Abstract: 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.

Abstract: 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.

Abstract: 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.

Abstract: A communication system for providing information on an interface connecting network components comprises: a plurality of user agents for collecting the interface information on the respective network components which form the communication system; a terminal for outputting the interface information on the respective network components in response to a user's request; and a call manager for receiving the interface information on the network components from the user agents through a session initiation protocol (SIP), and providing the terminal with the interface information in real time. A method of providing interface information on the network components comprises steps corresponding to the above-listed functions. Thus, the interface status and information can be exchanged between the network components using the same SIP protocol, and a disabled interface can be dealt with faster.

Abstract: A distributed multi-protocol label switching router determines whether at least one extra label exists in a local label pool having information on allocated labels stored therein and requests allocation of the labels in preset units in a switching control card in response to a determination that no extra labels exists in response to a label allocation request to establish at least one label switched path in a subscriber line card. The labels are allocated at a label pool have information on all labels capable of being allocated in a distributed multi-protocol label switching router stored in preset units therein in response to the label allocation request of the subscriber line card in the switching control card, and the information of the allocated labels is transmitted to the subscriber line card.
