Use this command to map a UMTS PS core network identifier with a particular SGSN point code.
This command can be entered multiple times with same SGSN point code to map with one or more PS core network Id, but a particular core network identifier can be mapped to one SGSN only.
This command is instrumental in Iu-Flex functionality, whenever HNB-GW receives RESET/RESET-RES messages from SGSN with Global CN-ID information element, the response from HNB-GW is sent to the node configured for that particular Global CN-ID.
If the RESET/RESET-RES messages do not have Global CN-ID IE, then the response of those messages is directed to the default SGSN which is configured using sgsn point-code command in this mode.
Example
The following command configures the PS core network identifier 101 with an SGSN point code 1.2.3:
map core-network-id 101 point-code 1.2.3
The following command configures the PS core network identifier 102 with the same SGSN point code 1.2.3:
map core-network-id 102 point-code 1.2.3

idnns_start must be an integer between 0 through 1023 and should be less than idnns_end.
idnns_end must be an integer between 0 through 1023 and should be more than idnns_start.
The command can be entered more than once to map multiple IDNNS ranges to same SGSN, but overlapping and mapping of same range to different SGSN point code is not allowed.
point-code sgsn_point_code
Specifies SS7 address of SGSN in PS network in point code value to map with range of IDNNS values.
sgsn_point_code must be in SS7 point code dotted-decimal ###.###.### format or 8-digit decimal ######## format.
backup point-code bkup_sgsn_point_code
Specifies SS7 address of SGSN to be used as backup in PS network in point code value to map with range of IDNNS values.
bkup_sgsn_point_code must be in SS7 point code dotted-decimal ###.###.### format or 8-digit decimal ######## format.
Usage
Use this command to map a NRI received from UE during initial PS network node selection to SGSN point code through NRI range mapping over Iu-Flex interface.
The IDNNS refers to the information element in RUA connect message from UE towards RAN (HNB-GW). In IDNNS IE, if the choice of routing mentioned is other than local P-TMSI, then the value it provides is used against this configuration to map the SGSN point code.
If backup SGSN point-code is specified, then specified SGSN works as backup for the IDNS range configured. This Backup SGSN is selected if the mapped SGSN for a given IDNNS range is going for offloading using offload-sgsn point-code command.
The command can be entered more than once to map multiple IDNNS ranges to same SGSN point code, but overlapping and mapping of same range to different SGSN point code is not allowed.
Example
The following command maps the IDNNS range from 101 to 201 with SGSN point code 1.2.3 and point code 7.8.9 as backup SGSN point code :
map nri range 101 to 201 point-code 1.2.3 backup point-code 7.8.9
The following command removes all IDNNS range matching entries between 301 to 399 from the configuration:
no map idnns range 301 to 399
 
map nri range
This command configures the mapping of Network Resource Id (NRI) received from UE to SGSN point code. This is an important configuration for PS network resource sharing over Iu-Flex interface.

no map nri range nri_start to nri_end
no
Removes the entries of mapping of range of NRIs received from UE with particular SGSN point code.
range nri_start to nri_end
Specifies the range of NRIs received from UE to map with particular SGSN point code during initial PS core network node selection.
nri_start must be an integer between 0 through 1023 and should be less than nri_end.
nri_end must be an integer between 0 through 1023 and should be more than nri_start.
The command can be entered more than once to map multiple NRI ranges to same SGSN, but overlapping is not allowed.
point-code sgsn_point_code
Specifies SS7 address of SGSN in PS network in point code value to map with range of NRI values.
point_code must be in SS7 point code dotted-decimal ###.###.### format or 8-digit decimal ######## format.
Usage
Use this command to map a NRI received from UE during initial PS network node selection to SGSN point code through NRI range mapping over Iu-Flex interface.
This configuration is used during initial PS core network node selection when the network resource identifier (NRI) from the UE is available. The NRI range is mapped to SGSN point code. This configuration is used when the core network uses Iu-Flex interface.
The command can be entered more than once to map multiple NRI ranges to same SGSN point code.
It is possible to configure multiple ranges to more than one SGSN however this configuration is required only when the PS core network is configured as Multi-Operator Core Network (MOCN).
When the PS core network is not MOCN and one range is mapped to more than one SGSN then SGSN is selected randomly in a non-predictable manner.
Example
The following command maps the NRI range from 101 to 201 with SGSN point code 1.2.3:
map nri range 101 to 201 point-code 1.2.3
The following command maps the NRI range from 301 to 399 with SGSN point code 1.2.3:
map nri range 301 to 399 point-code 1.2.3
The following command removes all NRI range matching entries between 301 to 399 from the configuration:
no map nri range 301 to 399
 
nri length
This command configures the network resource identifier (NRI) length in bits to identify a specific SGSN serving in a pooled area and at least one NRI value has to be assigned to an SGSN serving in a pool. The NRI is coded inside of the temporary mobile subscriber identity (TMSI), located within bits 14 to 23 with an variable length between 0 and 10 bits. Operator needs to set this NRI length to indicates the number of bits that shall be used for the NRI field to set the parameters for Iu-Flex (SGSN pooling) functionality.
Product
HNB-GW
Privilege
Security Administrator, Administrator
Syntax
nri length nri_value
default nri length
default
Sets the NRI length to default value of 0 and disables the Iu-Flex (SGSN pooling) functionality.
nri length nri_length
Default: 0
Specifies the number of bits to be used in the P-TMSI, bits 23 to 18. to define the network resource identifier (NRI). The NRI length configuration also sets the maximum size of the pool. If not configured, the NRI length is of zero length.
length must be an integer from 1 to 10 to identify the number of bits.
When a non-zero value is configured the PS network is considered to be a pool.
Usage
Use this command to enable the Iu-Flex functionality on HNB-GW. This command identifies a unique SGSN serving a pooled area for Iu-Flex functionality and at least one NRI value has to assigned to an SGSN serving in a pool. It performs SGSN pooling/offloading scenario over Iu-Flex interface. The NRI is stored in the bits 14 to 23 of TMSI. The HNB-GW uses a portion of this NRI to set the parameters for Iu-Flex (SGSN pooling) functionality.
If more than one NRI is configured, the HNB-GW service does round-robin between the available NRIs when new subscriber(s) (re)connect.
This command must be used in conjunction with null nri command to configured SGSN pooling/offloading over Iu-Flex interface.
Example
The following command sets the HNB-GW to use bit length as 6 to derive the values from NRI field (stored in the bits 14 to 23 of TMSI) to set the parameters for Iu-Flex (SGSN pooling) functionality:
nri length 6
null-nri
This command configures the null NRI for load redistribution in Iu-Flex functinality support. The NRI value defined with this command must be unique across the pool areas. This null-NRI is used by HNB-GW for load redistribution during SGSN offloading.
Product

Privilege
Security Administrator, Administrator
Syntax
null-nri null_nri_value
no null-nri null_nri_value
no
Disables/removes the configured null-NRI value used for SGSN offloading procedure.
null_nri_value
Indicates null-NRI value to be used by HNB-GW for load re-distribution during SGSN offloading.
null_nri_value must be an integer between 0 through 1023. Without MOCN configuration this value can be entered only once.
In case of MOCN a unique null-NRI must be assigned to each MOCN operator identify by its PLMN-id (MCC+MNC).
A 0 (zero) value configured as null-NRI indicates the keyword is not to be used. There is no default value for this parameter.
Usage
Use this command to identify the SGSN by HNB-GW to be used for load redistribution during SGSN offloading over Iu-Flex interface.
There is one unique null-NRI in a PLMN supporting pool functionality.
Without MOCN configuration this command can be entered only once. In case of MOCN a unique null-NRI must be assigned to each MOCN operator identify by its PLMN-id (MCC+MNC).
Example
The following command sets the null-NRI as 1001 to be used by HNB-GW for load redistribution during SGSN offloading:
null-nri 1001
