Title (EN) TRANSMISSION MODE SELECTION MECHANISM
(FR) MÉCANISME DE SÉLECTION DE MODE DE TRANSMISSION
Abstract: front page image
(EN)A method of selecting a transmission mode for media associated with a Push to talk Over Cellular, PoC, call involving a PoC Group. The method comprises, at a PoC Server implementing a participating PoC function associated with a PoC Client of said PoC Group, receiving from a controlling PoC function an indication that transmission mode selection rights are delegated to the participating PoC function (3,7). Thereafter, the participating PoC function makes a transmission mode selection (9) and, if the selection is that of a multicast or broadcast transmission mode, sends a re-invite to a multicast/broadcast bearer to said PoC Client (12).
(FR)L'invention porte sur un procédé de sélection d'un mode de transmission pour du contenu multimédia associé à un appel de messagerie vocale instantanée (« Push to talk Over Cellular », PoC) impliquant un groupe PoC. Le procédé comprend, au niveau d'un serveur PoC mettant en œuvre une fonction PoC participante associée à un client PoC dudit groupe PoC, la réception en provenance d'une fonction PoC de commande d'une indication que des droits de sélection de mode de transmission sont délégués à la fonction PoC participante (3, 7). Ensuite, la fonction PoC participante effectue une sélection de mode de transmission (9) et, si la sélection est celle d'un mode de transmission en multidiffusion ou en diffusion, envoie une réinvitation à un support de multidiffusion/diffusion audit client PoC (12).
