The present application relates to a network slicing information processing method, a terminal device, and a network device. The method comprises: the terminal device receives first information, the first information comprising network slicing information and a limiting condition corresponding to the network slicing information, and the first information being used for determining priority information of a cell or frequency point by the terminal device when performing cell selection or reselection. Embodiments of the present application can be used for determining the cell or frequency point priority information by the terminal device when performing the cell selection or reselection.

This application discloses a handover method and apparatus. During handover, a source RAN node includes, in a handover message, an indication indicating whether a PDU session supports network slice re-mapping and/or an indication indicating whether the PDU session supports network slice fallback. A target RAN node performs admission control based on the indication, and notifies the source RAN node of an identifier of a network slice to which the PDU session is re-mapped or an indication indicating whether the PDU session falls back to a default network slice. The source RAN node forwards the notification to a terminal device. This reduces signaling overheads caused during handover interaction.

The embodiments of the present disclosure provide a handover method and device, capable of taking information on a slice requested to be handed over and/or information on a slice supported by a target network element into account in a handover process, thereby avoiding impact of introduction of network slicing on cell handover. The handover method includes: determining, by a first device, a handover behavior based on target slice information. The target slice information includes information on a slice requested to be handed over and/or information on a slice supported by a target network element. The handover behavior includes: whether to perform handover and/or whether to perform slice remapping or slice fallback during a handover process.

This application relates to the field of communication technologies, and provides a slice access method, apparatus, and system, to reduce a probability that a terminal service fails because a slice that is not suitable for a current to-be-initiated service is matched. The slice access method includes: receiving one or more user route selection policy rules URSP rules from a network apparatus, and performing URSP matching according to the one or more URSP rules. At least one URSP rule in the URSP rules includes indication information, and the indication information indicates to match one or more preset URSP rules or match one or more preset route selection descriptors RSDs. The method is applied to a network slice access procedure.

One disclosure of the present specification provides a method for performing communication by a user equipment (UE). The method comprises the steps of: receiving, from a network, a first message indicating that connection between the UE and a first network slice used by the UE is released, wherein the first message includes time information about a time when the connection is released; and on the basis of the first message, transmitting, to an application of the UE, a second message indicating that the connection is released. The second message includes the time information, and the UE may drive the application by using the first network slice.

Embodiments of the present application provide a wireless communication method, a terminal device, and a network device. The method includes: obtaining, by a terminal device, indication information, the indication information being used to indicate information of an intended slice; and according to the information of the intended slice, performing, by the terminal device, cell reselection or determining whether to trigger a connection establishment procedure in a serving cell of the terminal device

Embodiments of this application provide a node handover method, in which a source donor node sends a handover request message to a target donor node, where the handover request message includes context information of an IAB node and context information of at least one terminal device. The source donor node receives a handover response message sent by the target donor node, where the handover response message includes an identifier of an accepted terminal device in the at least one terminal device and/or an identifier of a rejected terminal device in the at least one terminal device.

Abase station apparatus acquires, for a cell formed by the base station apparatus, a list of area identifiers belonging to a tracking area the same as that of the cell and information of an area identifier of a neighbor cell adjacent to the cell, determines whether or not the area identifier of the neighbor cell is included in the list, and notifies a terminal apparatus of information in which information of the neighbor cell and a result of the determining are associated together.

In a network operating system, a consumed resource manager of a slicing control device manages a resource consumed by a base station. A terminal information manager manages a type of terminal and a service in use. A cell manager manages cell information and creates a neighbor cell list. A movement information acquirer acquires movement information suggesting motion of a terminal. A motion predictor predicts, on the basis of the movement information, a future position or motion of the terminal. A resource controller and sets aside the resource in advance.

A method for processing a slice service is provided. The method is applied to a first device and includes: receiving slice policy information for at least one of a service and a terminal; and determining a slice policy for the at least one of the service and terminal based on the slice policy information. The slice policy is used to determine a slice configuration of the first device for the at least one of the service and the terminal.
