DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 shows an example to which the message data communication system of the present invention is applied. In this case, a central control station under the control of a pager service company 3 is provided in a telephone switching network 2 to which a plurality of telephone terminals 1 are connected. 31 and transmitting base station 32
Is connected and, for example, a predetermined call number and message are input from the telephone terminal 1, the pager service company 3
By receiving the call number and the message signal from the transmitting base station 32 via the central control station 31 under the jurisdiction of
A call is made to the paging receiver 4 to which the call number is assigned.

FIG. 2 shows a schematic structure of a paging receiver. In the figure, 11 is an antenna, and this antenna 11 is connected to a receiver 12, and this receiver 12 is connected via a decoder 13. It is connected to the control unit 14. Receiver 1
2 demodulates the FM signal received by the antenna 11.

An ID-ROM 15 is connected to the decoder section 13. The ID-ROM 15 stores an individual ID code individually assigned to the paging receiver, a common ID code for receiving service information, frame data, and the like, and supplies these data to the decoder unit 13. I am trying. The decoder unit 13 has an ID
-The receiving section 12 is driven intermittently based on the frame data taken in from the ROM 15, and the signal demodulated by the receiving section 12 is decoded, and this receives the individual ID code or service information individually assigned to the paging receiver. When it is determined that the common ID code for performing the matching is matched, the matching detection signal and the individual message information and service information received subsequently thereto are sent to the control unit 14.

The control unit 14 has a format discriminating means 14
1 and the expiration date information main body extraction means 142. The format discriminating means 141 discriminates the format of the expiration date information body based on the format information in the service information. The expiration date information body extracting means 142 extracts the expiration date information body in the service information based on the format of the expiration date information body determined by the format determining means 141.

The control unit 14 includes an individual message memory 15, a service information memory 16, and an effective time memory 1
7, the clock unit 18, the matching circuit 19 are connected, the speaker 21 is connected via the speaker driver 20, the LED 23 is connected via the LED driver 22, the display unit 25 is connected via the display buffer 24, and the key input unit 26 is connected. Are connected.

In this case, the individual message memory 15
Is an individual I assigned individually to the paging receiver.
It stores the normal individual message information fetched by the coincidence with the D code.

The service information memory 16 stores service information (service information main body and relative expiration date information added to the service information main body) fetched by matching with the common ID code for receiving the service information. When receiving a call as shown in Fig. 3,
A buffer register BR for temporarily setting the received service information, a mode register M for setting a value designating a mode, a storage message counter n for counting the number of service information stored in a message storage unit MM described later, and a message storage unit A display pointer P that designates the service information by the row address when displaying one row of the service information in the MM on the display unit 25, the speaker 21,
Notification time (8 seconds) and display time (1
It has a timer register T for measuring 3 seconds).

The service information memory 16 has a management data storage unit AM, a message storage unit MM, and a timer storage unit TM. Management data storage section AM here
Manages service information stored in the message storage unit MM, has line addresses A1 to A10, and is set in each line when the service information has expired. The area for the flag Fa, the area for the flag Fm that is set when the service information is protected by the key operation of the owner of the receiving paging receiver, and the service information are stored. It has an address area for storing an address (that is, a row address) in the message storage unit MM. Also, the message storage unit MM
Has row addresses m1 to m10, and each row has a message area for storing service information and a reception time area for storing the reception time of the service information. Then, the timer storage unit TM stores various data of the service information whose expiration date is designated by the elapsed time from the time of transmission, and each line stores in the message storage unit MM of each service information. A memory address area AA for storing a row address of a memory row, a time area TA for storing a specified effective time, and a timer register used as a timer for counting the specified effective time after reception. Have TR.

The valid time memory 17 stores absolute valid term information, and as shown in FIG. 4, an address area A for storing the row address of the storage row of the message storage section MM.
A and an effective time area HA that stores an absolute expiration time (effective time).

The clock section 18 clocks the present time and supplies it to the control section 14 and the coincidence circuit 19. The matching circuit 19 compares the current time measured by the clock unit 18 with the earliest valid time of the valid time information stored in the valid time memory 17, and when the two match, that is, the corresponding service. When the information becomes invalid, a signal indicating that the service information is valid is given to the control unit 14. At this time, the control unit 14 comes to fetch the memory address information corresponding to the matching valid time from the valid time memory 17.

The speaker driver 20 drives the speaker 21 under the control of the control section 14 to generate a ringing tone. The LED driver 22 blinks the LED 23 under the control of the control unit 14 to notify the paging receiver that there is a call. The display buffer 24 is set with various data sent from the control unit 14 to be displayed on the display unit 25.

Next, the expiration date information in the service information received by such a paging receiver will be described. In this case, P is transmitted from the transmission base station 32 of the pager service company 3 and received by the paging receiver.
There are 4 bit code and 7 bit code data formats of service information of OCSAG system. Expiration date information is obtained by using part of the last 1 character (4 bit or 7 bit) respectively. The format indicating the type of the main body is specified, and the expiration date information main body indicating the detailed expiration date information content is specified by using the preceding several characters (variable size).

For example, in the case of a 4-bit code, the last 1
The format specified by the lower 3 bits of the character is "0
00 ”... no expiration date (infinitely valid),“ 001 ”... relative second designation,“ 010 ”... relative minute designation (1),“ 011 ”
... Relative time designation (1), "100" ... Relative date designation, "10"
Eight types of contents are represented, such as 1 "... Relative minute designation (2)," 110 "... Relative time designation (2)," 111 "... Absolute second designation.

The length of each expiration date information body is as shown in FIG. 5, for example. In this case, in the 7-bit code, 4 bits excluding the 3 bits of the format designation are converted into the 3 bits of the format designation in the 4-bit code.
Since one bit except the bit is empty, these are also used as the expiration date information body. In this case, the number of bits that can be used as the expiration date information body is (unit bit number) × (character number) + (empty bit number). This bit number is represented by the number in parentheses in FIG.

Thus, as an example, in the case of a 4-bit code as shown in FIG. 6A, if the format specified by the lower 3 bits of the last character is "100", the expiration date information is displayed. Represents the relative date designation, and 9 bits can be used as the expiration date information body. Here, the writing “0000
If the numeral “30” is represented by “11110”, it means “valid for 30 days after reception” as the detailed deadline information content.

In the case of a 4-bit code as shown in FIG. 6B, if the format specified by the lower 3 bits of the last character is "111", the absolute second is specified as the expiration date information. And 29 bits can be used as the expiration date information body. Here, the detailed expiration date information content in the expiration date information body specified by 29 bits is
For example, if the expiration date is specified by the elapsed time from January 1, 1993, the day, hour, minute, and second are specified by the number of bits shown in the figure.

Next, the operation of the embodiment configured as described above will be described. Now, when the receiving unit 12 receives a received signal via the antenna 11, the control unit 14 executes the receiving process shown in the flowchart of FIG. 7.

In this case, when the receiving unit 12 takes in the received data, it demodulates it and gives it to the decoder unit 13.
The decoder unit 13 judges whether the demodulated received data matches the individual ID code assigned from the individual ID-ROM 15 to the paging receiver or the common ID code for receiving the service information. .

Here, if it matches the individual ID code individually assigned to the paging receiver, the individual message information received subsequently is stored in the individual message memory 15. However, since the operation thereafter is not directly related to the present invention, the description thereof is omitted here.

On the other hand, when the received data matches the common ID code for receiving the service information, the message information subsequently received is fetched as the service information (step 701).

Next, at step 702, the stored message counter n of the service information memory 16 is referred to,
It is determined whether all the message areas of the row addresses m1 to m10 in the message storage unit MM are used (n = 10). If NO here, in step 703,
An empty message area is designated as (n + 1). On the other hand, if YES, in step 704, a flag Fm of the management data storage unit AM is referred to search for an unprotected message area, and the oldest of these is searched. Clear the contents and specify an empty message area.

Then, in step 705, the control unit 1
The format determining means 141 of No. 4 extracts the lower 3 bits of the last one character of the service information and determines the format of the expiration date information. Next, in step 706, the expiration date information body extracting unit 142 of the control unit 14 extracts the expiration date information body based on the format of the expiration date determined by the format determining unit 141. For example, as shown in FIG. 6A, when the designated format is “100” with a 4-bit code, it indicates a relative date designation, and then the 9-bit expiration date information body is “000011110”. In the case of, the relative date “30” is determined as the relative expiration date information.

From this state, in step 707, the received data body which is the service information body is displayed in the message storage unit M.
Write in the empty message area of M. Next, step 7
It is determined whether the expiration date information extracted and determined in 06 is absolute expiration date information, that is, whether absolute seconds are designated (step 70).
8).

Here, as described above, in the case of relative expiration date information, it is determined as NO and the process proceeds to step 709, in which the validity is relative to the time area TA of the timer storage section TM of the service information memory 16. The deadline information (valid time) is stored, and the process ends. In this case, in the memory address area AA corresponding to the time area TA for storing the relative expiration date information, the memory address of the message area of the message storage unit MM in which the received data body was written in step 707 described above is written.

On the other hand, if the expiration date information extracted and determined in step 706 is absolute expiration date information, YES.
Therefore, the process proceeds to step 710, and the valid time memory 1
Absolute expiration date information (effective time) is stored in the effective time area HA of No. 7, and the process is terminated. In this case also, in the memory address area AA corresponding to the valid time area HA that stores the absolute valid term information, the memory address of the message area of the message storage unit MM in which the received data body was written in step 707 described above is written. Be done.

Thereafter, each time the service information is received in the same manner, the received data text is written in the empty message area of the message storage section MM of the service information memory 16, and the last 3 characters of the last one character of the service information are written. When it is determined by the determination of the designated format of the expiration date information using the bits that the relative expiration date information is determined, the content of the expiration date information body is the time area TA of the timer storage unit TM of the service information memory 16. Further, when it is determined that the expiration date information is absolute, the contents of the expiration date information body are sequentially written in the effective time area HA of the effective time memory 17.

After that, the control unit 14 executes the comparison process shown in the flowchart of FIG. In this case, in step 801, the expiration date is monitored by measuring the current time by the clock unit 18. In this case, the matching circuit 19
Current time and effective time memory 17 clocked by the clock unit 18
The effective time of the effective time area HA of the effective time memory 17 corresponding to the service information body stored in is compared. At the same time, the time area T in the service information memory 16 is
The effective time stored in A is compared with the corresponding time measured by the timer register TR. And step 8
Proceeding to 02, the matching circuit 19 or the service information memory 16 judges whether or not the expiration date has passed.

If the expiration date has not passed, the process returns to step 801 and the above operation is continued. on the other hand,
When the expiration date has passed, the process proceeds to step 803, and the expiration date flag Fa in the area for flag Fa corresponding to the expired service information in the management data storage unit AM of the service information memory 16 is set.

In the same manner, when the matching circuit 19 or the service information memory 16 judges whether or not the service information whose expiration date has expired appears by the matching judgment, the expiration flag Fa of the area for the flag Fa corresponding to this appears in sequence. Will be set.

Further, the control unit 14 executes the reading process shown in the flowchart of FIG. First, in step 901, a switch for reading desired service information from the key input unit 26 is turned on. Then, step 902
Then, it is determined whether or not the expiration flag Fa has been set. In this case, the state of the expiration flag Fa of the management data storage unit AM of the service information memory 16 corresponding to the service information desired to be read is checked.

If the expiration flag Fa has not been set, the process proceeds to step 903, and the received data text relating to the corresponding service information is displayed together with the expiration information.

In this case, as shown in FIG. 6A, when the designated format is the relative date designation and the expiration date information body represents the number "300011" of "000011110", As shown in 10 (a), "valid for 30 days" as relative expiration date information is displayed on the display unit 25 together with the received data body and the reception time. Further, as shown in FIG. 6B, when the specified format is “111” and the absolute seconds are specified and the day, the hour, the minute, and the second are specified by a predetermined number of bits, respectively, FIG.
As the absolute expiration date information, for example, "8
17:42:35 on the 13th of the month "will be displayed on the display unit 25 together with the text of the received data. In this case, it is possible to display information indicating whether the message displayed on the display unit 25 is protected.

On the other hand, if the expiration flag Fa has been set, the process proceeds to step 904, and the received data text relating to the corresponding service information is highlighted together with the expiration information. In this case, a predetermined mark may blink instead of the reverse display. The expired service information may be deleted without notifying the user.

Therefore, according to such an embodiment, for the service information, the lower 3 bits of the last one character are used to specify the format for indicating the relative or absolute expiration date information, and at the same time, specify the format. It is configured to specify the expiration date information body that indicates the contents of the expiration date information using the preceding few characters, and when such service information is received, the relative or absolute expiration date information is determined from the specified format. At the same time, based on these judgment results, the respective expiration date information is stored in the service information memory 1
6 or stored in the valid time memory 17, of which the valid time of the valid period information stored in the valid time memory 17 is monitored by the timing of the timekeeping unit 18, and a flag is set for the expired period and these The above state can be displayed on the display unit 25 together with the received data text as required. As a result, when the conventional expiration date information is to be sent together with the service information body, this expiration date information is configured in exactly the same data format as the data forming the service information body. By effectively using the received data, the expiration date information can be added while the length of the service information, which is the received data, is minimized. The user can be notified by the display unit 25 together with the body of the received data, and the service regarding the expiration date management of the service information for the user can be further enhanced.

The present invention is not limited to the above-mentioned embodiments, and can be carried out with appropriate modifications without departing from the scope of the invention. For example, in the above-described embodiment, the reception time data and the expiration date information are displayed together with the reception data body (except for the absolute second designation), but the expiration time that is the expiration date information is added to the reception time data. You may make it display by absolute time.

In the present embodiment, the present invention is implemented only when the service information is received, but it may be implemented when the individual information is received. further,
In the present embodiment, the case where the present invention is applied to the paging receiver has been described, but the point is that the device can receive the message data, and the present invention is also implemented in, for example, PHS, FM multiplex receivers and the like. be able to.
