Abstract: The present invention provides a data packet routing method and device. When a Switch receives, form an SE, a traffic flow on which service processing is performed, the Switch can determine a forwarding rule of a corresponding service chain according to the traffic flow received from the SE, and route, according to the forwarding rule, a data packet received from the SE. Compared with a case in the prior art in which an SPC needs to deliver a forwarding rule corresponding to each traffic flow to a Switch, the embodiments of the present invention adopt the technical solutions in which the SPC only needs to deliver a forwarding rule corresponding to each service chain to the Switch, thereby reducing signaling interaction between the SPC and the Switch and saving a network overhead.

Abstract: A message transmission method is provided. User equipment may receive a power saving message from a network device, where the power saving message carries indication information of a short message, and the short message includes at least one of the following: a public warning system notification or system information modification information. Then, the user equipment obtains the short message from the power saving message. In this way, when the user equipment is in a connected state, the user equipment may obtain the short message by using the power saving message, for example, a PoSS, instead of by monitoring a paging PDCCH; and when the UE is in a sleep state, the UE is not woken up to monitor the paging PDCCH. This reduces power consumption of the user equipment in the connected state.
