| Description | The T3-RESPONSE timer for retransmission. This timer is started
by GGSN, upon the transmission of a signalling request message; it is
used for message retransmission purposes, in the event that no response
is received by the time the timer expires. Note that the total wait
time (cgprsGtpT3ResponseTimer*cgprsGtpN3Requests) must be shorter than
the Mobile System (MS) wait time between retries of Attach and RA
Updates; The product of cgprsGtpT3ResponseTimer and cgprsGtpN3requests
must be less than the minimum value of the Attach Timer(T3310) and the
Routing Area Update timer(T3330). The cgprsGtpT3ResponseTimer timer,
according to the standards, recommends an adaptive back-off mechanism,
using increasing values, e.g., 1, 2, 4, and 8 seconds. |
