Abstract: Methods and apparatuses for acquisition of an Address Resolution Protocol (ARP)/IPv6 neighbour cache at a user plane function (UPF) entity without performing deep packet inspection for every packet that traverses a network. The ARP broadcast/Internet Control Message Protocol version 6 (ICMPv6) neighbour solicitation multicast from any Ethernet client (a user equipment (UE) or clients behind the UE or clients in a data network (DN)) is responded to by the UPF entity itself, by looking up the ARP/IPv6 Neighbour cache built in the UPF entity, irrespective of whether the UPF entity acts as the core Ethernet switch or whether the core Ethernet switch is in the DN. The solution is simplified to always intercept ARP at the UPF entity and respond to it based on a local ARP/IPv6 Neighbour cache.

Abstract: A communication method, a communications device, and a communications system to avoid, when an access and mobility management function (AMF) entity fails, a case in which a re-registration process of a terminal that is being served is triggered because a context of the terminal is lost. The method includes: obtaining, by a communications device, a first group identifier of a terminal group to which a first terminal served by a first mobility management entity belongs; and sending, by the communications device, a message related to the first terminal to a second mobility management entity based on the first group identifier when an exception occurs in the first mobility management entity, where the second mobility management entity is a mobility management entity in which a context of the first terminal exists.

Abstract: The present application discloses a DCN processing method for a PLMN that is applied to a network sharing scenario. An access feedback message of a network side is received, and selection assistance information of a DCN and an identifier of a PLMN that serves UE are obtained from the access feedback message, so as to know a PLMN that is actually accessed by the UE. A correspondence between the selection assistance information of the DCN and the identifier of the PLMN that serves the UE is stored. When the UE moves to coverage of the PLMN, a requested DCN to be accessed can be directly determined according to the correspondence, and a RAN node is requested to access the determined DCN. Therefore, a redirection process is reduced, and resource overheads are reduced.
