Abstract

PROBLEM TO BE SOLVED: To make a possible continuous wait time long by performing plural different display processes simultaneously during a wait. SOLUTION: A low-speed clock mode is shifted to a high-speed clock mode through timer service. Further, a request to transmit a battery voltage detection request and a reception level notification request is set. Then a reception level notification request primitive is set. Then battery voltage detection is started. The reception level notification request primitive is sent out to a protocol control part 5. After the battery voltage detection, a display request of a liquid crystal display 4 is set. When the primitive is received from the protocol control part 5, the process is passed to B-level control. Then a reception level is read and the display request of the liquid crystal display 4 is set. Then a battery voltage level and the reception level are displayed on the liquid crystal display 4.

Detailed Description of the Invention

[0001]

TECHNICAL FIELD The present invention relates to a telephone,
In particular, the present invention relates to a telephone having a devised display updating process during standby.

[0002]

2. Description of the Related Art Telephones, such as PHS (Persona)
l Handyphone System) terminals,
Various displays are made to be useful for transmission / reception operations. Conventional PHS terminals, when updating a plurality of display information ,
For example, the battery voltage level reading process and the reception level reading process are separately activated, which wastes time.

In other words, conventionally, the timings of the voltage level processing and the reception level processing are not synchronized, and independent timers are started to perform completely independent processing, resulting in waste of time, and as a result. , The continuous standby time becomes shorter, and the length of the standby time has been a problem for phones that directly contribute to product appeal.

[0004]

SUMMARY OF THE INVENTION It is an object of the present invention to solve the above-mentioned problems of the prior art and to provide a telephone capable of lengthening the continuous waiting time.

[0005]

[Means for Solving the Problems] The telephone according to the present invention is
Central processing unit, protocol control unit, liquid crystal display
B) and are driven by a battery
A high-speed central processing unit for a telephone
When switching from clock mode to low-speed clock mode
Both switch to high-speed clock mode at a predetermined cycle
And, in this waiting high-speed clock mode,
The central processing unit sends the reception level to the protocol control unit.
From sending the notification request of to receiving level reading
Detect the battery voltage within the periodIt is a thing.

[0006] In addition, the telephone according to the present invention,Waiting
Central processing unit at low speed clock mode
To the high-speed clock mode to update the display information.
And then the central processing unit to high-speed clock mode.
From the phone to the low-speed clock mode,
From the low-speed clock mode to the high-speed clock
When switching to lock mode, multiple different display information
Start update process at the same time, and start update process of each display information
From the end of processing to the end of processing.
Use to update other display informationIs what you do.

The telephone according to the present invention is on standby.
Central processing in a predetermined cycle by the same timer service of
Move device from low-speed clock mode to high-speed clock mode
Battery voltage detection process and display
Read the reception level, and then
Processor from high-speed clock mode to low-speed clock mode
Is to be transferred to .

[0008] In addition, the telephone according to the present invention,protocol
The central processing unit is equipped with a control unit, and is connected to the protocol control unit.
To send the reception level notification request, and then set the reception level.
Detect the battery voltage within the period before readingAlso
Of.

[0009]

In the standby mode, a plurality of different display information update processes, for example, battery voltage detection process and reception level reading process are performed.
Start and taken simultaneously processed, by using the idle time between each processing step leading to processing end from start of each process executes each processing step with each other. In addition, the display information update process is periodically started at a predetermined cycle (for example, every 10 seconds), and, for example , the display of the battery voltage and the reception level is predetermined.
It updates at the cycle . In this way, the time during which the CPU operates with the high-speed clock can be shortened, and as a result, the battery life can be lengthened, and thus the continuous standby time can be lengthened.

1 is a block diagram of an embodiment of a telephone according to the present invention, which is implemented in a PHS terminal. In FIG. 1, 1 is a CPU (central processing unit),
Reference numeral 2 is a battery power source, 3 is a key input device, 4 is a liquid crystal display, 5 is a protocol control unit, 6 is an RF unit, and 7 is an antenna. The voltage level of the battery power source 2 is calculated by the CPU 1, and the reception level is the CPU 1 and the protocol control unit 5.
Obtained by communicating with.

FIG. 3 is a program configuration diagram showing the operation of the CPU 1 in the standby mode. P1. The timer service 30 shifts from the low speed clock mode to the high speed clock mode. Set the battery voltage detection request and reception level notification request transmission request (start)
To do. P2. The reception level notification request primitive is set by the RSSI task 37. P3. The battery voltage detection request is detected and the battery voltage detection is started. P4. The reception level notification request primitive is sent to the protocol control unit 5. P5. When battery voltage detection ends, liquid crystal display 4
Set the display request of.

P6. When the primitive is received from the protocol control unit 5, the process is passed to the B level control. P7. If it is a reception level notification, the process is passed to the RSSI task 37. P8. The reception level is read and the display request of the liquid crystal display 4 is set. P9. The liquid crystal display 4 displays the battery voltage level and the reception level (see FIG. 2). P10. The high-speed clock is changed to the low-speed clock, and the processing is ended.

The processing by the above steps P1 to P10 is periodically started by the CPU 1 at a predetermined cycle (for example, every 10 seconds), and the battery voltage and the reception level are updated and displayed. As described above, the idle time of a plurality of display processes is used to combine the processes, and the time during which the CPU 1 is operating at the high speed clock can be shortened, and as a result, the life of the battery 2 can be extended, and thus continuous. The waiting time can be extended.

The reception level and the battery voltage level
Although the example in which the display information update process is activated at the same time and displayed as shown in FIG. 2 has been described, the present invention is not limited to this, and the display information that needs to be updated regularly, for example , the display information of a clock, etc. Can also be done while waiting. Further, by configuring a plurality of different processing cycles to be stored in the ROM memory or the RAM memory and readable at the time of manufacturing the telephone, the battery life of the battery power source 2 (that is, continuous standby time) and The usability can be adjusted.
