Description

DETAILED DESCRIPTION OF THE INVENTION Object of the Invention (Industrial field of application) The present invention is directed to a case where a plurality of wireless connection devices are connected to a wireless line control device, and a wireless telephone within a predetermined range of the wireless connection device is a station. The present invention relates to a wireless telephone system capable of making a call with a line.

(Prior Art) Conventionally, in such a radio telephone system, the radio network controller periodically sends a notification instruction signal to the radio connection device to register the radio connection device that can be used by the radio telephone, and the radio connection is received. When the device sends out a notification signal within a predetermined range and a wireless telephone within the predetermined range responds, the wireless connection device is registered as a connectable wireless connection device of this wireless telephone.

When the wireless telephone receives the notification signal issued at a fixed period, but does not receive the notification signal from the wireless connection device within a fixed time and receives the notification signal from another wireless connection device, the wireless telephone sets the zone ( It is considered that the wireless connection device has moved within a predetermined communication range), and a new wireless connection device is registered as a wireless connection device of this wireless telephone.

However, in the above-mentioned wireless telephone system, when the wireless line control device issues a notification instruction signal to the wireless connection device, the notification instruction signal is sent to the wireless telephone if this wireless connection device is used for a call. Since there was no wireless phone, unnecessary location registration was sometimes performed even though the wireless phone did not move to another zone.

(Problems to be Solved by the Invention) In such a conventional wireless telephone system, when the wireless connection device is used for a call, unnecessary location registration is performed even if the wireless telephone does not move to a zone. There was a problem that it was done.

The present invention has been made in view of the above problems, and an object of the present invention is to perform position registration in which a wireless telephone is not required even when a notification instruction signal is sent when the wireless connection device is used for talking. To provide a wireless telephone system that does not occur.

[Structure of Invention]

(Means for Solving the Problems) In order to achieve the above-mentioned object, the present invention provides that the wireless line control device performs a steady operation when the wireless connection device is in a call when it receives the notification instruction signal. The notification instruction signal is issued at a timing different from that of the notification instruction signal.

(Operation) When the wireless connection device is in a call when it receives the notification instruction signal, the notification instruction signal is promptly sent after the call ends, and the notification signal is issued in response to the notification instruction signal. The wireless telephone confirms that there is no zone movement by this notification signal. Therefore, unnecessary position registration is not performed even when the wireless connection device is in a call.

Embodiment An embodiment of the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a wireless telephone system according to an embodiment of the present invention. As shown in the figure, this wireless telephone system includes a plurality of wireless connection devices in the wireless line control device 1.
81, 82, 83 are connected. The wireless line control device 1 includes a switch circuit 2, office line circuits 31, 32, 33, line circuits 41, 42, 43, a central control device 5, a storage device 6, and a storage unit 7. Local line circuit
31, 32 and 33 connect to the office lines 3A ₁ , 3A ₂ and 3A ₃ . The line circuits 41, 42, 43 are connected to the wireless connection devices 81, 82, 83. The switch circuit 2 switches and connects the line circuits 41, 42, 43 and the office line circuits 31, 32, 33. The central controller 5 controls the wireless line controller 1 in a centralized manner. The storage device 6 stores a program for driving the central controller 5. The storage unit 7 registers the location of each wireless telephone. The wireless connection devices 81, 82, 83 have predetermined zones 91, 92, 93, respectively, and are wirelessly connected to wireless telephones existing in the respective zones.

Next, the operation of this embodiment will be described. When the wireless line control device 1 sends a notification instruction signal to each of the wireless telephone devices 81, 82, 83 as shown in FIG. 2, it is checked whether or not the wireless connection device is busy (in use) (step 101). ). For example, when the wireless connection devices 81, 82 are not in use, a notification instruction signal is sent to the wireless connection devices 81, 82 (step 102). If the wireless connection device 83 is in use, this wireless connection device 83
Is stored in the storage unit 7 (step 103). That is, as shown in FIG. 3, the storage unit 7 stores the number of the wireless connection device that could not send the notification instruction signal.

When the wireless connection device 83 ends the call, the wireless line control device 1 searches the storage unit 7 as shown in FIG. 4 (step 201),
It is determined whether or not the corresponding wireless connection device is registered (step 202). In the case of this embodiment, since the wireless connection circuit 83 is registered, a notification instruction signal is sent to this wireless connection device 83 (step 203).

FIG. 5 shows the timing at which the radio network controller sends a notification instruction signal. The steady notification instruction signal is periodically issued and the notification instruction signal to the wireless connection device 81 is issued.
181 is issued, and after a certain period of time, a notification instruction signal 182 is issued to the wireless connection device 82. Similarly, a notification instruction signal is issued to each wireless connection device. The timing indicated by the dotted arrow in the figure is the generation timing of the notification instruction signal for preventing omission. For example, after the call is terminated by the wireless connection device 83, a notification instruction signal for preventing omission is issued at the closest timing at the end of the call.

When the notification instruction signal is sent to the wireless connection devices 81, 82, 83, the wireless connection devices 81, 82, 83 respectively send the notification signals into the zones 91, 92, 93. Upon receiving this notification signal and confirming the zone movement, the wireless telephone (for example, the wireless telephone 10B) in each zone issues a response signal, and this response signal is sent to the wireless line control device 1 via the wireless connection device 81. To be Then, the wireless line control device 1 registers in the storage unit 7 that the wireless connection device 81 to which the wireless telephone 10 can be connected is the wireless connection device 81.

As described above, in the present embodiment, when the wireless connection device is in use when the notification instruction signal is sent, the notification instruction signal for preventing omission is sent immediately after the end of use, so unnecessary location registration of the wireless telephone is performed. Can be prevented.

〔The invention's effect〕

As described in detail above, according to the present invention, it is possible to prevent unnecessary location registration of a wireless telephone even if a notification instruction signal is sent when the wireless connection device is used for a call. .
