V. CONVERGENCE OF 3GPP 5G AND N3BN IN SSBA

The proposed SSBA can also be extended to converge 3GPP 5G cellular broadband and N3BN (say, DTT) easily. The simplified integration of N3BN (DTT) with 3GPP 5G is shown in Fig. 8. The MBS-related signalling is taken care of by the BSF. However, the data path in the case of DTT content delivery is as follows: AF - BDP - DTT CN - DTT RAN - UE-3. The BSF serves as the integration point for the signalling interplay between 3GPP 5G and the DTT broadcasting network, while the BDP emerges as the point for data path integration.
