An apparatus and method are provided. The method includes receiving, at an electronic device including a first processor and a second processor, using the first processor, a connection request via a network, and refraining from transmitting the connection request from the first processor to the second processor based at least in part on a determination that the second processor is in a sleep state, and that the connection request is associated with data set as unallowable by the second processor.

Apparatus and method for filtering IP packet in mobile communication terminal

A portable apparatus comprising a touch screen for browsing information displayed on a screen of an external apparatus and a method for browsing information thereof are provided. The method includes displaying a link area included in the web page displayed on the screen of the external apparatus on the touch screen of the portable apparatus, in response to a first gesture of a user on the touch screen, magnifying the link area displayed on the touch screen, and in response to a second gesture of the user on the magnified link area transmitting information regarding displaying another web page related to the link area on the screen of the external apparatus from the portable apparatus to the external apparatus. Accordingly, users may browse information displayed on a screen of an external apparatus using a portable apparatus having a touch screen swiftly and conveniently.

Portable apparatus comprising touch screens for browsing information displayed on screen of external apparatus and method for browsing information thereof

An apparatus, method, and system for filtering an Internet Protocol (IP) packet in a mobile communication terminal are provided. The method includes receiving an IP packet from a network, determining whether the received IP packet is an IP packet unallowable by an application Central Processing Unit (CPU), and when the received IP packet is determined to be an IP packet unallowable by the application CPU, generating an IP packet indicating that the received IP packet is unallowable and transmitting the generated IP packet to the network.

A method and an apparatus for supporting a data service for Quality of Service (QoS) in a portable terminal using two different Operating Systems (OSs) are provided. The apparatus includes a QoS controller server, in an application chip, for sending a QoS control signal to a QoS controller client of a modem chip, the QoS controller client, in the modem chip, for controlling the modem chip based on the control signal received from the QoS controller server of the application chip, and a memory for providing a channel between the application chip and the modem chip.

Disclosed is an apparatus for determining transmit power of an uplink frame transmitted from a subscriber station to a base station and transmitting data in a mobile communication system in which a downlink frame, transmitted from the base station to the subscriber station, and the uplink frame are time division-duplexed (TDD). The apparatus includes a receive power measurement unit for measuring receive power of signals received from the base station; a transmit power controller for determining the transmit power of the uplink frame from the receive power measured by the receive power measurement unit and information related to receptions of an uplink frame, which is received from the base station; and a transmission radio frequency processor for performing radio processing so that the uplink frame is transmitted according to the transmit power determined by the transmit power controller.

Method and apparatus for adaptive open-loop power control in mobile communication system using TDD

Disclosed is a method for transmitting a pilot symbol from base stations (BSs) to a subscriber station (SS) in a communication system which includes the base stations located adjacent to each other, the method includes the steps of transmitting BS-identifying sub-carriers which represent sequences for identifying the base stations in a frequency domain of the pilot symbol; and transmitting PAPR (Peak to Average Power Ratio) sub-carriers which represent sequences for reducing a PAPR of the pilot symbol together with the transmission of the BS-identifying sub-carriers in the frequency domain.

Apparatus and method for transmitting/receiving pilot signal in communication system using OFDM scheme

Disclosed is an apparatus and method for allocating downlink/uplink subchannels for a soft handover in a broadband wireless access communication system, wherein the method includes the steps of configuring FUSC subchannels based on a predetermined FUSC subchannel configuration scheme by using an equal seed value in all cells; allocating a predetermined number of FUSC subchannels of the configured FUSC subchannels as soft handover subchannels; and allocating remaining subchannels, except for the FUSC subchannels allocated as the first subchannels, as non-soft handover subchannels based on the FUSC subchannel configuration scheme by using a specific seed value.
