Abstract: PURPOSE: A network joining method of a communication terminal is provided to connect a subscriber communication terminal to a communication network without receiving and transmitting an ARP(Address Resolution Protocol) request message and an ARP response message. CONSTITUTION: In case a user identifier is inputted, a manager communication terminal searches for identification information from database(S100, S200). The manager communication terminal performs a protocol network join process(S300). A subscriber communication terminal transmits an application network join request message to the manager communication terminal. The manager communication terminal transmits an application network join permission/denial message to the subscriber communication terminal(S400).
