In particular, the first mobile phone 100A and the second mobile phone 100A can obtain the room name simply by calling the second mobile phone 100B from the first mobile phone 100A. The trouble that the user of the telephone 100B performs before starting the P2P communication can be greatly reduced.
- each communication device generates a room name that does not overlap with the room name of another chat room. There is no need to think of a room name that does not overlap with the name.
- a mail address is identification information that can specify each communication device, and therefore includes a relatively large number of characters. Therefore, it is troublesome for the user to input a room name for each chart room including the first mail address and the second mail address. The network system 1 according to the present embodiment can save such user trouble.

When the TEL button 110A is operated (YES in step S214), the processor 106 stops the first notification unit 111 (step S216) and turns off the TEL LED 112A (step S218).
- the processor 106 shifts to the incoming call response mode, that is, shifts to the on-hook mode (step S220), and then performs call control (step S222).
- the processor 106 determines whether or not the TEL button 110A has been operated (whether or not a disconnection signal has been received) (step S224).
- TEL button 110A is operated (YES in step S224)
- processor 106 ends the TEL incoming call process and repeats the process from step S052. If the TEL button 110A is not operated and no disconnection signal is received (NO in step S224), the processor 106 repeats the processing from step S222.

- processor 106 changes first notification unit 111. It operates (step S302), and the P2P LED 112B blinks (step S304).
- the processor 106 inquires of the matching server 400 whether or not there is a chat room having the RMNM chat room name via the communication interface 101 (step S306). In other words, the processor 106 determines whether or not the chat room having the RMNM chat room name of the matching server 400 has already been closed.
- step S306 If there is no chat room having the RMNM chat room name (NO in step S306), the processor 106 stops the first notification unit 111 (step S308). The processor 106 turns on the P2P LED 112B (step S310), and repeats the processing from S052. At this time, the processor 106 registers the registration in the memory 103.

Processor 106 repeats the processing from step S306 when an instruction to perform P2P communication is not input (NO in step S312).
- processor 106 When an instruction to perform P2P communication is input via input device 110, that is, when the user inputs an instruction to enter the chat room (in the case of YES in step S312), processor 106 performs the first notification. After stopping the unit 111 (step S314), the P2P LED 112B is turned off (step S316).
- the processor 106 enters the chat room of the matching server 400 via the communication interface 101 (step S318). That is, the processor 106 transmits a room entry request to the matching server 400 via the communication interface 101, and acquires the other party's IP address in the P2P communication from the matching server 400.
- the processor 106 stores the other party's IP address in the HIS_IPADR (step S320), and controls the P2P communication (step S322).
- the processor 106 determines whether or not the P2P button has been operated by the user via the input device 110 (or whether or not a communication end notification has been received from the partner communication device in P2P communication) (step S324). That is, the processor 106 determines whether or not a command for interrupting the P2P communication has been received from the user. If the P2P button is not operated (NO in step S324), processor 106 repeats the processing from step S322. When the P2P button is operated (YES in step S324), processor 106 releases the connection to Internet network 500 (step S326). That is, the processor 106 ends the P2P call processing and then repeats the processing from step S056.
- FIG. 18 is a flowchart showing a processing procedure of response processing in matching server 400 according to the present embodiment.
- CPU 405 of matching server 400 waits for a message from first mobile phone 100A via server communication interface 409 (step S902).
- CPU 405 determines whether the message is a generation request for generating a chat room (step S904).
- step S904 If the message is a generation request for generating a chat room (YES in step S904), CPU 406 determines whether or not the room name included in the generation request exists in room management table 406A (step S904). S906). If the room name exists in room management table 406A (YES in step S906), CPU 406 notifies that room generation has failed (step S932), and repeats the processing from step S902.
- the CPU 406 If the room name does not exist in the room management table 406A (NO in step S906), the CPU 406 generates a room with the room name (step S908). That is, the CPU 406 stores the room name and the caller IP address included in the generation request in association with each other in the room management table 406A. The CPU 406 notifies the caller's IP address that the room has been successfully generated (step S910).
- the CPU 406 determines whether the message is a search request for searching for a room name (step S912).
- step S912 If the message is a search request for searching for a chat room (YES in step S912), it is determined whether or not the room name included in the search request exists in room management table 406A (step S914). . If the room name exists in room management table 406A (YES in step S914), CPU 406 notifies the requesting IP address that the room has been found (step S910), and performs the processing from step S902. repeat.

- the CPU 406 determines whether the message is a deletion request for deleting a chat room (step S916).
- CPU 406 associates the request source IP address with the room name included in the deletion request, and manages room management table 406A. It is determined whether or not it is stored in (step S918). That is, CPU 406 determines whether or not the requesting communication device is a communication device that has already entered the chat room.
- CPU 406 deletes the chat room with the room name ( Step S920). The CPU 406 notifies the requesting IP address that the chat room has been successfully deleted (step S910), and repeats the processing from step S902.
- step S928 When the IP address of the request source is stored in the room management table 406A in association with the room name included in the deletion request (NO in step S918), the CPU 406 displays the chat room IP address as the request source IP address. Notifying that the deletion has failed (step S932), the processing from step S902 is repeated.
- step S916 determines whether the message is a request for entering the chat room (step S922).
- Step S922 If the message is a room entry request for entering the chat room (YES in step S922), CPU 406 determines whether the room name included in the room entry request is stored in room management table 406A. (Step S924). When the room name included in the room entry request is stored in room management table 406A (YES in step S924), CPU 406 registers the IP address of the request source in room management table 406A in association with the room name. (Step S926).

- CPU406 repeats the process from step S902.
- the message is not an entry request for entering a chat room (NO in step S922), and the room name included in the entry request is not stored in room management table 406A (in step S924). If NO, CPU 406 transmits an error message to the requesting IP address (step S932), and repeats the processing from step S902.
