           [0003]    2. Description of Prior Art  
           [0004]    In mobile phones a deleted item cannot be recovered after having being deleted. The deletion of items is, as anyone knows something that many times goes too fast and many times also unintentionally. A press on a button and something is gone forever. In mobile phones known today there is no way back. It is known from mail systems to have a folder with deleted items that can be recovered. The aim with this invention is to propose a trash-can for mobile phones, where the user of the mobile phone has the possibility to review the deleted items in the trash-can and to recover them if wanted. Due to the fact that mobile phones have a rather limited memory capacity it is necessary to provide the trash-can with some restrictions to facilitate the use of the phone.  
           [0005]    The claimed invention provides a mobile phone with a possibility for the user to recover deleted items of all kinds and to return the deleted item to its original location. Its also provides a mobile phone with a recovering function that can be defined by the user in its recovering time, order of deletion, operation etc.  
         SUMMARY OF THE INVENTION

     DETAILED DESCRIPTION OF THE INVENTION  
       [0019]    According to a first aspect the recovering management terminal according to the invention will be described with reference to a hand portable phone, preferably a cellular/mobile phone. A preferred embodiment of this phone is shown in FIG. 1, 2 and  3 , where a cellular/mobile phone is shown in perspective. As will be seen, the phone is provided with a front cover  2  having a window frame  3  encircling the protection window of the display assembly  1 . The cellular/mobile phone comprises a user interface having an on/off button  4  (shown in FIG. 2), a keypad  7 , a battery  14  (not shown), a display/LCD  1 , an earpiece  21  and a microphone  22  (not shown).  
         [0020]    The keypad  7  has a first group of keys  8  as alphanumeric keys, by means of which the user can enter a telephone number, write a text message (SMS), write a name (associated with the phone number), etc. Each of the twelve alphanumeric keys  8  is provided with a FIG. “ 0 - 9 ” or a sign “#” or “*”, respectively. In alpha mode each key is associated with a number of letters and special signs used in the text editing.  
         [0021]    The keypad  7  additionally comprises a menu selection key  9 , a up/down key  10 , and a cancel key  11 . The functionality of the menu selection key or NaviKey™  9  depends on the state of the phone. The NaviKey™  9  is used together with the up/down key  10 , where the selection/navigation is made by the NaviKey™  9  and the scrolling in the menus are made by the up/down key  10 . The functionality of the NaviKey™  9  changes depending on the menus and its present functionality is shown in a separate field in the display  1  just above the NaviKey™  9 . The cancel key  11  is used for delete an input, or cancel the current selection and jump to previous menu level.  
         [0022]    The menu selection key  9  is placed centrally on the front surface of the phone between the display  1  and the group of alphanumeric keys  8 . Hereby the user will be able to control this key  9  with his thumb. This is the best site to place an input key requiring precise motor movements. Many experienced phone users are used to one-hand handling. They place the phone in the hand between the fingertips and the palm of the hand. Hereby the thumb is free for inputting information.  
         [0023]    [0023]FIG. 4 schematically shows the most important parts of a preferred embodiment of the phone/terminal, said parts being essential to the understanding of the invention. The microphone  22  records the user&#39;s speech, and the analogue signals formed thereby are A/D converted in an A/D converter (not shown) before the speech is encoded in an audio part  20 . The encoded speech signal is transferred to the controller  18  (physical layer processor), which e.g. supports GSM terminal software. The controller  18  also forms the interface to the peripheral units of the apparatus, including RAM and ROM memories  17   a  and  17   b,  a SIM card  16 , the display  1  and the keypad  7  (from FIG. 1) as well as data, power supply, etc. The controller  18  communicates with the transmitter/receiver circuit  19 . The audio part  20  speech-decodes the signal, which is transferred from the controller  18  to the earpiece  21  via a D/A converter (not shown).  
         [0024]    The preferred embodiment of the phone of the invention is adapted for use in connection with a GSM network, but, of course, the invention may also be applied in connection with any phone network. It could be cellular networks, various forms of cordless phone systems or in multiple-band phones accessing sets of these systems/networks.  
         [0025]    The controller  18  is connected to the user interface of the mobile phone. Thus, it is the controller  18 , which monitors the activity in the phone and controls the display  1  in response thereto.  
         [0026]    Therefore, it is the controller  18 , which detects the occurrence of a state change event and changes the state of the phone and thus the display text. The user may cause a state change event, when he/she activates the keypad  7  including the menu selection key or keys  9 , and these type of events are called entry events or user events. However, the network communicating with the phone may also cause a state change event. These type of events and other events beyond the user&#39;s control are called non-user events. Non-user events comprise status change during call set-up, change in battery voltage, change in antenna conditions, message on reception of SMS, etc.  
         [0027]    Different embodiments of the invention will be described with reference to FIGS.  1  to  11  showing the various features and steps of handling deleted items. The recovering management terminal in a communication unit is basically included in the menu structure and will be explained in connection with the menu structure. The starting point in each embodiment is that the phone is in idle mode, which means that the phone is turned on and ready to be used for any possible operation. The idle mode display will differ from embodiment to embodiment depending on the number of soft-keys  9  or  13  that are used in each embodiment.  
         [0028]    In the embodiments shown are examples of items that can be retrieved from the recovery management terminal like: SMS, ringing tones, phone book entries, bookmarks, settings set, calendar entries, pictures, smileys and profiles. The recovery management terminal should however not be limited to the items shown, but be used for retrieving any form of deleted items like e-mail, voice memos, voice tags, games, operator icons etc. Also user-actions, like renaming a bookmark, moving SMS from one folder to another should be stored in the recovery unit to allow undoing of these actions.  
         [0029]    It needs to be pointed out that in most cases the deleted items are not physically deleted from the memory in the communication unit, but only the pointer or link in the application menu indicating said deleted item before being deleted. A pointer or link will instead be created in the recovery management terminal application pointing to the memory location of the deleted item. If the deleted item is recovered from the recovery management terminal the pointer or link will be re-established in the application menu where the deleted item was deleted from. There is however one exception and that is the SMS. The SMS are normally stored on the SIM card, but when they are deleted from the SIM card they are stored in the memory of the communication unit with a pointer or link to the recovery management terminal. Likewise the deleted SMS when recovered from the recovery management terminal will be physically moved to the SIM card. There could be other types of items that are moved between memories.  
         [0030]    The displays might have another size than shown in the embodiments, but to include the different functions in the recovery terminal the displays have been adjusted in the presentation of the functions to be clearer. The user of the mobile phone uses the up/down key  10  to scroll up or down to see all the functions available in one menu.  
         [0031]    The first described embodiment will be described in connection with the communication unit shown in FIG. 1, where the communication unit has one soft-key  9 , also called menu selection key or NaviKey™.  
         [0032]    An idle mode display  30  for the phone is shown in FIG. 5, which includes two bars indicating the signal strength  31  and the battery level  32 . Furthermore there is a time indication  33 , an identification  34  of the operator to which the phone is currently connected, and a label  35  indicating the present functionality (Menu: access to the Menu structure) of the soft-key  9 .  
         [0033]    In idle mode the user can select the deleted items function by pressing the soft-key  9  “Menu” (shown in FIG. 5) and scroll down with the up/down key  10  until display  1  indicates “Deleted items”, like in display  40  in FIG. 7. This display includes a header  41  indicating the mode of the display (“Deleted items”), a menu-level indication  42  in the upper right corner and a picture  44  (not shown) displaying a picture or like that describes the mode of the display.  
         [0034]    The menu-level indication  42  indicates the specified number of the menu currently being shown and can be used to jump directly to that menu without scrolling in the menus with the up/down key  10 .  
         [0035]    By pressing the soft-key  9 , “Select”, once more when display  40  “Deleted items” is shown, the deleted items function is activated, step  200 , and display  45  will appear, step  201 , indicating a list  46  with the different options. If the cancel key  11  is pressed instead, step  202 , the phone is brought back to idle mode (idle mode display  30 ), FIG. 5. In the list  46  the first option  47  “View” will be highlighted to indicate, which option is executed by pressing the soft-key  9  “Select”, step  203 .  
         [0036]    The first option in display  45  is “View”  47 , which is executed by pressing the soft-key  9 , step  203 . By pressing the up/down navigation key  10  the other possible options: “Undeleting”  48 , “Erase”  49  and “Settings”  50 , will be accessible and highlighted on the display instead of “View”.  
         [0037]    When “View”  47  is highlighted in display  45  the user selects it by pressing the soft-key  9  display  51  will appear, step  205 . The display  51  includes a list  52  of deleted items  53 .

If the cancel key  11  is pressed, step  251 , the phone is brought back to the previous display  45 . By pressing the soft-key, when “Memory status”  97  is highlighted the phone calculates the memory usage, step  252 , and the display  105  will appear, step  253 . The display  105  includes two headers  106  and  107 , a FIG. 108 and a label  35  indicating the present functionality (Back: return to the previous display) of the soft-key  9 . The upper header  106  indicates “x % free”, where x states the percentage of the memory that is unused. The lower header  107  indicates “y % used”, where y states the percentage of the memory that is used. The portion of free and used memory is also shown graphically in FIG. 108. If the soft-key  9  is pressed or if the cancel key  11  is pressed, step  254 , the phone is brought back to the previous display  95 .  
         [0047]    By pressing the soft-key  9 , when “Automatic delete”  98  is highlighted in display  95 , a display  109  will appear, step  255 . The display  109  includes a list  110  indicating different automatic delete-options  111 - 114  and a label  35  indicating the present functionality (Select: The selected setting will be set.) of the soft-key  9 . The different automatic delete-options are “Off”  111 , “On”  112 , “Interval”  113  and “Items”  114 . If the cancel key  11  is pressed while being in display  109  the phone is brought back to the previous display  95 , step  256 .  
         [0048]    If the user presses the soft-key  9  when option “Off”  111  is highlighted in display  109  the Deleted Items function is turned off, step  257  and every item that is deleted thereafter is permanently deleted and can not be recovered. A confirmation is shown in a separate display (not shown in figure), step  258 , before the phone return to display  109 , step  259 . If the user presses the soft-key  9  when option “On”  112  is highlighted in display  109  the Recovery/ trash-can function is turned on, step  270  and every item that is deleted thereafter is gathered and added to list  52  of deleted items  53 . A confirmation is shown in a separate display (not shown), step  271 , before the phone return to display  109 , step  272 .  
         [0049]    If the user presses the soft-key  9  when option “Interval”  113  is highlighted in display  109  a display  115  will appear, step  273 . The display  115  includes a list  116  indicating the different intervals  117 - 119  that can be set and a label  35  indicating the present functionality (OK: Set the selected interval for permanent deletion of the deleted items  53 ) of the soft-key  9 . The different intervals are “1 hour”  117 , “1 day”  118  and “1 week”  119 . By pressing the soft-key  9 , when “1 hour”  117  i s highlighted in display  115 , the interval for emptying the list  52  with deleted items  53  will be set to one hour, step  274 . Once every hour all deleted items  53  in list  52  will be permanently deleted, step  275 , and the items of list  52  will be removed, step  276 . After setting of interval to one hour, step  274 , the phone returns to display  109 , step  246 . If instead the cancel key  11  in display  109  is pressed the phone is brought back to the previous display  95 , step  277 . If the user presses the soft-key  9 , when “1 day”  118  is highlighted in display  115 , the interval for emptying the list  52  with deleted items  53  will be set to one day, step  278 . Once every day all deleted items  53  in list  52  will be permanently deleted, step  275 , and the items of list  52  will be removed, step  276 . After setting the interval to one day, step  278 , the phone will return to display  109 , step  246 . If the user presses the soft-key  9 , when “1 week”  118  is highlighted in display  115 , the interval for emptying the list  52  with deleted items  53  will be set to one week, step  279 . Once every day all deleted items  53  in list  52  will be permanently deleted, step  275 , and the items of list  52  will be removed, step  276 . The user will not be notified that the list  52  of deleted items  53  is emptied at the set interval, the emptying will be performed automatically. After setting of interval to one week, step  280 , will the phone return to display  109 , step  246 .  
         [0050]    If the user presses the soft-key  9  when option “Items”  114  is highlighted in display  109  a display  120  will appear, step  280 . The display  120  includes a list  121  indicating the different type of items  122 - 125  that can be set to be deleted first if the memory is full. The display  12  also includes a label  35  indicating the present functionality (Select: Set the selected type of item to be deleted first) of the soft-key  9 . The different types that specified here are “Oldest”  122 , “Message”  123 , “Ringing tone”  124  and “Calendar entry”  125 . It could naturally be any other type of items that are handled by the Deleted items function, but in the display  120  only four types have been shown. Another option not belonging to a type, which could be possible to add in the display, are the largest items. By pressing the soft-key  9  when “Oldest”  122  is highlighted the phone will set, step  281 , that the item  53  to be permanently deleted, step  247 , and removed from list  52 , step  248 , is the oldest item  53 , regardless of the type. The phone will thereafter show a confirmation display (not shown), step  284 , and return to display  109 , step  285 . If instead the cancel key  11 , in display  120 , is pressed the phone is brought back to the previous display  109 , step  286 .  
         [0051]    By pressing the soft-key  9  when option “Message”  123  is highlighted the phone will set, step  287 , that the item  53  to be permanently deleted, step  247 , and removed from list  52 , step  248 , is the oldest deleted message  53 . The phone will thereafter show a confirmation display (not shown), step  284 , and return to display  109 , step  285 . Or if the user presses the soft-key  9  when  
         [0052]    “Ringing tone”  124  is highlighted the phone will set, step  288 , that the item  53  to be permanently deleted, step  247 , and removed from list  52 , step  248 , is the oldest deleted ringing tone  53 . The phone will thereafter show a confirmation display (not shown), step  284 , and return to display  109 , step  285 . Or if the user presses the soft-key  9  when “Calendar entry”  125  is highlighted the phone will set, step  289 , that the item  53  to be permanently deleted, step  247 , and removed from list  52 , step  248 , is the oldest deleted calendar entry  53 . The phone will thereafter show a confirmation display (not shown), step  284 , and return to display  109 , step  285 . Another type selection of automatic delete setting can be performed or the cancel key  11  can be pressed, step  256 , bringing the phone back to the display  95 . Yet another pressing of the cancel key  11  brings the phone to display  45 . If the user wants to exit the Deleted items function entirely he/she can long-press the cancel key  11  and the phone returns to idle mode (idle mode display  30 ).  
         [0053]    If the user presses the soft-key  9 , step  301 , when “Type of view”  99  is highlighted in display  95 , a display  126  will appear, step  302 . The display  126  includes a list  127  indicating different view types  128 - 129 , i.e. how the information is displayed in the display. Display  126  also includes a label  35  indicating the present functionality (OK: The selected view type will be set.) of the soft-key  9 . The different view types are “Name, icon list”  128  and “Name, time”  129 . If the cancel key  11  is pressed while being in display  126  the phone is brought back to the previous display  95 , step  256 . When either of view type “Name, icon list”  128  or “Name, time”  129  is highlighted pressing the soft-key  9  will set the selected view type  128  or  129  as default, step  303  or  304 , and will be used thereafter. A confirmations display (not shown), step  305 , will be shown and the phone returns to display  95 , step  306 . An example of view type “Name, icon list”  128  is shown in display  130  and an example of view type “Name, time”  129  is shown in display  131 . Display  130  is a copy of display  51 , while display  131  includes only one deleted item  53 . To see other deleted items  53  the user can scroll up/down with the up/down navigation key  10 , and the phone switches to a new display  131  for each deleted item  53 . The display  131  shows a deleted item  53  having a name  54  of the deleted item  53 , an icon  55  indicating the type of the deleted item  53 , a label  72  indicating the deletion date and a label  73  indicating the deletion time. The display  131  also includes a label  35 , which indicates the present functionality (Option: How should the selected item be treated) of the soft-key  9 .  
         [0054]    The second described embodiment will be described in connection with the communication unit shown in FIG. 2, where the communication unit has two soft-keys  9 . It also differs from FIG. 1 in that the cancel key has been replaced by two call handling keys  12  and further includes a volume control key  5 .  
         [0055]    An idle mode display  30  for the phone is shown in FIG. 11, which includes two bars indicating the signal strength  31  and the battery level  32 . Furthermore there is a time indication  33 , an identification  34  of the operator to which the phone is presently connected, and two labels  35  indicating the present functionality (Menu: access to the Menu structure; Names: access to the Phone book) of the two soft-keys  9 .  
         [0056]    The functionality described in connection to the communication unit with one soft-key is the same as for the communication with two soft-keys, but is performed slightly different due to the difference in keys. The right soft-key  9  in the communication unit with two soft-keys replaces the functionality of the cancel key  11  in the communication unit with one soft-key. The functionality of the left soft-key is as shown is FIG. 9 and  10  and resembles the functionality of the single soft-key in the communication unit having one soft-key. The functionality of the menu selection soft-key  9  in the communication unit with one soft-key is taken over by the left soft-key  9  in the communication with two soft-keys  9 . One exception to this is in display  71  and  105  showing time of deletion and memory status respectively, where the right soft-key  9  is used to return to the previous display for the communication with two soft-keys  9  and not the left soft-key  9  as it would be according to the above-mentioned.  
         [0057]    The steps of the recovering management terminal as described in connection with communication unit having one soft-key  9  is therefore also valid for the communication unit having two soft-keys  9  and needs not to be repeated once more.  
         [0058]    In FIG. 3 is shown a communication unit having three soft-keys  9 , where the third soft-key is integrated in a roller key  13 . The communication unit having three soft-keys  9  differs from the communication unit having two soft-keys  9  in that the roller key  13  has replaced the up/down key  10 . The roller key  13  includes apart from the up/down navigation functionality, known from the up/down key  10 , a menu selection functionality. This menu selection functionality can be used parallel with the menu selection function of the left soft-key  9 . The user can choose any of these selection options without any difference in operation. The menu selection functionality of the roller key  13  is performed by pressing the roller key  13 , and the up/down functionality is performed by rolling the roller key  13  either up or down.  
         [0059]    The difference between communication unit having two or three soft-keys  9  is limited to one additional menu selection key  9 , but otherwise having the same functionality, also the steps of the recovering management terminal described in connection with the communication unit having one soft-key  9  are valid for communication unit having three soft-keys  9  and needs not to be repeated.  
         [0060]    The invention is not limited to the above-described examples or to the drawings showing examples of an embodiment, but can be varied within the scope of the appended claims. One possible feature of the invention could be that the items stored in a memory structure having rather limited capacity, e.g. the SIM card, can automatically be deleted from that memory structure and relocated to the memory structure of the recovery management terminal and having a link to the list of deleted items in the recovery management terminal. The deleted item from that limited memory structure could e.g. be the oldest item in the memory structure. In the embodiments shown the recovery management terminal has been shown as a separate application in the communication unit, but naturally it could be possible to have a recovery management terminal for each separate application of the communication unit.
