Disclosed is an network access device, comprising: a processing module for generating requirement indication information, wherein the requirement indication information is used to indicate that a user equipment (UE) needs to satisfy a radio resource management (RRM) requirement suitable for a high-speed mobile communication environment, and a sending module for sending the requirement indication information to the UE in a coverage range of a cell. Also disclosed are a user equipment, a communication system and a communication method, which solve the technical problem in the prior art that since a UE moves very quickly, the UE passes through a target cell, but does not complete RRM well; and the UE can adjust an RRM policy according to a pre-set RRM parameter suitable for a high-speed mobile communication environment to shorten a same-frequency cell reselection time, or shorten a target cell identification time, or shorten a synchronization/out-of-synchronization evaluation time, or shorten a measurement period, so as to satisfy an RRM requirement in the high-speed mobile communication environment, and guarantee and improve the network performance. |
