  • Publication number: 20110128944
    Abstract: A femto access point (FAP) for use in a network system and a communication method for the femto access point are provided. A mobile station is wirelessly connected to the FAP. The FAP comprises a storage unit, a sniffer unit, and a process unit. The sniffer unit sniffs a packet of the mobile station. The process unit retrieves an identity (ID) code of the mobile station from the packet and stores the ID code into the storage unit. The process unit further establishes an uplink local area network (LAN) service flow and a downlink LAN service flow of the mobile station. The uplink LAN service flow and the downlink LAN service flow established by the FAP and the mobile station are used to transfer packets within the LAN.

  • Patent number: 7946888
    Abstract: An electrical connector mating with a counterpart connector includes: an insulating housing having sidewalls and endwalls to define a receiving room and a number of contacts retained in the insulating housing. The contact has a first mating portion retained on an outer surface of the sidewall and a second mating portion retained on an inner surface of the sidewall to face the receiving room. The first mating portion and the second mating portion define a U-shaped structure riding on the sidewall. A gap is defined between said first mating portion and the sidewall so that the first mating portion can flexible move in the gap to absorb a dimensional tolerance during the mating process and get a stable connection with the counterpart connector.

  • Publication number: 20110019640
    Abstract: A mobile node (MN), a take-over point of attachment (PoA) and handover methods thereof for use in a heterogeneous wireless network system are provided. The heterogeneous wireless network system comprises a gateway, a first wireless network and a second wireless network which is heterogeneous to the first wireless network. The first wireless network and the second wireless network comprise the take-over PoA and an original PoA respectively. The take-over PoA and the original PoA have an overlapping service area. The MN receives a network service from the gateway via the original PoA so far. As soon as the MN enters the overlap service area, the MN builds a link with the take-over PoA in the data-link layer immediately so that the original PoA may handover to the take-over PoA without interrupting the network service.

  • Publication number: 20100144354
    Abstract: A host apparatus, a mobile station, a serving base station, a target base station, and a communication method thereof for use in a wireless network are provided. The wireless network comprises at least one mobile station, the host apparatus, a serving base station, and a target base station. The at least one mobile station and the host apparatus belongs to a same handover group, and receive a handover request signal from the serving base station. The host apparatus transmits a handover confirmation signal to the serving base station so that the at least one mobile station and the host device of the handover group handover to the target base station. Thereby, the at least one mobile station can be handed over to the target base station without need to transmit the handover confirmation signal, so as to save the bandwidth of the wireless network.
