Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a radio paging receiver and a radio paging method for receiving and displaying a message sent from a transmission side together with a paging request, and more specifically to a message memory management and notification means from the transmission side. The present invention relates to a radio call receiver and a radio call method capable of designating.

[0002]

2. Description of the Related Art In a conventional general radio paging receiver, messages sent from a sender are stored in a message memory in the order of reception time, and new messages can be displayed in order. In such a receiver, when the message memory is full, new messages are deleted in the order of oldest reception time, and new messages are stored.

[0003]

By the way, depending on the genre of the message, only the latest message has meaning, and the past message does not have meaning (for example,
Weather forecast). If the number of messages that can be stored in the message memory (the number of messages in the message memory below) is small, if you receive many such meaningless messages, you cannot store messages of other genres, There was a risk that messages of a few genres would be overwritten. Further, even if the number of message memories is large, if many meaningless messages are stored, it becomes difficult to see the necessary messages.

On the other hand, in this type of receiver, the arrival of a message is informed by an informing means (for example, a sound, a vibrator, etc.), but conventionally, the setting of the informing means (incoming call notification or non-incoming notification) is addressed. Since it could be done only on a unit basis, the user could not know whether the message was of high urgency or importance unless the contents of the received message were confirmed each time. Also, the urgency
If the incoming call is notified only for a highly important message, it becomes impossible to notify the incoming of a normal message, which causes a problem that the user has to periodically see the message.

A first object of the present invention is to provide a radio paging receiver and a paging method capable of appropriately allocating memory for each genre by performing message memory management according to the intention of the transmitting side. is there.

A second object is a radio paging receiver and a paging method by which a user can easily know a message of high urgency / importance by designating a notification means for informing that a message has arrived. To provide.

[0007]

In order to achieve the above first object , the first feature of the present invention is to provide a receiving means for receiving a message transmitted with a radio call signal, and information of the received message. A radio paging receiver comprising: processing means for hierarchically processing the storage and display of the text according to the information regarding the hierarchical structure added to the message,
The processing means determines whether or not the received message includes a predetermined message sequence number indicating that the message is a message to be overwritten, and if the predetermined message sequence number is included, the reception process is performed. The gist of the message is to overwrite the message having the same message serial number as the message.

[0008] The first feature of the present invention, the processing means, when the message sequence number contained in the received message is a specific number range, overridden for message with the same message sequence number Is configured to not overwrite if not within the specified number range.
May be .

[0009] The first feature of the present invention, the processing means, whether to overwrite against messages with the same message sequence number, is configured to control based on the choice of the user May be .

A second feature of the present invention is that a message to be transmitted to a radio paging receiver is added with information regarding a hierarchical structure indicating that the storage and display of the information body of the message is hierarchically processed. In the wireless paging method, the wireless paging receiver hierarchically processes the storage and display of the information body of the received message in accordance with the information regarding the hierarchical structure added to the message. When the message is a message to be overwritten, a predetermined message sequence number indicating that the message is to be overwritten is added and transmitted,
The gist of the radio paging receiver is to overwrite the received message with a message having the same message sequence number as the message when the predetermined message sequence number is added to the received message. .

A second feature of the present invention is that, when a message sequence number included in a received message is within a specific number range, the message having the same message sequence number is overwritten, and It may be configured not to overwrite when the number is out of the range.

In order to achieve the second object, the present invention
A third feature of the present invention is that the receiving means for receiving the message transmitted with the radio paging signal and the storage and display of the information body of the received message are hierarchically arranged according to the information regarding the hierarchical structure added to the message. In a radio paging receiver provided with a processing means for processing, the processing means has a predetermined message indicating that the received message is a message to be notified by a notification means different from a normal message notification means. The gist is to determine whether a message serial number is included, and if the predetermined message serial number is included, to notify the message by a notification unit different from the normal message notification unit.

[0013] The third aspect of the present invention, the processing means, the notification means of normal messages is configured whether to notify the different notification means, so as to control based on the choice of the user May be .

The fourth feature of the present invention is to add information regarding a hierarchical structure to a message to be transmitted to a radio paging receiver, which indicates that the information body of the message is stored and displayed hierarchically. In the wireless paging method, the wireless paging receiver hierarchically processes the storage and display of the information body of the received message in accordance with the information regarding the hierarchical structure added to the message. When the message is a message to be notified by a notification unit different from the notification unit of the normal message, a predetermined message indicating that the message is a message to be notified by a notification unit different from the notification unit of the normal message The radio paging receiver adds the serial number to the message and adds the predetermined message serial number to the received message. If they are, and summarized in that informing the different notification means a notification means a regular message the received message.

BEST MODE FOR CARRYING OUT THE INVENTION An embodiment of a radio paging receiver to which a radio paging receiver and a radio paging method according to the present invention are applied will be described below.

FIG. 1 is a block diagram showing the functional configuration of a radio paging receiver 10 according to this embodiment.

The radio paging receiver 10 receives a message (signal) transmitted from a base station (not shown) installed by a radio paging service provider, and a message received by the reception unit 1. A message processing unit 2 for storing and displaying a message, a memory 3 for storing a message information body, a display unit 4 for displaying the stored information body, a ringing sound for receiving a message, a vibrator, silent, etc. The notification unit 5 notifies the user by the notification unit, and the operation unit 6 allows the user to manually set the operation.

The message processing unit 2 hierarchically processes the storage and display of the information body of the message according to the information about the hierarchical structure added to the received message.

Here, the hierarchical processing of the received message will be described. FIG. 2 is an explanatory diagram showing an example of the hierarchical structure of the information text stored in the memory 3 of FIG. In the figure, message XX indicates the order of message reception.

In FIG. 2, folders with the titles "News" and "Weather" are provided at the highest level (Level 1) of the address, and "Sports" is provided below the "News" item (Level 2). "And" politics / economy "is" weather "
Under the item, there are folders titled "Tomorrow's weather" and "Weekly forecast", respectively. Also,
Below the “sports” item (level 3), folders with the titles “baseball” and “soccer” are further provided. The information body of the received message is stored according to this folder and can be displayed on the display unit 4 according to this folder.

Next, the process of storing the received message in the message processing unit 2 will be described.

The message processing unit 2 determines whether the received message includes a predetermined message sequence number indicating that the message is a message to be overwritten. If the received message includes the predetermined message sequence number, , Process the received message so that it overwrites the message with the same message serial number as that message.

To set a predetermined message sequence number indicating that the message should be overwritten, the message processing unit 2 of this embodiment sets the message sequence number to 2 as described later.
The message is divided into two groups, and the message with the larger group number is overwritten, and the message with the smaller group number is not overwritten.

Further, the message overwrite processing in the message processing unit 2 can be arbitrarily selected by the user. That is, when the user selects either overwriting or not overwriting in the message processing unit 2 through the operation unit 6, the above-described message overwriting process can be controlled based on this selection. In this case, if the user selects not to overwrite, the message will not be overwritten regardless of what message serial number is added to the message.

Further, the message processing unit 2 checks whether the received message includes a predetermined message sequence number indicating that the message is a message to be notified by a notification means different from the normal message notification means. If it is determined that the predetermined message serial number is included, the operation of the notification unit 5 is controlled so that the received message is notified by a notification unit different from the normal message notification unit. Also in this case, the user can arbitrarily select the notification means in the notification unit 6. That is, the user selects either the normal notification means or the different notification means as the notification means in the notification unit 5,
The operation of the notification unit 5 by the message processing unit 2 can be controlled based on the selection by the user.

When overwriting a message, the message sequence number is divided into two groups, and it is distinguished whether the message is overwritten or not depending on the size of the group number. If a message sequence number of a message to be notified by a notification unit different from the normal notification unit is set in advance, and if the sending side determines that the message has high urgency / importance, the message serial number is added. It is possible to notify the receiver side at the same time of the information that the message is overwritten with one message sequence number and the information that the notifying means is the normal notifying means / the different notifying means.

Next, the basic format of the message will be described. FIG. 3 is an explanatory diagram showing a format example of a message suitable for use in the operation example of this embodiment. FIG. 4 is an explanatory diagram showing a configuration example of a message based on the format, and FIG. 5 is an explanatory diagram showing a specific example of the message.

As shown in FIG. 3, the message 11 includes
As a minimum required information element, an identifier 21 indicating that the message relates to hierarchical processing, a message sequence number 22 indicating individual information for each message,
It includes four types, a title group 23 indicating the storage position of each message in the hierarchical structure and an information body 24 to be stored at the hierarchical position.

The identifier 21 is a single symbol or character,
A plurality of symbols or characters, or a mixture thereof may be used. This identifier 21 must be agreed in advance between both the sender (sender of information) and the receiver (receiver). When a single symbol or character is used, the maximum number of transmittable digits is determined by the radio paging service. Therefore, the shorter the identifier 21 is, the larger the capacity of the information body 13 can be. However, misidentification may occur. On the other hand, if multiple symbols or character strings are used, the possibility of misidentification will be reduced, but the upper limit of the maximum transmittable message length is limited for each service being operated, so the information will be increased accordingly. Body 13
Capacity is reduced. In FIG. 4, the symbol "}" is used as this identifier.

The message serial number 22 represents the following two pieces of information as individual information for the message. One is information necessary for linking the message ID and the divided message. The message serial number "NNM" shown in FIG.
“L” indicates NN: message ID, M: serial number of divided message, and L: number of divided messages. With these pieces of information, the divided messages on the transmission side can be concatenated as one integrated message.

The other is information indicating whether the message is a message to be overwritten. In this embodiment, message serial numbers are divided into two groups,
The message with the larger group number (5000 to) overwrites the other message with the same message number, and overwrites the message with the smaller group number (to 4999). Controlled not to do. Note that the grouping of message serial numbers is not limited to this example, but can be set as appropriate.

The title group 23 is composed of "title characters" 233 indicating the titles of the respective layers shown in FIG. In order to easily identify the position of each layer, a “management code” 232
Can also be used together. Also, in order to separate each layer, a “delimiter” 234 with a predetermined code is used.
Can also be used. When the “title character” 233 has a fixed length, the “delimiter” 234 is unnecessary. In addition, it is possible to use the “number of layers” 231 that specifies the number of layers, but it is possible to identify by the number of “delimiters” 234, or to set the “title character” 233 as a fixed length (fill insufficient blank characters). The number of layers can be identified by the element length. FIG. 4 shows a case where the title character has a fixed length and the delimiter and the management code are not used. "|"
Is a delimiter between the title group 23 and the information body 24, which makes it possible to determine the designated number of layers.

Next, the operation of the radio paging receiver 10 when it receives a message in the above format will be described with reference to the flowchart of FIG. In this example, the group number of the message sequence number to be overwritten is X to
And

When the receiving unit 1 receives the message (YES in step 101), the message processing unit 2
First, the identifier is detected (step 102). If there is no identifier (NO in step 102), the message is discarded or processed in the order of reception (step 103). When the identifier is detected (YES in step 102), the title group is extracted (step 104) and the hierarchical structure corresponding to the title group is detected (step 105).
If there is no corresponding hierarchical structure, the hierarchical structure is added (step 106). Adding a hierarchical structure means creating a new hierarchical structure on the receiver side when there is no hierarchical structure corresponding to the received message.

Next, the information body is detected (step 1
07), if not present, the process ends. If there is the information body (YES in step 107), then the message sequence number is detected (step 108). If there is a message sequence number (YES in step 108), then it is determined whether or not the message number is larger than X. (Step 10
9). If the message number is greater than X (step 1
(YES in 09), it is determined whether or not there is a message with the same message sequence number in the same hierarchical position in the memory 3 (step 110). If there is a corresponding message (YES in step 110), the same message is determined. Overwriting is completed by deleting the message with the serial number and storing a new message in the same storage destination (step 111). Storing a new message in the same storage destination means storing a new message in the storage position of the deleted message.

On the other hand, when there is no message sequence number in step 108, when the message number is smaller than X in step 109, and when there is no message with the same message sequence number in step 110, according to the title group attached to the message. , The information body is stored in the corresponding hierarchical position (step 112). Storing the information body in the corresponding hierarchical position means storing in the hierarchical position in the order of the reception time.

After step 103, step 111 or step 112, the process returns to step 101 to move to the next message.

Next, a specific example of the above-mentioned receiving operation will be described. 7 to 9 schematically show the inside of the message memory at a certain address, and here it is assumed that genres A to C are in the same hierarchy.

In the conventional radio paging receiver, received messages are stored in the message memory in the order of reception time. When the message memory is full, the message with the oldest reception time is erased and a new message is stored in the order of reception time. I am trying. If the proportion of messages transmitted is equal for each genre, new messages are equally stored for each genre, as shown in FIGS. 7 to 8, so that messages are evenly distributed for each genre. It will be. However, as shown in FIG. 9, when only messages of a certain specific genre (genre B in this case) are received, old messages are deleted in the order of the reception time, so that the message of that address finally becomes Only messages of a specific genre will be displayed. Therefore, the user who views the message at that time recognizes that messages of other genres are not transmitted.

On the other hand, in the radio paging receiver of this embodiment, when a message is transmitted, the message sequence number of the message to be overwritten is set to 5000 to 500, so that a message including the same message sequence number as the message sequence number is transmitted. It can be controlled to overwrite only. For example, when messages 11 and 12 are newly received in the message memory of FIG. 7, the message 11 is overwritten on the message 2 having the same message sequence number (5200) as shown in FIG. 10, and the message 12 is the same. Message 5 with the message serial number (5500)
Is overwritten. As a result, as shown in FIG. 11, the number of messages stored in the genre B does not increase, and even if many new messages for the genre B are received thereafter, as shown in FIG. Message does not end up being a genre B message only.

As described above, by adding a message sequence number indicating that the message should be overwritten to a specific message and transmitting the message, the intention of the transmitting side is not affected by the transmission frequency of each genre. It becomes possible to manage the message memory according to the above, and it becomes possible to appropriately allocate the memory for each genre and effectively use the message memory.

In particular, since the message serial number is used to determine whether the message is overwritten or not, the amount of information of the message is smaller than that in the case of adding control information for determining the processing for the message. can do. Also, since it becomes possible for the sender to manage whether or not to leave a message in the memory, it is more flexible than when only the latest message for each genre is left, regardless of the intention of the sender. It is possible to manage the message memory effectively.

The effective use of the message memory will be specifically described. For example, when the number of message memories at the addresses shown in FIG. 2 is 1000, the number of messages sent per day is about 50, and the message is received. If you do not delete the message, tomorrow's weather (1
The date: 1) contains a meaningless forecast for the past 20 days, making it difficult to read the message. In addition, when the number of messages in the message memory is only about 50, if many such messages are received, messages of other genres cannot be stored, and messages of genres that are rarely sent are overwritten. Will occur.

However, if the message of tomorrow's weather is sent with a message sequence number indicating that it is a message to be overwritten, the message is always overwritten, so that it will be included in many meaningless messages. Messages are easier to read because the necessary messages are not buried. Also, when the number of message memories is small, messages of other genres cannot be stored, and messages of genres with low transmission frequency are not overwritten.

When the message sequence numbers are divided into two groups as in this embodiment, when a message is transmitted, a message to be overwritten and a message not to be overwritten can be mixed.

FIG. 12 is an explanatory diagram showing another specific example of the message memory management. When sending the progress of a match between team A and team B to a baseball folder, the messages are usually stored in the order of reception time. When all the messages are stored in the message memory, there is no problem for the user who wants to know all the results including the progress, but it becomes difficult for the user who wants to know only the latest result.

In such a case, the transmitting side adds a message serial number to all the messages to indicate that the message should be overwritten and transmits the message. On the other hand, among the users on the receiver side, I would like to know the progress (I want to keep it)
The user can leave the match result by setting the overwrite prohibition. Further, a user who wants to know only the latest result can set only the desired result by setting the overwrite possible. Therefore, on the transmitting side, it is possible to manage the message memory according to the purpose of the user with the same message without changing the transmission content for each user.

Next, a specific example of the message notifying means in the radio paging receiver of this embodiment will be described.

The notification unit 5 shown in FIG. 1 notifies the reception of a message by a notification means such as a sound or a vibrator. For example, general news is sent to a political / economic folder. In such cases, since many messages are received in one of these genres per day, the notification means is usually set to silent or non-notification of incoming calls, and the messages are often collectively viewed later. However, some news has a high degree of importance such as rapid exchange rate fluctuations and incidents / accidents, and there are also messages that the user should know as soon as possible.

In such a case, a predetermined message sequence number indicating that the message is a message to be notified by a notification means different from the normal message notification means is added to the message considered important on the transmission side. Send. On the other hand, the message processing unit 2 on the receiver side
Detects a predetermined message sequence number in the received message indicating that the message is a message to be notified by a notification means different from the notification means for a normal message, controls the operation of the notification unit 5, and receives the message. The notified message is notified by a notification means different from the normal message notification means.

For example, when silent or non-notification of an incoming message is set for a normal message, if the sound is emitted or a vibrator is issued, the notification means different from the normal message alerting means is used. Therefore, the user can know that the message is of high urgency and importance. In addition, if a ringing tone or a vibrator is set to notify you of an incoming normal message, you can decide in advance another ringing tone pattern when you receive a message of high urgency / importance. , Depending on the sound pattern,
The user can know that the received message is an urgent / important message. Therefore,
In the receiver of this embodiment, it is possible to notify the user of the arrival of a normal message and at the same time reliably notify the user of the arrival of a message of high urgency / importance.

Next, another specific example of the message notifying means in the radio paging receiver of this embodiment will be described.

In the above-mentioned control of the notification means, a message judged to be important on the transmission side is notified by a notification means different from the ordinary one. Can be disadvantageous. For example, for team A (baseball) fans, it is important that the game is reversed, and there is no problem if the incoming call is notified as a message of high urgency and importance. However, for those who are not interested in baseball,
It is possible that the message I saw as a message of high urgency / importance was the result of baseball that I was not interested in.

In such a case, on the receiver side, the received message includes a predetermined message sequence number indicating that the message is a message to be notified by a notification means different from the notification means for a normal message. However, by setting the notification by the normal message notification means, the user will not be bothered to receive a message that is not urgent or important. Therefore, on the transmitting side, it is possible to manage the message memory according to the purpose of the user with the same message without changing the transmission content for each user.

In particular, since the notification means is selected using the message serial number, the amount of information in the message can be reduced as compared with the case where control information for designating the notification means is added.

[0056]

As described above, according to the radio paging receiver and the paging method according to the present invention, it is possible to manage the message memory according to the intention of the transmitting side. Allocation is possible. Further, since the sending side can specify the notification means when a message arrives, the user can easily know a message of high urgency and importance.

In particular, the receiving side can overwrite the message /
If the use / non-use of the notification means that is not possible and that is different from usual is controlled based on the user's selection, the purpose of the user is the same message without changing the transmission content on the transmission side for each user. It is possible to manage the message memory according to.
