METHOD FOR IPV6 MULTICAST BASED N-TO-N GROUP TUTORING SYSTEM IN THE HOME NETWORK

摘要

A method for providing a multi-party group tutoring service using an IPv6 multicast function in a home network is provided to manage and utilize multicast communication by using an HS(Home Server) in providing a multi-party group tutoring service in a home network, and easily solve a problem of IPv6 multicast forwarding. A user at home determines multicast communication transmission/reception for a group tutoring service(401). When a session corresponding to transmission of multicast communication is established, a DB(Database) server is executed, a group information registration message is transferred to an HS, the group information registration message is registered in an RP(Rendezvous Point) and the fact is confirmed, preparation of communication is completed by transmitting group subscription information, and a group tutoring service starts(402,404,405,406,407,408,409). In case of receiving multicast communication, a multicast is received, group information, a group subscription message, is transferred to the HS, the group information is transferred to the RP to register reception information, the registration is confirmed, the group subscription information is transmitted to complete preparation of communication, and a group tutoring service starts(403,410,411,412,413,408,409).
