UA-eMBMS for LTE Broadcast
(evolved Multimedia Broadcast/Multicast Service)
The MBMS, which started as a mobile broadcasting service, aligned with the broadband communication technology of LTE and evolved into the eMBMS technology. The eMBMS provides various types of broadcast services such as the news ticker service and datacasting, besides video broadcasting and voice broadcasting. UANGEL has a BM-SC (Broadcast/Multicast Service Centre) solution and MBMS-GW technology that transfers the broadcasting program sent by the BM-SC to the LTE network.
System
| UA-BMSC | BM-SC (Broadcast/Multicast Service Centre) | Performing a function of sending the broadcasting information received from the content provider to the LTE network. |
|---|---|---|
| BMSC Controller | Performing a function of interfacing the broadcasting schedule information with the CP, and transferring it to the pertinent BM-SC. | |
| FR/RR Server (File Repair/Reception Report) | Receiving the streaming packet sending status and network status information from the terminal (increasing according to the terminal increase). | |
| UA-MBMS GW | MBMS GW (MBMS Gateway) | Performing a function of transferring the BM-SC’s control signal to EPC, and propagating the broadcasting data of the BM-SC to eNodeB. |
Key features
