context: of which service is actively transmitting on the signalling plane. Figure 4.2-2 shows the functional model for the common services core. Figure 4.2-2: Common services core functional model The common services core (CSC) functional model shows the major interfaces associated with the various mission critical servers and clients. The MC service server in figure 4.2-2 may represent the MCPTT server, the MCVideo server or the MCData server, while the MC service client(s) may represent the MCPTT client, MCVideo client or the MCData client. As the CSC functional model is applicable to each of the MCPTT, MCVideo and MCData features, it is likely that the existing security mechanisms may be reused. The CSC reference points use variations of SIP and HTTP to fulfil the CSC architecture for the various CSC functional servers (group management servers, configuration management servers, identity management server key management server, location management servers, etc). As there are existing
description: The Common Services Core (CSC) is a network function that provides a set of common services for mission-critical communications, including group management, configuration management, identity management, key management, and location management. It acts as an intermediary between various mission-critical servers and clients, enabling secure communication and reuse of existing security mechanisms.
explanation: CSC is classified as a Network Function based on its role in providing common services for mission-critical communications, as described in the context from 3GPP TS 33.880. The CSC functional model shows its association with various servers and clients, and its use of SIP and HTTP reference points to fulfill its architecture.
