DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a message receiver for receiving, storing, and storing a message addressed to a user by radio, and more particularly, to automatically classifying a received message according to a title and storing and storing the received message. The present invention relates to a message receiver in which a message having an unnecessary title is not stored and stored.

[0002]

2. Description of the Related Art In recent years, a radio selective calling communication system using a message receiver such as a pager can transmit not only numeric information but also character information such as hiragana and kanji, and simply sends a message to an individual. In addition, various information such as news, stock prices, weather, etc. provided by an information provider can be transmitted. In such a radio selective call communication system, the provided weather information and the like are wirelessly transmitted to a common call number (group call number), and a plurality of message receivers having the group call number receive the information. Information display service is provided.

In order to provide such an information providing service, for example, Japanese Patent Publication No. 5-35933 discloses that one of two codes is used for an individual selective calling service and the other is used for an information providing service. The invention used for this is disclosed. However, in the present invention, even if the message receiver receives various service information from the information providing company, the service information (information message) is stored in the same memory area as a normal individual message addressed to the individual. Even when it is desired to display and output only a specific information message among the stored information messages, an individual message addressed to an individual and an information message are displayed in a mixed manner. The user must repeatedly perform the display switching operation, which is extremely inconvenient.

In order to solve such a problem, for example, Japanese Patent Application Laid-Open No. HEI 8-19027 discloses that a user reads an arbitrary message stored in a message memory by operating a key and sets a format and a file name. Arbitrary settings can be registered in the format message memory, which allows the user to freely classify and store received messages, thereby facilitating file management and format data in which received messages are registered. There is disclosed a message data receiver which can be automatically classified and stored based on the message data.

[0005] However, in this message data receiver, the received message is automatically classified unless the message stored in the message memory is read out and the format and file name are registered in advance in the format message memory. However, there is a problem that the user still has to perform a complicated operation for classification. Even if the received message is an information message relating to the service information, if the format and the file name are not registered, the message is stored in the memory area for storing the normal individual message addressed to the individual, so that the individual message is stored. When the memory capacity required for performing the operation is reduced and many information messages are stored and held, there is also a problem that even when an individual message is received, it cannot be stored and displayed.

[0006]

Here, the information messages relating to the service information as described above are transmitted in a wider variety and more frequent than individual messages, but in consideration of the actual use situation, Users do not always need all types of information messages sent,
The type of information message required varies depending on the individual user or the time and case. However,
In the conventional message receiver, all the information messages are received and stored in the memory as long as the group call numbers addressed to them are the same. However, there is a problem that the memory capacity for storing the necessary messages is reduced.

The present invention has been made in view of the above-mentioned conventional circumstances, and manages information messages for each type based on title information, and further prevents unnecessary types of information messages from being stored and stored based on the title information. It is another object of the present invention to provide a message receiver capable of effectively utilizing a memory capacity. It should be noted that further specific objects of the present invention will be described in the following description.

[0008]

SUMMARY OF THE INVENTION A message receiver according to the present invention is implemented, for example, in a pager, wirelessly receives an individually selected call number and at least one group call number, and receives the received individually selected call number or group. If the call number matches the call number assigned to the self, the received message corresponding to the individually selected call number or the group call number is stored in the storage means and displayed on the display. In the present invention, in particular, in order to select an information message related to a group call of the common information providing service,
The storage permission / inhibition information which specifies whether the information message can be stored in the storage means is received from the input means, and the storage permission / inhibition information is held in the storage condition storage means so as to be rewritable for each title information, and corresponds to the group call number. If the title information of the information message wirelessly received is prohibited, the information message is discarded so as not to be stored in the storage means. This prevents information messages of a type that the user does not need to be stored and stored according to the setting of the storage availability information, thereby preventing wasteful consumption of memory capacity.

In the message receiver according to the present invention, the storage means has a title information storage area and an information message storage area, the title information portion of the information message is stored in the title information storage area, and the information message is stored in the title information storage area. The message contents are stored in the information message area, and the information message received by the storage means is automatically classified and stored in each storage area based on the title information. The storage condition storage means is composed of an area for holding a storage prohibition flag in the title storage area, and the storage availability information is a storage prohibition flag set for each title information in the title storage area, and The information message is not stored for the title information for which the storage prohibition flag is set.

Further, the message receiver according to the present invention has means for deleting from the storage means an information message area corresponding to the title information for which the storage prohibition flag has been set. Free up memory capacity and promote effective use of memory. In the message receiver according to the present invention, the title information includes the title and the subtitle, and the storage availability information is set and held for each title or each subtitle. As a result, the types of unnecessary information messages can be set finely, and the memory can be more effectively used.

Further, a message receiver according to the present invention comprises:
A message display unit for displaying and outputting the information message stored in the storage unit may be configured as a device having only the function of receiving and storing the message, and displaying the received information message on a separate display device. With this configuration, the user can easily display and output the received message. Also, the message receiver according to the present invention has storage condition display means for displaying and outputting the storage availability information held in the storage condition holding means in association with the title information, whereby the user can obtain the title information. The setting of the storage availability information for each can be easily and reliably performed while visually checking the display.

According to a preferred aspect of the present invention, when the individually selected call number and the group call number are received by radio and the received individually selected call number or the group call number coincides with the call number assigned to itself, The message received corresponding to the individually selected call number or the group call number is stored in a storage means, and is implemented as a message receiver such as a portable pager or the like displayed on a display. And a received information storage area for storing information messages received corresponding to the group call number. When the receiving means receives the group call number, the information message and the radio signal including the title information of the information message, the received group call number and the own group call number stored in the call number storage means are compared with the call number comparing means. Are compared. As a result, when they match, the title extracting means extracts title information from the received signal.
Then, the storage determining means determines whether or not the extracted title information is permitted to be stored based on the storability information stored in the storage condition storing means. As a result, the storage of the extracted title information is permitted. Only in such a case, the information message is extracted from the received signal, and the extracted title information and the information message are stored in the received information storage area of the storage means. As a result, the memory capacity of the message relating to the individually selected call is secured, the storage capacity of the message relating to the group call is effectively utilized, and the memory having a limited storage means so as not to interfere with the individually selected call and the group call. Utilize capacity.

Note that N1, N2, and N3 are code numbers assigned to the respective titles and subtitles, and the title and the subtitle are character strings such as a headline of the body content. This information title is used for automatically classifying and storing information messages as shown in FIG.

In the case of a normal message for an individual call, the signal type 242 indicates that the message is a normal message different from the information message, and the information message text field 246 is created by the caller. The message content is inserted. Such a normal message is handled as a different message from the information message by the pagers 6A to 6N, and is stored in a memory area reserved for storing the normal message as described later.

Next, a format example applied to the message field 24 of the information message in this example will be described with reference to FIG. In this example, there are three types of formats, and as shown in FIGS. 4A and 4B, an identifier 241, a signal type 242, a message serial number 243,
The information flag 244 is used commonly for each format. The format shown in FIG. 4A is composed of a title, a subtitle 1, a subtitle 2, their respective code numbers (N1 to N3), and an information body field 246 (hereinafter referred to as format 1). It is. The format shown in FIG. 4B is a format used when transmitting only a title (hereinafter, referred to as format 2), and is used for creating only a title, changing a title, deleting a title, and the like. The format shown in FIG.
When transmitting an information message of the same title, subtitle 1 and subtitle 2 as the format transmitted in (a), the contents of the title, subtitle 1 and subtitle 2 are omitted as title information and their code numbers (N1 ... N3) is a format for transmitting the information message body 246 (hereinafter, referred to as format 3), thereby reducing the amount of transmission data. In each of the above formats,
If the subtitles 1, 2 and N1, N2 are not included in the format, the information message body 246 is packed to the left.

In order for the pagers 6A to 6N to identify these three types of formats 1 to 3, the information flag 244 described above is used. Table 1 shows the configuration and operation of this information flag 244. Specifically, the information flag 244 has five functions. When the information flag 244 is “A”, it indicates format 1, when it is “B”, it indicates format 2, and when it is “C”, it is format 2. Further, it indicates the change of the title and subtitles 1 and 2 received by the pager.
In addition, it indicates the deletion of the title, subtitles 1 and 2 received by the pager and the body of the information message stored corresponding thereto, and format "E" indicates format 3.

[0023]

[Table 1]

FIG. 5 is a block diagram showing an embodiment of the pager (selective call receiver with display function) of the present embodiment. In the pagers 6A to 6N in this example, 60 is an antenna for receiving a radio signal, 61 is a receiving unit for receiving a radio signal of the above-described frame format transmitted from the base stations 5A to 5N via the antenna 60, 62 is A decoder section for decoding the received signal, 63 is an ID-ROM for storing a pre-assigned own call number, a group call number assigned for receiving the information message, and a frame number to be received, 64 is A ROM for storing various programs for controlling the functional unit, a RAM for storing a received message, a display driving circuit for driving a display unit based on an input signal from a control unit; 67 is a display unit such as an LCD for displaying a message or the like, 68 is an LED for notifying that a call has been made by light, 9 ringing such as a speaker for notifying by sounds that a call sound part 70 is vibrating part of the vibrator or the like for informing the vibrations that a call,
Reference numeral 71 denotes an operation unit for a user to read a message, stop a calling operation, and input storage availability information for each title information.

Here, the communication system of the present embodiment employs a diversity format in which data such as a message is redundantly transmitted in a plurality of frames.
3 stores the number of the frame to be received, and based on the number of the frame, each of the pagers 6A to 6N performs reception processing of the frame corresponding to itself. It should be noted that the present invention is not limited to such a type of communication system, and it is needless to say that the present invention can be realized in various other types of communication systems.

The pager has the above-described functional units 6.
A control unit 72 is provided for integrally controlling the control units 1 to 71.
The control unit 72 includes the address of the received signal and the ID-
ID comparing means 73 for comparing with the call number or group call number stored in the ROM 63; normal message extracting means 74 for extracting the next individual message when the received signal matches the individual call number; When the signal matches the group call number, title information for classifying and storing the next information message is extracted, and the extracted title information and the title information stored in the reception information storage area 81 and the storage availability information are stored. (In this example, a storage prohibition flag), a title information extracting unit 75 for creating a folder for storing an information message in the reception information storage area 81 according to the comparison result, and extracting the extracted title information and information message to the reception information. Folder creation means 76 for storing in storage area 81, including information message if storage is prohibited An information message discarding unit 77 for discarding a received signal; an information message extracting unit 78 for extracting an information message from the received signal when the received signal matches the group call number and storage is permitted; And a prohibition flag setting unit 79 for setting the storage availability information input from the reception information storage area 81 in a predetermined area portion as described later.

Further, the RAM 65 stores a normal message storage area 80 for storing a message corresponding to the individual call number and an information message transmitted in a format without title information, and an information message with title information. It is divided into a reception information storage area 81 for classifying and storing according to the title. Therefore, these areas 80 and 81 have independent memory capacity, and have a capacity for storing ordinary messages and the like.
The capacity for storing the information messages classified by the title is secured without being affected by the mutual consumption capacity. For example, even if an extremely large number of information messages are stored in the reception information storage area 81, the normal message storage is performed. The area 80 can store a normal individual call message without being affected by this. In this example, two areas are formed by dividing the same memory field, but these areas may be formed by different memory devices. Further, it is preferable to divide the two areas as described above, but it is not essential to divide the area in this way from another object of the present invention.

Next, with reference to FIG. 6, a description will be given of the concept of storage in a memory when information messages are hierarchically classified and stored. Here, a description will be given by taking two examples of the content of the information message following the group call number, news information and weather information. When storing the received information message, the pager called by the above-mentioned group call signal performs classification according to the title and subtitles 1 and 2 inserted in the message field 24, and stores a folder as a storage area corresponding to these. Create and save.

First, the case of information relating to news will be described. The title "news" and the title number "NO.1" attached to the above-mentioned information message are described.
Is created, and subtitles 1 "Japan" and this number "NO.1", "world" and this number "NO.2", "entertainment" and this number are used to classify this title in detail. "NO.3", "Sports" and this number "NO.4" are extracted and corresponding folders are created. Subtitle 1 "Japan" and "world" are further classified into subtitle 2 "politics" and this number "NO.1", "economy" and this number "NO.2".
Is created. Similarly, for “Sports” of subtitle 1, “baseball” of subtitle 2 and this number “NO.1”, “soccer” and this number “NO.2”, “golf” and this number “NO.3”
Is created.

Next, in the case of information relating to weather, similarly to news information, first, a title folder corresponding to the title "weather" and this title number "NO.2" is created. Subtitle 1 “Hokkaido” and this number “N” for classifying this title in detail
O. 1 "," Tohoku "and this number" NO. 2 ”,“ Kanto ”
And subtitle folders respectively corresponding to the numbers “NO. 3”. In order to classify “Kanto” in subfolder 1 in more detail, “Tokyo” in subfolder 2 and this number “NO.1”, “Chiba” and this number “NO.2”, “Kanagawa” and this The number “NO.
3 "," Saitama "and this number" NO. 4 ". The subtitle folders corresponding to the respective titles, subtitles 1 and 2 are created. Information messages belonging to the respective titles and subtitles 1 and 2 are stored in the created folders. You.

As described above, in this example, based on the title, a plurality of subtitles 1 are categorized under the title, and a plurality of subtitles 2 are further categorized under the subaddress 1 to correspond to these titles and subtitles 1 and 2. By creating a folder (storage area) for storing the information messages to be stored, the information message texts can be automatically hierarchically classified and stored.

FIGS. 7 and 8 show the configuration of the reception information storage area 81 for storing the information message shown in FIG. The reception information storage area 81 includes a title information storage area as shown in FIG. 7 and an information message storage area as shown in FIG. As shown in FIG. 7, the title information storage area includes a memory number, an area for storing hierarchical information indicating the level of the title information, and a storage prohibition indicating storage prohibition of an information message corresponding to the title information. An area for setting a flag, an area for storing the code numbers of the titles and subtitles 1 and 2 (three digits of the code numbers N1, N2, and N3 form an information code), and the title of the code are stored. And an area for it.

In this example, the storage prohibition flag is "0".
In the case of, indicates that the information message corresponding to the title information is stored in the information message storage area,
When the storage prohibition flag is “1”, it indicates that the information message corresponding to the title information is discarded without being stored. Here, although not included in the configuration shown in FIG. 5, in the present invention, the information message area corresponding to the title information for which the storage prohibition flag is set is represented by R
Means for deleting from the AM 65 may be provided in the control unit 72.

In the title information storage area, for example,
Title is "News" and title number N1 is "N"
O. When the title information of "1" is stored, "1" indicating the first layer in an empty area (here, memory number 1), and the information code (N1, N2, N3) is a code number in N1. For example, “0” that is not used for the code number is added to “1”, N2, and N3, and “1”, N2, and N3 are added to N1.
1 "," 0 "in N2," 0 "in N3 and" news "in title information, and the storage prohibition flag is set to" 0 "indicating that an information message relating to news is stored in the information message storage area. Also,
Subtitle 1 is “entertainment” and subtitle number is “3”
In the column of the memory number 8, "2" indicating the second hierarchy is shown in the hierarchy area, and the information code is the code number "1" of the title "news" to which the subtitle "entertainment" belongs in N1; N2 has the code number of “entertainment”
"3" and "N3" are stored in the title information and "entertainment" is stored in the title information, and the storage prohibition flag is set to "1" indicating that the information message relating to the entertainment is not stored in the information message storage area.

For the information having the subtitle 2 of "Saitama" and the subtitle number of "4", the memory number 20
, "3" indicating the third hierarchy, and "3" as the information code
The code number “2” of the title (weather) to which “Saitama” belongs
(N1) and code number of subtitle 1 (Kanto) "
3 "(N2) and the code number" 4 "of" Saitama "are stored," Saitama "is stored in the title information, and the storage prohibition flag indicates that an information message relating to news is stored in the information message storage area. 0 "is set. With such a configuration, the title and the subtitles 1 and 2 can be managed in a hierarchical manner with attributes, and the target information can be easily obtained in the subsequent reading processing or the like. Further, when the user performs a setting operation from the operation unit 71, the storage prohibition flag is rewritten, whereby the title information, which is a fine type for each layer such as a title and a subtitle, and is unnecessary for the user, is obtained. It can be arbitrarily set so that the information message relating to is not stored in the memory 65.

As shown in FIG. 8, the information message storage area has the code numbers 3 of N1, N2 and N3.
It is composed of an area for storing information codes with the same digits, an area for storing a number for distinguishing a folder for each information code, and an information message area for storing the contents of a received information message. Note that the above-described deletion processing in accordance with the setting of the prohibition flag is performed for each area for storing an information code in which the code number is made up of three digits. The memory capacity wasted on storing messages can be reduced.

The information message stored in the information message storage area stores an information message corresponding to the information code. For example, the code number is "141".
The information message storage area stores information messages related to “baseball” among news information corresponding to information code “111” managed in the third hierarchy and related to “sports”. Note that information messages are not stored for title information (for example, “soccer” and “Hokkaido”) for which the storage prohibition flag “1” in the title information storage area shown in FIG. 7 is set. An area for storing such an information message is not secured. With such a configuration, it is possible to store the information messages classified and classified by the title and the subtitles 1 and 2, and it is possible to easily find the target information in the subsequent reading processing or the like. Further, it is possible to omit an area for an information message that is not required by the user, thereby avoiding wasting memory capacity.

If the title information and the content part of the information message are divided into respective areas and managed in a hierarchical structure as in this example, the target information can be obtained by indexing the title information storage area. It can be easily searched and the corresponding information can be easily specified and read from the information message storage area. However, as long as the information message can be classified and managed based on the title information, the present invention is not limited until the title information and the content part of the information message are divided into respective areas and managed in a hierarchical structure as described above. Is not essential, and various other aspects can be adopted.

FIG. 9 shows an example of the setting process of the information message storage prohibition flag in the pager described above.
FIG. 10 shows an example of a screen displayed on the display unit 67 at the time of the setting operation. First, when an instruction to display title information is input from the operation unit 71, the control unit 72 causes the title information shown in FIG. 7 (specifically, as shown in FIG. "Weather") is read from the reception information area 81, and title information is displayed on the display section 67 (step S1). Next, in response to the selection operation of the operation unit 71, the control unit 72 causes the selected title among the title information displayed on the display drive circuit 66 to be shaded as shown in FIG. 10 (step S2), Further, it is determined whether the input instruction of the operation unit 71 is for inhibiting the storage of the information message corresponding to the selected title information or for permitting the storage (step S3). The title information to be displayed can be switched to a lower-level subtitle according to the selection operation of the operation unit 71 as shown in FIG.

If the input instruction is to prohibit the storage of the information message, the prohibition flag setting means 79 sets the storage prohibition flag "1" in the title information storage area (step S4), and stores the information message. If the input instruction is for permitting, the prohibition flag setting means 79
Sets the storage prohibition flag "0" in the title information storage area (step S5). More specifically, when the storage prohibition flag “1” is set, a display for prohibiting the information message regarding “Tohoku” of the weather is displayed on the display unit 67 as shown in FIG. Storage prohibition flag "
When “0” is set, a display for “receiving” an information message relating to the weather “Hokkaido” is displayed on the display section 67 as shown in FIG.

The setting of the storage prohibition flag is inverted in accordance with the operation of the operation unit 71, and the setting of the storage prohibition and the release thereof are arbitrarily performed by the user, and the setting state is as shown in FIG. The information is displayed on the display unit 67. The setting of the storage prohibition and the release thereof can be repeatedly performed by the user selecting the title information (step S6). As a result, the storage prohibition flag is set for each title information according to the operation of the user. Is set.

FIGS. 11 and 12 show an example of the reception processing operation in the pager described above. First, FIG.
In step 1, when the receiving unit 61 receives a frame including its own call number stored in the ID-ROM 63 (step S10), the call number in the address field 22 of the received frame and the frame stored in the ID-ROM 63 are stored. The comparison with the individual call number is performed by the ID comparison means 73 (step S11). If the two do not match as a result of the comparison, the processing after A in FIG. On the other hand, if they match, the control unit 72 determines whether or not there is a message with reference to the following vector field 23 (step S12). If there is a message, the received message is sent to the normal message extracting means 74.
And stores it in the normal message storage area 80 (step S13), controls the display drive circuit 66 to display the message on the display 67 (step S14), and furthermore, the LED 68 and the sound generator 69. Alternatively, an operation of informing that a call has been made is performed by the vibration unit 70 (step S15). If there is no message in step S12, only that there is a call is LE
D, a notification is given by a sounding unit or a vibrating unit (step S
15).

If the received call number and the own call number do not match as described above (step S11),
The processing shown in FIG. 12 is performed. First, the receiving call number and I
The ID comparing means 73 compares the number with the group call number stored in the D-ROM 63 (step S16). If the two do not match, the process proceeds to B in FIG. 11 to end the receiving operation.

The information message extracting means 78 extracts an information message following the title information in the received signal and stores the information message in the folder (step S22).

On the other hand, if the received title information matches the stored title information (step S17), a storage prohibition flag indicates whether or not the matched title information indicates that the storage of the information message is prohibited. (Step S20), and if the title is a storage prohibition title, the information message discarding means 77 discards the received signal including the information message (step S2).
1). On the other hand, when the received title is not the storage prohibition title, the information message following the title information in the received signal is extracted by the information message extracting means 78,
The information is stored in the information message storage area 81 (step S22), and the display drive circuit 66 is controlled to
7 is displayed (step S23).
Further, a notification operation is performed by the LED 68, the sounding unit 69 or the vibrating unit 70 to notify that there is a call (step S2
4), proceed to B in FIG. 11 and end the receiving operation.

In the above description, storage permission / inhibition information in the form of a flag is shown. For example, title information for which storage is prohibited or title information for which storage is permitted is stored in a memory, and the title information and the reception information are stored. The received information message may be discarded or stored by judging the coincidence with the title information. In the above description, an example in which the present invention is applied to a pager is shown. However, the present invention is not limited to a pager, and has a function of receiving information.
The present invention can be implemented in various forms such as a personal computer, a radio receiver, and a mobile phone.
