Definitions

  • the present invention relates generally to distribution of information and data elements in local area networks.
  • the invention relates to a method and a terminal set up to browse data elements in a dynamic local area network.
  • Mobile terminals such as mobile phones and so called PDAs (Personal Digital Assistant), are constantly increasing in capacity. This is the case for functionality like storage capacity, size and resolution of display, and possibilities for connecting to a local area network or other terminals in the neighbourhood. It has become possible to establish connections between such terminals with radio links which are adapted for shorter distances than for example the mobile network itself, which a terminal may be connected to. With such a radio link, connection may be established between terminals which are less than for example 100 m from each other.
  • the object of the present invention is to provide a method for and a terminal which is arranged for generation and presentation of hyperlinks for data elements in connected terminals, on the display of the mobile terminal, in such a way that the user of the terminal can browse these data elements.
  • this terminal shall present an arbitrary selection of available data elements.
  • a real time database in each terminal is kept of which elements are available at any time. This means that there is kept a list of second available terminals and available contents in these.
  • hyperlinks will be generated which refer to data elements which are stored in second terminals which are connected with the first terminal through a dynamic local area network.
  • the hyperlinks are presented for a user of the first terminal, to give the possibility for browsing the data elements in second connected terminals.
  • hyperlink means a graphic indication, which is enabled for marking, on a screen, in the form of text, logo, picture or similar, and upon activation or marking by a user, it represents a link to an information content, like a data element.
  • a dynamic network means a network with a character that makes the number of terminals not decided and often changing.
  • the terminals that make the network will further typically be different or "unknown" terminals, as the network changes.
  • a dynamic local area network means a dynamic network which is characterized by the fact that the connection between the terminals of the network is limited at least by distance between the terminals.
  • a terminal may send a request to another terminal, asking whether it has contents of interest, ie. whether is has specified types of contents. Eventually the terminal will ask another terminal about a list of all available contents, and thereafter filter out contents of a desired type. According to the invention the terminal receives information about all available contents, however there is not performed any filtering out of certain types of content.
  • Fig. 1 shows a principle sketch of terminals in a local area network Figs 2a -.2l ⁇ .rshow principle sketches of system parts of a terminal according to the invention.
  • Fig. 3 shows an example of presentation of hyperlinks in the display of a terminal.
  • Fig. 1 shows a principle sketch of terminals in a local area network.
  • a first terminal 1 for example a mobile phone, is sufficiently close to three second terminals 3, so that a radio link is established between the first terminal 1 and the three second terminals 3.
  • the circle indicates an area 5 surrounding the first terminal 1 where the conditions for establishment of a radio link with the first terminal are present.
  • the area 5 will mainly move accordingly.
  • the extension and form of the area 5 will indeed depend on obstacles such as for example buildings.
  • the example shown in Fig. 1 we assume an additional terminal 3' which moves into the area 5 from outside.
  • a new radio link is established between the first terminal 1 and the new second terminal 3 ⁇
  • the example only shows a few terminals.
  • the first terminal 1 may have connections with a much larger number of second terminals 3. This will for example be the case when the terminal 1 (mobile phone) is in the middle of a crowd of people, like at a concert, a sport event or in a crowded street.
  • the first terminal 1 Since the number of terminals that the first terminal 1 is connected with constantly changes, the first terminal 1 must have functionality for maintaining an updated list of second available terminals 3. Further functionality is needed for providing an updated list of available contents in these second terminals 3. Since the first terminal 1 also will act as another second terminal 3, as seen from another terminal, the first terminal 1 will also have functionality which provides similar access from other terminals. However in this example we look at the functionality of the first terminal 1 vis-a-vis the second terminals 3, to whose data elements the first terminal 1 is granted access.
  • the second terminals may be mobile terminals, like mobile phones, but may also be fixed localised terminals. Examples of this may be second terminals arranged in a shop to inform customers about goods, proposed food recipes, special offers etc. Another example may be other terminals arranged in museums, zoological gardens and the like, to inform visitors.
  • FIGS. 2a - 2c show a principle sketch of three process steps for providing the above mentioned updated list of connected second terminals and list of available contents in these.
  • Each of Figures 2a - 2c illustrates the same three process steps 100, 200 and 300, but at three consecutive points in time.
  • the terminal 1 repeats continuously each of the three process steps, for example every five seconds.
  • the process step 100 is executed to provide an updated list of available second terminals 3.
  • the second terminals 3 send at regular intervals heartbeat (HB) signals with the intention to signal the presence, respectively the availability of these terminals.
  • the first terminal 1 sends similar HBs to second terminals 3.
  • the terminal 1 receives three HBs 101.
  • the terminal has received information that there are three second terminals 3 that it has connection with.
  • the terminal 1 receives an additional HB 101. This happens because the second terminal 3', as mentioned while referring Fig. 1 , now has arrived in the area 5, so that it may establish connection with the first terminal 1.
  • the connection with the second terminal 3 is regarded as lost.
  • the first terminal 1 must maintain an updated list of available contents in the available second terminals 3. In this example this is provided in the process steps 200 and 300.
  • a second terminal 3 When a second terminal 3 had its contents changed, it sends out an announcement message 301 about this to all available terminals. This may for example happen if the second terminal 3 has deleted a file, or has downloaded a new file which is made available for other terminals.
  • Fig. 2a it is illustrated that such an announcement message 301 is received by the first terminal 1 in the process step 300.
  • Fig. 2b it is shown that the received announcement message 301 is processed by the first terminal 1 in the process step 200.
  • the process step 200 it is decided that the first terminal 1 wishes to know about the change that the second terminal 3 announced with the message 301.
  • the first terminal 1 sends out a request message 201 to the actual second terminal 3, where it asks the second terminal 3 to send a response message with information about what is changed in its available contents.
  • this response message 202 is received by the first terminal 1.
  • the first terminal 1 uses the information in this response message 202 to update the list of available contents in the available second terminals 3.
  • the information in this list may preferably be meta data like the name of the files, their size and type, and for example information like artist name if the file is a melody/song.
  • Fig. 2b shows as described that the first .terminal has received one additional HB 101 from a second terminal 3' which has entered the area 5.
  • the first terminal 1 sends out a request message 201 to the new second terminal 3'.
  • the first terminal 1 will receive a response message 202 from the new second terminal 3 ⁇ and use the information in this to update the list of available contents.
  • the operation for updating the list of available contents may also be performed in alternative ways.
  • the above described way has an advantage in that it enables different types of optimizations, such as a reduction of the time the radio links between the terminals are used.
  • the user will download the data element, or file, to which a hyperlink 4 is referring, by activating the hyperlink 4.
  • the data element is downloaded to the first terminal 1.
  • Such a download may be in the form of transmission of the whole data element from a second terminal 3 to the first terminal 1.
  • the download may be in the form of so called streaming, where the data element is shown or presented at the first terminal 1 at the same time as the element is transferred from a second terminal 3.
  • the download may be terminated, for example if the user does not wish to have the rest of the element presented on his/hers terminal.
  • only one hyperlink referring one data element from each of a plurality of second terminals 3 is presented.
  • the first terminal 1 chooses a random data element from available second terminals 3, and accordingly only one from each second terminal 3. If the first terminal 1 only has contact with a few second terminals 3, the selection function will go through the list of available elements once more, and choose more elements, to fill the display 2 with hyper links 4.
  • Another selection function could choose random data elements from the whole amount of available data elements, without consideration of which of the plurality of second terminals 3 they are available fror ⁇ ,
  • a third selection function could prioritize presentation of the data elements that become available latest. The function would then rank the second terminals 3 in the order corresponding to how long they have been in the data base, or list, of available second terminals 3. Alternatively if the first terminal 1 receives information that a second terminal 3 has got a new data element, as described above, this data element may be prioritized.
