Analyzing the last 10 summary reports of a multicast group
The Last 10 multicast summary reports widget displays all the multicast downlink campaigns. When a downlink is submitted, the network server tries to send it to all the base stations associated with the multicast group. If a base station failed to transmit the downlink over the air, the network server will send the downlink two more times (as a total of 3) before giving up.
The network server is sending a summary report after every try: every 256 seconds for a class B multicast group and every 60 seconds for a class C mulicast group.
|Type||Downlink status||Report type||Percentage of successful downlink transmissions|
|In progress||Partial||≥ 80%|
|In progress||Partial||≥ 30% and >80%|
|Terminated||Final||≥ 30% and >80%|
|Terminated||Final||< 30% Note Downlink partially sent (<30%) is considered if no base station was associated with the multicast group when the multicast downlink was transmitted.|
