Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a data receiving apparatus for receiving numbered data.

[0002]

2. Description of the Related Art As a conventional communication system for transmitting and receiving character information using a telephone line, there are a wireless paging system, a home banking system, and the like. As a transmission data format in the wireless paging system, there is a POCSAG system.

[0003] However, with the development of mobile communication technology in recent years, service usage fees have been reduced and personal use, especially business use as well as young people, in particular, have spread, and as a result, the number of service subscribers has increased. , It is difficult to provide sufficient services.

As described above, with the recent rapid increase in demand and expansion of functions, it is necessary to enhance services.
As a result, an advanced paging scheme defined by the standard “RCR STD-43” has been introduced.

First, the advanced paging method will be briefly described. FIG. 19 shows a transmission data structure adopted in this advanced paging scheme. In FIG. 19, 70 is a data configuration transmitted in one hour, 71 is a cycle configuration,
Reference numeral 72 denotes a frame configuration of one frame. The data structure 70 consists of 15 cycles numbered from "0" to "14", which indicate the cycles transmitted in one hour. The cycle configuration 71 is “0”
, And 128 frames numbered from “127”, which indicates the number of frames transmitted in 4 minutes. One frame is 1.875 seconds, and data of 42 frames is transmitted in one minute. The frame configuration 72 includes 1
The data for the frame is divided into eight according to the data content.

[0006] The frame structure 72 includes a synchronizing unit 1 (S
1) 72A, frame information (FI) 72B, synchronization section 2
(S2) 72C, block information section (BI) 72D, address field (AF) 72E, vector field (VF) 72F, message field (MF) 72
G and an idle block (IB) 72H.

The synchronizing unit 1 (S1) 72A is composed of 112 bits of 1600 bps modulated by binary FSK.
Which of modulation scheme and transmission rate of data transmitted after block information (BI) is selected from binary FSK scheme / 1600 bps binary FSK scheme / 3200 bps 4-level FSK scheme / 3200 bps 4-level FSK scheme / 6400 bps Is stipulated information.

The frame information (FI) 72B is a binary FS
It is composed of a K-modulated 1600 bps 32-bit word, and stores the frame number of the present frame, the present cycle number, information indicating a plurality of transmission indications and the number of transmissions. Synchronizing section 2 (S2) 72C
(S1) This is timing information for determining the reception timing with the modulation method and transmission rate specified by 72A.

The fields 72D to 72G and the idle block (IB) 72H are stored in the synchronization section 1 (S1) 7
This is information transmitted with the modulation scheme and reception speed specified in 2A, and is composed of 11 pieces of data of one block transmitted in 160 ms units. Block information section (BI) 72
D is a block for storing information such as a word number and the number of words which are the starting points of an address field (AF) 72E and a vector field (VF) 72F described later. The address field (AF) 72E is a paging destination identification number. Is a field for storing an address. The vector field (VF) 72F is paired with the above-mentioned address field and a message field (MF) to be described later.
A field for storing information such as a word number and a word number serving as a starting point of 72G, and a message field (M
F) 72G is a field for storing message data according to the data format defined by the vector field (VF) 72F. Then, the idle block (I
B) 72H is an unused block, in which "1"
Alternatively, a pattern of “0” is set.

Further, in the block configuration 73, three blocks of a synchronization section 1 (S1) 72A, frame information (F1) 72B, and a synchronization section 2 (S2) 72C are set in the synchronization signal section 73A, and an interleave block section ( # 0
# 10) A block information section (B) in which word data of a plurality of (up to four) phases are interleaved is stored in 73B.
Each block of I) 72D, address field (AF) 72E, vector field (VF) 72F, message field (MF) 72G, and idle block (IB) 72H is set.

A user using a pager corresponding to the advanced paging system can select a basic service and these additional services and make a contract for each address. For example, if the user subscribes to the information service,
Various information messages can be received from various information providers.

In this advanced paging system, one of the services provided by using the above data structure includes a "message serial number service" and a "message retransmission service" in addition to the basic paging service. .

[0013] This means that, for each address of a paging receiver (hereinafter referred to as a pager), a message field (MF) is sent from the center-side equipment to a pager to be called.
Within the 72G, the message data is transmitted with the individual message number added thereto, so that the subscriber can recognize the transmission order of the message data, and the center side stores and manages the message data transmitted in the past with this message number for each address. If the pager receives message data with a skipped message number, the center notifies the center of the message number corresponding to the unreceived message data by notifying that there is unreceived message data. Thus, a request for retransmission of message data is made.

[0014] When the retransmission-requested message data is received, the notification of the non-reception is canceled.

More specifically, in the case of the "message serial number service" and the "message retransmission service", the center side transmits a message field (MF) 7 corresponding to the "message serial number service" shown in FIG.
The message is transmitted in a word structure of one block of 2G.

In this figure, K represents a message checksum. N is a message number data portion, which stores 5-bit cyclic data from 0 to 63.

R is a message search flag,
In the data of the message field corresponding to the “message serial number service”, this R is always set to 1. S is bit data that specifies whether to display this message in a special format.

In response to this data, the center transmits message data to which a message number consecutive from 0 to 63 is added in accordance with the contracted pager address. Is stored and managed in the existing database in association with the message number.

The form of the message to be subjected to the message serial number service is a vector field (VF).
72F, a hexadecimal / binary message corresponding to a numbered numeric message, a kanji / kana mixed message, and an alphanumeric message are supported.

[0020]

However, the "message serial number service" and the "message retransmission service" have the following problems.

1. On the pager side, the notification that there is unreceived message data is notified by notifying the center of the message number corresponding to the unreceived message data.
Since the message is canceled only by the arrival of the unreceived message data, even if the unreceived message data is useless, the notification cannot be reset unless a retransmission request is made.

2. The center side individually manages the message data to which the message number is added by using this message number. However, since the 64th message data is overwritten and managed as the message with the message number 0, a long-term contract is required. If the subscriber is outside the receiving area, all the numbered message data sent during this time will be subject to retransmission, but if the subscriber returns to the receiving area,
If the message number skips one or more rounds, only some unreceived message data will be retransmitted.

When the subscriber returns to the receiving area and the numbered message data arrives just once, the number skip error that occurred before this message is not reported.

Accordingly, the present invention has been made in view of the above problems, and has been described in a data receiving apparatus such as a pager which receives and stores and manages message data with a message number and notifies the message number skipping. Provided is a data receiving device which enables a message number to be deleted for a message, not only notifies an error of a skipped message number, but also prompts a deletion operation of the number, thereby improving a use environment in receiving numbered message data. It is.

Next, an incoming call processing operation according to the first embodiment will be described.

FIGS. 6 and 7 are flow charts for explaining the incoming call processing of the pager 1. FIG.

First, when the CPU 7 detects that the power is turned on by the sliding operation of the main switch 31, the CPU 7 supplies power to the respective circuit units connected to the CPU 7, initializes the respective circuit units, and performs a reception standby mode. to go into.

At this time, the operation is started according to the initialization setting, the control data of the reception data buffer circuit 6 corresponding to each frame pattern is set, and the reception standby in the frequency band and phase set by the ID-ROM 12 is performed. Enter the state. In this reception standby state, the CPU 7 intermittently waits for 1.875 seconds (1 frame) to a maximum of 10 seconds every 30 seconds until frame synchronization is detected by the reception of the synchronization section 1 (S1) 72A of the synchronization signal section 73A. Receive for 2 minutes. After that, the synchronization unit 1 (S
1) Frame synchronization is detected by receiving 72A.

When the frame synchronization is detected, the receiving unit 5 intermittently drives in the time slot of its own frame according to the control of the reception data buffer circuit 6 based on the data of the received synchronization signal unit 73A, and detects the reception signal. , Demodulated, and output to the reception data buffer circuit 6.

The reception data buffer circuit 6 sequentially stores the bit data of one frame input from the reception unit 5 into 8b.
It is rearranged into parallel data of it and output to the bus B.
Thereafter, the CPU 7 sequentially captures the 8-bit parallel data of one frame and stores the parallel data in the buffer memory 11, and also stores the parallel data in the buffer memory 11 based on the previously received frame pattern data of the synchronization unit (S1) 72A. , And deinterleave 9 to sequentially recover the data, perform error correction processing in the BCH decoder 11, and write the data again into the buffer memory 11.

Thereafter, the ID-ROM 1 shown in FIG.
2 is compared with the address data in the address field (AF) 72E stored in the buffer memory 11 when any one of the address data #A, #B, #C, and #D registered in , A match signal is output, and the reception operation of the reception unit 5 is continued so that the reception data buffer circuit 6 receives all the data of this frame (step S1).

Subsequently, incoming address data that matches in the address field (AF) 72E of the fetched one-frame data is #A, #B, #C, #D (#A) registered in the ID-ROM 12 shown in FIG. (Step S2), and it is determined whether or not the received address data is the address #D of the numbered message (step S3).

If the incoming address data is not #D but #A
In the case of (one address data dedicated to individual call), #B (two address data dedicated to individual call), or #C (address data dedicated to group call), the message data is a normal message data arrival. Is stored in the normal message data memory area 14 a shown in FIG. 4 in the RAM 14, an incoming call is notified by a notification sound of the speaker 17 driven by the driver 16, and a message based on the incoming message data is displayed on the display unit 2. Display control is performed so as to be displayed (step S17), and this processing ends.

If the incoming address data is #D (address data dedicated to numbered message data), the time and date of the incoming call and the incoming time are measured by the timer 7a (step S4). The incoming call waiting time from the numbered message data received last time is calculated from the incoming time (step S5), and the incoming date and time, the incoming time, and the incoming standby time together with the incoming numbered message data are stored in the numbered message data memory area 14b. Is stored in each column in association with the storage address (step S6).

Thereafter, the reception waiting time from the reception of the previous numbered message data to the reception of the current numbered message data and the previous numbered message data stored in the numbered message data memory area 14b are corresponded. Then, the respective incoming call waiting times are compared (step S7).

According to this comparison, in step S8, the incoming call waiting time from the last reception of the numbered message data to the current reception of the numbered message data is as follows.
It is longer than any incoming waiting time corresponding to the previous numbered message data, that is, the incoming waiting time from the last incoming numbered message data to the current numbered message data is the longest waiting time. Then, the message number of the numbered message data received this time is compared with the message number of the numbered message data received last time to determine whether the message number is skipped (step S9). If the message number of the message data of the current incoming call is higher than that of the previous incoming call, the incoming call is notified by the notification sound of the speaker 17 driven by the driver 16, and a message based on the incoming message data is displayed on the display unit 2. Display the number.

However, since the message number is skipped and the longest waiting time, several unnumbered numbered message data exist before the numbered message data that has arrived this time, and the message number remains unreceived. May have gone around once.

Therefore, in such a case, the message number is displayed in reverse video and blinks together with the display of the message, and there is a possibility that a large number of messages may not be received. Display a prompting message (step S1
0).

FIG. 8 shows an example of the storage of the numbered message data memory area 14b by the receiving process of the numbered message data in step S10. In the storage example of FIG. 8, in the numbered message data sequentially received, the incoming waiting time from the previous time to the incoming of the current numbered message data is “4330 minutes”, which is the longest compared to the past incoming waiting time. Shows the data storage state when the message number is further stored.

FIG. 9 shows a display example of the display unit 2 by the receiving process of the numbered message data in step S10. In the display example shown in FIG. 9, the message is “going ahead” and the message number is [0
6] is displayed in reverse blinking. And
To indicate that there are several unnumbered numbered message data and that the message number may have gone round while still not receiving a message, the message "Most of the messages may not be received! Reset? "?" Is displayed.

In this case, when a reset operation due to the pressing of the main switch 31 is detected (step S1)
1) The message number stored together with the previous numbered message data stored in the numbered message data memory area 14b is deleted, and the message data with the deleted message number is transferred to the normal message data memory area 14a. (Step S12),
The incoming call processing ends. When any one of the memory key 32, the select key 33, and the set key 34 is operated, only the notification is reset.

The incoming standby time from the last incoming numbered message data to the current numbered message data is the longest standby time. Further, in step S9, the message number of the current incoming message data and the last When the message number of the incoming message is not skipped, the incoming call is notified by the notification sound of the speaker 17 driven by the driver 16, and the message and the message number based on the incoming message data are displayed on the display unit 2.

However, even if the message numbers are consecutive, the longest standby time is set. Therefore, even if the message numbers are apparently continuous, there is a possibility that the message number may go around one cycle without receiving a call. .

Therefore, in such a case, the message number is displayed in reverse video with the display of the message, and there is a possibility that the message has not been received for one cycle or more. It is displayed (step S13).

FIG. 10 shows an example of the storage of the numbered message data memory area 14b by the incoming processing of the numbered message data in step S13. In the storage example of FIG. 10, in the numbered message data sequentially received, the incoming waiting time from the previous time to the incoming of the current numbered message data is “4330 minutes”,
It shows the data storage state in the longest case as compared with the past call waiting time.

FIG. 11 shows a display example of the display unit 2 by the incoming call processing of numbered message data in step S13. The display example shown in FIG. 11 shows a case where the message is “going ahead” and the message number [05] is highlighted. And
In order to indicate that the message number may have gone round without receiving a call, a message indicating that the message number may have been deleted for one or more cycles! Do you want to reset? Is displayed. You.

In this case, when a reset operation due to the pressing of the main switch 31 is detected (step S1)
1) The message number stored together with the previous numbered message data stored in the numbered message data memory area 14b is deleted, and the message data with the deleted message number is transferred to the normal message data memory area 14a. (Step S12),
The incoming call processing ends. When any one of the memory key 32, the select key 33, and the set key 34 is operated, only the notification is reset.

Further, at step S8, any of the incoming waiting times corresponding to the previous numbered message data is longer than the incoming waiting time from the last incoming numbered message data to the current numbered message data. Long, that is, if it is determined that the incoming standby time from the reception of the previous numbered message data to the reception of the current numbered message data is not the longest standby time, then the message number of the currently received numbered message data and Then, it is compared with the message number of the numbered message data received last time to determine whether the message number is skipped (step S14). If the message number of the message data of the current incoming call is higher than that of the previous incoming call, the incoming call is notified by the notification sound of the speaker 17 driven by the driver 16, and a message based on the incoming message data is displayed on the display unit 2. Display the number.

However, since the message number is skipped, there is numbered message data that has not been received.

Therefore, in such a case, the message number is displayed blinking together with the display of the message, and there is a numbered message which has not been received yet, and a message urging the deletion of the message number of the message data received up to the previous time is displayed (step S15).

FIG. 12 shows an example of the storage of the numbered message data memory area 14b by the incoming processing of the numbered message data in step S15. In the storage example of FIG. 12, among the numbered message data sequentially received, the message number of the previously received message data is [04], and the message number of the current numbered message data is [06], which is skipped. Indicates the data storage state when the data is stored.

FIG. 13 shows a display example of the display unit 2 by the incoming call processing of the numbered message data in step S15. The display example shown in FIG. 13 shows a case in which the message is “going ahead” and the message number [06] is blinking. And
In order to indicate that there is a possibility that there is a message that has not been received, a message indicating that there is a possibility that the message has not been received! Reset the message number is displayed.

In this case, when a reset operation due to the pressing of the main switch 31 is detected (step S1)
1) The message number stored together with the previous numbered message data stored in the numbered message data memory area 14b is deleted, and the message data with the deleted message number is transferred to the normal message data memory area 14a. (Step S12),
The incoming call processing ends. When any one of the memory key 32, the select key 33, and the set key 34 is operated, only the notification is reset.

Further, in step S8, the waiting time from the reception of the previous numbered message data to the reception of the current numbered message data is not the longest waiting time. And the message number of the numbered message data received last time, the notification of the incoming call is made by the notification sound of the speaker 17 driven by the driver 16 and the display of the incoming message data on the display unit 2. Is displayed based on the message (step S1).
6), terminate the incoming call processing.

FIG. 14 shows an example of the storage of the numbered message data memory area 14b by the incoming processing of the numbered message data in step S16. In the storage example of FIG. 14, in the numbered message data sequentially received, the message number of the previously received message data is [04] and the message number of the current numbered message data is continuous with [05]. 3 shows a data storage state of the data.

FIG. 15 shows a display example of the display unit 2 by the incoming call processing of numbered message data in step S16. The display example shown in FIG. 13 shows a case where the message is "going ahead" and the message number is [05].

As described above, in the pager 1 of the first embodiment, corresponding to the message serial number service for receiving the numbered message data, the numbered message data includes the message number, the arrival date and time, and the arrival time. ,
In addition, the RAM 14 has a numbered message data memory area 14b for storing the incoming call waiting time from the last incoming call to the present incoming call, and in the incoming processing of the numbered message data, an address for the numbered message data is provided. Upon detecting the arrival of data, the RAM 14
Is stored in the numbered message data memory area 14b, and the waiting time between the last incoming call and the current incoming call is calculated, and the message number of the currently received message data and the message number of the last incoming message data are skipped. If yes, the incoming call waiting time stored in the past is compared with the incoming call waiting time from the previous incoming call to the present incoming call.

If the CPU 7 determines that the standby time between the last incoming call and the current incoming call is the longest standby time, the CPU 7 instructs the deletion of the message number of the incoming call message data up to the previous time, and executes a reset operation. When confirmed, the message numbers of all the message data received up to the previous time are deleted, and the normal message data memory area 14 in the RAM 14 is used as normal incoming message data.
a, when receiving and storing data to which a number is added, by deleting the number of the numbered message data stored in the past, the number jump to the meaningless unreceived message is performed. Error notification can be eliminated.

Also, in a pager or the like that receives and stores data to which a number is added and manages it, it is possible to eliminate the notification of a number skip error for an erroneous unreceived message due to being outside the receiving area for a long time.

In the first embodiment, the incoming call waiting time interval is stored for each incoming numbered message data. However, only the longest incoming call waiting interval for numbered message data received in the past is stored. A memory area may be provided in the RAM 14 to compare the current incoming call waiting interval with the stored maximum incoming call waiting interval when the numbered message data arrives.

(Second Embodiment) In the first embodiment, non-reception of one or more cycles of message data is determined based only on the length of the incoming call waiting time. By using the average value of the incoming call waiting time, it is possible to determine whether or not one cycle or more has not been received.

Hereinafter, a second embodiment of the present invention will be described in detail with reference to the drawings. It is to be noted that the same drawings as those of the first embodiment are used, and the description of the same numbers is omitted.

FIGS. 16 to 18 show a second embodiment of a pager to which the data receiving apparatus of the present invention is applied.

In the second embodiment, the CPU (Cent
The ral processing unit 7 analyzes the received message data based on various control programs stored in the ROM 13 and controls each circuit unit in the pager 1 according to a control signal input from the key input unit 3. I do. In addition, a built-in clock circuit 7a for counting an incoming waiting time until an incoming call is received. In the incoming call processing of numbered message data in the incoming message data described later, the incoming time, the previous numbered message data and the current number are displayed. A numbered message data memory area in the RAM 14 in which the numbered message data in the received message data is associated with the incoming time and the incoming call waiting time by counting an incoming waiting time indicating an incoming interval with the numbered message data. 14b. Then, the incoming call waiting time between the previous incoming call and the present incoming call is compared with the average value of the past incoming waiting time stored in the average value memory area in the RAM 14, and the incoming call between the previous incoming call and the present incoming call is compared. If the standby time exceeds the average value, or if the message number of the previously received message data and the message number of the currently received message data are skipped, instruct the deletion of the previously received message number, When the pressing of the main switch 31 is detected, the message numbers of the messages with all the message numbers which have arrived immediately before are erased, stored as normal incoming message data in the normal message data memory area 14a in the RAM 14, and the reception standby state is set. Return.

RAM (Random Access Memory) 14
Is a normal message data memory area 14a for storing a normal incoming message, a numbered message data memory area 14b for storing a numbered incoming message as shown in FIG. An average value memory area 14c for storing an average value of the standby time.

Next, an incoming call processing operation according to the second embodiment will be described.

FIGS. 17 and 18 are flow charts for explaining the incoming call processing of the pager 1. FIG.

First, when the CPU 7 detects that the power is turned on by sliding the main switch 31, the CPU 7 supplies power to the respective circuit units coupled to the CPU 7, initializes the respective circuit units, and performs a reception standby mode. to go into.

At this time, the operation is started according to the initialization setting, the control data of the reception data buffer circuit 6 corresponding to each frame pattern is set, and the reception standby in the frequency band and phase set by the ID-ROM 12 is performed. Enter the state. In this reception standby state, the CPU 7 intermittently waits for 1.875 seconds (1 frame) to a maximum of 10 seconds every 30 seconds until frame synchronization is detected by the reception of the synchronization section 1 (S1) 72A of the synchronization signal section 73A. Receive for 2 minutes. After that, the synchronization unit 1 (S
1) Frame synchronization is detected by receiving 72A.

When the frame synchronization is detected, the receiving section 5 intermittently drives in the time slot of its own frame according to the control of the received data buffer circuit 6 based on the data of the received synchronizing signal section 73A, and detects the received signal. , Demodulated, and output to the reception data buffer circuit 6.

The reception data buffer circuit 6 successively converts the bit data of one frame input from the reception unit 5 into 8b
It is rearranged into parallel data of it and output to the bus B.
Thereafter, the CPU 7 sequentially captures the 8-bit parallel data of one frame and stores the parallel data in the buffer memory 11, and also stores the parallel data in the buffer memory 11 based on the previously received frame pattern data of the synchronization unit (S1) 72A. , And deinterleave 9 to sequentially recover the data, perform error correction processing in the BCH decoder 11, and write the data again into the buffer memory 11.

Thereafter, the ID-ROM 1 shown in FIG.
2 is compared with the address data in the address field (AF) 72E stored in the buffer memory 11 when any one of the address data #A, #B, #C, and #D registered in , A match signal is output, and the reception operation of the reception unit 5 is continued so that the reception data buffer circuit 6 receives all the data of this frame (step S21).

Subsequently, the incoming address data that matches in the address field (AF) 72E of the fetched one-frame data is #A, #B, #C, #D (#D) registered in the ID-ROM 12 shown in FIG. (Step S22), and it is determined whether the received address data is the address #D of the numbered message (step S23).

If the incoming address data is not #D but #A,
In the case of (one address data dedicated to individual call), #B (two address data dedicated to individual call), or #C (address data dedicated to group call), the message data is a normal message data arrival. Is stored in the normal message data memory area 14 a shown in FIG. 16 in the RAM 14, an incoming call is notified by a notification sound of the speaker 17 driven by the driver 16, and a message based on the incoming message data is displayed on the display unit 2. Display control is performed so as to be displayed (step S38), and this processing ends.

If the incoming address data is #D (address data dedicated to numbered message data), the timer 7a measures the incoming date and time and the incoming time (step S24). The incoming call waiting time from the previously received numbered message data is calculated from the incoming time (step S25), and the incoming date and time, the incoming time,
The incoming call waiting time is stored in each field in the numbered message data memory area 14b in association with the storage address (step S26).

[0108] Thereafter, the waiting time from the arrival of the previous numbered message data to the arrival of the current numbered message data, and the number of the previously numbered message data received in the past stored in the average memory area 14c. A comparison is made with the average value of the incoming call waiting time (step S27).

As a result of this comparison, in step S28, if the incoming call waiting time from the last incoming of the numbered message data to the current incoming of the numbered message data exceeds the average value of the incoming waiting time of the numbered message data. If it is determined, the message number of the numbered message data that has arrived this time is compared with the message number of the numbered message data that has arrived last time to determine whether the message number is skipped (step S29). If the message number of the message data of the current incoming call is higher than that of the previous incoming call, the incoming call is notified by the notification sound of the speaker 17 driven by the driver 16, and a message based on the incoming message data is displayed on the display unit 2. Display the number.

However, since the message number is skipped and exceeds the average value of the waiting time for incoming calls,
Before the numbered message data that arrived this time, there may be several unnumbered numbered message data, and there is a possibility that the message number has made one round without being received.

Therefore, in such a case, the message number is displayed in reverse video and blinking together with the display of the message, and there is a possibility that a large number of messages may not have been received yet. Display a prompting message (step S3
0).

An example of the storage of the numbered message data memory area 14b in the receiving process of the numbered message data in step S30 is the same as that of FIG.

FIG. 9 shows a display example of the display unit 2 by the receiving process of the numbered message data in step S30.

In this case, when a reset operation due to the pressing of the main switch 31 is detected (step S3).
1) The message number stored together with the previous numbered message data stored in the numbered message data memory area 14b is deleted, and the message data with the deleted message number is transferred to the normal message data memory area 14a. Then, the incoming call waiting time from the last incoming call to the present incoming call is set as the average value of the incoming call waiting time in the average value memory area 14c (step S32), and the incoming call processing is terminated.

On the contrary, the main switch 3
No reset operation due to pressing of 1 is detected and memory key 3
2. When any one of the select key 33 and the set key 34 is operated, only the notification is reset and the message number is not erased. The value is calculated and reset to the average value memory area 14c (step S33),
The incoming call processing ends.

The incoming call waiting time from the previous incoming of the numbered message data to the current incoming of the numbered message data exceeds the average value of the incoming waiting time,
Further, in step S29, when the message number of the current incoming message data and the message number of the previous incoming message are not skipped, the incoming call is notified by the notification sound of the speaker 17 driven by the driver 16 and the display unit 2 is notified. A message and a message number based on the incoming message data are displayed.

However, even if the message numbers are consecutive, the message number exceeds the average value of the waiting time for the incoming call. There will be.

Therefore, in such a case, the message number is displayed in reverse video with the display of the message, and there is a possibility that the message has not been received for one cycle or more. It is displayed (step S34).

As a result of the incoming processing of the numbered message data in step S34, an example of storage in the numbered message data memory area 14b is as shown in FIG.

A display example of the display unit 2 by the incoming process of the numbered message data in step S34 is the same as that shown in FIG.

In this case, when a reset operation due to the pressing of the main switch 31 is detected (step S3).
1) The message number stored together with the previous numbered message data stored in the numbered message data memory area 14b is deleted, and the message data with the deleted message number is transferred to the normal message data memory area 14a. Then, the incoming call waiting time from the last incoming call to the present incoming call is set as the average value of the incoming call waiting time in the average value memory area 14c (step S32), and the incoming call processing is terminated.

On the contrary, the main switch 3
No reset operation due to pressing of 1 is detected and memory key 3
2. When one of the select key 33 and the set key 34 is operated, only the notification is reset without erasing the message number, and the incoming call waiting time between the last incoming call and the current incoming call is taken into account. The average value is calculated and reset in the average value memory area 14c (step S3).
3) Terminate the incoming call processing.

Further, if it is determined in step S28 that the incoming waiting time from the last incoming of the numbered message data to the current incoming of the numbered message data does not exceed the average value of the incoming standby time, then
The message number of the numbered message data received this time is compared with the message number of the numbered message data received last time to determine whether the message number is skipped (step S35).

When the message number of the message data of the current incoming call is higher than that of the previous incoming call, the incoming call is notified by the notification sound of the speaker 17 driven by the driver 16 and the display unit 2 displays the incoming message data. Displays the message and message number based on.

However, since the message number is skipped, there is numbered message data that has not been received.

Therefore, in such a case, the message number is displayed blinking together with the display of the message, and there is an unreceived numbered message, and a message urging the deletion of the message number of the previously received message data is displayed (step S36).

FIG. 12 shows an example of the storage of the numbered message data memory area 14b by the incoming processing of the numbered message data in step S36.

Further, a display example of the display unit 2 by the incoming processing of the numbered message data in step S36 is the same as that shown in FIG.

In this case, when a reset operation due to the pressing of the main switch 31 is detected (step S3).
1) The message number stored together with the previous numbered message data stored in the numbered message data memory area 14b is deleted, and the message data with the deleted message number is transferred to the normal message data memory area 14a. Then, the incoming call waiting time from the last incoming call to the present incoming call is set as the average value of the incoming call waiting time in the average value memory area 14c (step S32), and the incoming call processing is terminated.

In contrast, the main switch 3
No reset operation due to pressing of 1 is detected and memory key 3
2. When one of the select key 33 and the set key 34 is operated, only the notification is reset without erasing the message number, and the incoming call waiting time between the last incoming call and the current incoming call is taken into account. The average value is calculated and reset in the average value memory area 14c (step S3).
3) Terminate the incoming call processing.

In step S28, the incoming standby time from the last incoming of the numbered message data to the current incoming of the numbered message data does not exceed the average value of the incoming standby time. When the message number of the data and the message number of the numbered message data received last time are continuous, the incoming call is notified by the notification sound of the speaker 17 driven by the driver 16 and the incoming message is displayed on the display unit 2. A message and a message number based on the data are displayed (step S
37) Then, taking into account the incoming standby time of the previous incoming call and the current incoming call, an average value of the incoming standby time is calculated,
The average value memory area 14c is reset (step S3
3) Terminate the incoming call processing.

FIG. 14 shows an example of the storage of the numbered message data memory area 14b by the incoming processing of the numbered message data in step S37.

A display example of the display unit 2 by the incoming call processing of the numbered message data in step S37 is the same as that shown in FIG.

As described above, in the pager 1 according to the second embodiment, in correspondence with the message serial number service for receiving numbered message data, the numbered message data includes the message number, the arrival date and time, and the arrival time. ,
The RAM 14 has a numbered message data memory area 14b for storing the waiting time from the last incoming call to the present incoming call, and stores the average value of the past incoming waiting time. In the data reception processing, when the reception of the address data for the numbered message data is detected, the data is stored in the numbered message data memory area 14b in the RAM 14, and the reception standby time between the previous reception and the current reception is calculated. Then, the average value of the incoming call waiting time is compared with the incoming call waiting time between the previous incoming call and the present incoming call.

Then, the CPU 7 determines whether the incoming call waiting time between the previous incoming call and the current incoming call exceeds the longest standby time, or the message number of the previous incoming message data and the message number of the current incoming message data. If the message is skipped, it is instructed to delete the message number of the previous incoming message data, and after confirming the reset operation, the message numbers of all the message data received until the last time are deleted, and Since it is stored in the normal message data memory area 14a in the RAM 14, it is unnecessary to delete the number of the numbered message data stored in the past when receiving and managing the data to which the number is added. Number skip for unreceived numbered message data It is possible to eliminate the notification of the error.

In addition, it is possible to eliminate the notification of an erroneous number skip error due to unreceived numbered message data due to being outside the receiving area for a long time.

In each of the above-described embodiments, the message numbers of all the messages received up to the previous time are erased and stored as normal incoming message data in the normal message data memory area 14a in the RAM 14. If you request to resend a message in
Since all numbered messages can be stored in the pager 1, all numbered message data can be stored by having the paging center resend all numbered message data. is there.

In the incoming call processing of each of the above-described embodiments, a message prompting an operation for erasing the storage of the message number is displayed. Although the message number stored in the memory area 14b is deleted, the process of resetting the message number is unnecessary and the message number may be automatically deleted.

Thus, the discontinuous storage state of the message numbers can be canceled without any user's awareness, and the state can be returned to the reception standby state. When the discontinuous storage state of the message numbers occurs, the user's operation can be performed. The burden can be omitted.

Further, in the second embodiment,
The method of calculating the average value of the call waiting time is generally a method of summing up the past call waiting times and dividing the total by subtracting 1 from the number of stored message data.
The present invention is not limited to this, and the average value of the waiting time of the previous incoming call and the current incoming waiting time of the current incoming call is added to the average value of the incoming waiting time stored in the average value memory area 14c. The time may be reset as an average value.

The average value of the incoming call waiting time may be sequentially calculated from several recent incoming message data and updated.
