Abstract: This application provides a plug-in implementation system and method. The system includes a plug-in module and a terminal software module. When the terminal software module does not include a service implementation of a first plug-in interface, the plug-in module may load a default implementation of the first plug-in interface to invoke the first plug-in interface. In this way, a plug-in may be extended to extend a service function of a terminal. In addition, when the plug-in interface is inconsistent with a plug-in function, the default implementation of the plug-in interface is implemented by using the plug-in module, so that an open-source software module can run normally, to ensure normal running of an electronic device as much as possible. Therefore, the open-source software module no longer depends on the terminal software module, and the terminal software module can be decoupled from the open-source software module.

Abstract: Embodiments of this application provide a method for obtaining a target transmission route, a related device, and a system. The method is applied to a flexible Ethernet FlexE networking network and includes: receiving a first message that is sent by a second node for requesting to query for a transmission route of a first FlexE client; and sending a second message to the second node, where a route information entry in the second message includes route information of the FlexE client on each node. Ingress information and egress information that are of a FlexE client on a route node are recorded as a transmission route of each hop. A segment-to-segment transmission route in the FlexE network can be dynamically found in real time, a planned and deployed transmission route is compared with an actually found route, to evaluate a network running status.

Abstract: Embodiments of the present invention relate to the communications field and disclose an access network node, a core network node, and a paging method, for use in a paging process, so as to resolve a problem that a machine to machine (M2M) service cannot be normally used because a network side cannot determine whether a coverage enhancement technology needs to be used in a paging process. In an embodiment, a communications interface is configured to receive a first packet paging message sent by a core network node; a processor determines, according to the first packet paging message received by using the communications interface, that a terminal is an M2M terminal; and a transmitter sends a coverage-enhanced second packet paging message to the terminal.

Abstract: A downlink scheduling data monitoring method, a downlink scheduling data sending method, and an apparatus are provided. The method includes: starting a timer; and after it is determined that the timer expires, monitoring, by using a first discontinuous reception DRX monitoring cycle, downlink scheduling data sent by a base station, where duration of the first DRX monitoring cycle is in a unit of minute or hour. After it is determined that the timer expires, the downlink scheduling data is monitored by using the first DRX monitoring cycle whose duration is in a unit of minute or hour. In this way, not only power consumption is reduced, but also the downlink scheduling data can be monitored.

Abstract: The present invention relates to a method and a device. The method includes: mixing a multi-carrier optical signal with a local optical signal having the same center frequency as that of the multi-carrier optical signal; performing photoelectric conversion and analog-to-digital conversion on an optical signal obtained through the mixing to obtain a digital signal; performing FFT on the digital signal to obtain a frequency domain signal; grouping the frequency domain signal according to each frequency band corresponding to its respective carrier in the multi-carrier optical signal, and performing IFFT on each frequency domain signal group to obtain a corresponding time domain signal for each carrier; and performing data restoration on each time domain signal corresponding to its respective carrier to obtain data carried on each carrier. The solutions of the present invention only require one set of coherent reception device, and have low cost and low power consumption.

Abstract: Data contention caused by multiple threads accessing one data block at the same time when used to execute tasks concurrently may be avoided, and difficulty in detecting and debugging a concurrent error may be reduced. A solution is: adding, according to correspondences between multiple tasks and M data blocks that are accessed by the multiple tasks, each of the multiple tasks to a task queue of a data block corresponding to the task; using N threads to execute tasks in N task queues of M task queues concurrently, where each of the N threads executes a task in a task queue of the N task queues, different threads of the N threads execute tasks in different task queues, and 2≤N≤M.
