SYSTEM AND METHOD FOR PROVIDING SERVICE TO END TERMINAL THAT USES AUTHENTICATION INFORMATION OF ANOTHER MOBILE COMMUNICATION TERMINAL, SERVICE SERVER, MOBILE COMMUNICATION TERMINAL, END TERMINAL, AND STORAGE MEDIUM

摘要

The present invention relates to a system and a method for providing a service to an end terminal that uses authentication information of another mobile communication terminal, to a service server, to a mobile communication terminal, to an end terminal, and to a storage medium. The present invention enables the end terminal to use a service even when the authentication information of the end terminal is not the authentication information of the mobile communication terminal currently connected to the end terminal. The system of the present invention comprises an end terminal, a second mobile communication terminal, and a service server. The end terminal is connected to a first mobile communication terminal and to the second mobile communication terminal through a local area network, and connected to the service server through the second mobile communication terminal, and uses the service by using the authentication information of the first mobile communication terminal. The second mobile communication terminal is connected to the end terminal through the local area network, and connected to the service server through a mobile communication network, and connects the end terminal that uses the authentication information of the first mobile communication terminal to the service server. The service server is connected to the first mobile communication terminal and to the second mobile communication terminal through the mobile communication network, and performs authentication to enable the end terminal that uses the authentication information of the first mobile communication terminal to use the service through the second mobile communication terminal.
