JPH1013947A - Phs having speech communication mode automatic switching feature - Google Patents

Abstract

PROBLEM TO BE SOLVED: To prevent omission of an incoming call in other modes at the time of a waiting operation by automatically switching a waiting state among inter- extension, home or public modes for every time interval previously predetermined time in advance. SOLUTION: A PHS extension is provided with an interrupt part 11 which detects time-out, an antenna 1, a radio part 2, a sound-processing part 3 which encodes and decodes sound data, a microphone 4, a speaker 5, a storing part 6 which stores data, a control part 7 which controls each part of the extension, a dial part 8 which performs a key operation, a display part 9 which shows dial data, etc., and an LED lamp 10 which notifies an incoming call. The PHS is provided with three speech communication modes which consists of an inter- extension mode, where speech communication is performed between extensions at a short distance via no line, a public mode where speech communication is performed in a state of a portable telephone feature and a home mode, where speech communication is performed in a state of a cordless telephone feature, automatically exchanges these speech communication modes at each predetermined time interval and waits.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a PHS having a function for public, home, and handset communication, and more particularly to a PHS having an automatic switching function between these communication modes.

[0002]

2. Description of the Related Art In a conventional PHS, it is possible to stand by only in one of a communication mode among a slave unit mode, a public mode, and a home mode. To change to another mode while waiting in the slave unit mode, the mode must be switched by a manual switch operation. For this reason, it is not possible to answer a call (incoming call) received in another mode during the standby operation in any of the handset mode, the home mode, and the public mode.

[0003]

SUMMARY OF THE INVENTION A PHS of the present invention has a cordless handset mode in which a call can be made between handset units in a short distance without passing through a line, a public mode in which a call is made in a mobile phone function state, and a cordless mode. 3 with home mode to talk in the telephone function state
It has three communication modes, and switches between these communication modes automatically at a predetermined time interval and waits.

Further, the PHS of the present invention switches to either the home mode or the public mode when waiting in the slave unit mode, and then returns to the slave unit mode, Next, the mode is switched to one of the home mode and the public mode, and the apparatus waits.

[0005]

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, an embodiment of the present invention will be described with reference to the drawings.

FIG. 1 shows the configuration of a PHS slave unit. FIG. 2 is a flowchart for explaining the call mode switching operation.

Referring to FIG. 1, a PHS handset includes an interrupt unit 11 for detecting time-out, an antenna 1 for transmitting radio waves, a radio unit 2 for transmitting / receiving data, and encoding / decoding of voice data. An audio processing unit 3, a microphone 4 for picking up sound, a speaker 5 for generating sound, a storage unit 6 for storing data, a control unit 7 for controlling each unit of the slave unit,
A dial unit 8 for performing key operations, a display unit 9 for displaying dial data and the like, and an LED lamp 10 for notifying an incoming call and the like
And

When FIG. 1 and FIG. 2 are used together,
1 reports to the control unit 7 a timeout every predetermined time (for example, 5 minutes) at a cycle set by the control unit 7. Based on the report, the process of FIG. 2 is started. As shown in the processing of FIG. 2, the current mode is referred to by the storage unit 6 and the mode to be switched is written to the storage unit 6 by the timeout of the software processing every predetermined time. Thereafter, the display unit 8 displays that the mode has been switched, and notifies the user. At this time, the setting of the wireless unit 2 is also set to the mode after the switching. FIG. 2 shows that when the mobile terminal is in the standby mode, the mobile terminal switches to the home mode or the public mode and waits. And an operation mode in which the mode is switched to any one of the public mode and waits.

[0009]

As described above, according to the present invention, the standby mode is automatically switched between the slave units, the home mode and the public mode at predetermined time intervals, so that other modes can be used during the standby operation. Can be prevented from leaking incoming calls.

Claims (2)

[Claims] 1. An inter-slave mode in which calls are made between short-distance handsets without passing through a line, a public mode in which calls are made in a mobile phone function state, and a home mode in which calls are made in a cordless telephone function state. A PHS having a call mode automatic switching function, characterized in that the call mode automatically switches between these call modes at every predetermined time and waits. 2. When waiting in the slave unit mode, the mobile terminal switches to one of the home mode and the public mode, waits, and then temporarily returns to the slave unit mode, and then returns to the home mode. 2. The PHS with a call mode automatic switching function according to claim 1, wherein the PHS switches to one of the public mode and waits.
