The method includes detecting a base station identifier (BSID) of the serving BS and a BSID of each of other serving BSs included in the cooperative communication system; determining an available resource which the serving BS will use and an available resource which each of other serving BSs will use based on the BSID of the serving BS and the BSID of each of the other serving BSs; and transmitting information on the determined available resources to cooperative communication cell member BSs which the serving BS manages. | 11-20-2014 |
20140364128 | METHOD AND APPARATUS FOR HANDOVER IN COMMUNICATION SYSTEM - A method for a serving base station to determine a handover time in a communication system is provided. The method includes determining whether to set up dual connectivity (DC) with respect to a terminal with a target base station that transmits the beacon if it is recognized that the terminal receives a beacon including a plurality of pieces of service coverage area information, and determining whether to execute a handover to the target base station based on a measurement report of the terminal, which is received after the DC is set up if the DC is set up. | 12-11-2014 |
20140369259 | APPARATUS AND METHOD FOR TRANSMITTING/RECEIVING DATA IN MOBILE CONTENT NETWORK - A method for receiving data in a User Equipment (UE) in a mobile content network is provided. The method includes transmitting a request message, which requests a content, to a first Digital Unit (DU), receiving an Internet Protocol (IP)_ADD message, including information of a second DU which caches the content, from the first DU, updating a Stream Control Transmission Protocol (SCTP) connection according to the information of the second DU included in the IP_ADD message, and receiving data from the second DU using the updated SCTP connection. | 12-18-2014 |
20150032906 | APPARATUS AND METHOD FOR ASSIGNING IP ADDRESS IN COMMUNICATION SYSTEM - A method for selecting a source address in a host electronic device is provided. The method includes determining an address type to use in communication of an application which is being executed, selecting a source address based on the determined address type, and setting the selected source address as a source Internet Protocol (IP) address for a transmission packet of the application which is being executed. | 01-29-2015 |
