Design of a next generation 5G broadcasting core network in China

The evolved Multimedia Broadcast Multicast Services, eMBMS (evolved Multimedia Broadcast Multicast Service), promises to be a powerful method for distributing common multimedia content. However, rapid deployment of 5G broadcating services in China cannot be supported by eMBMS due to the obstacles of regional simple deployment and one-way interface between core network and RAN (Radio Access Network) side. This article fills the gap by describing solutions for new core network architecture. Two innovative solutions realize the control plane function. The proposed architecture alternative satisfies the objective needs of radio and television service deployment in China and reduces the complexity of signaling processing, which is favorable for collaborative coverage of broadcast and unicast.
