6.3.2 Handover
The mobile network unit moves out of the range of the stationary network unit that it
uses for data transmission to the milling unit and consequently loses the connection.
When it is in range of another stationary unit, the mobile network unit will switch to that
one.
Sequence:
1.
The acquisition unit is pushed into range of stationary network unit B.
2.
The mobile network unit will connect with stationary network unit B.
3.
The acquisition unit is pushed out of the range of stationary network unit A.
4.
Data transmission will be temporarily interrupted.
5.
The mobile network unit will eventually detect that the connection to stationary
network unit A is lost.
6.
The data transmission will continue using the connection to stationary network unit
B.
Notes:
●
This is a hard handover in which no decision process is implemented whether or not
the data transmission could better use the connection to stationary network unit B
when this connection comes available.
