Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a mobile phone having a call mode for performing a call as a communication mode and a data mode for performing data communication, and a mobile communication network accommodating the mobile phone.
[0002]
[Prior art]
In the mobile data communication field, a system for connecting an external processing device to a mobile phone and performing data communication such as transmission / reception of electronic mail via the mobile phone has been put into practical use. Examples of the external processing device include notebook type and book type computers, and PDAs (Personal Digital (Data) Assistants) such as electronic notebooks. In this type of system, the mobile phone is controlled by an external processing device and functions as a simple communication path.
[0003]
In addition, a communication terminal having a mobile phone function mounted on a PDA has been developed. This type of communication terminal normally has a mode for performing a call and a mode for performing data communication as operation modes, and the user of the communication terminal selects the operation mode as necessary. Use properly.
[0004]
[Problems to be solved by the invention]
By the way, in a system in which an external processing device is connected to a mobile phone, there is a problem in portability because it is necessary to carry the external processing device in addition to the mobile phone. Further, in normal calls, it is normal to use a mobile phone alone, so when performing data communication, the mobile phone must be connected to an external processing device. Although the labor involved in this connection is being simplified, there is no change in the occurrence of some work.
[0005]
On the other hand, the above-mentioned inconvenience does not occur in a communication terminal having a PDA with a mobile phone function. However, PDAs are required to store a large amount of information due to their nature, and thus are larger, heavier and more expensive than cellular phones. On the other hand, if an e-mail transmission / reception service or the like can be realized using only a mobile phone, an inexpensive mobile data communication terminal excellent in portability can be obtained. However, the data communication service is usually a data storage type service, and in order to use the service with sufficiently high quality, it is necessary to mount a large capacity memory in the mobile phone. This invites an increase in manufacturing cost of mobile phones and a decrease in portability.
[0006]
Further, when the number of users of the data communication service increases, an increase in data staying in the mobile communication network is expected. In particular, when a data communication service is used with a mobile phone whose data storage capacity is limited in order to maintain portability, the mobile communication network is compared with the case where the service is used with a computer or PDA as a data processing terminal. There is a possibility that a lot of data stays inside.
[0007]
The present invention has been made in view of the above-described circumstances, can use a call service and a data communication service, and can easily receive a data communication service without providing a large-capacity storage means. At the same time, it is an object of the present invention to provide a mobile phone and a mobile communication network that can suppress an increase in data staying in the network.

[0043]
B: First embodiment
Next, a mobile communication system using the mobile phone according to the first embodiment of the present invention will be described. Note that the hardware configuration of the mobile communication system is the same as the common configuration described above. Accordingly, the same reference numerals are used for the respective parts.
[0044]
B-1: Functional configuration of mobile packet communication network MPN and mobile telephone network MTN
Note that the mobile packet communication network MPN in the first embodiment has a function of transmitting electronic mail (non-connection type data: connectionless type data) to the mobile phone MS by a push method. Specifically, the mobile packet communication network MPN first sends an incoming call request that can be received by the mobile phone MS regardless of the communication mode, asks the mobile phone MS for permission to send an e-mail, and accepts incoming calls. Send the e-mail when prompted. The incoming request includes information indicating the size of the e-mail. Except for the points described above, the mobile packet communication network MPN and the mobile telephone network MTN are the same as described above, and thus further description thereof is omitted.
[0045]
B-2: Functional configuration of mobile phone MS
Next, functions provided in the mobile phone MS will be described with respect to characteristic portions of the present invention. Note that other functions are provided in a general mobile phone and are well known, and thus the description thereof is omitted.
[0046]
FIG. 5 is a block diagram for explaining a functional configuration of the mobile phone MS with respect to a characteristic part of the present invention.
In the control unit 16 shown in this figure, when an incoming call request is supplied from the transmission / reception unit 11, the incoming call reception unit 16a outputs information indicating that the incoming call request has been received to the incoming call notification unit 16q, and an incoming call rejection determination described later. The system waits until an instruction is received from the unit 16h. If the instruction is an incoming call permission instruction, the incoming request is accepted. If the instruction is an incoming call rejection instruction, the incoming request is not accepted. The incoming call reception unit 16a receives an electronic mail supplied from the transmission / reception unit 11 after the reception process, and outputs it to the storage unit 16d described later.
[0047]
The storage unit 16b is for storing electronic mail and has a predetermined storage capacity.
The overwriting possibility determination unit 16c operates when the incoming call reception unit 16a receives an incoming call request. In the email stored in the storage unit 16b, an overwritable (that is, erasable) email and an overwritable email And the determination result is stored in the storage unit 16. d Output to. Here, the determination process is realized by referring to the overwrite permission / inhibition information stored in association with the electronic mail. The determination result output from the overwrite permission / inhibition determination unit 16c includes reception time information corresponding to an overwritable e-mail.
[0048]
The storage unit 16d monitors the usage status of the storage unit 16b, and receives the electronic mail output from the incoming call reception unit 16a. An area based on a preset writing rule and the size of the e-mail is selected from the area on 16b, and the e-mail and its reception time information are written in this area as an e-mail that cannot be overwritten. If another e-mail already exists in the area, the e-mail is overwritten by a new e-mail. Note that the write rule in the present embodiment is basically to write in a free area and to overwrite an overwritable e-mail when the free area is insufficient. However, when overwriting an overwritable e-mail, the oldest reception time is overwritten.
Based on the instruction input from the instruction input unit 14, the overwrite permission / inhibition setting unit 16e changes the content of the corresponding overwrite permission / inhibition information for the email stored in the storage unit 16b.
[0049]
When the incoming request is supplied from the transmission / reception unit 11, the data size detection unit 16f extracts size information of subsequent data included in the incoming request, and uses the size information to send an e-mail following the incoming request. Is detected and the detection result is output to the incoming call rejection determination unit 16h.
The usable capacity detection unit 16g operates when the incoming call reception unit 16a receives an incoming call request, and uses the usage status of the storage unit 16 and the determination result of the overwrite possibility determination unit 16c for the e-mail stored in the storage unit 16. Based on this, the size of an area that can be used for storing new data in the storage unit 16b (hereinafter, usable capacity) is obtained, and the usable capacity is notified to the incoming call rejection determination unit 16h. Specifically, the usable capacity detection unit 16g sets the sum of the free capacity of the storage unit 16b and the capacity occupied by the overwritable e-mail in the storage unit 16b as the usable capacity.
[0050]
The incoming call rejection determination unit 16h compares the data size with the usable capacity, and outputs an incoming call rejection instruction to the incoming call reception unit 16a when the former sufficiently exceeds the latter, and the free space is insufficient. A notification instruction is output to the below-described free space shortage notification unit 16i. The incoming call rejection determination unit 16h outputs an incoming call permission instruction to the incoming call reception unit 16a when the data size does not sufficiently exceed the usable capacity. Note that “the available capacity sufficiently exceeds the data size” means that the available capacity is required to write reception time information, overwrite possibility information, unread / read status information described later, and the like. Means that it is larger than the capacity obtained by adding to the data size.
Upon receiving the insufficient free space notification instruction from the incoming call rejection determination unit 16h, the insufficient free space notification unit 16i displays a message “Insufficient free memory space” on the liquid crystal panel 15a of the liquid crystal display 15. The display control data is output to an image generation unit 16p described later.
[0051]
The call end detection unit 16j monitors information supplied from the transmission / reception unit 11, detects a call end point in the call mode, and outputs a call end notification to an unread notification unit 16m described later.
The read / unread discriminating unit 16k operates when the call end detecting unit 16j detects the end of the call. In the e-mail stored in the storage unit 16b, the unread e-mail that has not been read by the user and the user has already been notified. It discriminate | determines from the read e-mail read, and outputs this discrimination | determination result to the unread notification part 16m. Here, the determination process is realized by referring to the unread / read state information stored in association with the electronic mail. The determination result includes information indicating the number of unread e-mails.
[0052]
When the unread notification unit 16m receives the call end notification from the call end detection unit 16j, the unread notification unit 16m stands by until it receives the determination result from the read / unread determination unit 16k. When the determination result is received, the determination result is indicated by the determination result. Perform processing based on the number of unread emails. Specifically, if the number of unread e-mails is 0, nothing is performed, and if the number of unread e-mails is 1 or more, the message “There are n unread e-mails” (however, the message The display control data for displaying n on the liquid crystal panel 15a is output to the image generation unit 16p described later.
[0053]
The data display unit 16n reads the electronic mail stored in the storage unit 16b in accordance with the instruction input from the instruction input unit 14, and displays display control data for displaying the electronic mail on the liquid crystal panel 15a. If the read e-mail is an unread e-mail, the unread / read state information stored in the storage unit 16b corresponding to the e-mail is rewritten with information indicating the read state.
The image generation unit 16 p generates image data according to the display control data supplied from each unit and supplies the image data to the liquid crystal display 15.
[0054]
When the incoming call notification unit 16q receives the information that the incoming call reception unit 16a has received the incoming call request, the incoming call notification unit 16q generates sound data for causing the sound generation unit 13 to generate a sound that informs the user that an incoming call has been received. 13 is supplied.
[0055]
B-3: Operation of mobile communication system
Next, the operation of the above-described communication system will be described. However, descriptions of operations other than the characteristic operations of the present invention are omitted.
[0056]
(1) Display and overwrite permission information change operation
In FIG. 5, when an instruction to display a desired electronic mail is input from the instruction input unit 14, the data display unit 16n reads an electronic mail corresponding to the instruction from the storage unit 16b, and displays the image generation unit 16p. The contents of the e-mail are displayed on the liquid crystal panel 15a of the liquid crystal display 15, and if the e-mail is an unread e-mail, the unread / read read stored in the storage unit 16b corresponding to the e-mail Rewrite the status information to information indicating the read status.
[0057]
In addition, when data indicating that the desired e-mail overwrite permission information is to be changed is input from the instruction input unit 14, the overwrite permission / non-permission setting unit 16e reads the overwrite permission information corresponding to the e-mail in the storage unit 16b. The overwrite permission / inhibition state is rewritten to be different from the current overwrite permission / inhibition state. Note that a user interface for the user to select a desired e-mail or to refer to the attribute of the e-mail can employ a method similar to that of well-known e-mail management software, and thus description thereof is omitted.
[0058]
(2) Incoming and writing operations
When the incoming call reception unit 16a receives an incoming call request, the sound generation unit 13 generates a sound for notifying the user of the incoming call by the incoming call notification unit 16q. As a result, the user can quickly know that an incoming e-mail has been received. Since the subsequent operation differs depending on the situation, the following description will be given for each case.
[0059]
(1) Operation when the storage unit 16b has sufficient free space
When the incoming call reception unit 16a receives the incoming call request, and the free space in the storage unit 16b is sufficiently large compared to the size of the e-mail that follows the incoming call request, the incoming call reception determination unit 16h receives the incoming call reception unit. An incoming call permission instruction is supplied to 16a. For this reason, the incoming call reception unit 16a performs the incoming call reception process, and the electronic mail and the reception time information are written into a free area of the storage unit 16b by the storage unit 16d. At this time, overwrite enable / disable information indicating that overwrite is not possible and unread / read status information indicating unread are also written in the free space of the storage unit 16b in association with the e-mail.
[0060]
(2) Operation when the storage unit 16b has insufficient free capacity and sufficient usable capacity
When the incoming call acceptance unit 16a receives an incoming call request, if the free space in the storage unit 16b is sufficient and the usable capacity is sufficient compared to the size of the e-mail following the incoming call request, the incoming call rejection determination unit An incoming call permission instruction is supplied from 16h to the incoming call reception unit 16a. For this reason, processing similar to that described above is performed. At this time, the storage unit 16 b The overwritable e-mail already existing in the e-mail and various information corresponding to the e-mail are overwritten and erased in order from the oldest reception time.
[0061]
(3) Operation when the usable capacity of the storage unit 16b is insufficient
When the incoming call acceptance unit 16a receives an incoming call request, if the usable capacity of the storage unit 16b is insufficient compared to the size of the e-mail that follows the incoming call request, the incoming call acceptance unit 16h receives the incoming call reception unit. An incoming call rejection instruction is supplied to 16a. For this reason, the incoming call reception unit 16a does not perform the incoming call reception process.
[0062]
(3) Operation at the end of a call in call mode
When the call in the call mode ends, this is detected by the call end detection unit 16j. At the time of this detection, the number of unread e-mails (here, n) existing in the storage unit 16b is supplied to the unread notification unit 16m by the read / unread discrimination unit 16k. When n is 1 or more, the unread notification unit 16m displays a character string “There are two unread e-mails” on the liquid crystal panel 15a of the liquid crystal display 15 via the image generation unit 16p. On the other hand, when n is 0, the unread notification unit 16m does nothing.
[0063]
B-4: Modification

It is distinguished from read e-mails that have been read. display To the unit 16s. Here, the determination process is realized by referring to the unread / read state information stored in association with the electronic mail. The determination result includes the contents of all unread e-mails.
[0065]
Unread display When receiving the call end notification from the call end detection unit 16j, the unit 16s waits until receiving the determination result from the read / unread determination unit 16r, and when receiving the determination result, the process based on the content of the determination result I do. Specifically, nothing is performed if the content is empty, and display control data for displaying the data on the liquid crystal panel 15a of the liquid crystal display 15 if the data is any data (contents of all unread e-mails). Is output to the image generation unit 16p.
[0066]
(2) Operation
The operation of this modification differs from the operation of the mobile phone MS according to the first embodiment is that when there is an unread e-mail in the storage unit 16b at the end of the call in the call mode, the liquid crystal panel of the liquid crystal display 15 Only the contents of all unread e-mails are displayed in 15a.
[0067]
B-5: Supplement to the first embodiment and modifications
