Embodiment Construction

[0012] See figure 1 Shown is a schematic diagram of the system architecture of the present invention. The present invention includes a process control unit 61, responsible for executing, controlling, and managing service processes, accepting requests from external information systems, and integrating various subunits to complete the service; an identity and logic verification unit 62 , Responsible for the identity verification of the external information system, and the number verification of the caller and the callee; the signal control unit 63 is used to interface with the NGN / IMS network for the transmission and encoding and decoding of SIP signals.

[0013] See figure 2 Shown is a flow chart of the method of the present invention. The steps include: a. The external information system sends a request to establish a call between the two parties to the process control unit of the system of the present invention through the TCP / IP network; b. The process control unit uses the ide...

Abstract

The invention discloses a system and a method for establising both-side communication initiated by exterior. When the external information system emits a requirement for establishing communication between the word sending side and the word receiving side, after the requirement is idenfied by the system, the both-side communication is established through the Session Initiation Protocol (SIP) of the next generation network (NGN) / IP multimedia subsystem (IMS). In the invention, the following is included: I, a process control unit, which executes, controls and manages the service process, receives the requirement of the external information system, and integrates the sub-systems to finish the service; II,identity and logic determination unit, which determines the identity of the external information system, and the number of the word sending side and the word receiving side; and III, a signal control unit, which is connected with NGN-IMS network, receives and decodes the SIP signals, thereby the both-side communication service initiated by exterior can be provided.

Description

Technical field [0001] The present invention relates to the field of communication, in particular to a system and method for establishing a call between two parties initiated by the outside. Background technique [0002] The method of establishing a two-party call initiated by an external party was mostly through a web page click to establish a two-party call. The previous technology is limited to the traditional fixed or mobile switching network. It uses the server bridging method. The server first speaks to the caller, establishes the server and the caller, and then the server speaks to the receiver to establish a server The server communicates with the callee, and finally the server exchanges the voice content of the caller and the callee in a bridging manner to achieve the purpose of the call between the two parties. [0003] Among the existing methods for establishing a two-party call initiated by an external party, the Taiwan Patent Application (I324010) combines a webpage r...
