    • PURPOSE: A system and method based on passive optical subscriber network for providing a handover between optical subscriber network terminals are provided to quickly find an optical subscriber terminal device which is connected to a terminal by moving the optical subscriber terminal device through a mobile terminal. CONSTITUTION: A passive optical subscriber network base system(100) comprises an optical line terminator(101) and an optical subscriber terminal device. The passive optical subscriber network base system comprises the optical line terminator and one or more optical subscriber terminal devices(102,103). The optical subscriber terminal device transmits a Wi-Fi location updating alarm message to the optical line terminator while being connected a mobile terminal(104). The optical line terminator updates a look up table in response to the received Wi-Fi location updating alarm message.
