The present invention relates to a mobile telephone comprising a housing and a touch screen. According to another aspect, the present invention relates to a method for declining an incoming call on a mobile telephone

comprising a housing and a touch screen.

Mobile telephones, also known as mobile phones, cell phones, cellular telephones, cell phone and the like, become more compact and the numbers of functions performed by a mobile telephones increase. For example, the use of vibrate means on mobile telephones is already established whereas the use of a touch screen on a mobile phone is a more recent development.

Touch screens, also known as touch sensitive displays, form a user interface that allows users to easily interact with the various functions of the mobile telephone. For example, the use of touch screens eliminates the problem of adding more pushbuttons, overloading the pushbuttons with several functions or using complex menu systems.

A user is usually notified on an incoming call by use of a ringtone mode which provide a sound signal or by use of a vibrate mode which provides vibrations to the mobile telephone.

A vibrate mode on a mobile telephone, commonly provided by vibrate means, serves a practical goal:

notifying the user on an incoming event such as an incoming call without using a ringtone. As a result of this function, mobile telephones can remain in an Switched on mode' when the user is advised to avoid making noise. For example in a meeting room, school class, museum, library, cinema and the like. Normally, a vibrate mode is set by the user in the menu of the mobile phone or by switching a switch. However, besides the practical use, there are some drawbacks hindering the use of the vibrate mode. For example if the vibrate mode is insufficiently quiet or the mobile telephone is laying on a hard surface, vibrating the mobile telephone may create an annoying noise. This annoying noise may irritate the user and bystanders. An example is the scenario where, during a meeting, everyone's attention is fixed at the noise of a vibrating mobile telephone.

Accordingly, the user may have to turn off the mobile telephone or set the mobile telephone to a silent mode.

However, than the user is not longer notified on incoming events, and may miss for example an important incoming call.

When the mobile telephone is in the ringtone mode, the sound signal may be disturbing, and with conventional mobile telephones declining the incoming call and switching off the sound signal takes too long. Thus, the manner for declining the incoming call is not efficient.

Therefore, there is a need in the art for a mobile telephone that can notify the user on an incoming call, without having the above mentioned disadvantages of

disturbing bystanders.

It is therefore an object of the present invention, amongst other objects, to provide a solution to the above mentioned problems. This object, amongst other objects, is met by providing a mobile telephone according to the appended claim 1.

More specifically, this object, amongst other objects, is met by providing a mobile telephone comprising a housing and a touch screen, wherein the mobile telephone is switchable into a locked mode in which the touch screen is not responsive to an user input unless a predetermined operation is performed, wherein the mobile telephone is configured to receive an incoming call when the mobile telephone is in the locked mode and accept the incoming call after a predetermined user acceptance input, characterized in that the mobile telephone is also configured to decline the incoming call after a predetermined user decline input on the touch screen and/or housing while the mobile

telephone remains in the locked mode.

The term Mobile telephone' is used within the present context as a device which can make and receive phone calls whilst moving around a geographic area. Mobile

telephones which also provide several other computing capabilities are commonly referred to as smartphones.

The term housing' as used in the present context means the body of the mobile telephone, which encompasses the back and front sides as well as the edges of the mobile telephone.

The term ^x touch screen' or ^x touch sensitive display' as used within the present context means a display able to detect user inputs, such as a gesture, finger gesture, tap or finger tap on the touch screen and translate these detected user input into commands to be performed.

The term incoming call' as used in the present context means the stage wherein the present mobile telephone receives an incoming call and signals this incoming call to the user by for example a ringtone and/or vibrating means, but wherein the connection between the caller and the called one is not established yet. With regard to the present invention, the incoming call may receive the present mobile telephone via a mobile telephone network and/or via wireless mobile internet services such as a 3G mobile network (for example via a UMTS system) or local WIFI network. Preferably although, the present incoming call is received via a mobile telephone network such as Global System for Mobile

Communications (GSM), General Packet Radio Service (GPRS), Code Division Multiple Access (CDMA) , Evolution-Data

Optimized (EV-DO) , Enhanced Data Rates for GSM Evolution (EDGE) , 3GSM, Digital Enhanced Cordless Telecommunications (DECT), Digital AMPS (IS-136/TDMA) , and/or Integrated

Digital Enhanced Network (iDEN) .

The term locked mode' as used in the present context means a mode wherein the touch screen is not activated and not able to detect a user's input, unless a predetermined operation is performed. However, when the mobile telephone receives an incoming call, the touch screen is activated and able to receive user's input, although the mobile telephone was at time of receiving the incoming call switched into the locked mode.

Predetermined operation' as used in the present context means an operation which is detectable by mobile telephone, for example via the touch screen and/or housing, although the present mobile telephone is switched in the locked mode. Examples of predetermined operations are a predetermined user acceptance input and a user decline input. A predetermined user acceptance input is the input to accept the incoming call. A predetermined user decline input is the input to decline the incoming call. The present mobile telephone may detect the user acceptance input via the touch screen, but also via for example a keyboard such as QWERTY keyboard, if the present mobile telephone

comprises a touch screen and a keyboard. The predetermined user decline input may be on the touch screen as well as on the housing, or body, of the mobile telephone. The

predetermined user decline input can be detected via an accelerometer, gyroscope and/or via the touch screen. The accelerometer and gyroscope may detect movement of the predetermined user decline input on the housing and/or touch screen of the mobile telephone. The touch screen may detect the predetermined user decline input on the touch screen. Preferably, the present user decline input is detected via the touch screen, preferably without using an accelerometer and/or gyroscope.

Remaining in the locked mode' as used in the present context means that the present mobile telephone remains switched into the locked mode after declining an incoming call.

The mobile telephone provided by the present invention solves the above mentioned technical problem.

Specifically, the present mobile telephone provides a very efficient way for switching off the sound generating modes such as ringtone mode or vibration mode, since only a user decline input on the touch screen and/or housing is enough to decline the incoming call and, preferably, to switch these sound generating modes off.

The mobile telephone according to the present invention even allows stop ringing or vibrating the mobile telephone by touching the present touch screen and/or housing through the trousers when the mobile telephone is stored in a user's pocket. Thus, by using the present mobile telephone, the user is able to get notified on the incoming call by for example vibration, however, the user is able to reduce the disturbing noise of the vibrating mobile

telephone immediately.

According to a preferred embodiment, the present mobile telephone is characterized in that the mobile
