Description

Phone architecture partitioning

FIELD

Embodiments of this invention relate to phone devices. BACKGROUND

From a consumer perspective the stand by time of a mobile phone is always to short. Technically a lot of energy is wasted during idle mode or basic usage mode when user is not interacting or only using basic functionalities but the processor is active and consumes energy without delivering related consumer experience.

Convential phone architectures use a single main phone application engine taking care of cellular communications. Such a main phone application engine provides a variety of complex functionalities and requires a complex application processor. This shows the drawback that this application processor has a significant power consumption even when only minimal actual functionality is needed.

SUMMARY OF SOME EMBODIMENTS OF THE INVENTION

Further reduction of power consumption of phones is desirable.

According to a first exemplary embodiment of an aspect of the invention, a method is disclosed, said method comprising providing a basic phone application comprising a set of basic phone functionalities in a first state of the apparatus, and providing an enhanced phone application comprising a set of enhanced phone functionalities in a second state of the apparatus, wherein the set of enhanced phone functionalities comprises at least one extended phone functionality compared to the set of basic phone functionalities.

According to a second exemplary embodiment of an aspect of the invention, an apparatus is disclosed, which is configured to perform the method according to an aspect of the invention, or which comprises means for providing a basic phone application comprising a set of basic phone functionalities in a first state of the apparatus, and means for providing an enhanced phone application comprising a set of enhanced phone functionalities in a second state of the apparatus, wherein the set of enhanced phone functionalities comprises at least one extended phone functionality compared to the set of basic phone functionalities.

According to a third exemplary embodiment of an aspect of the invention, an apparatus is disclosed, comprising at least one processor and at least one memory including computer program code, the at least one memory and the computer program code configured to, with the at least one processor, cause the apparatus at least to perform the method according to an aspect of the invention. The computer program code included in the memory may for instance at least partially represent software and/or firmware for the at least one processor. Non-limiting examples of the memory are a Random-Access Memory (RAM) or a Read-Only Memory (ROM) that is accessible by the least one processor.

According to a fourth exemplary embodiment of the first aspect of the invention, a computer program is disclosed, comprising program code for performing the method according to an aspect of the invention when the computer program is executed on a processor. The computer program may for instance be distributable via a network, such as for instance the Internet. The computer program may for instance be storable or encodable in a computer-readable medium. The computer program may for instance at least partially represent software and/or firmware of the at least one processor.

According to a fifth exemplary embodiment of the first aspect of the invention, a computer-readable medium is disclosed, having a computer program according to an aspect of the invention stored thereon. The computer-readable medium may for instance be embodied as an electric, magnetic, electro-magnetic, optic or other storage medium, and may either be a removable medium or a medium that is fixedly installed in an apparatus or device. Non-limiting examples of such a computer-readable medium are a RAM or ROM. The computer-readable medium may for instance be a tangible medium, for instance a tangible storage medium. A computer-readable medium is understood to be readable by a computer, such as for instance at least one processor. In the following, features and embodiments pertaining to all of these above-described aspects of the invention will be briefly summarized. For instance, the set of basic phone functionalities comprises at least one of voice call functionality, short message service functionality, and low-speed data transmission via a radio-frequency (RF) interface of the apparatus. For instance, said low-speed data transmission may represent a circuit switched or packet switched data transmission with a data rate less than 250 kbit/s, e.g. less than 100 kbit/s or less than 50 kbit/s, wherein said low-speed data transmission for instance may represent a cellular radio transmission like a CSD or GPRS (e.g. 2.5G) or EGPRS (e.g. 2.75G) transmission or any other well-suited low-speed cellular based data transmission.

Accordingly, as an example, the basic phone application may be assumed to implement only basic phone functionalities and thus may be considered to represent a basic phone application engine.

Furthermore, the apparatus can be operated in a second state in which the enhanced phone application comprising a set of enhanced phone functionalities is provided, wherein the set of enhanced phone functionalities comprises at least one extended phone functionality compared to the set of basic phone functionalities.

For instance, the set of enhanced phone functionalities may comprise at least a part of the functionalities of the set of basic phone functionalities or the complete set of basic phone functionalities. Additionally, the set of enhanced phone functionalities comprises at least one extended phone functionality, wherein this at least one extended phone functionality is not part of the set of basic phone functionalities of the basic phone application. As an example, the at least one extended phone functionality may comprise at least one of a high-speed data transmission via the radio frequency interface of the apparatus, position detection, video output on a display, camera functionality, microphone functionality, applications configured to perform access to the internet, and an application configured to pre-program speech tags. When the apparatus is in the first state and thus the basic phone application is provided, the enhanced phone application may be completely deactivated. Thus, as an example, the basic phone application may be implemented in apparatus to function as being totally independent from the enhanced phone application, wherein in the first state the at least one extended phone functionality may be not instantiated. Accordingly, as an example, in the first state the enhanced phone application may be considered to be shut down and thus the at least one extended phone functionality may not even provided as idle functionalities when the basic phone application is provided in the first state. For instance, without launching the enhanced phone application, the at least one extended phone functionality can not be made available and can not be provided.

As an example, the enhanced phone application may be realized at least partially as hardware and/or or at least partially as software, wherein the hardware part of the enhanced phone application may be deactivated in the first state, and/or wherein the software part of the enhanced phone application may be deactivated in the first state, e.g. by means of stopping the software part and/or closing the software part.

Thus, the apparatus is not configured to provide one of the at least one extended phone functionalities when the apparatus is in the first state.

The basic phone application may be considered to represent an application tailored to provide only basic functionalities of a phone, as described above, wherein this basic phone application may be considered or be implemented as a low complexity phone part which might, for instance, be designed for minimum or minimized power consumption compared to the power consumption of the an enhanced phone application.

For instance, the basic phone application may have access to the essential subsystems of the apparatus, wherein these essential subsystems may comprise at least one of an identification module, which might be configured to receive a subscriber identification module, e.g. a SIM card, and a RF interface, and an input/output (I/O) interface, and a security module. For instance, the basic phone application may only have limited access to the RF interface and/or to the (I/O) interface. As an example, the basic phone application may only have access to a cellular RF interface of the RF interface, wherein the RF interface may provide further wireless interfaces like WLAN or short range communication (e.g. Bluetooth) or near field communication (e.g., RFID-based communication) which may be not accessed may by the basic phone application. The short range communication may be considered to provide a shorter communication range via the air than WLAN systems, e.g. a range between 0m and 20m, preferably between 0m and 10m, or less than 10m, and the near field communication may be considered to have a shorter communication range via the air than near filed communication systems, e.g. a range between 0m and 2, preferably between 0m and lm, or less than lm.

In contrast to the basic phone application, the enhanced phone application may have complete access to all essential subsystems and may have access to at least one further subsystem of the apparatus, wherein this at least one further subsystem may be implemented by at least one further module.

For instance, the at least one further module(s) may comprise a module configured to detect the position of the apparatus, e.g. based on received satellite signals, wherein this module may be configured to detect the position in accordance with a GPS or

GLONASS or any other well-suited satellite based positioning system. Thus, the at least one extended phone functionality of the enhanced phone application may comprise a position detection functionality which might use the mode for detecting the position of the apparatus. Or, as an example, the further module(s) may comprise an accelerometer, wherein the at least one extended phone functionality of the enhanced phone application may comprise a functionality for obtaining the speed and/or acceleration of the apparatus.

Accordingly, in the first state only the basic phone functionalities of the basic phone application are provided which enables minimized power consumption since the at least one processor of the apparatus provides the basic phone application but not the enhanced phone application. In particular, as an example, this minimized power consumption may be achieved since in this first state the at least one extended phone functionality of the enhanced phone application may not be instantiated on a processor of the at least one processor and, for instance, may not be held in the background of an operating system running on one of the at least one processor.

If the apparatus is switched from the first state to the second state, for instance, the enhanced phone application may be launched or activated and then full extended phone functionality can be provided, wherein power consumption is increased compared to the first state.

Furthermore, for instance, a handover functionality may be provided in order to perform the transition from the first state to the second state and a handover functionality may be provided in order to perform the transition from the second state to the first state.

According to an exemplary embodiment of an aspect of the invention, the basic phone application is implemented to function as being totally independent from the enhanced phone application in the first state.

Thus, for instance, in the first state the basic phone application can provide the set of basic phone functionalities event though the enhanced phone application is at least partially deactivated.

According to an exemplary embodiment of an aspect of the invention, in the first state the enhanced phone application is at least partially deactivated. For instance, in the first state the enhanced phone application may be completely deactivated. For instance, if the enhanced phone application represents software running on a processor, this software may be stopped and/or may be cancelled on the processor. According to an exemplary embodiment of an aspect of the invention, the set of enhanced phone functionalities comprises at least a part of the functionalities of the set of basic phone functionalities. Thus, as an example, the set of basic phone functionalities of the basic phone application may be considered as a part of the enhanced phone application, i.e., for instance, the basic phone application may be considered as a part of the enhanced phone application. For instance, in the first state the enhanced phone application may be partially deactivated, wherein this partial deactivation may be directed to the at least one extended phone functionality provided by the main application, and thus, the remaining part of the application which is still provided may then represent the basic phone functionality. According to an exemplary embodiment of an aspect of the invention, in the first state the basic phone application is implemented as a basic phone application engine, and in the second state the enhanced phone application is implemented as an enhanced phone application engine. Thus, as an example, different application engines may be used for providing the basis phone application and for providing the enhanced phone application. In the first state, the basis phone application engine is running and the enhanced phone application engine is deactivated, wherein in the second state, the main application engine is running while the basis phone application may be still run or may be deactivated.

According to an exemplary embodiment of an aspect of the invention, in the second state at least a part of the set of enhanced phone functionalities is provided by a main processor of the at least one processor of the apparatus. For instance, said at least a part of the set of enhanced phone functionalities may comprise the at least one extended phone functionality which is provided by the main processor without comprising the remaining functionalities of the set of enhanced phone functionalities, or it may comprise the complete set of enhanced phone functionalities.

As an example, the main processor may provide a silicon area associated with this at least a part of the set of enhanced phone functionalities to be provided by the main processor in the second state. For instance, this silicon area may be configured to provide the enhanced phone application or at least a part of the enhanced phone application in the second state.

Furthermore, for instance, providing the at least a part of the set of enhanced phone functionalities by the main processor in the second state may be understood that a software for providing said at least a part of the set of enhanced phone functionalities is operated on the main processor, e.g. on the above mentioned silicon area, wherein in the first state this software may be deactivated.

According to an exemplary embodiment of an aspect of the invention, in the first state at least a part of the set of basic phone functionalities is provided by the main processor.

Thus, as an example, in the first state the basic phone application may be provided by the main processor.

For instance, as a first example, when the apparatus operated in the first state and is then operated in second state, during the transition process from the first state to the second state the basic phone application may be deactivated on the main processor, wherein this deactivating may comprise stopping the basic phone application and/or cancelling the basic phone application, or switching of a silicon area of the main processor associated with the basic phone application, and the enhanced phone application may be launched and then run on the main processor. Furthermore, for instance, during the transition process from the second state to the first state the enhanced phone application is deactivated on the main processor, wherein this deactivating may comprise stopping the enhanced phone application and/or cancelling the basic phone application, or switching of the silicon area of the main processor associated with the enhanced phone application, wherein for instance this silicon area associated with the enhanced phone application at least partially or completely differs from the silicon area associated with the basic phone area, and the basic phone application may be launched and then run on the main processor when the apparatus is in the first state.

Or, for instance, as second example, in the second state the basic phone application may be considered to represent a part of the enhanced phone application, and during the transition process from the first state to the second state the basic phone application the at least one extended phone functionality of the enhanced phone application is launched, wherein the at least one extended phone functionality and the basis phone application and may be considered to represent the activated or instantiated, i.e., implemented enhanced phone application, wherein the basis phone application may still provide the set of phone basis functionalities in the second state. Furthermore, for instance, during the transition process from the second state to the first state the enhanced phone application is deactivated on the main processor, wherein this deactivating may comprise stopping the at least one extended phone functionality and/or cancelling the at least one extended phone functionality such that remaining application corresponds to the basic phase application. For instance, said deactivating the enhanced phone application may comprise switching of a silicon area of the main processor associated with the at least one extended phone functionality of the enhanced phone application, wherein for instance this silicon area associated with the at least one extended phone functionality of the enhanced phone application at least partially or completely differs from a silicon area associated with the basic phone area.

According to an exemplary embodiment of an aspect of the invention, in the first state at least a part of the set basic phone functionalities is provided by a secondary processor of the apparatus.

Thus, the apparatus may comprise at least two processors, wherein these at least two processors comprise the main processor and the secondary processor.

For instance, the complete basic phone application may be provided by the secondary processor in the first state.

The basic phone application can be operated independently from the enhanced phone application due to the use of the secondary processor. As an example, the secondary processor may represent a low power processor compared to the main processor, wherein the secondary processor may for instance be implemented in low power silicon technology compared to the silicon technology of the main processor, and/or wherein the secondary processor may be operated at a lower clock frequency and/or lower voltage compared to the main processor. Furthermore, for instance, when the apparatus is in first state, the main processor may be configured not to provide the enhanced phone application. As an example, in the first state the enhanced phone application may be completely (or at least partially) deactivated on the main processor, wherein this deactivating for instance may comprise stopping the enhanced phone application engine on the main processor, or removing the enhanced phone application engine on the main processor, or deinstalling the enhanced phone application from the main processor, or at least partially switching of the main processor, e.g., switching of the silicon area of the main processor being associated with the enhanced phone application, or completely switching off the main processor.

According to an exemplary embodiment of an aspect of the invention, the main processor is at least partially shut down the main processor in the first state.

For instance, the silicon area associated with the enhanced phone application may be shut down in the first state, wherein the basic phone application may be provided by another silicon area associated with the basic phone application of the main application, or may be provided by the optional secondary processor.

According to an exemplary embodiment of an aspect of the invention, the set of basic phone functionalities comprises at least one of: voice calls, short message service, low-speed data transmission via a radio frequency interface of the apparatus.

According to an exemplar)' embodiment of an aspect of the invention, the at least one extended phone functionality of the set of enhanced phone functionalities comprises at least one of: high-speed data transmission via a radio frequency interface of the apparatus, position detection, video output on a display, camera functionality, microphone functionality, applications configured to perform access to the internet, an application configured to program speech tags. According to an exemplary embodiment of an aspect of the invention, the apparatus is operated in a power saving mode in the first state.

For instance, in this power saving mode the basic phone application may only have access to the essential subsystems of the apparatus, wherein non-essential subsystems are shut off or driven in a power saving mode. For instance, said non-essential subsystems may include the further wireless interface like WLAN or short range communication (e.g. Bluetooth) or near field communication (e.g., RFID-based communication.

Furthermore, for instance, in the power saving mode the main may be at least partially or completely shut off, as explained above, or the silicon area associated with the enhanced phone application of the main processor be powered down. Thus, power reduction can be achieved due to operating the apparatus in the power saving mode in step.

According to an exemplary embodiment of an aspect of the invention, the apparatus comprises a display, and wherein said power saving mode comprises at least one of: limiting display brightness of the display, using only a part of the display area of the display, disabling a second display of the apparatus, disabling the display and using a second display of the apparatus, disabling the display and operating the apparatus via an audio interface of the apparatus. Thus, as an example, in the power saving mode a user interface may be configured to provide limited functionality in order to reduce power consumption. As an example, the user interface may comprise a display and said power saving mode comprises limiting display brightness of the display, wherein the display may represent a back illuminated display and limiting display brightness might comprise limiting or shut off back illumination of the display, play brightness of a back illuminated display. And/or, said power saving mode may comprise using only a part of the display area of the display, wherein a bigger part of the display area is used in non-power saving mode.

Furthermore, as an example, the display may be assumed as a first display, wherein the user interface may comprise a second display, and wherein the power saving mode may comprise disabling the second display of the apparatus (e.g., while simultaneously using the first display), or disabling the first display and using the second display of the apparatus. Or, as another example, the power saving mode may comprise disabling the first display (e.g., also disabling the second display) and operating the apparatus via an audio interface of the user interface of the apparatus. For instance, said operating the apparatus via an audio interface may comprise scrolling through menus using speech tags, wherein said menus for instance may comprise recent calls, wherein the speech tags may be pre-programmed when the apparatus is in the second state. Thus, said programming of speech tags may represent one functionality of the at least one extended phone functionality of the enhanced phone application. According to an exemplary embodiment of an aspect of the invention, a power state of the apparatus is detected, and the apparatus is operated in the first state or in the second state based on the detected power state.

For instance, if the apparatus is in the second state and if the detected power state indicates that power consumption should be reduced, it is determined that the apparatus is to be operated in the first state in order to reduce power consumption. For instance, a power state indicating that power consumption should be reduced might represent at least one of the following: when the voltage level of the apparatus or of an energy source (like a battery) of the apparatus is less than a predefined voltage level, when the at least one extended phone functionality is not used for a predefined time interval, and when the apparatus is operated in the second state for a predefined time interval.

If it is determined that the apparatus is to be operated in the first state, it may be proceeded with operating the apparatus in the first state. Thus, in this first state the basic phone application is provided and reduction power consumption can be achieved since the extended phone functionalities are not provided, as mentioned above. Furthermore, for instance, after the transition from the second state to the first state it may be indicated via an output interface that the apparatus now only provides the basic phone application and/or that no enhanced phone application is provided. For instance, this may be indicated on a display of the apparatus or by any other well-suited output.

For instance, if the apparatus is in the first state and if the detected power state indicates that power consumption should not be reduced anymore, it is determined that the apparatus is to be operated in the second state in order to provide full enhanced phone application functionality without reduction of power consumption. For instance, a power state indicating that power consumption should not be reduced anymore might represent at least one of the following: when the voltage level of the apparatus or of an energy source (like a battery) of the apparatus is equal or greater than the predefined voltage level, and when the apparatus is operated in the first state for a predefined time interval.

If it is determined that the apparatus is to be operated in the second state, it may be proceeded with operating the apparatus in the second state. Furthermore, for instance, after the transition from the first state to the second state it may be indicated via an output interface that the apparatus now provides the enhanced phone application. For instance, this may be indicated on a display of the apparatus or by any other well-suited output. According to an exemplary embodiment of an aspect of the invention, the apparatus is operated in the first state or operated in the second state based on a user interaction.

For instance, if the apparatus is in second state it may be detected whether there is a user interaction which indicates that the apparatus is to be operated in the first state. For instance, this user interaction may comprise any user input via an input interface of the apparatus in order to activate the first state and thus providing the basic phone application.

Or, for instance, if the apparatus is in the first state it may be detected whether there is a user interaction which indicates that the apparatus is to be operated in the second state. For instance, this user interaction may comprise any user input via an input interface of the apparatus in order to activate the second state and thus providing the enhanced phone application. Thus, as an example, a user can activate or deactivate the enhanced phone application.

According to an exemplary embodiment of an aspect of the invention, said apparatus represents a mobile phone. For instance, said mobile phone may represent a mobile phone in accordance with the 3rd Generation Partnership Project (3 GPP).

DETAILED DESCRIPTION OF EMBODIMENTS OF THE INVENTION Fig. la schematically illustrates components of an apparatus 1 according to an embodiment of the invention. Apparatus 1 may for instance be an electronic device that is for instance capable to provide phone functionalities. For instance, apparatus 1 may be or may form a part of a terminal, wherein this terminal may represent a mobile terminal.

Apparatus 1 may for instance be configured to provide either a basic phone application comprising a set of basic phone functionalities or an enhanced phone application comprising a set of enhanced phone functionalities, wherein the set of enhanced phone functionalities comprises at least one extended phone functionality compared to the set of basic phone functionalities.

Apparatus 1 may for instance be embodied as a module. Non-limiting examples of apparatus 1 are a mobile phone (e.g. a smartphone), a personal digital assistant, a portable multimedia (audio and/or video) player, and a computer (e.g. a laptop or desktop computer).

Apparatus 1 comprises at least one processor 10 (only one processor is depicted in Fig. la), which may for instance be embodied as at least one microprocessor, at least oneDigital Signal Processor (DSP) or at least one Application Specific Integrated Circuit (ASIC), to name but a few non-limiting examples. The at least one processor 10 executes program code stored in program memory 11, and uses main memory 12 as a working memory, for instance to at least temporarily store intermediate results, but also to store for instance pre-defined and/or pre-computed databases. Some or all of memories 11 and 12 may also be included into the at least one processor 10. Memories 1 1 and/or 12 may for instance be embodied as Read-Only Memory (ROM), Random Access Memory (RAM), to name but a few non-limiting examples. One of or both of memories 11 and 12 may be fixedly connected to the at least one processor 10 or removable from the at least one processor 10, for instance in the form of a memory card or stick.

The at least one processor 10 further controls an input/output (I/O) interface 13, via which the at least one processor receives or provides information to other functional units.

As will be described below, the at least one processor 10 is at least capable to execute program code for providing the any aspect of the invention. However, the at least one processor 10 may of course possess further capabilities. Processor 10 may additionally or alternatively be capable of controlling operation of a portable communication and/or multimedia device.

Apparatus 1 of Fig. la may further comprise components such as a user interface, for instance to allow a user of apparatus 1 to interact with the at least one processor 10, or an antenna with associated radio frequency (RF) circuitry to enable apparatus 1 to perform wireless commumcation. As an example, apparatus 1 may comprise one or more RF circuitry configured to perform cellular wireless communication and/or WIFI wireless communication (e.g., WLAN) and/or short range wireless communication (e.g., Bluetooth) and/or near field wireless communication (e.g., based on RFID), wherein the one or more RF circuitry may be connected to at least one antenna.

The circuitry formed by the components of apparatus 1 may be implemented in hardware alone, partially in hardware and in software, or in software only, as further described at the end of this specification. Fig. lb is a schematic illustration of an embodiment of a tangible storage medium 20 according to the invention. This tangible storage medium 20, which may in particular be a non-transitory storage medium, comprises a program 21 , which in turn comprises program code 22 (for instance a set of instructions). Realizations of tangible storage medium 20 may for instance be program memory 12 of Fig. la. Consequently, program code 22 may for instance implement the flowcharts of Figs. 2, 6 and 7 associated with an aspect of the invention discussed below.

Fig. 2 shows a flowchart 200 of a method according to a first embodiment of a first aspect of the invention. The steps of this flowchart 200 may for instance be defined by respective program code 32 of a computer program 31 that is stored on a tangible storage medium 30, as shown in Fig. lb. Tangible storage medium 30 may for instance embody program memory 11 of Fig. la, and the computer program 31 may then be executed by the at least one processor 10 of Fig. la. Fig 2 will be explained in conjunction with a schematic illustration 300 of an example embodiment of an architecture of an apparatus 300 according to an aspect of the invention depicted in Fig. 3. For instance, this apparatus 300 may represent or be based on apparatus 1 depicted in Fig. 1. It has to be understood that the order of steps 210 and 220 depicted in Fig. 2 may be exchanged, i.e. method 220 for instance may start with step 220 and the proceed with step 210.

In a step 210 the apparatus 300 is operated in a first state in which a basic phone application 310 comprising a set of basic phone functionalities is provided. For instance, the set of basic phone functionalities comprises at least one of voice call functionality, short message service functionality, and low-speed data transmission via a radio-frequency (RF) interface 340 of the apparatus 300. For instance, said low-speed data transmission may represent a circuit switched or packet switched data transmission with a data rate less than 250 kbit/s, e.g. less than 100 kbit/s or less than 50 kbit/s, wherein said low-speed data transmission for instance may represent a cellular radio transmission like a CSD or GPRS (e.g. 2.5G) or EGPRS (e.g. 2.75G) transmission or any other well-suited low-speed cellular based data transmission. Accordingly, the basic phone application 310 may be assumed to implement only basic phone functionalities and thus may be considered to represent a basic phone application engine. Furthermore, in a step 220 the apparatus is operated in a second state in which an enhanced phone application 320 comprising a set of basic phone functionalities is provided, wherein the set of enhanced phone functionalities comprises at least one extended phone functionality compared to the set of basic phone functionalities. For instance, the set of enhanced phone functionalities may comprise at least a part of the functionalities of the set of basic phone functionalities or the complete set of basic phone functionalities. Additionally, the set of enhanced phone functionalities comprises at least one extended phone functionality, wherein this at least one extended phone functionality is not part of the set of basic phone functionalities of the basic phone application 310.

As an example, the at least one extended phone functionality may comprise at least one of a high-speed data transmission via the radio frequency interface 340 of the apparatus 300, position detection, video output on a display, camera functionality, microphone functionality, applications configured to perform access to the internet, and an application configured to pre-program speech tags.

When the apparatus 300 is in the first state and thus the basic phone application 310 is provided, the enhanced phone application may be completely deactivated. Thus, as an example, the basic phone application 310 may be implemented in apparatus 300 to function as being totally independent from the enhanced phone application 320, wherein in the first state the at least one extended phone functionality may be not instantiated. Accordingly, in the first state the enhanced phone application 320 may be considered to be shut down and thus the at least one extended phone functionality may not even provided as idle functionalities when the basic phone application 310 is provided in the first state. For instance, without launching the enhanced phone application 320, the at least one extended phone functionality can not be made available and can not be provided. As an example, the enhanced phone application 320 may be realized at least partially as hardware and/or or at least partially as software, wherein the hardware part of the enhanced phone application 320 may be deactivated in the first state, and/or wherein the software part of the enhanced phone application 320 may be deactivated in the first state, e.g. by means of stopping the software part and/or closing the software part.

Thus, the apparatus 300 is not configured to provide one of the at least one extended phone functionalities when the apparatus is in the first state. The basic phone application 310 may be considered to represent an application tailored to provide only basic functionalities of a phone, as described above, wherein this basic phone application 310 may be considered or be implemented as a low complexity phone part 310 which might, for instance, be designed for minimum or minimized power consumption compared to the power consumption of the an enhanced phone application 320.

For instance, the basic phone application 310 may have access to the essential subsystems of the apparatus, wherein these essential subsystems may comprise an identification module 330, which might be configured to receive a subscriber identification module, e.g. a SIM card, and a RF interface 340, and an input/output (I/O) interface 350. For instance, the basic phone application 310 may only have limited access to the RF interface 340 and/or to the (I/O) interface 350.

As an example, the basic phone application 310 may only have access to a cellular RF interface of the RF interface 340, wherein the RF interface 340 may provide further wireless interfaces like WLAN or short range communication (e.g. Bluetooth) or near field communication (e.g., RFID-based communication) which may be not accessed may by the basic phone application 310. The short range communication may be considered to provide a shorter communication range via the air than WLAN systems, e.g. a range between 0m and 20m, preferably between 0m and 10m, or less than 10m, and the near field communication may be considered to have a shorter communication range via the air than near filed communication systems, e.g. a range between 0m and 2, preferably between 0m and lm, or less than lm. In contrast to the basic phone application 310, the enhanced phone application 320 may have complete access to all essential subsystems and may have access to at least one further subsystem of the apparatus 300, wherein this at least one further subsystem is indicated by further module(s) 360 depicted in Fig. 3.

For instance, this further module(s) 360 may comprise a module configured to detect the position of the apparatus, e.g. based on received satellite signals, wherein this module may be configured to detect the position in accordance with a GPS or

GLONASS or any other well-suited satellite based positioning system. Thus, the at least one extended phone functionality of the enhanced phone application 320 may comprise a position detection functionality which might use the mode for detecting the position of the apparatus 300. Or, as an example, the further module(s) 360 may comprise an accelerometer, wherein the at least one extended phone functionality of the enhanced phone application 320 may comprise a functionality for obtaining the speed and/or acceleration of the apparatus 300.

Accordingly, in the first state only the basic phone functionalities of the basic phone application 310 are provided which enables minimized power consumption since the at least one processor 10 of the apparatus 300 (not depicted in Fig. 3) provides the basic phone application 310 but not the enhanced phone application 320. In particular, as an example, this minimized power consumption is achieved since in this first state the at least one extended phone functionality of the enhanced phone application 320 may not be instantiated and, for instance, may not be held in the background of an operating system running on the at least one processor.

If the apparatus 300 is switched in the second state, for instance, the enhanced phone application 310 may be launched or activated and then full extended phone

functionality 310 can be provided, wherein power consumption is increased compared to the first state.

The explanations presented with respect to Fig. 3 hold for any of the following example embodiments. Fig. 4a depicts a schematic illustration of a first example embodiment of a processor architecture 400 of an apparatus according to an aspect of the invention. This apparatus may represent any of the apparatuses 1 and 300 depicted in Figs, la and 3. This first example embodiment of a processor architecture 400 comprises a main processor 421 and a secondary processor 411. For instance, both the main processor 421 and the secondary processor 411 can be switched on and of independently from each other. The main processor 421 is configured to provide the enhanced phone application 420 which may be represent or be based on the enhanced phone application 320 described with respect to Fig. 3. Accordingly, the enhanced phone application 420 may be launched on or provided by the main processor 421 in order to provide the set of enhanced phone functionalities in the second state of the apparatus. For instance, the enhanced phone application 420 may be launched and/or operated as an enhanced phone application engine 420 on the main processor 421.

Furthermore, the secondary processor 411 is configured to provide the basic phone application 410, which may represent or be based on the basic phone application 310 described with respect to Fig. 3. Accordingly, the basic phone application 410 may be launched on or provided by the secondary processor 411 in order to provide the set of basic phone functionalities in the first state of the apparatus. For instance, the basic phone application 410 may be launched and/or operated as an enhanced phone application engine 410 on the secondary processor 411.

Furthermore, for instance, when the apparatus is in first state, the main processor 421 is configured not to provide the enhanced phone application. As an example, in the first state the enhanced phone application 420 may be completely (or at least partially) deactivated on the main processor 421, wherein this deactivating for instance may comprise stopping the enhanced phone application engine on the main processor 421 , or removing the enhanced phone application engine on the main processor 421, or deinstalling the enhanced phone application from the main processor 421, or at least partially switching of the main processor 421, e.g., switching of a silicon area of the main processor being associated with the enhanced phone application, or completely switching off the main processor. For instance, these explanations may also hold for the main processor 410' depicted in Fig. 4b.

The basic phone application 410 can be operated independently from the enhanced phone application 420 due to the use of the secondary processor 411. As an example, the secondary processor 411 may represent a low power processor 411 compared to the main processor 412, wherein the secondary processor 411 may for instance be implemented in low power silicon technology compared to the silicon technology of the main processor 421 , and/or wherein the secondary processor may be operated at a lower clock frequency and/or lower voltage compared to the main processor 412. For instance, these explanations may also hold for the secondary processor 41 1 ' depicted in Fig. 4b.

When the apparatus is operated in the second state, for instance, the secondary processor may be switched of or the basic phone application 410 running on the secondary processor 411 may be deactivated, wherein this deactivating for instance may comprise stopping the basic phone application engine 410 on the secondary processor 411, or removing the basic phone application engine 410 on the secondary processor 41 1, or deinstalling the basic phone application from the secondary processor 41 1.

Fig. 4b depicts a schematic illustration of a second example embodiment of a processor architecture 400' for an apparatus according to an aspect of the invention. This apparatus may represent any of the apparatuses 1 and 300 depicted in Figs, la and 3.

This second example embodiment of a processor architecture 400' comprises a main processor 42 Γ and a secondary processor 41 Γ. For instance, both the main processor 421 and the secondary processor 411 can be switched on and off independently from each other.

The main processor 421 is configured to provide at least the at least one extended phone functionality of the enhanced phone application 420' which may be represent or be based on the at least one extended phone functionality of the enhanced phone application 320 described with respect to Fig. 3. Accordingly, at least a part of the set of enlianced phone functionalities, i.e., at least the extended phone functionality, can be provided by the main processor 421 '. Furthermore, the secondary processor 411 ' is configured to provide the basic phone application 410', which may represent or be based on the basic phone application 310 described with respect to Fig. 3. Accordingly, the basic phone application 410' may be launched on or provided by the secondary processor 41 1 ' in order to provide the set of basic phone functionalities in the first state of the apparatus. For instance, the basic phone application 410' may be launched and/or operated as an enhanced phone application engine 410' on the secondary processor 41 Γ.

When the apparatus is in the second state and thus the enlianced phone application is provided, the enhanced phone application might be provided by the main processor 421 ' in conjunction with the secondary processor 411 ', wherein the at least one extended phone functionality of the enhanced phone application 420' is provided by the main processor 421 ', and wherein the enhanced phone application uses at least one functionality of the set of basic phone functionalities provided by the basic phone application provided by the secondary processor 410', as indicated by reference sign 425 in Fig. 4b. Thus, those functionalities of the set of enhanced phone functionalities which also represent functionalities of the set of basic phone functionalities must not be necessarily be provided by the main processor 421 ' in the second state, since the enhanced phone application may use these functionalities provided by the secondary processor 411 '. Thus, with respect to this second example embodiment of a processor architecture 400' depicted in Fig. 4b, the secondary processor 410' is not switched off in the second state of the apparatus, but the enhanced phone application uses at least one of the functionalities of the set of basic phone functionalities of the basic phone application 410' provided by the secondary processor 41 Γ. Furthermore, for instance, when the apparatus is in first state, the main processor 421 ' is configured not to provide the enhanced phone application, as explained with respect to the first example embodiment of a processor architecture 400 depicted in Fig. 4a. Fig. 5a depicts a schematic illustration of a third example embodiment of a processor architecture for an apparatus in a first state according to an aspect of the invention. This apparatus may represent any of the apparatuses 1 and 300 depicted in Figs, la and 3. The processor architecture 500 comprises a processor 530 which is configured to provide the basic phone application 510, as depicted in Fig. 5a, wherein the basis phone application 510 may represent any of the above described basis phone applications 310, 410, 410', when the apparatus is in this first state. Accordingly, in the first state the processor 530 does not provide the enhanced phone application.

In the second state, the processor 530 is configured to provide the enhanced phone application 520, as depicted in Fig. 5b, wherein the enhanced phone application 520 which may represent any of the above described enhanced phone applications 320 and 420.

For instance, as a first example, when the apparatus operated in the first state and is then operated in second state, during the transition process from the first state to the second state the basic phone application 510 may be deactivated on the processor 530, wherein this deactivating may comprise stopping the basic phone application and/or cancelling the basic phone application, or switching of a silicon area of processor 530 associated with the basic phone application, and the enhanced phone application 520 may be launched and then run on the processor 520. Furthermore, for instance, during the transition process from the second state to the first state the enhanced phone application 520 is deactivated on the processor 530, wherein this deactivating may comprise stopping the enhanced phone application 520 and/or cancelling the basic phone application 520, or switching of a silicon area of the processor 530 associated with the enhanced phone application 530, wherein for instance this silicon area associated with the enhanced phone application 520 at least partially or completely differs from the silicon area associated with the basic phone application 510, and the basic phone application 510 may be launched and then run on the processor 520 when the apparatus is in the first state.

Or, for instance, as second example, in the second state the basic phone application may be considered to represent a part of the enhanced phone application 520, and during the transition process from the first state to the second state the basic phone application 510 the at least one extended phone functionality of the enhanced phone application 520 is launched, wherein the at least one extended phone functionality and the basis phone application 510 and may be considered to represent the activated or instantiated enhanced phone application 520, wherein the basis phone application 510 may still provide the set of phone basis functionalities in the second state. Furthermore, for instance, during the transition process from the second state to the first state the enhanced phone application 520 is deactivated on the processor 530, wherein this deactivating may comprise stopping the at least one extended phone functionality and/or cancelling the at least one extended phone functionality such that remaining application corresponds to the basic phase application 510. For instance, said deactivating the enhanced phone application 520 may comprise switching of a silicon area of the processor 530 associated with the at least one extended phone functionality of the enhanced phone application 520, wherein for instance this silicon area associated with the at least one extended phone functionality of the enhanced phone application 520 at least partially or completely differs from a silicon area associated with the basic phone application 510.

Fig. 6 depicts a flowchart of a second example embodiment of a method 600 according to an aspect of the invention. For instance, this method 600 may be used for any of the above described apparatuses 1 , 300 and any of the described processor architectures 400, 400', 500, and, this method 600 may be based on the method 200 depicted in Fig 2.

For instance, without any limitation, it may be assumed that the method starts at step 610 by operating the apparatus in the second state. As another example, the method 600 may start by operating the apparatus in the first state.

When operating the apparatus in the second state in step 610 the apparatus provides the enhanced phone application 320, as explained above. Thus, step 610 may comprise step 220 of method 220 depicted in Fig. 2.

Accordingly, in the second state the full functionality of the enhanced phone application is available to a user. In step 620 it is checked whether the apparatus is to be operated in the first state. Furthermore, for instance, step 620 may comprise indicating via an output interface that the apparatus provides the enhanced phone application 320. For instance, this may be indicated on a display of the apparatus or by any other well-suited output.

For instance, this checking 620 may comprise detecting a power state of the apparatus, and if the detected power state indicates that power consumption should be reduced, it is determined in step 620 that the apparatus is to be operated in the first state in order to reduce power consumption. For instance, a power state indicating that power consumption should be reduced might represent at least one of the following: when the voltage level of the apparatus or of an energy source (like a battery) of the apparatus is less than a predefined voltage level, when the at least one extended phone functionality is not used for a predefined time interval, and when the apparatus is operated in the second state for a predefined time interval.

Or, for instance, this checking 620 may comprise detecting whether there is a user interaction which indicates that the apparatus is to be operated in the first state. For instance, this user interaction may comprise any user input via an input interface of the apparatus in order to activate the first state and thus providing the basic phone application.

If it is determined in step 620 that the apparatus is to be operated in the first state, the method 600 proceeds at step 630 with operating the apparatus in the first state, wherein this step 630 may comprise step 210 of method 200 in Fig. 2. Thus, in this first state the basic phone application 310 is provided and reduction power consumption can be achieved since the extended phone functionalities are not provided, as mentioned above.

Furthermore, for instance, step 630 may comprise indicating via an output interface that the apparatus only provides the basic phone application 310 and/or that no enhanced phone application 320 is provided. For instance, this may be indicated on a display of the apparatus or by any other well-suited output.

In step 630 it is checked whether the apparatus is to be operated in the second state. For instance, this checking 630 may comprise detecting a power state of the apparatus, and if the detected power state indicates that power consumption should not be reduced anymore, it is determined in step 630 that the apparatus is to be operated in the second state in order to provide full enhanced phone application functionality without reduction of power consumption. For instance, a power state indicating that power consumption should not be reduced anymore might represent at least one of the following: when the voltage level of the apparatus or of an energy source (like a battery) of the apparatus is equal or greater than the predefined voltage level, and when the apparatus is operated in the first state for a predefined time interval.

Or, for instance, this checking 630 may comprise detecting whether there is a user interaction which indicates that the apparatus is to be operated in the second state. For instance, this user interaction may comprise any user input via an input interface of the apparatus in order to activate the second state and thus providing the enhanced phone application. Thus, as an example, a user can activate or deactivate the enhanced phone application.

If it is determined in step 630 that the apparatus is to be operated in the second state, the method 600 proceeds at step 610 with operating the apparatus in the second state and the method may proceed at step 610 as explained above.

Thus, as an example, the method 600 may comprise detecting a power state of the apparatus in step 610 and/or step 630, and operating the apparatus in the first state in step 620 or in the second state in step 640 based on the detected power state.

And/or, as an example, the method 600 may comprise detecting a user interaction in step 610 and/or step 630, and operating the apparatus in the first state in step 620 or in the second state in step 640 based on the detected user interaction.

Fig. 7 depicts a flowchart of a third example embodiment of a method 700 according to an aspect of the invention. For instance, this method 700 may be used for any of the above described apparatuses 1, 300 and any of the described processor architectures 400, 400', 500, and, this method 600 may be based on the method 200 depicted in Fig 2 and/or based on the method 600 depicted in Fig. 6.

For instance, without any limitation, it may be assumed that the method 700 starts at reference sign 705, wherein it is assumed that the apparatus is in the second state and thus the enhanced phone application 320 is provided. As another example, the method 700 may start at reference sign 725, wherein it is assumed that the apparatus is in the first state. When the apparatus is or was operated in the second state, it is checked in step 710 whether the apparatus is now in first state. If yes, the method 700 proceeds at step 720 for operating the apparatus in power saving mode.

For instance, in this power saving mode the basic phone application 310 may only have access to the essential subsystems of the apparatus, wherein non-essential subsystems are shut off or driven in a power saving mode. For instance, said non-essential subsystems may include the further wireless interface like WLAN or short range communication (e.g. Bluetooth) or near field communication (e.g., RFID-based communication, as mentioned with respect to Figs. 2 and 3, and or the at least one further module 360.

Furthermore, in the power saving mode the I/O interface 350 may be configured to provide limited functionality in order to reduce power consumption. As an example, the I/O interface 350 may comprise a display and said power saving mode comprises limiting display brightness of the display, wherein the display may represent a back illuminated display and limiting display brightness might comprise limiting or shut off back illumination of the display, play brightness of a back illuminated display. And/or, said power saving mode may comprise using only a part of the display area of the display, wherein a bigger part of the display area is used in non-power saving mode.

Furthermore, as an example, the display may be assumed as a first display, wherein the I/O interface 350 may comprise a second display, and wherein the power saving mode may comprise disabling the second display of the apparatus (e.g., while simultaneously using the first display), or disabling the first display and using the second display of the apparatus.

Or, as another example, the power saving mode may comprise disabling the first display (e.g., also disabling the second display) and operating the apparatus via an audio interface of the I/O interface 350 of the apparatus. For instance, said operating the apparatus via an audio interface may comprise scrolling through menus using speech tags, wherein said menus for instance may comprise recent calls, wherein the speech tags may be pre-programmed when the apparatus is in the second state. Thus, said programming of speech tags may represent one functionality of the at least one extended phone functionality of the enhanced phone application 320.

Furthermore, for instance, in the power saving mode in step 720 the main processor 421, 42 Γ depicted in Figs. 4a and 4b may be at least partially or completely shut off, as explained with respect to Figs. 4a and 4a, or, the silicon area associated with the enhanced phone application of the main processor 530 depicted in Figs. 5a and 5b may be powered down, as explained with respect to Figs. 4a and 4b.

Thus, power reduction can be achieved due to operating the apparatus in the power saving mode in step 720.

In step 730 it is checked whether the apparatus is now in the second state. If yes, the method proceeds with deactivating the power saving mode. Thus, at least one or all of the actions taken in step 720 for operating the apparatus in the power saving mode may be reversed. Thus, for instance, it may be ensured that the enhanced phone application 320 which is now running in accordance with the second state of the apparatus has access even to non-essential subsystems of the apparatus and/or to the at least one further module and to all I/O interface 350. Then, the method 700 may proceed with checking whether the apparatus is now in the first state in step 710, and the method 700 may proceed as mentioned above.

Furthermore, for instance, the step 720 of method 700 depicted in Fig. 7 may be inserted in method 600 depicted in Fig. 6 between step 620 and step 640, e.g., operating the apparatus in the first state as indicated by step 630 in Fig. 6 may comprise operating the apparatus in power saving mode as explained with respect to step 720 in Fig. 7, i.e., step 630 in Fig. 6 may comprise step 720 of Fig. 7.
