20130005388 | WIRELESS COMMUNICATION SYSTEM, FEMTOCELL BASE STATION AND TRANSMISSION POWER CONTROL METHOD - A wireless terminal transmits a result of measuring received power of a downlink wireless signal from a femtocell base station to a macrocell base station. The macrocell base station transmits an interference control request including identification information of the wireless terminal to a femtocell base station group of which received power of a downlink signal included in a measurement result transmitted from the wireless terminal is a predetermined value or more. The femtocell base station has an adjacent wireless terminal list in which identification information of a wireless terminal, which is capable of being connected to an adjacent femtocell base station but is not capable of being connected to the femtocell base station, is recorded, and downlink transmission power of the femtocell base station is reduced when the identification information included in the interference control request is included in this list. | 01-03-2013 |
20130039343 | MOBILE WIRELESS SYSTEM, ACCESS POINT DEVICE, AND HANDOVER PROCESSING METHOD - A mobile wireless system includes a first gateway (L-PGW), a second gateway (PGW), a first access point (HeNB) capable of establishing a communication path simultaneously with the first and second gateways, and a second access point (eNB) capable of establishing a communication path only with the PGW. When a mobile terminal connected to the HeNB and communicating with a communication destination node using a first path through the L-PGW switches a connection destination to the eNB, the HeNB establishes a second path through the HeNB and the PGW, while maintaining the first path. The HeNB transmits data, which has been transmitted to the HeNB along the first path, to the eNB along the second path, until the UE is connected to the eNB, and a third path to the communication destination node through the PGW is established. Accordingly, an interruption time of data reception involved in handover is shortened. | 02-14-2013 |

Accordingly, it is possible to improve the throughput for the visitor macrocell user. | 05-23-2013 |
20130208660 | SERVING GPRS SUPPORT NODE AND CONTROLLING METHOD - A system is provided which is capable of connecting a call without degrading the security level in a mobile terminal network, even when a call addressed to a user equipment (UE) arrives via the Internet or a home network. A femto base station receives a packet addressed to a UE via the Internet or a home network, and starts a paging procedure. The UE establishes an RRC connection to the femto base station. The UE transmits, to the femto base station, a paging response addressed to the SGSN. The femto base station performs NAS verification. If the femto base station detects the paging response to a paging request that the femto base station itself has issued, the femto base station changes the service type of the service request received from the UE from the paging response to signaling. | 08-15-2013 |
