context: request as was carried in step 1. 5. Zn: NAF specific key procedure BM-SC retrieves the NAF specific key material and IMPI of the user. BM-SC further derives MBMS specific key material MRK and MUK as specified in clause 6.1. For detailed signalling flows see TS 29.109 [20]. Table H.2.1-4: Bootstrapping authentication information procedure (BM-SC to BSF) 6. Authentication at BM-SC BM-SC verifies the Authorization header by using the bootstrapping transaction identifier B-TID and the key MRK. BM-SC calculates the corresponding digest values using MRK, and compares the calculated values with the received values in the Authorization header. The BM-SC also verifies that the hostname (i.e. its FQDN) in the realm attribute matches its own. If the verification succeeds, the incoming client-payload request is taken in for further processing. The BM-SC continues processing of the MSK request according to its internal policies. The BM-SC verifies that the subscriber is allowed to receive the
description: The Broadcast-Multicast Service Centre (BM-SC) is a network function responsible for managing broadcast and multicast services in the telecommunications network. It handles key retrieval, derivation of specific key materials, authentication, and authorization procedures.
explanation: BM-SC is classified as a Network Function based on its role in managing broadcast and multicast services, handling key materials, and performing authentication and authorization procedures within the network.
