Abstract

A wireless communication device supporting at least non-connection communication and a control method therefore are disclosed. It is determined whether a request for non-connection communication occurs and, when the communication request occurs during an online mode, the online mode is changed to an offline mode in response to occurrence of the communication request, and then the non-connection communication is started. When the communication request occurs, the Auto-Find-IAS function is disabled to prevent undesired connection to another device.

Claims

1. A control method for a wireless communication device which has an online mode and an offline mode and supports at least non-connection communication which is allowed in the offline mode, wherein the communication device is a mobile communication station having an infrared communication function, the method comprising the steps of:

a) determining whether a first request for the non-connection communication occurs;

b) when the first request occurs during the online mode, interrupting the online mode and changing to the offline mode immediately in response to the first request and when the first request occurs during connection communication with another wireless communication device, disconnecting the connection communication; and

c) starting the non-connection communication in response to the first request.

2. A method according to claim 1, wherein the non-connection communication conforms to IrMC Infrared Mobile Communications standard.

3. A control method for a wireless communication device which has an online mode and an offline mode and supports at least non-connection communication which is allowed in the offline mode, wherein the communication device is a mobile communication station having an infrared communication function, the method comprising the steps of:

a) determining whether a first request for the non-connection communication occurs;

b) when the first request occurs, immediately setting a communication mode to a no-response mode in response to the first request, wherein the no-response mode provides no response to a request received from another communication device;

c) when the first request occurs during the online mode, changing the online mode to the offline mode in response to the first request; and

d) starting the non-connection communication.

4. A method according to claim 3, wherein the no-response mode is set by disabling an Auto-Find-IAS information assess service function conforming to IrMC Infrared Mobile Communications standard.

5. A wireless mobile communication station having an infrared communication function and an online mode and an offline mode and supporting at least non-connection communication which is allowed in the offline mode, comprising:

a transceiver for transmitting and receiving data to and from another wireless communication apparatus;

an input device for inputting an instruction; and

a communication controller controlling such that when a first request for non-connection communication occurs during the online mode, the online mode is interrupted and immediately changed to the offline mode in response to the first request,

wherein the communication controller controls such that when the first request occurs during connection communication with another wireless communication device, the connection communication is disconnected and changed to the offline mode in response to the first request.

6. A wireless communication apparatus according to claim 5, wherein the communication controller further controls such that when the first request occurs, a communication mode is set to a no-response mode in response to the first request, wherein the no-response mode provides no response to a request received from another communication device.

7. A wireless communication apparatus having an online mode and an offline mode and supporting at least non-connection communication which is allowed in the offline mode, wherein the communication apparatus is a mobile communication station having an infrared communication function, comprising;

a transceiver for transmitting and receiving data to and from another wireless communication apparatus;

an input device for inputting an instruction; and

a communication controller controlling such that when a first request for non-connection communication occurs during the online mode, the online mode is changed to the offline mode in response to the first request,

wherein the communication controller further controls such that when the first request occurs, a communication mode is set to a no-response mode in response to the first request, wherein the no-response mode provides no response to a request received from another communication device,

wherein the no-response mode is set by disabling an Auto-Find-IAS information assess service function conforming to IrMC Infrared Mobile communications standard.
