name: IKSRVCC
full_form: Integrity Key for Single Radio Voice Continuity
context: KASME_SRVCC. 9. The gNB sends the HO command to the UE, in which the gNB shall include the 4 LSB of the downlink NAS COUNT received from the AMF. 10. When the UE receives the message, the UE shall derive the new KASME_SRVCC key as described in Annex A.21 using the KAMF key and the downlink 5G NAS COUNT estimated from the 4 LSB received form the AMF. The UE shall further derive CKSRVCC, IKSRVCC based on the new KASME_SRVCC key as described in the clause A.12 in TS 33.401 [10] using a downlink NAS COUNT of zero. The UE shall identify the CKSRVCC and IKSRVCC from eKSI (= ngKSI) as the MME_SRVCC does. If the SRVCC handover is not completed successfully, the new mapped CKSRVCC, IKSRVCC and KSISRVCC cannot be used. In this case, the MSC server enhanced for SRVCC shall delete the newly mapped SRVCC security context for the UE, including CKSRVCC, IKSRVCC and KSISRVCC.
description: IKSRVCC is a parameter used in the derivation of security keys for Single Radio Voice Continuity (SRVCC) handovers. It stands for Integrity Key for SRVCC and is derived from the KASME_SRVCC key, which is further derived from the KAMF key and downlink 5G NAS COUNT.
explanation: The context explicitly mentions IKSRVCC as a key derived using specific inputs (KASME_SRVCC key and downlink NAS COUNT) for SRVCC handovers. This indicates that IKSRVCC is a critical network attribute used in the operation of SRVCC, fitting the definition of a Parameter.
