Providing evolution data only (EV-DO) service in network interfacing wireless public network and wired/wireless private network

A method comprising:

• arranging a network interfacing a wireless public network and a wired/wireless private network;
• setting up, by an arbitrary terminal, an identifier indicating which of the public and private networks is to transmit an Evolution Data Only (EV-DO) service;
• storing the identifier set up by the arbitrary terminal in a private network data base;
• retrieving the identifier received from the arbitrary terminal to request the EV-DO service via a corresponding network based on the retrieved identifier;
• and
• wherein storing the identifier set up by the arbitrary terminal in a private network database comprises referring to a field for a private network route that is set up for each entry of a private network EV-DO service setup table in a database within a private network control station, wherein an EV-DO service request signal received via a base station is transmitted to a private network control station along with an identifier of a corresponding user terminal.

A method comprising:

• arranging a network interfacing a wireless public network and a wired/wireless private network;
• setting up, by an arbitrary terminal, an identifier indicating which of the public and private networks is to transmit an Evolution Data Only (EV-DO) service;
• storing the identifier set up by the arbitrary terminal in a private network data base;
• retrieving the identifier received from the arbitrary terminal to request the EV-DO service via a corresponding network based on the retrieved identifier;
• and
• releasing a function of setting up the EV-DO service via the private network;
• wherein retrieving the stored identifier set up by the arbitrary user terminal from the private network database and providing the EV-DO service comprises the arbitrary user terminal inputting and setting up a specified number including a characteristic code including a private network access code plus a function access code plus a private network EV-DO service setup and release function code using a keypad of a wireless terminal.

A system comprising:

• at least one base station adapted to receive a call from an arbitrary wireless Evolution Data Only (EV-DO) terminal and to transmit a call to the arbitrary wireless terminal;
• a public network adapted to control the call upon transmitting and receiving via the public network an EV-DO call transmitted and received via the at least one base station;
• a private network including a route determining unit adapted to determine, based on an identifier of a transmission-side terminal included in the EV-DO call received by the base station, which of the private and public networks is to send the EV-DO call, and to transmit the call via a corresponding network;
• and
• a private network dedicated private EV-DO system adapted to directly send the EV-DO call via the private network rather than the public network, upon the private network determining that the currently received EV-DO call is a private network call;
• wherein the private network comprises:
• a database having a table structure including a transmission-side terminal identifier field and a field indicating an EV-DO service route;
• the route determining unit adapted to determine the call service route with respect to a calling identifier by referring to a database that stores the calling identifier of the call received via the base station, and to transmit the call to a corresponding one of the private network and the public network;
• and
• a private network control module adapted to transmit the call to the private EV-DO system upon a call received via a data routing software module being a private network EV-DO call and, writing the input to the database upon receiving an input regarding a setup using the private network and the public network from the transmission-side terminal;
• wherein the EV-DO service route field of the database includes an initial setup, the initial setup being set for a public network upon the EV-DO service route not being set by a user.

A system comprising:

• a terminal adapted to transmit a message along with identifier information upon transmitting an Evolution Data Only (EV-DO) call;
• at least one base station adapted to receive an EV-DO call from the terminal and to transmit the EV-DO call to an arbitrary wireless terminal;
• a private network adapted to determine, based on the identifier information included in the EV-DO call received from the terminal, which of the private network and a public network is to transmit the EV-DO call;
• the public network adapted to control data control upon transmitting and receiving the EV-DO call transmitted and received via the base station;
• and
• a private network dedicated private EV-DO system adapted to directly provide the EV-DO service via the private network rather than the public network upon the private network determining that the currently received EV-DO call is a private network EV-DO call;
• wherein the terminal is adapted to display the network via which the EV-DO service is being transmitted, a remaining number of times of transmission and a remaining time on a display.
