Reply To: IRAT PS Fail (Target Cell : 2G ALU )


hi styrax,

Is there a way, with counters or traces, to know whether the failure occur during preparation phase on the 2G side, or during the radio phase, when the ue actually leaves the 3G and try to connect to the 2G ?

FYI, in our network, we forbid the 3G2G PS IRAT : it was found to be better for customer to keep PS transfer in worst possible conditions, and drop / reconnect to 2G, rather than allow 3G2G PS Irat.
The time for 3G2G PS irat is so slow, it makes sense to forbid it.
