Abstract (en)

[origin: WO2009105249A1] Example embodiments provide a method for performing handovers and key management while performing handovers. The method includes communicating a random handover seed key protected by a secure protocol from a core component of a network to a user equipment. The secure protocol prevents the random handover seed key from being learned by base stations supported by the core component of the network. The secure protocol may be non-access stratum signaling of an evolved packet system environment for wireless communications.
