Abstract

A newly received message is compared with formerly received messages which are stored in a memory. At the time of arrival of the newly received message, a portion of the message that is unchanged as compared to a formerly received message is displayed in a normal manner. Changed message portions may be displayed in different colours in order to highlight changing information such as rising or falling share prices. The colour of message portions may also be determined in relation to times of arrival and reading of messages.

Description

2352938 WIRELESS COMMUNICATION APPARATUS AND METHOD FOR DISPLAYING A

MESSAGE USED IN THE APPARATUS

FIELD OF THE INVENTION

The invention relates to a wireless communication apparatus and a method f or displaying a message used in the same, and especially to a wireless communication apparatus for displaying information transmitted f rom a base station and a method f or displaying a message used in the same.

BACKGROUND OF THE INVENTION

Hitherto, according to a wireless communication apparatus, a paging receiver for instance, a user can receive information on a hourly changing price of a stock at predetermined times or a certain interval if he desires.

In the paging receiver, if the price of the stock is displayed unchanged, the user cannot recognize a relation between information of the price of the stock newly displayed and that formerly displayed.

According to a paging receiver disclosed in Japanese patent application, laid-open, No. 10-304418, when..a receiving means 61 receives a message, a message-processor 66 compares the newlyreceived message with the formerly received message which has been 25 stored in a message-memory means 62.,as shown in FIG.1. When a dif f erence therebetween satisfies a predetermined condition stored in a condition inf ormation-memory means 65, an outputcontrol means 64 so controls an output means 63 that the newly received message is displayed in a reversal color.

For example, as shown in FIG.2A, if a message that a price of an issue YYY is "100" and that of an issue ZZZ is "8011 is received, the received message A is outputted to the output means 63, and stored in the message-memory means 62. Thereafter, a message 13 that the price of the issue YYY is 11150" and that of the issue ZZZ is 1180" is received by the receiving means 61. The message -processor 66 compares the message A with the message B. As a result, it becomes clear that, though the price of the issue YYY increases from - 100" to "150" and the difference therebetween is 11+5011, the price of the issue ZZZ remains "80" and the difference therebetween is 11011. When the condition information-memor'y means 65 stores"the difference is more than +201, as a condition, since the issue YYY contained in the message B newly received satisfies this condition, the price of the issue contained in the message B is displayed in a reversal color as shown in FIG.2B.

However, in the aforementioned paging receiver, since a specif i ed portion of the received message is merely displayed in a reversal color when a predetermined condition is satisfied, although the user can recognise that information displayed in a reversal color satisfies the predetermined condition, he cannot know the difference between the newly received message and the formerly received message, that is to say, an extent of increase ordecreaseof theprice. When the user desires detailed information, he must expressly press a scrawl button to read the messages received in the past.

DESCRIPTION OF THE PREFERRED EMBODIMENTS

Thereafter, preferred embodiments of the invention will be explained referring to the appended drawings.

FIG. 3 shows a block diagram for showing an internal structure of a wireless communication apparatus, or desirably a paging receiver, according to the first preferred embodiment of the invention.

In FIG. 3, a receiver 2 receives a wireless signal transmitted from a base station ( not shown) via an antenna 1, and demodulates it. A decoder 3 decodes the wireless signal demodulated by the receiver 2, and outputs a decoded signal to a CPU4 as a digital 15 signal. An EEPROM 5 previously stores one or more individual IDs, and one or more Lnformation IDs. The individual ID is a calling-up number assigned to an individual user, and the information ID is a common calling-up number assigned to an information service. The CPU 4 judges whether the ID contained in the digital signal coincides with the individual ID or the information ID stored in the EEPROM 5. In case that the ID contained in the digital signal coincides with the ID stored in the EEPROM 5, the CPU 4 controls a notification unit 6 to notify the user that the message has been received, and controls a LCD controller 7 to display the message contained in the digital signal on a LCD 8. Moreover, the CPU 4 stores the received messages in the RAM 9 for each ID. The RAM 9 stores the newest message of each information ID as well as the plural messages of each individual ID. Accordingly, whenever the message of the information ID is newly received, the message of the information ID stored in the RAM 9 is overwritten by the newly received message. When the message is received, the RAM 9 stores the time of reception of the message as a time-stamp data for each information ID on the 5 basis of the time counted by a clock 21.

ROM 10 previously stores display information such as fonts of characters to be displayed on the LCD 8 through the LCD controller 7 as well as a program for controlling the CPU 4.

It is desirable that the decoder 3, the CPU 4, the EEPROM5, the LCD controller 7, the RAM 9 and the ROM 10 are integrated on the same chip.

The notification unit 6, which notifies the user that the message of the individual ID or the information ID has been received, is desirably formed of a loudspeaker, a LED or a vibrator. The user can previously select whether he is notified of the arrival of the message by means of the notification unit 6 or not.

Particularly, since the message of the information ID is received at a predetermined interval in most cases and the number of times of arrivals of the messages of the information ID is comparatively larger than those of the individual ID, it is desirable that the notification unit 6 is so set that it does not operate in case that it receives the message of the information ID. The LCD 8 displays information on the present time and a menu of various functions as well as the received message, and may be replaced with a CRT.

When the user desires to read the received. message stored in the RAM 9 on the LCD 8, he operates a read switch 11. A reset switch 12 is operated by the user when notification by the notification unit 6, or display of the received message on the LCD 8, is stopped. A selective switch 13 is operated by the user when various functions and information are selected or the mode of notification-is changed.

In the invention, the RAM 9 comprises a memory for storing the received messages f or each ID, a primary buf f er f or temporarily storing a newly received message of the information ID, which will be mentioned in detail af terward, an operation buf f er f or computing a dif f erence between a previously stored message of theinformation ID and the same stored in the primary buffer, a table for replacing the result of the aforementioned computation with specif ic information,a. memory for storing the specific inforrdation, and a table for replacing the specific information with a color to be used for displaying the message.

FIG.4 is a diagram for showing internal tables of the RAM 9 shown in FIG.3.

In FIG. 4, the first memory domain ( memory A, hereinafter stores the messages of the individual ID for each individual ID. Moreover, Memory A stores a program for controlling the CPU 4, the individual IDs and the information IDs. The second memory domain ( Memory B, hereinafter) stores the newest message for each information ID. Moreover, Memory B stores a time-stamp data for each ID. FIG.4 shows a case where the paging receiver deals with three information IDs (ID1, ID2 and ID3). The primary buffer temporarily stores a newly received message of the information ID.

The operation buffer A computes the difference between the message of the information ID stored in Memory B and the newly received message of the same information ID which is stored in the primary buffer. The third memory domain (Memory C, hereinafter) stores information as to which portions of the received message are to be displayed and which colors are to be used for displaying the specified portions of the message, and is provided for each ID stored in Memory B. Accordingly, Memory C is provided for each 5 of three informations IDs (ID1, ID2 and ID3) in this embodiment.

A table B is a conversion table for determining a color to be used for displaying the specified portion of the message on the basis of substituted values stored in Memory C when the message stored in memory B is displayed. Other domains are used for storing information other than those used for display- control, such as a program, which is temporarily stored to be supplied to the CPU from the ROM, and information on notification, for instance.

Next, an example of operation of the paging receiver shown in FIG. 3 at the time of the arrival of a message will be explained referring to FIG.5 to FIGs.7A and 7B.

In FIG.5, when a power-supply is turned on, in other words, the paging receiver is standing-by ready to receive a message, it is judged whether a call is detected or not (step 202). If the call is detected (YES in stop 202), it is judged whether the message newly-received is a message of an individual ID or that of an information ID (step 203).

When the received message is judged to be the message of the individual ID ( NO in step 203), the received message is stored in Memory A in RAM 9 ( step 214. Then, the notification unit 6 notifies that the call is detected ( step 215 and the received message is displayed on the LCD 8 ( step 216) When a predetermined time, 20 sec for instance, has passed or the reset switch 12 is operated by the user, notification of the notification unit 6 and display of the received message on the LCD 8 are stopped ( step 217), and the state of standby is recovered.

On the other hand, when the received message is judged to be the message of the information ID ( YES in Step 203 as shown in FIG. 6A, the received message is temporarily stored in the primary buffer (step 204). In this case, if another message has been already stored in the primary buf f er, the primary buf f er is overwritten by the newly-received message Moreover, memory C in RAM 9 is initialized, and data in all memory addresses become "0" (step 205).

An initialization in Memory C in step 205 is not necessarily conducted. When data is written into Memory C as mentioned later, other data already stored therein is overwritten by the data to be stored.

FIG. 6A shows a state where a message "a a (222) 9 9 (333) " is newly-received when the received message 'Ice a (105) 9 9 (333) has been already stored in Memory B In this embodiment,, it is previously clear that data stored in memory addresses 3 to 5 are numerical data. After Memory C is initialized, a newly received message which is temporarily stored in the primary buffer is compared with the message already stored in Memory B ( step 206) and it is judged whether there is a difference between the two aforementioned messages or not (step 207).

When it is judged that there is a difference between the two aforementioned messages (YES in step 207 the difference between the newly received message which is temporarily stored in the primary buffer and the received message which is already stored in Memory B is respectively computed with respect to predetermined portions, 12- which are contained in brackets (step 212 In an example shown in FIG. 6A, the dif f erence is given by "222" - "10511="117" in memory addresses 3 to 5, and the difference "117" is stored in memory addresses 3 to 5 of the operation buffer A as shown in FIG. 6B. In memory addresses 11 to13, the dif f erence is givenby "333"- "333 11=11011, and the difference "0" is stored in a memory address 13 in the operation buffer A.

When the difference between the newly received message which is temporarily stored in the primary buf f er and the received message which is already stored in Memory B is computed, the difference is replaced with substituted value on the basis of a table" A. The substituted value thus obtained is stored in corresponding addresses of Memory C (step 208) In an example shown in FIG. 6B, since the difference "177" in the memory addresses 3 to 5 corresponds to " more than 100" according to the table A, the subs ti tuted value becomes - 5", which is stored in respective corresponding memory addresses 3 to 5 of Memory C. Since the dif f erence 110" in the memory addresses 11 to 13 corresponds to the substituted value "0" according to the table A, the substituted value "0" is stored in the respective corresponding memory addresses 11 to 13 of Memory C. Since the data of the other memory addresses in Memory C are initialized in step 205, all the data in Memory C become '1011 as a result except those stored in the addresses 3 to 5.

When the substituted values are stored in Memory C, thereceived message which is temporarily stored in the primary buffer is overwri tten on the data in Memory B (s tep 2 0 9), and the time - stamp data stored in the Memory B is renewed (step 211 Then, the notification unit 6 notifies the arrival of a new message (step 210), and the received message is displayed on the LCD 8 (step 219) In this case, the received message is displayed in a color corresponding to the substituted value in accordance with the table B. That is to say, a portion of the received message which corresponds to the memory addresses 3 to 5 and stores the data of 112221, is displayed in a red color on the basis of the table B because the substituted value corresponding thereto is 5. The remaining portion of the received message is displayed in a black color similarly to usual cases on the basis of the table B,because the substituted value -corresponding thereto is "0". FIG-7B shows a suitable example of the above descriptions, where a portion which corresponds to the memory addresses 3 to 5 and stores the data of 11222- is displayed in a red color., and the remaining portion is displayed in a black color.

Notification of the arrival of the new message and display of the received message in steps 210 and 219 are stopped when a predetermined time, 20 sec for instance, has passed or the user operates the reset switch 12.

When a newly-received message which is temporarily stored in the primary buffer is compared with the received message which is already stored in Memory B and it is judged that both messages coincide with each other in step 207, for example, when the new message 11 a u (105) 9 9 (333) 11 is again received when the received message 11 a u (105) 9 9 (333) 11 is already stored in Memory B, the newly received message which is temporarily stored in the primary buffer is overwritten into Memory B, and the time- stamp data stored in Memory B is renewed. Since the received message is the same as the formerly received message, notification by means of the notification unit 6 and display on the LCD 8 are not conducted, and the state of standby is recovered. In this case, the user may previously set the paging receiver so that the arrival of a new message is notified by the notification unit 6 and the received message is displayed on the LCD 8. FIG. 7A shows a suitable example of display of the newly-received message when the newlyreceived message is the same as the f ormerly- received message.

In FIG.8, when the power-supply is turned on, in other words, the paging receiver is standing-by ready to receive a new message, it is judged whether an operation for reading the messages of the individual ID or the information ID is conducted by the user or not (steps 302). For example, the user presses the selective switch 13 to select the ID which he desires to read from the individual ID or the information ID. If the read switch 11 is pressed in condition that desired ID is selected, the message of the desired ID is displayed. When the user has conducted an operation for reading the messages of the individual ID (YES in step 302), the received messages stored in Memory A are displayed on the LCD 8 (step 305). In this case, whenever the user presses the read button 11, the formerly received messages are successively displayed.

On the other hand, when an operation for reading the messages of the information ID is conducted (NO in step 302, the received messages which are stored in Memory B are successively displayed on the LCD 8. In this case, whenever the user presses the read button 11, the received message is successively displayed in the order of ID1, ID2 and ID3. Moreover, the specified portions of the received message are displayed in colors dif f erent f rom those of other portions on the basis of the substituted values stored in Memory C (step 303) Display of the received message is stopped when a predetermined time, 20 sec for instance, has passed or the user operates the reset switch 12.

As mentioned in the above, according to this embodiment, since the newly received message is compared with the formerly received message and a color used for display is changed in accordance with a difference therebetween, the user can exactly recognize the di f f erence in the newly-received message and the f ormerly-received message.

Next, a wireless receiving apparatus, or desirably a paging receiver, according to the second preferred embodiment of the invention will be explained, referring to appended drawings.

FIG. 9 shows ablock diagramof an example of thepaging receiver according to this embodiment.

in Figs.9 and 3, the structural elements having the same functions are denoted by the same reference numerals, and detailed explanations thereon will be omitted. In this embodiment, CPU 22 and RAM 23 are provided instead of CPU 4 and RAM 9 shown in FIG - 3.

RAM 23 is provided with not only Memories A, B and C, a primary buffer, an operation buffer A and tables A and B, those being respectively provided for RAM 9 shown in FIG.3, but also a table C which determines colors to be used for displaying the message in accordance with a difference between a time of the arrival of a newly-received message and another time when a message stored in a memory is read, in other words a passage of the time since the time of the arrival of the message, as well as the substituted value stored therein.

FIC.10 shows an example of an internal table of RAM 23 shown in FIG. 9.

In FIG.10, since the functions of Memories A,B, and C, the primary buffer, the ope ration buffer A and tables A and B are the same as those shown in FIGA, detailed explanations thereon will be omitted. The table C stores information as to the colors to be used f or displaying the message, which is determined in accordance with the passage of time from the arrival of the message till the message- reading as well as the substituted value stored therein. For example, when the message concerned with the substituted value of 11511 is read, if the message is read before 5 hours has passed since the arrival of the message, a por tion of the message contained in memory addresses corresponding to the substituted value of "5" is displayed in a red color. on the other hand, in case that the message is read after 5 hours has passed since the arrival of the message, the aforementioned portion is displayed in a black color.

Ne xt, an example of an operation of the paging receiver at the time when the message is read will be explained referring to FIGs.11 and 12.

In FIG. 11, in a state that the power- supply is turned on, in other words, in a state of standby, it is judged whether an operation for reading the message of the individual ID or the information ID is conducted by the user or not (step 502) - Since the process in the step 502, and that in the step 505 when an operation for reading the individual ID is conducted by the user are respectively the same as the processes in steps 302 and 305 shown in FIG. 8, the detailed explanation thereon will be omitted.

In the process in step 502, when an operation for reading the message of the information ID is conducted by the user, a dif f erence between the time- stamp data stored in Memory B and the present time counted by the clock 21, that is to say, the passage of time G, is computed (step 507). Then, a color to be used for displaying themes sage is determined in accordance with the substituted values stored in Memory C for the assigned ID and the passage of time G derived by the computation. As a result, the message is displayed in a color which is determined in accordance with the passage of time since the arrival of the message as well as the difference between the newly received message and the formerly received message (step 503) Display of the received message is stopped when a predetermined time has passed or the user operates the reset switch 12.

FIG. 12 shows a state of display of the LCD 8 in an example shown in FIGs. 6A and 6B. That is to say, themessage "a a (222) S 9 (333) 11 was newlyreceived when the received message 'Icy a (105) S S (333) 11 had been already stored in Memory B, and after a while, the message is read by the user. in the example shown in FIG. 12, the message is read when 2 hours has passed since the arrival of the message, and 0222- is displayed in a red color on the basis of table C.

As mentioned in the above, according to this embodiment, since the color to be used for displaying the message is determined in accordance with the passage of the time since the arrival of the message as well as the dif f erence between the newly received message and the formerly received message, the user can precisely know freshness of the newly received message, the difference between the newly received message and the formerly received message, and the time of renewal of the message through the color used for displaying the message.

The wireless communication apparatus according to the invention is never restricted to the above mentioned embodiments. For example, although the color used for displaying a specified portion of the message is changed in accordance with the dif f erence between the newly received message and the formerly received message and the passage of time since the arrival of the newly received message in the aforementioned invention, the aforementioned specified portion may be expressed by emphatic characters or covered with non-meshing half-tone instead of changing the color usedof display. A brightness of the specified portion may be switched on and off.

The wireless communication apparatus according to the invention may be so constructed that the data stored in RAM 9 or 23, such as color used for character display, a threshold value of the difference in the message or that of the passage of time may be selected by the user or the operator.

Although explanations are given on an example of the paging receiver, the invention can be applied to wireless communication apparatuses of all kinds which can be supplied with information services, such as a portable telephone set or a personal handy-phone system (PHS).

According to the wireless communication apparatus according to the invention, since the newly received message is compared with the formerly received message and a color used for displaying the _19newly-received message is changed in accordance with the difference between the two aforementioned messages, the user can precisely know the difference between the newly-received message and the f ormerly- received message through a colour used for displaying the 5 message.

Moreover, since a colour used for displaying the message can be changed in accordance with the passage of time since the arrival of the message, the user can also precisely recognize freshness of the message and the time of renewal of the message.

Although the invention has been described with respect to specific embodiments for complete and clear disclosure, the appended claims are not to be thus limited but are to be construed as embodying all modifications and alternative constructions that may occur to one skilled in the art and which fairly fall within the basic teaching herein set forth.

Each feature disclosed in this specification (which term includes the claims) and/or shown in the drawings may be incorporated in the invention independently of other disclosed and/or illustrated features.

The text of the abstract filed herewith is repeated here as part of the specification.
