## Abstract

An application execution unit executes an application, and a communication ID acquisition unit acquires a communication identifier set for the application. When a packet generation unit generates a packet including a communication identifier and data, a transmission unit transmits the packet in an IBSS identified by an SSID stored in a SSID storing unit. When a reception unit receives a packet from another terminal device, a determination unit determines whether the communication identifier acquired by the communication ID acquisition unit matches a communication identifier included in the received packet. When the determination unit determines that the acquired communication identifier matches the communication identifier included in the received packet, a data supply unit provides data included in the received packet to the application.

## Claims

### Claim 1

A terminal device configured to be connected to a wireless network identified by a predetermined network identifier, comprising:
an execution unit configured to execute an application;
an acquisition unit configured to acquire a communication identifier set for the application;
a transmission unit configured to transmit a packet including a communication identifier and data;
a reception unit configured to receive a packet from another terminal device; and
a determination unit configured to determine whether the communication identifier acquired by the acquisition unit matches a communication identifier included in the received packet.

### Claim 2 (depends on 1)

The terminal device according to claim 1, further comprising:
a data supply unit configured to provide data to an application,
wherein, when the determination unit determines that the communication identifier acquired by the acquisition unit matches the communication identifier included in the received packet, the data supply unit provides data included in the received packet to the application.

### Claim 3 (depends on 1)

The terminal device according to claim 1,
wherein the execution unit can execute a plurality of applications, and
wherein the acquisition unit acquires communication identifiers from the plurality of applications when the plurality of applications are being executed.

### Claim 4 (depends on 1)

The terminal device according to claim 1, further comprising:
a recording unit configured to record the communication identifier included in the received packet when the determination unit determines that the communication identifier acquired by the acquisition unit does not match the communication identifier included in the received packet.

### Claim 5 (depends on 4)

The terminal device according to claim 4, further comprising:
a notification unit configured to notify the user of the name of an application corresponding to the communication identifier recorded in the recording unit.

### Claim 6

A data transmission/reception method for transmitting and/or receiving data, comprising:
storing a predetermined network identifier;
acquiring a communication identifier set for an application;
transmitting a packet including a communication identifier and data in a wireless network identified by a predetermined network identifier;
receiving a packet from another terminal device; and
determining whether the acquired communication identifier matches a communication identifier included in the received packet.

### Claim 7

A computer program, for a computer provided in a terminal device, embedded on a non-transitory computer-readable recording medium, comprising:
a module configured to acquire a communication identifier set for an application;
a module configured to transmit a packet including a communication identifier and data in a wireless network identified by a predetermined network identifier;
a module configured to receive a packet from another terminal device; and
a module configured to determine whether the acquired communication identifier matches a communication identifier included in the received packet.
