The evaluation of the correspondence indicator value replaces some application set up actions, such as navigation through a menu structure of the electric device, otherwise being required from the user. As a result, the application set up is simplified.

List of drawings [0014] In the following, the invention will be described in greater detail with reference to the preferred embodiments and the accompanying drawings, in which [0015] Figure 1 shows a first example of a system of electric devices; [0016] Figure 2 shows a second example of a system of electric devices; [0017] Figure 3 shows an example of an electric device; [0018] Figure 4 illustrates a first example of a methodology according to embodiments of the invention; and [0019] Figure 5 illustrates a second example of a methodology according to embodiments of the invention.

Description of embodiments [0020] With reference to Figure 1 , in an aspect, a system includes an electric device (ED#1 ) 100, also referred to as "a first electric device". The electric device 100 is associated with another electric device (ED#2) 102, also referred to as "a second electric device". [0021] In another aspect of the invention, the system includes an electric device 102, also referred to as "a second electric device". The electric device 102 is associated with another electric device 100, also referred to as "a first electric device". [0022] The first electric device 100 and the second electric device 102 include a first user application (APPL#1 ) 104 and a second user application (APPL#2) 106, respectively. The first user application 104 and the second user application 1O6 use shared application data 112, which are communicated between the first electric device 100 and the second electric device 102 by using a wireless interface 108. [0023] For the ease of discussion, let a common term "a user application" represent the first user application 104 and/or the second user application 106. Furthermore, let a common term "a set of information" represent a first set of information 114 and/or a second set of information 116. In addition, let a term "electric device" represent the first electric device 100 and the second electric device 102. The use of the common terms is justified on the basis of common features included in the first electric device 100 and the second electric device 102. However, features specifically related to the first electric device 100 and the second electric device 102, respectively, are indicated with the attributes "the first" and " the second". [0024] The electric device 100,102 may be a handheld gaming console. The electric device 100,102 may further include a mobile phone radio modem, thus enabling the electric device 100, 102 to connect to a telecommunications infrastructure. In such a case, the electric devices 100, 102 may both be connected to a network infrastructure of a wireless telecommunications system through which the application data 112 is communicated between the first electric device 100 and the second electric device 102. The wireless telecommunications system may include a GSM (Global System for Mobile telecommunications) and/or a UMTS (Universal Mobile Telecommunications System), for example. [0025] The electric device 100, 102 may further be comprise a personal computer, a video game console, a television set, or a digital adapter connected to a television set and a broadcast system. [0026] It should be noted that the first electric device 100 and the second electric device 102 may have different characteristics. For example, the first electric device 100 may be a portable electric device equipped with a mobile phone radio modem while the second electric device 102 is a permanently mounted type device, such as a television set, a digital adapter or a video game console. [0027] In an embodiment of the invention, the first user application 104 and the second user application 106 are game applications. In such a case, the application data 1 12 deliver, for example, the necessary control information and commands from one electric device to another in order to enable interactive operation between the game applications. [0028] In an embodiment of the invention, the first user application 104 and the second user application are communication applications, which enable the first electric device 100 and the second electric device 102 to exchange data. The communication applications typically implement communication protocols and may be used, for example, to exchange files, such as elec- trie business cards, graphics files, audio files and/or text files between the first electric device 100 and the second electric device 102. [0029] The first user application 104 and the second user application 106 are associated with a first set of information (INFO#1 ) 114 and a second set of information (INFO#2) 116, respectively. At least one portion of the first set of information 114 is generated in the first electric device 100. At least one portion of the second set of information 116 is generated in the second electric device 102. [0030] At least one portion of the second set of information 116 is communicated from the second electric device 102 to the first electric 100 device over a wireless proximity interface 11 0. [0031] The wireless proximity wireless interface 110 provides a short-range wireless telecommunications link between the first electric device 100 and the second electric device 102. The range of the proximity wireless interface 110 may vary, for example, from centimeters to dozens of meters. The range is not, however, restricted to this example. [0032] The proximity wireless interface 110 may be based on radio frequency communication, such as a Bluetooth technology. Embodiments may exist which utilize RFID (Radio Frequency Identification) technology. An average skilled person is familiar with the aforementioned wireless proximity technologies, and therefore, the technologies are described only briefly. [0033] In an embodiment of the invention, the wireless interface 108 is a wireless proximity interface. In such a case, the application data 112 and the at least one portion of the second set of information 116 may be communicated over a shared wireless proximity interface 110. [0034] In the first electric device 100, a correspondence indicator value is evaluated on the basis of at least one portion of a first set of information 114 and the at least one portion of the second set of information 116. The correspondence indicator value typically characterizes the readiness of the first electric device 100 and the second electric device 102 to execute at least one command associated with the first user application 104 and the second user application 106. [0035] On the basis of the correspondence indicator value, a decision is made whether or not to execute the at least one command. If the correspondence indicator value indicates that the readiness of the electric devices 102, 104 is sufficiently high, the at least one command may be executed. If the correspondence value indicates that the readiness of the electric devices is sufficiently high, the at least one command is not executed. [0036] The at least one command associated with the first user application 104 and the second user application 106 is typically a command which gives rise to interactive actions in the first user application 104 and the second user application 106. An interactive action is typically an action performed by a computer and involves and/or is followed by communication of the application data 112. The at least one command may be associated with a series of commands, which are executed automatically by the operating system and/or by the user application 104, 106 and which correspond to the most probable actions performed by the user. As a result, the at least one command is used to replace a series of actions of the user, and so the usage of the user application 104, 106 is simplified. For example, navigation steps through a complex user interface menu structure may be replaced with the at least one command. [0037] In an embodiment of the invention, the at least one command is a start command to start the first user application 104 and the second user application 106. The start command may be generated in the first electric device 100 and delivered to the second electric device 104, embedded in the application data 112, or transmitted over the wireless proximity interface 110. In an embodiment of the invention, the at least one command starts a game application. [0038] In an embodiment of the invention, the at least one command starts the communication of the application data 112. In such a case, the first user application 104 and the second user application 106 may be running at the moment the command is executed. [0039] In an embodiment of the invention, the at least one command sets the user application 104, 106 and/or the operating systems of the electric device 100, 102 such that the user application 104, 106 is in a standby state. In a standby state, the user application 104, 106 is ready to be started. The standby state may be indicated to the user of the electric device 104, 106. The user application 104, 106 may be started based on a command generated by the user. [0040] The set of information 114, 116 is associated with the user application 104, 106. The set of information 114, 1 16 may include user application information, such as identification information and application data format information. The user application information typically describes the technical characteristics of the user application 104, 106, thus making it possible to evaluate whether the first user application 104 and the second user application 106 fulfill the technical requirements needed for an interactive operation. In such a case the correspondence indicator may characterize the readiness of the first electric device 100 and the second electric device 102 to execute commands associated with the first user application and the second user application from the point of view of the technical characteristics of the first user application 104 and the second user application 106. [0041] In an embodiment of the invention, the set of information 114, 116 may further include usage information relating to the user application 104, 106. The usage information may include user preferences and usage history of the user application 104, 106. [0042] The user preferences may include user settings relating to the user application and/or the operating system in which the user application operates. A user preference may be, for example, a degree of difficulty setting of a game application. The user preference may include a user setting, which enables or disables the user application to be executed in an interactive mode. In an interactive mode, the application data are being shared between the first electric device 100 and the second electric device 102. In such a case, the correspondence indicator value characterizes the match between the user preferences related to the first user application 104 and the second user application 106. The better the match between the first user application 104 and the second user application 106, the higher the correspondence indicator value and the readiness of the first electric device 100 and the second 102 electric device to execute the at least one command associated with the first user application 104 and the second user application 106. [0043] The usage history of the user application may include, for example, a participation rate at which the electric device 100, 102 has executed the user application 104, 106 in an interactive mode. The participation rate characterizes the probability of the user of the user application 104, 106 to be willing to participate in the interactive action. The higher participation rate for both the first user application 104 and the second user application 106, the higher the correspondence indicator value and thus the readiness of the first electric device 100 and the second 102 electric device to execute the at least one command associated with the first user application 104 and the second user application 106. [0044] In an embodiment of the invention, the set of information 114, 116 includes a readiness parameter, which characterizes the user's readiness to use the user application 104, 106. [0045] In an embodiment of the invention, the readiness parameter includes information on the selected menu item shown to the user. The selected menu item is typically a graphical indicator, which indicates to the user a selection item in a selection tree structure. In such a way, the readiness parameter indicates the user's possible preparedness to use the user application 104, 106. [0046] The selected menu item may relate to the user application 104, 106 and/or to the operating system of the electric device 100, 102. When included in the second set of information 116, for example, the readiness parameter informs the first electric device 100 that the second electric device 102 is willing to participate in an interactive session where the application data 112 are shared. If the first set of information 114 indicates the readiness of the first electric device 102 to participate an interactive session, the correspondence indicator value increases, which results in a higher probability of executing the at least one command. Finally, the at least one command may lead to an automatic configuration of the applications 104, 106 to participate in the interactive session. [0047] In an embodiment of the invention, the readiness parameter includes action information on the actions performed and/or being performed by the electric device 100, 102. The action information may characterize the current and/or previous actions performed by the user, thus indicating the activity of the user. [0048] The action information may include information on the current and/or previous actions, and possibly time information on the actions. Such actions may be, for example, navigation actions in the user menu structure, actions associated with accepting and/or initiating calls, and/or actions associated with user applications. [0049] With reference to Figure 2, the first electric device 202 includes an application unit (AU#1 ) 206 for executing commands associated with the first user application 104 of the first electric device 202. The application unit 206 may be implemented with a computer and software of the electric device 202. For example, game applications may be run in the application un it 206. [0050] The application unit 206 may be connected to an application data communication unit (ADC#1 ) 224, which provides the wireless interface 108 and communicates the application data 112 with the second electric device 204. The application data communication unit 224 may be implemented with a telecommunications system radio modem, which provides a communication link between the first electric device 202 and the network infrastructure of the wireless telecommunications system. In an embodiment of the invention, the application data communication unit 224 implements the wireless proximity interface 110. The application data communication unit 224 may input the application data 112 to the application unit 206 and receive the application data 112 outputted by the application unit 206. [0051] The first electric device 202 further includes a proximity communication unit (PXU#1 ) 208 for providing the proximity interface 110 between the first electric device 202 and the second electric device 204. The proximity communication unit 208 may include a radio modem for implementing, for example, a Bluetooth radio interface or an RFID interface. The technology to provide such a wireless proximity interface is known to one skilled in the art, and only details relevant to the present solution are referred to. It should be noted that the application communication unit 224 and the wireless proximity communication unit 208 may share resources, such as radio transmitters, memory, and processing power. In an embodiment of the invention, the application communication unit 224 is included in the proximity communication unit 208. [0052] In an embodiment of the invention, the proximity communication unit 208 requests a wireless proximity connection from a plurality of electric devices. The wireless proximity connection may scan the frequency range supported by the wireless proximity interface and transmit a wireless proximity connection request 232 to the second electric device 204. [0053] A positive acknowledgement of the request may be generated in an electric device, which has received a wireless proximity connection request 232. The proximity communication unit 208 may receive a positive acknowledgement message 234, and a procedure to establish the wireless proximity connection may be carried out on the basis of the positive acknowledgement message 234. [0054] In an embodiment of the invention, the communication of the at least one portion of the second set of information 116 from the second electric device 204 to the first electric device 202 is triggered on the basis of the positive acknowledgement. The first electric device 202 may, for example, indicate the second electric device 204 about the preparedness of receiving the second set of information 116. [0055] The wireless proximity communication unit 208 receives at least one portion of the second set of information 116 from the second electric device 204 over the wireless proximity interface 110 and delivers the second set of information 116 to a correspondence evaluating unit (CEU) 214. [0056] The first electric device 202 includes an application information register (AIR#1 ) 210 connected to the application unit 206. The application information register 210 includes the first set of information 114 of the first electric device 202. The application information register 210 may be implemented with a memory device, for example. [0057] The application i nformation register 210 may be provided with parameters, such as readiness parameters and parameters characterizing user settings of the applications from the application unit 206. In an embodiment of the invention, the application information register 210 is connected to the user interface of the first electric device 202 so that the user actions related to usage of the user applications and the menu items, for example, may be registered. [0058] The first set of information 114 is inputted from the application information register 210 to the correspondence evaluating unit 214. Fu rthermore, the second set of information 116 is inputted from the proximity communication unit 208 to the correspondence evaluating unit 214. [0059] The correspondence evaluating unit 214 evaluates the correspondence indicator value 230 and outputs the correspondence indicator value 230 to a decision unit (DU) 212 connected to the correspondence evaluating unit 214. [0060] On the basis of the correspondence indicator value 230, the decision unit 212 decides whether or not to execute the at least one command. [0061] In an embodiment of the invention, the decision unit 21 2 compares the correspondence indicator value 230 with a correspondence indicator threshold value. The correspondence indicator threshold value may be defined by the user or it may have been programmed into the memory of the first electric device 202 by a manufacturer or an operator. If the correspondence indicator value 230 exceeds the correspondence indicator threshold value, the decision unit generates instructions 236, 242 to execute the at least one command associated with the second user application 104 and the first user application 106. [0062] In an embodiment of the invention, the decision unit 232 inputs the instructions 236 to the proximity communication unit 208, which transmits the instructions 236 to the second electric device 204. The second electric device 204 may execute the at least one command on the basis of the instructions 236. [0063] In an embodiment of the invention, the decision unit 212 is connected to the application unit 206 and inputs the instructions 242 to the application unit 206. The application unit 206 executes the at least one command on the basis of the instructions 2-42. [0064] The correspondence indicator value 230 may be used to determine details of the at least one command. For example, a high value of the correspondence indicator indicates a high level of correspondence between the user preferences and the technical requirements of the electric devices 202, 204, and the command associated with the first user application 104 and the second user application 106 may replace a series of actions otherwise performed by the users. For example, if the electric devices 202, 204 are technically identical, the user applications 104, 106 are identical, and furthermore, the usage history of the electric devices 202, 204 indicating a strong desire to participate in an interactive session, the command may start the user applications automatically. If the correspondence indicator is lower, some user actions, such as confirmation of the start of the user application, may be required. [0065] The correspondence evaluating unit 214 may be implemented with the computer of the first electric device 202 and software. [0066] The decision unit 212 may be implemented with the computer of the first electric device 202 and software. [0067] With further reference to Figure 2, an aspect the invention provides the second electric device 204. [0068] The second electric device 204 includes an application unit (AU#2) 216, a proximity commu ication unit (PXU#2) 218, an application information register (AIR#2) 220, and an application data communication unit (ADC#2) 226. [0069] The application unit 215 executes commands associated with the second user application 106 of the second electric device 204. The application unit 216 may be implemented with a computer and software of the second electric device 204. For example, game applications may be run in the application unit 216. [0070] The application unit 216 ay be connected to the application data communication unit 224, which provides the wireless interface 108 and communicates the application data 112 with the first electric device 202. The application data communication unit 226 may be implemented with a telecommunications system radio modem, which provides a communication link between the second electric device 204 and the network infrastructure of the wireless telecommunications system. In an embodiment of the invention, the application data communication unit 226 i mplements the wireless proximity interface 110. The application data communication unit 226 may input the application data 112 to the application unit 216 . [0071] The proximity communication unit 218 provides the proximity interface 110 between the first electric device 202 and the second electric device 204. The proximity communication unit 218 may include a radio modem for implementing, for example, a Bluetooth radio interface or an RFID interface. The technology to provide such a wireless proximity interface is known to one skilled in the art, and only details relevant to the present solution are referred to. It should be noted that the application communication unit 226 and the wireless proximity communication unit 218 may share resources, such as radio transmitters, memory, and processing power. In an embodiment of the invention, the application communication unit 226 is included in the proximity communication unit 218. [0072] The application informatio n register 220 includes the second set of information 116 of the second electric device 204. The application information register 220 may be implemented with a memory device, for example. [0073] The application information register 210 may be provided with parameters, such as readiness parameters and parameters characterizing user settings of the applications from the application unit 216. In an embodiment of the invention, the application information register 220 is connected to the user interface of the second electric device 204 so that the user actions related to the usage of the user applications and the menu items, for example, may be registered. [0074] The application information register 220 is connected to the proximity communication unit 218 and inputs the second set of information 216 to the proximity communication unit 218. The proximity communication unit 218 transmits at least one portion of the second set of information 116 to the first electric device 202. [0075] The proximity communication unit 218 receives the instructions 236 to execute at least one command, the at least one command being associated with the second user application 106. The instructions 236 are delivered to the application unit 216, which executes the at least one command on the basis of the instructions 236. [0076] In an embodiment of the invention, the proximity communication unit 218 receives a wireless proximity connection request 232. The proximity communication unit 218 may generate a positive acknowledgement of the request and trigger the communication of the second set of information 116 to the first electric device 202 on the basis of the positive acknowledgement. The proximity communication unit 218 may further transmit a positive acknowledgement message 234 to the first electric device 202 in order to confirm that the wireless proximity connection may be established. [0077] With reference to Figure 3, an electric device 300 may include a computer 310, a memory u nit 312, a user interface 314, and a proximity communication unit 302. [0078] An application unit 206, 216, a correspondence evaluating unit 214 and a decision unit 212 may be implemented in the computer 310 by using software stored in the memory unit 312. An application information register 210, 220 may be implemented in the memory unit 312. The input/output traffic of the application information register 210, 220 may be routed via the computer. [0079] The proximity communication unit 302 typically includes an antenna 304, a transceiver 306 and a base band unit 308. The base band unit 308 may be connected to the computer 310 in order to enable signals, such as those associated with the instructions 236 and the second set of information 116 to be exchanged. [0080] With reference to Figures 4 and 5, a methodology according to embodiments of the invention is illustrated with flow charts. [0081] In Figure 4, the method starts in 400. [0082] In 402, a wireless proximity connection is requested from a plurality of electric devices. [0083] In 404, the wireless proximity connection is established between a first electric device and a second electric device 204 on the basis of a positive acknowledgement of a wireless proximity connection request 234. [0084] In 406, communication of a second set of information from the second electric device to the first electric device is triggered on the basis of the positive acknowledgement. [0085] In 408, at least one portion of the second set of information 116 is communicated from the second electric device 204 to the first electric device 202 over a wireless proximity interface 108, the second set of information 116 being associated with a second user application 106 of the second electric device 204. [0086] In 410, a correspondence indicator value 230 is evaluated on the basis of at least one portion of a first set of information 114 and the at least one portion of the second set of ϊ nformation 116. [0087] In 412, on the basis of the correspondence indicator value 230 it is decided whether to execute the at least one command. [0088] In 414, the method ends. [0089] In Figure 5, the method starts in 500. [0090] In 502, a correspondence indicator value 230 is evaluated on the basis of at least one portion of the first set of information 114 and the at least one portion of the second set of information 116. [0091] In 504, the correspondence indicator value 230 is compared with a correspondence indicator threshold value. [0092] In 506, the method divides into two cases. If the correspondence indicator value 230 does not exceed the correspondence indicator threshold value, the method ends. [0093] If the correspondence indicator value 230 exceeds the correspondence indicator threshold value, instructions 236 to execute the at least one command associated with the first user application 104 and the second user application 106 are generated in 508. [0094] In 510, the instructions 236 to execute the at least one command associated with the first user application 114 and the second user application 116 are transmitted from the first electric device 202 to the second electric device 204 over the wireless interface 108, the instructions 236 being based on a comparison between the correspondence indicator value 230 and a correspondence indicator threshold value. [0095] In 512, the instructions 236 are received in the second electric device 204. [0096] In 514, the least one command associated with the second user application 106 is executed on the basis of the instructions 236. [0097] in 516, the method ends. [0098] In an aspect, the invention provides a computer program for executing a computer process, of which embodiments are shown and described in conjunction with Figures 4 and 5. The computer program may be stored in the memory unit 312 and executed in the computer 310. [0099] The computer program may be embodied on a computer readable medium, such as a CD (Compact Disc), a hard drive, a diskette, and a portable memory unit. The computer program may further be transferred with an electric signal in a data network, such as the Internet. [0100] Even though the invention has been described above with reference to an example according to t e accompanying drawings, it is clear that the invention is not restricted thereto but it can be modified in several ways within the scope of the appended claims.
