Abstract: A user equipment and a method for selecting a public land mobile network (PLMN) are provided. The method includes performing a PLMN selection, wherein the PLMN selection is configured to be used in a standalone non-public network (SNPN), obtaining at least one mobile country code (MCC) from a wireless communication service provider according to the PLMN selection for the SNPN, and storing the at least one MCC.

Abstract: Disclosed in the embodiments of the application are a random access method, network device and terminal device. The method comprises: a network device receiving a plurality of preambles transmitted by a terminal device in a random access process; and the network device returning at least one Random Access Response (RAR) corresponding to at least one preamble in the plurality of preambles to the terminal device as feedback. The method, network device and terminal device in the embodiments of the present application are advantageous and increasing the reliability of preamble transmission and a probability for a network device to respond to a preamble.
