JPH09261748A - Power-saving incoming notifying device of portable telephone - Google Patents

Abstract

PROBLEM TO BE SOLVED: To make the power consumption of a vibrator small by placing a high sensitivity data reception part, which is large in the power consumption of the vibrator, in operation only in a period in which the possibility that data are transmitted is high. SOLUTION: When a portable telephone terminates, a radio wave of, for example, 900MHz is sent to a base station as an ordinary terminating process. This radio wave of 900MHz is detected by a 900MHz detection part 10 and then a control part 12 operates the high-sensitivity vibrator data reception part 11 which receives a radio wave for high-sensitivity vibrator data receiving a radio wave for the vibrator. Consequently, the high-sensitivity reception part 11 which is large in power consumption can detect the radio wave of 900MHz. Therefore, only when the probability of termination is high, this reception part 11 can be placed in operation and the total power consumption of the vibrator 2 is reducible.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to power saving of a vibrator that notifies an incoming call to a mobile phone by vibration.

[0002]

2. Description of the Related Art In the conventional control of a vibrator for notifying an incoming call by vibration, a mobile phone transmits a call to a base station when an incoming call is received.
The vibrator is controlled by detecting a radio wave of 0 MHz. However, in the case of this method, the vibrator may detect a radio wave other than that of the mobile phone or may detect an incoming call to another mobile phone to cause the vibrator to malfunction.

Therefore, the present applicant has proposed a system in which a code for selecting a vibrator is transmitted from a mobile phone using a transmission wave dedicated to vibrator control, and only the vibrator that stores the code corresponding to this code is vibrated. Is proposing.

[0004]

However, in the case of this system, when a weak radio wave is used as a transmission wave dedicated to the vibrator, in order to detect an incoming call on the vibrator side, this weak radio wave is constantly monitored to detect an incoming call. There is a problem that a receiving circuit is required.

An object of the present invention was made in view of the above problems, and it is an object of the present invention to provide a vibrator that does not require a highly sensitive receiver and saves power.

[0006]

In order to solve the above problems, the present invention controls the vibration of a vibrator by transmitting an incoming wave to the mobile phone from the mobile phone to a vibrator data receiving section of the vibrator. In the incoming call notification device of the mobile phone, the vibrator is provided with a radio wave receiving section dedicated to the vibrator and a frequency detecting section for detecting the normal transmission frequency of the mobile phone, and the normal transmission frequency is detected by the frequency detecting section. The vibrator data receiving unit is operated.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Even in a system having a transmission wave dedicated to a vibrator, the present invention performs 900 MHz to a base station as a normal incoming call processing when a call arrives at a mobile phone.
The radio wave of is transmitted. Since the 900 MHz radio wave is larger than the transmission output of the transmission wave (weak) dedicated to the vibrator, the high-sensitivity receiving unit that receives the radio wave for the vibrator is operated after detecting this. By doing this,
The high-sensitivity receiver that consumes a large amount of power can detect a 900 MHz radio wave. Therefore, since the receiving unit can be operated only when the probability of incoming call is high, the power consumption of the entire vibrator can be reduced.

An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a mobile phone, and FIG. 2 is a block diagram of a vibrator.

Reference numeral 1 is a mobile phone main body, and 2 is a vibrator. The mobile phone body 1 includes antennas 3 and 4, a vibrator data transmitter 5, a transmitter 6, and a controller 7. The vibrator data transmission unit 5 transmits data for the vibrator. The control unit 7 controls the operation of the mobile phone body 1. The transmitter 6 transmits a normal transmission wave.

On the side of the vibrator 2, antennas 8, 9, 9 are provided.

5, switch 16. 900MHz detector 10
Is for detecting a normal transmission wave to a base station of a mobile phone. Vibrator data receiving unit 11, control unit 12
Controls the operation of the vibrator 2. Vibrator 2
Is activated by a control unit activation signal output from the 900 MHz detection unit 10 to the control unit 12, and controls the switch 16 to be turned on by a reception unit power supply control signal from the control unit 12. Power is supplied to the vibrator data receiving unit 11 to activate it. The data is determined, compared with the ID stored in the ID storage unit 14, and if they match, the motor 13 is activated,
If they do not match, the switch 16 is switched, the power supply 15 of the vibrator data receiving unit 11 is turned off, and the low power consumption mode is entered by itself. The vibrator data receiving unit 11 is for receiving a radio wave for a vibrator. The motor 13 is a motor for vibrating the vibrator casing.
It is. The ID storage unit 14 is for storing the selection code given to the vibrator 2.

As described above, the mobile phone 1 and the vibrator 2
When the mobile phone 1 receives an incoming call, first, as a normal incoming call process, a 900 MHz radio wave is transmitted to the base station. After the 900 MHz radio wave is detected by the 900 MHz detection unit 10, the control unit 12 controls the vibrator data reception unit 1 with high sensitivity to receive the radio wave for the vibrator.
1 is operated. By doing so, the receiving unit 11 with high power consumption and high sensitivity can detect a 900 MHz radio wave. Therefore, the receiving unit 11 can be operated only when the incoming call probability is high. Therefore, the power consumption of the entire vibrator can be reduced.

[0013]

As described above, according to the present invention, the power consumption of the vibrator is reduced by operating the high-sensitivity data receiving section with large power consumption of the vibrator only during the period when the probability of data transmission is high. It is possible to prolong the continuous use period of the vibrator.
