no

Deletes the specified APN remap entry from the APN remap table.

network-identifier apn_net_id

Identifies the "old" APN network identifier that is being mapped for replacement.

apn_net_id is a string of 1 to 62 characters, including digits, letters, dots (.) and dashes (-). Additionally, one wildcard character ( * ) can be included anywhere within the string.

new-ni new_apn_net_id

Identifies the new (target) network identifier to use when no wildcard character is included in the "old" APN network identifier.

new_apn_net_id is a string of 1 to 62 characters, including digits, letters, dots (.) and dashes (-).

value-for-ni-wc new_apn_net_id

Identifies the information to replace the wildcard in the new APN network identifier when a wildcard character is included in the "old" APN network identifier.

new_apn_net_id is an alphanumeric string of characters, including dots (.) and dashes (-). This string replaces the wildcard (*) specified in the apn_net_id. The two strings together must not exceed 62 characters.

operator-identifier apn_op_id

Identifies the "old" APN operator identifier that is being mapped for replacement.

apn_op_id is a string of 1 to 18 characters including digits, letters, and dots (.). The entry must be in the following format, where # represents a digit: MNC###.MCC###.GPRS.

Optionally, either one or two wildcard characters ( * ) can be entered. Wildcard characters can be used in place of one # or three # -- for example MNC12*.MCC*.GPRS.

new-oi new_apn_op_id

Identifies the new (target) operator identifier to use when no wildcard character is included in the "old" APN operator identifier.

new_apn_op_id is a string of 1 to 18 characters including digits, letters, and dots (.). The entry must be in the following format, where # represents a digit: MNC###.MCC###.GPRS.

value-for-oi-mcc mcc

Identifies the information to replace the wildcard in the new APN operator identifier when a wildcard character is included in the MCC portion of the "old" APN operator identifier; for example MNC###.MCC*.GPRS.

value-for-oi-mnc mnc

Identifies the information to replace the wildcard in the new APN operator identifier when a wildcard character is included in the MNC portion of the "old" APN operator identifier; for example MNC*.MCC###.GPRS.

Usage Guidelines

This command defines mapping entries in the APN remap table which supports a range of APN overrides. Mapping can be done one-to-one:

Mapping can also be done with wildcards in the "old" APN entry mapped to wildcard replacements to dynamically create "new" APN network/operator identifiers.

Related Commands: APN override can also be based on charging characteristics. This type of override mapping is defined with the cc command, also part of this configuration mode.

Enables and configures or disables the Default APN feature for use when the normal APN selection process fails.

no

Delete the configuration statement and disable the default APN feature.

first-in-subscription

Specifies that the first APN in the subscription record matching the requested PDN type is used as the default APN. This applies when normal APN selection fails and if the UE APN is absent and the defined default APN is not a match.

For the SGSN, "first-in-subscription" means the first record from the list of records sent from the HLR (in the same order) with PDP type matching the requested PDP type. With this configuration, if the first record is a wildcard APN it is expected that the wildcard APN be configured. If not, the activation will be rejected.

For the MME, "first-in-subscription" means the first record from the list of records (apn-list) sent from the HSS with PDP type matching the UE-requested PDP type. The apn-list is sorted according to apn-name.

lowest-context-id

Specifies that the subscription APN with the lowest context-ID in the subscription record matching the PDN type is used as the default APN when normal APN selection fails.

With this configuration, if the record with the lowest context-ID is a wildcard APN, then it is expected that the wildcard APN has already been configured. If not, the activation will be rejected.

If both apn-selection-default lowest-context-id and apn-selection-default first-in-subscription options are configured, whichever command was executed (configured) first will be the behavior used.

Starting with Release 14.0, MME also supports use of this keyword.

network-identifier apn_net_id

Specifies the network identifier will be used as the default APN name as a string of 1 to 62 characters, including digits, letters, dots (.) and dashes (-).

Any of the following optional keywords can be used with network-identifier as qualifications.

fallback-apn network-identifier apn_net_id

SGSN only.

Specifies a dummy APN to be used when the default APN is not present in the subscription so that the activation does not fail. With this keyword configured, the context is activated with a dummy APN and the GGSN displays a static page for this APN, instructing the subscriber to subscribe for appropriate services.

apn_net_id is a string of 1 to 62 characters, including letters, digits, dots (.) and dashes (-).

fallback-to-first-in-subscription

Uses the APN from the first subscription record when the configured default APN is not available.

prefer-single-subscription

Uses the APN from the subscription record if it is the only record available and normal APN selection fails.

reject-blank-apn

Disables use of the default APN if a blank APN is received.

require-dns-fail-wildcard

Enables the default APN to be used if the DNS query fails with the requested APN.

Starting with Release 18.2, this keyword is also supported by the MME.

require-subscription-apn network-identifier apn_net_id

If defined, this APN name must also be included in the subscription data for the default APN feature to function.

apn_net_id is a string of 1 to 62 characters, including letters, digits, dots (.) and dashes (-).

Usage Guidelines

The default APN feature will be used in error situations when the MME or the SGSN cannot select a valid APN via the normal APN selection process. Within an operator policy, an APN remap table with a default APN can be configured for the MME/SGSN to:

The default APN feature can also be used in the event of a DNS query failure with the selected APN, if:

In all of the instances outlined above, the MME/SGSN can provide the default APN as an alternate behavior to ensure that PDP context activation is successful.

behavior bit_value

Specifies the value for the charging characteristic behavior bit.

bit_value is a hex value from 0x0 to 0xFFF.

profile index_bit

Specifies the index for the charging characteristic profile.

index_bit is an integer from 1 through 15.

Some of the index values are predefined according to 3GPP standards:

apn-remap network-identifier apn_net_id

Identifies the "old" APN network identifier that is being mapped for replacement.

apn_net_id is a string of 1 to 62 characters, including letters, digits, dots (.) and dashes (-).

new-ni new_apn_net_id

Identifies the "new" APN network identifier that is being mapped to.

new_apn_net_id is a string of 1 to 62 characters, including letters, digits, dots (.) and dashes (-).

Usage Guidelines

Use this command to enable APN remapping only when the charging characteristic value in the subscription record associated with the requested APN matches the value configured for the new-ni.

The new APN NI must be part of the subscription data so that the charging characteristic associated with the new APN NI will be used for activating the context. If there is not one associated, then the general charging characteristic will be used.

Usage Guidelines

This command is used to define a wildcard APN with the type of PDP context and the APN's network identifier (NI). This wildcard APN would be used when an APN is not identified.

The command should be repeated per PDP type, as needed, to enable wildcard APN for two or more of the PDP types.

The wildcard APN configured with the dual PDP IPv4v6 context will be used in the following scenarios:
