A method and an apparatus for performing transmission power selection of a wireless access device and channel allocation in a combination manner, for resource management optimized for a wireless network environment supporting multimedia traffic are provided. In a method for managing a radio resource of at least one Access Point (AP) in a wireless communication network, a transmission power select operation for the AP is performed on each of a plurality of channel settings, and a network performance value is predicted. Optimized channel setting is selected among the plurality of channel settings depending on the predicted network performance value. The optimized channel setting and optimized transmission power corresponding to the optimized channel setting are allocated to the AP.

Method and apparatus for managing radio resource in wireless communication system

According to one embodiment, a method for performing a user call forwarding operation through near field communication between a fixed terminal and a portable terminal includes determining that a distance between a first fixed terminal and the portable terminal is within a specified distance, detecting a movement within the specified distance, determining that the detected movement is the same as a specified movement, and requesting call forwarding to the first fixed terminal when the detected movement is the same as the specified movement.

Call forwarding apparatus and method

An operation method and apparatus of a terminal for call move are provided. The method includes, if receiving a call move request signal including registration information of a first device that is in voice communication with a second device from the first device, transmitting, by the terminal, a call state request signal for the first device using the registration information to a server, if determining that a call state for the first device is not a call through the server by using a call state response signal received from the server, establishing, by the terminal, a wireless connection with the first device, and, performing, by the terminal, voice communication with the second device through the established wireless connection.
