Syntax

Syntax Description

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 Guidelines

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.

Executes all show commands while in Configuration mode.

do show

Usage Guidelines

Use this command to run all Exec mode show commands while in Configuration mode. It is not necessary to exit the Config mode to run a show command.

The pipe character | is only available if the command is valid in the Exec mode.

Caution

There are some Exec mode show commands which are too resource intensive to run from Config mode. These include: do show support collection, do show support details, do show support record and do show support summary. If there is a restriction on a specific show command, the following error message is displayed: Failure: Cannot execute 'do show support' command from Config mode.

Exits the current configuration mode and returns to the Exec mode.

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).

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 Guidelines

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.

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.

release-compliance release-8

Enables the sending of EPS information in the UGL Request message to the HLR. This setting sets the 3GPP release compliance to Release 8 and above.

no release-compliance

Disables the sending of EPS information in the UGL Request message to the HLR. This command sets the 3GPP release compliance setting to Pre-release 8. This is the default setting.

Usage Guidelines

Use this command to enable or disable the sending of EPS information in the UGL Request message to the HLR.

Operators can use the show map-service all command to view the current 3GPP release compliance setting.
