  • the present invention relates to the field of multimedia technologies, and in particular, to a method for selecting a terminal to join a conference, a method for controlling a terminal to select a conference, an access server, a terminal device, a media control server, and a system for selecting a conference. BACKGROUND OF THE INVENTION With the continuous development of modern enterprises, more and more enterprises are willing to choose a multimedia conference system to hold multimedia video conferences.
  • the multimedia conference system includes a management server, an access server, and a plurality of media control servers (for example, an MCU, a Multipoint Control Unit, and a multipoint control unit in the H.323 protocol) and a terminal; a management server, which can be defined to participate. From the venue, you can also define meeting resources.
  • a terminal can participate in multiple conferences at different times, but can only participate in one conference at a time. If a terminal needs to participate in a conference, it can be implemented by calling the conference number. It can also be implemented by the management server calling the site corresponding to the known conference number.
  • terminal access can be achieved in two ways:
  • Terminal access is achieved by calling a conference.
  • the terminal needs to know the conference number in advance.
  • the method of obtaining the conference number is usually that the conference convener notifies the conference terminal manually or by mail before the conference is held.
  • the process of the terminal participating in the conference (that is, the process of terminal joining) is:
  • the terminal After the terminal learns the conference number to be joined, the terminal sends a request to the access server to request the media control server address where the called conference number is located; the access server resolves the media control server address, and obtains the address of the conference site corresponding to the conference number learned by the terminal. , that is, the destination address; after the access server resolves successfully, returns the correct destination address to the terminal, and the terminal directly sends a call request to the media control server corresponding to the destination address, and the media control server answers the call after receiving the call request. After the law is verified, the terminal is allowed to join.
  • the drawback of this method is that the terminal can only join the meeting according to the conference number that is known in advance, and does not choose the opportunity to join the conference, which limits the freedom of the terminal to join the conference; further, since the terminal needs to obtain the conference number manually, the efficiency is low, and it is prone to leakage.
  • the terminal does not need to know the conference number, but the terminal calls a special service number (referred to as a special service number), and the access server identifies which conference number the special service number corresponds to, and the terminal is guided to enter the corresponding The specified conference, that is, after the terminal registers with the access server, the access server is responsible for resolving the conference number according to the special service number, and the access server automatically guides the terminal to enter the pre-designated conference.

Abstract

La présente invention concerne, dans des modes de réalisation, un procédé destiné à un terminal participant sélectivement à une conférence, un procédé destiné à commander un terminal participant à une conférence, un serveur d'accès, un dispositif terminal et un serveur de commande de média afférent, ainsi qu'un système destiné à un terminal participant sélectivement à une conférence. Ledit procédé destiné à un terminal participant sélectivement à une conférence comprend : l'acquisition de l'information de toutes les conférences auxquelles le terminal est capable de participer ou de souscrire; la sélection d'un identifiant de conférence pour la conférence à laquelle il est nécessaire de participer ou de souscrire, à partir de l'information de toutes les conférences auxquelles le terminal est capable de participer ou de souscrire; l'initiation d'un appel d'accès à une conférence, passé à l'identifiant de conférence sélectionné. Ainsi, le problème de l'état de la technique selon lequel un terminal ne peut pas participer sélectivement à une conférence est résolu. Le degré de liberté du terminal participant à une conférence est amélioré; les utilisateurs peuvent sélectivement participer à différentes conférences indépendamment, ce qui leur permet d'organiser raisonnablement différentes conférences.
