context: KSIâPS. The ME shall overwrite the stored parameters CKPS, IKPS , KSIPS , GPRS ciphering key Kc and GPRS CKSN PS if any, with the derived parameters CKâPS, IKâPS, KSIâPS, GPRS ciphering key Kcâ and GPRS CKSNâ PS in both ME and USIM when the SRVCC handover has been completed successfully.. For GSM subscribers, the ME shall derive GPRS Kc' according to annex B.7, using the NONCEMSC received in the CS to PS HO command and the latest GSM Kc. The ME shall set CKSN'PS equal to CKSNCS associated with the latest GSM security context and associate it with the GPRS Kc'. The ME shall in this case also derive CK'PS and IK'PS from the GPRS Kc' using the c4 and c5 functions of the present specification. The ME shall associate the CK'PS and IK'PS with KSI'PS which shall be set equal to CKSN'PS. The ME shall overwrite the stored parameters 64-bit GPRS ciphering key Kc and GPRS CKSNPS, if any, with the derived parameters GPRS ciphering key Kcâ and GPRS CKSNâPS in both ME and SIM when the SRVCC
description: General Packet Radio Service (GPRS) is a packet-switched technology that allows for data transmission over cellular networks, providing higher speeds than traditional circuit-switched methods. It is used in various mobile communication systems, including GSM and UMTS.
explanation: The context describes GPRS as a technology enabling data transmission over cellular networks, highlighting its role in packet-switching and comparison to circuit-switched methods. This clearly classifies it under the 'Technology' category.
