Trends of Terrestrial Broadcasting Technology Based on MBMS

MBMS 기반 지상파 방송 기술 동향

  • Published : 2021.08.01

Abstract

Multimedia broadcast multicast services (MBMS) have evolved to accommodate broadcasting services in 3GPP standards. One long-standing approach is to comprise the multimedia broadcast multicast service single-frequency network based on the cellular networks of mobile operators, and another approach adds a broadcasting network to 3GPP standards. In this paper, we overview the MBMS architecture and key entities in MBMS services. In addition, the trends of MBMS are discussed in terms of technology and 3GPP standards, where MBMS functionality is described according to 3GPP releases. Finally, we discuss its capability through a comparison with ATSC 3.0, which is the latest terrestrial broadcasting standard, and then we present the current status and future perspectives of MBMS in 3GPP.
