Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a system cordless telephone system, and more particularly, to a system cordless telephone system which is designed to save the battery consumption of a handset.

[0002]

2. Description of the Related Art A system cordless telephone system is shown in FIG.
As shown in FIG. 3, the key telephone main unit 1 and a plurality of cordless telephone units 2 and 3 connected to the key telephone main unit 1 are configured. A wired ordinary telephone 4 can be further connected to the key telephone main unit 1.

The base unit 2 of each cordless telephone device wiredly connected to the key telephone main unit 1 has a data communication function similar to that of a key telephone, and is installed at an appropriate place on the premises to form a wireless zone. , And controls the wireless connection with the handset 3 and holds the call. Since one master device 2 can hold one slave device 3 for communication, when a simultaneous call is required in the same area, a plurality of master devices 2 are installed in the area, and those master devices Master group by machine
G1, G2 and G3 are formed. When the area is divided into several areas such as the first floor, the second floor, and the third floor, base unit groups G1, G2, and G3 are installed in each area.

The slaves 3 are prepared according to the number of the masters 2, and are installed in various places on the premises like general extension telephones. Since each is a low-power cordless telephone, a handset 3
Can move within a line-of-sight range of up to about 100 m and can be connected to any base unit 2.

These cordless handsets 3 can be operated by any one of the cordless handsets 2 by the position registration management function of the system cordless telephone device.
Whether it belongs to the service area of is managed.

Position registration is set in advance for the slave unit 3. This location registration setting is performed by storing the location registration data notified from one parent device 2 of the parent device groups G1, G2, and G3 to which the child device 3 belongs in the memory (ID ROM) of the child device 3. Be done. When making a call from the child device 3, the control station described later in this parent device group is accessed.

The location registration data is also notified from the base unit 2 to the key telephone main unit 1 and stored in the memory thereof.
At the time of incoming connection from the central office line, the master unit 2 for calling the slave unit 3 is determined by this data.

Further, the location registration data needs to be updated at any time as the mobile device 3 moves. In this system, the master unit 2 periodically outputs a position registration instruction request to the slave units 3 within its own service area at intervals of 1 to 3 minutes. If the stored location registration data is changed, the location registration data is updated (automatic location registration). It is also possible to output a position registration instruction request from the handset 3 by button operation, and receive a response signal from the base unit 2 to update (manual position registration). In either case, the data on the key telephone main unit 1 side is updated at the same time.

Since a large number of base units 2 are installed in the same wireless area, when each base unit 2 performs a position registration operation, the control channel is exclusively used for the position registration operation, and transmission / reception is performed. Problems occur when connecting incoming calls. In order to avoid this, one master unit in each master group G1, G2, G3 serves as a control station, and only that control station performs the position registration operation. Further, when a call is established between the master unit that has become the control station and the slave unit, another master unit functions as the control station instead.

Since the cordless telephone device slave unit uses a storage battery as a power source, it is necessary to reduce current consumption as much as possible.
Therefore, the slave unit 3 saves power by an intermittent operation during standby. In this intermittent operation, the receiving system of the RF circuit (radio section) is energized for an extremely short time to perform carrier sensing (determination of the presence or absence of received radio waves) of the control channel, and as a result of this carrier sense When there is no power supply, the operation of turning off the power supply to the receiving system and energizing the control unit and the like to the minimum necessary is periodically repeated, and the longer the power supply is turned off, the more the storage battery consumption is suppressed.

On the other hand, however, if the off time is too long, the response may be delayed or cannot be received when the incoming signal or the like is received. Therefore, it is necessary to set the time to an optimum value.

Such an intermittent operation called battery saving is also performed in the handset 3 of the conventional system cordless telephone device, and the battery consumption during standby is suppressed as much as possible to enable long-term use. There is.

[0013]

However, in the conventional system cordless telephone device, the battery saving cycle of the handset cannot be changed because it is set in advance, so that it can be used in standby mode regardless of the amount of traffic. Battery consumption is the same at any time. for that reason,
Even in a time zone with a low traffic volume such as late at night, the same electric power as in the daytime is consumed, and the battery is not used efficiently.

The present invention solves the problems of such a conventional system cordless telephone device, and sets the battery saving cycle of the slave unit according to the traffic volume of each time zone of the user. It is an object of the present invention to provide a system cordless telephone device that enables the use of the battery and thereby enhances the battery usage efficiency.

[0015]

Therefore, in the present invention, a system including a key telephone main unit, a master unit wiredly connected to the key telephone main unit, and a slave unit capable of wireless connection to the master unit. In the cordless telephone device, a storage unit that stores a plurality of types of periodic patterns regarding battery saving in the slave unit, and a control unit that controls the battery saving during standby by the types of periodic patterns notified from the key telephone main unit. The key telephone main device is provided with a registration means for setting and registering the relationship between the time and the type of the periodic pattern, and a notification means for notifying the handset of the type of the periodic pattern corresponding to each time based on the relationship. It is provided.

[0016]

Therefore, the cycle pattern of turning on and off the battery saving in the slave unit is controlled based on the relationship between the time and the type of the cycle pattern, which is preset and registered in the key telephone main unit. Therefore, by taking into account the traffic volume of each time zone of the user, by setting and registering the cycle pattern of the long off-time in the time zone where the traffic volume is small, it is possible to improve the usage efficiency of the battery of the slave unit.
