Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a telephone, and more specifically, to a mobile phone, a PHS terminal, or a fixed telephone having a mail function capable of supporting a plurality of mail types (character transmission types) having different information types.
[0002]
[Prior art]
Currently, most telephones such as mobile phones, PHS terminals, and fixed telephones that are commercially available have a telephone directory function that can register information on a destination (call destination) such as a telephone number or name. In recent years, some of these telephones are equipped with a mail function capable of exchanging text messages, and some models can handle a plurality of mail types.
[0003]
Specifically, a mail type for exchanging short sentences of about 20 characters, a mail type for exchanging long sentences of about 1000 characters, a mail type for exchanging e-mails via the message center, and a text message to a pager. There are types of mail (mail by DTMF signal) and the like. When character transmission is performed using such a mail type, it is necessary that the counterpart terminal also has a mail function of the same mail type.
[0004]
In general, the mail service type that can be used on a telephone is determined by the network operator (carrier) to which it is subscribed. Therefore, when the network operators are between different terminals, or even if the network operators are the same, the mail types that can be handled may differ depending on the model and situation of the telephone, and direct mail exchange cannot be performed. In this case, it is necessary to check the mail types that can be handled by the other party and exchange mails.
[0005]
Furthermore, if a function such as a mail center is available, it is possible to exchange electronic mails between different terminals using the Internet beyond the network operator to which it is subscribed. Also in this case, of course, it is necessary that the other party has a function of exchanging electronic mail.
[0006]
[Problems to be solved by the invention]
In recent telephone sets, particularly mobile communication terminals such as mobile phones and PHS terminals, models having a mail function that can handle a plurality of mail types have been developed and sold. For this reason, for example, when a mail is transmitted to the other party from the latest model having a service function of a new mail type, the transmission partner does not necessarily have all the mail functions of the same mail type as here.
[0007]
Therefore, it is necessary to select a mail type that can be communicated according to the transmission partner. In this case, it is determined which mail type the transmission partner can handle based on past mail exchanges and information, and the mail is transmitted. There was a problem that had to be. In addition, since a mobile communication terminal has a short replacement cycle, for example, the number of mail types that can be handled by replacing the transmission partner with a new telephone may increase. In this case, it is necessary to ask and memorize the mail types that can be handled by the other party, or to remember the mail types that come from the other party.
[0008]
Further, when searching for the telephone number of the mail transmission destination using the telephone book registration function, even if the mail type is determined in advance, all registered data registered in the telephone book becomes the search target. For this reason, the telephone number of the mail transmission destination must be searched from all the registered data regardless of the mail type, and there is a problem that the search takes time and the search efficiency is poor.
[0009]
The present invention solves such problems of the prior art, and can confirm the mail types that can be supported by the transmission partner without storing past mail exchanges and information, and for each mail type. An object of the present invention is to provide a telephone with a mail function that can search data of registered destinations.
[0010]
[Means for Solving the Problems]
In order to solve the above-described problems, the present invention provides a telephone with a mail function having a mail function capable of responding to a plurality of mail types capable of transmitting and receiving mails having different information types. Caller number detecting means for detecting the telephone number of the other party, telephone book registering means for registering, as data, mail types that can be used on the terminal of the other party in addition to the telephone number and name of the other party, Search means for searching for data registered in the registration means, and character transmission type identification means for identifying the corresponding mail type when a mail is received. The phone also receives the mail, more determined whether the telephone number of the caller who sent the email is detected caller ID detection unit, telephone number detection if detected Is registered in the phone book registration means, and if registered, the mail type identified by the character transmission type identification means is used as the registration data of the telephone number of the caller who sent the mail. have a mail type automatic registration means to be registered in the registration means, when performing the transmission processing of mail, e-mail type is specified when creating a new message, is the search means mail type is specified are registered in the telephone directory registration means The data in which the specified mail type is registered is searched as a search target from the stored data, and the mail is transmitted to the transmission destination selected from the search result.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Next, an embodiment of a telephone with a mail function according to the present invention will be described in detail with reference to the accompanying drawings. In this embodiment, a case where the telephone with mail function according to the present invention is applied to a PHS terminal will be described as an example.
[0012]
FIG. 2 is a functional block diagram when the telephone with mail function according to the present invention is applied to a PHS terminal. In FIG. 2, an MPU 20 is a control unit that controls the entire PHS terminal, and includes a microcomputer (CPU) 21, a ROM 22, a RAM 23, a flash memory 24, a clock source 25, and an I / O port 26.
[0013]
The microcomputer 21 operates in synchronization with the clock supplied from the clock source 25 and executes specified processing according to a program that defines the operation processing procedure stored in the ROM 23. That is, the microcomputer 21 executes call processing such as outgoing call processing or incoming call processing using the internal memory or the RAM 23, and also executes a service function or the like that the PHS terminal has as a standard.
[0014]
As such a service function, the PHS terminal of the present embodiment has a mail service function that can handle a plurality of mail types. Specifically, a short text email that transmits about 20 characters, a long text email that transmits about 1000 characters, an email that sends and receives electronic mail via the Internet via a mail center, or a text message on a pager It is possible to correspond to a mail type such as DTMF mail that transmits a message using a DTMF (Dual-Tone-Multi-Frequency) signal.
[0015]
The PHS terminal according to the present embodiment also has a phone book registration function that extends the normal phone book function and can register mail types that can be used on the destination terminal in addition to the destination phone number and name. Yes. The microcomputer 21 stores character information transmitted by the mail service function and data registered by the telephone directory registration function in the flash memory 24 which is a nonvolatile memory.
[0016]
The microcomputer 21 is connected to components other than the MPU via the I / O port 26, and exchanges signals and data. The key operation unit 27 is a key operation unit provided with a dial key or various function keys, and performs input of a telephone number and setting of various operation modes, for example, creation of a character message and transmission of mail.
[0017]
The display device 28 is a liquid crystal display unit that displays the telephone number input from the key operation unit 27, the display of contents corresponding to the operation of the function keys, the state of the telephone, and the like. Specifically, the display device 28 displays a screen for selecting a mail type when the mail function is activated, a screen for specifying a transmission destination, a screen for creating a character message, and the like. In addition, when specifying a mail transmission destination, if the mail search destination is searched from data registered in advance by the phone book registration function, the data corresponding to each selected mail type is selected from all registered data. Extracted and displayed.
[0018]
The vibration motor 29 (including the motor drive circuit) is a motor that is driven when the mode is set to notify the incoming call by vibration instead of the ringtone. The RF transmission / reception circuit 30 amplifies and frequency converts the signal received by the antenna 31 and outputs a demodulation signal to the BBIC 32 described later, and amplifies and frequency converts the audio modulation signal from the BBIC 32 to the antenna 31. An RF transmission circuit that outputs a transmission signal. The antenna 31 is connected to the RF reception circuit and the RF transmission circuit by a changeover switch (not shown).
[0019]
The BBIC 32 is controlled by the MPU 21 and modulates and demodulates a voice signal and an RF signal. The audio signal that is the output of the BBIC 32 is amplified by the AF circuit 33 and drives the speaker 34. The audio signal from the microphone 35 is amplified by the AF circuit 33, then output to the BBIC 32, modulated, becomes a high frequency signal, and is radiated from the antenna 31 through the RF transmission / reception circuit 30.
[0020]
In the PHS terminal shown in FIG. 2, the MPU 20 has a caller number detection function for detecting a telephone number of a caller of a call received when an incoming call is received. That is, when the CPU 21 receives the information including the telephone number of the calling party terminal from the I / O port via the antenna 31, the RF transmission / reception circuit 30 and the BBIC 32 at the time of an incoming call, the CPU 21 extracts the telephone number from the information and extracts it from the RAM 23. To remember.
[0021]
The MPU 20 also has a telephone directory registration function that can register, as data, mail types that can be used at the other party's terminal in addition to the other party's telephone number and name. FIG. 3 shows the format of data registered by the telephone directory registration function. As shown in FIG. 3, the data that can be registered in the phone book is a total of n items from the first to the nth item, and the name (for display), reading (for search), phone number, and corresponding mail type, respectively. Information and other additional information can be registered.
[0022]
Corresponding mail type information in the registration items of the phone book registration function is an item for registering mail types that can be handled by the terminal of the registration data. If this is possible, “1” is set by 1 bit. Note that in FIG. 3, the mail types are not specifically shown, but are set as the mail types 1 to 4, which are the above-described short text mail that transmits about 20 characters and long text mail that transmits about 1000 characters, respectively. The e-mail for sending / receiving e-mail via the Internet via the mail center, or the mail type such as DTMF mail for sending a text message to a pager is shown.
[0023]
In addition, other additional information includes information types that cannot be identified by the data received at the time of incoming call, such as home, company, FAX, other mobile phone numbers, etc. You can register. Then, as with other items (name, reading, telephone number, mail type), it is possible to search according to the type of registered content. These data registered by the telephone directory registration function are stored in the flash memory 24.
[0024]
Further, the MPU 20 has a search function for data registered by the telephone directory registration function. Specifically, when a desired mail type is specified from the mail types 1 to 4 shown in FIG. 3 at the time of mail transmission, only registered data of the specified mail type is extracted and displayed on the display device 28. At that time, the mail type that can be handled by each registered data is displayed on the display device 28 by a mark (icon) or the like.
[0025]
In this way, for example, when inputting the telephone number of the mail transmission destination from the data registered by the telephone directory registration function, only the other party that can correspond to the specified mail type is displayed as the search target, so that the desired transmission The destination can be searched in a short time. In addition, even if you search for an email destination without specifying the email type, the email type that the other party can handle is displayed with a mark etc., so you can see the email type that can be handled at a glance, and select the optimal email type You can select and send a message.
[0026]
Further, the MPU 20 has a character transmission identification function for identifying a corresponding mail type when a mail is received. The MPU 20 identifies the mail type by receiving the incoming subaddress information in which a text message or the like is stored when an incoming call is received. FIG. 5 shows the data format of the destination subaddress.
[0027]
As shown in FIG. 5, one octet of the incoming subaddress is 8 bits, 1 octet is the incoming subaddress information element identifier area, 2 octets are the incoming subaddress content length area, 3 octets are the extension / subaddress identification / EO / reservation area It has become. The destination subaddress shown in FIG. 5 conforms to RCR STD-28, which is the second generation cordless telephone system standard.
[0028]
In the case of a short text mail of up to 20 characters, it is stored in 20 bytes of 4 octets to 23 octets in a relationship of 1 octet = 1 character. For mail types other than short text mail up to 20 characters, identification information of long text mail up to 1000 characters, E-mail or DTMF mail is stored in 4 bytes of 4 octets to 7 octets. Therefore, the MPU 20 can determine the mail type by analyzing 4 bytes of 4 octets to 7 octets of the received destination subaddress.
[0029]
The MPU 20 also has a mail type automatic registration function for automatically registering mail types in the data registered by the telephone directory registration function. This function, when receiving a mail, determines whether the phone number of the caller terminal detected by the caller ID detection function is registered by the phonebook registration function, and if registered, character transmission type identification It is checked whether the mail type detected by the function is set to be compatible. As a result, if the mail type is not compatible, the setting is changed to be compatible.
[0030]
As described above, the mail type automatic registration function is a function for automatically updating the mail type shown in FIG. With this function, the operator can determine what type of mail the registered data terminal can handle by referring to the registered data without storing past exchanges or information. A message can be transmitted by an optimum mail type corresponding to the other party.
[0031]
Referring to FIG. 1, there is shown a flowchart showing the operation of the present embodiment at the time of an incoming call. When there is an incoming call (S100), the MPU 20 determines the mail type from the received destination subaddress (S102). The MPU 20 also determines whether or not a caller number has been sent when an incoming call is received (S104), and if a caller number has been sent, searches for whether or not this number has been registered by the phonebook registration function ( S106).
[0032]
As a result, when the caller ID is registered (S108), it is confirmed whether or not the mail type determined in step S102 is registered as an applicable mail type in the registration information of the caller ID. (S110). If it is not registered as a mail type that can be handled, this mail type is registered as a mail type that can be handled (S112), and the incoming call processing is continued.
[0033]
On the other hand, if it is determined in step S104 that there is no caller ID (S104), steps S106 to S112 are performed. If it is determined that there is no registration in step S108, steps S110 to S112 are performed. If already registered, step S112 is omitted and the incoming call process is continued.
[0034]
Referring to FIG. 4, there is shown a flowchart showing the operation of the present embodiment until a new message is created and transmitted. When a new message creation process is started and a mail type is designated (S400), the designated mail type is stored (S402). When a new message is created (S404) and the search function for data registered in the phone book is activated (S406), the mail type stored in step S402 is extracted from the registered data. Therefore, the transmission destination can be searched from the stored mail types (S408).
[0035]
If there is registered data corresponding to the mail type stored at this time (S410), the extracted search result is displayed (S412). When a destination is selected from these (S414), the message created in step S404 is sent to the destination selected in step S414 (S416). If there is no transmission destination in the displayed search results (S414), re-search is started (S418), the search start position is updated (S420), and the search is performed again with the stored mail type by returning to step S408. I do.
[0036]
If there is no registration data that can be used for the mail type or there is no registration data when the search is performed again (S410), if the end of the search is selected (S412), the fact that there is no corresponding data is displayed (S414). . If the search end is not selected in step S412, the process proceeds to step S420, the search start position is updated, and the stored mail type is searched (S408).
[0037]
As described above in detail, according to the present embodiment, it is possible to automatically register mail types that can be handled by the other party in the telephone directory and display the contents as marks. Therefore, even if mail types that can be transmitted / received to / from the other party are not stored from past exchanges or information, it is possible to check mail types that can be handled at a glance. In addition, when selecting the phone number input of the other party registered in the phone book when sending mail, the data that can be used for the corresponding mail type is extracted from all the data registered in the phone book. The search time can be expected to be shortened.
[0038]
In the present embodiment, the present invention is applied to a PHS terminal. However, the present invention is not particularly limited to a PHS terminal, and a caller number that can receive a telephone number of a mobile phone or a caller terminal when receiving a call. It can also be applied to a fixed telephone having a notification function. Also, in this embodiment, the presence / absence of correspondence of each mail type is indicated by 1 bit. However, for example, if the amount of information is 1 byte for each mail type (for example, 4 bytes if there are 4 mail types). In addition to the presence or absence of correspondence, for example, display mark type data can also be set for each mail type of each registered data.
[0039]
Furthermore, in the present embodiment, a message is created after a mail type is specified, so that registration data corresponding to the mail type can be searched from the telephone directory. However, the present invention is not particularly limited to this, and the message creation is made common, for example, the registration items of data registered in the phone book are displayed, and the user can arbitrarily set the registration items from among them. You may be able to. Further, the priority order may be arbitrarily set among a plurality of registration items, and the search results may be displayed in order of priority.
[0040]
