    摘要： The present invention discloses a method and system for establishing an enhanced key when a terminal moves from an EUTRAN to an enhanced UTRAN, so as to ensure that the terminal can carry out normal communication safely in the enhanced UTRAN. The method includes: when the terminal moves from the EUTRAN to the enhanced UTRAN, a target enhanced serving GPRS support node (SGSN+) in the enhanced UTRAN deducing an intermediate key used in the UTRAN according to a mapped traditional key obtained from a source mobile management entity; and the terminal, after deducing the mapped traditional key, further deduces the intermediate key used in the enhanced UTRAN by using an algorithm which is the same as that of the target SGSN+ according to the mapped traditional key.
