    Abstract: A service node updating method is provided. The method is performed by a terminal device and includes: receiving configuration information, where the configuration information includes first connectivity configuration information used to maintain both a connection to a source node and a connection to a target node in a service node updating procedure and second connectivity configuration information used to release the connection to the source node and connect to the target node; processing, by applying the first connectivity configuration information, a layer 2 protocol entity corresponding to a bearer between the terminal device and the source node, to reconfigure the bearer as a source node split bearer; and processing, by applying the second connectivity configuration information, a layer 2 protocol entity corresponding to the bearer, to reconfigure the source node split bearer as a target node bearer.

    Abstract: This application discloses a control method and apparatus for obtaining an emergency service, a terminal, and a readable storage medium. The method includes: obtaining access control information provided by a cell, where the access control information is used to indicate whether a terminal working in a target network mode is supported in obtaining the emergency service; and in a case that a network mode in which the terminal works matches the target network mode and that the access control information indicates that the terminal working in the target network mode is supported in obtaining the emergency service, determining that the cell is a cell in which the emergency service is available.

    Abstract: A split bearer control method and a related device are provided. The split bearer control method applied to a terminal includes: a target split bearer is configured for the terminal, a data duplication function is configured for the target split bearer, the target split bearer includes N transmission paths, and N is a positive integer greater than 2; the terminal receives split bearer indication signaling sent by a network-side device; and the terminal activates or deactivates the data duplication function in response to the split bearer indication signaling.

    Abstract: The present disclosure provides a bearer control method, a terminal, and a network side device. A target radio bearer RB corresponding to the terminal is configured with a data duplication function, the target RB is configured with N transmission paths, N is an integer greater than 2, and the method includes: receiving an indication message sent by a network side device, where the indication message is used to indicate to activate or deactivate the data duplication function of the target RB, and/or is used to indicate to activate or deactivate a transmission path of the target RB; and determining an available transmission path of the target RB according to the indication message.

    Abstract: Embodiments of this disclosure provide a serving node update method and a device. The method includes: sending a first message to a target node; receiving, from the target node, a second message used for responding to the first message; and sending a third message to a terminal device when the second message indicates that the target node rejects a multi-connectivity serving node update, where the third message is used to indicate the terminal device to perform a serving node update in a legacy serving node update manner.
