Description
Technical Field
The invention relates to the technical field of communication and information, in particular to an intercom system based on a cloud platform.
Background
At present, the speech intercom systems in the market generally comprise front-end audio and video acquisition hardware and a server; the function is summarized as follows: audio and video talkback within a fixed range; the server provides audio and video recording and on-demand transmission functions.
This form of voice intercom system mainly has the following problems: 1) the price is expensive, and hundreds of thousands are often used; 2) the implementation process is long; 3) compatibility is poor, and generally only internal products of the same brand are compatible; 4) the application range is very limited; 5) the repeatability and practicability are poor.
Modern society is demanding high efficiency more and more, and the collection of real-time information, processing requirement are higher and more, must require to incorporate more swift efficient equipment for use. Such as: whether the mobile phone, the fixed phone, the notebook computer, the ipad, the satellite mobile phone, the conference terminal and other equipment are connected to the voice intercom system or not can be judged, so that real-time conversation and even multi-point real-time conversation are realized; and the temporary meeting is held with the full-range recording function and the like.
SIP (Session Initiation Protocol) is a multimedia communication Protocol established by IETF (internet engineering Task Force). It is a text-based application-layer control protocol for creating, modifying and releasing sessions of one or more participants. The present invention is widely applied to CS (Circuit Switched), NGN (Next Generation Network) and IMS (IP multimedia Subsystem) networks, and can support and apply multimedia services such as voice, video, data, and the like, and also can apply to special services such as Presence, Instant Message, and the like. It can be said that there is an existence of the SIP protocol where there is an IP network. The method of registering devices through the SIP protocol has been introduced in many applications in the field, such as "design and implementation of a voice intercom system based on the SIP protocol".
Public Switched Telephone Network (PSTN), a Telephone Network commonly used in our daily life. As is well known, the PSTN is a circuit-switched network based on analog technology. At present, the public switched telephone network has been technically completely digitized except for the last connection between the user and the local exchange. In connection with the internet, the PSTN provides a significant portion of the long distance infrastructure of the internet. Internet Service Providers (ISPs) pay equipment owners fees in order to use the long distance infrastructure of the PSTN and to share circuits between numerous users through the exchange of information. So that the internet user only needs to pay the internet service provider. The public switched telephone network is a circuit switched service based on standard telephone lines, which is used as a connection method for connecting remote endpoints. Typical applications are connections between remote endpoints and local LANs and remote user dial-up. The application strategy of soft switch in the evolution of PSTN network published in Zhongxing communication technology in 2002 introduced the soft switch mode of PSTN network.
