DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio communication device.

[0002]

2. Description of the Related Art Conventionally, a cordless telephone handset generally performs intermittent reception to save power consumption. Intermittent reception means that the tuner is not turned on at all times when the slave unit is in the idle state, and the tuner is turned on and off at regular intervals instead of keeping the tuner in standby mode.
Is repeated while the power of the tuner is ON, and the carrier of the radio wave is monitored. When the carrier is detected, the reception is set to the reception standby state for a certain time and the command reception from the master unit is waited.

[0003]

However, in the above conventional example, the power consumption is smaller than when the power of the tuner is always on, but the incoming command from the master unit is kept while the power of the tuner is off. Because it ignores
There was a problem that the response of the slave unit to the incoming call was delayed. Further, this problem is that when a cordless telephone is sequentially received in a telephone exchange connected with a plurality of cordless telephones, the time interval between the start of ringing of the first cordless telephone and the start of ringing of the last cordless telephone increases. It was also a point.

[0004]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, according to the present invention, a plurality of wireless communication devices are normally connected to another wireless communication device by using a manufacturer code preset in the wireless communication device. The time lag for executing the processing based on the transmitted information is shortened, and the radio communication apparatus keeps the intermittent reception stopped even if the information transmitted from another radio communication apparatus cannot be received on the way. The purpose is to prevent the In order to achieve the above object, the present invention provides, in a wireless communication device, means for performing intermittent reception, detecting means for detecting a carrier sent from another wireless communication device, and responding to the carrier detected by the detecting means.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS A first embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram of a telephone exchange apparatus accommodating a cordless telephone employing the present invention.
In FIG. 1, a telephone exchange 3 is connected to a digital communication network (ISDN) 1 and an analog communication network (PST) via a digital interface 7 and an analog interface 8, respectively.
N) 2. The telephone exchange 3 is connected to extension-dedicated telephones 4a, 4b and extension cordless telephones 4c, 4d, 4e via an extension interface 5. The voice information from each of these interfaces is exchanged in the communication path 6, and the control circuit 9 controls each interface and the communication path. Control circuit 9
A program for executing the control is stored in the ROM 10, and data necessary for the control is written and read to and from the RAM 11.

FIG. 2 is a block diagram of a cordless telephone base unit. The cordless telephone base unit is connected to a line from the telephone exchange 3 via an interface 14, and audio information is sent to the tuner 12 via an audio processing circuit 13. The control circuit 1 controls each circuit of the cordless telephone base unit and exchanges control signals with the slave unit.
5 does. A program for controlling the cordless telephone base unit is stored in the ROM 16, and writing and reading of data necessary for the control are performed on the RAM 17.

FIG. 3 is a block diagram of a cordless telephone handset. The cordless telephone handset performs wireless communication with the cordless telephone base unit by the tuner 18, the sound of the base unit is transmitted to the receiver 20 through the sound processing circuit 19, and the sound from the handset enters from the microphone 21 and is transmitted in the reverse path. Is passed on to the parent machine. The control circuit 22 controls the input of the key 25 and controls the display of the LCD 26 and the LED 27 in addition to the control of the voice processing. Programs for controlling these cordless telephone handsets are stored in the ROM 23, so that data necessary for control can be written,
Reading is performed on the RAM 24.

FIGS. 4 to 6 are flowcharts showing the control of the control circuit 22 of the cordless telephone handset adopting the present invention. In these flowcharts, only main parts related to the present invention are shown, and control parts not particularly related to the present invention are omitted.

First, FIGS. 4 and 5 will be described. Normally, the control circuit 22 of the cordless telephone handset performs intermittent reception (control of turning on / off the tuner at regular time intervals to suppress power consumption) (S401), but upon detecting a carrier of a control channel (S401). (S402), the intermittent reception is stopped, and a standby state for receiving signals while the tuner is on is entered (S403), and the timer 1 is started (S404).

Then, monitoring of command reception from the master unit is performed (S405). When timer 1 times out (S410) without receiving a command from the master unit,
The state returns to the intermittent reception state again. (Normally, timer 2 is not running, so it is in a timeout state.)
When a command is received from the master unit (S405), the I
It is determined whether D matches its own ID (S406).
Are coincident and are incoming commands (S40
7) Perform incoming call processing (S408), and if it is another command, perform the processing of that command (S409).

If the IDs do not match (S406), the maker code of the incoming command matches the maker code of its own ID, or
4 (S412), it is determined whether or not the mode is a mode in which intermittent reception is stopped when the maker code matches (S413), and if so, the timer 2 is started (the timer 2 has already been set). Restarts if has been started) (S414).
The timer 2 is set longer than the timer 1. The monitoring of the timer 2 is performed in (S411).
Due to the timeout, it returns to intermittent reception again. That is, if no command is received after the carrier is detected in (S402), the timer 1 times out and returns to intermittent reception again. If a command with an ID having a registered maker code is received, the timer 1, Alternatively, the timer 2 returns to intermittent reception due to the timeout of the longer timer.

[0013] In this manner, by continuously receiving an incoming command including a predetermined maker code, it is possible to quickly detect the next incoming command to the own device.

Next, FIG. 6 will be described. What is written in FIG. 6 relates to a method of registering and deleting a maker code to be compared, and a setting of a mode for stopping intermittent reception when the maker code matches. Registration and deletion of the maker code are performed using the key 25 of the slave unit. The key 25 includes a [setting] key in addition to the numeric keypad. [Setting] → [1] → [*] → [2] → [5] → [5] →
When the key is pressed with [#] (S501), the maker code 255 is registered in the RAM 24 (S502), and [Setting] →

[0] → [*] → [2] → [5] → [5] →
When the key is pressed with [#] (S501), the maker code 255 is deleted from the RAM 24 (S502). The same applies to the setting of the intermittent reception stop mode.
Press the key in the order of [2] → [*] → [1] → [#] (S
503) and the maker code match, so that intermittent reception is stopped (S504), [Settings] → [2] →
[*] →

[0] → [#] key is pressed (S503)
Then, a mode is set in which the intermittent reception is not stopped due to the match of the maker code (S504).

In the first embodiment, the timer 2 is restarted every time a maker code is received.
And the timer 2 does not have to be restarted with the second and subsequent commands. Although the registration and deletion of the maker code are performed in the RAM, the registration and deletion may be performed in a RAM, an EEPROM, a magnetic storage medium, an optical disk, or the like that is backed up by a battery. A method of registering in a storage medium and notifying the slave unit by radio waves is also conceivable. In addition, the registration mode of intermittent reception can be set by a physical switch,
The mode may be switched by a notification from the telephone exchange device.

If the same maker has two or more maker codes, those maker codes can be registered, and the maker code of a cordless telephone of another maker connected to the same telephone exchange, or its slave unit It goes without saying that the maker code of a cordless telephone of another maker that is within the range of radio waves may be used.

FIG. 7 is a flowchart showing another embodiment of registration of a maker code. [Settings] → [3] → [*] →

[0]
→ When the [#] key is pressed, a mode is set in which the maker code is automatically registered (S601). In this mode, when a maker code is received by a parent device to be registered, a command transmitted by the parent device is received (S603), and the maker code is read from the ID and registered (S604). This maker code registration mode is valid until the timer 3 times out (S602, S605).

[0018]

As is apparent from the above description, according to the present invention, a plurality of wireless communication devices are normally transmitted from another wireless communication device using a maker code preset in the wireless communication device. The time lag for executing the processing based on the transmitted information is shortened, and the radio communication apparatus keeps the intermittent reception stopped even if the information transmitted from another radio communication apparatus cannot be received on the way. Can be prevented.

Further, by using a maker code which is normally set in the apparatus in advance, it is possible to save the trouble of setting identification information common to the system such as a system ID in each of a plurality of wireless communication apparatuses in the system. it can.

Further, by making it possible to add or delete a maker code, it is possible to cope with a case where a new maker code is assigned due to lack of ID or the like.
