Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a composite mobile phone device, a wireless system automatic switching method according to the remaining battery level used therefor, and a program thereof, and more particularly to a method of switching those functions in a composite mobile phone device having a plurality of wireless system functions.
[0002]
[Prior art]
In recent years, in mobile phones, in addition to automobile phones, PDC (Personal Digital Cellular) systems, PHS (Personal Handy Phone System) systems, W-CDMA (Wideband Code Division Multiple Access) systems. Is adopted.
[0003]
The power consumption in each method is greatly different, and comparing the W-CDMA method and the PDC method, the W-CDMA method takes about 2/3 of the call time of the PDC method, but about 1/8 in standby. The difference in power consumption is large. Therefore, in the composite mobile phone device having both functions, when the remaining battery level is low, the PDC system can stand by and maintain a call, but the W-CDMA system cannot stand by and maintain a call. A condition occurs.
[0004]
Therefore, in the composite mobile phone device, for example, when signals can be transmitted / received by the PHS method and the PDC method, and simultaneous reception standby of signals by both methods is possible, it is simultaneously performed when the remaining battery level becomes a predetermined value or less. There is a method of canceling the reception standby mode, switching to reception standby by one of the PHS method and the PDC method, and stopping reception standby by the other method (for example, see Patent Document 1).

DETAILED DESCRIPTION OF THE INVENTION
Next, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a block diagram showing the configuration of a composite portable telephone device according to an embodiment of the present invention. Referring to FIG. 1, a composite mobile phone device 1 includes antennas 11 and 12, a radio system 13 using a PDC (Personal Digital Cellular) system, and a W-CDMA (Wideband Code Division Multiple Access) system. The wireless system 14 includes a control unit 15, a remaining operation time calculation unit 16, a battery remaining amount detection unit 17, and a recording medium 18, and the battery 2 is mounted.
[0015]
The control unit 15 controls the wireless systems 13 and 14 and the user I / F (interface) of the composite mobile phone device 1. The remaining battery level detection means 17 is under the control of the control unit 15, and the control unit 15 uses the remaining operation time calculation unit 16 and the remaining battery level detection means 17 to perform the remaining operation for the currently used wireless systems 13 and 14. Time and remaining operating time for the unused wireless systems 13 and 14 are obtained. The remaining operating time calculation unit 16 converts the remaining battery level detected by the remaining battery level detection means 17 into the remaining operating time for each of the wireless systems 13 and 14.
[0016]
When the control unit 15 detects that the remaining battery level detected by the remaining battery level detection unit 17 has decreased by a predetermined value or more, the control unit 15 switches the wireless systems 13 and 14 having the lowest power consumption as the first priority. Perform the action.
[0017]
FIG. 2 is a flowchart showing a control flow of the control unit 15 according to an embodiment of the present invention. In FIG. 2, the control unit 15 performs a battery remaining amount detection process, a determination process whether or not the remaining battery level is equal to or less than a predetermined value, a process when the wireless system currently used is the wireless system 13 using the PDC method, Processing is executed when the wireless system being used is the wireless system 14 based on the W-CDMA system. These processes can also be realized by executing a program stored in the recording medium 18 by the control unit 15 (computer of the mobile phone device 1 not shown). The operation of the cellular phone device 1 according to one embodiment of the present invention will be described below with reference to FIGS.
[0018]
If the remaining battery level is sufficient, the control unit 15 operates while switching between the PDC wireless system 13 and the W-CDMA wireless system 14 according to certain preset conditions and procedures. The above "certain conditions and procedures" are not directly related to the present invention, and thus the description thereof is omitted.
[0019]
The control unit 15 detects the remaining battery level using the remaining operation time calculation unit 16 and the remaining battery level detection means 17 asynchronously with the operations of the wireless system 13 using the PDC system and the wireless system 14 using the W-CDMA system. Do.
[0020]
That is, the control unit 15 performs the remaining battery level detection process (step S1 in FIG. 2) and the determination process (step S2 in FIG. 2) as to whether or not the remaining battery level is equal to or less than a certain value. When the number decreases and becomes a certain value or less, it is determined whether the currently used radio system is the PDC system or the W-CDMA system (step S3 in FIG. 2).
[0021]
If the wireless system currently used is the PDC system (the wireless system 13 using the PDC system), the control unit 15 operates the wireless system 13 using the PDC system with low power consumption. The fixing operation is performed (step S4 in FIG. 2). In this case, the control unit 15 does not perform the switching operation to the wireless system 14 by the W-CDMA system even when the switching to the wireless system 14 by the W-CDMA system is necessary, and the wireless system 13 by the PDC system. Continue the operation.
[0022]
On the other hand, if the wireless system currently used is the W-CDMA system (wireless system 14 based on the W-CDMA system), the control unit 15 operates with a large amount of power consumption in the wireless system 14 based on the W-CDMA system. Even if switching to the wireless system 13 using the PDC method is not necessary, switching to the wireless system 13 using the PDC method is performed (step S5 in FIG. 2), and if the wireless operation can be normally performed there (step 2 in FIG. 2). S6) The PDC wireless system 13 is fixedly operated (step S7 in FIG. 2).
[0023]
Here, if the wireless operation cannot be normally performed after the switching operation to the wireless system 13 by the PDC method (step S6 in FIG. 2), the control unit 15 returns the operation to the wireless system 14 by the W-CDMA method (step in FIG. 2). S8). However, the control unit 15 switches to the wireless system 13 by the PDC method again after a predetermined time (step S5 in FIG. 2), and when switching to the wireless system 132 by the PDC method can be normally performed (step in FIG. 2). S6) The operation is fixed to the wireless system 13 using the PDC method (step S7 in FIG. 2).
[0024]
In this way, in this embodiment, if the remaining battery level is sufficient, switching of the wireless system is performed according to the above conditions and procedures. However, when the remaining battery level decreases, the switching conditions and procedures are prioritized. In addition, an operation fixed to the most power-saving radio system is performed only when standby and a call can be maintained with a more power-saving radio system. As a result, in this embodiment, it is possible to effectively use all the remaining battery power, extending the operation time of the apparatus and extending the operation time.
[0025]
In this embodiment, the radio system is switched according to a certain condition or procedure. However, in a mobile device that operates a plurality of radio systems at the same time, by stopping only the radio system side with high power consumption, It is also possible to extend the operation time by suppressing power.
[0026]
【The invention's effect】
As described above, the present invention is equipped with a plurality of wireless systems using different wireless systems and includes a function of switching between a plurality of wireless systems according to radio wave conditions. When it is detected that the remaining battery level is below a preset value when the power is different, the operation time is reduced by preferentially switching to a wireless system with low power consumption and causing the wireless system to perform a fixed operation. The effect that it can be made longer is obtained.
