APN Remap Table Configuration Mode


Important

Beginning with Release 16 for SGSN only, an APN Remap Table associated with an IMEI profile overrides a remap table associated with an operator policy. This means activation will be rejected if a local default APN configured, in an APN Remap Table associated with an IMEI profile, cannot be used. This will occur even if a valid local default APN is available in an APN Remap Table associated with an operator policy.


A maximum of 1,000 APN remap tables are supported, and each APN remap table supports a maximum of 100 APN remap entries. Multiple tables can be defined and stored but an operator policy and/or IMEI profile each only support association with a single (one) table per policy/profile configuration. The APN remap table associated with an IMEI profile will be used in IMEI override scenarios.

Mode

APN Remap Table Configuration mode provides the commands to configure parameters for multiple features related to Access Point Name (APN) handling, such as: Default APN, APN Remap, and Wildcard APN. APN remap table is a key element of the Operator Policy feature and a table is not usable (valid) until it has been associated with an operator policy (see the Operator Policy Configuration Mode Commands) or an IMEI profile (see the IMEI Profile Configuration Mode Commands).

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 { new-ni new_apn_net_id | value-for-ni-wc new_apn_net_id { new-oi new_apn_op_id | value-for-oi-mcc mcc | value-for-oi-mnc mnc } [ orig-apn ] + }

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 .

The following options can be configured:

  • 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


Important

Entries in the APN remap table are only valid if the table is associated with an operator policy. The same table can then be associated with an IMEI profile as IMEI-specific remap entries are not supported.

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

  • a "new" APN network identifier (NI) can be mapped to override an "old" APN network identifier (NI) or an "old" APN operator identifier (OI)

  • a "new" APN operator identifier (OI) can be mapped to override an "old" APN network identifier (NI) or an "old" APN operator identifier (OI)

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.

Example

A one-to-one APN NI remap entry is illustrated by:
apn-remap network-identifier 123abc.com new-ni 333CBC.com    
Create an entry with a wildcard so that part of an incoming APN NI will be replaced - for example, incoming xyzabcpqr.com becomes xyzinternet2pqr.com .
apn-remap network-identifier xyz*pqr.com value-for-ni-wc internet2  
Replace any incoming APN NI with a new APN NI.
apn-remap network-identifier * value-for-ni-wc newnet.com

Usage Guidelines


Important

Entries in the APN remap table are only valid if the table is associated with an operator policy. The same table can then be associated with an IMEI profile as IMEI-specific remap entries are not supported.

This command enables MME to remap all UE requested APNs containing non-3GPP characters to the configured new-ni APN.

This CLI is applied only if the UE sessions are not rejected by the new configuration options policy attach reject-non3gpp-char-apn and policy pdn-connect reject-non3gpp-char-apn under the mme-service. If the UE requested APN contains non-3GPP characters and the apn-remap non3gpp-char-apn new-ni CLI command is configured, then this CLI takes precedence over any other matching criterion for APN remapping.

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.

first-in-subscription [ orig-apn ]

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 MME, if the default APN in the subscription data matches the requested pdn-type, then the default APN is used. Otherwise, the first record from the list of records (apn-list) sent from the HSS with PDP type matching the UE-requested PDP type is selected. The apn-list is sorted according to apn-name.

orig-apn : Enables MME to send the original APN (UE requested APN) in the ATTACH_ACCEPT or ACTIVATE_DEFAULT_BEARER_REQUEST message to the UE. This is an optional keyword.

If this keyword is not configured, then re-mapped APN is sent back to UE.

lowest-context-id [ orig-apn ]

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.

orig-apn : Enables MME to send the original APN (UE requested APN) in the ATTACH_ACCEPT or ACTIVATE_DEFAULT_BEARER_REQUEST message to the UE. This is an optional keyword.

If this keyword is not configured, then remapped APN is sent back to UE.

network-identifier apn_net_id

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

In 21.4 and later releases, this keyword is enhanced to support S4-SGSN.

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

SGSN only.

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

prefer-single-subscription

SGSN only.

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

reject-blank-apn

SGSN only.

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

require-dns-fail-wildcard [ orig-apn ]

MME only.

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

orig-apn : Enables MME to send the original APN (UE requested APN) in the ATTACH_ACCEPT or ACTIVATE_DEFAULT_BEARER_REQUEST message to the UE. This is an optional keyword.

If this keyword is not configured, then remapped APN is sent back to UE.

In 18.2 and later releases: The require-dns-fail-wildcard keyword is also supported by the MME.

In releases prior to 21.4: The require-dns-fail-wildcard keyword is not supported for S4-SGSN.

In 21.4 and later releases: The require-dns-fail-wildcard keyword is supported for S4-SGSN.

require-subscription-apn network-identifier apn_net_id

SGSN only.

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:

  • override a requested APN when the HSS/HLR does not have the requested APN in the subscription profile.

  • provide a viable APN if APN selection fails because there was no "requested APN" and wildcard subscription was not an option.

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

  • the wildcard-apn command is configured, (requirement only for SGSN)

  • a wildcard subscription is present,

  • the require-dns-fail-wildcard keyword is included with the apn-selection-default command then the configured default APN will be used when the DNS query is retried.

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.


Important

For SGSN ONLY - Beginning with Release 16, customers already using an APN remap table that is associated with an IMEI profile will have to change the existing configuration to enable the default APN remapping associated with an operator policy rather than the one associated with an IMEI profile. For example, if an existing configuration forced all matching IMEI in a defined IMEI range to use xxx.net APN, the configuration needs to be changed to an APN remap table configuration similar to what is shown below:
Old APN remap table associated with an IMEI profile:
apn-selection-default network-identifier  xxx.net  
For a configuration to accomplish the same remapping function, change the APN remap table associated with an IMEI profile to the following:
apn-remap network-identifier * new-ni  xxx.net 

Important

For SGSN ONLY - With Release 16, an APN remap table associated with an IMEI profile overrides a remap table associated with an operator policy. This means activation will be rejected if a local default APN configured, in an APN remap table associated with an IMEI profile, cannot be used. This will occur even if a valid local default APN is available in an APN remap table associated with an operator policy.
For SGSN ONLY - Beginning with Release 16, the following sample configuration will enable the operator to bypass APN remapping for a specific IMEI range:
config  
   operator-policy name  OpPol1 
      associate call-control-profile  OpPol1CCprof1 
      associate apn-remap-table  RemapOpPol1 
      imei-range first  start_imei last  ending_imei [ sv  IMEI_sv ] imei-profile name  IMEIprof1 
      exit  
   imei-profile name  IMEIprof1 
      associate apn-remap-table remap IMEIprof1  
      exit  
   apn-remap-table   remapIMEIprof1 
      exit  
   apn-remap-table   RemapOpPol1 
      apn-selection-default network-identifier  NewAPN.net 
      end  

Example

The following command enables the default APN feature for APN HomeNet1 in an APN remap table associated with an operator policy:
apn-selection-default network-identifier HomeNet1  
For SGSN only - Beginning with Release 16, if the APN remap table is associated with an IMEI profile, for a configuration to accomplish the same remapping function as noted in the sample above, then use syntax similar to the following:
apn-remap network-identifier * new-ni   xxx.net 
The following command, in an APN remap table associated with an operator policy, enables use of a default APN selected on the basis of lowest context-ID if the APN is not contained within the subscription:
apn-selection-default lowest-context-id  
The following command enables use of a default APN if the DNS query fails:
apn-selection-default network-identifier HomeNet1 require-dns-fail-wildcard

  • ipv6 - for an IPv6 context

  • ppp - for a PPP context

network-identifier apn_net_id

Identifies one of the APN network identifiers specified via the apn command in the Operator Policy configuration mode.

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

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:

  • the UE requested a PDP type of IPv4v6

  • the UE did not request any specific APN

  • the subscription includes wildcard APN with PDP type as IPv4v6.


Important

Wildcard APN feature configuration is only valid if the APN remap table is associated with at least one operator policy. The same table can then be associated with an IMEI profile as IMEI-specific Wildcard APN is not supported.


Example

Use this command to enable an APN wildcard for PDP type IPv4 and NI homer1 :
