Abstract
Methods and apparatuses are described herein for registration and security for wireless transmit/receive units (WTRUs) with multiple universal subscriber identity modules (USIMs). Optimized registration and authentication procedures, that enable a WTRU to register and authenticate multiple USIMs during one registration and authentication procedure are described herein. The techniques described herein may eliminate the need for separate registration and authentication procedures for each USIM. A gateway device may inform the network in a Registration Request message that it is registering multiple devices (i.e., multiple WTRUs). The network and the gateway may then perform an authentication procedure with an aggregate challenge/response (i.e., a single challenge for each WTRU). A WTRU may inform the network in a Registration Request message that it is registering multiple USIMs. The network and the WTRU may then perform an authentication procedure with an aggregate challenge/response (i.e., a single challenge for all USIMs).
