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.

Abstract: Embodiments of this application provide a communication method, a communications apparatus, and a storage medium. The communication method includes: sending, by a new master network device, a request to an original master network device, to request context information of a terminal device on the original master network device and an original secondary network device; and receiving the context information of the terminal device on the original master network device and the original secondary network device from the original master network device. This application can effectively simplify implementation steps of resuming a multi-connectivity mode by the terminal device, reduce signaling procedures, and shorten a delay, thereby improving network transmission efficiency.

Abstract: Embodiments of this application disclose a retransmission processing method and apparatus. The method includes: sending, by a master base station, instruction information to a first secondary base station, where the instruction information is used to instruct the first secondary base station to send feedback information to the master base station after the first secondary base station sends data to user equipment; receiving, by the master base station, the feedback information sent by the first secondary base station according to the instruction information; and performing, by the master base station, retransmission processing on the data according to the feedback information.

Abstract: A network entity is proposed for controlling the use, by a user equipment, of network slices of a communication network comprising a plurality of slice support areas. Each slice support area comprises at least one cell, and all cells of a given slice support area support the same network slices. A registration area for the registration of the user equipment with the communication network comprises at least one slice support area. The network entity is adapted to transmit, to the user equipment, slice support information for at least one slice support area of the communication network. The slice support information for a given slice support area indicates at least one network slice supported by the given slice support area and/or at least one network slice not supported by the given slice support area.

Abstract: A paging collision processing method and a related apparatus are provided. The method includes: upon detecting that a paging occasion in a first camped cell collides with a paging occasion in a second camped cell, a terminal device determines a first paging parameter, and sends a first paging parameter to a first network device corresponding to the first camped cell. The terminal device receives a second paging parameter from the first network device, determines a second paging occasion of a first identity module card in the first camped cell based on the received second paging parameter, and monitors a paging message in the first camped cell on the second paging occasion, which does not overlap a third paging occasion of a second identity module card in the second camped cell in terms of time, thereby avoiding a paging collision that occurs when the terminal device monitors the paging message.

Abstract: In a data transmission method, a terminal device determines a first message, where the first message indicates that the terminal device is to move from a first network to a second network. The terminal device sends the first message to a first network device in the first network. The first network device is an access and mobility management function network element or an access network device.

Abstract: A second access network device determines first load information and sends the first load information to a first access network device. Correspondingly, the first access network device receives the first load information, and uses the first load information. For example, the first access network device determines, based on the first load information, whether to perform an energy saving operation or load balancing. The first load information indicates load that is in a cell of the second access network device and that is associated with a first-type terminal device, the first-type terminal device has a capability of accessing the first access network device and the second access network device, and the first access network device and the second access network device belong to different systems.
