<P>PROBLEM TO BE SOLVED: To provide a method involving a femtocell in communication with an Internet Protocol Multimedia Subsystem (IMS) network. <P>SOLUTION: The femtocell operates according to code division multiple access (CDMA) standards. The method includes receiving, from the femtocell and at a first secure entity in the IMS network, first authentication information generated by the mobile unit using a first random number broadcast by the femtocell in a global challenge. The method also includes receiving, from a CDMA-based authentication server connected to the IMS network, at least one security key formed based on the global challenge. A second secure entity is the CDMA-based authentication server. The method further includes providing the at least one security key to the femtocell in response to authenticating the mobile unit based upon second authentication information. <P>COPYRIGHT: (C)2013,JPO&INPIT |
