name: NG-RAN
full_form: Next Generation-RAN
context: The NG-RAN selects the security algorithm(s) (encryption algorithm and/or Integrity protection algorithm), instead of MB-SMF selecting (as detailed in step 3), if NG-RAN specific selection of the security algorithm is supported for the MBS traffic. The NG-RAN creates a MB Session Context (if it not already exists), sets it to 'active' state, stores the TMGI and MBS session security context data in the MB Session Context. 10. If NG-RAN prefers to use N3 multicast transport, the NG-RAN joins the multicast group. 11. NG-RAN establishes PTM or PTP DL resources for the MB Session. For the TMGI's PTM MB sessions, the NG-RAN activates the security context and indicates the key index and information required to derive the RAN specific keys (as detailed in clause 6.13.2.2). 12. The NG-RAN transmits the received DL media stream using DL PTM or PTP resources. The NG-RAN uses the MBS session security context data of the TMGI to protect (encryption and/or integrity protection) the DL media stream.
description: The Next Generation Radio Access Network (NG-RAN) is a key component of the 5G network, responsible for providing radio access to user equipment. It plays a crucial role in managing security algorithms, creating and managing MB Session Contexts, and establishing PTM or PTP DL resources for multimedia broadcast sessions.
explanation: The context describes NG-RAN's functions like managing security, session creation, and resource allocation, which are core responsibilities of a network infrastructure.
