20130109439
The invention relates to a mobile station apparatus and a method for performing software functions in the mobile station apparatus. The invention relates in particular to a mobile station apparatus comprising a lockable keypad.
Existing portable mobile station apparatuses comprise a user interface that includes a keypad portion comprising several keys for employing the apparatus to be used by users, for instance for selecting a telephone number or for performing other functions, like showing the telephone numbers or other data stored in the memory.
What is known from prior art portable mobile station apparatuses is the use of the locking function of the keys to prevent the apparatus from functioning when the keys are unintentionally pressed down for instance during transportation or when the user himself/herself accidentally presses the keys. Pressing down a key or keys typically locks the keys. Such a prior art locking function of the keys is described in EP publication 453089. When the locking function is switched on in the method described in said publication, the function of all other keys except for the ones releasing the locking function is prevented, and it is still possible to answer incoming calls when the locking function is switched on.
The user interfaces of mobile station apparatuses as well as the uses thereof have lately been developed and diversified to a great extent. Information that may be interesting for the users can be stored in the memory of the apparatuses. What is also possible in a prior art mobile station apparatus is to retrieve information onto the apparatus display, for example from the Internet through a WAP browser, or to receive electronic mail and text messages.
However, in prior art portable mobile station apparatuses, the method for retrieving information onto the apparatus display comprises several consecutive phases, such as using keystrokes and/or employing several menus and submenus for retrieving the desired information. To retrieve a simple piece of information, such as a date, onto the display requires several consecutive keystrokes before obtaining the desired information onto the display. When the keypad lock is switched on, the retrieval of information becomes even more difficult, as the desired information cannot be retrieved before the keypad lock is switched off.
It is an object of the invention to provide a method and a mobile station apparatus implementing the method so that information that is interesting for the user can be easily obtained onto the apparatus display when keeping one or more keys pressed down while the keypad lock is switched on. This is achieved with a method for performing control functions in a mobile station apparatus comprising several externally accessible keys, one or more displays and means for locking the keypad. The method of the invention comprises the steps of detecting that one or more keys are pressed down while the keypad is locked, performing software functions when said one or more keys are pressed down while the keypad is locked and showing the result obtained after having performed the software functions on one or more mobile station displays.
The invention also relates to a mobile station apparatus comprising several externally accessible keys, one or more displays and means for locking the keypad. The apparatus of the invention comprises means for detecting that said one or more keys are pressed down while the keypad is locked, means for performing software functions when one or more keys are pressed down while the keypad is locked and means for showing the result obtained after having performed the software functions on one or more mobile station displays.
The preferred embodiments of the invention are disclosed in the dependent claims.
The method and system of the invention provide several advantages. The method of the invention provides a simple and rapid way to obtain such information for use that previously required employing several consecutive keystrokes and retrieving information using menus and submenus. The method of the invention also provides such a feature that the keypad lock of the apparatus does not have to be switched off while retrieving information onto the display. The method thus enables by means of a single keystroke to read the incoming electronic mail or to check the correct date. The method of the invention also allows obtaining simply and rapidly changing data from the Internet, such as stock exchange rates or sports results. The method of the invention complements the idea of the keypad lock. The protection employed during the keypad lock can be used, and at the same time views to various applications can be provided.
In the following the invention will be explained in more detail by means of preferred embodiments with reference to accompanying drawings, in which
The preferred embodiments of the invention can be applied to telecommunication systems comprising one or more base stations and a number of terminals communicating with one or more base stations. In some preferred embodiments of the invention the terminals may also comprise the possibility to employ short-range communication, such as a transmitter-receiver function implemented using for example a Bluetooth chip, or an infrared or WLAN connection. The terminal may be for instance a mobile phone or another apparatus comprising corresponding telecommunication equipment, such as a portable computer.
As is common in mobile station apparatuses, the function keys include keys for establishing and ending a call and a key to access the menu of the apparatus. Desired information can be retrieved onto the mobile station display either using the specific applications of the apparatus, such as a calendar, or from remote targets, such as the Internet. When a conventional mobile station apparatus is concerned, the user has to perform several consecutive keystrokes and scroll the menus on the display, if the user wants to obtain information that may interest him/her, such as SMS (short message service) message menus or dates, onto the display.
Conventional mobile stations allow storing various setting group functions, or user profiles, into the apparatus, on the basis of which the apparatus operates in a particular way. Changing the user profile enables the user to simultaneously affect several of the settings in the apparatus. The settings, which the choice of user profile affects, are typically for instance the ringing type (normal, soundless, beep, vibration), the ringing tone, the ringing tone volume, the SMS message alert tone and the keypad tones. An example of such a user profile can for instance be such that the strength of all the tones is set at maximum level. In another user profile all other sound functions except for the reception of an SMS message are soundless.
Selecting for instance two predetermined keys in consecutive order can lock the keys of the keypad 100. In a conventional mobile station apparatus the control unit 102 identifies when said two keys are pressed down and does not therefore react when another key is pressed down before the keypad lock is switched off. However, it is possible to answer incoming calls while the keypad is switched on by pressing any key when a call arrives. Emergency calls can also be carried out when the keypad is locked.
In a preferred embodiment of the invention the control unit 102 detects, also when the keypad 100 is locked, that predetermined keys are pressed and held down, and consequently the desired software functions can be performed. Thus, desired information can be obtained for example onto the display 104. In practice, pressing down a key when the keypad is locked results in that the software in the memory of the control unit examines whether the pressing of said key is associated with performing particular software functions. If this is the case, the control unit starts performing said software functions, and as a result thereof the desired information is for example conveyed onto the display. At first, the control unit studies from where the information belonging to a particular key is to be retrieved. If the information concerned, like the calendar or SMS messages, can be found for instance from the specific applications of the apparatus, the control unit retrieves said information onto the display. If, in turn, the information to be retrieved is externally accessible from a remote place, the control unit establishes a connection to the address, where said information is located and transmits the information onto the display. In a solution according to a preferred embodiment of the invention the control unit detects that the key is no longer pressed down. When the user releases the key, the apparatus again shows the normal display of the keypad lock.
Even though the mobile station apparatus may in the present solution react, when the keys are locked, to the keystrokes by carrying out software functions, the original protective meaning of the keypad lock function does not disappear. The keypad lock is used to prevent making calls or to access applications unintentionally, for example when the keys are pressed accidentally. However, the present solution only offers views to particular applications. A preferred embodiment of the invention allows determining the software functions to be carried out so that no additional costs are caused for the user. The user may for example determine himself/herself the locations of the pages to be retrieved so that no extra costs are created for retrieving the pages. On the other hand, if the software function requires the establishment of a network connection in order to be carried out, the user may set for instance price or time limits, within which the apparatus operates. It is also possible to determine the software functions to be carried out in such a manner that each time when a key is pressed down a network connection is not established; instead the information is retrieved from a cache memory, for example.
If the apparatus receives a call at the same time as it is transmitting information onto the display, the control unit interrupts the software function and returns to the standard locking state of the keypad, in which state calls can be answered by pressing any key. However, a solution according to a preferred embodiment allows obtaining information rapidly onto the display also during a call by pressing down a key or keys and by holding the key or keys pressed down. It is thus possible to rapidly check, also during a call, for example the information required by a client without unnecessary prolonging the call or interrupting the call while retrieving the information. The solution according to a preferred embodiment of the invention the software functions can also be carried out during a packet and circuit switched connection.
In the solution according to a preferred embodiment of the invention, the control unit 102 detects, while the keys are locked, that predetermined keys are pressed and held down, and consequently software functions are performed, resulting in that the desired information is obtained on either or both of the displays 104, 114. In the solution according to a preferred embodiment of the invention, the control unit 102 transmits information in accordance with the programmed functions to said key only onto the secondary display 114, for instance, and also maintains the information on said display, even though said key is released. Thus, the user may check at all times the interesting information stored in the secondary display 114. In the solution according to a preferred embodiment of the invention, a function can be programmed for a key, as a result of which a loudspeaker 112 sends a sound signal, when the control unit has transmitted the desired information onto the primary or the secondary display. While the keys are locked, the user may initiate the search controlled by the control unit for information from a desired destination by pressing down a key for a certain time, and then release said key and wait until the sound signal indicates that the information can be read from the secondary display, for example. In a preferred embodiment of the invention, the user may in addition to a sound signal select other signalling means to indicate for instance that the desired information is transmitted onto the display. Such signalling means may include for instance a physical indication, such as a vibrating alert, or a light signal, such as flickering lights on the display or the keypad.
Storing the software functions to be performed as a result of pressing down each key can be carried out using the user interface of the apparatus. The solution according to a preferred embodiment of the invention allows storing for instance the search for a calendar page for key one, the search for an Internet page for key two etc. The software functions to be performed can also be connected to form a part of the different user profiles of the apparatus defined by the user, for instance in such a manner that the information obtained as a result of performing functions belonging to a particular key in a particular user profile is transmitted for example only onto a secondary display while the sound signal indicates the arrival of the information, and in another user profile said information is transmitted onto both displays without a sound signal. In a preferred embodiment of the invention, it is possible to connect the performance of software functions to only particular user profiles in such a manner that the software functions can be performed only in particular user profiles. It is further possible to determine the software functions to be different for different user profiles.
Let us take a closer look at the example shown in the block diagram in
If it is detected in step 206 that the desired information is not found among the specific applications of the apparatus, the process proceeds to step 210. In such a situation, where information has to be retrieved from behind telecommunication or short-range connections, said information may for instance be the contents of an e-mail message, a WWW or WAP site or a piece of information found from such a separate apparatus to which a short-range wireless connection can be established. In step 210, it is examined whether the apparatus is in online or offline state. In the online state the mobile station continuously communicates with the network, in which case the desired remote information is searched for in step 212 using transceiver means and the information is transmitted onto the display. In the offline state an operating apparatus does not constantly communicate with the network. In step 214, it is determined whether a telecommunication or short-range connection has to be established in order to retrieve the desired information.
According to an embodiment of the invention, a user may set limits concerning the establishment of connections. The user may restrict the establishment of connections by determining for example that all information is retrieved from the cache memory. Another restriction could be such that a network connection is for example established at three-hour intervals in order to update the information; otherwise the information is retrieved from the cache memory. In accordance with an embodiment of the invention the user may determine that the network connection for updating the information is established only at specific times. According to another preferred embodiment of the invention the user may also determine restrictions according to price, for instance in such a manner that when the expenses exceed a certain limit, network connections cannot thereafter be established.
In step 218, a connection is established to a target outside the apparatus using transceiver means. If remote information has to be retrieved for example from a separate apparatus from behind a short-range connection, then a connection to said apparatus can be established using for instance a Bluetooth chip, or an infrared or WLAN connection. After establishing the connection in step 220, the desired piece of information is searched for, the connection is disconnected if necessary and the retrieved information is displayed on the display. In accordance with a preferred embodiment of the invention, the user can also select whether to disconnect the connection.
If it is detected in step 214 that the search for the desired information does not require the establishment of telecommunication connections, then the process proceeds to step 216. Such a situation may be created for instance when the desired information is stored into the cache memory of the apparatus. In step 216, said information is shown from the cache memory. As in the case of step 208, the performances of steps 212, 216 and 220 are interrupted, when the release of a key is detected or when a call arrives at the apparatus, in which cases the process proceeds to the keypad locking state. If the apparatus includes a secondary display in addition to a primary display, then the information can be stored for instance in the secondary display also when a call arrives or even after the key has been released.
Even though the invention has above been explained with reference to the example in the accompanying drawings, it is obvious that the invention is not restricted thereto but can be modified in various ways within the scope of the inventive idea disclosed in the attached claims.
