Description

[0001]
TECHNICAL FIELD OF THE INVENTION
The present invention relates to an e-mail creation device, and more particularly, to an e-mail creation device that creates an e-mail address based on a telephone number.
[0002]
[Prior art]
2. Description of the Related Art In recent years, with the development of communication networks, electronic mail (e-mail) has been actively used. Recently, communication devices other than personal computers (PCs), such as personal digital assistants (PDAs), have been used. Assistant, a mobile phone, and a PHS (Personal Handyphone System). E-mail can be transmitted and received between different types of communication devices such as PCs, PDAs, mobile phones, and PHSs via a communication network. For example, transmission and reception of e-mails between a PC and a mobile phone are possible. It is possible.
[0003]
Conventionally, in order to send an e-mail, a user has to input a destination e-mail address (e-mail destination), or find and select a destination e-mail address from a registration means such as an address book. In each case, the user had to know the e-mail address of the destination. In other words, the e-mail could not be sent without knowing the e-mail address of the other party.
[0004]
Further, even if the user knows the e-mail address of the other party, if the user is not registered in the address book, the user must input the e-mail address of the other party. An example of an e-mail address is shown below.
tarou_yamada @ fedcba. co. jp
As described above, the e-mail address is composed of a user name "tarou_yamada" for identifying each individual, a delimiter "@", and a domain name "fedcba.co.jp". The domain name is composed of an organization name “fedba”, an attribute “co”, and a region name “jp”, and this domain name differs depending on the managing organization.
[0005]
As a technique for solving the above-described problem, in Patent Document 1 below, a telephone number of a mobile phone and an e-mail address are stored in association with each other, and a user inputs a telephone number of a transmission destination. A technology for automatically creating a destination e-mail address is disclosed.
[0006]
FIG. 11 shows a block diagram of an electronic mail address creation system described in Patent Document 1. The e-mail address creation system includes an input unit 1 for inputting a telephone number, a telephone number memory unit 2 for storing a telephone number input from the input unit 1, and a telephone number stored in the telephone number memory unit 2. Of the numbers (at this moment, the telephone number of the mobile phone is composed of 11 digits), an extracting unit 3 for extracting the upper n digits, and an extracting memory unit 4 for storing the data extracted by the extracting unit 3 A storage unit 6 in which a telephone number set for each carrier and address data after a delimiter "@" for creating an e-mail address for the carrier are stored in association with each other. It comprises a unit 7 and a display unit 8.
[0007]
The collation unit 5 collates the extracted data stored in the extraction memory unit 4 with data of a specific part of the data stored in the storage unit 6, and detects matching data in the storage unit 6 as a result of the collation. If it can, the address data after "@" stored corresponding to the detected telephone number is output to the synthesizing section 7.
[0008]
The synthesizing unit 7 synthesizes the address data after “@” output from the collating unit 5 and the telephone number stored in the telephone number memory unit 2 and is stored in the telephone number memory unit 2. After the telephone number, the address data after "@" output from the collating unit 5 is joined to create a final e-mail address, which is output to the display unit 8.
[0009]
FIG. 12 is a flowchart showing a processing procedure performed by the electronic mail address creation system described in Patent Document 1. In this e-mail address creation system, when a telephone number is input (step S1), the first n digits of the input telephone number (because the number of digits at the beginning is one less than 11 digits of the telephone number, n = 10) is extracted (step S2), the upper n digits of the extracted telephone number are collated with the data stored in the storage unit 6 in advance, and whether or not there is compatible telephone number data is determined. Is determined (step S3).
[0010]
If there is a matching telephone number, the address data after "@" stored in association with the matching phone number data is extracted (step S5), and then the extracted address data after "@" is stored in step S1. An e-mail address is created by adding it to the telephone number entered in step (step S6).
[0011]
On the other hand, if there is no compatible telephone number, the number of n digits is reduced by one digit (step S4), the process returns to step S2, and then the upper n digits of the input telephone number (the second time, n = 9, ) Is extracted (step S2), the upper n digits of the extracted telephone number are collated again with the data stored in the storage unit 6, and it is determined whether or not there is compatible telephone number data (step S2). Step S3). If there is no suitable telephone number, the processing of steps S2 to S4 is repeated, and when n finally becomes 0, the processing ends as "there is no corresponding data".
[0012]
An e-mail address can be created by the e-mail address creation system described in Patent Document 1 because an e-mail address "ghi-jkab-lmrs @ HIJ" corresponding to a mobile phone whose telephone number is "ghi-jkab-lmrs". .KL.MN ”is the telephone number“ ghi-jkab-lmrs ”.
[0013]

[0014]
[Problems to be solved by the invention]
An e-mail address initially assigned to a mobile communication device such as a mobile phone or a PHS is, for example, “090770XXXXXX@docomo.ne.jp”. That is, the user name of the e-mail address is the respective telephone number "090770XXXXXX".
[0015]
However, recently, if the user name is a telephone number, there is a high possibility that so-called unsolicited e-mail such as e-mail for solicitation etc. will be sent. The number of cases where it is changed to a character string is increasing.
[0016]
Changing the user name from a phone number to another string is very effective as a spam countermeasure, but on the other hand, it seems that the use of e-mail is severely restricted. For example, if the user name is a telephone number, the number of character strings is unified to 11 characters, and the type of character string is also unified to numbers, which makes e-mail address management very easy. In addition, it is thought that the effect will be greatly exerted when an administrative organization such as the police sends a formal e-mail (for example, an e-mail for notifying a disaster or the like) to many destinations instead of a junk e-mail.
[0017]
Therefore, at this time, the user name is changed from the phone number to another character string as a countermeasure for spam, but in the future, if the spam is resolved by another countermeasure, the phone number will be changed to the user name as it is It is thought that it will be used as.
[0018]
By the way, users of mobile communication devices such as mobile phones are increasing year by year. Until recently, all mobile phone numbers started with “090”, but recently there are also those that start with “080”. ing.
As described above, when a telephone number having a different upper digit is added, as in the invention described in Patent Document 1, the upper n digits of the extracted telephone number and the data stored in the storage unit 6 in advance are stored. When matching is performed, there are many cases where a matching telephone number is not detected. Further, according to the invention described in Patent Literature 1, when a suitable telephone number is not detected, steps S2 to S4 shown in FIG. 12 are repeated about ten times (until n becomes 10 to 0). , Very inefficient.
[0019]
On the other hand, even if a suitable telephone number is detected, as described above, at this time, the user name of the e-mail address is often changed to another character string. Even if an e-mail address is created by adding subsequent address data and an e-mail is sent using the e-mail address, it is expected that the e-mail will not reach the other party in many cases.
[0020]
In this way, if the user selects the address data following the telephone number from the mobile telephone number, creates an e-mail address, and attempts to send the e-mail, the result desired by the user may not be obtained. Therefore, the efficiency of these processes is very important.
[0021]
For example, even if a matching telephone number is not detected, if the time from the start of the verification to the obtaining of the result is only a short time, the user will hardly be dissatisfied. Even if the e-mail does not reach the other party with the created e-mail address, if the time required to create the e-mail address is a short time, the user's dissatisfaction may be small.
[0022]
The present invention has been made in view of the above problems, and provides an e-mail creating apparatus capable of efficiently creating an e-mail address from a telephone number of a mobile communication device such as a mobile phone or a PHS. It is an object.
[0023]
Means for Solving the Problems and Their Effects
FIG. 1 is a diagram showing an example of the relationship between the first six digits of the telephone number of a mobile phone (currently 11 digits) and the carrier to which the mobile phone to which the telephone number is assigned belongs, and the first six digits of the telephone number Are "090900" and "090901" belong to the same N company, and the first six digits are "090910" and "090911". The first six digits are "090920" and "090921". Indicate that the mobile phones belonging to the same company T belong to the same company T, and the mobile phones having the first six digits “090930” and “090931” belong to the same company K.
[0024]
As described above, the telephone number of the mobile phone cannot be freely set by each company, but a number that can be set for each company is assigned to the first six digits. In other words, the company to which the mobile phone belongs can be determined from the first six digits assigned to each company. At this time, the first digit and the third digit are unified with "0", so it is necessary to determine the company to which the mobile phone belongs using only the second digit and the third to sixth digits in total. Can be. The domain name of the e-mail address of the mobile phone is unified for each company. For example, the domain name of company N is “docomo.ne.jp”, and the domain name of company K is “ezweb.ne.jp”. jp ", and the domain name of company J is" jp-k.ne.jp ".
[0025]
An electronic mail creation device (1) according to the present invention associates a designating means for designating a telephone number of a mobile communication device such as a mobile phone with a code indicating a carrier of the mobile communication device, and specifies at least the carrier. Extraction for extracting a part corresponding to a telephone number part stored in the first storage means from a first storage means storing a necessary telephone number part and a telephone number designated by the designation means An e-mail creating apparatus comprising: means for comparing the part extracted by the extracting means with a telephone number part stored in the first storage means, wherein the comparing means If it is determined that the part that matches the part extracted by the extracting means is not stored in the first storage means, the transfer to which the telephone number specified by the specifying means is assigned is performed. A determination unit that determines that the body communication device does not belong to any carrier; and a telephone number portion stored in the first storage unit includes a telephone number that is unnecessary for specifying the carrier. Is not included.
[0026]
The part extracted by the extracting means is a part corresponding to the telephone number part stored in the first storage means (a part necessary for specifying a carrier). In other words, the part extracted by the extracting means includes at least a part necessary for specifying the carrier (for example, the first six digits of the telephone number).
[0027]
Therefore, if the part extracted by the extracting means is compared with the telephone number part stored in the first storage means, the mobile communication device to which the telephone number specified by the specifying means is assigned The belonging carrier can be determined (however, data matching the portion extracted by the extraction means needs to be stored in the first storage means).
[0028]
According to the electronic mail creation device (1), at least the carrier is specified in association with a code indicating a carrier of the mobile communication device (for example, a code indicating N company, K company, J company, T company, etc.). The first storage means in which a necessary telephone number portion (for example, the first six digits of the telephone number) is stored, and the telephone number designated by the designation means, are stored in the first storage means. The extracting means for extracting a part corresponding to the telephone number part (for example, the first six digits of the telephone number); a part extracted by the extracting means; a telephone number part stored in the first storage means; And a matching unit that matches the part extracted by the extracting unit. If data matching the portion extracted by the extracting unit is stored in the first storage unit, Number It is possible to determine the carrier belongs mobile communication devices temple.
[0029]
Also, as described above, the domain name of the e-mail address of a mobile communication device such as a mobile phone is set for each carrier, so if the carrier can be determined, the domain name is initially assigned to the mobile communication device. E-mail address provided. Therefore, even if you do not know the e-mail address of the other party, you can send an e-mail if you know only the telephone number.
[0030]
Also, according to the electronic mail creation device (1), when the matching unit determines that the one that matches the part extracted by the extraction unit is not stored in the first storage unit, The apparatus further includes the determination unit that determines that it is not possible to determine which carrier the mobile communication device assigned to the telephone number specified by the specification unit belongs to.
[0031]
As described above, when the data that matches the portion extracted by the extraction unit is stored in the first storage unit, the mobile communication device to which the telephone number designated by the designation unit is assigned Can be determined, but if data matching the extracted part is not stored in the first storage means, the telephone number specified by the specification means is assigned. The carrier to which the mobile communication device belongs cannot be determined.
In other words, if data corresponding to the extracted part is not stored in the first storage means, the mobile communication device to which the telephone number designated by the designation means is assigned is determined by which carrier. Cannot be determined, and the e-mail address cannot be obtained from the telephone number.
[0032]
Therefore, according to the electronic mail creation device (1), the designating means can be performed without repeating the processing of steps S2 to S4 (see FIG. 12) about ten times as in the invention disclosed in Patent Document 1. Is determined that it is not possible to determine to which carrier the mobile communication device assigned to the telephone number specified by (1) belongs (i.e., that the e-mail address cannot be created from the telephone number). Can be performed efficiently.
[0033]
Further, according to the electronic mail creating device (1), the telephone number portion stored in the first storage means has the last m digits (for example, the last 5 digits) of the telephone number that is unnecessary for specifying the carrier. For example, if m is 5, the telephone number portion stored in the first storage means is a maximum of 6 digits (a minimum of 2 digits and a total of 4 digits of 3 to 6 digits). ).
[0034]
Therefore, unlike the invention disclosed in Patent Literature 1, the first 10 digits of the telephone number are not compared with the first 10 digits of the telephone number, but only the first 6 digits of the telephone number. The carrier to which the mobile communication device to which the telephone number specified by the specifying means is assigned can be obtained.
[0035]
Further, the electronic mail creation device (2) according to the present invention, in the electronic mail creation device (1), stores a domain name set for each carrier in association with a code indicating a carrier. Means corresponding to the mobile communication device from the second storage means based on the carrier of the mobile communication device to which the telephone number designated by the designation means has been determined by the matching by the matching means. Reading means for reading a domain name of an e-mail address to be read, and an e-mail address corresponding to the mobile communication device from a telephone number specified by the specifying means and a domain name read by the second reading means. And a creating means for creating the information.
[0036]
According to the electronic mail creation device (2), an electronic mail address corresponding to the mobile communication device is stored in the second storage device based on the carrier of the mobile communication device determined by the verification by the verification device. Is read, and an e-mail address corresponding to the mobile communication device is created from the telephone number specified by the specifying means and the read domain name.
[0037]
Therefore, even if you do not know the e-mail address of the other party, you can send an e-mail if you know only the telephone number. Even if the e-mail address is not registered in the registration means such as the address book, the e-mail address is automatically created if only the telephone number is specified, so that the trouble of inputting by the user can be saved.
[0038]
Further, the electronic mail creation device (3) according to the present invention is configured such that, in the electronic mail creation device (1) or (2), the electronic mail creation device (3) moves via the communication means to the first information providing device installed outside. First requesting means for requesting transmission of information in which a code indicating a carrier of the body communication device is associated with at least a telephone number part necessary for specifying the carrier; and providing the first information based on the request. First receiving means for receiving information transmitted from the device, and a first means for updating data stored in the first storage means based on the information received by the first receiving means. Updating means.
[0039]
As described in the item of "Problems to be Solved by the Invention", the number of users of mobile communication devices such as mobile phones is increasing year by year, and until recently, all mobile phone numbers started with "090". However, recently, there are some which start with “080”. As described above, when a telephone number having a different upper digit is added, it is often difficult to determine the carrier to which the mobile communication device belongs, and it is difficult to create an e-mail address from the telephone number.
[0040]
According to the electronic mail creating device (3), a code indicating a carrier of the mobile communication device is provided to the first information providing device (for example, a server connected to the Internet) via the communication means. Requesting transmission of information in which at least a telephone number part necessary for specifying the carrier is associated, and based on the request, based on the information transmitted from the first information providing apparatus, the first The data stored in the storage means can be updated. Therefore, even if a new telephone number is added or the telephone number is changed, an e-mail address can be created from the telephone number appropriately.
[0041]
In the electronic mail creation device (4) according to the present invention, in the electronic mail creation device (3), the determination unit may determine which carrier the mobile communication device to which the telephone number extracted by the designation unit is assigned. If it is determined that it is not possible to determine whether the request belongs to the first information providing apparatus, the first requesting means makes the request to the first information providing apparatus.
[0042]
According to the electronic mail creation device (4), the determination unit determines that the carrier to which the mobile communication device assigned the telephone number extracted by the designation unit belongs cannot be determined. (That is, when it is determined that a part that matches the part extracted by the extraction unit is not stored in the first storage unit), the request is sent to the first information providing apparatus. Will be
[0043]
Therefore, if the part that matches the part extracted by the extraction means is not stored in the storage means (that is, if there is a high possibility that a new telephone number has been added or a telephone number has been changed, etc.) ), The request is made to the first information providing apparatus, and the first storage means is updated. This makes it possible to automatically update the first storage means at an appropriate timing.
[0044]
Further, the e-mail creation device (5) according to the present invention is set for each carrier in any one of the e-mail creation devices (1) to (4) in association with a code indicating a carrier. The third storage unit in which an e-mail display condition is stored, and the third storage unit determined based on the collation by the collation unit, based on the carrier of the mobile communication device to which the telephone number designated by the designation unit is assigned. A calculating means for obtaining an e-mail display condition corresponding to the mobile communication device from the storage means of No. 3, and a setting means for setting an e-mail creation environment based on the e-mail display condition obtained by the calculating means. It is characterized by having.
[0045]
By the way, as described in the item of “Prior Art”, electronic mail can be transmitted and received between different types of communication devices such as PC, PDA, mobile phone, and PHS via a communication network. When e-mail is transmitted and received between different communication devices, some problems arise due to differences in functions of the communication devices.
[0046]
In particular, mobile phones and PHS have a greater restriction on e-mail display conditions (eg, the number of characters that can be received) than PCs and PDAs. In some cases, the e-mail message may not be properly displayed on the recipient mobile communication device due to the difference between the number of transmittable characters and the number of receivable characters.
[0047]
For example, when a message of up to 250 characters is transmitted to a mobile communication device having 250 characters in one electronic mail, the entire message can be displayed on the mobile communication device. If a message exceeding 250 characters is transmitted, the entire message cannot be displayed on the mobile communication device.
[0048]
According to the electronic mail creation device (5), an electronic mail display corresponding to the mobile communication device is stored in the third storage unit based on the carrier of the mobile communication device determined by the verification by the verification unit. Conditions are determined, and an e-mail creation environment for e-mail to be transmitted to the mobile communication device is set based on the e-mail display conditions.
[0049]
Thus, it is possible to prevent a situation in which a message exceeding 250 characters is transmitted to a mobile communication device having 250 characters that can be received. The electronic mail display conditions in the mobile communication device include, in addition to the number of receivable characters, for example, the number of display characters per line, the number of display lines, the amount of receivable data, an openable attached file, and the like.
[0050]
Further, the electronic mail creation device (6) according to the present invention is the electronic mail creation device (5), wherein the mobile communication device is connected to a second information providing device installed outside via a communication unit. A second requesting unit for requesting transmission of information in which a code indicating a carrier is associated with an e-mail display condition set for each carrier, and transmitted from the second information providing apparatus based on the request. Second receiving means for receiving incoming information, and second updating means for updating data stored in the third storage means based on the information received by the second receiving means. It is characterized by having.
[0051]
According to the electronic mail creation device (6), a code indicating a carrier of the mobile communication device is transmitted to the second information providing device (for example, a server connected to the Internet) via the communication unit. And the transmission of information in which the electronic mail display conditions set for each carrier are associated with each other. Based on the request, the third information is transmitted based on the information transmitted from the second information providing apparatus. The data stored in the storage means can be updated. Therefore, even if the e-mail display conditions set for each carrier are changed, the e-mail creation environment can be appropriately set.
[0052]
BEST MODE FOR CARRYING OUT THE INVENTION
Hereinafter, an embodiment of an e-mail creation device according to the present invention will be described with reference to the drawings. FIG. 2 is a block diagram schematically showing a main part of an e-mail creation device (mobile phone) according to Embodiment (1).
[0053]
In the figure, reference numeral 11 denotes a mobile phone having functions such as creation, transmission, and reception of e-mail. The mobile phone 11 is a CPU (Central Processing Unit) 12, a ROM (Read Only Memory) 14, and a RAM (Random). The storage unit 13 includes an access memory 15, an input unit 16, a display unit 17, and a communication unit 18. These units are connected by a connection bus 19.
[0054]
The ROM 14 stores a program related to the operation of the mobile phone 11, and the RAM 15 associates a carrier code indicating a carrier of a mobile communication device such as a mobile phone with a telephone number part ( Here, a storage area 15a (see FIG. 3) for storing the first six digits of the telephone number and a storage area 15b (see FIG. 3) for storing the domain name set for each carrier in association with the carrier code. 4), a storage area 15c (see FIG. 5) for storing e-mail display conditions (here, the number of receivable characters) set for each carrier in association with a carrier code, and in association with a name. And a storage area 15d (so-called address book) for storing telephone numbers.
[0055]
FIG. 3 shows an example of data stored in the storage area 15a. Carrier codes "01", "02", "03", and "04" indicate N company, K company, J company, and T company, respectively, and telephone numbers whose first six digits are "090900" and "090901" Indicates that the mobile phone to which N is assigned belongs to Company N, and that the mobile phone to which the phone number whose first six digits are “090960” and “090961” belongs to Company K.
[0056]
FIG. 4 shows an example of data stored in the storage area 15b. The domain name set for the N company is “docomo.ne.jp”, and the domain name set for the K company is “ezweb. ne.jp ", which indicates that the domain name set for the company J is" jp-k.ne.jp ".
[0057]
FIG. 5 shows an example of data stored in the storage area 15c. The number of receivable characters of the mobile phones belonging to N company, K company, J company, and T company is X, respectively. _N , X _K , X _J , X _T Is shown. Note that even the mobile phones belonging to the same company have various numbers of receivable characters such as 6000 characters, 3000 characters, and 200 characters depending on the contract content of each contractor. Therefore, the number of receivable characters stored in the storage area 15c is different. It is desirable to use a standard contract.
[0058]
The communication unit 18 connects the connection bus 19 and a communication line (not shown) to make a call to another communication device, perform transmission / reception of an e-mail with another communication device, and connect to the Internet. It is possible to access the connected server and the like. In addition, as this communication line, a telephone line and the like can be mentioned.
[0059]
Next, the processing operation (1) performed by the CPU 12 in the electronic mail creation device (mobile phone 11) according to Embodiment (1) will be described based on the flowcharts shown in FIGS. First, transmission / edit processing of an e-mail is instructed through the input unit 16, and when a telephone number is input as a destination of the e-mail, the input information is taken in (step S11). The first six digits are extracted (step S12). As for the input of the telephone number through the input unit 16, there are a case where the user inputs numbers one by one and a case where the user selects a telephone number stored in the storage area 15d (address book). is there.
[0060]
Next, the upper six digits of the extracted telephone number are collated with the data stored in the storage area 15a of the RAM 15 (step S13), and telephone number data matching the telephone number input in step S11 is stored. It is determined whether or not it exists in the area 15a (that is, whether or not the one that matches the extracted first six digits of the telephone number is stored in the storage area 15a) (step S14).
[0061]
If it is determined that there is telephone number data that matches the storage area 15a, then a carrier code corresponding to the matching telephone number data is read from the storage area 15a (step S15), and the storage area is determined based on the read carrier code. The domain name corresponding to the carrier code is read from 15b (step S16).
[0062]
Thereafter, an e-mail address of the mobile communication device to which the telephone number is assigned is created from the telephone number captured in step S11 and the domain name read in step S16 (step S17). Specifically, an e-mail address is created by adding a domain name after the telephone number via a delimiter "@".
[0063]
Next, based on the carrier code read in step S15, an e-mail display condition corresponding to the carrier code is read from the storage area 15c (step S18), and based on the read e-mail display condition (here, the number of receivable characters). Then, an e-mail creation environment is set (step S19, see FIG. 7).
[0064]
On the other hand, if it is determined in step S14 that there is no telephone number data that fits in the storage area 15a, a message such as "Automatic creation of a mail address is not possible" is displayed on the display unit 17, and the e-mail address is converted The user is notified that it cannot be created (step S20), and then the electronic mail address is set to a state where the user can input the e-mail address, and the user waits for the input of the e-mail address through the input unit 16 (step S21).
[0065]
When an e-mail address is input, the input information is fetched (step S22). Next, a domain name is extracted from the input e-mail address (step S23), and based on the extracted domain name, the storage area 15b is stored. Is read from (step S24), and thereafter, the process proceeds to step S18.
[0066]
In step S19 (setting of e-mail creation environment: see FIG. 7), first, the number of receivable characters is set to C based on the e-mail display conditions read out in step S18. _max (Step S31), and then the mode shifts to a message input / edit mode for inputting / editing a message (step S32). After that, the number of characters currently input becomes the number of receivable characters C _max Is determined (step S33).
[0067]
The number of characters that can be received is the number of characters that can be received C _max If the number of characters exceeds the number of characters that can be received corresponding to the mobile communication device to which the e-mail is to be sent, a warning message such as “exceeding the number of characters” is displayed on the display unit 17. Is notified to the user (step S34), and thereafter, the process proceeds to step S35. On the other hand, the number of input characters is the number of receivable characters C _max If it is determined that the value does not exceed the threshold value, no warning message needs to be displayed, and the process skips step S34 and proceeds directly to step S35.
[0068]
In step S35, it is determined whether or not the end of the message input / edit is instructed by the user through the input unit 16. If it is determined that the end of the message input / edit is instructed, the processing operation (1) is ended. On the other hand, if it is determined that the end of the message input / edit has not been instructed, the process returns to step S32.
[0069]
According to the e-mail creation device (mobile phone 11) according to the above-described embodiment (1), an e-mail can be transmitted as long as the telephone number is known without knowing the e-mail address of the other party. Even if the e-mail address has not been registered in the storage area 15d serving as the address book in association with the name, the e-mail address is automatically created by specifying the telephone number. You can save time and effort.
[0070]
Also, whether or not an e-mail address can be created from the telephone number is determined based on a determination result as to whether or not the extracted telephone number that matches the first six digits is stored in the storage area 15a. . Therefore, unlike the invention disclosed in Patent Document 1, the above-described determination can be performed without repeating the processing of steps S2 to S4 (see FIG. 12) about ten times. Can be faster.
[0071]
Further, the telephone number portion stored in the storage area 15a does not include the last five digits of the telephone number that is unnecessary for specifying the carrier. Therefore, unlike the invention disclosed in Patent Literature 1, the first six digits of the telephone number are not collated but the first six digits of the telephone number are collated. The carrier to which the mobile communication device to which the telephone number is assigned belongs can be obtained.
[0072]
Also, based on the carrier of the mobile communication device, an e-mail display condition (here, the number of receivable characters) corresponding to the mobile communication device is read from the storage area 15c, and based on the e-mail display condition. An e-mail creation environment for e-mail to be transmitted to the mobile communication device is set.
[0073]
Thus, it is possible to prevent a situation in which a message exceeding 250 characters is transmitted to a mobile communication device having 250 characters. The electronic mail display conditions in the mobile communication device include, in addition to the number of receivable characters, for example, the number of display characters per line, the number of display lines, the amount of receivable data, an openable attached file, and the like.
[0074]
By the way, an electronic mail transmitted from a certain communication device is delivered to a communication device as a transmission destination via a DNS (Domain Name System) server. The DNS server plays a role of transmitting an e-mail to another appropriate DNS server in accordance with the domain name included in the e-mail address specified by the communication device that is the transmission source.
[0075]
As described above, the domain name is indispensable for transmission and reception of e-mail, but the domain name is not necessary until the above-described processing is performed by the DNS server. In other words, as a destination of the e-mail, a character string that does not include a domain name (for example, “090932 ****”) or a character string to which a domain name that does not actually exist (for example, “ Even if the user designates "090932******@eeee.ee.ee"), the e-mail will reach the DNS server.
[0076]
Therefore, in the e-mail creating apparatus according to the above-described embodiment (1), the case where the e-mail creating apparatus is employed in a mobile phone is described. In another embodiment, a PC that sends an e-mail is used. It may be adopted as an information processing device installed between a communication device such as a personal computer, a PDA, a mobile phone, and a PHS, and a DNS server.
[0077]
FIG. 8 is a block diagram schematically showing a main part of an information processing system including an electronic mail creation device (mobile phone) according to Embodiment (2). In the figure, reference numeral 11A denotes a mobile phone, and the mobile phone 11A can access a server 24 connected to the Internet 23 via the base station 22 and the Internet 23. The electronic mail creation device (mobile phone 11A) according to the embodiment (2) has the same configuration as the mobile phone 11 shown in FIG. Reference numerals are used, and descriptions of other components are omitted.
[0078]
The server 24 includes a CPU 25, a storage unit 26 having a ROM 27 and a RAM 28, and a communication unit 29 for exchanging information with the outside via the Internet 23. These units are connected by a connection bus 30. ing.
The ROM 27 stores a program related to the operation of the server 24, and the RAM 28 is associated with a carrier code indicating a carrier of a mobile communication device such as a mobile phone, and a telephone number portion (here, Then, the storage area 28a (see FIG. 3) for storing the first six digits of the telephone number and the e-mail display conditions (here, the number of receivable characters) set for each carrier in association with the carrier code are stored. It is configured to include a storage area 28b (see FIG. 5) for storing. The data stored in the storage areas 28a and 28b are the latest data.
[0079]
When the CPU 25 of the server 24 receives a data update request from an external communication terminal device (for example, the mobile phone 11A) via the Internet 23, the data stored in the storage area 28a of the RAM 28 or the storage area 28b Can be transmitted to the request source.
[0080]
Next, the processing operation (2) performed by the CPU 12A in the electronic mail creation device (mobile phone 11A) according to the embodiment (2) will be described based on the flowcharts shown in FIGS. First, transmission / edit processing of an e-mail is instructed through the input unit 16, and when a telephone number is input as a destination of the e-mail, the input information is fetched (step S41). The first six digits are extracted (step S42).
[0081]
Next, the upper six digits of the extracted telephone number are compared with the data stored in the storage area 15a of the RAM 15 (step S43), and the telephone number data matching the telephone number input in step S41 is stored. It is determined whether or not it exists in the area 15a (that is, whether or not the one that matches the first six digits of the extracted telephone number is stored in the storage area 15a) (step S44).
[0082]
If it is determined that there is telephone number data that matches the storage area 15a, then a carrier code corresponding to the matching telephone number data is read from the storage area 15a (step S45), and the storage area is determined based on the read carrier code. The domain name corresponding to the carrier code is read from 15b (step S46).
[0083]
Thereafter, an e-mail address of the mobile communication device to which the telephone number is assigned is created from the telephone number captured in step S41 and the domain name read in step S46 (step S47). Specifically, an e-mail address is created by adding a domain name after a telephone number via a delimiter "@".
[0084]
Next, based on the carrier code read in step S45, an e-mail display condition corresponding to the carrier code is read from the storage area 15c (step S48), and based on the read e-mail display condition (here, the number of receivable characters). Then, an e-mail creation environment is set (step S49, see FIG. 7).
[0085]
On the other hand, if it is determined in step S44 that there is no telephone number data that matches the storage area 15a, the process proceeds to step S51 (FIG. 10) to display a message such as "need to update data" on the display unit 17. Thus, the user is notified that the data stored in the storage area 15a of the RAM 15 needs to be updated, and then a data update request selection screen (not shown) is displayed on the display unit 17 (step S52).
[0086]
Next, by operating the input unit 16, it is determined whether a data update request is selected by the user through the data update request selection screen (step S53), and it is determined that the data update request is selected. Then, the communication unit 18 is used to access the server 24 and request the server 24 to transmit the latest data in which the carrier code is associated with the telephone number portion necessary for specifying the carrier (step S1). S54).
[0087]
Next, when the information transmitted from the server 24 is received based on the request, the data stored in the storage area 15a is updated based on the received information (Step S55), and thereafter, Step S42 is performed. The upper six digits of the telephone number extracted in step (1) are compared with the data stored in the storage area 15a (that is, the data updated to the latest data) (step S56), and the telephone number input in step S41 is compared. It is determined whether or not the telephone number data conforming to the above exists in the storage area 15a (that is, whether or not the one that matches the extracted first six digits of the telephone number is stored in the storage area 15a) (step S57). ).
[0088]
If it is determined that there is telephone number data suitable for the storage area 15a, the process proceeds to step S45 (FIG. 9) to perform processing for creating an e-mail address. On the other hand, if it is determined that there is no telephone number data that matches the storage area 15a despite the data being updated, a message such as "Automatic creation of an e-mail address is not possible" is displayed on the display unit 17 to display the telephone number. Is notified to the user that the e-mail address cannot be created (step S58), and then the state is set so that the e-mail address can be input, and the user waits for the input of the e-mail address through the input unit 16 (step S58). Step S59).
[0089]
When an e-mail address is input, the input information is fetched (step S60), a domain name is extracted from the input e-mail address (step S61), and based on the extracted domain name, the storage area 15b is stored. Is read from (step S62), and then the process proceeds to step S48 (FIG. 9).
[0090]
On the other hand, if it is determined in step S53 that the data update request has not been selected by the user, the flow advances to step S59 to set a state in which an e-mail address can be input. Wait for is entered.
[0091]
According to the e-mail creating device (mobile phone 11A) according to the above-described embodiment (2), the carrier code and the telephone number required for specifying the carrier are transmitted from the server 24 connected to the Internet 23. The data stored in the storage area 15a of the RAM 15 is updated based on the information in which the parts are associated with each other. Therefore, even if a new telephone number is added or the telephone number is changed, the e-mail address can be created appropriately.
[0092]
In the electronic mail creation apparatus according to the embodiment (2), a request for transmitting the information to the server 24 is made when the user selects it. The creation device may automatically request transmission of the information without receiving a user's selection instruction.
[0093]
Further, the e-mail creating apparatus according to the above-described embodiment (2) requests the server 24 to transmit information in which a carrier code is associated with a telephone number portion necessary for specifying a carrier.
