For example, as shown in FIG. 3C, when maintaining the original list, the user can continue reading the e-book (251). However, if the original list cannot be maintained, that is, the copyright set in the e-book is granted to only one user, the user cannot read the e-book until the sharing or rental of the e-book is terminated (252).

4 is a flowchart illustrating a method for sharing an electronic library of a mobile terminal according to the present invention.

In order to share the e-books on the sharing list with another user's mobile terminal, the other user may request an electronic library sharing request, and the user who receives the sharing request may permit sharing of the electronic library. For convenience of description, the mobile terminal of the user is called a first mobile terminal, and the mobile terminal of another user is called a second mobile terminal.

As shown in the drawing, when the second mobile terminal requests the sharing of an electronic library from the first mobile terminal (S101), the controller 180 of the first mobile terminal notifies the user that the electronic library sharing request has been received (S102). . For example, the sharing request message of the electronic library and an option for selecting whether to permit the sharing request may be output.

When the user who has received the notification permits the electronic library sharing request (YES in S103), the controller 180 of the first mobile terminal transmits the electronic library sharing permission signal to the second mobile terminal (S104). Upon receiving the library sharing permission signal, the second mobile terminal performs an access procedure with the first mobile terminal in a preset communication method (S105).

When the second mobile terminal and the first mobile terminal are connected as described above (S106), the first mobile terminal transmits the e-book list set as a sharing object in the electronic library to the second mobile terminal, and the second mobile terminal shares the sharing. It is possible to display the list of e-books (S107).

5A to 5D are exemplary views illustrating an electronic library sharing method of a mobile terminal according to the present invention.

When the user of the second mobile terminal operates the electronic library sharing request (or electronic library reading request) menu, the controller 180 receives information for the electronic library sharing request from the user. For example, as illustrated in FIG. 5A, the information for the electronic library sharing request may be a phone number 261 of the first mobile terminal or an ID (262) of the other party. Here, the controller 180 can display a screen for receiving the information.

The controller 180 of the second mobile terminal which has received the information for the electronic library sharing request transmits the electronic library sharing request signal to the first mobile terminal. The electronic library sharing request signal may be transmitted to a mobile communication network, the Internet, or a short range wireless communication (eg, Bluetooth, infrared). The electronic library sharing request signal transmission method may be set in advance. In addition, the controller 180 may display the electronic library sharing request state 263. For example, a message such as 'an electronic library sharing request' or 'an electronic library sharing request completed' may be output.

Hereinafter, a method of allowing the sharing of an electronic library in the first mobile terminal which has received the electronic library sharing request will be described.

As shown in FIG. 5B, the controller 180 receiving the electronic library sharing request signal outputs the electronic library sharing request message 271 to the display unit 151. In addition, a selection option (eg, yes or no) 272 for selecting whether to permit the sharing request is output. When the user permits the electronic library sharing request, the controller 180 transmits the electronic library sharing permission signal to the second mobile terminal. If the user rejects the electronic library sharing request, the controller 180 transmits the electronic library sharing rejection signal to the second mobile terminal.

The second mobile terminal receiving the electronic library sharing permission signal (or electronic library sharing rejection signal) outputs an electronic library sharing permission message (or electronic library sharing rejection message). For example, as shown in FIG. 5C, the controller 180 asks whether or not to access the electronic library of the first mobile terminal (eg, 010-000-1234 permits reading the library. Would you like to connect? ) 273 and its response options (eg, yes, no) 274. When the user of the second mobile terminal instructs to access the electronic library, the electronic library screen of the first mobile terminal is output.

In other words, it may be said that the first mobile terminal and the second mobile terminal are connected to each other in a network. For reference, a method of connecting a network of the first mobile terminal and the second mobile terminal is described only as an embodiment and is not intended to limit the connection method or procedure thereof.

When the network between the first mobile terminal and the second mobile terminal is connected as described above, the second mobile terminal displays a list of e-books set to be shared among the e-books in the electronic library of the first mobile terminal. ) Can be displayed. The e-book list displayed on the second mobile terminal may be displayed in the same format as the format (for example, an image format or a text format) set in the first mobile terminal. Or it may be displayed in a separate format set in the second mobile terminal.

When the shared e-book list is displayed on the display unit 151 of the second mobile terminal as described above, the user may select and download the desired e-book from the shared e-book. For example, as shown in FIG. 5D, when a user selects an e-book from the list of e-books (281), the controller 180 may provide basic information (eg, author, publisher, Title, content summary, memo) (282). In response, the user may determine whether to view the reference information. If you decide to read the e-book, you can download and read the e-book.

However, according to the digital copyright set in the e-book, the user of the second mobile terminal may also need to purchase a digital copyright (or license). If it is necessary to purchase a digital copyright (or license), the controller 180 can output an option for selecting whether to purchase the digital copyright (283). Accordingly, when the user selects to purchase the digital copyright, the controller 180 can directly access the digital copyright purchase website. The description of the digital copyright purchase method on the website will be omitted.

When downloading the shared e-book as described above, the user of the second mobile terminal can also view the additional information attached to the e-book. For example, the additional information may include at least one of 'bookmarking information recorded by the user of the first mobile terminal in an e-book', 'memo information', 'highlight information', or 'additional content'. Of course, the additional information may be selected according to the user's selection. For example, when only the 'bookmarking information' is shared among the additional information, the second mobile terminal may read only the contents of the e-book and the bookmarking information.

In the above-described embodiment, the method for reading the shared e-book list of the first mobile terminal in the second mobile terminal has been described. On the contrary, the shared e-book list of the second mobile terminal may be read in the first mobile terminal. have.

6A to 6C are exemplary views illustrating an e-book rental method of a mobile terminal according to the present invention.

In the present embodiment, the e-book that can be rented can be re-rented not only by the e-book purchased by the user, but also by the user from the 'e-book rental server'. For reference, the e-book rental server is a server that lends a limited period of digital copyright set in the e-book, and performs a function of renting the e-book at a cost corresponding to the period (or rental period). It's a server. Therefore, the user pays the fee set by the rental period and owns the right to read the e-book only during the rental period, as in the method of purchasing the e-book. When the rental period has elapsed, the digital copyright is automatically terminated.

Therefore, when a user (first user) rents the borrowed e-book again to another user (second user) or shares it with the second user, it is possible to rent or share it only within the rental period. In addition, when extending the rental period of the e-book, either the first user who borrowed the e-book from the server or the second user who re-rented the e-book from the first user corresponds to the extension period. You have to pay extra.

Hereinafter, an embodiment related to a method of renting the e-book will be described.

The first e-book rental method is a method of renting an e-book in response to the rental request in the first mobile terminal that received the rental request from the second mobile terminal, similarly to the method of sharing the e-book list. For example, when an e-book rental request is made from the second mobile terminal to the first mobile terminal, and the first mobile terminal receiving the e-book rental request permits the rental, the second mobile terminal accesses the first mobile terminal. You can rent an e-book of your choice.

A second e-book rental method is a method of directly renting an e-book from a first mobile terminal to a second mobile terminal. For example, the user of the first mobile terminal may re-rent the e-book borrowed from the 'e-book rental server' to the user of the second mobile terminal. That is, during the remaining rental period of the rented e-book, the rental period of the e-book is transferred from the first mobile terminal to the second mobile terminal. Alternatively, the electronic book owned by the user of the first mobile terminal may be loaned to the user of the second mobile terminal. Hereinafter, the specific method is demonstrated.

As shown in FIG. 6A, the user of the first mobile terminal selects an e-book to be rented from the 'e-book' (291), and the rental period remaining in the e-book (e.g., last -10 days, remaining time) -20 days) (292). The e-book rental recommendation (or e-book rental period transfer) menu 294 may be operated. According to the menu operation, the controller 180 receives information for the e-book rental recommendation from a user (294). For example, the information for inviting e-book rental may be a phone number 295 of a second mobile terminal or an ID 296 of a counterpart. Here, the controller 180 can display a screen for receiving the information.

The controller 180 receiving the e-book rental information transmits an e-book rental invitation (or e-book rental period transfer) signal (or message) to the second mobile terminal. The e-book rental solicitation signal may be transmitted through a mobile communication network, the Internet, or short-range wireless communication (eg, Bluetooth, infrared). In the method of transmitting the e-book rental invitation signal, one of the communication schemes may be preset. The controller 180 can display a transmission state of the e-book rental solicitation signal. For example, it may output a message such as 'The e-book rental recommendation is complete'.

Hereinafter, a method of borrowing an e-book from a second mobile terminal that has received the e-book rental invitation signal will be described.

As shown in FIG. 6B, the controller 180 which has received the e-book rental solicitation signal has received an e-book rental recommendation message (eg, 010-000-1234) from the display unit 151. Do you want to connect?). Then, a selection option (eg, yes or no) 312 for selecting whether to access the first mobile terminal to rent the e-book is output.

If the user rejects the e-book rental, the controller 180 transmits the e-book rental rejection signal to the first mobile terminal. However, if the user of the second mobile terminal wants to borrow the e-book ('Yes'), the controller 180 transmits the e-book rental reception signal to the first mobile terminal.

As illustrated in FIG. 6C, the second mobile terminal may access the first mobile terminal to receive and display brief information of the recommended e-book (321). For example, the brief information of the e-book recommended for rental may include a title of the book, an author, a storyline, a memo written by the user, or rental period information.

If the user of the second mobile terminal sees the brief information and decides to borrow the e-book (OK key input), the controller 180 can download the e-book directly from the first mobile terminal. Alternatively, the electronic book may be downloaded from the 'e-book rental server' (322). Even if the e-book is downloaded from the first mobile terminal or downloaded from the e-book rental server, the rental period remaining in the e-book is not changed. Therefore, when the e-book is downloaded, a message for guiding the remaining rental period may be output (323). If the e-book to be rented is owned by the user of the first mobile terminal, the user may directly set the rental period.

As described above, the e-book borrowed from the first mobile terminal is managed in the 'electronic library' of the second mobile terminal. In addition, since the e-book is rented and the digital copyright of the e-book is transferred to the second mobile terminal, it is automatically deleted from the 'electronic library' of the first mobile terminal. On the contrary, when the rental period ends, the copyright of the e-book is returned to the first mobile terminal and automatically deleted from the second mobile terminal.

7A and 7B are exemplary views illustrating an e-book presenting method of a mobile terminal according to the present invention.

The user of the first mobile terminal may present the e-book purchased by the user to the user of the second mobile terminal. The e-book may be downloaded directly from the 'e-book purchase server' to the first mobile terminal and then directly presented to the second mobile terminal or directly from the 'e-book purchase server' to the second mobile terminal.

An icon for accessing the e-book purchase server, hereinafter, a widget icon, is disposed on a standby screen.

In addition, the controller 180 may receive a greeting to be sent to the other party together with the e-book to be presented. If the user does not input a greeting, the controller 180 receives a default greeting (eg, 010-000-1234 presents the e-book). It can be entered automatically.

In addition, the controller 180 may provide basic information of the e-book to be presented (eg, title, summary, author, publisher, location where the e-book can be downloaded (eg, mobile phone number or server address), e-book Code] can be automatically transmitted. That is, when the input of the e-book to be presented and information about the other party is completed, the controller 180 may transmit a 'gift providing message' including the greeting and basic information of the e-book to the second mobile terminal. The gift providing message may be transmitted through a mobile communication network (eg, SMS, MMS, E-mail), the Internet, or short-range wireless communication (eg, Bluetooth, infrared).

Referring to FIG. 7B, the controller 180 of the second mobile terminal outputs the present message 421 and a selection option 422 for selecting whether to receive the e-book present. In response to the user receiving a gift, the controller 180 can access a location (eg, a first mobile terminal or an e-book purchase server) where the e-book can be downloaded. That is, the e-book corresponding to the e-book code may be downloaded by accessing the first mobile terminal or the e-book purchase server. The second mobile terminal can display the e-book download state (423).

When the e-book is presented from the first mobile terminal to the second mobile terminal as described above, the digital copyright of the e-book is transferred to the second mobile terminal. Therefore, the first mobile terminal does not have the authority to read the present e-book. However, the record of the present e-book can be kept in the electronic library of the first mobile terminal.

Meanwhile, the user of the second mobile terminal may refuse the gift of the e-book. For example, if the e-book to be gifted is already in the second mobile terminal, or if the e-book to be gifted is not the user's interest, the user of the second mobile terminal may reject the gifted e-book. have.

When the gift is rejected as described above, the rejection message (eg, the gift is rejected) may be transmitted to the first mobile terminal. The rejection message may be automatically transmitted from the second mobile terminal or may be transmitted from the e-book purchase server. If the gift is rejected as described above, the payment of the e-book may be automatically canceled (424). Alternatively, the user of the first mobile terminal receiving the rejection message may directly cancel the e-book.

8A and 8B are exemplary views illustrating a method of purchasing an e-book of a mobile terminal according to the present invention.

As shown in Fig. 8A, a user must purchase an e-book in order to present, rent, recommend, or share the e-book. The e-book can be purchased by connecting to an e-book purchase server, and there is a method of searching for and purchasing an e-book desired by the user.

Alternatively, as illustrated in FIG. 8B, a method of collectively purchasing e-books selected from an e-book list (for example, a recently published book list, a best seller list, a classic list, or a celebrity recommended book list) may be used. There is this. The e-book list may be automatically updated at specific periods or may be downloaded by connecting to an e-book purchase server (or book list service server).

The e-book list may be output on the standby screen as a widget icon, and the corresponding e-book list may be edited by selecting the widget icon (431). For example, in the editing step, the e-books to be purchased may be selected from the best seller list (432). In addition, the selected e-books may be purchased or a purchase may be recommended or presented to a specific counterpart (433).

At this time, the purchase cost of the e-book may be directly paid by the user or the other party. Payment of the purchase cost may be made in the e-book purchase server.
