The slave unit PS1 is a slave unit whose wireless communication is managed by a master unit CS1 having a self-operating base station function. The above-described embodiment may be applied to a wireless terminal device such as a PHS system, a PDC system which is a general portable wireless telephone system, or a future portable wireless telephone system to which a CDMA system is applied.

Here, the relationship between the radio zone RZ1 managed by the master unit CS1 and the master unit CS1 will be described.

Master unit CS1 transmits a notification information signal from antenna 25 at intermittent reception intervals in order to notify slave unit PS1 of its existence. The broadcast information signal is a signal in which a configuration of a wireless channel, a configuration of a control carrier, operation information of the system, and the like are carried. In addition, the notification information signal is
1 to notify various information of the wireless system,
1 is a signal serving to guide the user to find the system to which the user belongs. Normally, in a range where the notification information signal reaches, the master unit CS1 can manage the wireless communication of the slave unit PS1.

In a PHS public base station, there is a difference depending on the output power.
It is assumed that the range is from m to 200 m. The performance is the same as that of the master unit used in ordinary households. Even when the user is outdoors, the slave unit can detect the information signal from the master unit indoors to some extent, and the master unit and the child unit You can talk to the machine.

FIG. 4 shows a master unit CS1 of the above embodiment,
FIG. 7 is a diagram illustrating a reception level value corresponding to a distance from a slave unit PS1.

Generally, the reception level value increases when the slave unit PS1 approaches the master unit CS1, and decreases when the slave unit PS1 moves away from the master unit CS1.

FIG. 5 is a diagram showing a detailed example of the reception level table 20 in the above embodiment.

In the above embodiment, the reception level threshold is set to Y
a. Here, the reception level threshold setting means will be described. The actual value of the reception level threshold Ya is based on the slave unit PS1.
Users greatly depend on the environment in which the system is used. As described above, in the wireless zone RZ1 having a radius of approximately 100 m to 200 m, the slave unit PS1 can receive the notification information signal transmitted by the master unit CS1, and the radio wave transmitted from the slave unit PS1 Wireless zone R
If it is within Z1, it reaches master unit CS1.

However, when the facsimile interception function of the base unit CS1 is set, the base unit CS1
When the facsimile interception function is immediately released after receiving the radio wave from the base station CS1, the user of the base station PS1
If the reception level value that is far from
A predetermined reception level value may not be obtained. At that time, the facsimile data is transmitted from the master unit CS1 to the slave unit PS1.
May not be received.

Therefore, in the above embodiment, the slave unit PS1
User can give an instruction to set the reception level threshold at a place that meets his / her condition. For example, suppose that the user of the slave unit PS1 wants to set or cancel the facsimile interception function when coming to the entrance of the house. In this case, when the user of the slave unit PS1 comes to the entrance of the house, the slave unit PS1
Are operated by the user. Next, slave unit PS1 transmits the setting instruction to master unit CS1. Master device CS1 that has received the setting instruction writes the reception level value at that time as a reception level threshold value in reception level table 20. Through the above operation, a setting instruction of the reception level threshold can be issued.

If the user of the slave unit PS1 wants to immediately release the facsimile substitute reception function when he / she comes near the house, the reception level is lower when the reception level value is lower than in the above-described embodiment away from the house. A threshold may be set. However, if the setting is made at an extremely low reception level value, a predetermined reception level value may not be obtained due to the influence of radio waves, ambient noise, or the like.
1 may not be able to output facsimile data.

The reception level table 20 stores the reception level value Yp of the previous measurement. This is for comparing the currently measured reception level value Ym with the previously measured reception level value Yp to determine whether the slave unit PS1 is approaching or leaving the master unit CS1.

FIG. 6 is a flowchart showing the control operation of the master unit CS1 according to the above embodiment.

In FIG. 1, slave unit PS1 is connected to master unit CS1.
The case of moving from outside the wireless zone RZ1 to the inside and the case of moving from inside the wireless zone RZ1 to the outside will be described.

In the state of the normal operation, in order to notify the location of the own radio zone RZ1, the base station CS1 transmits a notification information signal to the handset PS1 at intermittent reception intervals.
Then, the radio wave such as the response signal transmitted from the slave unit PS1 is monitored by the reception state monitoring means 21 and the standby state is established (S
601).

At this time, the slave unit PS1 receives the broadcast information signal intermittently transmitted from the master unit CS1 while the radio unit 30 is in the standby state.
1 is periodically received.

When the slave unit PS1 enters the radio zone RZ1, the broadcast information signal transmitted from the master unit CS1 can be received although the reception level value is still low. Slave unit P
When S1 receives the broadcast information signal, it is known that the base station CS1 exists within a range where the own radio wave can reach, and the radio wave transmitting / receiving means 30 transmits a response signal such as a position registration signal to the base station CS1 to the broadcast information signal. Send to

When a radio wave is received from the slave unit PS1 (S60)
1) The reception level monitoring unit 21 measures the reception level value Ym received from the slave unit PS1 (S602). The measured reception level value Ym is first compared with the reception level threshold value Ya stored in the reception level table 20 (S60).
3) If they do not match, terminate without doing anything. As shown in FIG. 4, the distance between slave unit PS1 and master unit CS1 is X
Until the position a is reached, the measured reception level value Ym is
Since the value is lower than the reception level threshold value Ya, the measured reception level value Ym does not match the reception level threshold value Ya.

When the measured reception level value Ym matches the reception level threshold value Ya (S603), the measured reception level value Ym is compared with the reception level value Yp of the previous measurement (S604, S606). As a result of the comparison, when the measured reception level value Ym is smaller than the reception level value Yp of the previous measurement (S604), it is determined that the slave unit PS1 is moving away from the master unit CS1, and the facsimile proxy reception means 22 performs the facsimile operation. The alternate reception function is set (S60
5). After setting, received facsimile data,
It is stored in the storage means 24.

If the measured reception level Ym is larger than the reception level Yp measured last time (S606), the slave unit P
It is determined that S1 is approaching the master unit CS1, and the facsimile proxy reception unit 22 releases the facsimile proxy reception function (S607). After the cancellation, the received facsimile data is transmitted to the slave unit PS1.

If the previously measured reception level value Yp and the measured reception level value Ym are the same, the slave unit PS1 and the master unit C
It is determined that the distance from S1 does not change, and nothing is performed.

In the above embodiment, if the reception level threshold value Ya and the measured reception level value Ym match in step S603, the flow advances to step S604 to compare the measured reception level value Ym with the reception level value Yp measured last time. I do. However, in step S603, instead of setting the reception level threshold Ya, a predetermined range A (for example,
(A range of “Ya−b” to “Ya + b”), and the process may proceed to step S604 when the measured reception level value Ym is within the range of A.

According to the above embodiment, in the base station CS1, the user of the base station PS1 sets or cancels the facsimile proxy reception function of the base station CS1 by instructing the setting of the reception level threshold value from the base station PS1. Depending on the location of the user, the user does not need to perform the operation manually,
There is an effect that the facsimile proxy reception function of the master unit CS1 can be exhibited.

FIG. 7 is a flowchart showing a control operation when the parent machine CS1 of the above embodiment receives facsimile data.

The facsimile proxy receiving means 22 receives facsimile data via the public network interface means 23 (S701). Facsimile proxy receiving means 22
In step S702, when facsimile data is received, it is determined whether the facsimile reception proxy function is set or canceled. If the facsimile reception proxy function is set, the received facsimile data is stored in the storage unit 24 (S706).

If the facsimile proxy reception function is not set (S702), the slave unit PS is connected via the radio line RL.
1 is called (S703). If the handset PS1 does not respond, it will be called many times.

When the slave unit PS1 responds (S704), the master unit CS1 sends the slave unit PS1 via the reception state monitoring means 21.
The facsimile data is transmitted to No. 1 (S705).

In the above embodiment, the master unit sets the reception level threshold value from the slave unit. However, the master unit may set the reception level threshold value. In this case, a plurality of reception level thresholds may be registered in the master unit in advance, and the user may select one of them.
