name: RNC
full_form: Radio Network Controller
context: From the RAN Mobility Information message (downlink message 10), the ME deduces from the lack of the IE containing the RNC enhanced UTRAN KH, that the target RNC is a legacy RNC (otherwise the target RNC would have included such an IE). - The ME informs the target about that it is capable of the enhanced UTRAN KH in the RAN Mobility Information Confirm (uplink message 10). A.1.2 Source RNC is not updated A.1.2.1 Target RNC is updated Combined hard handover and SRNS relocation: - The source RNC behaves like any legacy RNC and just forwards the CK/IK used for the air interface protection to the target RNC as they are. - ME knows source RNC is legacy so the ME uses the same CK/IK with the target RNC as with the source RNC. - The ME and the target RNC uses the same keys as was used in the source RNC when communicating. - The ME informs the target about that it is capable of the enhanced UTRAN KH in the uplink RRC message 8. - The target RNC informs the ME about that it is capable of the
description: The Radio Network Controller (RNC) controls and manages radio resources within a UTRAN (UMTS Terrestrial Radio Access Network). It handles handover procedures, SRNS relocation, and key derivations.
explanation: The RNC's role in controlling radio resources, managing mobility information, and participating in handover procedures aligns with the definition of a Network Function.
