Abstract

PURPOSE:To limit no-reception of control signals due to fading only to the no- reception of each period by transmitting continuously the incoming control signals to be transmitted to a mobile station from a base station via a radio circuit synchronously with a call signal given from a wire telephone circuit. CONSTITUTION:The fall of a call signal is detected by a call signal detecting circuit 11 of a base station 1. Thus a control circuit 13 stops the transmission of the bell ring signal. In this case, a mobile station 5 rings a bel until the next bell ring signal is received. If no signal is received by that time point when the next bell ring signal is received, a bell drive circuit 55 is controlled to stop quickly the ringing of a bell 56. As a result, the bell 56 of the station 5 is rung in the timing shown in a figure (c) and synchronously with a call signal shown by a figure (a). When the bell ring signal is transmitted and the bell ring signal is not received due to the fading, etc. at a point B1 of a figure (b), the station 5 detects the bell ring signal to be transmitted after a period and rings the bell 56.

FIG. 1 is a block diagram showing a schematic configuration of a radio f which employs a multi-channel access method. In FIG. 781, the base station 1 of the wireless receiving device includes a call U-1 signal detection circuit 11,
The hybrid circuit 12.11i11f is composed of an immediate grounder 13, a variable 9-tone circuit [4, a transmitter I5, a receiver]-6, and is connected to an external exchange base via a circuit L8. On the other hand, the mobile station 5 of the wireless 4-speaker device includes a father's device 51, a speaker 52, a modulation/demodulation circuit 53, a digital output circuit 54, a bell drive circuit 55, a bell 56, a catfish 57, and so on. It consists of a microphone 58 and a microphone 58. In addition, in FIG. 1, 6 shows an example in which the mobile station is in its infancy due to ``tij''.Base station 1
Then, when the call signal 1 signal from the exchange q-Aph is released in the call signal construction circuit 11, in order to notify the mobile station 5 of the call, the 1lIl11 output circuit 13, the f return circuit 1Raku 14,
A fixed digital signal of I-) is transmitted and received between the transmitter 15, the receiver i51 of the mobile station 5, the modulation/demodulation circuit 53.1t71J1 and the previous circuit 54, and In between, perform the prescribed shoulderless times1. Establish. Thereafter, the base station 1 sends out to the mobile station 5 via the above-mentioned line the digital signal f which causes the mobile station 5 to perform the blasphemy display operation. Here base station 1
The Bell 1IIS of the mobile station 5 is generally connected in parallel with other exchanges (not shown).
It is preferable that the call is the same as the call of the Bell 1IIS of the exchange. Therefore, conventionally, when the mobile station 5 performs a bell ringing synchronized with the discharge sound from the exchange 1) 11, the base station 1 uses the

Oitake is continued until h reaches 1 ramie of 11.

[Four points of K group technology] However, the rise of 1 degree between base station 1 and mobile station 5 does not necessarily mean that the bell will ring at the bottom, and if fading occurs, mobile station 5 will ring the bell at number 1g. and bell ringing stop 48
You may not be able to receive the signal. The above-mentioned conventional radio "f"
According to the 1g signal transmission method of the T-talk device, for example, fading occurs at the timing shown in FIG. The state will be as follows. Similarly, if the bell ringing @ signal cannot be received at 4pm in the evening, the ringing of the bell will stop, and the ringing of the bells of the mobile station 5 and the ringing of the mobile station 5, which are connected in parallel with the base station 1, will not match. mosquito,
There was a drawback that the ring tone sounded unnatural.

[Purpose of the Invention] The present invention 19J has been developed in view of this situation, and aims to reduce the influence of the control signal 1g at the mobile station due to fading of the electric field between the base station and the mobile station. Another object of the present invention is to provide a layer 1 to 1G transmission system for a wireless 4-talk device that can ring the bells of exchanges and mobile stations in a relatively small number of seconds.

[Summary of the invention]

Accordingly, in the present invention, in response to a caller's message from a mobile phone line, there is a method for causing a 11 display operation to be sent from a base station to a mobile station via a wireless station.
1tilJ control signal from μ・Y from the wired d talk line.
I try to send out continuously in synchronization with Dashi Hakushun.

[Embodiments of the Invention] Examples of the present invention will be described in detail below with reference to the drawings. FIGS. 3(a) to 3(C) are time charts of each signal when implementing the observation signal sending method of the wireless telephone device according to the present invention. 3. Based on the output signal from the exchange ph shown in Figure 3 (a), the i reception of PJr constant control number 4g is performed between the base station 1 and mobile station 5 on the control channel, and there is no interference between the two stations. Establish. In the wired base station 1, the control circuit 13 drives the post-modulation circuit 14, and uses nT constant modulation to create a bell ringing signal with a cycle sufficiently shorter than the cycle of the ringing signal of the exchange ph. (See FIG. 3(b)) Next, in synchronization with the rising edge of the call 4WM applied to the transmitter 15 via the λ hybrid circuit 1Nr11, FIG. 3(b)
) is sent to the mobile station 5 from the sending signal channel 15 using the signal channel. Continue to base station
Then, the call number detection circuit 1 monitors this call number 1g, and continuously sends out the Pjf fixed periodic bell ringing signal to the mobile station 5 while the call signal is on. On the other hand, when the mobile station 5 receives this bell ringing signal, the control circuit 54
1tilI911 drives the bell drive circuit 55 to ring the bell 56. Then, the next period of bell ringing 4g
Continue this operation until the time when the signal will be received.

When the falling edge of the paging signal is detected by the paging signal detection circuit 11 of the base station 1, the control circuit 13 stops sending out the bell ringing signal. At this time, the mobile station 5 continues to ring the bell until the time when the next bell ringing signal will be received.

When the next bell ringing signal is found to have not been received even when the time when the next bell ringing signal is expected to be received, the bell drive circuit 55 is controlled to immediately stop the ringing of the bell 56. When the call number 1g falls, no tlilJ control signal such as a bell ringing stop signal is sent from the base station 1 to the mobile station 5.

As a result, the bell 56 of the mobile station 5 is rung in synchronization with the caller's bow shown in the third section (a) at the timing shown in FIG. 3(C). When transmitting the first bell ringing number by the method described above, for example, as shown in FIG. The bell 56 can be ringed by detecting the ringing number 1g that should be sent out. Mabuko,
'At the 3rd B2 point, the fading of Mr. CII3J occurred; however, the reception of the Pell 1i13 assistance information signal for ``-Call'' was discontinued, but the bell ringing signal for the next cycle Iυ was not received. Uke 4
g, and since this period is well known, mobile station 1 can perform 1.g when the bell 1 is stepped. It is possible to use a normal caller/21 with a small number of calls. In addition, the base station 1 does not use the bell 14iω1 stoppage 1g signal, and the mobile 7i, j5 detects the stopping of the transmission 1 of the bell 1kalph motion 1d- signal, and the C bell liii! m
2 There is something that stops C, so I will go to the fading temple-C
The bell never stops ringing.

〔Effect of the invention〕

The situation has been clarified as follows.
According to the G13 transmission method, the bell ringing signal is sent out continuously in the same manner as the ringing signal 1g from the temple, and the mobile station receives the bell ringing signal of the next cycle. 71. The bell rings until the time when the bell is expected to be received, and the bell ringing is stopped as soon as the 1st bell ringing IIh polarization is not received. The non-reception of the signal also varies from cycle to cycle. Just by receiving the signal, it is possible to perform one movement in synchronization with the neighboring No. 8, and at the same time, the unnatural ringing of the bell 1 (! It has the excellent effect of preventing
