Video telephone system and video conversation method based on home SIP server

Abstract

The invention provides a video telephone system based on a home SIP (Session Initiation Protocol) server, comprising an SIP server used for providing a home telephone account number registering and basic call function, home B2BUA servers used for providing home telephone protocol transmission and distribution, and session transfer, and mobile terminals used for displaying and used as conversation initiators. The mobile terminals are in connection with the B2BUA servers, and send the registration Information of a first user to a first B2BUA server; the first B2BUA server detects and preserves the registration Information of a mobile terminal, and sends the registration Information to the SIP server after successful registration; the SIP server receives the registration Information of a second user; the second user called by the first user sends a call request to the SIP server; the SIP server transfers the mobile terminal of the second user through a second B2BUA server to establish conversation connection. The video telephone system realizes pressure decomposition of the SIP server through B2BUA; each B2BUA server is a miniature SIP server, and can realize the basic conversation function of a domestic consumer.
