Abstract

A wireless device first successfully completes an Inter-RAT procedure, which is either an Inter-RAT handover, Inter-RAT cell reselection or Inter-RAT cell change order from UTRAN procedure. The wireless device then determines if a USIM is present. If the USIM is present, the wireless device determines if a new security key set was received and unused for ciphering and integrity functions during a current RRC connection. If a new key set was present and unused, the wireless device stores a value of zero into the USIM as a security START value for the CN domain associated with the RRC connection.

Description

technical field [0001] The present invention relates to a wireless communication device, in particular to a wireless communication device storing a safe initial value in a non-volatile memory. Background technique [0002] 3GPPTS 25.331 V3.12.0 (2002-09) "Radio Resource Control Specification" and 3GPP TS 33.102 V3.12.0 "Security Architecture" of the 3rd Generation Partnership Project (3GPP) specifications )" both provide a technical description of the Global Mobile Communication System (Universal MobileTelecommunication System; UMTS) and its related security protocols. UMTS is disclosed in wireless communication, including a device (usually a mobile device) called a user equipment (User Equipment; UE) and one or more base stations. These base stations (so-called Node Bs) and their corresponding radio network controllers (Radio Network Controllers; RNCs) are collectively referred to as a UMTS Terrestrial Radio Access Network (UMTS Terrestrial Radio Access Network; UTRAN).
