Introduction

26.3483GPPNorthbound Application Programming Interface (API) for Multimedia Broadcast/Multicast Service (MBMS) at the xMB reference pointRelease 17TS

The present document defines a northbound interface between the BM-SC and the content provider. The interface is called xMB. Both external (3rd party) content providers and 3GPP defined API invokers e.g. GCS AS can use the xMB reference point to access BM-SC provided delivery services.

The xMB reference point supports different session types, such as generic file delivery e.g. for MCData, application streaming, including DASH streaming, RTP ingest and ingest for transparent delivery. The xMB reference point supports unicast delivery of content, e.g. for devices outside of the MBMS coverage area.

The xMB reference point is fully integrated into the Common API Framework for 3GPP Northbound APIs (CAPIF).
