Supplementary service implementation method, entity, terminal, electronic equipment and storage medium

Abstract

The embodiment of the invention relates to the technical field of communication, and discloses a supplementary service implementation method, an entity, a terminal, electronic equipment and a storage medium. The supplementary service implementation method is applied to a supplementary service application entity, and comprises the following steps: receiving a call event of a calling terminal reported by a call base entity; issuing a control instruction to the call base entity based on the call event, and indicating a media base entity to establish a first dedicated data channel with the calling terminal and a second dedicated data channel with the supplementary service application entity through the call base entity; and sending and receiving supplementary service information of the calling terminal through the first dedicated data channel and the second dedicated data channel. The dependency of the transmission of the supplementary service information on the SIP signaling is overcome, so that the implementation of the supplementary service is not limited by the SIP signaling and the transmission path thereof any more.

Description

technical field [0001] The embodiments of the present application relate to the technical field of communications, and in particular to a supplementary service implementation method, entity, terminal, electronic device, and storage medium. Background technique [0002] Internet Protocol Multimedia Subsystem (IMS) is a subsystem proposed by the Third Generation Partnership Project (3GPP) to support Internet Protocol multimedia services. It is the development direction of multimedia communication and can Good for communication between people. It adopts the Session Initial Protocol (SIP) system, which makes the communication independent of the access mode, and has the separation of control functions and carrying capacity, call and session separation, application and service separation, business and network separation of various multimedia services. , and various capabilities such as the integration of mobile network and Internet services. With the development of communication...

Problems solved by technology

[0003] However, introducing supplementary services into IMS by extending SIP signaling is prone to the following problems: SIP signaling is transmitted on the same call path, and the extended SIP signaling is easily affected by intermediate network elements in the call path when it is transmitted on the call path. Impact, once the intermediate network element performs special processing on the extension fields in SIP signaling, it will affect the transmission of information; different supplementary services may need to be implemented at different stages of the call, such as before, during, and after a call, but SIP Signaling needs to conform to the rules of signaling interaction during transmission. Therefore, the supplementary services realized by extending SIP signaling can only realize corresponding supplementary services at the specified stage of the call according to the rules. Service information cannot flexibly transmit SIP signaling, and increases the difficulty of implementation; with the increase of various supplementary service information, the information carried by SIP signaling becomes more and more, which affects the efficiency of call establishment
