A mobile terminal suitable for dynamically displaying services recommended based on context-awareness includes: a notice information receiver to receive value-added service notice information regarding at least one recommended value-added service from a value-added service recommending server; a menu processor to acquire value-added service information associated with the value-added service notice information from stored value-added service information, determine menus to be displayed according to the acquired value-added service information and display the menus on a screen; and a value-added service output unit to receive, when a menu is selected from the displayed menus, a value-added service associated with the menu from an application server and output the value-added service on the screen. | 06-24-2010 |
20100161812 | METHOD AND APPARATUS FOR ADVERTISING SERVICE IN PERSONALIZED MANNER IN NEXT-GENERATION COMMUNICATION NETWORK - Provided are a method and apparatus for advertising a service in a personalized manner in a next-generation communication network. The method includes: receiving new service registration information, which indicates that a new service has been registered, from a service registration server; mapping the received new service registration information to service profiles included in pre-stored subscription information of a plurality of subscriber terminals and selecting a subscriber terminal which is related to the new service registration information; and identifying whether the selected subscriber terminal is subscribed to a new service notification event of a home subscriber server and sending advertising information of the new service, which is related to the new service registration information, to the selected subscriber terminal with reference to subscription information of the selected subscriber terminal. | 06-24-2010 |
20110119217 | APPARATUS AND METHOD FOR RECOMMENDING SERVICE - Provided are a service recommending apparatus and method. The service recommending method uses situation information, such as location information of a terminal possessed by a user and a user profile, to deduce the user's activity, predicts a service that is expected to be preferred by the user according to the user's situation, and provides the result of the prediction to the user. The location information of the terminal is acquired from a network server such as a location information server through an open API gateway. | 05-19-2011 |
