Abstract: This application provides a traffic flow identification method and apparatus, and a model generation method and apparatus. The traffic flow identification method includes: A first device obtains a to-be-identified traffic flow, collects statistics about packet header information in the to-be-identified traffic flow in a preset time window, to obtain to-be-identified packet header statistics information, and obtains to-be-identified terminal-side information based on the to-be-identified traffic flow. Further, the first device determines a type of the to-be-identified traffic flow based on the to-be-identified terminal-side information and the to-be-identified packet header statistics information by using a traffic flow identification model. Therefore, the first device can fully consider, by using the traffic flow identification model, attribute information of a device associated with the traffic flow, to improve an identification rate of the type of the traffic flow, and ensure an identification effect of the type of the traffic flow.

Abstract: A cell search method and a communication apparatus. The method comprises: before performing cell search, a terminal device can determine, in combination with the historical access information of other terminal device, whether a cell exists at the position, and adjusts, according to the determination result, the value of the search parameter for cell search, for example, if a cell exists, the search is accelerated by adjusting the search parameter; if no cell exists, the search may not be performed or the search parameter may not be adjusted, so as to reduce unnecessary cell search performed by the terminal device, so that the power consumption of the terminal device can be reduced.

Abstract: A service discovery method and a service discovery apparatus enable a NAN device that does not support a multi-hop service discovery not to respond to a relayed multi-hop service discovery message on the premise that the relayed service discovery message is correctly received by a NAN device that supports the multi-hop service discovery. The method includes: receiving, by a second NAN device, a first service discovery message that is sent by a first NAN device and that is used for a service discovery; and generating, by the second NAN device based on the first service discovery message, a second service discovery message used for the service discovery, and sending the second service discovery message, where the second NAN device serves as a service relay device that relays the service discovery initiated by the first NAN device.

Abstract: A terminal pairing method and a pairing terminal includes acquiring, when a terminal detects a preset pairing trigger event, a pairing hidden value that is of the terminal and that is associated with the preset pairing trigger event; and implementing, by the terminal, pairing with the peer end by using the pairing hidden value of the terminal. Compared with some approaches, in the present disclosure, pairing can be accurately implemented without using an NFC interface, which reduces costs of terminal pairing.
