JPH11243357A - Portable communication terminal - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent mismatching about power supply between a terminal body and a radio unit from occurring by transferring power management information to a body part when a radio unit storing the power management information is attached to the body part. SOLUTION: A removable radio unit A 10 and a radio unit C 20 can be attached and detached to/from a portable communication terminal body B 30. Since power supply management data A assumes PHS correspondence, it can be driven even when power consumption at the time of speech communication is small. On the other hand, since power supply management data C assumes a radio carrier, it can not be driven unless power consumption at the time of speech communication is large. When the unit A 10 or the unit C 20 is attached to the body B 30, the data A or the data D stored in storing parts A 14 or C 24 of the units A 10 or C 20 is transferred to the body B 30 and the power management of an attached radio unit is performed based on the management data.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio processing unit which can use a plurality of or a single radio carrier, stores power management information, and notifies the main body of the power management information of the radio processing unit. The present invention relates to a mobile communication terminal whose unit performs power management.

[0002]

2. Description of the Related Art A conventional portable communication terminal is a portable communication terminal that can use a plurality of wireless carriers, and has a configuration in which a processing unit unique to the wireless carrier can be selectively connected to a wireless processing unit. The power consumption varies depending on the characteristics of the wireless carrier of the wireless unit to be connected. When a portable communication terminal having a plurality of functions supports only a single power supply, a specific wireless unit can be driven, but other wireless units may not be able to be driven. In other words, it may not be suitable for a call using the cellular telephone function, but may be suitable for a call using the PHS.

[0003]

However, in such a conventional portable communication terminal, when a configuration in which a wireless unit can be replaced is adopted, information of a main body for notifying power consumption is transmitted to the wireless unit. Power consumption of the mobile communication terminal, and there is a possibility that the notification of the remaining battery level to the user of the mobile communication terminal becomes meaningless. That is, there is a possibility that a battery level warning is issued even though there is enough battery level relative to the power consumption of the wireless unit being used, or that there is not enough battery level to activate the wireless unit In some cases, the remaining battery level warning may not be issued.

[0004]

SUMMARY OF THE INVENTION The present invention has been made to solve these problems, and has a display unit and an operation function, and a main unit for controlling these functions. In a portable communication terminal configured with a wireless unit, when a wireless unit storing power management information such as a minimum drive power supply voltage for driving the portable communication terminal and a remaining value of a power supply battery is attached to the main body unit. A portable communication terminal in which the power management information is transferred to a main body and power management is performed by the main body.

Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of the portable communication terminal of the present invention, and FIG. 2 is a diagram illustrating the usage time and the remaining battery power of each wireless unit used in the portable communication terminal of the present invention. In FIG. 1, reference numeral 10 denotes a wireless unit A, 11
Is a wireless unit A, 12 is a protocol processing unit A, 14 is a storage unit A in which power management data A is stored, and 13 is a connection unit. Similarly, 20 is a wireless unit C, 21 is a wireless unit C,
22, a protocol processing unit C; 24, a storage unit C in which power management data C is stored; and 23, a connection unit. 30 is a mobile communication terminal device main body B, 31 is a speaker, a microphone,
Equipment such as keys and LCD, 32 is a man-machine I /
F processing unit, 33 is a power supply processing unit, 34 is a battery, and 35 is an external power supply. And these wireless units A (10)
The wireless unit C (20) can be attached to and detached from the portable communication terminal device body B (30).

The operation will be described with reference to FIGS. 1 and 2. Removable wireless unit A (10) and wireless unit C capable of using multiple or single wireless carriers
(20) can be attached to and detached from the portable communication terminal device body B (30). The wireless unit A (10) and the wireless unit C (20) hold a protocol processing unit A (12) and a protocol processing unit C (22) that hold unique information, and a storage unit A that has different power consumption. (14) and the power management data A (14) and the power management data C (2) in the storage unit C (24), respectively.
4) is stored.

Here, the power management data A (14) is PH
Since it is assumed to be compatible with S, it is possible to drive with low power consumption during a call. On the other hand, since the power management data C (24) assumes a wireless carrier, it cannot be driven unless power consumption during a call is large. In this manner, the wireless unit A (1) which can be attached to the portable communication terminal device body B (30)
0) and the wireless unit C (20) have different power consumptions when driven. That is, the wireless unit A
In the case of (10), the power consumption shown in FIG. 2 indicates b, and in the case of the wireless unit C (20), the power consumption shown in FIG. 2 indicates a.

Next, such a radio unit A (10)
Alternatively, when the wireless unit C (20) is mounted on the portable communication terminal device main body B (30), the data is stored in the storage unit A (14) or the storage unit C (24) of the wireless unit A (10) or the wireless unit C (20). The stored power management data A (1
4) Or the power management data C (24) is transferred to the portable communication terminal device main body B (30),
(30) performs power management of the mounted wireless unit based on the power management data.

[0009]

As described above, according to the present invention, when the wireless unit storing the power management data is mounted on the main body of the portable communication terminal device, the power management data is transferred to the main body of the portable communication terminal device and the portable communication terminal device is provided. Since the power management is performed on the main body based on the transferred power management data, there is no occurrence of power mismatch between the portable communication terminal device main body and the wireless unit.
