The macro node partitions the unique identifier to determine the address of the femto node. In another embodiment, the femto node registers its address with a domain name system. The macro node queries the domain name system to obtain the address of the femto node. In another embodiment, the macro node sends the unique identifier to a proxy. The proxy partitions the unique identifier to determine the address of the femto node. | 2010-08-19 |

20100208704 | Data Processing Method and Device - A data processing method is provided for forwarding data in the case of handover between heterogeneous networks. The data processing method includes: when a user equipment (UE) is handed over from an originating network to a receiving network, receiving, by the originating network, a data forwarding address obtained by the receiving network; creating a data forwarding tunnel between an originating network gateway and a receiving network gateway according to the data forwarding address; and forwarding data to the receiving network through the data forwarding tunnel. A data processing device is also provided. The lossless data processing solution can overcome the problem of data loss in the case of handover between heterogeneous networks in the existing technology, reduces the time of user service interruption and enhances the user experience. | 2010-08-19 |

20100208713 | WIRELESS COMMUNICATION SYSTEM, WIRELESS COMMUNICATION APPARATUS, WIRELESS COMMUNICATION METHOD, AND COMPUTER PROGRAM - Random access operation is performed under a communication environment in which a plurality of communication modes having different transmission rate coexist with small overhead. A high-grade communication station spoofs information of a packet length and a rate in a decoding portion so that a value of (packet length)/(rate) corresponds to a duration where the communication is hoped to be stopped. The other station receiving the spoofed information receives the rest of the packet with the designated rate during the interval designated by the value of (packet length)/(rate). In this case, the packet length and the rate are not those of actually transmitted packet so that this packet is discarded. | 2010-08-19 |
