name: MKFC
full_form: Multicast Key Floor Control
context: TS 33.179 [7] specified a different key distribution mechanism for the distribution of group multicast keys (MKFC). To allow MCPTT clients to operate with legacy MCPTT servers (as defined by the functionality in TS 33.179 [7]), MCPTT clients shall support the MKFC key distribution mechanisms defined in clause H.2 with the following constraints: - The MCPTT client shall reject MKFCs received from other MC systems (based upon the GMS identity). - The MCPTT client shall discard previously received MKFCs upon attaching to a new MC system. MCPTT Servers shall not support MKFC distribution. The MCPTT Server shall only support transmission of signalling over a unicast bearer to a legacy MCPTT client (as defined by the functionality TS 33.179 [7]). This shall be detected by the MCPTT Server on the rejection of the MuSiK. MCPTT Servers and MCPTT clients shall support distribution of the MSCCK. The mechanism for the distribution of the MSCCK is defined in clause H.3. NOTE: Void. MSCCK and MKFC
description: Multicast Key Floor Control (MKFC) is a protocol used for distributing group multicast keys in MCPTT systems, enabling secure communication among clients.
explanation: The text explicitly states that MKFC is a protocol used for distributing multicast keys in MCPTT systems. Protocols define rules and procedures for data transmission, which aligns with the definition of a protocol.
