The present embodiment realizes a kind of method of single multicast switching at runtime in network, is being currently under unicast case,
I.e. eMBMS intelligent platform is not when opening eMBMS function, as it is shown on figure 3, the method includes following
Several steps:
Step 301:eMBMS intelligent platform obtains the UE number of each unicast service of region and each UE
Wireless state information；
Concrete, as shown in Figure 4, eMBMS intelligent platform receives each list that region eNodeB forwards
Broadcast the services addresses request of the UE of business, detect (DPI) function record traffic address by depth data bag
User IP in request and S1-APID, and receive the business corresponding with services addresses request that server returns
Address, adds up the UE number of each identical unicast service in statistical time range, and passes through user according to services addresses
IP and S1-APID inquires the wireless state information of each UE from described eNodeB；Described wireless status is believed
Breath includes: MCS grade, layer number and SINR etc..Here, the request of described services addresses can be video
Fragment request, corresponding services addresses can be video slicing address.

The average MCS grade of the UE of described each unicast service is by by the MCS grade of the UE of each unicast service
Averagely obtain；
As considered the unidirectional reliability of broadcast, broadcast MCS grade is generally compared with clean culture MCS the lowest grade and cannot
Use MIMO i.e. cannot obtain the throughput gain of multiple layer, by condition that unicast handover is multicast such as
Under:
(the UE average of unicast service) * (the average MCS grade of the UE of each unicast service)-broadcast
MCS grade * (the average layer number of the UE of each unicast service) > 0；
Described income prioritization criteria may is that and judges that whether unicast resource consumed flow total price is more than broadcast resource
Consumed flow total price, if it is greater, then be multicast by unicast handover, opens eMBMS function, if greatly
In, then multicast is switched to clean culture, closes eMBMS function；This criterion considers the income of operator
Maximize, such as, by the condition that unicast handover is multicast be:
Each business UE number summation * eMBMS business unit price > each business UE number summation * unicast service unit price；
As shown in Figure 4, determine be multicast by unicast handover time, eMBMS intelligent platform start broadcast under
Sending out flow process, particularly as follows: simulation UE forwards the request of described services addresses to server, caching server returns
With services addresses services addresses corresponding to request, by notification message (notification) and region
Business declaration notify that each UE unicast handover is multicast, and according to the wireless state information of each UE, configuration
Multicast MCS grade in current region.
