Usage
Under congestion, the SGSN can assign the T3346 back-off timers to the UEs and request the UEs not
to access the network for a given (timer value) period of time.
If an Attach Request or RAU Request or Service Request is rejected due to congestion, then the T3346
value will be included in the reject message with GMM cause code 22 (congestion). The MM back-
off timer value sent will be chosen randomly from within the configured T3346 timer value range.
off timer value sent will be chosen randomly from within the configured T3346 timer value range.
If T3346 timer value is configured in a Call-Control Profile then it will override the back-off timer
values defined for either the SGSN Service or GPRS Service configurations.
The timer will be ignored if an Attach Request or RAU Request is received after congestion has
cleared.
Example
Use a command similar to the following to define a T3346 with a timeout range of
2 to 15
minutes.
