> HLR Configuration Mode Commands
> The HLR Configuration Mode provides the commands and parameters to configure the home location register (HLR) node that is the database containing the subscriber profile and connection information for a specific GPRS/UMTS core network.
> In this mode, your prompt will look similar to:
> [<context_name>]hostname(config-map-service-<svr_name>-hlr)#
> The HLR Configuration Mode is a sub-mode derived from the MAP Configuration Mode which controls the MAP service configuration. It is the MAP service that provides the application-layer protocol support used to connect the HLR to other nodes in the network such as the SGSN.
> When the mode is accessed, the command line will appear similar to
> [<ctx_name>]asr5000(config-map-service-<service_name>-hlr)#
> Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
> acn-version-retention
> This command configures the ACN version retention method.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> acn-version-retention { per-imsi-prefix | per-subscriber }
> default acn-version-retention
> default
> Returns the configuration to the default value: retains the version information per IMSI prefix.
> per-imsi-prefix
> Retain ACN version information, for communication with the HLR, on a per IMSI prefix basis.
> per-subscriber
> Retain ACN version information, for communication with the HLR, on a per buscriber basis.
> Usage
> By default, the SGSN sends ACN version 3 SAI (service area identity) to the HLR. If the SGSN receives an error message indicating that the HLR does not support that version, then the SGSN tries again with an ACN version 2 SAI. Next time the SGSN communicates with that HLR, it retains that version information and version persists based on the IMSI prefix.
> Use this command to enable the SGSN to retain version according to subscriber.
> Example
> Configure the SGSN to retain version information according to the IMSI prefix:
> default acn-version-retention
> end
> Exits the current configuration mode and returns to the Exec mode.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> end
> Usage
> Return to the Exec mode.
> exit
> Exits the current configuration mode and returns to the MAP Service configuration mode.

> Security Administrator, Administrator
> Syntax
> exit
> Usage
> Return to the MAP Service configuration mode.
> imsi
> This command sets up IMSI (International Mobile Subscriber Identity) -based configuration. The IMSI prefix includes the nobile country code (MCC) and the mobile network code (MNC).
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> [ no ] imsi { any | starts-with prefix_number } { imsi [ sgsn-source-address-format point-code-ssn [ source-ssn ssn ] | isdn isdn_number | mobile-global-title mgt_number [ max-gt-address-len max_gt_address ] | point-code pt-code } }
> no
> Removes the imsi-prefix definition from the configuration.
> any
> Configures acceptance of any IMSI prefix.
> start-with prefix_number
> Selects IMSI prefix-based routing.
> prefix_number is a string of up to 15 integers.
> imsi
> Enables configurable default behavior for routing.
> Entering imsi with the any keyword preserves the default behavior and the E.212 address is used as a destination address and the MAP request will be sent towards the HLR.
> If this keyword is not used with the any keyword, then the MAP request will be rejected.
> isdn isdn_number
> Defines the E.164 number of the HLR.
> isdn_number is a string of integers, up to 15.
> mobile-global-title mgt_number [ max-gt-address-len max_gt_address_length ]
> Defines the mobile global title address that the MCC/MNC portion of the IMSI will be converted to. If the maximum GT address length is specified (optional) and if the length of the MGT string is greater than defined, then the least significant digits will be omitted.
> mgt_number is a string of digits, up to 18 digits in length.
> max_gt_address is an integer from 1 to 32.
> point-code pt-code source-ssn ssn
> Defines the point code for the HLR.
> pt-code is a string of digits, up to 11; SS7 format preferred.
> sgsn-source-address-format point-code-ssn
> Selects HLR call process according to SCCP calling party address of the SGSN. This will be filled at MAP level, including the ITU point code address.
> source-ssn ssn
> Defines the SSN of the source that will be used for the call filtering.
> ssn: Must be an integer from 1 to 255.
> Usage
> Routing will be done according to IMSI parameters configured with this command or according to the mobile global title address (replacing the MCC/MNC portion of the IMSI) is so specified.
> Example
> imsi starts-with 3 isdn 123456789 sgsn-source-address-form at point-code-ssn
> policy routing
> This command configures the policy for the routing of MAP messages. If this command is not configured or disabled (with the default keyword), then routing is done according to the configuration of the IMSI parameters.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> policy routing { hlr-isdn | ms-isdn }
> default policy routing
> no policy routing
> default
> Resets the policy routing to the system default, disabled.
> no
> Removes the policy routing configuration from the system.
> hlr-isdn
> Selects HLR-ISDN based routing.
> ms-isdn
> Selects mobile station (MS)-ISDN based routing.
> Usage
> Use this command to set the policy for routing MAP messages.
> Example
> policy routing hlr-isdn
