Abstract

PURPOSE:To expand the talking connection area by storing an indentification code of plural radio connection devices in a radio telephone set, and sending a call signal continuously to plural radio connection devices stored at the time of calling. CONSTITUTION:A control section 22 of a radio telephone set 13 retrieves a RAM 23 to form a call signal including an identification code ID1 of a radio connection device 12a at first, then to form a call signal including an identification code ID2 of a radio connection device 12b, sending them continuously. The radio connection device 12a receiving the signal transmits a call reply signal including the identification code ID1 and the radio connection device 12b transmits a call reply signal including the identification code ID2 at a time retarded to evade collision. In a radiotelephony 13, an identification code collation section 24 applies identification code collation with a code stored in the RAM 23 and the telephone set 13 transmits an responding signal to the coincident ratio connection device only.

Description

Detailed Description of the Invention "Industrial Application Field" This invention consists of a plurality of wireless connection devices connected to a wired telephone line, and a plurality of wireless telephones connected to the wireless connection devices via a wireless line. Regarding the mobile radio telephone system,
In particular, when a wireless telephone makes a call, at least one wireless connecting device is selected from among a plurality of wireless connecting devices to enable connection control with the wireless telephone.

"Prior Art" FIG. 5 shows the configuration of a cordless telephone system, which is a conventional system of this type. Office line or extension line - which wired telephone line 11
It is composed of a wireless connection device 12 connected to the wireless telephone 1 and a wireless telephone 8!
3, each device has an identification code (or I )), and during connection control, each device sends out a control signal including the identification code necessary to determine the connection destination,
The device that receives this checks the identification codes, and if they match, a wireless line 14 is established between these devices, and no connection is established between the wireless connection device 12 and the wireless telephone 13 that have different identification codes.

Therefore, there is a drawback that a call connection can only be made in the service area belonging to one wireless connection device 12, and the connectable area is limited to a very narrow range.

An object of the present invention is to eliminate this drawback by enabling a wireless telephone to make a call connection with a plurality of wireless connection devices within a service area formed by a collection of wireless zones belonging to a plurality of wireless connection devices. To provide a mobile radio telephone with an expanded connectable area when making a call.

"Means for Solving the Problem" According to the present invention, the system is comprised of a plurality of wireless connection devices connected to a wired telephone line and a plurality of wireless telephones connected to the wireless connection device via the wireless line. , Each wireless telephone stores a plurality of identification codes individually assigned to the plurality of wireless connection devices.

When a wireless telephone makes a call to acquire one of the wireless connection devices, the call signal (-1) shall include consecutive individual identification codes of multiple wireless connection devices stored in the wireless telephone. and send it out.

Multiple wireless connection devices that have received the calling signal from the wireless telephone transmit the calling signal (--response signals to the included wireless connection devices according to their individual identification codes, so that the response signals are simultaneously transmitted to the wireless telephones. establishing the wireless line that allows two-way communication between the wireless telephone that made the call and at least one wireless connection device selected from the plurality of wireless connection devices; do.

In this way (- in this invention, the wireless telephone stores a plurality of identification codes of wireless connection devices to which a call can be connected, and when a call is connected, the wireless telephone continuously makes calls to each of the plurality of stored wireless connection devices). Since a call signal is sent out, a connection between a wireless telephone and a wireless connection device is possible in each service area of these wireless connection devices.

"Embodiment" FIG. 1 shows the configuration of an embodiment of the present invention. This is a case where a wireless connection device 12a with an identification code ID1 and a wireless connection device 12b with an identification code ID12 are provided, and other parts corresponding to those in FIG. 5 are given the same symbols. .

FIG. 2 shows an example of the configuration of the wireless telephone 13. As shown in FIG. Transmitter/receiver 21
is connected to a control section 22 that controls the entire radio telephone 13. It also stores the identification code of the wireless connection device.
AM23 and an identification code matching unit 24 that matches the identification code included in the signal sent from the wireless connection device are controlled by the control iI.
]] unit 22. FIG. 3 shows an example of storage in the RAM 23. In FIG. 1, address 1 contains the IDI corresponding to the wireless connection device 12a, and address 2 contains the IDI corresponding to the wireless connection device 12b.
ID2 corresponding to each is stored. Also the fourth
The figure shows the timing relationship from the sending of a calling signal by the wireless telephone 13 to the sending of a response signal by the wireless connection devices 12a and 12b. An example of the operation of the system of the present invention in the case where two types of identification codes of wireless connection devices are stored will be described in detail below with reference to the drawings.

When the wireless telephone 1 is in the positional relationship shown in Figure 1,
3 goes off-hook at time To in FIG.

When the control unit 22 detects this, it searches the RAM 23, reads out the stored identification code of the wireless connection device, and
First, a calling signal 31 including the identification code IDI of the wireless connection device 12a stored in address 1 is created, and a calling signal 32 including the identification code ID2 of the primary wireless connection device 12b is created.The call is made at time T1. The calling signal 32 is sent out, and the calling signal 32 is sent out continuously at time T2 when sending out the calling signal 32 is finished.

In the wireless connection device 12a that received the calling signal 31, the time T
3f 2 A call response signal 33 containing the identification code IDI of the own wireless connection device is sent out, and the wireless connection device 12b combines the call response signal 33 sent by the wireless connection device 12a and the call response signal 34 sent by itself. At time T4, which is delayed so as not to conflict with each other, the call response signal 34 containing the identification code 1]2 of the own wireless connection device is sent. The control unit 22 of the wireless telephone 13 that has received the call response signal 33, 34 detects the identification code included in the received signal, and checks the identification code collation unit 2.1.
The identification code is compared with the identification code stored in the RAM 23 at time T5 only for the wireless connection device that has sent out a call response signal that matches the identification code stored in the RAM 23.
In response, a response signal 35 is sent out. If you receive multiple call response signals, you may select the first signal you received, or
The one with the highest reception level may be selected. The following connection operation is the same as when using a normal cordless phone.

"Effects of the Invention" As explained above, according to the present invention, a wireless telephone stores the identification codes of a plurality of wireless connection devices, and when a single call is made, a call is made to the stored plurality of wireless connection devices. Since the signals are sent out continuously, the number of connectable wireless connection devices increases, which expands the call connection area when a call is made, and increases the connection rate as the number of wireless connection devices that connect and access increases. You can aim for the same goal.
