Title (EN) MEDIA USER AGENT AND MEDIA BACK-TO-BACK USER AGENT LAYERS
(FR) COUCHES D'AGENT D'UTILISATEUR MULTIMÉDIA DE BOUT EN BOUT ET AGENT D'UTILISATEUR MULTIMÉDIA
Abstract:
(EN) A method of processing session initiation protocol (SIP) call flows, the method comprising, at a back-to-back user agent (B2BUA) configuring a media user agent (UA) layer to interface between a SIP UA layer and a Media B2BUA layer. For call flow operation in the SIP UA layer to Media B2B UA layer direction, the configuring comprises, at the media UA layer first mapping each message received from the SIP UA layer comprised of one of a plurality of SIP layer message types into one of a SDP offer message type, a SDP answer message type and a third message type different from the SDP offer message and SDP answer types, and passing each first mapped message to the Media B2B UA layer for processing.
(FR) L'invention concerne un procédé de traitement de flux d'appel en protocole d'initiation de session (SIP), le procédé consistant à, au niveau d'un agent d'utilisateur de bout en bout (B2BUA), configurer une couche d'agent d'utilisateur multimédia afin de former une interface entre une couche UA SIP et une couche B2BUA multimédia. Pour une opération de flux d'appel dans la couche UA SIP en direction de la couche UA B2B multimédia, la configuration comprend, au niveau de la couche UA multimédia, une première mise en correspondance de chaque message reçu de la couche UA SIP constitué d'un type parmi une pluralité de types de message de couche SIP dans un type de message d'offre SDP, un type de message de réponse SDP et un troisième type de message différent du message d'offre SDP et des types de réponse SDP et le fait de faire passer chaque premier message mis en correspondance à la couche UA B2B multimédia pour traitement.
