access-type type
One of the following must be selected to reallocate on the basis of the type of network access:
gprs
umts
This keyword can be used in combination with other keywords to refine the reallocation configuration.
frequency frequency
Defines frequency of the reallocation based on the number of messages skipped. If the frequency is set for 1,
then the SGSN skips 1 message and then reallocates on receipt of the 2nd (alternate) request message,
essentially reallocating the P-TMSI every time. If the frequency is set for 12, then the SGSN skips
reallocation for 12 messages and reallocates on receipt of the 13th request message. This keyword can be
used in combination with other keywords to refine the reallocation configuration.

frequency
must be an integer from 1 to 50.
By default, frequency is not defined and, therefore, reallocation is done for every request message and none
are skipped.

interval
minutes
Enter an integer between 1 and 1440 to define the time interval (in minutes) for skipping the

routing-area-update [ update-type ]
Enables/disables P-TMSI reallocation for RAU (routing area update) with local P-TMSI. To refine the

Important:
Inter-SGSN RAU will always be reallocated.
