DETAILED DESCRIPTION OF THE INVENTION

[0001]

The present invention relates to a technical field of controlling a receiver operation from a base station in a selective paging method in which a receiver is selectively called from a base station.

[0002]

2. Description of the Related Art Paging receivers (hereinafter referred to as "pagers") and selective call receivers such as cellular telephones are becoming widespread, but it is required that a base station establish a system for controlling the operation of a pager, for example. . Advanced radio paging system handling pager Standard RCR STD-43
Japanese Association of Radio Industries and Businesses describes a system that can handle various information messages, such as security messages, standard numeric messages, alphanumeric messages, and hexadecimal / binary messages.

FIG. 7 shows a signal protocol described in the above standard, where S1 is a synchronization unit 1, FI is frame information,
Reference numeral 2 denotes a synchronization unit, and BI denotes block information. And AF
Is an address field in which the word of the address individually assigned to each pager is located, which may include an address assigned to each group of pagers. VF is a vector field, and MF is a message field. The identifier (type) of the message is assigned to the VF, and the content of the message is assigned to the MF. IB is an idle block.

[0004] Various information messages can be carried in the MF, and the security message in the MF indicates some kind of control performed by a paging system operator through a pager. The side can control the operation of the pager. For example, overseas, when a user moves from the area under the jurisdiction of one business to the area under the jurisdiction of another business, the user changes the pager setting based on the maintenance data from the base station by contacting the business. Such things are being done.

On the other hand, a so-called sub-service, which provides a common message such as traffic information and horse racing information to each pager on a regular or irregular basis from the base station side, is considered. This common message is assigned and assigned to a certain group, for example, a group of pagers who have contracted with a business operator in advance, and is captured and displayed when the pagers of the group recognize the common address.

The problem here is that the common information is provided to the pager of the user who has canceled the contract with the business operator or has delinquent the fee. In this case, since the transmission of the individual address of the pager from the base station is prohibited, the pager cannot receive the individual message.
Since the common address has been transmitted, it can be received.

As means for avoiding such a situation, it is conceivable to use the security data. That is, the base station sends a security message to the pager whose contract has been released to the pager's individual address and transmits a security message stating "discard the data even if a common address is received", You will not be able to receive common message services.

[0008]

As described above, as a method of controlling the operation of the pager at the base station side, the use of security data has already been performed for some control, and the acceptance of a common address is not permitted. In performing such control, use of maintenance data is being studied.
However, in this case, (1) In an area where the base station and the pager cannot handle the security data because both the base station and the pager cannot handle the security data,
For example, a delinquent user may receive a common message such as traffic information by receiving a common address. At present, it is difficult to establish a service that provides a common message because each office cannot keep pace with the handling of maintenance data. (2) In the advanced radio paging system, the base station cannot confirm that the pager has received the security data, and the pager does not always perform the intended operation. For example, if the user turns off the power, or enters a basement or tunnel and is temporarily unable to receive radio waves from the base station, and the base station issues maintenance data, Control, for example, the acceptance of the common message cannot be disallowed, and the base station cannot confirm it.
Thereafter, the pager can receive the service of the common message.

An object of the present invention is to solve such a problem and to provide a technique capable of reliably controlling the operation of a selective call receiver from the base station side.

[0010]

According to the present invention, there is provided a base station comprising:
By transmitting the individual address individually assigned to each receiver, the receiver corresponding to the individual address is selectively called, and the receiver for which the fee is not paid is called out.
In selected radio paging way to stop the transmission of the individual address of the receiver, the receiver when not receiving a certain period of time an individual address, is transmitted from the base station, the number
Reception of information to which an address other than another address is assigned is not permitted . The present invention also provides
Not only is the entire radio calling method covered, but also the receiver itself.

FIG. 1 is an example of the principle diagram of the present invention. If, for example, an individual address “A2” is assigned to the receiver 2, the receiver 2
The address of the received signal transmitted from the base station 1 is compared with its own individual address, and if they match, a sound or a predetermined message is displayed. On the other hand, the accumulation elapsed time monitoring unit 2
In 02, the period in which the individual address is not received (accumulation period) is counted, and when the accumulation period exceeds a predetermined period, the operation state changing unit 203 changes the operation state of the receiver.

Here, the determination that the individual address is not received for a certain period is made, for example, by using a count value which is increased by the elapse of time of a clock unit provided in the receiver and initialized when the individual address is received, This may be when the count value exceeds a predetermined value. In this case, the count value may be increased by elapse of the time of the clock unit or by turning on the power.

The individual address transmitted from the base station is
Reception of information assigned address is attached to the non-less order to not permitted, for example, the acceptance of the common information may be disallowed.

[0014]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The following is an example of a system in which a base station transmits a common message, which is common information, in addition to an individual message, for example, at regular intervals, and prohibits users such as nonpayment from receiving the common message. Therefore, an embodiment of the present invention will be described. First, an individual message is a message sent in association with an individual address assigned to each pager (however, the message itself may be sent or an identification code may be sent), and the common message is a group of a certain pager For example, a message assigned to all pagers who have a special contract with a business establishment. Actually, one pager can hold a plurality of addresses, for example, eight addresses. However, for the sake of convenience, it is assumed that both the individual message and the common message are one.

FIG. 2 schematically shows the base station 1,
A call number and a message code corresponding to a message to be displayed are input to the receiving unit 12 from a terminal 10 such as a telephone or a personal computer via the general public switched telephone network PSTN 11. The processing section 13 attaches an address corresponding to each call number, and transmits the code or information corresponding to the code from the transmission section 14. The call number is usually unique to the pager. However, when common information is transmitted from a predetermined location to a group of pagers via a PSTN 11 by a personal computer, for example, the call number is a common number.

FIG. 3 is a diagram showing a receiver (pager) 2. The pager 2 temporarily stores a signal transmitted from the base station 1 in a buffer memory 22 via a receiving unit 21 and a synchronizing unit (not shown). The address collation unit 23 performs address collation while maintaining frame synchronization. Assuming that the individual message assigned to the pager 2 is A and the common message is B, these A and B are stored in the address storage unit 24.
Is stored in advance.

The address collating section 23 is composed of an address storing section 24
Is compared with the received address, and if the received address is one of A and B, the processing unit 3 which also serves as the operation state changing unit is notified of the fact, and the processing unit 3 fetches the data. . The processing unit 3 performs a process according to the information content of the captured data. Reference numeral 31 denotes a message memory in which a message corresponding to the message code is stored in advance. When the information content is a message code, the processing unit 3 displays a message 32 corresponding to the code from the message memory 31 on the display unit, and, for example, causes the sound unit 33 to generate a predetermined sound. When the information content is the message itself, the message is displayed on the display unit 32, for example.

Further, the pager 2 includes a storage elapsed days monitoring unit 4 which is a characteristic part of this embodiment. In this embodiment, the period during which the individual address is not received is referred to as the accumulated elapsed days. The monitoring unit 4 monitors the accumulated elapsed days, and the accumulated elapsed days exceeds a predetermined number of days, for example, 30 days. This is a part for instructing the processing unit 3 to prohibit (non-permit) capturing of a message corresponding to the common message B. Hereinafter, for the sake of simplicity, the message corresponding to the individual message A will be referred to as an A message, and the message corresponding to the common message B will be referred to as a B message.
Elapsed days counting section 41 that counts the accumulated days elapsed,
A clock section 42 and an elapsed days determination section 43 are provided.

As long as the processing unit 3 does not notify the reception of the A address, the elapsed day counting unit 41 keeps updating every time the date in the clock unit 42 changes, that is, every time after midnight.
Alternatively, every time the power is turned on, the EP
It has a function of adding the elapsed days (accumulated elapsed days) of a non-volatile memory such as a ROM one day at a time, and resetting the accumulated elapsed days to zero when a notification of the reception of the A message is received from the processing unit 3. The elapsed days determination unit 43 includes:
Judge whether the number of elapsed days exceeds the specified number of days,
It has a function of sending a B address permission instruction to the processing unit 3 if it has not exceeded, and a B address non-permission instruction if it has exceeded. The monitoring unit 4 is shown as a block for convenience in the figure, but the functional part is made of software in this embodiment.

Next, the operation of this embodiment will be described with reference to the flowchart of FIG . For example, if the power is turned on for the first time after purchasing the pager, the pager is initially set to disallow reception of the B address, that is, disallow display of the message.
The flow proceeds to NO, and it is determined in step S2 whether the date of the clock unit 42 has been changed. In the initial setting, the display of the B address may be permitted.

Since this date is initially the same as the date when the power is turned on, the process proceeds to step S3, where it is determined whether a message has been received. If no message has been received, it is determined in step S4 whether or not the power has been turned off. Since the power has been turned on, the process returns to step S2 .
If no message is received on that day, step S
Around the flow of 2 → S3 → S4, the same flow is repeated even if the date changes and the next day comes.

If the address B is received, the process proceeds from step S3 to step S5. Here, it is determined whether the address of the message is A or B. Since the address is the B address, the process proceeds to step S6. At this stage, since the display of the B address is still not permitted, the flow proceeds to NO and returns to the above cycle. If it is assumed that the address A has been received, the process proceeds from step S3 to step S7 via step S5, and the processing unit 3 permits the display of the message of the address B (B).
Address display permission state). Further, in step S8, the elapsed days counting section 41 receives the notification of the reception of the A address from the processing section 3, so that the count value n of the accumulated days has elapsed.
Is reset to 0. Next, in step S9, the processing unit 3
Reads out the message corresponding to the A address from 31 and causes the display unit 32 to display the message together with the sound of the sounding unit 33.

Thereafter, since the B address display is permitted, when the B address is received, steps S3 → S5 →
The process proceeds from S6 to S9, and the message of the B address is displayed. This message is a common message issued from the base station 1, for example, traffic information, and the processing unit 3 displays the information content following the address of the signal protocol on the display unit 32. When the date on the clock 42 changes to the next date,
The process returns from step S2 to step S1, but since the B address display is now permitted, the process proceeds to step S10, in which the count value of the number of days of storage is increased by one and n is rewritten to n + 1. Subsequently, the process proceeds to step S11, where the elapsed days determination unit 43 sets the elapsed days n to a predetermined number of days, for example, 30 days.
It is determined whether or not the date has passed, and if not, the process returns to step S2. If it has exceeded, the process proceeds to step 12 and the processing unit 3 issues an instruction to disallow the B address from the elapsed days determination unit 43.
, Whereby the processing unit 3 enters a state in which the B address display is not permitted.

As can be seen from the above description, in the normal case, the receiver 2 receives the address A many times during, for example, 30 days. You can receive messages. On the other hand, if the transmission of the A address in the base station is prohibited due to, for example, delinquent charges, the pager will not automatically accept the B address after 30 days, and will not be able to receive the secondary service. When the power is turned off, the count value of the elapsed days counting section 41 stops, but when the power is turned on, the process proceeds from step S1 to S10, and the count value of the elapsed days increases by one. State.

As described above, since the display of the common message is prohibited when the individual address is not received for a certain period of time, the active state of the pager can be consequently obtained without performing active control such as transmission of security data from the base station 1. Can be controlled. Therefore, unlike the case of using the security data, there is no problem of how to confirm the reception of the security data, and since the pager can be controlled regardless of whether or not the security data is handled, it is possible to continue to receive only the sub service illegally. This is very effective in establishing a system that provides sub services such as sending a common message.

[0026] Then the pager will be described with reference to FIGS. 4 and 5 for the case that includes the date and time automatic correction function. In FIG. 5, reference numeral 51 denotes an automatic date and time correction unit, and a clock unit 4 based on date and time information transmitted periodically from the base station 1.
2. It has a function to accurately set the date and time. The accumulated elapsed days monitoring unit 4 includes an auxiliary clock unit 52. The auxiliary clock unit 52 is the same as the clock unit 42 in ticking the date. However, when the power is turned off, the count operation stops. The date stops. This date is stored in a non-volatile memory such as an EPROM, and when the power is turned on, the auxiliary clock unit 52 starts to operate from the date when it stopped.

In this case, as shown in FIG. 4, steps S13 to S16 are added to the flow shown in FIG. That is, it is determined in step 13 whether or not the date and time automatic correction function is in the operating state. If the function is not in the operating state, the number of elapsed days n is stored in the same manner as the flow described above.
Is increased by one, but if it is in the operating state, it is determined in step S14 whether the current date of the clock unit 42 matches the date (accumulation date) of the auxiliary clock unit 52. For example, if the power is not turned off, the two dates match, but if the power is turned off for three days, for example, the accumulation date of the auxiliary clock unit 52 is the date three days before and the current date is that day. Will not match.

Then, the process proceeds to a step S15, wherein the number of elapsed days of accumulation n is added by, for example, three days by the difference between the two dates.
After correcting the accumulated number of days n in this way, the accumulated date is adjusted to the current date in step 16 and it is determined in step 11 whether the accumulated number of days exceeds the predetermined number of days as in the previous embodiment. When the battery of the pager is removed, the current date also stops. However, when the battery is inserted, the date is automatically corrected to the correct date by the automatic date and time correction function.

According to such an embodiment, even if the counting of the number of elapsed days is stopped by turning off the power, the blank period in which the counting was stopped when the power is turned on is compensated for. Therefore, the system becomes more effective.

In the above, the present invention has been made in view of how to control a receiver such as a pager, that is, how to change the operation state of the pager from the base station side. As an example of the change of the above, the prohibition of the common message was mentioned as an example, but the present invention is not limited to this, and the common message may be permitted by not receiving the individual address for a certain period, for example, one pager holds a plurality of individual addresses If so, some of them may be rejected or accepted.

When a plurality of common addresses are set in a certain pager group, one or more common addresses may be prohibited from being accepted,
Although a common address is accepted for the time being, a vector following the address may be determined in a signal protocol, and in the case of a predetermined vector, processing may be prohibited for a temporary vector whose read timing is changed, for example.

The present invention is not limited to prohibiting the acceptance of addresses and vectors, but may be configured to prohibit the operation of the sounding unit so that no sound is produced, or the sound may be changed. Alternatively, a special message may be displayed. Further, the function of the pager itself may be stopped. However, the "fixed period" in which the individual address is not received for a fixed period includes a period until the count value reaches a certain value as described above.

In the present invention, when the security data is handled, the security data may be used together with the security data. For example, the reception of the common address, the individual address or the vector is prohibited by the security data, and the individual address is stored for a certain period. The reception may be similarly prohibited when not receiving. In this case, even if the period during which the individual address is not received does not become a fixed period, the operation state of the receiver changes when the security data is received. The selective call receiver is not limited to a pager, but may be a cellular telephone or the like.

[0034]

As described above, according to the present invention, payment of non-payment is performed regardless of whether maintenance data is handled .
The receiver is not allowed to receive specific information from the base station.
Permission can be granted .
