Abstract: The present disclosure relates to paging methods and apparatus. One example method is applied to a first access network device. The first access network device belongs to a first network, a second access network device belongs to a second network, and the first network may be different from the second network. When UE accesses the first network and downlink data of the second network arrives, the UE may receive the data of the second network. The first access network device receives downlink data of a terminal from a first core network device, where the first core network device belongs to the first network.

Abstract: This application discloses a communication method and an apparatus. In a solution of this application, a base station sends, by using dedicated signaling, at least one random access parameter set to a terminal in a connected mode or an inactive mode. The base station receives a random access request of the terminal in a connected mode or an inactive mode. One of the at least one random access parameter set is used in the random access request. In this application, differentiated random access processes may be performed in different scenarios.

Abstract: This application provides a communication method, an apparatus, and a system, to improve communication efficiency. One method includes: sending, by an access network node to a terminal device, indication information indicating to transmit a quality of service (QoS) flow by using a bearer, wherein a protocol stack corresponding to the bearer supports transmission of the QoS flow through a first path, wherein the first path passes through one of (1) a service data adaptation protocol (SDAP) layer of a master node and a protocol layer below an SDAP layer of a secondary node, or (2) an SDAP layer of the secondary node and a protocol layer below an SDAP layer of the master node; and transmitting, by the access network node, the QoS flow by using the first bearer.

Abstract: This application provides a handover method in a mobile network and a communications apparatus. The method includes: sending, by a target access network node, a path switch request to a first core network node, where the first core network node is an access and mobility management function supported by both a source access network node and the target access network node, and the path switch request includes indication information of at least one semi-accepted flow/session/radio bearer; and receiving, by the target access network node, a path switch request reply sent by the first core network node, where the path switch request reply includes at least one of the following parameters: a flow/session/radio bearer whose path is successfully switched, a flow/session/radio bearer whose path fails to be switched, indication information of a new network slice, or a context of a modified flow/session/radio bearer.
