Abstract:
A system and a method for input tool invocation and a proxy device enable an installable operating system to perform input operation by invoking the input tool of a local operating system, such as a soft keyboard of the local operating system, an input method of the local operating system, or a soft keyboard and an input method of the local operating system. Even an operating system not installed with input tools can perform input operation by invoking an input tool of a local operating system, thereby avoiding repeated installations of input tools for different operating systems, and resolving the issue of large resource usage caused by repetitive installations of input tools.

     FIELD 
     The present invention relates to the field of communications and particularly to an input tool invocation method and system and a proxy device. 
     BACKGROUND 
     Along with constant development of operating systems, the operating systems have become an indispensable software environment for predominant smart terminals, and also integrating of operating systems is increasingly stepping into the field of smart terminal operating systems, that is, a plurality of operating systems may exist concurrently on one smart terminal. For the operating systems integrated in the smart terminal, the respective operating systems themselves are separate, so soft keyboards and input methods have to be installed separately for the respective operating systems, and in order to make an input, the respective soft keyboards and input methods have to be selected and started for the different operating systems to make the input. 
     The following problems exist when a plurality of operating systems are installed in a smart terminal: 
     1. If there is no corresponding soft keyboard and input method installed in an operating system, then an input operation can not be performed in the course of running the operating system. 
     2. In order to ensure availability of each operating system, a soft keyboard and an input method have to be installed for each operating system, thus having a considerable space of the terminal occupied by the repeatedly installed soft keyboards and word bases of the input methods. 
     SUMMARY 
     Embodiments of the invention provide an input tool invocation method and system and a proxy device so as to address the problems in the prior art of failing to perform an input operation when there is no corresponding input tool installed in an operating system and of having a considerable system space occupied by repeatedly installed input tools.

     an installable operating system configured to initiate an input request; 
     a proxy module configured to trigger an local operating system upon reception of the input request and judgment of no available input tool in the installable operating system; and 
     the local operating system configured to start its own input tool as triggered by the proxy module. 
     An input tool invocation method includes: 
     judging whether there is an available input tool an installable operating system upon reception of an input request of the installable operating system; and 
     instructing a local operating system to start and display its own input tool when it is judged that there is no available input tool iii the installable operating system. 
     A proxy device includes: 
     a management unit configured to receive an input request of an installable operating system and to judge whether there is an available input tool in the installable operating system; and

     The embodiments of the invention provide an input tool invocation system and method and a proxy device so that an installable operating system can invoke an input tool of a local operating system to perform an input operation. With the solutions according to the invention, even an operating system without any input tool installed therein can perform an input operation by invoking an input tool of the local operating system to thereby avoid the problem of having a considerable system resource occupied by repeatedly installed input tools for different operating systems.

     DETAILED DESCRIPTION OF THE EMBODIMENTS 
     In view of the numerous problems arising from the impossibility to share an input tool between different operating systems, embodiments of the invention enable an input tool to be shared between a local operating system and an installable operating system. The input tool includes a soft keyboard and/or an input method so that it is not necessary to install a soft keyboard and an input method separately for the installable operating system, but an input is made by invoking a soft keyboard and an input method of the local operating system, thus avoiding the problem of an inconvenient user operation due to switching of the soft keyboard and the input method due to switching between the operating systems and also addressing the problem of having a considerable space of a terminal occupied by the soft keyboards and word bases of the input methods due to repeated installation of the soft keyboards and the input methods, which may have a system resource wasted. The local operating system refers to an operating system built in a terminal device shipped from a factory, and the installable operating system refers to an operating system that can be subsequently selected and installed by a user onto the terminal. 
     Technical solutions of the invention be described below in details with reference to the drawings and respective embodiments. 
     First Embodiment 
     The first embodiment of the invention provides an input tool invocation system, and  FIG. 1  illustrates a schematic structural diagram of the system including an installable operating system  01 , a proxy module  02  and a local operating system  03 , where: 
     The installable operating system  01  is configured to initiate an input request; the proxy module  02  is configured to trigger the local operating system upon reception of the input request and judgment of no available input tool in the installable operating system; and the local operating system  03  is configured to start its own input tool as triggered by the proxy module. 
     The input tool includes a soft keyboard and/or an input method. 
     The proxy module  02  includes a management unit  021 , a pseudo operation unit  022  and a proxy unit  023 , where:

     The pseudo operation unit  022  is further configured to apply the received data o the installable operating system over the established channel. 
     Second Embodiment 
     The second embodiment of the invention provides an input tool invocation method, and  FIG. 2  illustrates a flow chart of the method particularly including the following steps: 
     The step  001  is to judge whether there is an available input tool in an installable operating system upon reception of an input request of the installable operating system. 
     In this step, whether there is an available input tool in the installable operating system can be judged by referring to a list of software installations in the installable operating system or otherwise. For example, if an installation record of soft keyboard and/or input method software is entered in the list of software installations in the installable operating system, then it can be judged that there is an available input tool in the installable operating system; otherwise, it can be judged that there is no available input tool in the installable operating system. 
     If there is an available input tool in the installable operating system, then the input tool is used, and the invocation process of this second embodiment is terminated. And if there is no available input tool in the installable operating system, the flow proceeds to the step  002 . The input tool includes a soft keyboard and/or an input method. 
     The step  002  is to instruct a local operating system to start its own input tool if it is judged that there is no available input tool in the installable operating system. 
     When instructing the local operating system to start its own input tool, detection of an input through the input tool of the local operating system is started, and a channel is established, where the channel is configured to apply received data, input through the input tool of the local operating system, to the installable operating system. 
     The local operating system starts its own input tool in response to the received instruction and returns an input tool start success message, and if the local operating system fails to start its own input tool, then it returns an input tool start failure message and terminates the invocation process of this second embodiment. 
     The step  003  is to apply data, input through the input tool of the local operating system, into the installable operating system over the established channel upon detection of the data. 
     The input tool invocation system and method according to the first embodiment and the second embodiment of the invention will be described below in details respectively in a third embodiment and a fourth embodiment taking as an example an input tool which is a soft keyboard. 
     Third Embodiment 
     The third embodiment of the invention provides a soft keyboard invocation system, and as illustrated in  FIG. 3 , the soft keyboard invocation system includes an installable operating system  11 , a proxy module  12  and a local operating system  13 , where: 
     The installable operating system  11  is configured to initiate an input request; the proxy module  12  is configured to trigger the local operating system upon reception of the input request and judgment of no available soft keyboard in the installable operating system; and the local operating system  13  is configured to start and display its own soft keyboard as triggered by the proxy module. 
     The proxy module  12  includes a soft keyboard management unit  121 , a pseudo soft keyboard unit  122  and a soft keyboard proxy unit  123 , where: 
     The soft keyboard management unit  121  is configured to request for establishing a channel upon reception of the input request and judgment of no available soft keyboard in the installable operating system, where the channel is configured to apply data, input through the soft keyboard of the local operating system, to the installable operating system upon reception of the data; the pseudo soft keyboard unit  122  is configured to establish the channel upon reception of the request for establishing the channel from the soft keyboard management unit and to request for starting detection of an input through the soft keyboard of the local operating system; and the soft keyboard proxy unit  123  is configured to perform the detection upon reception of the request for starting the detection from the pseudo soft keyboard unit and trigger the local operating system. 
     The soft keyboard proxy unit  123  is further configured to forward data, input through the soft keyboard of the local operating system, to the pseudo soft keyboard unit upon detection of the data. 
     The pseudo soft keyboard unit  122  is further configured to apply the received data to the installable operating system over the established channel. 
     Fourth Embodiment 
     The fourth embodiment of the invention provides a soft keyboard invocation method, and  FIG. 4  illustrates a flow chart of the method of invoking a soft keyboard of a local operating system in an installable operating system, which particularly includes the following steps: 
     The step  101  is to judge whether there is an available soft keyboard in an installable operating system upon reception of an input request of the installable operating system. 
     When a user is performing an input operation in the installable operating system on a terminal, the installable operating system sends the input request to a proxy module, and the proxy module judges whether there is an available soft keyboard in the installable operating system, and if there is an available soft keyboard in the installable operating system, then it invokes the soft keyboard of the installable operating system and terminates the flow of invoking a soft keyboard of a local operating system; otherwise, the flow proceeds to the step  102 . 
     The step  102  is to instruct a local operating system to start and display its own soft keyboard if it is judged that there is no available soft keyboard in the installable operating system. 
     When it is judged that it is necessary to invoke the soft keyboard of the local operating system for the installable operating system, the proxy module instructs the local operating system to start and display its own soft keyboard on the installable operating system. And in this step, detection of an input through the soft keyboard of the local operating system is started, so that data input through the soft keyboard of the local operating system can be received subsequently, and a channel is established to apply input data to the installable operating system upon reception of the data, so that the data input subsequently into the installable operating system through the soft keyboard of the local operating system can be applied into the installable operating system. 
     The local operating system starts and displays its own soft keyboard in response to the instruction of the proxy module and returns a soft keyboard display success message to notify the proxy module and the installable operating system that the soft keyboard has been displayed successfully and that a subsequent operation can be performed. 
     The step  103  is to apply data, input through the soft keyboard of the local operating system, into the installable operating system over the established channel upon detection of the data. 
     Upon reception of the soft keyboard display success message of the local operating system, an input can be made in the installable operating system through the soft keyboard of the local operating system, and with the detection of an input performed and the channel established in the step  102 , data input through the soft keyboard of the local operating system is received, and the received data is applied into the installable operating system. 
     In the soft keyboard invocation method, an input can be made through the soft keyboard regardless of whether there is an available input method in the installable operating system When there is no available input method in the installable operating system, the installable operating system can receive data input through the soft keyboard of the local operating system in the soft keyboard invocation method according to this embodiment; and when there is an available input method in the installable operating system, the installable operating system can receive data input through the soft keyboard of the local operating system and with the available input method, in the soft keyboard invocation method according to this embodiment. 
     The step  101  and the step  102  perform a process of starting the soft keyboard of the local operating system, and the step  103  can be regarded as a process of using the soft keyboard of the local operating system. A soft keyboard starting method according to this fourth embodiment will be described below in details in connection with the respective modules and units in the soft keyboard invocation system according to the third embodiment.  FIG. 5  illustrates a communication process between the local operating system, the installable operating system and the respective modules and units in the proxy module in the process of starting the soft keyboard of the local operating system, that is, in the step  101  to the step  102 , and the communication process particularly includes: 
     In the first step, the installable operating system initiates an input request to the soft keyboard management unit. 
     The user runs the installable operating system on the terminal, and to make an input, the installable operating system initiates the input request to the soft keyboard management unit of the proxy module. 
     In the second step, the soft keyboard management unit requests the pseudo soft keyboard unit to start the soft keyboard of the local operating system. 
     The soft keyboard management unit judges whether there is an available soft keyboard in the installable operating system upon reception of the input request initiated by the installable operating system, and if there is an available soft keyboard, then it requests for popping up the available soft keyboard; otherwise, it judges that it is necessary to invoke the soft keyboard of the local operating system for the installable operating system, and since the pseudo soft keyboard unit of the proxy module is responsible for firstly integrating the soft keyboard of the local operating system with the soft keyboard of the installable operating system before the soft keyboard of the local operating system is used so that an operation performed subsequently through the soft keyboard of the local operating system can be applied to the installable operating system, the soft keyboard management unit sends the request to start the soft keyboard of the local operating system to the pseudo soft keyboard unit to instruct the pseudo soft keyboard unit to integrate the soft keyboards of the installable operating system and the local operating system. 
     In the third step, the pseudo soft keyboard unit sends an Internet Process Connection (IPC) request to the soft keyboard proxy unit. 
     With the integration done, the pseudo soft keyboard unit sends the IPC request to the soft keyboard proxy unit to notify the soft keyboard proxy unit that the installable operating system will invoke the soft keyboard of the local operating system. The soft keyboard proxy unit interfaces the soft keyboard of the local operating system to the soft keyboard of the installable operating system upon reception of the IPC request sent from the pseudo soft keyboard unit so that the installable operating system can subsequently receive an operation performed through the soft keyboard of the local operating system. 
     In the fourth step, the soft keyboard proxy unit instructs the local operating system to start and display the soft keyboard of the local operating system. 
     With the interfacing done, the soft keyboard proxy unit instructs the local operating system to start and display the soft keyboard for use by the installable operating system. 
     In the fifth step, the local operating system starts and displays the soft keyboard and returns a soft keyboard display success message to the soft keyboard proxy unit. 
     With its own soft keyboard started and displayed, the local operating system returns the soft keyboard display success message to the soft keyboard proxy unit to notify the soft keyboard proxy unit of successful interfacing of the soft keyboard of the local operating system to that of the installable operating system. 
     In the sixth step, the soft keyboard proxy unit returns the received soft keyboard display success message to the pseudo soft keyboard unit. 
     This step is for the purpose of notifying the pseudo soft keyboard unit of successful integration of the local operating system with the installable operating system. 
     In the seventh step, the pseudo soft keyboard unit returns the received soft keyboard display success message to the soft keyboard management unit. 
     This step is for the purpose of notifying the soft keyboard management unit that the installable operating system can invoke the soft keyboard of the local operating system. 
     In the eighth step, the soft keyboard management unit returns the received soft keyboard display success message to the installable operating system. 
     This step is for the purpose of notifying the installable operating system that a simple operation can be performed through the displayed soft keyboard or an input operation can be performed through the soft keyboard of the local operating system and an available input method according to the received soft keyboard display success message. 
     The input tool invocation system and method according to the first embodiment and the second embodiment of the invention will be described below in details respectively in a fifth embodiment and a sixth embodiment taking as an example an input tool which is an input method. 
     Fifth Embodiment

     The installable operating system  21  is configured to initiate an input request; the proxy module  22  is configured to trigger the local operating system upon reception of the input request and judgment of no available input method in the installable operating system; and the local operating system  23  is configured to start its own input method as triggered by the proxy module. 
     The local operating system  23  is further configured to start the input method after setting operating parameters of the input method as triggered by the proxy module. 
     The proxy module  22  includes an input method management unit  221 , a pseudo input method unit  222  and an input method proxy unit  223 , where: 
     The input method management unit  221  is configured to request for establishing a channel upon reception of the input request and judgment of no available input method in the installable operating system, where the channel is configured to apply data, input through the input method of the local operating system, to the installable operating system upon reception of the data; the pseudo input method unit  222  is configured to establish the channel upon reception of the request for establishing the channel from the input method management unit, to generate a data input interface and to request for starting detection of an input in the interface through the input method of the local operating system; and the input method proxy unit  223  is configured to perform the detection upon reception of the request for starting the detection from the pseudo input method unit and trigger the local operating system. 
     The input method proxy unit  223  is further configured to forward data, input in the interface through the input method of the local operating system, to the pseudo input method unit upon detection of the data. 
     The pseudo input method unit  222  is further configured to apply the received data to the installable operating system over the established channel. 
     Sixth Embodiment 
     The sixth embodiment of the invention provides an input method invocation method, and  FIG. 7  illustrates a flow chart of the method of invoking an input method of a local operating system in an installable operating system, which particularly includes the following steps: 
     The step  201  is to judge whether there is an available input method in an installable operating system upon reception of an input request from the installable operating system. 
     Similarly to the first embodiment, the proxy module firstly judges whether there is an available input method in the installable operating system upon reception of the input request from the installable operating system, and if there is an available input method, then it invokes the input method of the installable operating system and terminates the flow of invoking an input method of a local operating system; otherwise, the flow proceeds to the step  202 . 
     The step  202  is to instruct a local operating system to start its own input method if it is judged that there is no available input method in the installable operating system. 
     When it is judged that it is necessary to invoke the input method of the local operating system for the installable operating system, the proxy module instructs the local operating system to start its own input method. In the course of starting the input method, the proxy module generates and displays an data input interface in the installable operating system and starts detection of an input in the interface through the input method of the local operating system, so that data input in the interface through the input method of the local operating system can be received subsequently, and a channel is established to apply input data to the installable operating system upon reception of the data, so that the data input subsequently in the interface through the input method of the local operating system can be applied into the installable operating system. 
     The local operating system sets its own input method upon reception of the instruction to start its own input method, where the setting refers to setting of various operating parameters of the input method, e.g., installation, uninstalling, a switching order, etc., of various input methods, with its own input method set, it starts its own input method and returns an input method start success message to notify the proxy module and the installable operating system that the input method has been started successfully and that a subsequent operation can be performed. 
     The step  203  is to apply data, input in the interface through the input method of the local operating system, into the installable operating system over the established channel upon detection of the data. 
     Upon reception of the input method start success message from the local operating system, an input can be made in the pop-up interface in the installable operating system through the input method of the local operating system, and with the detection of an input performed and the channel established in the step  202 , data input through the input method of the local operating system is received, and the received data is applied into the installable operating system. 
     The step  201  and the step  202  perform a process of starting the input method of the local operating system, and the step  203  can be regarded as a process of using the input method of the local operating system. An input method starting method according to this sixth embodiment will be described below in details in connection with the respective modules and units in the input method invocation system according to the fifth embodiment.  FIG. 8  illustrates a communication process between the local operating system, the installable operating system and the respective modules and units in the proxy module in the process of starting the input method of the local operating system, that is, in the step  201  to the step  202 , and the communication process particularly includes: 
     In the first step, the installable operating system initiates an input request to the input method management unit. 
     The user runs the installable operating system on the terminal, and to make an input, the installable operating system initiates the input request to the input method management unit of the proxy module. 
     In the second step, the input method management unit requests the pseudo input method unit to start the input method of the local operating system. 
     Integration of the input method of the local operating system with the input method of the installable operating system is performed in the pseudo input method unit of the proxy module, so the input method management unit requests the pseudo input method unit to start the input method of the local operating system upon reception of the input request initiated by the installable operating system and judgment of no an available input method in the installable operating system, and the pseudo input method unit integrates the input method of the local operating system with that of the installable operating system upon reception of the request from the input method management unit, so that contents input through the input method of the local operating system can be subsequently applied to the installable operating system. 
     In the third step, the pseudo input method unit requests the input method proxy unit to start the input method of the local operating system. 
     With the integration done, the pseudo input method unit requests the input method proxy unit to start the input method of the local operating system. The input method proxy unit interfaces the input method of the local operating system to the input method of the installable operating system upon reception of the request so that the installable operating system can subsequently receive contents input through the input method of the local operating system. 
     It shall be noted that the input method proxy unit pops up an operation interface in the installable operating system upon reception of the request, and each subsequent input through the input method of the local operating system is made in this operation interface. 
     In the fourth step, the input method proxy unit instructs the local operating system to start the input method of the local operating system. 
     With the interfacing done, the input method proxy unit instructs the local operating system to start the input method for use by the installable operating system. 
     In the fifth step, the local operating system starts its own input method and returns an input method start completion message to the input method proxy unit. 
     Before the input method is started, a relevant setting operation of the input method will be made, e.g., setting of installation, uninstalling, a switching order, etc., so with its own input method set, the local operating system starts its own input method and returns the input method start completion message to the input method proxy unit to notify the input method proxy unit of successful interfacing of the input method of the local operating system to that of the installable operating system. 
     In the sixth step, the input method proxy unit returns the received input method start completion message to the pseudo input method unit. 
     This step is for the purpose of notifying the pseudo input method unit of successful integration of the input method of the local operating system with that of the installable operating system. 
     In the seventh step, the pseudo input method unit returns the received input method start completion message to the input method management unit. 
     This step is for the purpose of notifying the input method management unit that the input method of the local operating system has been started successfully and that the installable operating system can invoke the input method of the local operating system. 
     In the eighth step, the input method management unit returns the received input method start completion message to the installable operating system. 
     This step is for the purpose of notifying the installable operating system that an input can be made through the input method of the local operating system. After the input method start completion message is sent to the installable operating system, the pop-up interface can be used in the installable operating system to perform an input operation in the interface. 
     The input tool invocation system and method according to the first embodiment and the second method of the invention will be described below in details respectively in a seventh embodiment and an eighth embodiment taking as an example an input tool which is a soft keyboard and an input method. 
     The soft keyboard invocation system and the input method invocation system according to the third embodiment and the fifth embodiment of the invention can separately enable a soft keyboard to be shared and an input method to be shared respectively between an installable operating system and a local operating system, and the systems according to the third embodiment and the fifth embodiment of the invention can also be integrated into one system so that both a soft keyboard of a local operating system and an input method of the local operating system can be invoked in an installable operating system, and a system for enabling a soft keyboard and an input method to be shared between a local operating system and an installable operating system according to a seventh embodiment will be described below in details.

     Eighth Embodiment 
     The eighth embodiment of the invention provides a soft keyboard and input method invocation method, and  FIG. 10  illustrates a flow of a data input method according to this embodiment, which particularly includes: 
     The step  301  is to judge whether there are an available soft keyboard and an available input method in an installable operating system upon reception of an input request from the installable operating system. 
     When a user is performing an input operation on a terminal, the installable operating system sends the input request to a proxy module, and the proxy module judges whether there are an available soft keyboard and input method in the installable operating system, and if there are an available soft keyboard and input method, then it invokes the soft keyboard and the input method of the installable operating system and terminates the flow of invoking a soft keyboard and an input method of a local operating system; otherwise, the flow proceeds to the step  302 . 
     The step  302  is to instruct a local operating system to start and display its own soft keyboard and to start its own input method if it is judged that there is neither available soft keyboard nor available input method in the installable operating system. 
     When it is judged that it is necessary to invoke the soft keyboard and the input method of the local operating system for the installable operating system, the proxy module instructs respectively the local operating system to start and display its own soft keyboard on the installable operating system and the local operating system to start its own input method. 
     In the course of instructing the local operating system to start and display its own soft keyboard, the proxy module starts detection of an input through the soft keyboard of the local operating system; and in the course of instructing the local operating system to start its own input method, the proxy module generates and displays an data input interface in the installable operating system and starts detection of an input in the interface through the input method of the local operating system. 
     In the meanwhile of instructing the local operating system to start and display its own soft keyboard and to start the input method, the proxy module establishes channels configured to apply input data to the installable operating system upon detection of the data, where the channels include the following two channels: 
     The first channel is established to apply an input through the soft keyboard and the input method of the local operating system to the installable operating system upon detection of the data through the soft keyboard; and the second channel is established to apply an input the interface through the input method and the soft keyboard of the local operating system to the installable operating system upon detection of the data through the input method. 
     The local operating system starts and displays its own soft keyboard and starts its own input method and returns a soft keyboard display success message and an input method start success message to notify the proxy module and the installable operating system that an input operation can be performed. 
     The step  303  is to apply data, input through the input method and the soft keyboard of the local operating system, into the installable operating system over the established channels upon detection of the data. 
     The proxy module can apply an input through the soft keyboard and the input method of the local operating system to the installable operating system over the established first channel upon detection of the data through the soft keyboard and can also apply an input in the interface through the input method and the soft keyboard of the local operating system to the installable operating system over the established second channel upon detection of the data through the input method, that is, the proxy module can select either of the detection methods and the corresponding channel to apply the detected input data to the installable operating system. 
     The step  301  and the step  302  perform a process of starting the soft keyboard and the input method of the local operating system, and the step  303  can be regarded as a process of using the soft keyboard and the input method of the local operating system. The input management unit in the seventh embodiment can be equivalent respectively to the soft keyboard management unit in the third embodiment and the input method management unit in the fifth embodiment, and the other units than the input management unit in the proxy module can also be regarded as units with the same functions as the corresponding units in the third embodiment and the fifth embodiment, so the respective modules and units in the seventh embodiment of the invention perform the method of starting a soft keyboard and an input method of a local operating system according to the eighth embodiment of the invention in the same communication process between the respective modules and units as the communication processes between the respective modules and units according to the fourth embodiment and the sixth embodiment, and a repeated description will be omitted here. 
     The first channel and the second channel iii the seventh embodiment and the eighth embodiment may not necessarily be established concurrently, that is, the proxy module can establish only the first channel while instructing the local operating system to start and display its own soft keyboard and to start the input method and subsequently apply received data to the installable operating system over the established first channel; or can establish only the second channel while instructing the local operating system to start and display its own soft keyboard and to start the input method and subsequently apply received data to the installable operating system over the established second channel; or establish both the first channel and the second channel while sending the instruction and subsequently select either of the channels to apply received data to the installable operating system.
