Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a selective call receiver capable of receiving message information, and more particularly to stopping and starting a selective call function by a predetermined control signal. The present invention relates to a radio selective call receiver capable of performing radio reception control. 2. Description of the Related Art Along with recent developments in electronics technology, miniaturization and high performance of selective call receivers have been remarkable. As a result, a function that can receive message data as well as a call-only function has been commercialized and provided for information services. [0003] With the spread of these information services, there have been cases where service fees have been delinquent, and countermeasures have become a problem. [0004] As measures of this kind, for example,

No. 136) and other proposed technologies, and the contents thereof are “a ROM having a selective call number provided with a timer”, “a ROM having a built-in battery”, and “a battery operated by a secondary battery”. A decoder control circuit controls the receiving operation of the decoder. " [0005] Among the above-mentioned prior arts, the first two items have a configuration in which the ROM cannot be used for a certain period of time. In the case of receiving the service, there is a problem that it is inconvenient to go to a service company, and the old ROM is discarded, thereby wasting resources. Also, the third technique has a problem in that since the secondary battery is used, the secondary battery must be replaced when the secondary battery is exhausted. [0006] Since these three techniques control the calling number or the calling number coincidence detecting circuit, the function bits (PO) added to the calling number are controlled.
However, there is a problem that it is not possible to perform control such that only a specific information service is stopped in services that provide different information services. A radio selective call receiver according to the present invention is a radio selective call receiver which has a call number and receives message information, and controls contents of message processing corresponding to the call number. And storage means for storing, if the call number is detected, means for identifying whether or not the call number is prohibited reception based on the control content ,
Means for canceling the processing of the message when the call number is identified as being prohibited from being received. In the radio selective call receiver of the present invention, there is provided a radio selective call receiver having a call number and receiving message information, storage means for storing control contents of message processing corresponding to the call number, Means for writing the control content of the reception control signal corresponding to the call number into the storage means in response to the reception control signal added to the call number, and receiving the control content based on the control content stored in the storage means.

PROM), 12 is a display (LCD), 13 is a voltage booster circuit, and 14 is a power switch. The control content of the reception control signal is set to EEP
The means for writing to the ROM 11 responds to the reception control signal added to the first call number assigned to the device, and controls at least the information service based on the second call number provided to the information service for the unspecified majority. It constitutes control means. FIG. 2 is an explanatory diagram showing an example of a signal configuration used in the embodiment shown in FIG. 1. (a) shows the signal configuration, (b) shows the transmission signal configuration, and SC shows Sync signal,
ID1 to ID4 are call signals, M1 to M3 are message signals, and RecC is a reception control signal. ( C ) shows one pattern of the synchronization signal, and (d) shows the word structure of the calling signal and the message signal. ( E ) shows the bit configuration of the paging signal, where the first bit (MSB) is 0 and the address of the paging signal is assigned to 2 to 19 bits.
Function bits (third call signal) added to the address are assigned to the 0 and 21 bits. In the information service, the information content is changed by the difference of the function bits. (F) shows the bit configuration of the reception control signal used in the present embodiment. The reception control signal has 8 bits of 12 to 20 bits for 1stID (first call number assigned to the device) and 2ndID (second call number). And four types of function bits (A
(Call to D call) to control eight addresses in total. The symbol * in (d) indicates an identification bit, which is 0 for a call signal and 1 for a message signal. According to the signal configuration shown in (f), at least two types of the information service can be received by the third call number added to the second call number provided for the information service for the unspecified majority. This is applied to a selective call receiver. Next, the operation at the time of receiving a call signal in the embodiment shown in FIG. 1 will be described with reference to the time chart of FIG. 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 PROM 5 in advance. When they match, the decoder 4 sends the address signal (d) and the function bit signal (d) together with the address reception signal (b).
(F) is input to the CPU 10 via the interface 9. Then, the decoder 4 receives the address reception signal (b)
After that, the message signal data (h) and the clock signal (f) following the calling signal are output to the CPU 10.
The CPU 10 reads the message signal data (h) at the rising edge of the clock signal (f). Next, after reading the address signal ID (N + 1) (a) following the message signal, the CPU 10 outputs a message signal data end signal (h) 'to the decoder 4. In response to the message signal data end signal (h) ', the decoder 4 stops outputting the message signal data (h) and the clock signal (f). When the CPU 10 outputs the message signal data end signal (h) ', the CPU 10 internally processes the message signal data. When the processing of this data is completed, an alert control signal (i) 'and alert sign signals (j)' and (k) 'are output to the decoder 4, and the display 12 is driven to display a message signal.
Then, the decoder 4 outputs the alert sign signal (j) ',
The sound signal according to (k) 'is output to the amplifier 6, which amplifies the sound signal and drives the speaker 8. Next, the operation at the time of receiving the reception control signal in the embodiment shown in FIG. 1 will be described with reference to the flowchart of FIG. First, the CPU 10 detects the call signal shown in FIG. 2B, and if its address is its own address set in the PROM 5 (process 402), the 32-bit data following the call signal is detected. Read (process 40)
3). The read (NO in process 404) when the MSB bit of the data is 1, for example, that it has received the message signal M ₁ Following call signal ID ₁ in FIG. 2 (b), the example in EEPROM11 FIG 2 (f ) 1s
It reads its own reception control data set for tID and determines whether or not this is reception inhibition (process 40).
8). If the function bit shown in FIG. 2F that has already been received is compared with the reception control data, if it is determined that the reception is prohibited, the apparatus returns to the standby state. If the reception is not prohibited, the subsequent 32-bit data is read (process 409). When another address signal (MSB bit is 0) is read (process 410), the message signal data end signal (h) is read. ) ', And then outputs an alert control signal (i)' for sound notification and an LCD control signal for display (step 411). Next, when the MSB bit is 0 in step 404, it is determined whether or not 32-bit data following the address signal is a reception control signal (step 405).
Then, when not receiving the control signal, call signal ID ₄ Following its calling signal ID ₃ in the data string shown in FIG. 2 (b)
Is received, and since it is another address signal,
It outputs the message signal data end signal (h) ', reads its own reception control data set for the 1st ID in the EEPROM 11, and compares this reception control data with its own function bit already received. To determine whether reception is prohibited. When the reception is prohibited, the mobile phone returns to the standby state.
ONLY is displayed (processing 412 to 413). Then, when it is determined in step 405 that the reception control signal is the reception control signal, it means that the reception control signal RecC is received following the calling signal ID ₂ in the data sequence of FIG. 2B, and in this case, the reception control is performed. The control content contained in the signal is stored in the EEPROM1
Write to 1. At the same time, a message signal data end signal (h) 'is output, and the display 1 indicates the stop of the service or the return of the stopped service together with the address.
2 (process 407). For example, the first address is an individually selected call number assigned to an individual, the second address is a common number for an unspecified majority, and the function bits associated with the common number are used to convert the A call into stock price information. Service, B call to gold market information service, C
The call is an information service for rice prices and the D call is an information service for horse race results. When a certain subscriber stops the service due to the delay of the service fee for the information service of the race result of the horse race, the first address calling signal and the D call service stop of the second address are notified by the reception control signal. Send The subscriber's selective call receiver receives this,
“2nd ID Dcall OUT” is displayed on the display 12.
"SERVICE" is displayed to notify the customer of the suspension of the service. When the service is restored, the display 12 is displayed.
Above, "2nd ID Dcall IN SERVIC
E "is displayed. As described above, according to the present invention,
By writing the control contents to the EEPROM by the reception control signal, it is possible to wirelessly control reception of a specific information service or restart reception of a specific information service without using a secondary battery for a specific subscriber. The above effect is extremely large.
