A negative electrode for a lithium secondary battery of the present invention includes a negative active material including a plate-shaped carbon powder particle agglomerated in a primary structure in which the plate-shaped particle is oriented in a plane direction and laminated. Fine carbon powder particles are then agglomerated to form a secondary structure on the surface of the primary structure such that the resulting particles include fine pores formed on the surface.

A ring protection link (RPL) owner node in a ring network transmits a ring-automatic protection switching (R-APS) frame in a burst mode until blocked ports of all nodes except the RPL owner node have been unblocked, and, if it is determined that all the nodes have been unblocked, transmits the R-APS frame in a continuous mode. In this manner, the time required to unblock all the nodes can be reduced.

A mobile terminal that can transmit voice data an picture, as well as a text message, in the form of a file during an instant messaging (IM) service, and its file transmission method are disclosed. When the IM service starts, a user inputs text to a message window to chat with one or more subscribers, and when voice or image data (picture, handwriting, image, etc.) is inputted while text is inputted, the inputted voice or image data is converted into a file, transmitted to a counterpart subscriber, and displayed in the form of an icon on a message window. The counterpart subscriber can check the voice or picture by selecting the displayed icon.

摘要:
A data forwarding apparatus and method for reducing a HandOver (HO) interruption time in a wireless communication system where a macro cell and a femto cell coexist are provided. An operation method of a Mobile Station (MS) for data forwarding in a wireless communication system includes synchronizing with a serving Base Station (BS) after completing a HO procedure with a target BS, and receiving data packets existing in a queue through an air link directly from the serving BS.

Provided is a network flow-based scalable video coding (SVC) adaptation device. Without permitting a network transmitting end to divide image data into image data having various levels of quality and send the image data having the various levels of quality to all networks, since an adaptation device is installed in a network device of an ingress of a lower network of a subscriber and the adaptation device and the network transmitting end share network information about attributes of a terminal and the lower network of the subscriber so as to provide an image service having image quality corresponding to the terminal to the terminal, network efficiency can be maximized.
摘要:
A method for supporting a Peer-to-Peer (P2P) communication in a wireless communication system is provided. The method includes identifying whether a Mobile Station (MS) is in a wireless communication active state, a P2P active state, or a P2P previous active state, and transiting to the P2P active state if a P2P connection request occurs in the P2P previous active state and transiting to the P2P previous active state if a P2P communication termination occurs in the P2P active state.
摘要:
A method and system for determining a communication mode in a communication system are provided. The system and method include determining whether a first MS and a second MS are located within a preset area where P2P communications are available, estimating a first expected performance that can be achieved when the first and second MSs operate in a cellular communication mode, estimating a second expected performance that can be achieved when the first and second MSs operate in a P2P communication mode if the first and second MSs are located within the predetermined area, and selecting one of the cellular communication mode and the P2P communication mode as a communication mode between the first and second MSs by comparing the first expected performance with the second expected performance.
摘要:
A method and apparatus for allocating frequency resources for peer to peer (P2P) communication between terminals without a base station are provided. The method determines resources used for a direct communication between two terminals in a communication system. The method includes determining uplink frequency resources of a cellular communication system for use in the direct communication between the two terminals, determining a primary maximum transmission power to minimize interference caused by the direct communication on the cellular communication system and performing the direct communication between the two terminals by using the uplink frequency resources and a transmission power less than the determined primary maximum transmission power.
