SGSN APN Policy Configuration Mode Commands


SGSN APN Policy Configuration Mode Commands
 
 
The SGSN APN Policy configuration mode provides the commands to configure the access point name (APN) parameters specific to a particular SGSN operator policy.
 
Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
 
address-resolution-mode
Identify the address resolution mode for this SGSN APN policy.
Product
SGSN
Privilege
Security Administrator, Administrator
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
Default: Enabled
This keyword instructs the system to first attempt DNS resolution. If this fails, then the system is to use locally configured addresses, if available.
local
Default: Disabled
This keyword instructs the system not to use DNS query and to only use locally configured addresses.
Usage
Use this command to specify the DNS query or local address resolution for this SGSN APN policy.
Example
The following command sets the address resolution mode to attempt the DNS resolution first and if failed attempt to use available local address:
address-resolution-mode fallback-for-dns
 
cc
This command provides the configurables to define the charging characteristics for this SGSN APN policy.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
cc { local-value-for-scdrs behavior bit_value profile index_bit | prefer { hlr-value-for-scdrs | local-value-for-scdrs } }
remove cc { local-value-for-scdrs | prefer }
remove
Removes the charging characteristics configuration for this APN policy.
local-value-for-scdrs behavior bit_value profile index_bit
Defaults:bit_value = 0x0; index_bit = 8
This keyword sets the SGSN APN policy to configure the value of the behavior bits and profile index for the charging characteristics for S-CDRs locally, when the HLR does not provide values for this.
If the HLR provides the charging characteristics with behavior bits and profile index and operator want to ignore it, then specify 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 value from 1 to 15.
Some of the index values are predefined according to 3GPP standard:
prefer { hlr-value-for-scdrs | local-value-for-scdrs }
Default: hlr-value-for-scdrs
Specifies preference for using charging characteristics settings received from HLR or set by SGSN locally.
hlr-value-for-scdrs: Sets the operator policy to use charging characteristics settings received from HLR for S-CDRs. This is the default preference.
local-value-for-scdrs: Sets the operator policy to use charging characteristics settings from SGSN only for S-CDRs..
Usage
Use this command to set the APN policy behavior in operator policy to use charging characteristic for S-CDRs either from HLR or locally from SGSN.
The charging characteristics parameters are configurable from SGSN Operator Policy Configuration mode too. For generation of M-CDRs the parameters configured in SGSN Operator Policy Configuration mode will prevail but for generation of S-CDRs the parameters configured in this SGSN APN Policy Configuration mode will prevail.
Example
The following command configures the APN policy not to use charging characteristics setting received from HLR for S-CDR generation.
cc prefer hlr-value-for-scdrs

gateway-address
Configures the address of the gateway GPRS support node (GGSN) with priority to activate the GGSN. It also provides the load balancing through weight for specific GGSN address in this APN policy.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
gateway-address ip_address { priority priority | weight weight }
no gateway-address ip_address
no
Removes the preconfigured/defined GGSN address from this APN policy.
ip_address
Specifies the IP address for the GGSN in standard IPv4 or IPv6 notation.
priority priority
Specify the priority for the configured GGSN address for SGSN address selection. If one GGSN fails to respond, the next priority level GGSN is selected.
priority is an integer from 1 to 100 to assign a priority to the GGSN IP address. Note that the lower the integer, the higher the priority so that 1 is the highest priority.
weight weight
Specifies the weight (importance) assigned to a GGSN for load balancing.
weight is an integer from 1 to 100 to give a weight to the GGSN IP address.
If a weight is assigned to an address for that APN, 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% ot the activation requests for this APN will go to GGSN1 and 70% of the requests will go to GGSN2. Also note, the sum of the weights does not need to be 100. The calculation of weight percentiles is carried out proportionally; so the following configuration will also yeild the same 30% - 70% results:
GGSN1 172.16.130.1 weight 6 and GGSN2 172.16.130.3 weight 14
Usage
Use this command to provide a priority and load balancing in GGSN selection through APN policy. Note that keyword priority and weight can not be used simultaneously in one APN policy. A maximum of 16 GGSN address can be configured with this command in an APN policy..
Example
gateway-address 123.123.123.1 priority 2
 
gtp
This command enables (by adding a configuration statement) or disables (by removing the configuration statement) the GTPC private extension. This command is available in releases 9.0 and higher.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
gtp private-extension loss-of-radio-coverage send-to-ggsn [ send-to-peer-sgsn ]
remove gtp private-extension loss-of-radio-coverage send-to-ggsn [ send-to-peer-sgsn ]
remove
Including this keyword ,as part of the command, disables the inclusion of the GTPC private extension, thereby disabling the Overcharging Protection feature.
private-extension
This keyword is required as part of the gtp command to instruct 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 extension are only understood by a GGSN with an Overcharging Protection license.
loss-of-radio-coverage send-to-ggsn
This keyword set is required as part of the gtp command to instruct the SGSN to forward the private extension ‘flag’ to the GGSN in the event of 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 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, then 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 Overview chapter of the SGSN Administration Guide for functional 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 loss-of-radio-coverage send-to-ggsn

Important: Command and keyword names have changed. prefer has become prefer-as-cap and hlr has become hlr-subscription. These changes will not impact configuration generated with earlier releases as the keywords are aliases for the previous names.
remove
Removes previous configuration changes and resets the default.
both-hlr-and-local
This keyword instructs the SGSN to use, as the capping value during session establishment, the lower of either the locally configured QoS bit rate or the HLR subscription.
hlr-subscription
Default.
Instructs the SGSN to take QoS bit rates from the HLR configuration and use HLR rate as the capping value for session establishment.
local
Instructs the SGSN to take QoS bit rate from the local configuration and use it for for session establishment.
Usage
Use this command to instruct the SGSN to take QoS configuration as the bit rate for session establishment.
Example
Following command specifies use of the bit rate in subscription at the HLR:
qos prefer-as-cap hlr-subscription hlr
Instruct the SGSN to cap the bit rate with the lower rate of the two configurations, HLR or local:
qos prefer-as-cap both-hlr-and-local
 
qos rate-limit direction
Configure the parameters and actions governing the subscriber traffic flow if it violates or exceeds configured peak or committed data rates.
This command can be entered multiple times to specify different combinations of traffic direction and class. If this command is not configured at all, the GGSN does not perform traffic policing or QoS negotiation with the SGSN (i.e. it accepts all of the SGSN-provided values for the PDP context.
Additional information on the QoS traffic policing functionality is located in the System Enhanced Feature Configuration Guide.
Important: This command should be used in conjunction with the max-contexts command to limit the maximum possible bandwidth consumption by the APN.

remove qos rate-limit direction { downlink | uplink } [ class { background | conversational | interactive traffic_priority | streaming } ]
remove
Disables the QoS data rate limit configuration for the APN policy.
Important: If no Qos Profile is configured, the system’s default behavior is to use the information provided by the SGSN.
downlink | uplink
Apply the limits and actions configured with the other keywords to the selected link:
downlink - This is the direction from GGSN to MS. (from Gn to Iu/Gb).
uplink - This is the direction from MS to GGSN (from Iu/Gb to Gn).
burst-size [ bytes | auto-readjust [ duration seconds ] ]
Default: See the table of class default values in the Usage section below.
The peak burst size allowed. System measurements for this value exclude the GTP and outer packet headers. Supported options include:
bytes : Must be an integer from 1 through 6000000.
Important: It is recommended that the minimum value of this parameter be configured to the greater of the following two values: (1) 3 times greater than packet MTU for the subscriber connection, or (2) 3 seconds worth of token accumulation within the “bucket” for the configured peak-data-rate. In addition, if the committed-data-rate parameter is specified, the burst-size is applied to both the committed and peak rates.
auto-readjust : This keyword enables dynamic burst-size calculation, for traffic policing, at the time PDP Activation/Modification is negotiated using QoS maximum bit-rates and guaranteed bit-rates.
duration seconds : Must be an integer from 1 to 30. 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.
class { background | conversational | interactive traffic_priority | streaming }
Apply the specified limits and actions to PDP contexts of the specified UMTS traffic class. The following classes are supported:
background : Specifies the QOS for traffic patterns in which the data transfer is not time-critical (for example email exchange). This traffic pattern should be the lowest QOS.
conversational : Specifies the QOS for traffic patterns in which there is an constant flow of packets in each direction, upstream and downstream. This traffic pattern should be the highest QOS.
interactive traffic_priority : Specifies the QOS for traffic patterns in which there is an intermittent flow of packets in each direction, upstream and downstream. This traffic pattern should be a higher QOS than the background pattern, but not as high as that for the streaming pattern. traffic_priority is the 3GPP traffic handling priority and can be an integer 1,2 or 3.
streaming : Specifies the QOS for traffic patterns in which there is a constant flow of data in one direction, either upstream or downstream. This traffic pattern should be a higher QOS than the interactive pattern, but not as high as that for the conversational pattern.
Important: 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
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 : Drop the packet
lower-ip-precedence : Transmit the packet after lowering the IP precedence
transmit : Transmit the packet
+
This symbol indicates that the keywords can be entered multiple times within a single command.
Usage
This command configures the APN’s quality of service (QoS) data rate shaping through traffic policing. Configured actions prevent subscriber flow exceeding or violating configured peak or committed data rate limits.
Important: If either exceed action or violate action is set to “lower-ip-precedence”, this command may override the configuration of the ip qos-dscp command in the GGSN service configuration mode for packets from the GGSN to the SGSN. In addition, the GGSN service ip qos-dscp command configuration can override this APN setting for packets from the GGSN to the Internet.
Important: If a subscribed traffic class is received, the system changes the class to background and sets the following parameters: The uplink and downlink guaranteed data rates are set to 0. If the received uplink or downlink data rates are 0 and traffic policing is disabled, the default of 64 kbps is used. When enabled, the APN configured values are used. If the configured value for downlink max data rate is larger than can fit in an R4 QoS profile, the default of 64 kbps is used. If either the received uplink or downlink max data rates is non-zero, traffic policing is employed if enabled for the “Background” class. The received values are used for responses when traffic policing is disabled.
Example
The following command lowers the IP precedence when the committed-data-rate and the peak-data-rate are violated in uplink direction:
qos rate-limit direction uplink violate-action lower-ip-precedence
The following command buffers the excess user packets when the subscriber traffic violates the configured peak or committed data-rate bps in uplink direction. Once the peak/committed data rate for that subscriber goes below the configured limit it transmit them. It also transmits them if buffer memory is full:
qos rate-limit direction uplink violate-action shape transmit-when-buffer-full

class
Configure allocation retention priority for specific QoS traffic classes. Include one or more of the following class options:
background - background class of service
conversational - conversational class of service
interactive - interactive class of service
streaming - streaming class of service
Default values will be included in the configuration for any class configuration not specified.
qualifying options
For each of the class options, the configuration must include one or more of the following qualifying options:
priority - smallest number is the highest priority. Value must be an integer from 1 to 15
When entering more than one option, we recommend that you do it in the order in which they are listed.
+
This symbol indicates that the keywords can be entered multiple times within a single command.
Usage
Use this command to configure values for the allocation/retention priority (ARP) IE in the radio access bearer (RAB) assignment request message for RANAP that occurs during RAB setup.
This command can be used multiple times to define multiple priorities, with different combinations of subscription-priority and class.
If the HLR returns a matching value for the subscribed ARP for the desired traffic class, then the SGSN includes the configured qualifying options for the ARP IE in the RANAP message.
If there is no matching configuration, the SGSN includes the following default values for the traffic class (tc) within the ARP IE:
priority-level = (subscribed-value * 3) + 3
pre-emption-capability = may-trigger-pre-emption
pre-emption-vulnerability = pre-emptable
queuing-allowed = yes
priority-level = (subscribed-value * 3) + 3
