Abstract

PURPOSE:To allow a caller to confirm the state of the reception side by providing a state informing means informing a required state selected by the reception side or a selected call display mode to the caller side when a paging receiver receives a call signal. CONSTITUTION:In calling the paging receiver 16, a telephone set 1 dials a paging call identification number, an object receiver number and an urgency number in this order. The signals through an exchange station 2 reach a paging sending station 6 and are sent from nan antenna 5. The modulation wave received by an antenna 7 is given to a decoder 9, where a call number in an input code string and the own call number are detected for the coincidence, and the extracted urgency signal and a required state signal for a state setting circuit 10 are combined by a combination discrimination circuit 11. As soon as the output of the circuit 11 switches a speaker 13, a display device 14 and a caller of a vibrator 15, the setting state of the circuit 10 is coded by an encoder 17, the result is sent from the antenna 7 via a sending section 18 and a transmission station 6 confirms the state of the reception state.

Description

DETAILED DESCRIPTION OF THE INVENTION [Field of Application of the Invention] The present invention relates to a paging receiver paging system, and particularly to a paging receiver paging system in which a paging display format can be selected.

[Background of the invention]

Conventionally, as a method of calling a paging receiver, a method is known that selects and controls depending on the urgency of the caller, such as busyness and the paging receiver's calling mode, as shown in Japanese Patent Laid-Open No. 58-81551.

However, depending on the condition of the receiving party, a particular type of paging may be required regardless of the urgency of the calling party, or in all but the most urgent cases. For example, an audible call method is inconvenient under any circumstances, such as during recording work, and an audible call method is inconvenient during a break or the like, even if the caller's level of urgency is low.
In some cases, it may be convenient to use all forms of invocation, such as visible and mobile. In the prior art described above, consideration was not given to such a state on the receiving side.

[Purpose of the invention]

An object of the present invention is to eliminate the drawbacks of the prior art and to ensure paging depending on the location and situation by selecting the paging form of the paging receiver depending on the urgency of the calling side and the state of the receiving side. The objective is to provide a highly flexible paging call method.

[Summary of the invention]

In order to achieve this object, the present invention determines and calls a paging form based on a combination of the state of a state switching circuit preset on the receiving side and a signal indicating the degree of urgency sent from the calling side. At the same time, the calling party is able to confirm the status of the receiving party by calling the status of the preset state switching circuit from the receiving party to the calling party.

[Embodiments of the invention]

Embodiments of the present invention will be described below with reference to the drawings.

FIG. 1 is a block diagram showing an embodiment of the paging receiver calling system according to the present invention, in which 1 is a telephone, 2 is a switching center, 6 is an encoder, 4 is a transmitting device, 5 is an antenna, 6
is a paging transmitting station, 7 is an antenna, 8 is a receiver, 9 is a decoder, 10 is a state setting circuit, 11 is a combination judgment circuit, 12 is a call switching circuit, 13 is a speaker, 14 is a display L/(, 15 is a A vibrator, 16 a paging receiver, 17 an encoder, 18 a transmitter, 19 a receiver, and 20 a decoder.

In the figure, a paging receiver (hereinafter referred to as receiver)
16, the calling side c) dials from the telephone 1 using the paging call identification number, the target receiver number, the emergency number, and the song of the emergency number. These numbers reaching the paging transmitting station 6 through the switching center 2 are encoded by the encoder 3 after adding a message if necessary.

FIG. 2 shows an example of an encoding system. In this specific example, a busy-switching method is used to reduce the average current usage of the receiver. Each receiver belongs to one of the 15 groups in which 20 seconds are divided, and receives only the time of the corresponding group. That is, each receiver operates for only about 14 seconds every 20 seconds. The time allocated to each group can accommodate a synchronization signal and up to eight selective call signals. The synchronization signal further comprises a pit synchronization signal, a frame synchronization signal, and a group designation number, and the calling signal comprises a calling number, a message, an urgency signal, and a check pit for error correction.

The encoder 3 generates a group designation number and a calling number for the corresponding receiver from the receiver number generated by dialing the telephone 1. The synchronization signal and the paging signal are amplified and modulated by the transmitter 4 and sent out from the antenna 5.

The receiving circuit of the receiver 16 operates only during the time of the group to which the receiver 16 corresponds. The modulated wave received by the antenna 7 is amplified and demodulated by the receiving section 8 to become a code, and is input to the decoder 9. The decoder 9 detects a match between the calling number in the input code string and its own calling number, and when this is detected, further extracts a code representing the degree of urgency. The combination determination circuit 11 combines this urgency code with the required status signal set in advance by the status setting circuit 10, and determines a paging form, for example, as shown in the next first FeK.

Table 1 However, S: speaker V: vibrator D = nib play output switch 12 selects the speaker 13, display 14, vibrator 15 according to the output of the combination determination circuit 11.
etc., and generates a calling signal or message.

Therefore, if the user of the receiver is in the middle of an important meeting, for example, by setting the necessity level of the status to 3 using the status setting circuit 10, it is possible to receive a particularly urgent call with an emergency level of 1. Otherwise, the meeting will not be interrupted, and even a call with an emergency level of 1 will not be noticed by others. Also, if you set the necessity level to 1 during a break, you will be able to notice most calls. Also, when you are engaged in recording work, if you disable audio, the speaker 13 will be used to call you to the chair.

At the same time, the state set by the state setting circuit 10 is encoded by the encoder 17, modulated and amplified by the transmitter 18, and then transmitted from the antenna 7. The timing of transmission is the next cycle of the corresponding group allocation period of the receiver, and the time when the own station's calling signal was received in the previous cycle (
This is the same time (FIG. 2(b')) as FIG. 2(b)). Therefore, the paging transmitting station 6 transmits the paging at the same time (Fig. 2 (b')) as the time when the paging was made in the previous cycle (Fig. 2 (b)).
)) K performs reception. Therefore, the transmissions from the paging transmitting station and multiple receivers do not overlap.

The modulated wave received by the antenna 5 of the paging transmitting station 6 is amplified and demodulated by the receiving device 19, and then the receiver state code is extracted by the decoder 20. The receiver status code is converted into a synthesized voice and transmitted to the calling party through the switching center 2) telephone set 1. If the receiver status code is not received at time (h) in FIG. 2, paging is sent. By performing this transmission and reception multiple times, the reliability of the call can be increased.

In this embodiment, when the receiver 16 receives a paging signal, the receiver status preset in the status setting circuit 10 is transmitted to the paging transmitting station 6. The paging form determined by the circuit 11 may be transmitted.

Furthermore, both the set state and the determined paging format may be transmitted.

Next, another embodiment will be described.

In FIG. 1, the caller uses the receiver 16
After confirming the status, dial the calling mode selection number if necessary. In the next cycle after receiving the receiver status, the paging transmitting station 6 adds a code indicating that it has called again to the first paging signal and transmits it. In the receiver 16, when the decoder 9 detects a code indicating re-calling in the received paging signal string, the state setting circuit 1
Regardless of the state of 0, the calling mode is selected according to the caller's selection and the user is called.

In this embodiment, it is possible to solve the inconvenience that the receiver user is not aware of the urgent situation in which he or she absolutely wants to make contact.

〔Effect of the invention〕

As explained above, according to the present invention, the call display format of the receiver can be appropriately selected depending on the urgency of the calling side and the status of the receiving side, and the status of the receiving side can be confirmed at the same time.
It is possible to provide a paging call system that can be freely carried by a receiver user regardless of location or situation, and has high call reliability.
