摘要： A method for processing header compression in wireless network is disclosed in the present invention. The method includes that: the initial context of packet header compression (PHC) is established in a compression side and a decompression side; the state transformation information is transmitted from the compression side to the decompression side when the state of compression is needed to transform; the data packet from the compression side is decompressed by using the state transformation information in the decompression side. According to the present invention, it is possible that the states of variational dynamic parameters are transformed in real-time and the header compression is performed in the media access control (MAC) layer. Simultaneity, a system and apparatus for processing header compression in wireless network are also disclosed in the present invention.

摘要： A packet classification method includes: the encryption node adds or configures classification parameters in the un-encrypted portion of the encrypted IP packets; the classification node classifies the encrypted IP packet according to said classification parameters. There are still a system, an encryption node and a classification node for packet classificating. The classification node is able to read the classification parameters of the un-encrypted portion after receiving the encrypted IP packets. There are still multiple methods for obtaining classification parameters, and so that the classfication flexibility is improved.

摘要： A method, device and system for measuring a round-trip delay are provided. The method includes that a corresponding pre-estimating forward time for activating the ranging of a terminal and a measuring base station is determined; a ranging process between the terminal and the measuring base station is activated based on the corresponding pre-estimating forward time; a round-trip delay RTD value between the measuring base station and the terminal is obtained based on the pre-estimating forward time and the ranging process. By the provided method for measuring the round-trip delay, the measuring base station can calculate the RTD value in Ranging process based on the pre-estimating forward time and a corresponding time adjustment value when the ranging achieves a success state; and the problems in the available prior art are overcome that only terminal can know RTD first, and the RTD measuring result can be reported to the network side only by the terminal.

摘要： A method, device and system for measuring a round-trip delay are provided. The method includes that a terminal receives the second message from a service basic station, and a position indication information or a measuring basic station number information is carried in the second message; the terminal choices one or more than one basic stations which can realize the position to act as the measuring basic stations based on the position indication information, or the terminal choices correspondence number basic stations to act as the measuring basic stations based on the measuring basic station number information; the terminal and the choice measuring basic station implement a ranging process, and gain a value of round trip delay RTD between the terminal and the measuring basic station. In the provided method method, device and system for measuring the RTD, by designating that the scan is based on position in the scanning process clearly, the terminal can choice correspondence number basic stations to implement the ranging process based on a position requirement, and because it is not have to report the RTD measuring result after implementing the distance measuring processes with all of the consecutive basic stations, it raises the position rate observably.

摘要： A mobile IP system and a method for updating home agent root key, the method comprises the following steps: before the old HA-RK expired, AAA server generates and sends a new HA-RK previously, so that the time slot between the time of expiration of the old HA-RK and the time of acquirement of the new HA-RK is eliminated, and the MIP registration could be completed without slots. The lifecycle of the HA-RK in the system is longer than the MSK's. In the process of EAP, if the remaining life time of the old HA-RK is shorter than, or equal to the lifecycle of the MSK, then the new HA-RK is sent, else the new HA-RK isn't sent. If there are both the new and old HA-RKs available at the same time in the network side entity, then either the old HA-RK is used until its lifecycle ends, and the new HA-RK is started to use, or the new and old HA-RKs are used at the same time, the SPI is used to distinguish.
