FSocket connection between levels

I am working on UE4 for a little while, totally a newbie.
I am handling a problem is, how can I share FSocket connection between levels.
For instance, UE works as a socket server, connection established in Level 1, when Level 1 finished, need to go to Level , then the issue comes, how can I pass the socket connection form Level 1 to Level 2, don’t want to disconnect it, want to use the same one in Level 2, anybody knows that ? please help, many thanks.

use UGameInstance class to include the FSocket.

hmm, but how ? any further tips ?
