DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an electronic organizer having a radio telephone function.

[0002]

2. Description of the Related Art As a wireless telephone system, an automobile telephone or a portable telephone is becoming widespread. In this wireless telephone system, the slave unit can move from a service area of one base station (base station area) to a service area of another base station while talking. Alternatively, a call or an incoming call can be made from a car moving at high speed.

However, in order to realize such a function, the base station must always manage or know the current location of each slave unit. For this reason, the base stations need to be connected to each other by a computer, and the base station system becomes complicated and large-scale.

[0004] Also, since the base station manages the slave unit,
The number of slave units per base station is limited. Furthermore, in order to reliably realize the above-described functions, the transmission output of the slave unit must be relatively large, for example, 0.5 to 1 W, so that the battery life is shortened, and the slave unit is increased in size and weight. Would.

Therefore, there is a telepoint system as a next-generation wireless telephone system in contrast to such a wireless telephone system. This depends on the country, PHP (Japan), C
It is called T-2 (Europe), DECT ( Europe ) or the like.

[0006] In the telepoint system, also is intended to base station (telepoint base station) does not manage the handset in principle, in such a system
In this case , a call can be made from the slave, but cannot be received. When an incoming call is required, a predetermined key operation is performed so that the current location is notified from the slave unit to the base station in advance.

[0007] Further, since the base station does not manage the slave unit, the slave unit cannot move from the service area of one base station to the service area of another base station during a call. You can only move within the service area.

That is, the telepoint system is similar to a wireless public telephone or a cordless telephone having a wide portable range.

[0009] When there is no incoming call function as described above,
In the telepoint system, there is a restriction on the use of slave units. However, since the base station does not need to manage the slave units in principle, the base station can be configured with only a transceiver and a switch, greatly simplifying the base station. Can be

[0010] Further, since the slave unit is used near the base station and is not used while moving between different service areas,
The transmission output of the slave unit can be reduced to, for example, 0.1 W, so that the life of the battery can be prolonged.
Alternatively, the slave unit can be made smaller and lighter than a notebook.

[0011]

By the way, since the slave unit in the telepoint system can be reduced in size and weight as described above, it is conceivable to combine the slave unit and the electronic organizer.

That is, in this case, when making a call, the telephone number of the other party is searched by the telephone directory function (address book function) of the electronic organizer, and when the telephone number is displayed, a predetermined key is operated. The displayed telephone number is automatically dialed, and when the other party answers the telephone, a normal call can be made thereafter.

[0013] Therefore, not only can the range of use of the electronic organizer be expanded, but also it is possible to easily make a telephone call without fail and use it conveniently.

[0014] However, simply combining the handset with the electronic organizer simply wastes the battery by the handset even when the telephone function of the handset is not used, thereby shortening the life of the battery. turn into.

The present invention is intended to solve such a problem.
