  • Patent number: 9332588
    Abstract: A method, an apparatus and a system for information transmission are provided. The method includes the following steps. A second user equipment receives update information issued by a wireless access point (AP). The second user equipment is located within a coverage area of the wireless AP. After detecting that the second user equipment has the update information, a first user equipment establishes a connection with the second user equipment and obtains the update information from the second user equipment. A wireless AP of the first user equipment is located outside the coverage area of the wireless AP. In the present invention, the user equipment can update the information without additionally increasing the transmit powers of the wireless AP and the user equipment when located outside the coverage area of the wireless AP, and thus the interference to other equipments is not increased.

  • Patent number: 8155006
    Abstract: A method for adjusting data rate in a network is disclosed. In the method, when a device is added to the network, a data rate controlling parameter is configured, and when there is a new service or the requirements of a service have been changed, the data rate will be adjusted by modifying the data rate controlling parameter of a source device and/or a transfer device. Therefore, the fairness among these devices would be guaranteed, and the congestion over the network would be mitigated. The present invention also discloses a wireless communication system, a data rate adjusting device, and a topologic server.

  • Publication number: 20090044258
    Abstract: The present invention provides a communication method and device in personal area network, the method for communication between device in a PAN includes: a central device in the PAN receives from a first device in the PAN a communication request for communication with a second device in the PAN; the central device authenticates the first device and the second device; and a point-to-point connection is established between the first device and the second device. Since no access to the access network and the core network is needed during security authentication, thus reducing the signaling traffic of the access network and the core network.
