Abstract: Embodiments of this application disclose a routing management method, used to advertise an address segment routing policy. The method in the embodiments of this application includes: A control plane function assigns an internet protocol IP address to user equipment. The control plane function determines an IP address segment, where the IP address belongs to the IP address segment. The control plane function sends information used to identify the IP address segment to a user plane function, where the IP address segment is used to advertise a routing policy.

Abstract: Embodiments provide a path update method, a device, and a system. In those embodiments, a network device obtains target path information. The target path information includes first path information and/or second path information corresponding to an anchor user plane network element and being allocated to a terminal. The first path information is for establishing a first path between the anchor user plane network element and an access device, and the second path information is for establishing a second path between the anchor user plane network element and an intermediate user plane network element. The network device associates the target path information with a target data packet processing policy. The target data packet processing policy is used to process a data packet received from the first path and the second path.
