A method of transmitting content to a content receiver and of receiving content from a content transmitted is provided. The method may include receiving, at a content transmitter, a content transmission request fragmenting a segmented content corresponding to the content transmission request into at least one frame, generating a header comprising a frame identifier for the at least one frame, and transmitting the at least one frame and the header to the content receiver.

Method and apparatus for content transmission and content reception

Disclosed is a power control method by a first device in a communication system. In the power control method, a first communication module is activated by supplying power to the first communication module without supplying power to the second communication module, data is received using the first communication module, the second communication module is activated by supplying power to the second communication module for transmitting the data to a second device using the second communication module, the data is transmitted to the second device using the second communication module, and the power supply to the second communication module is interrupted, if the data transmission is completed.

Control method and system in a communication system

A system and method for controlling congestion using Request-to-Send (RTS) and Clear-to-Send (CTS) in a wireless mesh network are provided. A receiver in a congestion state sets a duration field value of congestion control in a CTS frame and transmits the CTS frame to a sender. In response, the sender retransmits an RTS frame to the receiver without transmitting data, after waiting for an RTS retransmission waiting time period corresponding to the duration field value. The congestion state information is broadcast to neighboring nodes. Therefore, the congestion control system using the CTS frame does not use a separate frame for the congestion control. And, all of the neighboring nodes can participate in the congestion control, increasing the network efficiency.

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 of performing user authentication of a mobile station by proxy in a communication system is provided. The method includes receiving an authentication request, which requests authentication of a user, from an Internet service provider having received information indicating that the mobile station can perform authentication based on only the mobile station's own information, requesting the user to provide security identification information for authentication, receiving the security identification information input by the user, authenticating the user by determining whether the security identification information is valid information, through security-requiring information managed by the mobile station, and transmitting an authentication result to the Internet service provider and receiving an authorized authentication result from the Internet service provider and providing a service according to the authorized authentication result to the user.

Apparatus and method for performing user authentication by proxy in wireless communication system

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.

An apparatus and method for providing Short Message Service (SMS) and Multimedia Messaging Service (MMS) over a wired telephone network are provided. In an Access Point (AP), an access module provides a wireless connection interface for wireless communication with a convergence terminal. A control module controls wireless communication and communications with the wired telephone network to provide the SMS and the MMS to the convergence terminal via the access module. A wired phone module, connected to the access module and the wired telephone network, exchanges wireless communication signals with the wired telephone network. An SMS processor, connected to the access module and the wired telephone network, processes SMS transmission and reception, and an MMS processor, connected to the access module, processes MMS transmission and reception.

Apparatus and method for providing short message service and multimedia messaging service over a wired telephone network

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.

Provided is an apparatus and method for providing a cell-based advertisement broadcast service in a broadband wireless communication system. In an advertisement broadcast service of a service interface server in the broadband wireless communication system, an advertisement content transmission request message containing at least one of information about advertisement broadcast content, information about an advertisement broadcast zone, and information about an advertisement broadcast channel is received from a service provider. The received advertisement content transmission request message is transmitted to an MCBCS controller.

A media transmission method and apparatus of a first server using a session-based messaging service in a communication system. The first server sets Media Relay Capacity (MRC) information of a first User Equipment (UE), transmits the set MRC information to a second server, receives a response from the second server after transmitting the MRC information, and notifies the response to the first UE. The response is a response that the second server has received from a second UE after notifying the second UE of the setting of the MRC information.

Media transmission method and apparatus in a communication system

An apparatus and method are provided for changing network interfaces in a multiaccess mobile terminal in a wireless communication system including a server for providing high-capacity data transmission service to a mobile terminal, and the terminal for receiving data from the server and supporting various network interfaces. Upon detecting handoff based on current air information received, an interface module reports a change in interface to a new air interface to an upper layer, and manages the mobile terminal such that traffic is transmitted to the new air interface. Upon receiving information on the new air interface from the interface module, a service module determines a bandwidth of the new air interface, generates a message based on the determined bandwidth, and transmits the generated message.

Apparatus and method for changing network interfaces in a multiaccess mobile terminal
