Abstract: A ranging method and apparatus are provided. The method includes: sending a ranging signal to a measured system, where the measured system includes at least one reflection point (S110); receiving a first spectrum signal obtained after the ranging signal is reflected by the at least one reflection point (S120); determining a second spectrum signal according to the first spectrum signal, where the second spectrum signal includes the first spectrum signal, and a spectral width of the second spectrum signal is greater than a spectral width of the first spectrum signal (S130); and estimating a distance of the at least one reflection point according to the second spectrum signal (S140). According to the ranging method and apparatus, a distance of a reflection point in a measured system can be determined in a relatively accurate manner, so as to improve ranging accuracy.

Abstract: A network management method and a controller are provided. Elastic scaling of an in-network packet data network IN-PDN is implemented when UE is migrated or detached. In addition, service continuity in a local network of the UE can still be ensured when the UE is migrated or detached, and an IN-PDN resource that is no longer used is reclaimed in time, thereby avoiding a waste of the IN-PDN resource.

Abstract: Embodiments of the present disclosure describe a network slice determining method and system, and an apparatus. As discussed with respect to the embodiments described herein, in the communications field, a network slice to which a terminal belongs can be determined for the terminal in a 5G network. The method may include obtaining, by a network selection function (NSF) node, an identity of a terminal. The method may also include sending, by the NSF node, the identity to a home subscriber server (HSS), and then receiving, by the NSF node, a slice identifier of the network slice that is sent by the HSS, where the slice identifier is determined by the HSS based on the identity The method may also include determining, by the NSF node based on the slice identifier, a network slice to which the terminal belongs.
