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： 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 communication in a wireless system using a multiple user transmission opportunity is provided. The data blocks are organized in order of transmission priority based on access categories. Contention for access to the communication medium during a transmission opportunity period is based on a backoff timer of each access category and the transmission priority. Upon successful contention for a transmission opportunity period, during the transmission opportunity period, a data block of a primary access category is wirelessly transmitted from the wireless station to one or more primary destination wireless receivers. Simultaneously, a data block of a secondary access category is wirelessly transmitted from the wireless station to one or more secondary destination wireless receivers. Contending for the transmission opportunity period includes each access category contending for access to the wireless communication medium and a secondary access category selectively invoking communication medium access backoff based on one or more backoff events.
