DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention is used for a radio paging system. The present invention particularly relates to a time-designated wireless paging system capable of calling a called party at a time designated by a caller, and an apparatus therefor.

[0002]

2. Description of the Related Art Conventionally, as a method of designating a time at which a called party is called in a wireless calling system, a calling signal is transmitted by a wireless calling device at a time designated by a caller to call a portable wireless calling terminal. There was a proposal. As such a method, for example, Japanese Patent Application Laid-Open Nos. 61-218248 and 3-32146 disclose such methods.

[0003]

However, in the current radio paging system, the radio transmission capacity per unit time is limited by the allocation of the radio resources, and if a large number of paging requests are concentrated at the same time, However, there is a problem that the call cannot be processed within the designated time, and the time of the call is gradually delayed, and there is a problem that the receiver's wireless call receiver cannot be sounded at the time designated by the caller. Further, even if a call signal is transmitted at a time designated by the above-described wireless paging apparatus, even if the designated time call is preferentially called, if a large number of call requests are concentrated at the same time, However, since other call requests are kept waiting, there is a problem that limited wireless resources cannot be effectively used.

According to the present invention, when a call time is designated, the call designated time information is transmitted first, and if the called party is notified at the time designated by the received radio call receiver, the designated time is designated. It is not necessary to send a call signal over the wireless line at the time of the call, and in the current wireless call system that has only a limited wireless transmission capacity per unit time, the call is transmitted even if the wireless traffic is tight. At the time specified by the receiver, the receiver's radio paging receiver can be sounded,
It is an object of the present invention to provide a radio paging system capable of effectively utilizing radio traffic by transmitting a paging signal to a radio paging receiver before a paging time.

[0005]

SUMMARY OF THE INVENTION A first aspect of the present invention is as follows.
A paging time designated paging method, in which a paging signal including information for identifying a portable radio terminal is transmitted from a paging apparatus to call the paging terminal, the paging signal is transmitted to the paging terminal. The wireless paging terminal includes information for designating a ringing time, and the wireless paging terminal includes means for performing a ringing operation based on the received information on the ringing designation time. As a result, concentration of wireless traffic can be reduced and effective use can be achieved.

The message information area for transmitting the call signal to the portable radio terminal preferably includes an identifier area indicating that the service is a call time specification service and an information area of a call specification time following the identifier area. With such a configuration of the call signal, the call time designation information can be transmitted to the portable wireless terminal using the message information area, and the portable wireless terminal can extract the call designated time information.

A second aspect of the present invention is a radio paging receiver used in the radio paging system, wherein a means for recognizing information of a designated paging time in a paging signal and a time of a built-in clock are set as the time. Means for performing a sounding operation when the designated time has elapsed when the designated time has been reached or received. As a result, it is possible to provide a radio call receiver that makes a call at a designated time.

[0008] A third aspect of the present invention is a radio paging apparatus used in this radio paging system, which includes a call accepting means for accepting a call with a designated call time from a caller; Registration permission determining means for managing the reserved call amount accumulated at the time and determining whether registration of the received call time designation is possible, and a call signal for the call registered by the registration permission determining means. And a means for inserting the designated call time information into the information and transmitting the information to complete the wireless call processing before the designated time. Thus, it is possible to provide a wireless paging apparatus that performs reservation registration of a call with a designated call time and sends a call signal by the designated call time.

[0009]

In the present radio paging system, since the radio transmission capacity per unit time is limited, the maximum transmission capacity that can be registered and reserved as a time-specified call per unit time is determined in advance. According to this determined maximum transmission capacity,
When the wireless paging device receives the registration of the time-specified call, the registration is performed so that the sum of the previously reserved amount and the amount to be received does not exceed the maximum transmission capacity that can be registered. Allow

[0010] Thus, when calls are to be concentrated at the same time, the radio paging apparatus which is performing traffic management gives rejection or change of the call time to the caller at the time of reception and provides guidance such as voice to the caller. So that it will not accept reservations that cannot be transmitted in time.

[0011] The radio paging apparatus transmits a call signal including a message area containing an identifier indicating that the call time has been designated and the call designation time information before the designated call time.
When the portable radio receiver receives the call signal and determines that the call time is designated, the portable radio receiver performs a ringing operation when the clock in the portable radio receiver reaches the designated time according to the information of the designated call time. Indicates that the called party called. Also, a message transmitted subsequent to the designated call time information is displayed.

[0012] As a result, the calling process on the wireless line is terminated before the designated time for performing the ringing operation, so that the wireless traffic can be effectively used.

[0013]

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

FIG. 1 is a diagram showing a configuration of a radio paging system according to an embodiment of the present invention, and mainly shows a configuration of a radio paging apparatus.

In this embodiment, a radio paging apparatus 2 which receives a radio call from a public communication network 1 and forms a call signal.
And a transmitting device 5 for transmitting a radio paging signal, a radio transmitter 4 for transmitting a radio paging signal, and a transmitting antenna 5, and a radio paging receiver 6 for receiving the radio paging signal. It is a configuration for receiving a call signal for calling a machine.

In such a radio paging system, as a feature of the present invention, the paging signal transmitted from the radio paging apparatus 2 includes information for specifying the time at which the radio paging receiver 6 sounds, and The receiver 6 includes means for performing a sounding operation based on the received information on the designated call time.

Here, the radio pager 2 has a call accepting section 21 as a call accepting means for accepting a call with a designated call time from a caller, and a call reservation amount accumulated at the time of accepting the call. The traffic management unit 22, the memory unit 24, and the traffic management unit 22, the memory unit 24 permit and register the registration as a registration permission determination unit that determines whether registration of the received call time designation is possible. The function of the timer unit 23 for the called call
A data transmitting unit 25 is provided as means for inserting and designating calling time information into a calling signal and completing the wireless calling process before the designated time.

The radio paging receiver 6 includes means for recognizing the information of the designated call time in the call signal, and sets the designated time when the time of the built-in clock has reached or received the designated call time. As a means for performing a sounding operation when the time has elapsed, a central control unit 63, a memory unit 64, a timer unit 65, a speaker unit 66, and a message display unit 67 are provided.

Next, a paging operation in the radio paging system of this embodiment will be described.

First, the operation of the radio pager 2 will be described.

A calling call arriving via the public communication network 1 is:
The call is accepted by the call accepting unit 21, and is passed to the traffic managing unit 22 when the call can be accepted. Traffic management unit 2
Reference numeral 2 denotes a paging call in which the time reservation can be registered by managing the reserved call amount stored in the memory unit 24. Register data such as time. Then, the traffic management unit 22 refers to the time of the timer unit 23, reads out the call data whose wireless transmission time has come from the call data of the registered call from the memory unit 24, and reads out the data transmission unit 2
Pass to 5. The data transmitting unit 25 constructs a call signal format in which an identifier for specifying a call time and call-specified time information are inserted into radio information for a call that has reached a radio transmission time, and transmits the signal to the encoding device 3. The encoding device 3 encodes the radio paging data into a radio signal. The coded radio call signal is amplified by the radio transmitter 4 and transmitted from the transmission antenna 5.

The processing inside the radio pager 2 that has received the radio page information via the public communication network 1 is roughly classified into two processes, data registration and data transmission.

First, in the data registration, it is determined whether or not it is possible to accept a call at a designated call time while referring to the data registered and reserved. If possible, the call is registered. In this case, rejection of reception or prompting for time change by guidance is performed. If the call data can be registered, the traffic management unit 22
Is referred to, and if there is a vacancy in the wireless transmission capacity before the designated time, new registration is accepted, and the wireless transmission time, that is, the wireless transmission from the wireless transmitter 4 to the wireless paging receiver 6 is stored in the memory unit 24. The data of the signal transmission time, the call designation time, and the transmission message are stored.

The operation of registering the call data will be described in detail with reference to FIG.

This example is an example in which a reservation call table for registering call data is provided in the memory unit 24. The amount of this reservation can be up to 60% of the transmission capacity per unit time of the radio system used. The time at which the wireless signal is actually transmitted by the registered call reservation, that is, the wireless transmission time, is from 0 minutes to 10 minutes before the designated call time.

As shown in FIG. 2A, the call data is registered in the reservation call table in the order of the time in which the call for which the call time is specified has the threshold value of 60% of the wireless maximum transmission capacity. Here, a white frame indicates one of the registered call reservation calls.

Here, it is assumed that there is an X-bit call with a call designation time of 10:00. Call receiving unit 21
, The traffic management unit 22 checks the reserved call table in the memory unit 24, and checks the reservation call table from 9:50 to 10:00.
It is determined whether a call reserved for X bits can be registered up to minutes. In the case of FIG. 2 (b), there is a capacity to register a call reserved for X bits, and the call reserved call is registered at that time, with that time as the radio transmission time.
In the case of FIG. 2 (c), there is a Y-bit call whose call designation time is 10:00, and there is no capacity corresponding to the Y bit before the call designation time 10:00. The registration of the call reservation call cannot be accepted, and the call accepting unit 21 provides guidance such as rejection of acceptance or prompting the caller to change the call time.

In the data transmission operation, the traffic management unit 22 uses the timer function and the clock function of the timer unit 23 to
The wireless transmission time of the call data registered in the memory unit 24 is checked, and when the time comes, the call data is passed to the data transmission unit 25. The data transmitting unit 25 transfers the paging data to the encoding device 3, and the encoding device 3 encodes the signal into a radio paging signal and transmits the radio paging signal via the radio transmitter 4 and the transmitting antenna 5.

FIG. 3 shows the internal configuration of the radio paging receiver 6. The radio paging receiver 6 includes a reception antenna 61 for receiving a radio paging signal, and a reception antenna 61 for receiving the radio paging signal. Receiving unit 62 which is connected and amplifies a radio signal
And a central control unit 63 that analyzes the received radio signal and performs processing according to the content thereof, a memory unit 64 that stores the received data, and a timer function and a clock function that operate in conjunction with the operation of the central control unit 63. Timer unit 65 and a speaker unit 66 that performs a sounding operation for notifying that a call has been made.
And a message display section 67 for displaying a call message.

FIG. 4 shows the format of a radio paging signal transmitted in this embodiment.

The radio paging signal includes a synchronization signal for synchronizing with a receiver when performing radio communication, a radio address signal which is information designating a radio paging receiver for performing paging, and a call partner. And a message signal in which information to be notified is written. In the radio paging signal of this embodiment, this message signal portion is divided into a service identifier, service data, and message data as shown in FIG. The information is composed of designated time data and message data to be transmitted to the receiver as necessary information. This service identifier is information indicating which service is the content of the message signal, and the number of bits used for this can be set freely according to the number of services provided by the service provider. is there. When used as service data for call designation time information, 19 bits are used as the call designation time information, for example, 6 bits for day designation, 6 bits for hour designation, and 7 bits for minute designation. These data lengths can be changed according to the service contents.

When the paging receiver 6 receives a paging signal in which paging time designation information is included in the message signal portion, the following processing is performed.

Receiving section 62 receives a paging reservation radio paging signal via receiving antenna section 61, and then passes the received data to central control section 63. When the central control unit 63 determines that the call is a time-specified call by looking at the service identifier in the data, the central control unit 63 extracts call-specified time information (service data) in the data without immediately proceeding to the process of sounding the sound, and After setting the time to 65, the data is stored in the memory unit 64. Further, at the designated time, the timer unit 65 is activated and notifies the central control unit 63 that the designated time has come. In response to this, the central control unit 63 again retrieves the stored data from the memory unit 64, performs an operation for sounding the speaker unit 66, and displays message data to be displayed on the message display unit 67 when there is message data to be displayed. .

[0034]

According to the present invention, once a caller accumulates a time-specified calling call in the radio-calling device, the radio-calling device can receive the same-time-specified calling even if the same time is specified.
Since the information of the designated call time is transmitted to the portable wireless receiver before the designated call time, the call can be performed without delaying the designated time.

Further, according to the method of the present invention, even if calls are concentrated in a certain time zone, a paging time is specified first and a radio paging signal is transmitted. Since the transmission process can be performed, wireless traffic can be used effectively, and wireless resources can be used effectively.
Also, since calls that can be processed per radio frequency per day can be dispersed, it is possible to increase the call volume on average.
