In this embodiment, after in order to guarantee that standby MEC upgrades to new main MEC, (i.e. local service handles net for the side LBP
Network) data to the side eNB can correctly seal up dress, and main MEC needs to backup to user's table data standby MEC, in turn, as standby MEC
When switching is main MEC, flow encapsulation forwarding can be carried out according to user's list item of backup.
For example, when receiving the flow of UE, can be inquired according to the flow received after standby MEC switching is main MEC
Local user's list item determines complete packaging information (including encapsulation IP information, matchmaker according to the content of flow and user's list item
Body access control (Media Access Control, abbreviation MAC) address, Tunnel information etc.), and according to the complete encapsulation
Information is packaged forwarding to flow.
It should be noted that in this embodiment, after UE is offline, main MEC can delete the corresponding user's list item of the UE,
And standby MEC is notified to delete the corresponding user's list item of the UE, to save storage resource.
Further, in one example, standby to standby MEC progress data above by the destination channel between standby MEC
Part, can also include:
When receiving the message of the side UE from local eNB mouthfuls, tunnel-associated table corresponding with the UE is established；
Tunnel-associated table is backed up into standby MEC by destination channel, so that after standby MEC switching is main MEC, according to backup
Tunnel-associated table is packaged forwarding to the flow for actively accessing UE.
In this example, it is contemplated that in the case where video on demand, in fact it could happen that after UE user is online, video server
The case where first accessing UE (actively accessing UE), in order to guarantee that video server active transmission can be forwarded to the data of UE
When UE, main MEC are from the local eNB mouthfuls message for receiving the side UE, the corresponding tunnel-associated table of the UE, the tunnel-associated can establish
It may include the corresponding complete packaging information of UE in table, for example, encapsulation IP information, MAC Address, Tunnel information etc..
For example, when main MEC is from the eNB mouthfuls of messages for receiving the side UE, can be existed according to the five-tuple information of the message
Remaining packaging information is added in user's list item of the UE, to generate tunnel-associated table.
It should be noted that in this example, when main MEC receives the side UE message, it is also necessary to determine to the message into
The processing of row local service enters core net processing.
If being directly forwarded into core net processing by EPC mouthfuls to the message；If carrying out local service processing,
After then being decapsulated to the message, passes through LBP mouthfuls and forward.
When main MEC receives the message of the side LBP, need to be packaged the message according to matched tunnel-associated table
Afterwards, it is forwarded by eNB mouthfuls.
In this example, after in order to avoid active-standby switch, if main MEC new in a period of time does not receive the message of the side UE
Cause video on-demand function unavailable, tunnel-associated table can be backed up to standby MEC after generating tunnel-associated table by main MEC,
It in turn, can be based on backup when standby MEC switching is main MEC, and receives data of the video server active transmission to UE
Tunnel-associated table, according to the destination address information carried in data, dress forwarding is sealed up in the tunnel for selecting an entry to be UE, and is worked as
When receiving backhaul traffic, the tunnel-associated table of an exact matching is resettled, to guarantee active-standby switch rear video point multicast function
