Method and apparatus for notifying remote user interface client about event of remote user interface server in home network

Abstract

An event notifying method includes determining whether a current home network, which is currently connected to a remote user interface server (RUIS) in a home network, is a user's home network selected by a user so as to be allowed to be notified of the event, selectively providing an event page to a remote user interface client (RUIC) selected by a user in the user's home network, and performing user authentication prior to providing the event page, thereby ensuring security of the user's private information.

1 . A method of notifying a remote user interface client (RUIC) about an event occurring in a remote user interface server (RUIS) in a home network, which is performed in the RUIS, the method comprising:
 performing authentication with respect to a remote user interface client (RUIC);   determining whether the RUIS is authorized to display the event based on a result of the authentication; and   selectively transmitting an event page indicating content of the event, based on a result of the determination, to the RUIC.   
   
   
       2 . The method of  claim 1 , wherein the performing the authentication comprises:
 transmitting an event notification message in which a uniform resource locator (URL) of an event page is replaced with a URL of an authentication page;   receiving authentication information input by the user through an HTTP POST command from the authentication page; and   determining whether the authentication is successful based on the authentication information.   
   
   
       3 . The method of  claim 1 , wherein the performing the authentication comprises:
 transmitting an HTTP 401 Login Required message in response to an HTTP GET command with respect to the event page;   receiving authentication information input by the user from the RUIC through the HTTP GET command of the authentication window; and   determining whether the authentication is successful, using the authentication information.   
   
   
       4 . A computer readable recording medium having recorded thereon a program for causing a computer to execute the method of  claim 1 . 
   
   
       5 . An apparatus for notifying a remote user interface client (RUIC) about an event in a remote user interface server (RUIS) in a home network, the apparatus comprising:
 an authentication performing unit that performs authentication with respect to a remote user interface client (RUIC) and determines whether the RUIC is authorized to display the event; and   an event page providing unit that selectively transmits an event page indicating content of the event, based on a result of the determining, to the RUIC.   
   
   
       6 . The apparatus of  claim 5 , wherein the authentication performing unit comprises:
 an event notification unit that transmits an event notification message in which a uniform resource locator (URL) of an event page is replaced with a URL of an authentication page;   an authentication information receiving unit that receives authentication information input by a user through an HTTP POST command from the authentication page; and   a determining unit that determines whether the authentication is successful based on the authentication information.   
   
   
       7 . The apparatus of  claim 5 , wherein the authentication performing unit comprises:
 an authentication information receiving unit that transmits an HTTP 401 Login Required message in response to an HTTP GET command with respect to the event page and receives authentication information input by a user from the RUIC through the HTTP GET command of an authentication window displayed in response to the transmitting; and   a determining unit that determines whether the authentication is successful based on the authentication information.   
   
   
       8 . A method of notifying a remote user interface client (RUIC) an event occurring in a remote user interface server (RUIS), which is performed by the RUIS, the method comprising:
 determining whether a current home network that is currently connected to the RUIS is a selected home network that is allowed to be notified about the event; and   selectively transmitting an event page indicating the event to at least one remote user interface client (RUIC) belonging to the current home network based on a result of the determining.   
   
   
       9 . The method of  claim 8 , wherein the determining comprises:
 determining whether at least one selected device discovered in the selected home network is discovered in the current home network; and   determining whether the current home network is the selected home network based on a result of the determining whether at least one selected device discovered in the selected home network is discovered in the current home network.   
   
   
       10 . The method of  claim 8 , wherein the transmitting comprises
 transmitting the event page to at least one RUIC that is previously selected by a user's input, in one of a unicast and a multicast method.   
   
   
       11 . A computer readable recording medium having recorded thereon a program for causing a computer to execute the method of  claim 8 . 
   
   
       12 . An apparatus for notifying a remote user interface client (RUIC) about an event in a remote user interface server (RUIS), the apparatus comprising:
 an estimation unit that determines whether a current home network that is currently connected to the RUIS is a selected home network that is allowed to be notified about the event; and   an event page providing unit that selectively transmits an event page indicating the event to at least one remote user interface client (RUIC) belonging to the current home network, based on a result of the determining.   
   
   
       13 . The apparatus of  claim 12 , wherein the estimation unit determines whether at least one selected device discovered in the selected home network is discovered in the current home network and determines whether the current home network is the selected home network based on a result of the determining whether at least one selected device discovered in the selected home network is discovered in the current home network. 
   
   
       14 . The apparatus of  claim 12 , wherein the event page providing unit transmits the event page to at least one RUIC that is previously selected by a user's input, in one of a unicast and a multicast method.
