[0154] In some embodiments, the network device can configure corresponding RACH partitions for different characteristics / characteristic combinations, and a subsequent terminal can initiate random access according to the RACH partition resources, and the subsequent network device can determine the corresponding characteristics / characteristic combinations according to the RACH partition feedback of the terminal.

[0155] Optionally, the terminal first determines the characteristic or combination of characteristics triggering this RACH, and determines whether there is available RACH resource corresponding to the characteristic / combination of characteristics triggering RA based on the RACH partition configuration provided by the base station, if not, selects the legacy RACH resource (i.e. the RACH resource not associated with any characteristic indication), if there is one, selects the RACH resource, and if there are multiple, performs resource selection based on the characteristic priority configured by the network.

[0156] Optionally, due to the limitation of random access resources and actual network deployment, the network may not provide specific RACH partitions for all characteristic combinations, i.e. there are certain characteristic combinations that cannot find corresponding RACH partitions. In this case, the terminal MAC layer performs RACH partition selection based on the characteristic priority configured by the network, to ensure that high-priority characteristics can find corresponding RACH partitions. That is, the RACH partition finally selected by the terminal may not be able to support all characteristics / characteristic combinations applicable to this RACH.

[0157] In some embodiments, from the perspective of the network device, the base station provides the terminal with the supported NSAG and the corresponding configuration of the NSAG for slice-based cell reselection and RACH configuration enhancement. Meanwhile, the core network delivers the NSAG information (including the correspondence between S-NSSAI and NSAG, NSAG priority and corresponding TAI) and S-NSSAI to the terminal through NAS signaling, for the terminal to map the required S-NSSAI to the NSAG and perform cell reselection and RA based on the NSAG configuration.

[0158] From the perspective of the terminal, the terminal receives the S-NSSAI (S) and NSAG information (including the correspondence between S-NSSAI and NSAG, and NSAG priority and TAI information) delivered by the core network through NAS signaling, and the terminal NAS layer delivers one or more slice and slice grouping information to the AS layer for the AS layer to determine the NSAG ID for cell selection and reselection.
