Claim 0:
1. A method for determining a security algorithm, comprising:
determining, by a base station, whether the base station supports a security algorithm of a terminal; and
if the base station supports the security algorithm of the terminal, adopting the security algorithm to perform an integrity security protection on a radio resource control (RRC) connection resume message;
if the base station does not support the security algorithm of the terminal, sending a radio resource control (RRC) connection setup message to the terminal;
further comprising:
receiving, by the base station, an RRC connection resume request message sent by the terminal, and
acquiring context information of the terminal from another base station; wherein whether the base station supports the security algorithm of the terminal is determined according to the context information of the terminal.
