Description

Method of executing services on devices}

The present invention relates to a method of executing a service in a device. More particularly, when a service is to be executed in a device and does not support a required task in the device, the service execution method performs a task using a nearby device. It is about.

Today's mobile devices are becoming smaller, higher in performance and supporting a variety of features. As a result, it's easy to see how many mobile devices you can carry with you. Using multiple devices means that the number of memories to be managed increases, and as memory technology advances, management becomes more difficult as the storage space gets larger.

If there are tasks required to run a service on the current device, you need to install the necessary components and test them to see if they work properly before you can use them. For example, to use the navigation service, you need to connect the GPS and install the device driver. If any of the required tasks are not installed on the device, user intervention is required.

Therefore, if you want to expand a service or use a new service on a device you have, you must install it manually by user intervention when resources or specific tasks such as specific hardware are required. In this case, the user must know what tasks are required for the new service, or the user will be restricted from using them.

SUMMARY OF THE INVENTION The present invention provides a method and a method of executing a service in a device capable of performing a task using a peripheral device when a device does not support a task required by the device when a service is to be executed. A computer readable recording medium having recorded thereon a program for execution is provided.

In order to solve the above technical problem, a service execution method in a device according to the present invention includes: (a) identifying tasks required for a service in a service execution device to execute a service; searching for a device supporting the task among devices around the service execution device when there is a task not supported by the service execution device among the identified tasks; (c) performing the task in the found device and transmitting the result of the task to the service execution device; And (d) receiving a result of performing the task from the searched device to complete a service.

Here, the service execution device and the peripheral devices preferably have a task specification including information on tasks required for a service and tasks supported by the service execution device. In this case, the information about the task may include information about the name, type, data type, and performance of each task.

In addition, step (b) may check whether there is a task that is not supported by the service execution device by referring to the task specification.

In addition, step (b) may include: (b1) transmitting a task search signal including information about the task to devices around the service execution device; (b2) confirming whether a device which has received the task search signal can perform the task with reference to a task specification that the device has received based on information included in the task search signal; And (b3) transmitting a task search response signal to the service execution device when the task can be performed.

Here, the task search signal may be transmitted by a broadcasting method, and the response signal may be transmitted by a unicast method.

The step (c) may further include transmitting a task request signal including information about the task from the service execution device to the retrieved device; And performing a task in the searched device that has received the task request signal, and transmitting a task request response signal including the data generated as a result to the service execution device.

The method may further include receiving a selection of which device to perform the task from a user through a user interface of the service execution device when a plurality of devices supporting the task are found in step (b). It may further include.

In this case, based on the information about the performance of the task received from the searched device in the step of receiving the selection can recommend a device having a better performance to the user.

In order to solve the above technical problem, there is provided a computer-readable recording medium having recorded thereon a program for executing a service execution method in a device according to the present invention.

According to the present invention described above, even when the device does not support a required task when a service is to be executed in a device, a nearby device may be searched for and performed without the user's intervention. Therefore, users do not need to install hardware or software necessary for new services every day, and can flexibly cope with new devices with their own devices.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings. In the following description and the accompanying drawings, substantially the same components are denoted by the same reference numerals, and redundant description will be omitted. In addition, in the following description of the present invention, if it is determined that a detailed description of a related known function or configuration may unnecessarily obscure the subject matter of the present invention, the detailed description thereof will be omitted.

1 is a flowchart illustrating a service execution method in a device according to an embodiment of the present invention. In the present embodiment, a device for which a user executes a service will be referred to as a service execution device. The devices described in this embodiment may be mobile devices that are movable, connected to each other via a wireless network, and devices may communicate with each other using a wireless communication means such as wireless Internet, and may be grouped through a network. Can be.

When the user instructs the execution of a specific service in the service execution device (step 110), the service execution device checks tasks required for the service (step 115). In the present embodiment, the service execution device and the surrounding devices are all information about services provided by the service and the tasks required for each service, the name and type of the task supported by the service, and the data type (input / output data, processing data). Etc.) and a task specification including information on the performance of the task. The service execution device checks the tasks required for the service to be executed by referring to this task specification.

If necessary tasks are identified, the service execution device checks whether any of the identified tasks are not supported by itself (step 120). To this end, the service execution device refers to information on a task supported by the service execution device. At this time, if there are no unsupported tasks, that is, if all tasks required for the service are included in supporting tasks in the task specification, the process proceeds to step 122 and performs all the identified tasks.

If there is an unsupported task, that is, if one of the tasks required for the service is not included in the supporting tasks in the task specification, the process proceeds to steps 125 and 130 to be described later.

In the description of this embodiment, it is assumed that the service to be executed requires three tasks (hereinafter, first to third tasks), and the service execution device supports the first and third tasks but does not support the second task. Shall be. That is, the second task is not included in the tasks supported by the second task on the task specification of the service execution device.

If it is determined in step 120 that the second task is not supported among the tasks required for the service, the process proceeds to step 125 to perform the first task, and at the same time (or after performing the first task), devices around the service execution device. Among the devices, a device supporting the second task is searched for in operation 130.

If a device supporting the second task is found among the neighboring devices, the service execution device requests the performed device to perform the second task (step 135). At this time, the service execution device transmits, as a task request signal, data necessary for the execution of the second task (for example, result data of the first task if necessary), information on the required output data format, and the like to the searched device.

The device receiving the task request signal performs the second task (step 140), and transmits the task execution result to the service execution device (step 145). At this time, the data generated as a result of task execution is transmitted together.

The service execution device receives the second task execution result from the found device (step 150), and if there is no error in the result data, the service execution device finishes the service by performing the third task (step 155).

FIG. 2 is a flowchart illustrating a specific embodiment of a process of searching for a device supporting a specific task in the vicinity, that is, step 130 described above.

As shown, the service execution device transmits a task search signal including information on a request to request, for example, the name and type of the task, a data type, and the like to the surroundings using a broadcasting scheme.

The peripheral device receiving the task search signal checks whether the requested task can be performed based on the information included in the task search signal. The device also has a task specification as described above, and checks whether the task can be performed by referring to this. If the task can be performed, the task search response signal is transmitted to the service request mobile device as a signal indicating the unicast method. The task search response signal includes information on the data type and performance of the task that can be performed based on the information included in the task specification.

The service request mobile device that receives the task search response signal refers to the received task search response signal to determine whether the device is suitable for performing a task required for service. Meanwhile, as shown, the task search response signal may be transmitted from a plurality of devices, and the service execution device checks whether the device for which the task search response signal is sent is suitable for performing the task.

3 is a flowchart for describing in more detail the steps 135 to 150 described above. The service execution device transmits a task request signal including information about a task to request to the found device in a unicast manner. If necessary, the task request signal may include data necessary to perform the task to be requested.

Upon receiving the task request signal, the found device performs a task by referring to information about a task included therein and temporarily stores the task execution result data generated as a result. The task request response signal including the stored task execution result data is transmitted to the service execution device in a unicast manner. The service execution device receives the task request response signal, stores the task execution result data included therein, and checks whether the task execution result data is generated as requested by the task request signal.

4 is a flowchart illustrating a service execution method in a device according to another embodiment of the present invention. This embodiment is an example of a case where there are a plurality of searched mobile devices, and is substantially the same as that described with reference to FIG. 1 except that steps 132 and 133 described later are added.

When a plurality of devices supporting a task required for a service are found in step 130, the searched devices are displayed through the user interface of the service execution device so that the user can know (step 132). Receive a selection (step 133). In operation 135, the selected device performs a corresponding task.

Meanwhile, in the present embodiment, the searched devices may be displayed to the user, and the task performance of each device may be compared based on the information on the task performance received from them, and the task of the device showing the better performance may be recommended. . In addition, since the camera photographing task or the RFID input / output task is directly related to the user, it is preferable to give the user a choice of which device task to use. However, in the case of a task for a certain operation such as a DMB reception task or a GPS task, even if a task of a plurality of devices is searched, it may be arbitrarily determined without a user's selection.

In addition, in the above-described embodiments, even if the task is supported by the service execution device, the device supporting the task is searched among the peripheral devices, and the task performance of the service execution device is compared with the task performance of other devices in the vicinity. If the task performance of the device is better, the task may be implemented to perform on the retrieved device instead of executing on the service execution device.

The present invention described above can be applied to, for example, the following cases.

If the service that the user has commanded execution through the service execution device is a service that recognizes the image code, the necessary tasks may be a camera photographing task and a task of recognizing the code from the photographed image. In this case, the service execution device has an image code recognition application, but there is no camera. When the camera shooting task is not supported, the camera execution task is requested by searching for the device that has the camera among the peripheral devices when the camera shooting task is required during service execution. As a result, it receives the captured image as data and recognizes the image code therefrom.

Alternatively, to use the navigation service, only the navigation program is executed on a device that does not have GPS installed. If a GPS task is required, the device searches for a device that has GPS among the peripheral devices, and is connected to the device to perform a GPS task. You can run

According to the present invention described above, it is possible to retrieve and use a task required for the service from the peripheral devices without the need for additional installation of hardware or software. Therefore, it will be possible to flexibly cope with the devices that are currently present for the newly emerging service.

Meanwhile, the above-described embodiments of the present invention can be written as a program that can be executed in a computer, and can be implemented in a general-purpose digital computer that operates the program using a computer-readable recording medium. The computer-readable recording medium may include a magnetic storage medium (eg, ROM, floppy disk, hard disk, etc.), an optical reading medium (eg, CD-ROM, DVD, etc.) and a carrier wave (eg, internet). Storage medium).

So far I looked at the center of the preferred embodiment for the present invention. Those skilled in the art will appreciate that the present invention can be implemented in a modified form without departing from the essential features of the present invention. Therefore, the disclosed embodiments should be considered in an illustrative rather than a restrictive sense.
