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 and storing a message addressed to itself by radio, and more particularly, to a storage means for storing a received message in accordance with a specific code set for each message receiver. The present invention relates to a message receiver that is not 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, if the received message is an information message related to service information, if the call numbers match, the message is stored in the memory.

[0004]

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 necessary messages is reduced.

[0005] Further, in the conventional message receiver, it is not possible to set the reception permission to the user according to the type of the information message among the information messages having the same group call number. There has been a problem that the distribution state of the information message cannot be set for each user in detail. Further, in the conventional message receiver, even if various service information from the information provider is received, the service information (information message) is stored in the same memory area as a normal individual message addressed to an individual. When the memory capacity for storing individual messages is reduced and many information messages are stored and held, there is also a problem that even when individual messages are received, they cannot be stored and displayed. .

The present invention has been made in view of the above-mentioned conventional circumstances, and further manages information messages based on a specific code, prevents information messages from being stored and stored by the specific code, and makes effective use of memory capacity. It is an object of the present invention to provide a message receiver.
It should be noted that further specific objects of the present invention will be described in the following description.

[0007]

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,
A specific code that defines whether or not the information message can be stored in the storage unit is stored and held in the specific code storage unit in advance,
When the specific code added to the information message wirelessly received corresponding to the group call number matches the specific code stored and stored, the information message is stored in the storage means. This prevents the information messages from being stored and stored according to the setting of the specific code that further subdivides the group call number, thereby preventing unnecessary consumption of memory capacity.

In the message receiver according to the present invention, in addition to the setting by the supply source of the receiver, a specific code arbitrarily input by the user for selecting an information message is accepted from the input means. The specific code is rewritably stored in the specific code storage unit. This prevents information messages of a type that the user does not need to store and store according to the setting of the specific code, thereby preventing wasteful consumption of memory capacity.

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.

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 matches the call number assigned to the self, 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 a radio signal including the group call number, the information message, and the specific code, the call number comparing means compares the received group call number with its own group call number stored in the call number storage means. As a result, when the two match, the specific code extracting means extracts the specific code from the received signal. Then, the specific code comparing unit determines whether the specific code stored in the specific code storage unit and the extracted specific code match. As a result, only when the two match, the storage unit outputs the received signal. Is stored in the received information storage area of the storage means. As a result, the storage capacity of the message related to the individually selected call is secured, the storage capacity of the message related to the group call is effectively used, and the storage means is limited so as not to hinder the individually selected call and the group call. Take advantage of memory capacity.

In the specific code storage area 78, a plurality of specific codes input by the operation unit 77 and a title corresponding to the specific code are rewritably stored. For example, the specific code "2"
001 "and the title" Japanese political news "are stored. When a group call signal including the specific code" 001 "is received, an information message included in the signal is stored in the reception information storage area 79. Here, in this example, since the information message also includes the title information, the corresponding title information is also stored in the specific code storage unit 78. However, in the present invention, Alternatively, only the specific code may be stored in the specific code storage unit 78.

FIG. 6 shows a configuration of a reception information storage area 79 for storing an information message. In the information message storage area, when the group call number and the specific code match, the matched specific code and the information message (message content) transmitted with the specific code added are rewritably stored in the order of reception. You. For example, the content of the information message “message about (sports)” transmitted with the specific code “022” added as the reception number “3” is stored, and at the time of reception and input of a display instruction from the operation unit 71. The contents of these stored messages are displayed and output from the display unit 67. In this example, the specific code extracted from the received signal is also stored in the reception information storage area 79. However, storing the specific code is not essential in the present invention.

FIG. 7 shows an example of the reception processing operation in the pager described above. First, the receiving unit 61
When a frame including its own call number stored in the ROM 63 is received (step S1), the call number and the ID-R in the address field 22 of the received frame are received.
The comparison with the individual call number stored in OM63 is ID
The comparison is performed by the comparing means 73 (step S2). If the two do not match as a result of the comparison, the processing from step S7 described later is performed. 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 S3). If there is a message, the message is extracted from the received frame by the normal message extracting means 77 and stored in the normal message storage area 80 (step S4), and the display drive circuit 66 is controlled to display the display section 67. Is displayed at step S5.
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 S6).
If there is no message in step S3,
Only the call is notified by the LED, the sounding unit or the vibrating unit (step S6).

If the received call number does not match its own individual call number (step S2) as described above, first, the comparison between the received call number and the group call number stored in the ID-ROM 63 is made by ID. The comparing means 73 performs the operation (step S7). If the two do not match, the receiving operation ends. On the other hand, if they match, the control unit 72 determines whether or not there is an information message by referring to the following vector field 23 (step S8). To end. On the other hand, when the information message is present, the specific code extracting unit 74 checks whether or not the specific code 241 exists in the received frame (step S9).
If 1 does not exist, the receiving operation ends.

On the other hand, if the specific code 241 exists, the specific code extracting means 74 extracts the specific code from the received frame, and the extracted specific code and the specific code registered in the specific code storage means 78 in advance. Is compared by the specific code comparing means 75 (step S10).
As a result, if the two do not match, the group call number matches in this pager, but it is not an information message permitted to be stored, so that the next information message is received without being extracted and stored in the memory. The process ends.
On the other hand, if they match, the information message extracting means 76 extracts the next information message in the received frame, stores it in the received information storage area 79, displays the received information message (step S5), and calls Is notified (step S6).

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 the pager, and has a function of receiving information, for example, a personal computer, a radio receiver, a portable telephone, etc. It can also be implemented in various forms.

[0027]
