I have a general question regarding CSFB and TAC LAC Mapping.
In my eNodeB i have CSFB configured to both 2G and 3G for example. With different priorities. So, i have high priority 2G CSFB to Cell x LAC x, and low priority 3G CSFB to Cell y and LAC y. Lets call the TAC for the eNodeB cell TAC z
Then in my Cisco MME, i have Map TAC z to LAC x (where LAC x is the 2G LAC).
Now its impossible to map the same TAC to 2 LAC's, so the TAC is just mapped to LAC x.
Does this mean that its only possible to do the CSFB to LAC x??
Because as previously stated, all my eNodeB's have 2 CSFB options to different LAC's.
Thanks in advance
