Description

[Detailed Description of the Invention] [Field of Industrial Application] The present invention relates to a means for writing control information such as an ID into a wireless telephone in a mobile communication system such as a multi-cordless telephone, and particularly relates to a means for writing control information such as an ID into a wireless telephone. This relates to a method that allows writing.

[Conventional technology]

Conventionally, there have been two methods for writing control information into a wireless telephone: a method in which a control information writing device is connected to the wireless telephone by wire, and a method in which the control information is written wirelessly from a wireless connection device in a single zone cordless telephone.

[Problem to be solved by the invention]

Among the methods of writing control information into conventional wireless telephones as described above, the former method of writing control information! ! In the case of the method of connecting the writing device and wireless telephone by wire, it is necessary to provide the wireless telephone with a connector for wired connection, which impairs the economic efficiency of the wireless telephone. The problem was that the connection was complicated and time-consuming.

On the other hand, in the latter wireless writing method, there was no method that could be applied to multiple zones.

SUMMARY OF THE INVENTION In view of these conventional problems, an object of the present invention is to provide a means for writing control information into a wireless telephone having a multi-zone configuration using a wireless method without using wires.

[Means to solve the problem]

According to the invention, the above-mentioned object is achieved by the means specified in the claims.

That is, the present invention provides a wireless line control device that controls the wireless line of a Kuma M connection area consisting of one or more wireless zones, and a wireless line control device that is connected to the wireless line control device via a transmission path and arranged in each wireless zone. Consists of a wireless connection device and a wireless telephone that is connected to these wireless connection devices via a wireless line and moves within the wireless connection area, and is necessary for call connection between the wireless connection device or radio line control device and the wireless telephone. In a system in which a wireless connection device transmits control information via radio as a control signal in response to an instruction from a wireless line controller, and a wireless telephone receives the control signal, the wireless telephone acquires the control information. The code is stored in advance, and the wireless line control device transmits the verification code together with the control information from a predetermined wireless connection device, and the wireless telephone stores the received verification code in its own memory. The received control information is temporarily stored when the matching code matches the verification code, and a response is returned to the wireless line control device, and the wireless line connection device stores the control information when there is a response signal from the wireless telephone. The radiotelephone data remote write method is such that the radiotelephone stores the control information in a non-volatile storage device when the instruction is sent and the radiotelephone receives the storage instruction.

[For production]

The present invention provides a mobile communication system with a multi-zone configuration.
In order to wirelessly write control information to a wireless telephone, the following operations are performed using the above-mentioned means.

That is, the radio line control device controls the control information signal to be transmitted only from the pre-selected radio connection device. The wireless connection device transmits a control information signal according to instructions from the wireless line control device. A verification code used to identify whether a received signal is control information that should be written is input and stored in advance in the wireless telephone, and the verification code and the received verification code are stored in advance. The control information is temporarily stored only when they match.

Further, in order to prevent malfunctions due to influences from other systems or errors in signals during transmission, confirmation is performed by sending and receiving response signals and storage instruction signals between the radio telephone and the radio line control device.

The wireless telephone first receives the storage instruction signal and then stores the previously stored control information in a non-volatile storage device.

As shown in the figure, in this example, the storage instruction signal includes a preamble 61, a frame synchronization 62, a storage instruction 63, and a verification code 64.

Like the verification code 54, the verification code 64 may be the same as the verification code 44 in FIG. 4, or may be control information or an appropriate part thereof.

FIG. 7 is a diagram showing an example of a procedure for writing control information such as an ID from the radio line control device 12 to the radio telephone 16 using radio.

In the figure, the wireless line control side 12 selects the wireless connection device 14 in advance and then performs writing. Although this is a multi-zone configuration, the wireless line control side 12
Since no control information is written in the , the location of which wireless zone it is in is not registered in the wireless line connection device 12 .

Therefore, in advance, the radio line control device 12
This is because it is necessary to tell the user which bear #l connection device should be used for writing. Although it is conceivable to send control information signals in all wireless zones, this method puts pressure on control channel traffic.

It is necessary to input the verification code 44 into the wireless telephone 16 in advance. Since this is a multi-zone configuration, control information is often automatically written to multiple radio telephones one after another, but in this case, the same control information can be written to different radio telephones by a matching code that distinguishes each radio telephone. This is to prevent the data from being written. The verification code may be written into the radio telephone at the time of manufacture or immediately before the control information is written.

After entering the verification code 44, the wireless line controller!
12 sends a control information signal to the wireless connection device 14.

When the wireless connection device 14 receives the control information signal, it sends it to the wireless telephone 16 via the wireless line 15.

Upon receiving the control information signal, the wireless telephone 8116 stores the control information 43 in the temporary storage device 37 if the verification codes 44 match. Thereafter, a response signal is returned to the wireless connection device 14. If the verification codes 44 do not match, or if the control information is already stored in the nonvolatile storage device 38, this signal is ignored.

When the wireless connection device 14 receives the response signal, it sends the response signal to the wireless line control device 12.

The radio line control device 12 receives the response signal, and if the verification code 54 matches the verification code 44, sends a storage instruction signal to the wireless connection device 14.

Note that the verification code 54 does not necessarily have to be the same code as the verification code 44; for example, the same effect can be obtained even if it is the number of a wireless telephone in the control information. If the verification codes do not match, the radio line control device 12 ignores the response signal.

The wireless connection device 14 sends a wireless line control wave r1112 ;I>
- If a storage instruction signal is received from the radio telephone 16, the storage instruction signal is sent to the wireless telephone 16.

The wireless telephone 16 receives the storage instruction signal and stores the verification code 6.
4 matches the verification code 54, -time storage device 3
The control information stored in 7 is stored in the nonvolatile storage device 38. In addition, -degree control information! 8 wireless telephone 8
! In order to prevent erroneous rewriting to 16, the fact that the control information has already been stored is stored in the nonvolatile storage device 38 in a format such as 7 lag.

When this flag is on, even if control information is received again, it can be ignored. Note that the verification code 64 is not necessarily the same as the verification code 54, and there is no need to use a code. The same effect can be obtained even if the information includes the number of an M-free telephone. If the verification codes do not match, wireless telephone W116 ignores the storage instruction signal.

When writing control information to multiple wireless telephones 16, if you enter the verification code 44 into the wireless telephones in advance, the wireless telephones 8!16 will be automatically written one after another from the radio line control wave W112.
Control information can be written to.

〔Effect of the invention〕

As described above, according to the present invention, control information such as an ID can be written into a wireless telephone using wireless communication in a multi-zone configuration.

This eliminates the need for a connector for wired #l connection, which was conventionally necessary, making the wireless telephone economical.

In addition, in the past, each writing device and wireless telephone had to be connected by wire, making handling complicated and requiring a long time to process; however, with the present invention, this can be done wirelessly. This has the advantage that control information can be written easily and quickly by typing.
