Abstract

PURPOSE:To control the reception inhibition or reception restart of specific information service to a specific subscriber by radio without using a secondary battery by using a reception control signal to write the control content in an EEPROM. CONSTITUTION:An output signal from a waveform shaping circuit 3 is compared with its own call number written in advance in a PROM 5 by a decoder 4. When the both are coincident, a reception control signal is inputted to a CPU 10 together with an address reception signal. After an address signal in succession with a message signal is read in the CPU 10, and a message signal and a data end signal are outputted to the decoder 4. When the CPU 10 outputs the message signal data end signal, the message signal data is processed in the inside and the reception of various information service is inhibited or the receiver in the inhibiting state is released for the reception again based on the content of the information service for lots of unspecified persons written in advance in the EEPROM 11.

Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a selective calling receiver capable of receiving message information, and particularly to a selective calling receiver capable of stopping or starting a selective calling function by a predetermined control signal. The present invention relates to a radio selective calling receiver that can control reception by radio.

[Conventional technology]

With the recent progress in electronics technology, selective call receivers have also become more compact and highly functional. As a result, devices that have a call-only function and can also receive message data have been commercialized and are being provided for information services.

By the way, with the spread of these information services, cases of non-payment of service fees have been seen, and countermeasures have become an issue.

As a countermeasure of this kind, for example,
42638 (Japanese Unexamined Patent Publication No. 186135/1983) and patent application No. 186135
No. 9-42639 (Japanese Unexamined Patent Publication No. 60-186136) and other proposed technologies, the contents of which are
``Books with a timer in the ROM that writes the selective call number'', ``Books with a ROM with a built-in battery'', and ``
A decoder control circuit that is operated by a secondary battery controls the reception operation of the decoder.

[Problem that the invention seeks to solve]

Among the above-mentioned conventional technologies, the first two terms are those in which the ROM becomes unusable after a certain period of time, so if you want to continue receiving information services again, it is inconvenient to go to a service company. However, there was a problem in that the old ROM had to be discarded, leading to a waste of resources. Also, 3
Regarding the second technique, there is also a problem that since a secondary battery is used, when the secondary battery is exhausted, the secondary battery must be replaced.

Since all three of these technologies control the calling number or the calling number matching detection circuit, the function pin (according to the POC8AG code) added to the ejection number is used in services that perform different information services. However, there was a problem in that the control was such that only certain information services were stopped.

[Failure to solve the problem]

The wireless selective calling receiver according to the present invention has a first calling number assigned to a device and a second calling number provided for information service to an unspecified number of people, and has a second calling number added to the first calling number. The first control means controls at least the information service based on the second call number in response to the reception control signal.

Further, a wireless selective calling receiver according to another invention of the present invention includes:
In a selective calling receiver capable of receiving at least two or more types of information services according to the third calling number added to the second calling number provided for the information service to the unspecified number of people, the receiving control signal The system is equipped with a second control means for controlling a specific information service.

[Effect]

In the present invention, in response to the detection of a control signal following a selective calling number assigned to each receiver, it is possible to freely receive various information services using a common number targeted at an unspecified number of people and function bits associated therewith. A receiver that is currently prohibited or in a prohibited state is enabled to receive data again.

Then, the control contents of the received control signal are stored in the EEPROM11.
The means for writing in the device is configured to control the information service based on the second call signal provided to at least an unspecified number of people in response to the reception control signal added to the first call number assigned to the device. constitutes a means.

FIG. 2 is an explanatory diagram showing an example of the signal configuration used in the embodiment shown in FIG. 1, where (a) shows the signal configuration, (b) shows the sending signal configuration, and SC Synchronization signal, IDI

Then, a total of eight addresses of four types of function bits (A call to D call) are controlled for each ID.

Note that the * mark in (d) indicates an identification bit, and O...
- When it is a calling signal, 1... When it is a message signal.

The signal configuration shown in (e) above is such that at least two calls are made to the information service by a third call number added to a second call number provided for the information service to an unspecified number of people.
This applies to selective calling receivers that can receive more than one type of call.

Next, the operation at the time of receiving a calling signal in the embodiment shown in FIG. 1 will be explained with reference to the time chart of FIG. 3.

First, the signal (a) output from the waveform shaping circuit 3 is compared by the decoder 4 with its own calling number written in the FROM 5 in advance. When the two match, the decoder 4 outputs the seat address reception signal (b), address signal (e), and function bit signal (d).

(•) is input to the CPU 10 via the interface 9. Then, the decoder 4 receives the address reception signal (b)
After outputting the message signal data (f) following the calling signal, it outputs the clock signal (f) to the CPolG. This CPU IO reads the message signal (data output) at the rising edge of the clock signal (f).

Next, the CPU 10 reads the address signal ID(N+1)(a) following the message signal, and then
A message signal data end signal (hl) is output to the decoder 4. The message signal data end signal (h) causes the decoder 4 to stop outputting the message signal data and the clock signal (f).

Then, the CPU 10 sends a message signal data end signal (
h), the message signal data is processed internally. When the processing of this data is completed, the decoder 4 drives the Hairard Puntrol signal (1) and the ARA 12,
Display message information. Then, the decoder 4 outputs a sound signal based on the alert sign signal (j), Qc) to the amplifier 6, which amplifies the sound signal and drives the speaker 8.

Next, the operation at the time of reception control signal reception in the embodiment shown in FIG. 1 will be explained with reference to the flowchart in FIG. 4.

First, when the CPU 10 detects the address reception signal (b), it reads 32 bits of data following this address signal (process 403). Then, when the MSB bit is 1, read the reception control data of EEFROMII (
Processing 404), - When reception of the address signal is prohibited, the device returns to the standby state (Processing 408).

If reception of the address signal is not prohibited, the next 32 bits of data are read, and when another address signal (MSB bit is O) is received, a message signal data end signal (h) is output, and the sound notification is continued. An alert control signal (1) for display and an LCD control signal for display are output (process 411).

Next, if the MSB bit is 0 in process 404, it is determined whether the 32-bit data following the address signal is a reception control signal (process 4o5).

If it is not a reception control signal, it is another address signal, so a message signal data end signal (h) is output, and if the address signal is reception prohibited, the standby mode returns to the standby state, and if it is not prohibited, K is output with a sound notification. TO on display 12
NE 0NLY is displayed (processes 412 to 413). When it is determined in processing 405 that the reception control signal is a reception control signal, the control contents included in the reception control signal are stored in EEFROM11.
write to. At the same time, a message signal data end signal (h) is output, and the stoppage of the service or the restoration of the stopped service is displayed on the display 12 along with the address (process 40T).

For example, the Imt address is an individual selective calling number assigned to an individual, the 2nd address is a common number that targets an unspecified number of people, and the function bit attached to the common number allows calls to be sent to a stock price information service, B Call is a gold price information service, and C call is a US price information service.

D-Call is an information service for horse racing results.

If a certain subscriber is in arrears in paying the service fee for a horse race result information service and the service is to be stopped, a reception control signal for stopping the D-call service of the 2nd address is sent on the 1st address call. .

The subscriber's selective call receiver receives this and displays K-2nd ID Dcau OUT 8ERVIC on the display 12.
E' is displayed to notify customers of the suspension of service. In addition, when the service is restored, 11C' on the display 12
Display 2ndID DcatA IN 5ERVICI'.

〔Effect of the invention〕

As explained above, according to the present invention, by writing the control contents into the EEFROM using a reception control signal, a secondary battery can be used to wirelessly prohibit or restart reception of a particular information service for a particular subscriber. Since it can be controlled without using it, the practical effect is extremely large.
