The invention discloses a random access method and equipment in a cognitive radio system. The random access method comprises that base station equipment generates a frequency spectrum switch command, the frequency spectrum switch command comprises random access backspacing time parameter information, and the base station equipment sends the frequency spectrum switch command to user equipment in a community to instruct the user equipment to use the random access backspacing time parameter information to initiate a random access process in a frequency spectrum switch process. According to the random access method, due to the fact that the random access backspacing time parameter information is carried in the frequency spectrum switch command, the conflict of random access is inhibited in the frequency spectrum switch process of a CR system, a large amount of user equipment (UE) which intensively conducts random access on a target work frequency point is dispersed in time in advance, the failure probability and delay of random access on the target work frequency point in the frequency spectrum switch process are lowered, and further more, the failure probability frequency spectrum switch and service break period are lowered, and the user experience of the CR system is improved.

The present invention provides a redirection method for a terminal, being characterized in that: the carrier being fixedly resident in the CDMA network for a dual mode terminal is prearranged,the LTE base station sends the redirection information to the dual mode terminal,the redirection information comprises a redirection target carrier configured by the LTE base station,the dual mode terminal and teh CDMA access network perform session negotiation and are informed of the resident carrier appointed by the CDMA access network,both the redirection target carrier and the resident carrier fix the resident carrier in the CDMA network for the pre arranged dual mode terminal,and when the dual mode terminal is rediected to the CDMA network from the LTE network and searches the redirection target carrier in the CDMA network, and initiates the access process on the redirection target carrier in the CDMA network. Compared with the prior arts, the technical scheme provided by the present invention reduces the business break period for redirecting the dual mode terminal from the LTE network to the CDMA network and improves the user experience.

The invention discloses a dual-connection measurement configuration method, a measurement method, a scheduling method and device, a storage medium, a base station and a terminal. The measurement configuration method comprises the following steps: after establishing a main network connection with user equipment, sending main network measurement configuration and candidate auxiliary network measurement configuration to the user equipment; selecting an auxiliary base station according to an auxiliary network measurement report fed back by the user equipment, and determining an auxiliary network first measurement configuration for the auxiliary base station and a candidate auxiliary network measurement gap required for the main base station to complete the auxiliary network first measurement configuration; sending a dual-connection configuration request to the auxiliary base station; and receiving an auxiliary network second measurement configuration and an auxiliary network measurement gap configured by an auxiliary base station, the auxiliary network measurement gap being determined according to a time gap required for the user equipment to complete measurement in the auxiliary network first measurement configuration and the auxiliary network second measurement configuration. Through the technical scheme provided by the invention, the NR measurement task can be completed in a short service interruption time, and an LTE baseband circuit does not need to be changed.

Embodiments of the present invention provide a data transmission method and device for a Layer 2 virtual private network. The method is applied to a network including a primary virtual link and a backup virtual link carried by traffic engineering. The primary virtual link passes through An upstream node and a downstream node, the method includes: the upstream node detects the connection status of the communication link to be protected between the upstream node and the downstream node, and determines whether the communication link to be protected fails; if the communication link to be protected fails, Then the upstream node performs traffic engineering fast rerouting switching, and switches the data transmission to the pre-established standby label switching channel for protecting the communication link to be protected; the upstream node triggers virtual link switching. In the embodiment of the present invention, when a link fails, local protection is performed through traffic engineering fast rerouting first, and then the virtual link is smoothly switched, thereby improving the speed of fault detection and traffic switching, and reducing the time when a link fails. business interruption time.
