Abstract

A connection resume request method includes generating, by a terminal, a new access stratum key; sending, by the terminal to a target base station, a connection resume request message requesting to resume a radio resource control (RRC) connection; receiving, by the terminal, a connection resume rejection message from the target base station, wherein the connection resume rejection message indicates that the resuming of the RRC connection is rejected; and resuming, by the terminal, the new access stratum key to a previous access stratum key, wherein the previous access stratum key is an access stratum key that is used, before the apparatus enters an inactive state, by the terminal and the source base station.
