Abstract

PURPOSE:To originate a call without being late for designated time by transmitting the information of the calling designated time from a device for radio calling to a portable radio receiver before the calling designated time although there is a call designating the same time when a caller temporarily stores a call for time designating calling in a device for radio calling. CONSTITUTION:A call originated through a public communication network 1 is received by a calling receiving part 21 and led to a traffic managing part 22. The managing part 22 registers data such as the calling designated time or a transmissive message and the data of radio calling time on a memory part 24. While referring to the time of a timer part 23, the managing part 22 reads the call at the radio transmission time from the memory part 24 corresponding to the calling data of a registered call and dispatches it to a data transmitting part 25. The transmitting part 25 consists of a calling signal format by inserting the identifier of calling time designation and calling designated time information into the radio information of calling data at the radio transmission time and transmits them to an encoder 3. In this case, the device 3 encodes the data for radio calling to a signal for radio, and that signal is amplified and transmitted by a transmitter 4.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention is used in a radio paging system. The present invention particularly relates to a time-specified radio paging system capable of calling a called party at a time specified by a caller and a device therefor.

[0002]

2. Description of the Related Art Conventionally, as a method for designating a time for calling a called party in a radio calling method, a method for sending a calling signal by a radio calling device at a time designated by a caller to call a portable radio calling terminal. Was proposed. Such a method is proposed in, for example, JP-A-61-218248 and JP-A-3-32146.

[0003]

However, in the current radio paging system, the radio transmission capacity per unit time is limited due to the distribution of 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 specified time and the time of the call is gradually delayed, and there is a problem that the radio call receiver of the receiver cannot ring at the time specified by the caller. Further, even if the designated time calling is preferentially called when the calling signal is sent at the time specified by the wireless calling device side, if a large number of calling requests are concentrated at the same time, Since other call requests are put on hold, there is a problem that limited wireless resources cannot be effectively used.

According to the present invention, when the calling time is designated, the calling designated time information is transmitted first, and if the called party is notified at the time designated by the received radio paging receiver, the designated time is designated. Focusing on the fact that a ringing signal does not have to be sent over the wireless line at the ringing time, in the current wireless ringing system that has a limited wireless transmission capacity per unit time, even if the wireless traffic is tight Can ring the receiver's radio call receiver at the time specified by the person
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 the actual paging time.

[0005]

The first aspect of the present invention is to:
In a radio paging system for designating a paging time, a paging signal including information for identifying a portable radio terminal is transmitted from a radio paging device to call a portable radio paging terminal. It is characterized in that the wireless calling terminal includes means for performing a sounding operation based on the received information of the designated call time, including information for designating the time of ringing. As a result, the concentration of wireless traffic can be reduced and effective use can be achieved.

It is preferable that the message information area for transmitting the call signal to the portable wireless terminal includes an identifier area indicating that it is a call time designating service and an information area of the call designating time subsequent thereto. With such a configuration of the calling signal, the calling time designation information can be transmitted to the portable wireless terminal using the message information area, and the calling designated time information can be retrieved by the portable wireless terminal.

A second aspect of the present invention is a radio paging receiver used in this radio paging system, wherein the means for recognizing information of a designated paging time in a paging signal and the time of a built-in clock are the above-mentioned. And a means for performing a sounding operation when the designated time for calling is reached or when the designated time has elapsed when receiving the call. This makes it possible to provide a radio paging receiver that makes a paging at a designated time.

A third aspect of the present invention is a radio paging apparatus used in this radio paging system, which includes a paging acceptance means for accepting a paging call accompanied by a paging time designation from a caller, and a paging call receiving means for receiving the paging call. Registration permission determining means for managing the amount of call reservations accumulated at that time and determining whether or not the received call time designation can be registered, and a call signal for the call registered by the registration permission determining means. Means for inserting and calling out the designated call time information in the inside and completing the radio call processing before the designated time. As a result, it is possible to provide a radio paging device that performs reservation registration of a paging call accompanied by designation of a paging time and sends a paging signal by the designated paging 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 decided maximum transmission capacity,
When the wireless call device accepts the registration of the time-specified call, registration is performed so that the sum of the previously registered amount and the amount to be accepted will not exceed the maximum transmission capacity that can be registered and reserved. Allow

As a result, when calls are concentrated at the same time, the radio paging device that manages traffic gives a voice guidance or the like to the caller when rejecting or changing the paging time at the time of acceptance. To avoid accepting reservations that cannot be transmitted in time.

Before the designated call time, the radio paging device sends a call signal in which a message area includes an identifier indicating that the call time is designated and the designated call time information.
When the portable wireless receiver receives the ringing signal and determines that there is a designated ringing time, it makes a sounding operation when the clock in the portable wireless receiver reaches the designated time according to the information on the ringing designated time. Displays that the called party has called you. It also displays the message sent after the designated call time information.

As a result, the calling process on the wireless line is finished before the designated ringing time at which the ringing operation is performed, so that it is possible to effectively use the wireless traffic.

The configuration is such that a call signal for calling a machine is received.

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

Here, the radio paging apparatus 2 has a paging acceptance section 21 as a paging acceptance means for accepting a paging call accompanied by designation of a paging time from a caller, and a call reservation amount accumulated at that time when the paging call is accepted. The traffic management unit 22, the memory unit 24, and the traffic management unit 22 and the memory unit 24 permit the registration as registration permission determination means for determining whether or not the received call time designation can be registered. By the function of the timer unit 23 for the called call,
A data sending unit 25 is provided as a means for inserting and sending the designated call time information in the call signal and completing the wireless call process before the designated time.

Further, the radio paging receiver 6 recognizes the information of the designated call time in the call signal and the designated time when the time of the built-in clock reaches or receives the designated call time. 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 as means for performing a sounding operation when the time has elapsed.

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

First, the operation of the radio paging apparatus 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 if accepted, is passed to the traffic management unit 22. Traffic management unit 2
Reference numeral 2 denotes a radio call for managing the call reservation amount stored in the memory unit 24 and registering the time designation by registering the data such as the designated time of the call, the transmission message, and the time when the call data is transmitted. Register data such as time. Then, the traffic management unit 22 refers to the time of the timer unit 23 to read the call data of which the wireless transmission time has arrived from the registered call data of the call from the memory unit 24, and the data transmission unit 2
Pass to 5. The data sending unit 25 constructs a calling signal format in which the calling time designation identifier and the calling designation time information are inserted in the wireless information for the calling call when the wireless transmission time comes, and sends the calling signal format to the encoding device 3. The encoding device 3 encodes the radio call data into a radio signal. The coded radio call signal is amplified by the radio transmitter 4 and transmitted from the transmitting antenna 5.

The internal processing of the radio paging apparatus 2 which has received the radio paging information via the public communication network 1 is roughly classified into two processes, data registration and data transmission.

First, in data registration, it is judged whether or not a call call with a call time designated can be accepted with reference to the reserved data. If it is possible, the call call is registered. , Rejection of acceptance or guidance to change the time by guidance. When the call data can be registered, the traffic management unit 22 stores in the memory unit 24.
If the wireless transmission capacity before the designated time is available, the new registration is accepted by referring to the call data already registered in the wireless transmission time, that is, the wireless transmission time in the memory unit 24, that is, the wireless transmission from the wireless transmitter 4 to the wireless call receiver 6 The data of the time to send the signal, the designated time to call, and the transmission message are accumulated.

The call data registration operation will be described in detail with reference to FIG.

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

As shown in FIG. 2 (a), call data is registered in the reserved call table in order of time, with calls having call times designated as thresholds of 60% of the maximum wireless transmission capacity. Here, the white frame indicates one of the call reservation calls that have already been registered.

Here, it is assumed that there is an X-bit paging call having a designated paging time of 10 hours and 00 minutes. Call acceptance section 21
The traffic management unit 22 looks up the reserved call table in the memory unit 24 and receives the request from 9:50 to 10:00.
It is determined whether a call with a call reservation equivalent to X bits can be registered within the period of up to the minute. In the case of FIG. 2B, since there is a capacity capable of registering a call reservation call corresponding to X bits, the call reservation call is registered at that time as the wireless transmission time.
In the case of FIG. 2 (c), there is a Y-bit call that has a call-specified time of 10:00, and the capacity equivalent to the Y-bit is not present before the call-specified time of 10:00. Registration of a call reservation call cannot be accepted, and the call acceptance 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,
Looking at the wireless transmission time of the call data registered in the memory unit 24, when the time arrives, the call data is passed to the data transmission unit 25. The data sending unit 25 transfers the calling data to the coding device 3, and the coding device 3 codes the wireless calling signal and sends the wireless calling signal via the wireless transmitter 4 and the transmitting antenna 5.

FIG. 3 shows the internal structure of the radio paging receiver 6. The radio paging receiver 6 includes a receiving antenna section 61 for receiving a wireless paging signal and the receiving antenna section 61. A receiver 62 that is connected and amplifies a radio signal
And a central control unit 63 that analyzes the received wireless signal and performs processing according to the contents thereof, a memory unit 64 that stores the received data, and an operation of the central control unit 63, and operates a timer function and a clock function. The timer unit 65 having the speaker unit 66 and the speaker unit 66 performing a sounding operation for notifying that there is a call.
And a message display unit 67 for displaying a call message.

Next, FIG. 4 shows a radio paging signal format transmitted in this embodiment.

The radio call signal is a synchronization signal for synchronizing with a receiver when performing radio communication, a radio address signal which is information designating a radio call receiver for making a call, and a party for making a call. It consists of a message signal that contains the information you want to inform. In the wireless 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 required information includes designated time data and message data to be transmitted to the recipient. This service identifier is information indicating which service the content of the message signal is for a call.The number of bits used for this can be freely set depending on the number of services provided by the operator, but the number of bits is constant. is there. When the designated call time information is used as service data, for example, 6 bits for the day designation, 6 bits for the hour designation, and 7 bits for the minute designation, 7 bits are used as the designated time information. The length of these data can be changed depending on the service content.

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

After receiving the radio call signal for the call reservation via the receiving antenna section 61, the receiving section 62 passes the received data to the central control section 63. When the central control unit 63 looks at the service identifier in the data and determines that the call is a timed call, the centralized control unit 63 takes out the call-specified time information (service data) in the data without immediately proceeding to ringing, and the timer unit After setting the time in 65, the data is stored in the memory unit 64. Further, when the designated time comes, the timer unit 65 is activated to notify the central control unit 63 that the designated time has come. In response to this, the central control unit 63 retrieves the stored data from the memory unit 64 again, performs an operation for sounding the speaker unit 66, and displays the message data in the message display unit 67 when there is message data to be displayed. .

[0034]

According to the present invention, once the caller has accumulated the time-designated calling call in the radio-calling device, the radio-calling device can call even if the call is designated with the same time.
Since the information on the designated call time is transmitted to the portable wireless receiver before the designated time, the call can be made without delaying the designated time.

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