Methods and mechanisms for slice-based cell reselection

Systems, methods, apparatuses, and computer program products for cell reselection are provided. A method may include receiving radio mapping information between tracking area identifiers of tracking areas adjacent to a served cell and a list of physical cell identifiers associated with each tracking area, each tracking area associated with a physical cell identifier corresponding to a cell adjacent to the served cell. The slice assistance information may be received from a network entity associated with the device, the slice assistance information maps one or more network slices and at least one of one or more tracking area identifiers of a tracking area in a user equipment registration area or one or more tracking area identifiers of a tracking area adjacent to the user equipment registration area that supports the one or more network slices. Radio mapping information and slice assistance information may be used in a cell reselection procedure. 提供了用于小区重选的系统、方法、装置和计算机程序产品。一种方法可以包括：接收与被服务小区相邻的追踪区域的追踪区域标识符和与每个追
