Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio paging receiver generally called a pager or pager and a selective radio paging system using a radio base station that calls the radio paging receiver.

[0002]

2. Description of the Related Art There has conventionally been a selective paging system for calling a person carrying a paging receiver (hereinafter referred to as a called party).

A "pager system" described in Japanese Patent Application Laid-Open No. 7-336444 (hereinafter referred to as Reference 1)
It consists of a telephone, pager and exchange. This exchange comprises a transmitting device, a storage device, and a confirmation receiving device.

In the "paging system" described in Reference 1, when a page is called, the call number is stored in a storage device. The called party of the pager device accesses the exchange at the appropriate time and dials his calling number to the receiving device. The confirmation accepting device compares the call number dialed by this operation with the call number stored in the storage device, and if there is a matching call number, sends out a voice announcement indicating that there is a call. If there is no matching call number, a voice announcement indicating that there is no call is transmitted.

According to the technique described in Reference 1, even if a call is made to a location with poor reception sensitivity such as in a tunnel, subway, or underground yard, or to a pager located outside the reception area, the called party is not notified of the call. There is a problem that there is no.

At this time, from the point of view of the person who called the pager (caller), the calling procedure was performed by the telephone, and the message was transmitted to the called party despite the fact that the message was stored in the exchange. There is a problem that there is no.

A "message posting notification system" described in Japanese Patent Application Laid-Open No. 1-125049 (hereinafter referred to as Reference 2) comprises a telephone, a telephone network, a pager calling center, and a pager with a display. The apparatus includes a network control unit, a voice storage unit, a subscriber telephone number storage unit, and a PB signal transmission unit.

In the technique described in Reference 2, a user A who makes a call connects a telephone to a voice storage device via a telephone exchange network, and stores a call number and a message in a storage device.

The voice storage device connects to the pager calling center, automatically dials the calling number of user B with reference to the subscriber's telephone number stored in the storage device, and calls the user B. Notify that. By this notification, the user B can know that a message has been posted in his / her mailbox.

According to the cited example 2, even if the user B, that is, the called party is out of the service area or is traveling in a tunnel, subway, underground yard, or the like where the radio wave condition is poor, the pager is notified of the call. And the called party does not notice the call.

From the viewpoint of user A, that is, the caller,
Even though the message to the called party is stored in the mailbox of the voice storage device from the telephone, there is a problem that the called party cannot be contacted.

JP-A-2-44821 (hereinafter referred to as Reference 3)
The "selected radio paging method" described in the following section) is a transmission composed of a call reception unit, an information conversion unit, a number-of-calls setting unit, an encoding unit, a number-of-calls decrement unit, a transmission unit, and a sound / display unit. Unit, a receiving unit, a synchronization detecting unit, a decoding unit, an address combining unit, an address storing unit, a ringing frequency detecting unit,
It is configured by a receiving unit configured by a display unit.

[0013] When calling the receiver, the transmitting side sends the same information a plurality of times by sending a frame including address information and a plurality of pieces of transmission information following the address information in a single call.

On the other hand, the receiving side compares the address already stored in the storage unit with the information on the frame number received by the receiver and the information continuously transmitted and the information on the number of calls, and checks the number of calls. The sounding operation and the display operation of the transmission information according to the value are performed.

According to the technique described in Reference 3, in order to transmit the same information a plurality of times (m times) using a plurality of (n times) frames in one call, n which has been conventionally transmitted once is used.
Xm times the amount of information must be transmitted. For this reason,
The transmitting base station needs to control an enormous amount of information, which is difficult to control and requires a long time for transmission processing.

[0016]

The problems of the above-described conventional paging system can be summarized as follows.

In the conventional radio paging system, when the called party is moving in an area where the radio wave condition is poor, the called party cannot be called by only one transmission made by the calling party.

In the conventional radio paging system, a caller transmits alphanumeric characters, katakana, and special characters specified by keys and key combinations input from a telephone.
In order to transmit the transmission information in a document form, a large number of characters (textual messages) are used to transmit the data, so that the line occupation time becomes long. As the number of messages increases, the transmission base station transmits data that increases. There is a problem that it takes time.

Further, in the conventional radio paging system, there is a problem that the message and the number of characters are limited because only a message of a few dozen characters can be accepted by a key input by the caller from the telephone.

The problem to be solved by the present invention is to provide a radio paging system in which these problems of the conventional radio paging system are improved. That is, it is an object of the present invention to provide a radio paging system capable of notifying a called party that a call has been made even when the location of the called party at the time of calling is a place where the radio wave condition is poor.

Another problem to be solved by the present invention is to increase the amount of information that can be transmitted by a caller and reduce the line occupation time required for a base station to call a radio pager once. To provide a wireless paging system compatible with both.

[0022]

FIG. 1 shows a system configuration of the present invention, and FIG.

According to the present invention, since the call is transmitted only when the caller makes a call for calling in the conventional selective radio calling system notification system, the user accidentally moves in a tunnel, subway, or underground yard with poor reception sensitivity. Since the called party of the terminal cannot receive the call, the first feature is that the call is transmitted several times at intervals in the ocean of the flowchart 1 of the present proposal.

According to the present invention, in the conventional system notification system for selective radio call, when a caller transmits a message when moving in a place having poor reception sensitivity or is located outside the area, the message cannot be received. Since the caller cannot contact the caller, the conventional system has to send a call command for the selective radio call many times. Since it is difficult for the wireless base station to control a large number of transmission commands at one time, or it takes time to process the transmission commands, the number of data to be transferred is reduced as compared with the related art, and transmission is performed at one time. The first feature can be realized by shortening the time.

In order to solve the above problems, the present invention provides a radio paging receiver in which a caller calls and transmits a message to a radio paging receiver possessed by a called party via a radio base station. The radio base station stores the message data of the caller and assigns a document number corresponding to the message data, and a calling step in which the radio base station transmits the document number to the radio call receiving device. Receiving the document number from the radio call receiving apparatus, connecting to the radio base station via a general public line, certifying the called party by the radio base station; The message number is transmitted to the wireless base station, and the wireless base station searches for the message data corresponding to the document number. Provides a paging method for a radio paging receiver which comprises a step of transmitting to the user.

4. Time control unit 1 for controlling transmission timing
05, a data modulation unit 106, and an antenna 107.

(2) Configuration of Radio Call Receiver FIG. 2 is a functional block diagram of the radio call receiver 200 of the present invention. The radio paging receiver 200 includes an antenna 201, a demodulation unit 202, a control unit 203 that controls the operation of the radio paging receiver 200, a comparison unit 204 that compares already received data with currently received data, a storage unit 205, and a buzzer. A notification unit 206 that notifies the called party of an incoming call by sounding a speaker or the like, vibrating the housing, displaying on a screen, or the like.

(3) Paging of Radio Paging Receiver 200 The operation of the radio base station 100 and the radio paging receiver 200 will be described with reference to FIGS. FIG. 3 shows the wireless base station 100.
FIG. 4 is a flowchart showing the operation of the paging receiver 200.

When a caller wants to contact a called party from a calling terminal 121 such as a general subscriber telephone, a public telephone, or a portable telephone, the calling party is called a radio page receiver 200 of the called party.
Is called (301). This telephone is connected to the incoming call control unit 101 of the wireless base station 100 via a general public line 110.

The incoming call control unit 101 determines whether the incoming call is for calling the corresponding radio page receiver 200 by the calling party or for confirming the message by the called party (302). , 303).

When the incoming call is made by the caller, the incoming call control unit 101 sends a pre-stored voice message to the caller, and inputs the message to the called party by using the numeric keypad or voice of the telephone. (30
4).

The incoming call control unit 101 gives a document number for management to the input message, and is transferred to the storage device 103 via the message search control unit 102 together with the message. The storage device 103 stores the transferred document number and message number (305).
The stored message and document number are used later when the called party confirms the message.

The document number is stored in the transmission control unit 1.
04. The transmission control unit 104 prepares the document number as transfer data and transfers the data to the data modulation unit 106.
Sends a call of the called party's radio call receiver 200 (306, 307).

If the number of calls has not reached the predetermined number, the transmitted document number is transmitted again after a predetermined time (308, 309). The timing of this transmission is performed by the time control unit 105. By repeatedly transmitting the same document number in this manner, the probability that the called party receives the call can be improved.

On the other hand, the document number (data) of the message transmitted by the radio wave emitted from the antenna of the base station
Are received through the antenna 201 of the radio pager 200 in FIG. 2 and demodulated by the demodulation unit 202 (401).

The control unit 203 compares the demodulated data with the call number of the radio call receiving apparatus 200 to determine whether it matches or not (402). If they do not match, the call is to another paging receiver and is ignored.

If the call numbers match, a match / mismatch with the already stored document number is made (403).
If they match, they are already received data, so they are ignored, and the process ends. If they do not match, they are newly received data, which is stored in the storage unit 205 (404) and the notification unit 20.
4 notifies the called party of the incoming call (405).

The called party who has confirmed the incoming call makes a telephone call to the base station, connects to the incoming call control section 101, and specifies confirmation of the message (303).

The incoming call control unit 102 prompts the called party to input a document number using voice or the like. The called party is the notification unit 20
The document number and the like stored in the storage unit 205 are referred to on the screen of No. 6 and input to the message search control unit 102 (310).

The message retrieval control section 102 retrieves the input document number (311). If there is a matching document number, the message retrieval control section 102 reads out the message data stored in the storage device 103 and receives the received document number via the incoming call control section 101. The caller is notified (312). If there is no matching document number, it is similarly notified that no message exists (313).

The read data is automatically deleted after a certain period of time (not shown).

[0049]

According to the radio paging system of the present invention, since the transmission is repeatedly performed several times to the radio paging receiver, the probability that the radio paging receiver can receive the call can be improved.

For example, if the called party is located at a place where a call can be received with a probability of 70% per transmission, the radio paging system of the present invention has a repetition rate of 3 and is 9 times.
The called party can be notified of the call with a probability of 7.3%, and the probability of notifying the called party of the call can be greatly improved.

In the conventional method, message information of up to 960 characters can be transmitted. However, since the occupation time of one line is long, the memory capacity of the base station is reduced, and the channel cannot be used effectively, the message transmission is not possible. The number was minimized. For example, when the transmission rate is increased from 300 bit / s to 900 bit / s in order to increase the amount of information to be transmitted, and transmission is performed, in order to maintain the electric field level, the transmission rate is 3 dB larger than when the transmission rate is 300 bit / s. A transmitting device that can output power is required. On the other hand, according to the present invention, the amount of information that the base station must transmit to the paging receiver for one message is minimized to shorten the occupation time of the line. A station can process a large number of messages in the same time.

The terminal, like the conventional paging system,
The caller transfers the modulated message by calling the telephone or the like, but has the function of canceling the same message because the same data is transferred several times as in the present invention. A satisfactory system can be provided.

In the conventional radio paging system, a text message of a key input by a caller through a telephone is modulated and transmitted each time. In the present invention, since the storage device of the base station temporarily stores data, data other than the conventional text message can be handled. For example, FAX
Also, data and mail transferred by personal computer communication or the like can be handled as messages, and correspondingly, the output method can be used by facsimile, personal computer communication, telephone, etc., and the use range is extremely widened.

Although the present invention has been described based on the embodiments, the present invention is not limited to these embodiments, and it is understood that changes and improvements can be made within the ordinary knowledge of those skilled in the art. Of course.
