  • the method for joining the cluster conference in the embodiment of the present invention is that after the sound collection and reception is completed, if the target is determined If the conference is not held locally, the global conference manager is first sent a query for the deployment of the conference. After the conference is deployed, the new INVITE call initiated by the bridge relay is directly sent to the SIP server where the conference is deployed.
  • a new INVITE call is initiated to the SIP distributor to act as a bridge relay.
  • the SIP distributor queries the global conference manager to determine the conference deployment, the SIP distributor then routes the new INVITE to the SIP where the conference is deployed.
  • the server sends a query to the global conference manager to query the conference deployment request.
  • the new INVITE call that acts as the bridge relay is sent to the SIP server where the conference is deployed.
  • an embodiment of the present invention further provides a global conference manager, including:
  • a conference number assigning unit 81 configured to allocate a globally unique conference number to the conference to be created according to information to be created;
  • the conference deployment query unit 82 is configured to query the SIP application server information where the conference is deployed according to the information to be joined to the conference;
  • the global conference indexing unit 83 is configured to maintain the conference number assigned by the conference number assignment unit 81 and provide a query for the conference deployment for the conference deployment query unit 82.
  • the global conference manager provided by the embodiment of the present invention, still referring to FIG. 8, further includes:
  • a request request receiving unit 86 configured to receive a create conference request, where the create request carries information about a conference to be created by the user side;
  • the query request receiving unit 88 is configured to receive a query meeting deployment request, where the query request carries information that the user side wants to join the conference.
  • the global conference manager provided by the embodiment of the present invention allocates a unique conference number to the conference to be created by the conference number assignment unit 81, and queries the global conference index unit 83 to obtain the global conference deployment information through the conference deployment query unit 82, so that the present invention
  • the embodiment can implement the establishment and joining scheme of the IMS cluster conference. Compared with the prior art, the user needs voice dialing to join the IMS cluster conference.
  • the SIP server can be bridged to the conference deployment, which effectively solves the problem of the prior art voice dialing joining the cluster conference, and can adapt to the technical requirements for the large-scale expansion of the IMS cluster conference service capacity.

Abstract

L'invention concerne un procédé, un appareil et un système pour créer et rejoindre le sous-système multimédia IP (IMS), qui appartiennent au domaine de la télégraphie et peuvent résoudre efficacement le problème consistant à rejoindre une conférence de groupe par la composition vocale dans l'art antérieur, et permettent aux utilisateurs de rejoindre normalement la conférence lorsque la lecture du son et la réception du numéro de téléphone sont demandées pour rejoindre la conférence de groupe IMS. Par comparaison à l'art antérieur, le système obtenu par les modes de réalisation de la présente invention ajoute un gestionnaire de conférences globales, qui sert à distribuer un numéro de conférence unique globalement à la conférence à créer, et stocker le numéro de conférence dans la table d'index de conférences globales; et rechercher les informations du serveur de protocole d'ouverture de session (SIP) sur lequel la conférence se déroule selon les informations de la conférence à rejoindre. La solution technique du mode de réalisation de la présente invention peut s'adapter aux exigences techniques du dispositif d'extension à grande échelle pour la capacité de service de conférences de groupe IMS.
