Embodiment Construction

[0046] When a UE in an idle state performs cell reselection, the base station can specify the priority of the cell frequency through system information (System Information) or dedicated RRC signaling, and the UE first tries to camp on the frequency with the highest priority. However, the frequency priority sent by the base station can only reflect the service priority set by the telecom operator, but cannot reflect the service preference of the user using the UE. Therefore, the cell where the UE resides may not support the service that the user is interested in.

[0047] In the embodiment of the present invention, when the user terminal camps on a cell, from the mapping relationship between the network slices supported by the user terminal and the cell frequency issued by the core network, the network slice with the highest priority corresponding to the user terminal is selected according to the required service type. Network slices, and try to camp on the cell frequency corres...

Abstract

The invention provides a user terminal and a mobility management method thereof, a base station, and a readable storage medium. The mobility management method comprises the following steps: when attached to a core network, obtaining a mapping relationship between network slices supported by the user terminal and issued by the core network and the cell frequency; determining the network slice withthe highest priority corresponding to the user terminal, comprising: determining the priorities of the network slices in the mapping relationship between the network slices and the cell frequency according to a required service type of the user terminal, and obtaining the network slice with the highest priority; and lingering on the cell frequency corresponding to the network slice with the highest priority. By adoption of the above scheme, the user terminal can linger on a service cell of interest.

Description

technical field [0001] The embodiments of the present invention relate to the field of wireless communication, and in particular, to a user terminal, a mobility management method thereof, a base station, and a readable storage medium. Background technique [0002] With the development of wireless communication technology, 5G wireless communication system is getting closer to practicality. The concept of network slicing (network slicing) is introduced in the 5G system, and operators provide different types of services for user equipment (UE) in different slices. Within a tracking area (Tracking Area, TA), the slices supported by the network remain unchanged. [0003] When an idle state UE is performing cell reselection, the base station can specify the priority of the cell frequency through system information (System Information) or dedicated radio resource control (Radio Resource Control, RRC) signaling, and the UE first tries to camp on the highest priority cell. frequenc...
