Android Question wifi disconnected when screen off

hi
I'm created a program that connects to a Wi-Fi using the "network" library , Everything works fine, but when the mobile screen turns off, the connection is lost :(
What should be done so that when the mobile screen is turned off, the connection is still in place and not disconnected?

Code:
#Region  Service Attributes
    #StartAtBoot: true
#End Region

Sub Process_Globals
    Dim WiFi_Socket As Socket
    Dim TcpStreams As AsyncStreams
    Dim ServerSocket1 As ServerSocket
    Dim ServerIp As String = "192.168.4.1" 'IP Access point
    Dim Port As Int = 80 'port
End Sub

Sub Service_Start (StartingIntent As Intent)   
    WiFi_Socket.Initialize("WiFi_Socket")
    WiFi_Socket.Connect(ServerIp,Port,0)
    ServerSocket1.Initialize(0,"")
End Sub

Sub WiFi_Socket_Connected (Connected As Boolean)   
    If Connected = True Then
        'connected'
        TcpStreams.Initialize(WiFi_Socket.InputStream,WiFi_Socket.OutputStream,"tcpStreams")
    Else
        'disconnected'
    End If      
End Sub

Sub TcpStreams_NewData (Buffer() As Byte)
    .
    .
    .   
End Sub

Sub Service_Destroy

End Sub

don't know if it helps, but if it's not a problem for you to keep the screen on then:
B4X:
Sub Process_Globals
    Dim screen1 As PhoneWakeState   
End Sub

Sub Activity_Pause (UserClosed As Boolean)
    screen1.ReleaseKeepAlive
End Sub

Thanks @f0raster0

Yes, this is a problem because the connection may take too long and the mobile screen may turn off for any reason.
