In general, the ubiquitous computing environment refers to an environment in which a desired service can be provided by accessing a network anytime and anywhere. In order to provide various services in such a ubiquitous environment, collaboration between all computing devices in the surrounding space providing individual services is a prerequisite.

Objects in ubiquitous computing are connected to the Internet access point (NAP) through NFC (Near Field Communication) based on short-range wireless communication, and based on non-IP based simultaneous (real-time) short-range wireless communication interface. Used for networking. Based on this networking, future ubiquitous computing requires a ubiquitous smart space (USS) that allows computer systems to reconfigure computing environments "anywhere, anytime".

The ubiquitous intelligent space places a plurality of ubiquitous terminal devices in the environment, and the terminal devices provide timely and autonomous cooperation with each other in a ubiquitous intelligent space.

However, conventional ubiquitous terminal devices have different device environments (eg, device capabilities). Accordingly, when a user wants to receive a service using one terminal device, the service can be provided only in the device environment of the terminal device.

That is, in the conventional ubiquitous computing environment, a service is provided to a user by using a terminal environment held by each terminal device, so that the user runs a plurality of applications executed in the device environment of a plurality of terminal devices existing in the ubiquitous computing environment. There was a problem that could not be used.

The shared resource management server 100 may include a resource storage unit 110, a resource management unit 120, and a user area 130.

The resource storage unit 110 may store a plurality of shared resource information transmitted from each of the plurality of user terminal devices 200_1, 200_2,... 200_N connected through the network 150.

The resource manager 120 may include a sharing controller 121, a plug and play (PnP) controller 123, and a path manager 125. The path manager 125 may include a path controller 126 and an address controller 128.

The sharing control unit 121 may extract one or more pieces of shared resource information required from among a plurality of shared resource information stored in the resource storage unit 110 according to a service request of the user.

The sharing control unit 121 may communicate with one terminal device among a plurality of terminal devices 200_1, 200_2,... 200_N, for example, one terminal device for which a user requests a service, using the extracted one or more shared resource information. You can create your own virtual machine.

In addition, the sharing control unit 121 may compare the amount of shared resource information extracted according to the service request of the user with the amount of request resources required to perform the service request of the user.

The sharing control unit 121 may provide the extracted shared resource information to the user's terminal device according to the comparison result, or perform a transformation for dividing or integrating the extracted shared resource information.

For example, if the requested resource amount according to the user's request is equal to or greater than the extracted shared resource information, the sharing controller 121 may create one user virtual machine using the extracted shared resource information.

The generated one user virtual machine may be allocated with the extracted shared resource information while communicating with one terminal device for which a service is requested from the user, and perform the user's service request.

In addition, if the amount of the requested resource according to the user's request is less than the extracted amount of shared resource information, the sharing control unit 121 may perform the conversion to split the extracted shared resource information.

The division of the extracted shared resource information may be performed by the sharing controller 121, and a single user virtual machine may be generated using the divided shared resource information according to the execution result.

The generated one user virtual machine may perform a service request of the user by using the divided shared resource information while communicating with one terminal device for which a service is requested from the user.

For example, when the amount of the extracted shared resource information is 3 and the minimum division unit is a natural number 1, if the requested resource amount according to the service request of the user is 1.5, the extracted shared resource information has an amount of 1 each according to the minimum division unit. It can be divided into three shared resource information.

Accordingly, the sharing control unit 121 may generate a user virtual machine by combining two pieces of the divided three pieces of shared resource information, and allocate the divided shared resource information to the user virtual machine.
