    摘要： A method and system for realizing network switching, and a mobile node are provided. The method comprises: a Local Mobility Anchor receives a Proxy Binding Update message from a second mobile access gateway, wherein the Proxy Binding Update message carries identifier information of the mobile node, the IP address of a first interface, and the IP address of the second mobile access gateway (S302); the Local Mobility Anchor checks in the stored Binding Cache Entry whether the identifier information of the mobile node and the IP address of the first interface exist (S304); if the existence is checked, the Local Mobility Anchor continually judges whether the Proxy Care-of-Address in the Binding Cache Entry is the same as the Proxy Care-of-Address in the Proxy Binding Update message (S306); if the judging result is that they are different, the Local Mobility Anchor determines that the connection of the mobile node is a switchable connection, and determines that the mobile node has the ability of address preservation, then sends a Proxy Binding Acknowledgement message which carries the IP address of the first interface to the second mobile access gateway (S308).

    摘要： A method and system for realizing network switching, and a mobile node are provided. An LMA receives a PBU message from a second MAG, wherein the PBU message carries identifier information of the mobile node, the IP address of a first interface, and the IP address of the second MAG. The LMA checks in the stored BCE whether the identifier information of the mobile node and the IP address of the first interface exist. If the existence is checked, the LMA continually judges whether the Proxy Care-of-Address in the BCE is the same as the Proxy Care-of-Address in the PBU message. If they are different, the LMA determines that the connection of the mobile node is a switchable connection, and determines that the mobile node has the ability of address preservation, then sends the IP address of the first interface to the second MAG.

    摘要： The present invention provides a method and apparatus for discovering a home link in mobile IP, wherein the method includes: an access network assigns an address for a UE when the UE is attached to the network; the UE acquires a home address from the network; the UE compares the address assigned by the access network with the home address, and confirms that the UE is attached to the home link in the case that the address assigned by the access network and the home address are the same. Therefore, with the present invention, it is not necessary to configure the UE in advance, and the participation of the user is also not required. Thus improved application flexibility is provided.

    摘要： A method for synchronizing user data is provided, which includes: when a User Equipment (UE) moves into a coverage area of a new mobility management unit, an old mobility management unit sends an indication of whether a bearer modification procedure is to be triggered to the new mobility management unit, and the new mobility management unit determines whether to trigger the bearer modification procedure according to the indication. A system for synchronizing user data is further provided. By means of the technical solution of the method and the system, the situation that a Quality of Service (QoS) used by a bearer in the new mobility management unit does not match with a bearer QoS of an updated subscription data when a user equipment moves into a coverage area of a new mobility management unit can be avoided.

    摘要： A method and system of radio frequency (RF) power transmission among multiple wireless stations is provided. Control signals for switching a receiving station between a power reception mode and a data reception mode are generated. The control signals provide switching information about which of the modes to switch to, and timing of the switching. In the data reception mode, the receiving station processes an RF transmission from a sending station as a data communication. In the power reception mode the receiving station processes the RF transmission as energy radiation for powering the receiving station. One type of control signal for power mode switching is generated at the MAC layer of a receiving station and sent to the PHY layer of that station for power mode switching. Another type is RTS/CTS control signal exchanged between the sending and receiving stations.

    摘要： Wireless medium reservation for simultaneous transmission of multiple downlink spatial streams to multiple receiver wireless stations during a multi-user transmit opportunity over a wireless medium, is provided. Such a reservation includes reserving a transmission period for simultaneously transmitting data from a transmitting station to multiple intended receiving stations on multiple downlink spatial streams over a wireless communication medium. Reserving the transmission period includes transmitting a request-to-send (RTS) frame to the multiple receiving stations, the RTS frame including a receiver address (RA) field comprising compressed addresses for the multiple receiving stations.
