Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a mobile radio communication system used in a zone-configured mobile radio communication system, and more particularly to a mobile radio device adapted to perform variable control of transmission power based on a control signal from a mobile radio communication system network. .

2. Description of the Related Art FIG. 7 shows a configuration example of a mobile radio communication system having a zone configuration. In the mobile wireless communication system having such a configuration, the service area is divided into a plurality of zones 71, each zone 71 is provided with a base station 73 connected to the mobile wireless communication system network 72, and the mobile wireless device 74 is It communicates with the mobile radio communication system network 72 through the base station 73 in the zone 71 in which it is currently located.

In such a system, the mobile radio 74
During the communication between the mobile station and the base station 73, the mobile radio communication system 72 has a transmission power necessary and sufficient for the base station 73 and the mobile radio 74 to continue good communication in accordance with the change in the communication state. It is known that a so-called transmission power control method, in which a control signal is transmitted to the mobile wireless device 74 and the transmission power of the mobile wireless device 74 is increased or decreased within the range of the maximum transmission power, can be applied.
For this control, the maximum transmission power of each mobile wireless device 74 is stored in the storage device (means) 75 provided in the mobile wireless communication system 72. By performing the transmission power control, the average transmission power of the mobile wireless device 74 during communication is suppressed to be lower than the maximum transmission power of the mobile wireless device 74, so that radio wave interference to other wireless devices is reduced. There is an advantage that the power consumption of the mobile wireless device 74 can be reduced.

FIG. 8 shows an example of the configuration of a general mobile radio having a transmission power varying means used in the mobile radio communication system. The mobile radio is at least the radio body 1
The wireless device main body 1 and the battery pack 2 are each provided with a power supply connecting means 3, and the battery pack 2 is provided with a battery 4 for obtaining a predetermined power supply voltage. In addition, the storage device (means) 8 belonging to each mobile wireless device stores maximum transmission power information of the mobile wireless device or mobile station type information (information indicating which class it belongs to) determined according to the maximum transmission power. ) Is stored. The control circuit (means) 7 includes a transmission / reception circuit 10 and an antenna 11.
A control signal representing the maximum transmission power or the type of mobile station is transmitted to the base station 12 via a control channel (radio communication signal) via the control channel (radio communication signal) and moved to a storage device (means) 13 installed in the mobile radio communication system network. Performs a control operation to register the maximum transmission power information or the mobile station type information of the wireless device. This control operation is performed when the mobile radio is turned on. The maximum transmission power information or mobile station type information of the mobile radios registered at this time is fixedly assigned to each mobile radio, and one mobile radio is always assigned to one mobile radio. Maximum transmission power information or mobile station type information is registered. Further, the control circuit (means) 7 and the transmission power varying means 9 are based on a control signal representing a specific transmission power transmitted from the mobile radio communication system network to the mobile radio device via a control channel (radio communication signal). Then, the control operation for variably setting the transmission power of the mobile wireless device is performed.

In recent years, the use of portable mobile radios that are easy to carry has become popular. If the size of the battery pack 2 is reduced in order to enhance the convenience of carrying the portable mobile wireless device, the battery capacity is reduced to some extent. For this reason, by reducing the maximum transmission power of the mobile radio to reduce power consumption,
By compensating for the decrease in battery capacity, a standby time and a communication available time of a certain time or more were secured. In addition, as a method of extending the standby time and the communicable time of the mobile wireless device, in the conventional mobile wireless device, a large-capacity battery pack that can be connected to the same wireless device main body is separately prepared. .

Further, in recent years, since the operating voltage of various circuit components used in mobile radio equipment has been reduced,
It has been attempted to reduce the operating voltage of mobile radio devices to reduce power consumption. In this case, among the circuit components that make up the mobile radio device, the transmission power of the transmission amplifier circuit depends on the power supply voltage, so the maximum transmission power must be reduced for mobile radio devices that operate on a low-voltage power supply. It was Also,
When an external power source other than a battery pack, such as a car battery, is used in a low-voltage mobile wireless device, it is converted into a constant power source voltage by a constant voltage control circuit before use.

[0007]

However, in the above transmission power control method, the maximum transmission power information of the mobile wireless device or the mobile station fixedly assigned to the storage device (means) 8 belonging to each mobile wireless device. A mobile wireless device that performs a control operation of constantly registering one type of maximum transmission power information or mobile station type information in a storage device (means) installed in a mobile wireless communication system network is useful for communication time and carrying. However, there was a problem in securing a communicable area in a place where there are sparsely populated zones.

[0008] For example, in a portable type mobile wireless device which has been mainly used in recent years, a battery pack has been downsized in order to enhance convenience during carrying. In this case, there is a problem that the available communication time is shortened due to the decrease in battery capacity. In addition, in the case of a portable mobile radio that reduces power consumption by extending the maximum transmission power in order to extend the communication time, even if the transmission power required for communication is low in a dense zone, Since it is good, the communication quality does not deteriorate within the zone, but the maximum transmission power of the mobile radio is low in places where the zone is sparsely present, so the transmission power is insufficient at the end of the zone, resulting in As a result, there is a problem that the communication area becomes smaller than that of a mobile wireless device having a large maximum transmission power. In addition, if the power supply voltage is lowered to reduce power consumption and the maximum transmission power of the mobile wireless device is specified for use at low voltage, the mobile wireless device will operate even if a high voltage power source can be used. Maximum transmission power information cannot be changed because the maximum transmission power information is fixedly registered as low power assuming a low-voltage power supply, and a sufficiently wide communication area is secured in a non-existent place with sparse zones. However, there has been a problem in that there is no other method than using a large-sized mobile wireless device of another type with high transmission power, and the convenience of carrying the device is reduced.

Similarly, even when an external power supply is used, the maximum transmission power of the mobile radio is fixedly registered as low power assuming that a low-voltage battery is used as a power supply, and therefore the maximum transmission power is There is a problem in that it cannot be changed, and the expansion of the communication area cannot be expected as in the above case. Further, conventionally, a large-capacity battery pack that can be connected to the same radio unit that is prepared for longer standby time and communicable time in the mobile radio is generally large and increases the weight of the mobile radio. However, there is a problem that the convenience of carrying the device is reduced. Moreover, even if a large-capacity battery pack is used, the maximum transmission power of the mobile wireless device is fixedly registered, so that the maximum transmission power does not change, and there is a problem that it is not possible to expect the expansion of the communication area in the same manner as above. It was

The present invention solves the above problems and enables the same mobile radio to be flexibly used at a plurality of different maximum transmission powers, and flexibly according to the usage state and purpose of use of the user of the mobile radio. An object of the present invention is to provide a mobile wireless device capable of expanding a communicable area, prolonging a communicable time, diversifying a power supply voltage, and improving convenience when carried.
