information to the conference application server, and sends reservation success information to the conference application server. the

In addition, step 33 further includes: the conference application server feeding back reservation success information to the conference initiating terminal. the

It can be seen that creating corresponding media channels for different types of participating terminals avoids the problem of reserving a large amount of resources simply according to the type of meeting. For example, for a video conference, only some of the participating terminals, such as PC clients, can Support video, and in some cases, limited to the environment at the time, such as ordinary terminals with only circuit domains, it may only support audio or data, so it is obvious that a large number of video resources reserved by the participants will be This results in a waste of resources. Therefore, resource reservation according to the types of participating terminals can achieve the purpose of saving IMS network resources. the

When notifying the participating terminals, the notification method is not required to occur in the IMS network, but may include but not limited to email or short message or instant message or WAP or PUSH MAIL. the

The content of the notification includes the identifier of the meeting site, and also includes the convener, the participants, the subject of the meeting, the time of the meeting, the type of the meeting, and the number of participants in the meeting. Wherein, the site identifier is a meeting number and/or password information. the

When the scheduled time arrives, the conference application server sends an instruction to join the conference to the participating terminals through the IMS, including calling the corresponding mobile/fixed phone terminal according to the notification method, or establishing a connection with the PC client. Once the terminal responds, such as pressing the answer key, join the conference. the

Through the addition of the site ID, in the above method, even if the participant fails to respond in time, including not receiving the conference instruction in time, or there are other terminals that are more suitable for participating in the multimedia conference than the terminal that received the conference instruction, it can be used in any subsequent Time, use any terminal to join. As shown in Figure 6, including:

Step 61. The terminal that fails to respond to the join conference instruction in time requests to join the conference by inputting the conference number or the conference number and password;

Step 62, the conference application server obtains the media information of the terminal, and inquires whether there is a change compared with the media information in the user list, if yes, execute step 63, otherwise execute step 64;

Step 63: The conference application server applies to the media resource server to convert the type of the original reserved media channel according to the media information. If successful, the media resource server returns the media channel information to the conference application server, and executes the steps 64, otherwise return the reservation failure command and end;

Step 64, the conference application server initiates an instruction to join a conference to the terminal;

Step 65, the terminal joins the conference. the

For data-based multimedia conferences, users can choose to access through mobile terminals or PDAs, which have good mobility; for video-based conferences, users can choose to access through PC terminals to ensure video quality and avoid occupying too much space. more wireless bandwidth. It is one of the advantages of the present invention that it can support multiple access modes such as mobile terminals and PC terminals at the same time. the

In addition, the present invention also supports terminals that have joined the conference to invite terminals outside the user list to join the conference, as shown in Figure 7, after step 6, it also includes:

Step 71, the terminal that has joined the conference initiates an invitation to the conference application server for terminals outside the user list;

Step 72, the conference application server applies to the media resource server for the media channel of the current conference type;

Step 73, the conference application server initiates an invitation to a terminal outside the user list, and acquires the media information of the terminal;

Step 74. The conference application server applies to the media resource server for converting the type of the media channel according to the media information. If successful, the media resource server returns the media channel information to the conference application server, and executes step 75 , otherwise return the reservation failure command and end;

Step 75, the conference application server initiates a join conference instruction to the terminal;

Step 76, the terminal joins the conference. the

The present invention also supports terminals outside the user list to actively join the conference. For example, for some open conferences, other terminals can obtain the conference number by querying the current conference list. Referring to Fig. 8, be to also comprise following steps after method step 6 provided by the present invention:

Step 71', the terminal that has not received the conference notice actively requests to join the conference, and the request carries the media information of the terminal;

Step 72', the conference application server applies to the media resource server for a channel corresponding to the media information;

Step 73', the media resource server reserves the media channel, if the reservation is successful, the media resource server returns the media channel information to the conference application server, and executes step 74', otherwise returns a reservation failure instruction ,Finish;

Step 74', the conference application server initiates an instruction to join the conference to the terminal;

Step 75', the terminal joins the conference. the

Further, the method further includes the terminal that has joined the conference sending an instruction to the conference application server to subscribe to the conference site status; when the conference site status changes, the conference application server sends a notification to the terminal that has subscribed to the conference site status. the

A better technical solution is that the conference application server monitors the status of the conference site and releases unoccupied media channels at any time to ensure the maximum utilization of resources. the

The method for supporting multimedia conference reservation provided by the present invention will be described below through specific embodiments. the

Example 1:

Referring to Figure 9, it is an embodiment of implementing an instant meeting by applying the method provided by the present invention, including the following steps:

Step 101, PC terminal A sends a conference reservation request through the Portal, including information that the venue attribute information is video conference and the reservation time is real-time information, and also includes a user list, giving mobile terminals B and C, PC terminals A and D, and fixed terminals E's Session Description Protocol (Session Description Prottol, referred to as SDP);

Step 102, the conference application server receives the reserved conference request;

Step 103, the meeting application server determines that the meeting type is a video meeting, and creates a meeting place, including setting a meeting number and a password for the reserved meeting place;

Step 104, the conference application server requests the media resource server to reserve venue resources according to the SDP, including creating audio media channels for mobile terminals B and C and fixed terminal E, and creating video media channels for PC terminals A and D; wherein, the conference application server In the SDP provided to MRS, if the address of line c is set to 0.0.0.0 (IP4), it means that this port is not used to establish a video media channel; 

Step 105, the media resource server performs a resource query, and if the current resource satisfies the resource requirements of the venue, then execute step 106, otherwise return reservation failure information and end;

Step 106, the media resource server reserves venue resources, and sends reservation success information to the conference application server;

Step 107, the conference application server feeds back the reservation success information to the terminal A that reserved the conference, and sends the terminal on the user list, including mobile terminals B and C, and PC terminal A, to the terminals on the user list through PUSH MAIL according to the preset notification method and D, the fixed terminal E initiates a meeting notification, and the joining meeting notification includes the meeting number and password of the meeting;

Step 108, because it is an instant meeting, that is, the reservation time is current, so the meeting application server immediately initiates an instruction to join the meeting to the terminal through the IMS network;

Step 109: Part of the terminals receiving the instruction to join the meeting join the meeting, including PC terminal A, mobile terminal B and fixed terminal E, and join the meeting immediately; but the user of mobile terminal C does not respond immediately because he thinks that the video conference is more suitable for PC terminals ; while the user of PC terminal D did not receive it in time;

Step 110, terminals A and B subscribe to the site status;

Step 111, the user of mobile terminal C uses a PC terminal and PC terminal D to establish a link to the venue using the meeting number and password in the meeting notice after a certain delay;

Step 112, the conference application server sends a notification to terminals A and B that C and D join. the

Through the above embodiment, the instant meeting process is completed. This embodiment is not only applicable to instant conferences, but also applicable to conferences reserved for a certain time. The difference is that for instant conferences, an instruction to join the conference is sent immediately, while for conferences reserved for a certain time, the instruction to join the conference is not activated until the scheduled time. the

Example 2:

Referring to Fig. 10, it is another specific embodiment of applying the method of the present invention, comprising the following steps:

Step 201, the mobile terminal B sends a meeting reservation request through SMS, including the site attribute information is video conference and the reservation time is real-time information, and also includes group information;
