nri-value nri-value
Sets the local NRI. Including this keyword in the configuration instructs the SGSN to check the P-TMSI and
use the SGSN matching the configured NRI value to off load subscribers.
use the SGSN matching the configured NRI value to off load subscribers.
Important:
nri-value
and
target-nri
are mutually exclusive.
nri-value
is an integer from 1 through 63 that identifies a specific, already defined, SGSN in a pool. (NRI
defined in the service configuration.)
Use of 0 (zero) value is not recommended.
Use of 0 (zero) value is not recommended.
stop
Instructs the SGSN to stop offloading subscribers from the pool area.
target-nri target_nri
Instructs the SGSN to begin dynamically load balancing across a network of pooled SGSNs.
target_nri
is an integer from 0 through 63 that identifies an already defined target NRI (SGSN) to which
the subscribers are to be offloaded. (NRI previously defined in the service configuration.)
Use of 0 (zero) value is not recommended.
Use of 0 (zero) value is not recommended.
target-count target_count
Identifies the number of subscribers to be offloaded as an integer from 0 through 4000000. Instructs the
SGSN to begin target count-based offloading.
SGSN to begin target count-based offloading.
t3312-timeout seconds
Sets the timer (in seconds) for sending period RAUs to the MS as an integer from 2 through 60. Default: 4
Usage
Use this command to configure the offloading of subscribers which is a part of the SGSN’s load
redistribution operation. This command can be used anytime an SGSN is to be taken out of service.
Commands, with different NRI values, are repeated to expand/contract the radius of the offloading.
Target count-based offloading and local offloading can not run simultaneously. When target count offloading
is to be used, you should choose an algorithm to control offloading from the perspective of the IMSIMGR
and SESSMGR. This is done with the
redistribution operation. This command can be used anytime an SGSN is to be taken out of service.

command in the SGSN-Global configuration
mode.
Example
The following is a series of two commands to initiate local offloading.
Command 1: The following command instructs the SGSN to begin local offloading for the local NRI id

included in the
gprs1
GPRS service configuration:
sgsn offload gprs-service gprs1 connecting nri-value 1
Command 2: Enter this second command to add offloading for NRI
2
to the offloading already occurring for
NRI

:
sgsn offload gprs-service gprs1 connecting nri-value 2
The following is a series of commands to discontinue local offloading and to initiate target count-based
offloading.
