Reply To: Recovery on timer expiry

Nitin Saini

Hello All,

Could you help me to answer below questions.

T313 = 30sAn application parameter determines the time supervision period between sending of CONNECT message and receiving of CONNECT ACKNOWLEDGE message using the T313 timer. Value range = 1s-255s
We need to check on the following: – Is there any another timer on the BSC/RNC that is linked to this timer? – In MIC1 network, the timer is set to default (30s), what are the risks of decreasing / increasing this timer? – What could be the advantages of changing this timer value? – what are the possible impact on the call flow? (Delay on call connection….) – What is the particular impact of this timer during an IRAT handover from 3G to 2G? Does this timer has any impact on call drops? – Does the expiry of this timer impact
