Method for providing open market service using bluetooth mobile phone

摘要

PURPOSE: A method for providing open market service using a Bluetooth mobile phone is provided to form a local wireless communication environment in order to provide an open market service. CONSTITUTION: If other Bluetooth terminal exists in a local wireless communication radius, a Bluetooth wireless network is formed in Bluetooth terminals(S520~S540). Among the connected Bluetooth terminals, a database is synchronized(S550~S580). After the predetermined time passes, the Bluetooth wireless network is deregulated(S590). In the synchronization of database, a master node merges with data of the slave node among Bluetooth terminals. The master node transmits data to the slave node.
