The present invention relates to an apparatus and a method for configuring a personal space. More particularly, the present invention relates to an apparatus and a method for configuring a personal space using a virtual switch.
Today, a communication network to which devices may be connected has gradually diversified, such as a wireless sensor network (WSN), a wireless local area network (WLAN), Bluetooth, ZigBee, Wi-Fi, a 3G mobile communication, or the like. Typically, devices configuring a personal environment are vertically managed and operated according to a connection communication network. As an example, devices disposed in a predetermined space such as a ZigBee sensor node connected to the WSN, a media server connected to the WLAN, a sensor connected to a wired router, an M2M server or a personal terminal connected to the 3G mobile communication network, or the like, are vertically operated according to the connection communication network. Therefore, even though the devices according to the related art are physically disposed in a single space, the devices are operated by a network separated according to a management operator of a connection network and a core network and thus, cannot provide integrated services supporting a person.
The present invention has been made in an effort to provide an apparatus and a method for configuring a personal space that provide integrated services supporting a person by virtually integrating devices interworked with a heterogeneous communication network using a virtual switch.

The virtual switching unit may include: a device registration unit that registers the second device in a predetermined network based on the information on the second device; a device setting unit that processes a memory of the registered second device to be set as a virtual switching target device; and a switching unit that virtually switches the set second device to the first device. In addition, the device setting unit may process a stack of the registered second device.

The virtual switching unit may use a network adaptation layer for virtual switching as a layer located at the upper rank of the network layer.
The virtual switching unit may use, as the network adaptation layer, a converter layer for interworking a protocol between the first device and the second device, a translator layer for analyzing IDs and addresses of the second device, a virtual space switch layer for switching the virtual space associated with the interworking of the first device and the second device, and an application layer processing application programs associated with a user personal space configuration.
The virtual switching unit may further use, as the network adaptation layer, a virtual content switch layer for switching the virtual content to be provided to the second device from the first device and a network management layer managing a network for virtual switching.
The virtual switching unit may further include a device information collection unit that collects content information of the second device or environmental information associated with the second device as the information on the second device.
The device search unit may search the second device located within a predetermined distance from the first device or further search the device interworked with the first device and a homogeneous communication network.
Another exemplary embodiment of the present invention provides a method for configuring a personal space, including: searching at least one second device interworked with a first device and a heterogeneous communication network; virtually switching the first device and the searched second device with a virtual switch by using information on a layer located at an upper rank of a network layer; and configuring a user personal space, including the first device, the searched second device, and the virtual switch.
The virtual switching may include: registering the second device in a predetermined network based on the information on the second device; processing a memory of the registered second device to be set as a virtual switching target device; and virtually switching the set second device to the first device. In addition, the device setting unit may process a stack of the registered second device.
The configuring of the personal space may include: connecting to a network associated with a user personal space by using a switching program added to the second device at the time of performing the virtual switching; extracting application programs to be applied to the second device connected to the network in consideration of a profile for configuring the user personal space; and configuring the user personal space using the extracted application programs.
The virtual switching may use a network adaptation layer for virtual switching as a layer located at the upper rank of the network layer.
The virtual switching may use, as the network adaptation layer, a converter layer for interworking a protocol between the first device and the second device, a translator layer for analyzing IDs and addresses of the second device, a virtual space switch layer for switching the virtual space associated with the interworking of the first device and the second device, and an application layer processing application programs associated with a user personal space configuration.
The virtual switching may further use, as the network adaptation layer, a virtual content switch layer for switching the virtual content to be provided to the second device from the first device and a network management layer managing a network for virtual switching.
The virtual switching may further include collecting content information of the second device or environmental information associated with the second device as the information on the second device.
The searching of the device may search the second device located within a predetermined distance from the first device or further search the device interworked with the first device and a homogenous communication network.

The personal space service registration process (S810) is configured in detail as follows. First, the personal space platform performs the virtual network registration of the selected device (S811). Thereafter, the personal space platform performs the personal space service registration (S812). Thereafter, the virtual switch, a personal space device 1, a personal space device 2, and the like, are registered by the switch or the device through the personal space platform (S813 to S815).
The virtual network configuration process (S820) is configured in detail as follows. First, the virtual switch requests local space information to the personal space platform (S821). Then, the personal space platform performs the reply thereto (S822). Thereafter, the virtual switch requests the virtual network configuration to the first device and the second device (S823 and S825). Then, the first device and the second device reply thereto (S824 and S826). The virtual network configuration request (S823) and the virtual network configuration reply (S824) to the first device may be first performed and then, the virtual network configuration request (S825) and the virtual network configuration reply (S826) to the second device may be performed.
The personal space service configuration process (S830) is configured in detail as follows. First, the virtual switch requests the personal space application software to the personal space platform (S831). Then, the personal space platform performs the reply thereto (S832). Thereafter, the virtual switch requests the personal space application software configuration to the first device and the second device (S833 and S835). Then, the first device and the second device reply thereto (S834 and S836). The personal space application software configuration request (S833) and the personal space application software configuration reply (S834) to the first device may be first performed and then, the personal space application software configuration request (S835) and the personal space application software configuration reply (S836) to the second device may be performed.
The virtual content switching process (S840) is configured in detail as follows. First, the first device requests the personal space service information control to the virtual switch (S841). Thereafter, the virtual switch queries to the second device whether the personal space service information control is required (S842). If the second device replies that the control is required (S843), the virtual switch requests the personal space service information control to the personal space platform (S844). If the personal space platform replies thereto (S845), the virtual switch performs the personal space service information control for the first device (S846). In this case, the personal space service information control for the second device is performed together.
Next, a method for configuring a personal space of the apparatus 100 for configuring a personal space will be described.
First, at least one second device interworked with the first device and a heterogeneous communication network is searched (device search process (S500)). The device search process (S500) searches the second device that is disposed within a predetermined distance from the first device. The device search process (S500) may further search the device interworked with the first device and the homogeneous communication network.
Thereafter, the first device and the searched second device are virtually switched by the virtual switch by using the information on the layer located at the upper rank of the network layer as a layer added for interworking between the devices connecting to different communication networks (virtual switching process (S510)). Considering the above description, the virtual switching process (S510) may include the device registration process, the device setting process, and the switching process. The device registration process is a process of registering the second device in the predetermined network based on the information on the second device. The device setting process is a process that processes the memory of the registered second device to be set as the virtual switching target device. In particular, the device setting process processes a stack region of the registered second device.
The switching process is a process that virtually switches the set second device to the first device. Meanwhile, the virtual switching process (S510) may further include the device information collection process. The device information collection process is a process that collects the content information of the second device or the environmental information associated with the second device as the information on the second device. In the exemplary embodiment of the present invention, the device information collection process is performed prior to performing the device registration process.
The virtual switching process (S510) uses the network adaptation layer for the virtual switching as the layer located at the upper rank of the network layer. In detail, the virtual switching process (S510) uses, as the network adaptation layer, the converter layer for interworking a protocol between the first device and the second device, the translator layer for analyzing IDs and addresses of the second device, the virtual space switch layer for switching the virtual space associated with the interworking of the first device and the second device, and the application layer processing application programs associated with the user personal space configuration. The virtual switching process (S510) may further use, as the network adaptation layer, a virtual content switch layer for switching virtual contents to be provided from the first device to the second device and a network management layer managing the network for the virtual switching, as the network adaptation layer.
Thereafter, the user personal space is formed, including the first device, the searched second device, and the virtual switch (personal space configuration process (S520)). Considering this, the personal space configuration process (S520) may include the network connection process, the application program extraction process, and the space configuration process. The network connection process is a process that uses the switching program added to the second device at the time of performing the virtual switching to be connected to the network associated with the user personal space. The application program extraction process is a process that extracts the application programs to be applied to the second device connected to the network, in consideration of the profile for the user personal space configuration. The space configuration process is a process that uses the extracted application programs to configure the user personal space.
Next, the virtual switching network configuration will be described with reference to the exemplary embodiment of the present invention.
The second process (S610) is device registration that collects the device characteristics and the information needed to adapt the environment to register the corresponding device in the virtual switching network. The third process (S620) is virtual NWK loading that loads a stack needed for adding to the virtual switching network terminal. The fourth process (S630) is virtual NWK initialization that initially connects to virtual switching network by the virtual switching program applied to the device. The fifth process (S640) is personal APPS loading that loads additional application program for each characteristic of the device according to the personal space configuration profile.
The exemplary embodiments of the present invention relate to the apparatus and the method for configuring the personal space using the virtual switch and can build the network platform for configuring the personal space network, in particular, the radio sensor network platform.
