Description

Selecting and transmitting files to terminal}

The present invention relates to controlling a terminal suitable for processing files, and more particularly to transmitting multimedia files to a wireless terminal.

The characteristics of modern mobile station models include not only conventional telephone functions but also various multimedia functions that enable the creation and processing of multimedia files and their transfer to other mobile stations or computers, for example for further processing. Mobile stations of this type typically include a digital camera, and images generated by the digital camera can be transmitted to other communication devices, for example using e-mail or multimedia messaging services (MMS). The fact that these multimedia mobile stations have become common has made the sharing and distribution of images and other multimedia files between different terminals very popular.

A typical situation of sharing images and other multimedia files is when a set of images or other multimedia files are stored on the first terminal and the user of the second terminal wants a copy of one or more of them. So the simplest way to share the multimedia files is to provide the multimedia files that the user of the first terminal has stored in some other storage medium such as a mobile station or a computer, and the user of the second terminal selects what he / she wants. It is. After this, the desired multimedia files are transmitted to the second terminal via a communication connection. However, the method of transferring these multimedia files can be problematic because it requires that both users exist.

To address this, multimedia file transfer methods have been developed which are based on storing images or other multimedia files generated by a wireless terminal on a separate server, where other users browse the multimedia files and download them to their terminals. Access permission to load is granted. One such configuration is disclosed in WO application 02/097672.

In addition, this type of configuration has drawbacks, because granting access to outsiders always represents a security risk. Another problem is that a second party needs to establish a wireless connection to the server, need to browse large multimedia files over a substantially slow wireless connection, and also download the multimedia files to the terminal via the connection. This is a significant cost to the second party.

Methods and means are now provided for implementing the method to substantially reduce the disadvantages of the problems described above. As different aspects of the invention, methods, wireless terminals, servers and software products are provided, which are characterized by what is stated in the independent claims.

Some embodiments of the invention are provided in the dependent claims.

The present invention provides a group of multimedia file identifiers on a server in a message format in which identifiers can be indicated by a user of a second terminal to select and order at least one or a portion of the multimedia files from a server using a response message. And transferring the multimedia files from the first terminal to the second terminal.

According to one embodiment, a response message comprising an identifier of at least one selected file or part of the file is received by the server from the second terminal.

According to one embodiment, the files are multimedia files, the multimedia files or some of them are compressed to a smaller size and they are arranged in one message according to the message format used for transmission to the second terminal. do.

According to one embodiment, a unique identifier for each of the multimedia files is formed for transmission with the group of multimedia files, the unique identifier being separable as a parameter instructable by the user of the second terminal.

According to one embodiment, if the group of multimedia files is copied to a network server prior to the transmission of the message to the second wireless terminal, the network address of the network server is added to the message to order the multimedia files. do.

The configuration of the present invention provides the advantage that the user of the first terminal can easily, quickly and inexpensively provide image files and other multimedia files to be shared with other users of the terminals. Another advantage is that the mobility of any of the terminals is not limited in such a way that the users of the terminals must meet or any one of the users must establish a connection to a server that requires access to browse the files. It is not.

Furthermore, according to one embodiment, the second (receiving) terminal identifies the received message as a particular message intended for sharing of multimedia files and the compressed multimedia files and / or their identifiers are derived from the message. Separate into separate fields to be provided to the user of the terminal for selection using the pointer of the terminal.

Subsequently, in response to the selection made by the user of the second terminal, an order request is made for the compressed multimedia files or multimedia files including their identifiers, and the request includes the multimedia files. Transmitted to a server, so that the server can be the first terminal or a network server.

The multimedia files or their network addresses specified in the request are from the server to the second terminal or as attachment of at least one message, such as an email message or MMS message or as a file transfer over a data link, of the second terminal. It is sent to the address specified by the user.

The configuration of the present invention provides the further advantage that the user of the second terminal can very easily form an image request from the reduced images provided. In order to browse the files, the user of the second terminal does not need to establish a connection to the server requiring access rights, and she / he can browse the files available on his terminal and request the desired files.

The invention will now be described in more detail through preferred embodiments with reference to the attached drawings.

In the following, the invention will be described by way of example using embodiments particularly related to sharing digital image files between users of terminals. However, the present invention is not limited to only (still) image files, and the same procedure is also applicable to other document files and other multimedia files such as digital video or audio files.

1 shows a wireless terminal MS such as a mobile station with a camera function CA. Mobile station generally refers to an apparatus comprising means for implementing wireless data transmission. Such devices include devices capable of data transmission with public land mobile networks, such as GSM / GPRS networks or third generation (eg 3GPP) networks. It should be noted that the present invention is also applicable to mobile stations that lack the camera function but have the ability to download multimedia files via an available communications connection. It should be noted that the present invention is also applicable to mobile stations equipped with a camera, wherein the camera is not integrated into the mobile station, and a camera for generating image information is attached to the mobile station by wire or wirelessly. It should be further noted that the present invention is not limited to mobile stations, and that it is possible to apply the present invention to portable or fixed personal computers, various mass memories, printers and other electronic devices suitable for file processing.

The mobile station MS comprises a central processing unit (CPU), a memory (MEM) and an I / O system (I / O). All necessary information is stored in the memory MEM of the device. The memory MEM comprises, for example, a read-only memory portion formed of ROM memory and a read-write memory portion formed of RAM and / or flash memory, for example. Through the I / O system (I / O), the device communicates with other devices, the network and the user, for example. In particular, the I / O system includes a transceiver (Tx / Rx) adapted to transmit and receive data transmissions in accordance with various wireless data transmission protocols via an antenna (Ant). A user interface (UI), which is part of the I / O system (I / O), includes the necessary interfaces, such as displays, keys, loudspeakers, and / or microphones for communicating with the user. Information received from other components of the apparatus is sent to the central processing unit (CPU), which includes one or more processors and processes the received information as desired.

The mobile station MS of FIG. 1 also includes a camera CA that can function using any known digital imaging technique. The camera CA converts light into charges in the image sensor, defines the RGB values for the dots and converts them to digital format. In addition to still images, it should be noted that the camera CA may also store video images. The central processing unit (CPU), for example, processes the digital-format image information, compresses it and stores it in the memory MEM. The mobile station of FIG. 1 includes means for generating and / or downloading digital sound material in addition to or instead of the camera. The sound material may for example be music files compressed in the MP3 compression format.

The signaling diagram of FIG. 2 illustrates a configuration according to a preferred embodiment of the present invention for transferring multimedia files between two wireless terminals, such as mobile stations. The example of FIG. 2 uses digital still images recorded by camera CA as the multimedia files. The user of the first terminal MS1 selects 200 files to be transmitted to the user of the second terminal MS2 for her / he to browse from the image files stored in the memory of the terminal (200). The thumbnail images (thumbnails) are formed of the selected images, for example by compressing the original image files. The unique identifier is for example for each miniature image as a check sum calculated from the image data or as an identifier calculated based on the terminal identifier (e.g. IMSI or IMEI code) and the time stamp of the original image. Is formed. The purpose of the unique identifier is to individually identify each selected image file and to link the miniature image to the original image file.

A uniform message is then formed 202 with the reduced images and their identifiers in a format that allows separation of the reduced images and / or their identifiers from the message for further processing. For example, an MMS message can be used as the presentation format of the message with the identifiers as thumbnails and separate text fields attached to it as one embedded image file. Correspondingly, an email message can be used as a similar message, with an embedded image file of thumbnail images also attached to the email message as an attachment. The reduced images may also be maintained along with the identifiers as individual image files attached to a structured document format, such as an HTML, XHTML or XML document. Other data may also be attached to the message, such as a field for greeting text, the size of the original image files, the browsing order of the thumbnail images, the recommended connection format for the transmission of the original files, and the like. After the message is generated, it is preferably sent to the second terminal MS2 using the available wireless data transmission method (204).

When the second terminal MS2 receives the message, it preferably identifies (206) the message as a specific message for sharing multimedia files. For the processing of messages, the receiving terminal may include a plug-in suitable for the purpose and capable of automatically identifying such messages. The terminal MS2 is in such a way that the reduced images and / or their identifiers are displayed from the message to the user of the terminal (208) and separated into separate fields that the user can select using the pointer of the terminal. Unpack the received message. The user selects the pointer, for example by pointing to the miniature images or their identifiers, and after selecting the desired images, the user confirms the selection. Thereafter, an image request is formed to send back to the first terminal MS1 an image request including identifiers of desired reduced images or actual reduced images, the image request being generated by the first terminal MS1. Is sent (210).

The first terminal MS1 examines the identifiers of the reduced images in the received image request and retrieves corresponding original image files from the memory (212). Thereafter, the required original image files are sent to the second terminal MS2, for example, as a file transfer over a data link or as an attachment to a message (or messages), such as an email message or an MMS message. 214. Preferably the file transfer can take place, for example, using the GPRS protocol and the File Transfer Protocol (FTP) or Hypertext Transfer Protocol (HTTP) data transfer with the WAP or TCP / IP protocol on top of it as the transfer protocol. Also, if a high quality communication connection or a less expensive connection is desired for the transfer of the image files, the transfer of the image files may be postponed later.

The above procedure provides the advantage that the user of the first terminal can easily, quickly and advantageously provide image files and other multimedia files for sharing with other users of the terminals. Correspondingly, it is very simple for the user of the second terminal to form the image request from the provided reduced images. The procedure allows full mobility for both terminals without the need for users of the terminals to meet or any one of them having to establish a connection to a server requiring access rights to browse the files.

A second embodiment of the present invention is shown in the flowchart of FIG. In this embodiment, the starting point is to store the image files of the first terminal in a network server rather than the memory of the terminal, from which the image files are provided to other users of the terminals for sharing. Accordingly, the user of the first terminal MS1 selects 300 files that she / he wants to share with other users of the terminals from image files stored in the memory of the terminal. The image files are thus transmitted or copied to the network server SR (302). Thereafter, a message for sharing multimedia files is generated from the images to be provided for sharing as described above, in which case the message is reduced images formed of the original images, their unique identifiers and possibly the Include other data attached to the message. In this embodiment, address information for the network server is also attached to the message to send the image request. In the example of FIG. 3, the message is generated at the first terminal MS1, but it can also be generated controlled by the first terminal MS1 at the server SR. After the message is generated, it is transmitted 304 to the second terminal MS2.

The second terminal MS2 receives the message 306 and identifies the message as a specific message for sharing multimedia files. The terminal MS2 displays the reduced images and / or their identifiers from the received message to the user of the terminal 308 and unpacks them into individual fields that the user selects using the terminal's pointer. Address information of the network server is also separated from the message. Thereafter, an image request including identifiers of the desired reduced images or actual reduced images is formed and sent 310 to the network server SR in this embodiment.

The network server SR checks 312 identifiers of the reduced images in the received image request and retrieves corresponding original image files from the memory (312). Thereafter, the requested original image files are transmitted 314 to the second terminal MS2 as a file transfer over a data link or as an attachment to a message. It is also possible for the server SR to send the network addresses of the images in the image request to the second terminal MS2, such as only IP-based URL addresses, wherein the user of the terminal MS2 You can use the terminal's network browser to browse the original image files and download them.

In this embodiment, the user of the first terminal can free some of the memory of the terminal by preferably transmitting image files provided for sharing to the network server. However, the user of the terminal controls the generation and transmission of a message for sharing the multimedia files. The second terminal also does not need to establish a connection to a server that requires access rights to browse the files.

One variation on the second embodiment described above is another embodiment, in which the terminal MS2 making the image request to the server SR sends the original image files to the server SR2. Request transmission to some other storage medium, such as the network server of the user of terminal MS2, not MS2). In the flowchart of FIG. 3, the image request 310 sent by the second terminal MS2 also includes the network address of the storage medium to which the original image files are to be sent, and correspondingly, the server SR. Transmits the image files 314 to the network address instead of the second terminal MS2.

When the image files are transmitted from the server to the second terminal, the administrator of the server may bill the transmission of the images to the user of the second terminal. Price parameters are defined for the image files, the price parameters are summed based on the order made by the second terminal, and billing information of the order is formed from them. Billing may occur, for example, in such a way that payment for the transmission of the images is added to the telephone bill of the user of the second terminal. Alternatively, if the payment is made directly between the user of the second terminal and the sender of the images, it is possible to use a credit card or e-payment. Of course, costs may arise for the user of the second terminal from the transmission of the images over a communication connection. The user of the first terminal may also be billed for storing the images on the server.

In the transfer of a file from one terminal to another, the application can serve as an interface to the service. Thus downloading the application to the terminal can be changed in a manner known in nature. Moreover, the application can record the image file transfers performed and based on the information thus collected, users can be billed, for example, in their telephone bill. The application may also be a rental application, in which case a rent is charged for using the application at the terminal.

In order to transfer the original image files between the terminals or between the terminal and the server, in some cases (short physical distance) it is possible to use an infrared-based data transmission such as a short range wireless connection such as a Bluetooth or WLAN connection or an IrDA connection. In this case, data transmission over the mobile network is avoided, and thus no data transmission cost is incurred.

4A and 4B illustrate by simplified user interface view the generation of a message of the invention intended for sharing files on the first terminal. In FIG. 4A, image files in the memory of the terminal are displayed to the user by the image application of the terminal. The user of the terminal selects from the stored image files which files he wishes to attach to the message intended for file sharing.

4B shows an example of such a message. Miniature images of selected files are attached to the message. Moreover, a unique identifier is formed for each of the thumbnail images and appended to the 'imageinfo' field, by which the selected image files are identified and the thumbnail images are linked to the original image files. . The message of FIG. 4B also includes a field for greeting text.

In the above, the present invention is described by way of example through the sharing of still image files, but the procedure of the present invention can be applied to any multimedia files correspondingly. For example, attaching a short clip of just one image or a large video or audio file that can be compressed to a much smaller size using more efficient compression than normal if necessary for the above message for sharing multimedia files. It is possible. Especially for large multimedia files, it may be desirable to use the procedure according to FIG. 3, where the multimedia files to be shared are stored on a network server. Moreover, the procedure can be applied to different document files, for example a short summary can be attached to the message for sharing multimedia files. The procedure is particularly applicable to presentation graphics files (e.g. PowerPoint (trademark) files), in which case the receiver can use it to order the required slides in their original format. Slides can be attached to a message for sharing multimedia files.

In a wireless terminal, the functions of the present invention may preferably be implemented by software (SW) downloaded to the terminal, wherein the software is executed by the mobile station (MS) when executed on a central processing unit (CPU). To perform the operations according to. The functions of the software SW may be distributed to several individual software components that communicate with each other. The software may be stored on any storage medium, such as a hard disk of a personal computer (PC) or a CD-ROM disk, from which the software is transferred to a memory (MEM) of the terminal (MS). Can be downloaded. The software can also be downloaded over the network, for example using the TCP / IP protocol stack. It is also possible to use hardware solutions or a combination of hardware and software solutions to implement the inventive means.

Thus, the software SW1 in which the first terminal MS1 controls the sharing of files such as multimedia files with other terminals is preferably a sub-process for controlling the storage of files on the memory medium. Software code portions such as; And a portion of software code for transmitting identifiers describing the contents of a group of files to a second terminal via a message, the identifiers using a response message from at least one of the files from the memory medium. Directed by the second terminal to select and order a file or a portion of the files.

Furthermore, the software SW1 preferably comprises a portion of software code for compressing multimedia files or portions of the multimedia files to a smaller size; And a software code portion for arranging the compressed multimedia files into one message according to the message format used for transmission to a second terminal. In addition, the software SW1 may preferably comprise a portion of software code for generating a unique identifier for each of the multimedia files for transmission with the corresponding multimedia file in the message, wherein the unique identifier is It is separable as a parameter directable by the user of the second terminal.

The operation of the software SW1 and the first terminal MS1 controlled by the software can be described with reference to the flowchart of FIG. 5. First, a user of the first terminal MS1 selects files that she / he wishes to provide for sharing with other terminal users from files stored in the memory of the terminal 500. Thereafter, a memory medium to be used to share the files is selected (502); In other words, it is determined whether to use the memory of the terminal or the memory of the network server. When the user selects the memory of the network server, the files selected for sharing are transferred or copied to the network server SR (504). Thereafter, a message of the present invention intended to share files is formed 506 of files selected for sharing, and address information of the network server is also appended to the message to send a file request. If (502) the memory of the terminal is selected above, a message of the present invention intended to share files is also formed (508), in which case the address information is any of the terminal, such as the subscriber number of the mobile station. Address information.

In the flowchart of FIG. 5, the remaining portions of the steps are described together in such a way that the next step is the transmission of the message 510 from the selected memory medium to one or more terminals. Thereafter, the memory medium receives a file request (512), and corresponding original files are retrieved from the memory medium in response to the file request (514). The requested original files are sent 516 to the requesting terminal as a file transfer over a data link or as an attachment to a message.

Correspondingly, the software SW2, in which the second terminal MS2 can order files such as multimedia files, preferably comprises a software code portion, such as a sub-process, for displaying the files; Software code portions for identifying the message received by the terminal as a specific message for sharing files; Software code portion for separating the compressed files and / or their identifiers in the message into separate fields; And a software code portion for displaying the fields to a user of the terminal for selection using the pointer of the terminal.
