Method of implementing session blind transferring service and conference service interaction

Abstract

A method used to realize the conversion blind call transfer and the conference interaction, which are applicable to the IP multi-media sub system, comprising step (a)the blind call transfer is available for the user equipment (UE-A); as UE-A establishes the conference, the blind call transfer service equipment SE records the conference contact address of this conference service and marks UE-A as the original founder of the conference; (b) when UE-a asks the other conversation connection such as UE-B to transfer the target to the respective conference contact address, the address part of the transferred target will not be changed; also, the transfer request is transmitted to UE-B; or, blind call transfer logic shall be executed. For the utility model, the blind call transfer SE can directly transmit the transfer request to the party to be transferred, so as to reduce the signaling path and save the unnecessary expenses used for the user's blind call transfer service.

Description

technical field [0001] The present invention relates to multimedia services in the communication field, and more particularly relates to session blind transfer services and conference services in the IP multimedia subsystem. Background technique [0002] Internet Protocol (IP, Internet Protocol) Multimedia Subsystem (IMS, IP MultimediaCore Network Subsystem) is an IP-based network architecture proposed by the Third Generation Partnership Project (3GPP, 3rd Generation Partnership Project), which builds an open The flexible service environment supports multimedia applications and can provide users with rich multimedia services. [0003] In the IMS service system, the control layer and the service layer are separated, and the control layer does not provide specific services, but only provides necessary functions such as triggering, routing, and charging to the service layer. The service triggering and control function in the control layer is implemented by the call session con...

Problems solved by technology

[0024] Based on the existing implementation scheme, because the blind transfer service SE regards the transfer request belonging to the conference service as belonging to the blind transfer service, so that the subsequent call request of UE-B does not The blind transfer service SE is necessary, which increases the signaling path and unnecessary transfer target modification operations, and also increases the unnecessary blind transfer service cost of UE-A
