20080316941 | METHOD AND APPARATUS FOR PROVIDING DYNAMICALLY CHANGED UPNP DESCRIPTION - Provided is a method, medium and apparatus for providing a dynamically changed universal plug and play (UPnP) description. The method includes sensing a change of a service configuration of a device complying with a predetermined standard, updating a description including information about a service based on the change of the service configuration, and advertising that the description is updated. Thus, the service configuration is matched with the description and a control point can correctly control the device whose service configuration is changed. | 12-25-2008 |
20080320177 | METHOD AND APPARATUS FOR MANAGING RESOURCES OF A UNIVERSAL PLUG AND PLAY DEVICE BASED ON A CONNECTION STATUS OF A CONTROL POINT - Provided are a method and apparatus for managing resources of a Universal Plug and Play (UPnP) device based on a connection status of a control point. The method of managing resources of a controlled device includes: monitoring an invocation of an action representing a connection of a control point for a predetermined time; determining whether the control point is connected to the controlled device or not by considering whether the monitored action is invoked or not; and increasing available resources by selectively deactivating an application which is controlled by the control point according to the determination result. Accordingly, the resources of the UPnP device can be effectively managed. | 12-25-2008 |
20090018677 | UPNP CONTROL POINT AND METHOD OF HANDLING UPNP CONTROL REQUEST - Provided is a technique for preventing a loss by storing a universal plug and play (UPnP) control request and delaying handling of the UPnP control request. A method of handling a UPnP control request in a UPnP control point includes storing a UPnP control request that is not handled in the UPnP control point, receiving a message informing that a UPnP control device has participated in a network from the UPnP control device, receiving information about capability of the UPnP control device from the UPnP control device, determining whether the UPnP control device can perform the UPnP control request that is not handled based on the information about capability of the UPnP control device, and transmitting the UPnP control request to the UPnP control device that is determined to be able to perform the UPnP control request. | 01-15-2009 |
20090031396 | METHOD OF AND APPARATUS FOR MANAGING ACCESS PRIVILEGES IN CLDC OSGi ENVIRONMENT - Provided are a method and apparatus for managing resource access privileges of an application in a Connected Limited Device Configuration (CLDC) Open Service Gateway Initiative (OSGi) environment. The method includes executing the application in a thread having a unique thread identifier, identifying the application by mapping the unique thread identifier with an application identifier from a mapping table, examining a security policy to determine the kind of resource access privileges the identified application has, and allowing or not allowing, according to the examination result, the application to access the resources. Accordingly, when an application tries to access resources in a device, access privileges of the application can be managed so that the application does not maliciously access the resources. | 01-29-2009 |
20090031402 | METHOD AND APPARATUS FOR MANAGING ACCESS PRIVILEGE IN CLDC OSGI ENVIRONMENT - Provided are a method and apparatus for managing an access privilege of an application in a Connected Limited Device Configuration (CLDC) and Open Service Gateway initiative (OSGi) environment. The method includes: marking a privileged code in the application; executing the privileged code in a secured thread having a unique thread identifier; identifying the privilege code by mapping the unique thread identifier with an application identifier from a mapping table; checking a permission policy file to determine what kind of resource access privilege the identified privileged code has; and permitting the application to access the resources according to the determination results. Accordingly, when an application tries to access resources in a framework, an access privilege of the application can be managed so that no applications can maliciously access the resources by identifying the application by using the mapping table and checking the security policy file of the identified application. | 01-29-2009 |
20090193148 | METHOD OF CREATING MASHUP APPLICATION - Provided is a method of creating a mashup application in a host device in communication with a peer device by sharing remote services. The method includes discovering a second device that uses a middleware remote service sharing mechanism within a network, wherein a mashup framework of a first device performs the discovering; analyzing functionalities of the first device and the second device, and determining one of the first device and the second device as a host device and the other of the first device and the second device as the peer device; transmitting a list of available mashup combinations to the host device, wherein the peer device performs the transmitting; and selecting a mashup combination that is to be formed from the list, wherein the host device performs the selecting. | 07-30-2009 |

20080320469 | METHOD OF RECEIVING/TRANSMITTING EVENT MESSAGE, CONTROLLED DEVICE, AND CONTROL POINT - A selective event message receiving method is provided, in which an application is installed in a controlled device (CD) by using a network, a start message which includes a parameter specifying at least one service included in the application and requests a start of the application is transmitted to the CD, and an event message that represents a state change of the at least one service specified by the parameter is received from the CD. Accordingly, the application can be efficiently managed by selectively recognizing state changes of some services of interest from among the services included in the application. | 12-25-2008 |
20080320491 | METHOD OF RECEIVING/TRANSMITTING EVENT MESSAGE, CONTROLLED DEVICE, AND CONTROLLED POINT - An event message transmitting method performed in a controlled device (CD) which is controlled by a control point (CP) is provided, in which an application is received from the CP via a network according to a network protocol, the received application is installed according to a framework of an execution environment of the CD, a first event message that represents a state change of the application is generated according to the framework, and the first event message is converted into a second event message that conforms to the predetermined network protocol. Accordingly, information about a state change of a CD which operates in an execution environment can be adaptively transmitted according to a network protocol. | 12-25-2008 |
