Control method and system in a communication system

The present invention relates to a method and apparatus for providing application service in a mobile communication system. A method in which a base station provides application service comprises: a step of receiving a request for application service from a mobile terminal; and a step of providing the mobile terminal with the requested application service on the basis of application service information pre-stored in the base station and/or application service information received from an application server, in accordance with whether or not the application service information corresponding to the requested application service is pre-stored in the base station.

Method and apparatus for providing application service in a mobile communication system

Methods and apparatuses are provided for providing an internet service by a server in a communication system. A user interface for selecting whether to provide a search service based on location information of a subscriber station, is provided to the subscriber station. If the subscriber station selects to be provided the search service based on the location information, the location information of the subscriber station is acquired using a location information server or a cell identifier (ID) according to an existence of the location information server in the communication system. Data is sought based on the location information. The data is provided to the subscriber station.

Method and apparatus for providing internet service based on user's location information in a communication system

A method and system for providing a phone directory service to a user terminal in a mobile communication network are provided. The method includes displaying, when a search keyword for the phone directory service is input by a user, a business list including businesses corresponding to the search keyword on a screen of the user terminal, connecting a call connection with a business selected by the user among the businesses displayed on the screen, displaying at least one product image provided by the selected business on the screen during the call connection, displaying, if a desired product is selected by the user, order details for the selected product during the call connection, processing payment of the selected product during the call connection, and displaying details for the payment on the screen.

Method and system for providing phone directory service for mobile communication subscriber

A system is disclosed for providing a bell to a call-terminating terminal that includes a call-originating terminal for generating at least one group, setting group list information which includes additional services usable by the generated group and predetermined terminals belonging to the generated group, registering the set group list information, and transmitting a call request to a terminal belonging to the group; a first server for receiving the call request from the call-originating at a midway point of a route of the call request, acquiring the group list information registered by the call-originating terminal, constructing an additional service menu in accordance with the acquired group list information, and providing the constructed additional service menu through a bell; and the call-terminating terminal for receiving information of the additional service menu constructed by the first server, and constructing an additional service menu usable by the call-originating terminal based on the information.

Method and system for providing multimedia portal contents and additional service in a communication system

A method and system for providing a phone directory service to a user terminal in a mobile communication network are provided. The method includes receiving a search request including a search keyword for the phone directory service and a subscriber identifier for the user terminal from the user terminal, acquiring subscriber information of a subscriber possessing the user terminal from the mobile communication network in which the user terminal is registered using the subscriber identifier, acquiring a business list of businesses corresponding to the search keyword from a business DataBase (DB) for managing businesses which have subscribed to the phone directory service, arranging the business list based on a communication pattern of a group of similar subscribers which have been determined to have subscriber information similar to that of the subscriber possessing the user terminal according to a predetermined criteria, and providing the arranged business list to the user terminal.

A method for providing an Internet service based on location information of a subscriber station in a communication system. The Internet service method includes, upon receipt of a search request from a subscriber station, determining whether a network accessed by the subscriber station can support a Universal Service Interface (USI), acquiring location information of the subscriber station if the network accessed by the subscriber station can support the USI, and providing an Internet service based on the acquired location information of the subscriber station to the subscriber station.

A power control method by a mobile station (MS) in a communication system. In the power control method, the MS receives data while activating a first communication module for performing a wireless communication by supplying power to the first communication module, and performs data transmission/reception with an MS-assistant device interacting with the MS, if the received data is voice data.

A base station includes a center frequency setting unit, a local oscillator, a baseband processor, and an RF processor. In the event of a frequency band change, the center frequency setting unit sets a center frequency of a use frequency channel to have a predetermined offset value with respect to a center frequency before the frequency band change. The local oscillator generates an LO frequency signal according to the center frequency set by the center frequency setting unit. The baseband processor generates a downlink baseband signal. The RF processor uses the LO frequency signal to convert the downlink baseband signal into an RF signal prior to transmission.

Apparatus and method for supporting frequency rearrangement in wireless communication system

A system and method provide calling and called terminals with multimedia alerting signals such as a ringtone and ringback tone. When desiring to receive first multimedia portal contents as a multimedia alerting signal, the calling terminal presets the first multimedia portal contents and makes a call connection setup request. When desiring to provide second multimedia portal contents as a ringback tone, a called terminal presets the second multimedia portal contents and notifies that the ringtone and ringback tone are set. A Personal Internet Protocol Multimedia Subsystem (IMS) Portal (PIP) server receives call connection setup-related signals from the calling and called terminals, decides to provide particular multimedia portal contents as the ringback tone according to a predefined priority decision criterion when the calling and called terminals set the multimedia portal contents, and provides the set multimedia portal contents.
