And an inter working function (IWF) (or unified messaging system) 40 and a host 50 connected via an internet network.

The mobile terminal 10 may include a mobile communication terminal, a personal digital assistant (PDA) or a notebook that can transmit and receive information by connecting to a mobile communication terminal.

Referring to FIG. 2, a conventional packet data service method configured as described above, a caller connects the mobile terminal 10 to a terminal such as a computer and transmits a call to the telephone number of the receiving terminal (S20).

The outgoing call is transmitted to the exchange 30 through the base station 20, and the exchange determines whether the received call is a packet call (S21), and the determination result is not a packet call, and performs an operation for a call. And, if the packet call to establish a traffic path with the network interlocking device 40 (S22), the network interlocking device 40 assigns the IP of the connected terminal (S24), the mobile terminal and the network interlocking device ( 40) performs a process of setting a logical link setting protocol (S25).

When the logical link setting protocol is set and the calling party executes an application program (S26), data of a network layer or higher is transmitted to the network interlocking device 40 via the switch 30 (S27). The data of the network layer or more includes path information of the network layer, final error checking information of the transport layer, code conversion information or synchronization information of other higher layers, and the like.

The transmitted data is routed to the Internet network by the network interlocking device 40 (S28), and is connected to the host 50, the sender connected to the Internet host 50 in the same manner as the file transmission and reception, It is possible to perform network operations, such as email, the Internet (S29).

In addition to the above methods, it is possible to perform packet data service by connecting to a web server or other host connected to the Internet using PDA. In this case, the PDA supports both the step of setting the logical link setting protocol by the network interlocking device in step S25 and executing a protocol and a network application program over a network layer.

In addition to the method of using the network interlocking device 50, a voice call may be sent by using the UMS to access the UMS, and then the voice mail may be sent or the incoming mail may be checked.

However, in order to use the conventional packet data service, the caller's terminal was able to connect to a host of the Internet network in the same manner as above and use a mobile terminal's chat or game service only through a specific application program. Since the stored data are not managed in a file format, in order to exchange data with each other, there is no choice but to download and use the data offline on a computer through a special application program.

In addition, by building a van it was not possible to network work between a plurality of terminals.

In order to solve the above problems, the present invention forms a wireless network consisting of a plurality of mobile terminals, using a packet data service to connect to all the terminals in the network, share files between all mobile terminals in the network, The purpose of the present invention is to provide a virtual private network implementation method of a mobile terminal group that enables network operations.
