    Abstract: Disclosed are a time synchronization method and system. The method comprises: an NE1 and the upstream nodes of the NE1 are classified into the first level, and the downstream nodes of the NE1 are classified into the second level, where the first level priority of the first level is higher than the second level priority of the second level; an NE3 connected to the NE1 through a PTP synchronization link in the downstream node receives a first device priority of the NE1 and the first level priority from the NE1; and after the NE3 receives the second device priority of an NE2 and the second level priority sent by the NE2 in the downstream nodes which is connected to the NE1 through the 1PPS+TOD synchronization link, determines that a clock parameter of the NE1 is optimal, and synchronizes the local clock to the NE1.

    Abstract: The present disclosure discloses a method for managing release of a network port of a mobile terminal, and the method includes: during a PPPoE dialup or after completion of the PPPoE dialup, network ports of a current mobile terminal are scanned; it is determined whether scanned idle network ports are released erroneously, it is determined whether restoration of connection is desired for an erroneously released network port, and the restoration of connection is implemented according to conditions of current network connection and the PPPoE dialup when the restoration of connection is desired. The present disclosure further discloses a device for managing release of a network port of a mobile terminal. The method and device make it possible to solve a problem that a network port may be released erroneously after a PPPoE connection is established in the prior art.

    Abstract: The present disclosure discloses a dynamic spectrum allocation method and device based on channel management. The method comprises the following steps: a network node generates a channel set according to an available channel list and channel classification information, and maintains and updates the channel set; and the network node selects a spectrum from the channel set and allocates the spectrum. The device comprises: a channel set generation module configured to generate a channel set according to an available channel list and channel classification information and maintain and update the channel set; and a spectrum allocation module configured to select a spectrum from the channel set and allocate the spectrum. The present disclosure can reduce the delay in the spectrum resource reconfiguration of a CR system, improves the overall performance of spectrum resource reconfiguration and increases the utilization efficiency of a spectrum.
