1. Field of the Invention
The present invention relates generally to electronic mail (email) processing systems that transfer email sent from a sender terminal to recipient terminals via a network. More particularly, the invention relates to an email processing system that forwards email to recipients by adding predetermined items of user information to the email.
2. Description of the Related Art
The proliferation of the Internet in recent years has promoted email-based data communications among terminals of different types. Email is a simple and quick device of conveying messages, since a message composed on a terminal by a user who can use email can be readily received by one or more recipient terminals once sent to a mail server via the Internet. Today, Internet-capable cellular telephones are among those email-supporting terminals, and many of their users exchange email messages with other cellular telephones, personal computers, and/or other like devices.
In some features provided by prior art email processing systems, when a user includes one or more links such as various addresses in message text, a recipient can activate these links at the recipient terminal. For example, when a function called “Mail To” is used, the recipient user specifies (i.e., clicks on) an email address written on the message text through the recipient terminal to give a reply to that email address immediately. If the recipient terminal is a cellular telephone, a function called “Phone To” can also be available. The recipient user, who is the user of the cellular telephone, similarly specifies a telephone number written on the message text to dial that telephone number immediately. These functions provide recipient terminals with ease for connection to links through a network, and hence make email more useful.
If a sender user utilizes the Phone To function when sending email to a user carrying a cellular telephone, the recipient user can call the sender user without looking up the sender user's telephone number, which is of great convenience. However, the sender user must add telephone number data to message text every time he/she sends email, which is troublesome.
Moreover, if a map information provider site on the Internet is utilized, a recipient user searches for map information corresponding to an address (hereinafter meaning strictly “place of residence” as distinguished from “email address”) written on message text so that a recipient user can have a map image around that address displayed on a recipient terminal. However, the sender user must again add text data representing an address to message text, and go through an operation of searching for map information around the address every time he/she sends email, which is likewise troublesome.
Thus, the prior-art email processing systems have involved time-consuming, troublesome operations of entering telephone numbers, etc. even if sender users utilize various link information-related functions when sending email.
The present invention has been made in view of the above circumstances. It is, therefore, an object of the invention to provide an email processing system and a mail server which can add useful information to email messages automatically without troublesome operation so that a recipient can, for example, dial a telephone number added to received email and/or view map information based on map link information added to received email.

Referring now to
In the above configuration, the terminal 1 may be, for example, a PC that includes hardware and software for email massaging to communicate with other terminals 1 or cellular telephones 2, and for browsing various information by accessing sites on the Internet. To use an email service, which will be described below, the user operating the terminal 1 must be added to a client database 31 incorporated in the mail server 3 to be a registered user.
The cellular telephone 2 generally provides traditional telephone call functions, as well as additional functions to access various Internet sites and send and receive email to and from other cellular telephones 2 and terminals 1. It should be noted that the cellular telephones 2 can be replaced with portable information terminals which can exchange data over a similar network.
Referring next to
The mail server 3 supervises the overall operation of the email service according to this embodiment. The mail server 3 incorporates the client database 31 that stores various information about clients who utilize the email service. The client database 31 is a user information storage device that stores user information about users who have been registered as clients of the email service. The mail server 3 receives email from the terminal 1, confirms the email as a message from a registered user referring to the client database 31, adds to the email only predetermined items of user information (which items will be described below), and then forwards the email to one or more recipient users with the predetermined items added to the email. The functions and processing to be performed by the mail server 3 will be detailed below.
The cellular telephone mail server 4 sends, receives, and stores email messages for email-capable cellular telephones 2. Thus, any email message under way between a terminal 1 and a cellular telephone 2 is to be routed through both the mail server 3 and the cellular telephone mail server 4.
The base stations 5 are arranged each at areas where the users of the cellular telephones 2 are located. The cellular telephone 2 can, after establishing wireless connection with an adjacent base station 5, conduct radiocommunication via the base station 5. Each base station 5 is connected to the Internet through a gateway (not shown), for Internet access by the corresponding cellular telephone 2.
The map database center 6 and the map information provider site 7 provide map information as their functions assigned to implement the email service according to this embodiment. In the map database center 6, the map information is accumulated and managed in a database while associated with position information (latitude/longitude information). The map information includes image data for displaying map images corresponding to a plurality of hierarchical layers of different scales. The map database center 6 performs, in response to a map information request submitted via the map information provider site 7, a search process, and the searched map information corresponding to the specified position information is transmitted to the specified recipient's email address via the map information provider site 7.
The map information provider site 7 is set up on the Internet to provide various information relating to specified position information via the Internet. The map information provider site 7 stores pertinent information such as addresses and landmarks associated with position information, and outputs the stored information upon demand. When a user accesses the site 7 and specifies position information, the site 7 requests the map database center 6 to search for map information corresponding to the specified position information.
Next, the email service provided by the email processing system according to this embodiment will be described. As previously mentioned, this email service is to be rendered to the users who have been registered to the client database 31. Thus, a user registration process and user information to be stored in the client database 31 will be described with reference to
As shown in the figure, the user registration page includes text data entry fields for entering user information for registration such as the user's email address, name, sex, age, telephone number, and address. A user enters these text data items to the corresponding fields directly, or, as to sex and age, selects data from the corresponding pull-down menus. The user then follows a predetermined operation to transmit the entered registration data to the mail server 3 via the Internet.
In receipt of the registration data, the mail server 3 accesses the map database center 6 to acquire latitude/longitude information and a link, which is a URL or uniform resource locator, corresponding to the latitude/longitude information, based on the address transmitted as the entered data from the user. The link is supposed to be the URL of the map information provider site 7 in this embodiment. Then, the mail server 3 sets the acquired latitude/longitude information and URL as map link information, and stores, in the client database 31, the user information including the entered data such as the user's telephone number and the map link information. From then on, every time the user logs in for the email service according to this embodiment, the mail server 3 references the client database 31 to acquire predetermined items of his/her user information.
Next, how a registered user sends email will be described, taking an example of a message originated from the terminal 1 and destined for the cellular telephone 2. First, the user starts an email processing application software through interaction with the terminal 1 to compose a desired message. The email service according to this embodiment processes the message in the following manner to implement the Phone To and Map Link functions.
The mail server 3 references the client database 31 to confirm that the received message was sent from a registered user, and then acquires telephone number data and map link information from the user information of interest stored in the database 31 as the above-mentioned predetermined items, and adds the acquired data to the received message. Specifically, as shown in
The mail server 3 then forwards the email message including such link information to the cellular telephone mail server 4. The cellular telephone mail server 4 associates the received message with a recipient's email address, and houses that message. When a user having the recipient's email address accesses the cellular telephone mail server 4 utilizing the email function supported by his/her cellular telephone 2, the server 4 sends that message which has been housed therein. As a result, the recipient cellular telephone 2 receives that message via the Internet, and the recipient user hence can view a screen such as shown in
Referring continuously to
On the other hand, to use the Map Link function, the user of the cellular telephone 2 operates the key subsystem 28 to select the map link information shown on the screen of
As shown in
As described above, the email processing system according to this embodiment can provide both a user sending email and a user receiving the email with a highly convenient email service. That is, on one hand, the sender user can dispense with the troublesome operation of inserting his/her telephone number, address, etc. into the text of an email message, and can send the message with such information automatically added to the text. On the other hand, the recipient user can recognize the telephone number, address, etc. that are added to the received message, automatically dial the telephone number and acquire map information from a site indicated by the map link information to display the map information on a screen by, for example, simply clicking on the telephone number and the URL, respectively. In addition, the email processing system can be operated on a commercial basis easily because it can be set up merely by providing the mail server 3 for connection to the Internet and because it renders services to registered users.
As an alternative to the email processing system according to the above-disclosed embodiment in which telephone number data and map link information are added to message text, only one of these information items may be added to message text. In this case, it may be arranged such that a sender user selects one item by operating the terminal 1 in a predetermined manner.
As another alternative to the email processing system according to the above-disclosed embodiment in which a recipient user uses the Phone To function to make a telephone call and the Map Link function to acquire map information, the invention may be applied even to the case where a recipient user receives email that includes a telephone number and an address respectively having nothing to do with the Phone To and Map Link functions. Even in this case, the recipient user can recognize the telephone number and the address on the email and the sender user can dispense with the troublesome operation of inserting the telephone number and the address, to their advantage.
As still another alternative to the email processing system according to the above-disclosed embodiment in which email is sent to a cellular telephone 2, email may be sent to diverse types of terminals, other than the cellular telephones 2. For example, email may be sent to portable information terminals having telephone functions. In this case, a map can be displayed on their display with better visibility than in the cellular telephones 2, although the sender and recipient users cannot have a telephone conversation. Additionally, the present email service can be rendered when one or both of the email sender and recipient are the terminals 1 such as PCs, or when one or both of them are the cellular telephones 2, and the invention can be applied to a variety of combinations.
As described in the foregoing, according to the invention, email is forwarded to one or more recipients with predetermined items of user information automatically added thereto, whereby a user sending the email can provide the recipients with useful information, without having to perform troublesome operations. The invention also allows the recipients to automatically make a telephone call and/or view a map image based on the predetermined items of user information which have been added to the email as mentioned above, whereby email become more convenient.
