Runs on boot, but not in the background beyond that? Adds support for eMBMS(evolved Multimedia Broadcast Multicast Service), also known as: LTE Broadcast Enables carriers to send content using multicast/broadcast (same content to many users at the same time) instead of unicast(to a single user). It's a more efficient use of network resources compared to users receiving the same content individually. Probably safe to disable if you don't care about multi/broad-casts. https://en.wikipedia.org/wiki/Multimedia_Broadcast_Multicast_Service
