<p>The present invention provides a method, system and an enhanced SGSN for creating a key between a GERAN and an enhanced UTRAN. The method comprises the following steps: when a user equipment moves from the GERAN to the enhanced UTRAN, the enhanced SGSN servicing the enhanced UTRAN obtains the security-related parameters from the GERAN and generates an air interface key for the enhanced UTRAN according to the security-related parameters; and/or when the user equipment moves from the enhanced UTRAN to the GERAN, the enhanced SGSN servicing the enhanced UTRAN generates the air interface key for the GERAN and sends the air interface key to the GERAN.</p> |
