Game establishing method between mobile communication terminals

The present invention relates to a method of game communication between mobile communication terminals, and more particularly, when a game is played between mobile communication terminals, a protocol (TCP / IP) such as an originating mobile communication terminal is automatically set by the receiving mobile communication terminal. The present invention relates to a game communication method between mobile communication terminals.

1 is a block diagram of a wireless data service network of a general mobile communication system.

As shown in FIG. 1, a mobile communication terminal 10 for transmitting and receiving data to and from the base station wirelessly, a base station 20 for transmitting and receiving data to and from the mobile communication terminal 10 wirelessly, and the base station 20 The control station 30 which controls data transmission and reception is connected to the mobile communication exchanger 40 and the mobile communication exchanger 40, which are exchange stations for exchanging data between arbitrary terminals via the control station 30, and perform data communication. CDMA network 50 which is a communication network for communication, public telephone network 60 connected to the mobile communication switch 40 and performing analog voice telephone service, and data through the IS-658L interface with the mobile communication switch 40. An Interworking Function Unit (IWF) 70 for interfacing the network, a Packet Switched & Public Data Network (PSPDN) 80 for connecting to the interworking unit 70 to service data and voice, and an internet network. (90) And connected to the Internet network (90) comprises a game server 100 that provides game.

In the drawings, Um denotes an interface between the mobile terminal and the base station, A denotes an interface between the control station and the mobile communication exchange period, Ai denotes an interface between the mobile communication exchange and the PSTN, E denotes an interface between the mobile communication exchange and the CDMA network, and Pi Represents an interface between the IWF and the PSPDN, respectively, and 100 represents a home location register.

The mobile communication terminal 10 of the general mobile communication system configured as described above transmits and receives data and voice to the base station 20 through a wireless interface (transmission rate of 8 Kbps in the wireless section) according to the IS-95 standard.

In addition, the base station 20 transmits and receives information of the mobile communication terminal 10 with the control station 30 through a wired interface, and the voice and the mobile communication terminal 10 through a wireless interface according to the IS-95 standard. Send and receive data wirelessly. That is, the base station 20 is responsible for the call processing function, radio signal transmission and reception function, radio resource management function, time information management function between the mobile station and the base station, error detection and statistical information collection and reporting function, packet routing function, power control function. do.

And the control station 30 is located between the base station 20 and the mobile communication switch 40, and the data communication with the base station 20 in the form of a voice packet via a wire, the operator with the mobile communication switch 40 It features a man-machine interface for registration and a Global Positioning System (GPS) reception. That is, the control station 30 has a call connection function between the mobile terminal and the mobile terminal period, a handoff function when the mobile terminal moves between sectors in the base station or from the service area of the current base station to another service area, and a wired channel with the base station. Communication of voice and data information in the form of packets, interfacing voice and signal with mobile exchanges, voice compression and restoration (transcoding), man-machine interface for operator registration, base station operation and configuration management, and control station maintenance And fault management.

Next, the mobile communication switch 40 performs an interworking interface between the mobile communication exchange and the mobile communication exchange period, fixed subscribers other than the mobile communication exchange, and other mobile communication elements, and other networks such as ISDN and PSDN. In addition, the mobile communication switch including the functions of the cellular gateway switching system is a multi-processor structure that distributes functions and loads, and has a distributed control structure that is a two-stage hierarchical structure of a main processor and a lower processor.

Meanwhile, in recent years, an IWF unit 70 for data wireless service has been newly added to the general wireless data service network structure.

Therefore, an interface device is required for the mobile communication switch 40 and the IWF unit 70 to smoothly perform mutual voice and data.

The interface between the mobile communication switch 40 and the IWF unit 70 performs an interface based on an interface protocol defined in IS-658.

In particular, the user having the Internet-enabled mobile communication terminal 10 can access the game server 100 through the IWF unit 70, and select the game menu to play the game.

Therefore, several people on a network play a game using a mobile communication terminal.

However, when trying to play a game using a mobile communication terminal on the network, there is a problem that takes a long time by setting the TCP / IP protocol through the IWF unit.

Therefore, the present invention has been proposed to solve the above-mentioned problems according to the prior art, and an object of the present invention, when the mobile communication terminal to play a network game, the calling party mobile communication terminal is directly receiving side mobile communication The present invention provides a game communication method between mobile communication terminals that can play a game with an opponent by dialing the terminal.

Characteristic of the game communication method between mobile communication terminals according to the present invention for achieving the above object,

In the game communication method between mobile communication terminals.

If the receiving mobile communication terminal is in a game waiting state, determining whether the receiving mobile communication terminal receives a game signal from the calling mobile communication terminal;

Hereinafter, a preferred embodiment of a game communication method between mobile communication terminals according to the present invention will be described with reference to the accompanying drawings.

2 is a flowchart illustrating a game communication method between mobile communication terminals according to the present invention.

As shown in FIG. 2, when the calling mobile terminal makes a call to the receiving mobile terminal, when the receiving mobile terminal is in the game standby mode, the receiving mobile terminal is disconnected from the calling mobile terminal. It is determined whether the game signal "8003" has been received (S101) (S103).

When the receiving mobile communication terminal receives the "8003" game signal from the calling mobile communication terminal, the call state is set to the active state and the TCP state is set to the listener (S105). (S107).

Then, after setting up the Point-to-Point Protocol (PPP), open the file for inter-processor communication so that it can play the game with the calling mobile terminal.

As described above, the present invention is to make a call between the calling mobile communication terminal and the receiving mobile communication terminal so that the mobile communication terminals can play a game, and the receiving mobile communication terminal automatically transmits the calling mobile communication. Since the same protocol as the terminal is set, the game can be played stably.

In addition, since the calling mobile terminal and the receiving mobile terminal can directly connect without passing through the IWF, the connection time can be shortened.
