DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a composite terminal for mobile communication having transmission / reception functions of a plurality of different mobile communication systems (for example, a cordless type and a cellular type).

[0002]

2. Description of the Related Art Conventional multi-function terminals for mobile communication are:
This will be described with reference to FIG. FIG. 6 is a block diagram showing an example of the configuration of a conventional mobile communication complex terminal. The mobile communication terminal 200 has transmission / reception functions of two types of mobile communication systems. Hereinafter, one of these two types of mobile communication systems will be referred to as a first system, and the other will be referred to as a second system.

[0003] The mobile communication complex terminal 200 has a first
A first wireless receiving unit 1, a first channel codec 2, a first voice codec 3, and a first wireless transmitting unit 9 (hereinafter, these circuit units are collectively referred to as a first system dedicated circuit unit 201) used only for the system. ) And a second radio receiving unit 5, a second channel codec 6, a second audio codec 7, and a second radio transmitting unit 10 used only for the second system (hereinafter, these circuit units are collectively used exclusively for the second system). Circuit unit 202). Note that the first channel codec 2 and the second
Each of the channel codecs 6 is a circuit that encodes and decodes signals other than audio signals such as channel assignment signals. Each of the first audio codec 3 and the second audio codec 7 is a circuit that encodes and decodes an audio signal.

On the other hand, a receiver 4, a microphone 8, a power supply unit 1
1, the control unit 12 and the operation unit 13 are configured to be commonly used in any of the methods. here,
The control unit 12 is a circuit that controls the operation of the entire mobile communication multifunction terminal 200. The operation unit 13
Is a member operated when performing various operations such as turning on / off the power, making a call, and receiving a call. Further, the operation unit 13 is used for selecting whether to use both of the two types of mobile communication systems or to use only one of the above two types of mobile communication systems when waiting for reception. Here, when both mobile communication systems are set to be used, the control unit 12 controls the power supply unit 11 so that both the first system dedicated circuit unit 201 and the second system dedicated circuit unit 202 supply power. Supply.

Here, when an incoming call of the first radio receiving unit 1 is detected, the received data is decoded into an audio signal via a first channel codec 2 and a first audio codec 3,
The sound is reproduced by the receiver 4 as audio. When transmission is performed, the voice from the microphone 8 is encoded via the first voice codec 3 and the first channel codec 2 and transmitted from the first wireless transmission unit 9 to the other party. on the other hand,
When an incoming call of the second wireless receiving unit 5 is detected, the received data is decoded into an audio signal via the second channel codec 6 and the second audio codec 7, and is reproduced by the receiver 4 as audio. When transmitting the signal, the sound from the microphone 8 is encoded through the second sound codec 7 and the second channel codec 6, and the second wireless transmission unit 1
Call from 0 to the other party. As described above, when the reception standby mode is set so that both the first method and the second method are used, the transmission method of the other party can be the first method or the second method.
Calls can be received by any of the methods.

On the other hand, when setting is made so as to perform reception standby using only one of the mobile communication systems, for example, when setting is made to use only the first system, the control unit 12 By controlling the power supply unit 11, the first
Power is supplied only to the system dedicated circuit unit 201, and power supply to the second system dedicated circuit unit 202 is cut off. With this configuration, power consumption in the second-system dedicated circuit unit 202 is eliminated, so that consumption of the battery can be suppressed and reception for a long time can be performed. Obviously, the same effect can be obtained even when the setting is made so as to use only the second method, contrary to this example.

[0007]

However, as described above, when the reception standby is set so as to use all of a plurality of different mobile communication systems, it is sure that the mobile phone always arrives regardless of the transmission system of the other party. Although it is very convenient because it can be called, the power consumption becomes large because all the circuit parts need to be operated all the time, and the battery is significantly consumed. As a result, the reception standby time becomes shorter,
The battery needs to be charged frequently, which is very troublesome. In addition, there is a concern that the battery runs out during use of the terminal and communication becomes impossible. On the other hand, among a plurality of mobile communication systems,
When the reception standby is set using only one of the methods, the consumption of the battery can be suppressed, and the reception standby can be performed for a long time. However, when the other party makes a call using another mobile communication system that is not set by the user, there is a problem that the call cannot be received.

[0008] Basically, among a plurality of different mobile communication systems, a system that consumes the least power during standby for reception is normally used, and another system or all systems are used only when necessary. Ideally, such switching of the mobile communication system generally needs to be performed manually. Therefore, for example, once switching from the normally used method with the lowest power consumption to another method with large power consumption, the reception standby continues in the method with large power consumption unless manually returning to the normal method again. As a result, battery consumption increases.

[0009] Here, Japanese Patent Application Laid-Open No. 9-163450 proposes a mobile communication composite terminal in which switching of the mobile communication system is automated. In this prior art,
Of the two different mobile communication systems, a predetermined first system is set in a reception standby state, and it is checked whether or not it can be registered in a base station of this mobile communication system. The system is set to wait for reception, and if registration in the first system is not possible in the above check, control is performed so that registration in the second system different from the first system is performed. Switching is automated.

[0010] If this technique is used, an operation is normally performed in which the first system consuming less power usually waits for reception and automatically switches to the second system in an area where the first system cannot be used. In addition, the battery can be maintained for a long time while suppressing power consumption. However, for example, when the user separates the time zone according to his / her own lifestyle and wants to change the standby mode for each time zone, when switching the mobile communication mode based on time and time, After all, there remains a problem that the terminal must be manually operated.

[0011] The present invention relates to a mobile communication multi-functional terminal having a plurality of different mobile communication system transmission / reception functions, when a predetermined time has elapsed, or when a current time has reached a predetermined time. It is an object of the present invention to provide a mobile communication complex terminal having means for automatically switching the mobile communication system from a currently used system to another system set in advance.

[0012]

In order to achieve the above object, a mobile communication multi-function terminal according to the present invention comprises a plurality of mobile communication multi-function terminals having transmission / reception functions of different mobile communication systems. A setting storage unit that stores settings related to the switching of the mobile communication system, and a timer that performs counting are provided, and when the count of the timer reaches a preset switching time, the mobile communication system is currently in use. There is a means for automatically switching from one method to another preset method. In this case, among the plurality of different mobile communication systems, a certain mobile communication system is set as a default system that is normally used, and when the mobile communication system is switched from the default system to another system, the timer is simultaneously used. To start counting and when the timer count reaches a preset switching time,
It is preferable that the mobile communication system is automatically returned to the default system.

Also, in a mobile communication composite terminal having transmission / reception functions of a plurality of different mobile communication systems, a setting storage unit for storing a setting relating to switching of the mobile communication system, a real-time clock for obtaining a current time, and And a means for automatically switching the mobile communication system from the currently used system to another predetermined system when the current time reaches a predetermined switching time. In this case, the setting storage unit can store a plurality of combinations of the switching time and the mobile communication scheme after the switching, and each time the current time reaches the switching time, the mobile communication scheme is set to the current setting. It is preferable to be able to automatically and automatically switch from the method in use to another method set in advance. In the mobile communication complex terminal according to the present invention, if the mobile communication system switching time comes during communication, the mobile communication system switching is not performed at that time, and there is no delay after the communication ends. It has means for switching.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of a multi-terminal for mobile communication according to the present invention will now be described.
An example of a mobile communication complex terminal having a transmission / reception function of various types of mobile communication systems will be described with reference to FIGS. One of the two types of mobile communication systems is referred to as a first system, and the other is referred to as a second system. In the present embodiment, one or both of the first method and the second method can be arbitrarily set as a default method that is normally used. Hereinafter, a case where the first method is the default method will be described. I do. Here, in the present embodiment, when the mobile communication system is switched from the first system, which is the default system, to the second system, the mobile communication system is automatically returned to the first system after a lapse of a predetermined time ( Hereinafter, it is referred to as a timer mode). Hereinafter, the timer mode will be described.

FIG. 1 is a block diagram showing a first embodiment of a digital mobile communication complex terminal according to the present invention. The mobile communication complex terminal 100 includes a first wireless receiving unit 1, a first channel codec 2, a first audio codec 3, a receiver 4, a second wireless receiving unit 5, a second channel codec 6, and a second audio codec 7. , A microphone 8, a first wireless transmission unit 9, a second wireless transmission unit 10, a power supply unit 11, a control unit 12, and an operation unit 13. The circuits 1 to 13 denoted by the same reference numerals corresponding to FIG. 6 perform the same operations as the circuits 1 to 13 constituting the above-described conventional mobile communication multifunction terminal 200. .

In the present embodiment, in order to realize the timer mode, in addition to the circuits 1 to 13 described above, a setting storage unit 14 for storing settings relating to switching of the mobile communication system, and a timer for counting time. 15. FIG. 2 is a time chart showing an automatic switching operation of the mobile communication system in the timer mode. As shown in FIG.
By operating the operation unit 13 while the power supply is turned on, an arbitrary switching time t can be set in advance. The switching time t is a parameter stored in the setting storage unit 14, and is used to set a time period until a user automatically switches back to the first mode when switching the mobile communication mode to the second mode. It is.

The switching time t is maintained in the setting storage unit 14 even if the power of the mobile communication terminal 100 is turned off, unless the user resets the setting. Therefore, when the power is once turned off after the switching time t is set and then turned on again, the timer mode functions according to the previously set switching time t. In the present embodiment, before the mobile communication system is switched to the second system, the switching time t is determined in advance.
Was set up, but the first method, which is the default method, was used.
Each time the switching operation from the system to the second system is performed, the setting may be made one by one.

When the mobile communication system is switched from the first system, which is the default system, to the second system by operating the operation unit 13, the timer 15 is simultaneously operated.
Starts and starts counting, and enters the timer mode. Thereafter, until the count reaches the switching time t, the control unit 12 operates each circuit so as to perform reception standby using only the second method, and accepts only an incoming call according to the second method. Then, when the count reaches the switching time t, the control unit 12 operates each circuit again to use only the first method, which is the default method, and returns to a state of accepting only an incoming call by the first method. . Thereafter, the mobile communication system is changed from the first system to the second system.
When the system is switched to the system, the timer mode is set, and the above-described operation is repeated.

As described above, in this embodiment, when the mobile communication system is switched from the first system, which is the default system, to the second system, the mobile communication system is automatically returned to the first system after a predetermined time has elapsed. Since it has the means, it is not necessary to manually return to the first method every time switching to the second method is very convenient. Furthermore, if a mobile communication system with low power consumption is selected as the first system, which is the default system, battery consumption can be suppressed, so that a long standby time can be achieved. Here, the case where the default system is switched from the first system to the second system has been described. Of course, the same operation is performed when the first system is switched to use both types of mobile communication systems. Is what you do.

By utilizing the timer 15, not only the automatic return operation to the default system normally used as in the first embodiment, but also the automatic switching of the mobile communication system in various variations can be performed. it can. FIG. 3 is a time chart showing an example of an automatic switching operation of the mobile communication system using the timer 15.
In this way, the combination of the switching time t and the mobile communication system after the switching is stored in the setting storage unit 14 in advance, and the user can start counting of the timer 15 at an arbitrary time. Then, when the count reaches the switching time t, an operation of switching the mobile communication system from the currently used system to another predetermined system can be easily set. As described above, in the mobile communication complex terminal 100 according to the present invention, the mobile communication system can be automatically switched based on time so as to conform to the lifestyle of the user.

Next, a second embodiment of the mobile communication multi-terminal according to the present invention, similar to the first embodiment described above, has a mobile communication multi-terminal having transmission / reception functions of two types of mobile communication systems. Will be described as an example with reference to FIGS. 4 and 5. Here, one of the two types of mobile communication systems will be referred to as a first system, and the other will be referred to as a second system. In the present embodiment, there is provided a means (hereinafter, referred to as a clock mode) for automatically switching the mobile communication system from the currently used system to another predetermined system when the current time reaches a predetermined time. are doing. Hereinafter, the clock mode will be described.

First, FIG. 4 is a block diagram showing a second embodiment of a digital mobile communication complex terminal according to the present invention. As in the above-described first embodiment, the mobile communication multi-function terminal 101 includes a first radio receiving unit 1, a first channel codec 2, a first voice codec 3, a receiver 4, a second
It includes a wireless receiving unit 5, a second channel codec 6, a second audio codec 7, a microphone 8, a first wireless transmitting unit 9, a second wireless transmitting unit 10, a power supply unit 11, a control unit 12, and an operation unit 13. . The circuits 1 to 13 denoted by the same reference numerals corresponding to FIG. 6 perform the same operations as the circuits 1 to 13 constituting the above-described conventional mobile communication multifunction terminal 200. .

In the present embodiment, in order to realize the clock mode, in addition to the circuits 1 to 13 described above, a setting storage unit 14 for storing settings relating to switching of the mobile communication system, And a real-time clock 16. FIG. 5 is a time chart showing an automatic switching operation of the mobile communication system in the clock mode. As shown in the figure, the user operates the operation unit 1 while the power of the mobile communication multifunction terminal 101 is turned on.
By operating 3, a combination of the switching time T and the mobile communication system M after the switching can be set in advance and stored in the setting storage unit 14.

Thus, the user can arbitrarily set the mobile communication method to be switched to when and which method. In the clock mode in which such setting is performed, the control unit 12 always compares the current time obtained from the real-time clock 16 with the switching time T stored in the setting control unit 14,
When the current time coincides with the switching time T, the control unit 12 controls the power supply unit 11 and the like to automatically switch the mobile communication system from the currently used system to another preset system.

The combination of the switching time T stored in the setting storage unit 14 and the mobile communication system M after the switching will not change unless the user resets the combination. Even if the power is turned off, the setting is kept in the setting storage unit 14. Therefore, if the power is once turned off after the combination of the switching time T and the mobile communication system M after the switching is set and then turned on again, the clock mode functions according to the previous setting.

Here, the setting storage unit 14 stores the combination of the switching time T and the mobile communication system M after the switching as (T1, M1), (T2, M2),.
i, Mi), and the mobile communication system is automatically switched to Mi each time the switching time Ti is reached, so that more detailed automatic switching setting can be performed. it can. In the following, as combinations of the switching time T and the mobile communication system M after the switching, (T1; 9:00, M1; only the second system), (T2; 14:00, M2; the first system and the second system) Both cases) and (T3; 20:00, M3; only the first method) will be described.

Here, the mobile communication composite terminal 10
The case where the first system is selected as the mobile communication system at the time when the power supply 1 is turned on will be described as an example. First, at the time when the current time becomes 9 o'clock, the mobile communication system is automatically switched from the first system to the second system, and the reception standby is performed using only the second system. For example, if the user frequently moves at high speed by car or the like between 9:00 and 14:00, a stable incoming call can be made by setting a cellular type or the like as the second method. Next, the current time is 14
At the time, the mobile communication system is automatically switched to use both the first system and the second system, and is in a state of waiting for the widest reception. For example, in the lifestyle of the user, the time zone with the highest frequency of incoming calls is from 14:00 to 20
Until time, such a setting allows an incoming call to be made regardless of the mobile communication system of the other party. Then, when the current time reaches 20:00, the mobile communication system is automatically switched to use only the first method, and reception standby is performed using only the first method. For example, if there are not many incoming calls after 20:00 in the lifestyle of the user, a cordless type with low power consumption may be set as the first method. By doing so, the consumption of the battery can be suppressed, so that the reception standby time becomes longer and the number of times of charging can be reduced.

As described above, the present embodiment has a means for automatically switching the mobile communication system from the currently used system to another predetermined system when the current time reaches a predetermined time. Therefore, the mobile communication system can be automatically switched on the basis of time so as to conform to the lifestyle of the user.

In the first and second embodiments, when the count of the timer 15 reaches the switching time t during communication, or when the current time reaches the switching time T, The control unit 12 controls the power supply unit 1 so that the mobile communication method is not switched at a point in time and switched without delay after the communication is completed.
1 and so on. This makes it possible to avoid a situation in which the mobile communication method is forcibly switched during communication and communication is suddenly interrupted.

In the first and second embodiments described above, for simplicity of description, a composite terminal for mobile communication having transmission / reception means of two types of mobile communication systems will be exemplified. Although the description has been made, the present invention is naturally applicable to a case where the number of the mobile communication systems is two or more.
The timer 15 and the real-time clock 16
May be combined to provide a mobile communication composite terminal.

When the count of the timer reaches a preset switching time, there is a means for automatically switching the mobile communication system from the currently used system to another preset system, It is possible to automatically switch the mobile communication system on a time basis in accordance with the lifestyle of the user.

In particular, when a certain mobile communication system among a plurality of different mobile communication systems is set as a default system that is normally used, and the mobile communication system is switched from the default system to another system, the mobile communication system is simultaneously operated. A timer is started to start counting, and when the timer count reaches a preset switching time, if the mobile communication method is automatically returned to the default method, switching to a method other than the default method is performed. This is very convenient because you do not have to manually revert to the default method each time. Furthermore, if a mobile communication system with low power consumption is selected as a default system, battery consumption can be suppressed, so that a long standby time can be achieved.

Further, in the mobile communication multi-terminal according to the present invention, which has a function of transmitting and receiving a plurality of different mobile communication systems, a setting storage unit for storing a setting relating to the switching of the mobile communication system, and a current time is obtained. Since a real-time clock is provided, and when the current time reaches a preset switching time, the mobile communication system has a means for automatically switching from a currently used system to another preset system, The mobile communication system can be automatically switched based on the time so as to conform to the lifestyle of the user. In this case, the setting storage unit can store a plurality of combinations of the switching time and the mobile communication scheme after the switching, and each time the current time reaches the switching time, the mobile communication scheme that is currently being used is If it is possible to automatically switch from one method to another method set in advance, more detailed settings can be made.

On the other hand, in the mobile communication complex terminal according to the present invention, if the mobile communication system switching time comes during communication, the mobile communication system switching is not performed at that time, and the communication termination is not performed. Since a means for switching later without delay is provided, it is possible to avoid a situation in which the mobile communication method is forcibly switched during communication and communication is suddenly interrupted.
