The method to go back to LTE after a fall back to 3G
Can the fall forward process be improved?
When the SIM has detected LTE service and run though its own fall ward requirements either:
Swap to LTE
or
If Signal level > X Swap
if Signal level > Y < X Delay Z to ensure signal holds
and / or
Delay Z to ensure signal holds
This way fall forward can be accelerated and the parameters are under the users control.
