## Abstract

Provided is a communication apparatus for preventing a shortage of wireless LAN resources. A communication-control unit controls wireless communication via an access point and P2P type communication (P2P communication); a connection-information-managing unit manages connection information of the access point, and request-having information that indicates there is a connection request from a portable terminal using the wireless communication; and a system-control unit causes the connection-information-managing unit to change the connection information when the connection-information-managing unit is managing the request-having information. By changing the connection information of the access point when there is a connection request from a portable terminal using wireless communication, automatic connection that is executed after cutting communication is selected on the portable terminal side is disabled so that unintended connection requests are not received from the portable terminal side.

## Claims

### Claim 1

A communication apparatus, comprising:
a communication-control unit that controls wireless communication via an access point and P2P type communication;
a connection-information-managing unit that, when the communication apparatus operates as a group owner that corresponds to the access point, manages a first connection information of the access point, and request-having information that indicates there is a connection request from a client using the wireless communication; and
a system-control unit that, when there is a connection request from a client by the wireless communication, causes the connection-information-management unit to manage the request-having information, compares a second connection information transmitted from the client with the first connection information, and establishes a connection with the client by the wireless communication when both match; wherein
the system-control unit
(1) causes the communication-control unit to block the communication when the connection by the wireless communication and/or the P2P type communication is lost,
(2) in the case of (1), causes the connection-information-managing unit to change the first connecting information when the connection-information-managing unit is managing the request-having information, and
(3) when the first connecting information is changed, causes deletion of the request-having information and causes the communication-control unit to stop the block of the communication.

### Claim 2 (depends on 1)

The communication apparatus according to claim 1, comprising
a panel unit; wherein
the system-control unit causes the communication-control unit to receive a connection request from the client using the wireless communication within a set amount of time when activation by the group owner via the panel unit is instructed, and when communication using the wireless communication ends, or when there is no connection request from the client using the wireless communication within the set amount of time, causes activation by the group owner to end.

### Claim 3

A non-transitory computer-readable recording medium for storing a communication program that can be executed by a computer of a communication apparatus; and the communication program causes the computer to operate as:
a communication-control unit that controls wireless communication via an access point and P2P type communication;
a connection-information-managing unit that, when the communication apparatus operates as a group owner that corresponds to the access point, manages a first connection information of the access point, and request-having information that indicates there is a connection request from a client using the wireless communication; and
a system-control unit that, when there is a connection request from a client by the wireless communication, causes the connection-information-management unit to manage the request-having information, compares a second connection information transmitted from the client with the first connection information, and establishes a connection with the client by the wireless communication when both match; wherein
the system-control unit
(1) causes the communication-control unit to block the communication when the connection by the wireless communication and/or the P2P type communication is lost,
(2) in the case of (1), causes the connection-information-managing unit to change the first connecting information when the connection-information-managing unit is managing the request-having information, and
(3) when the first connecting information is changed, causes deletion of the request-having information and causes the communication-control unit to stop the block of the communication.
