Title: The distributed internet phone system
IPC: H04M3/42
Filed: 2020-04-29
Abstract: Currently, many companies, such as telecommunication companies, SNS service providers, and the like, are providing Internet phone services due to the development and speed of the Internet and the Internet phone services using smartphone applications are also being provided due to spread of smartphones. However, since each service provider provides services through their own servers, the service provider's burden on facility investment, such as server expansion and the like, increases significantly due to increase in subscribers and call quality deteriorates, such as delays, dropouts and the like, as traffic increases. The present invention relates to a distributed Internet phone system in which a server is constructed by group unit, such as a home, a company, an institution, a group, a region, and the like, instead of a server of a specific company to enable members to make a call therebetween and enable members to make a call between the members belonging to different groups by receiving information about the other party's server from a central server and connecting both group servers. According to the present invention, since a server is constructed by group unit to provide a service between group members with a high call volume, a service can be easily expanded. In addition, since services between members of different groups are provided by using a plurality of servers constructed for each group rather than a central server, burden on facility investment is dispersed even if the number of users increases, thereby facilitating facility investment and providing good call quality.
