Problems solved by technology

[0003] The existing cell reselection technology only performs cell selection based on signal strength, so that the UE is likely to reselect to a cell with better signal quality but cannot provide the required services to the UE, resulting in the UE being unable to obtain the required services and thus unable to achieve Business Diversity of NR Network

Embodiment Construction

[0036]For the NR system, in order to meet the service requirements of human-thing communication, network slicing technology is proposed. Network slicing technology can divide multiple virtual end-to-end network cells on the same hardware infrastructure. Each virtual network slicing cell is logically independent and can adapt to the needs of different service types, providing one or more kind of business. During the mobile process, the UE needs to reselect in time to the network slice cell that supports the required service to ensure normal communication and reduce delay. The existing cell reselection technology does not consider the network fragmentation information and service information of the cell, and only performs cell selection based on the signal quality, so that the UE is likely to reselect a cell with better signal quality but cannot provide the required service for the UE , causing the UE to fail to obtain required services, thereby failing to realize the service d...

Abstract

The invention discloses user equipment, a method for cell reselection therefor, and a computer readable medium. The method comprises the steps: obtaining a cell reselection mode for the cell reselection based on the network segmentation information through the preset information or an instruction sent by a network side; obtaining all neighbor cells with the network segmentation information; and performing the cell reselection based on the network segmentation information and a signal intensity measurement value for all obtained neighbor cells with the network segmentation information. According to the above technical scheme, the method can enable the user equipment to quickly perform reselection to obtain a network segmentation cell of a required service, and achieves the diversified services of an NR network.

Description

technical field [0001] The embodiments of the present invention relate to the communication field, and in particular, to a user equipment, a method for performing cell reselection, and a computer-readable medium. Background technique [0002] In the new radio technology (New Radio, NR) system and the long term evolution system (Long Term Evolution, LTE), the user equipment (User Equipment, UE) in the idle mode needs to monitor the serving cell and the adjacent cell (referred to as the adjacent cell) ) to monitor the signal strength and trigger cell reselection. The purpose of cell reselection is to select a cell with better signal quality than the serving cell. At the same time, in order to avoid frequent reselection shocks, it is required that the signal quality of the better cell be kept at the best for a period of time. Existing cell reselection is divided into intra-frequency cell reselection and inter-frequency cell reselection (including inter-frequency cell reselecti...
