Description

Packet Data Service Apparatus and Method for Mobile Phone to Mobile Phone}

The present invention relates to an apparatus and method for packet data service between mobile terminals, and more particularly, to an apparatus and method for one-to-one packet data service of a mobile terminal.

Packet data service using a mobile terminal sends a packet call from a mobile terminal to connect to a host connected to the Internet network to send or receive a file, or uses another mobile phone subscriber connected to the host and an application program installed on the Internet host. It is structured to chat or play games.

The structure and method of a packet data service using a conventional mobile terminal are the same as those of FIGS. 1 and 2, FIG. 1 is a block diagram illustrating a structure of a conventional packet data service, and FIG. 2 is a packet data using a conventional mobile terminal. It is a flowchart showing the operation sequence according to the service method.

Referring to FIG. 1, in order to use a packet data service, a mobile terminal 10 for transmitting and receiving packet data, a network unit 20 for establishing a traffic path with the mobile terminal 10, and a connection with the network unit are provided. It is configured to include an inter working function (IWF) (or unified messaging system (UMS)) 30, and a host 40 connected through an internet network.

The mobile terminal 10 includes a mobile communication terminal 13, a personal digital assistant (PDA) 12, or a notebook and mobile communication terminal 11 to which a notebook and a mobile communication terminal are connected.

The network unit 20 also includes a base station 21 and a mobile switching center (MSC) 22.

Referring to Fig. 2, the conventional packet data service method configured as described above, the caller sends a call to the telephone number of the receiver using the mobile terminal 13 (S20).

The outgoing call is transmitted to the switch 22 through the base station 21, and the switch 22 determines whether the received call is a packet call (S21). In the case of a packet call, a traffic path is established with the network interlocking device 30 (S22), and the network interlocking device 30 assigns an IP of the connected terminal (S24), and the mobile terminal and the network. A process of setting a logical link setting protocol between the companion devices 30 is performed (S25).

After the logical link is established by the logical link setting protocol, when the calling party executes an application program (S26), data over a network layer is transmitted to the network interlocking device 30 via the switch 22 (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 30 (S28), and is connected to the host 40, the sender connected to the Internet host 40 in the same manner as the file transmission and reception, Operations such as email and the Internet may be performed (S29).

The above method can perform all the functions of performing an Internet service by connecting a computer to a wired Internet network.

In addition to the above method, the PDA 12 may be connected to a web server or other host connected to the Internet network to perform packet data service. In this case, the PDA 12 supports both the mobile terminal 13 and the network interlocking device 30 performing a logical link setting protocol 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 30, a voice call may be sent by using the UMS to access the UMS, and then a voice mail may be sent or an incoming mail may be checked.

However, in order to use the conventional packet data service, the calling mobile terminal connected to a host of the Internet network in the same manner as described above, was able to use a service such as chatting or playing games with other users only through a specific application program. Since the data stored in the file are not managed in a file format, in order to exchange data with each other, there is no choice but to download and use it offline from a computer through a special application program.

In order to solve the above problems, the present invention allows one-to-one packet calls to be connected between terminals, and provides one-to-one packet data service for providing more free packet data services such as sharing or copying data between terminals. An object of the present invention is to provide a packet data service apparatus and method.

2 is a flowchart illustrating an operation procedure according to a method of a packet data service using a conventional mobile terminal.

3 is a block diagram showing the structure of a one-to-one packet data service apparatus of a mobile terminal according to an embodiment of the present invention.
