Wireless communication apparatus

An information processing apparatus has a short-distance wireless communication unit which communicates with external equipment, an input unit, a timer, and a control unit. The input unit generates a press event in response to depression of the input unit and a release event in response to release the input unit from the depression. The timer measures an elapsed time. The control unit starts the timer in response to reception of the press event, transmits a press command or a release command to the external equipment in response to the reception of the press event or the release event, and transmits the release command to the external equipment when the control unit detects that the elapsed time reaches a specific time and no event is received from the input unit.

Information processing apparatus

A controller of a mobile communication apparatus, such as a cellular phone, that detects operator information based on a radio signal transmitted from a base station and checks whether the operator information has changed while maintaining the same roaming status information. When the controller detects that the operator information changed, the controller transmits one of the same roaming status information and service status information to an external device which is connected via a short-range communication link.

Communicating operator information to an external device

A radio communication apparatus executes communication by establishing a communication link according to a security level with other device. The radio communication apparatus sets a security level according to a type of service, and discriminates whether the security level is necessary for the communication with the other device. If the security level is necessary, the communication link according to the security level is established. If the security level is not necessary, security level is lowered and the communication link according to the lowered security level is established.

In a mobile telephone device applicable as an information processing apparatus, a protocol layer control unit controls a protocol layer used when a wireless communication is performed with a head set. A command queue puts an execution of a command to the protocol layer in a standby state. A request management unit manages piling up of requests accepted sequentially from the higher level layer in the command queue. A forced interruption unit requests the protocol layer control unit to disconnect a physical connection with the head set in a case where a forced interruption factor is generated. The protocol layer control unit is used to disconnect the physical connection with the head set. When a forced interruption request is accepted, a request management unit does not pile up the forced interruption request in the command queue but executes a forced interruption processing by the forced interruption unit.
