# APN Profile Configuration Mode

The APN Profile configuration mode defines a set of parameters controlling the SGSN or MME behavior when a specific APN is received or no APN is received in a Request. An APN profile is a key element in the Operator Policy feature and an APN profile is not used or valid unless it is associated with an APN and this association is specified in an operator policy (see the Operator Policy Configuration Mode Commands chapter elsewhere in this guide).

Essentially, an APN profile is a template that consists of a set of APN-specific commands that may be applicable to one or more APNs. When a subscriber requests an APN that has been identified in a selected operator policy, the set of commands in the associated APN profile will be applied. The same APN profile can be associated with multiple APNs and multiple operator policies.

The SGSN and the MME each support a total of 1,000 APN profile configurations per SGSN/MME; up to 50 APN profiles can be associated with a single operator policy. For additional SGSN limit information, refer to the Engineering Rules appendix in the SGSN Administration Guide.
When this mode is accessed, the command prompt should resemble:

    [local]asr5000(apn-profile-<profile_name>)#

IMPORTANT:

The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
address-resolution-mode

Identifies the address resolution mode for this APN profile. This command is specific to the SGSN.
Platform:

Syntax

    address-resolution-mode { fallback-for-dns | local }default address-resolution-mode

default

Resets the configuration to the default value; i.e. fallback-for-dns.
fallback-for-dns

Instructs the system to try DNS resolution. If the DNS query fails, the SGSN will use locally configured addresses, if they have been configured.

Default: enabled
local

Instructs the system to only use locally configured addresses and not to use DNS query.

Default: disabled
Usage:

Use this command to specify the DNS query or local address resolution for this APN profile.
Example:
The following command sets the address resolution mode to use local addresses only if the DNS query fails:

    address-resolution-mode
    fallback-for-dns

apn-resolve-dns-query

Command enables the SGSN to send Straightforward Name Authority Pointer (SNAPTR) type DNS query for APN resolution on a per APN basis.

Syntax

    apn-resolve-dns-query
    snaptr remove apn-resolve-dns-query
    snaptr

remove

Removes the DNS SNAPTR function from the configuration.
Usage:

SNAPTR filters based on the EPC-capability of the user equipment (UE). Use this command to enable SNAPTR type DNS query for APN resolution for 3G subscribers with EPC subscription. Configuration in this mode promotes control of this feature per APN.

When this functionality is enabled, an SGSN using Gn/Gp interfaces can optionally select a PGW while activating a context if the subscriber is EPS capable. This supports EPS-based mobility if the subscriber is anchored at the PGW. At PDP Context Activation, the SGSN will use the UE capability as input to select the GGSN or PGW. SNAPTR DNS query allows for PGW resolution.

By default, this functionality is not enabled.
Example:
Enable the SGSN to select a PGW during APN resolution:

    apn-resolve-dns-query snaptr

remove

Removes the charging characteristics configuration from this APN profile.
local-value-for-scdrs behavior bit_value profile index_bit

Sets the value of the behavior bits and profile index for the charging characteristics for S-CDRs locally, when the Home Location Register (HLR) does not provide these values.

If the HLR provides the charging characteristics with behavior bits and profile index, and the operator wants to ignore what the HLR provides, then specify the prefer local-value-for-scdrs keyword with this command.

bit_value: must be a hexadecimal value between 0x0 and 0xFFF.

index_bit: must be an integer from 1 through 15.

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

- 1 for hot billing
- 2 for flat billing
- 4 for prepaid billing
- 8 for normal billing

Defaults: bit_value = 0x0; index_bit = 8
prefer { hlr-value-for-scdrs | local-value-for-scdrs }

Specify what charging characteristic settings the system will use for S-CDRs.

- hlr-value-for-scdrs: instructs the system to use charging characteristic settings received from the HLR for S-CDRs.
- local-value-for-scdrs: instructs the profile preference to only use locally configured/stored charging characteristic settings for S-CDRs.

Default: hlr-value-for-scdrs
Usage:

Use this command to specify the charging characteristic for S-CDRs -- either from the HLR or locally from the SGSN.

These charging characteristics parameters for S-CDRs and M-CDRs are also configurable in the Call-Control Profile configuration mode. When CC parameters are specified in both types of profiles, then:

- For generation of M-CDRs, the parameters configured in the Call-Control Profile configuration mode will take precedence.
- For generation of S-CDRs, the parameters configured in the APN Profile configuration mode will take precedence.

Example:
The following command configures the APN profile to instruct the SGSN not to use charging characteristic settings received from the HLR for S-CDR generation:

    cc prefer hlr-value-for-scdrs

dns-extn

Takes an offset group of digits from the MSISDN and appends the digits to the DNS query string to create a new APN intended to assist roaming subscribers to use the local GGSN.
Platform:

SGSN
Privilege:

charg-id { binary | decimal | hexadecimal }

Instructs the SGSN to take the profile index value of the charging characteristics, from the PDP subscription record (selected during APN selection) and include the profile index value in the APN name prior to sending out DNS queries. The operator can also specify the format (binary, decimal or hexadecimal) for the CC information to be included.
lac-rac

Enables the SGSN to append geographical information to the APN string that is being sent in the DNS query. This information is used during the DNS query process to select the geographically closest GGSN.
msisdn start-offset start_digits end-offset end-digits

Defines an offset group of digits from the MSISDN and appends the digits to create a new APN DNS query string that is intended to assist roaming subscribers to use the local GGSN.

- start_digits is an integer from 1 through 14 that identifies the position of the first digit in the MSISDN to start the offset.
- end-digits is an integer from 2 through 15 that identifies the position of the last digit in the MSISDN to be part of the offset.

rnc-id [ charg-id { binary | decimal | hexadecimal } ]

Instructs the SGSN to include the ID of the calling RNC in the APN DNS query string. Optionally, the profile index value of the charging characteristics can be inserted into the APN name prior to sending out DNS queries. As well, the operator can specify the format (binary, decimal or hexadecimal) for the CC information to be included.
Usage:

With this command, the APN in the DNS query string, used for querying the GGSN address, can be appended with additional information, such as

- digits from the MSISDN
- LAC/RAC info
- RNC-ID
- profile index from the charging characteristics information (SCHAR)

This additional information allows some customization of the DNS query string to facilitate selecting a specific (usually local or nearest) GGSN.

For example, roaming subscribers using a specific APN may want to be directed to a specific GGSN. This can be achieved by having an operator policy for roaming subscribers associated with an APN profile that includes a configuration specifying certain digits, from the MSISDN or geographical information from the LAC/RAC, be appended to the APN. This is then used as the DNS query string.

In addition, the operator must configure appropriate DNS entries to enforce the selection of the required GGSN. After appending the MSISDN digits to the DNS query string, the string will have the form: `ni.<digits>.mnc*.mcc*.gprs`. After appending the LAC/RAC information to the DNS query string, the string will have the form: `<apn_network_id>.racAAAA.lacBBBB.<apn_operator_id>` , where the AAAA and BBBB are Hex-coded digits (less than 4 significant digits and one or more zero (“0”) digits will be inserted to the left side of the Hex to fill the 4-digit coding).

After appending the charging characteristic (SCHAR) information, the DNS string will take the following form: `<apn_network_id>.<profile_index>.<apn_operator_id>.` The profile index in the following example has an integer value 10: `quicknet.com.uk.1010.mnc234.mcc027.gprs`.

If the RNC-ID information is configured to be a part of the APN name, and if inclusion of the profile index of the charging characteristics information is also enabled before the DNS query is sent, the profile index is included after the included RNC-ID and the DNS APN name will appear in the following form:`<apn_network_id>.<rnc_id>.<profile_index>.<apn_operator_id>`.

Once the DNS extension is defined, the selected extension is applicable when either the wildcard APN feature or the default APN feature are configured and used.

The information is appended to the DNS query and the actual APN string sent to the GGSN will not be modified in any way.
Example:
A sample MSISDN is ‘112233445566778’ and a sample APN NI (network identifier) is ‘wap98.testnetz.ca’. The following command instructs the SGSN to create a new APN with digits pulled from the MSISDN and appended to the APN:

    msisdn start-offset
    3 end-offset 9

The resulting APN DNS query string would have appended 7 digits (2233445)to the APN NI so that it would appear something like `wap98.testnetz.ca.2233445.MNC009.MCC262.GPRS`
Enable inclusion of geographical information in the APN string used for the DNS query to locate the closest GGSN:

    lac-rac

In the following example, the DNS query for a subscriber using RNC 0321 with the profile index of value 8 would appear as: `quicknet.com.uk.0321.1000.mnc234.mcc027.gprs`

Disables the GGSN address configured in this APN profile.
ip_address

Specifies the IP address for the GGSN in IPv4 dotted-decimal or IPv6 colon-separated notation.
priority priority

Specifies the priority, for the configured GGSN address, to be considered during address selection. If the highest priority GGSN fails to respond, the next priority level GGSN is selected. priority is an integer from 1 through 100. Note that the lower integer has the higher priority, so that 1 is the highest priority.
weight weight [ secondary-pool ]

Specifies the weight (preference) assigned to a GGSN to facilitate load balancing. weight is an integer from 1 to 100 where 1 is the least preferred and 100 is the most preferred.
If a weight is assigned to an address, then load balancing (of primary CPC requests) depends on the weight value. For example:

    GGSN1 172.16.130.1
    weight 30 and GGSN2 172.16.130.3 weight 70

With this configuration, 30% of the activation requests for this APN will go to GGSN1 and 70% of the requests will go to GGSN2. Also note that the sum of the weights does not need to be 100. The calculation of weight percentiles is carried out proportionately, so the following configuration will also yield the same 30% - 70% results:

    GGSN1 172.16.130.1
    weight 6 and GGSN2 172.16.130.3 weight 14

secondary-pool

This optional keyword allows the operator to enable multiple GGSN pools by assigning the GGSN to a secondary pool of GGSNs. The selection algorithm for GGSNs in a secondary pool is weight-based.
Usage:

Use this command to define priority or load balancing to be applied during GGSN selection. A maximum of 16 GGSN address can be configured for this APN profile.

Also use this command to setup GGSN pools - primary and secondary pools with up to 16 GGSNs in each pool. By default, GGSNs will always be selected from the primary pool. However, working in tandem with the ggsn-fail-retry-timer command configuration (SGTP service configuration mode) which enables the local DNS feature, some of the primary GGSNs can be temporarily blacklisted if they become unavailable or overburdened.
Example:
Set a GGSN address with a secondary priority level:

    gateway-address 123.123.123.2
    priority 2

Add a GGSN to the secondary GGSN pool and define selection weighting of 7th:

    gateway-address 198.168.138.8
    weight 7 secondary-pool

private-extension loss-of-radio-coverage send-to-ggsn

Instructs the SGSN to set a proprietary GTPC private extension (in the LORC Intimation IEs) in the event of loss of radio coverage (LORC). These private extensions are only understood by a GGSN with an Overcharging Protection license.

The mandatory loss-of-radio-coverage send-to-ggsn keyword set instructs the SGSN to forward the private extension flag to the GGSN in the event of a loss of radio coverage (LORC).
send-to-peer-sgsn

This optional keyword instructs the SGSN to also forward the LORC private extension to the peer SGSN.
Usage:

gtp private-extension is one of the two commands required to enable the Overcharging Protection feature. The second command sets the RANAP cause code in the Iu Release to enable the SGSN to detect the LORC state of the MS/UE. This second command is configured in the IuPS service and is explained in the IuPS Service Configuration Mode chapter.

When there is a loss of coverage and the Overcharging Protection feature is enabled with the gtp private-extension command, the SGSN includes the proprietary private extension in the GTP LORC Intimation IE messages. This LORC IE is also included in UPCQ, DPCQ, and SGSN Context Response GTP messages.

Refer to the SGSN Administration Guide for additional information regarding the Overcharging Protection feature.
Example:
Use the following command to have the SGSN send the GGSN the GTPC private extension in the LORC Intimation IE:

    gtp private-extension

weight weight

Specifies the weight (preference) assigned to the addressed P-GW for load balancing. weight is an integer from 1 through 100 where 1 is the least preferred and 100 is the most preferred. If no weight is specified, the P-GW address is assigned a default weight of 1.

If a weight is assigned to an address, the weights of the P-GW(s) (that are operational) are totaled, and then a weighted round-robin selection is used to distribute new primary PDP contexts (for MME) or primary CPC requests (for SGSN) among the P-GW(s) according to their weights. As with all weighted round-robin algorithms, the distribution does not look at the current distribution, but simply uses the weights to distribute new requests. For example, two P-GWs assigned weights of 70 and 30 would distribute 70% of calls to one, and 30% to the other. The sum of all weights do not need to total 100.
Usage:

Use this command to define load balancing to be applied during P-GW selection. A maximum of 16 P-GW addresses can be configured for this APN profile.

On the S4-SGSN, use this command to configure a local P-GW address for operators wishing to bypass DNS resolution of APN FQDN.

Usage:

This command defines the qualifying options (parameters) for each QoS traffic class defined for this APN profile.

IMPORTANT:

Typically this command is only used to define QoS parameters when the APN record does not exist in the subscription record.

Repeat the command as often as needed with different options to define all required QoS criteria. For example, to configure the maximum bit rate (MBR) for the downlink and uplink directions for a traffic class, this command must be used twice, specifying mbr-down once and mbr-up once.

Advantage for local mapping of MBR: some HLRs cannot be configured with high MBR values. Using the mbr-map-up and the mbr-map-down parameters allows the SGSN to be configured to treat a specific HLR value as meaning the desired high MBR value. In a case where the HLR does not support HSPA+ bit rates, but the handsets and network do, this feature allows the operator to overcome limitations on the HLR and provide HSPA+ bit rates by overwriting the provisioned HLR-QoS MBR values with SGSN-configured values. When MBR mapping is configured, if QoS is preferred as the HLR value, then the subscription QoS MBR received from the HLR is compared with the "from" value in the table. If it matches, then it is converted to the value specified by the "to" value in the table. QoS negotiation happens based on the converted value.

Advantage for QoS capping with THP and ARP: Controlling THP and ARP via Operator Policy: This functionality can differentiate home vs. roaming subscribers, and prevent visiting subscribers from receiving a high-tiered service. For example, a service provider could offer service differentiation using Ultra/Super/Standard service levels based upon QoS; this could justify charging a corporate customer more to use the Internet APN than would be charged to a consumer. This could be accomplished by controlling the traffic handling priority (THP) over the air interface, i.e. THP 1 = Ultra, THP 2 = Super and THP 3 = Standard.
Example:
Use the following command to configure the entire conversational traffic class with predefined QoS options:

    qos class conversational
    all-values

Now change the background class ARP from 3 to 2:

    qos class background
    arp 2

Invalidate the THP parameter, by removing all value from the parameter, for the interactive class:

    remove qos class interactive thp

downlink | uplink

Apply the limits and actions configured with the other keywords to the selected link:

downlink - This is the direction from the GGSN or P-GW to the MS.

uplink - This is the direction from the MS to the GGSN or the P-GW.
burst-size { auto-readjust [ duration seconds ] | bytes }

Default: See the table of class default values in the Usage section below.

This keyword specifies the peak burst size allowed. System measurements for this value exclude the GTP and outer packet headers. Supported options include:

- auto-readjust: This keyword enables dynamic burst-size calculation using negotiated peak data-rate and negotiated committed data-rate.
- duration seconds: Must be an integer from 1 to 30; default is 1. This keyword sets the number of seconds that the dynamic burst-size calculation will last. This allows the traffic to be throttled at the negotiated rates.
- bytes: Must be an integer from 1 to 6000000. This value specifies the static burst size for traffic policing. This option is present for backward compatibility.

IMPORTANT:

Use of dynamic burst size (auto-readjust) for traffic policing is recommended, rather than the static burst size.
class { background | conversational | interactive traffic_priority | streaming }

The class keyword configures the specified traffic policing actions per traffic class, or per traffic priority in the case of interactive traffic class. The following classes are supported:

- background: Specifies the traffic action for traffic patterns in which the data transfer is not time-critical (for example, email exchanges).
- conversational : Specifies the traffic policing action for traffic patterns in which there is a constant flow of packets in each direction, upstream and downstream.
- interactive traffic_priority: Specifies the traffic policing action for traffic patterns in which there is an intermittent flow of packets in each direction, upstream and downstream. traffic_priority is the 3GPP traffic handling priority and can be an integer 1,2 or 3.
- streaming: Specifies the traffic policing action for traffic patterns in which there is a constant flow of data in one direction, either upstream or downstream.

IMPORTANT:

This is an SGSN-specific feature. If this keyword is omitted, the same values are used for all classes.
exceed-action { drop | lower-ip-precedence | transmit }

Default: See the table of class default values in the Usage section below.

The action to take on the packets that exceed the committed-data-rate but do not violate the peak-data-rate. The following actions are supported:

- drop: Drop the packet
- lower-ip-precedence: Transmit the packet after lowering the ip-precedence
- transmit: Transmit the packet

gbr-qci [ committed-auto-readjust durarion seconds ]

Applies the traffic policing policy to guaranteed bitrate bearers.

committed-auto-readjust duration seconds: Must be an integer from 1 to 30. This keyword sets the number of seconds that the committed burst-size calculation will last. This allows the traffic to be throttled to the negotiated rates.

IMPORTANT:

This is an S-GW-specific feature.
non-gbr-qci [ committed-auto-readjust durarion seconds ]

Applies the traffic policing policy to non-guaranteed bitrate bearers.

committed-auto-readjust duration seconds: Must be an integer from 1 to 30. This keyword sets the number of seconds that the committed burst-size calculation will last. This allows the traffic to be throttled to the negotiated rates.

IMPORTANT:

This is an S-GW-specific feature.
violate-action { drop | lower-ip-precedence | transmit }

Default: See the table of class default values in the Usage section below.

The action to take on the packets that exceed both the committed-data-rate and the peak-data-rate. The following actions are supported:

- drop: Drops the packet
- lower-ip-precedence: Transmits the packet after lowering the IP precedence
- transmit: Transmits the packet
