    Abstract: This application relates to the field of wireless communications technologies, and in particular, to a communication method, apparatus, and system. This application provides a communication method. The method includes: a user equipment sends a first message to a secondary base station, where the first message is used to indicate that an exception occurs on a connection between the user equipment and a master base station; and the user equipment receives a second message sent by the secondary base station, where the second message is used to indicate whether to recover the connection to the master base station. This aims to quickly recover the connection between the user equipment and the master base station through interaction between the user equipment and the secondary base station, thereby reducing interruptions of data transmission and/or signaling transmission, and further improving system performance and user experience.

    Abstract: The present disclosure discloses example communication apparatuses. One example communication apparatus includes sending request information from a first network device to a second network device, where the request information includes an identifier of a network slice, configuration information of a data radio bearer corresponding to the identifier of the network slice, and first general packet radio service tunneling protocol-user plane (GTP-U) tunnel address information corresponding to the identifier of the network slice. Feedback information is received by the first network device and from the second network device, where the feedback information includes second GTP-U tunnel address information corresponding to the identifier of the network slice. The first GTP-U tunnel address information and the second GTP-U tunnel address information identify a user plane tunnel that corresponds to the identifier of the network slice and that is between the first network device and the second network device.

    Abstract: Embodiments of communications apparatuses, systems, and methods are provided in this disclosure. In an embodiment, an apparatus comprises: at least one processor, and a memory storing instructions for execution by the at least one processor to perform operations comprising: sending, to a network node, a first message comprising a first network slice identifier corresponding to a network slice in a first network slice set, wherein the network slice is accessed by a terminal device to a first access-network node, wherein the network node is a first core-network node or a second access-network node to be accessed by the terminal device, and wherein the first core-network node and the first access-network node are comprised in a first communications system; and receiving, from the network node, a first response message comprising a second network slice identifier corresponding to a network slice in a second network slice set.

    Abstract: Example configuration methods and apparatus are described. An example communications system includes a master node and a secondary node that jointly provide a service for a terminal. One example method includes generating configuration information for a signaling radio bearer (SRB) by the secondary node, where the SRB is used to transmit a radio resource control (RRC) message between the secondary node and the terminal. The secondary node sends the configuration information for the SRB to the master node, so that the configuration information for the SRB is sent to the terminal through the master node. The secondary node receives a result of configuring the SRB by the terminal by using the configuration information for the SRB. In this way, the SRB can be established on the secondary node, and used for RRC message transmission between the secondary node and the terminal.

    Abstract: This application provides a communication method, apparatus, and system. The method includes: determining first information, where the first information includes one or more types of information about an associated beam for a random access success of the terminal device, or, information about an associated uplink carrier for a random access success of the terminal device, and/or includes information about a random access channel RACH resource for a random access failure of the terminal device, and the random access failure of the terminal device includes one or more of a 2-step random access failure, a 4-step random access failure, a dedicated RACH resource random access failure, or a common RACH resource random access failure; and sending the first information.
