Abstract:
A system for accessing a node of a private network includes an assigning portion for assigning external port values to respective network nodes based on information collected from the network nodes of the private network, and storing the assigned external port values; an exchanging portion for exchanging the external port values of the respective network nodes of private networks; and an address converting portion for converting the external port values into corresponding private IP addresses and internal port values when a network node of one private network accesses another network node of another private network by using the external port values of another network node of another private network. Accordingly, a network node of a private network without a global IP address becomes accessible.
Abstract:
A global positioning system using Bluetooth technology, including: a first Bluetooth master that receives satellite orbit information; a Bluetooth slave that communicates with the first Bluetooth master in a Bluetooth protocol; and a second Bluetooth master that transmits an inquiry code for communication with the Bluetooth slave in the Bluetooth protocol. The second Bluetooth master provides positioning information by requesting the satellite orbit information from the first Bluetooth master through the Bluetooth slave and transmitting the satellite orbit information to the second Bluetooth master through the Bluetooth slave.

Abstract:
A shooting game method and an apparatus for a mobile terminal device using local positioning communication to run a shooting game by local positioning communication based on positions of the mobile terminal device and a neighboring mobile terminal device. Accordingly, improving the user convenience implementing an intelligent shooting game using a position recognizing function of the mobile terminal device, and also, instead of a stand-alone game, twosome or more games can be implemented.
