Call Control Profile Configuration Mode

Call Control Profile Configuration Mode
 
Call Control Profile configuration mode defines call-handling rules which can be combined with other profiles – such as an APN profile (see the APN Profile Configuration Mode Commands chapter) – when using the Operator Policy feature. The call control profile is a key element in the Operator Policy feature and the profile is not valid until it is associated with an operator policy (see the Operator Policy Configuration Mode Commands chapter).
The MME and SGSN each support a maximum of 1,000 call control profiles; only one profile can be associated with an operator policy.
By configuring a call control profile, the operator fine tunes any desired restrictions or limitations needed to control call handling per subscriber or for a group of callers across IMSI (International Mobile Subscriber Identity) ranges.
Upon accessing this mode, the CLI prompt be similar to the following:
[local]asr5000(config-call-control-profile-<profile_name>)#
access-restriction-data
Enables the operator to assign a failure code to be included in reject messages if the attach rejection is due to access restriction data (ARD) checking in the incoming subscriber data (ISD) messages. The operator can also disable the ARD checking behavior.

no-check
Including this keyword with the command disables the ARD checking behavior.
Usage
By default, the SGSN checks access restriction data (ARD) within incoming insert subscriber data (ISD) messages. This enables operator to selectively restrict subscribers in either 3G (UTRAN) or 2G (GERAN). The SGSN ARD checking behavior occurs during the attach procedure and if a reject occurs, the SGSN sends the subscriber an Attach Reject message with a configurable failure cause code.
Example
For this call control profile, the following command disables the ARD checking function:
access-restriction-data no-check
accounting context
Defines the name of the accounting context and optionally associates a GTPP group with this call control profile.

Privilege
Security Administrator, Administrator
Syntax
accounting context ctxt_name [ gtpp group grp_name ]
remove accounting context
remove
Removes the accounting configuration from this profile’s configuration.
ctxt_name
Specifies the accounting context as an alphanumeric string of 1 through 79 characters.
gtpp group grp_name
Identifies the GTPP group, where the GTPP related parameters have been configured in the GTPP Group Configuration mode, to associate with this call control profile.
grp_name: Enter an alphanumeric string of 1 through 63 characters to identify the GTPP group created with the gtpp group command in the Context configuration mode.
Usage
This command can be used to associate a predefined GTPP server group - including all its associated configuration - with a specific call control profile. The GTPP group would have been defined with the gtpp group command (see the Context Configuration Mode Commands chapter).
If the GTPP group is not specified, then a default GTPP group in the accounting context will be used.
If this command is not specified, use the name of the accounting context configured in the SGSN service configuration mode (for 3G) or the GPRS service configuration mode (for 2G), either will automatically use a “default” GTPP group generated in that accounting context.
If the accounting context is specified in the GPRS service or SGSN service and in a call control profile, the priority is given to the accounting context of the call control profile.
Example
For this call control profile, the following command identifies an accounting context called acctng1 and associates a GTPP server group named roamers with defined charging gateway accounting functionality.
accounting context acctng1 gtpp group roamers
accounting mode
Configures the mode to be used for accounting – GTPP (default), RADIUS/Diameter or None.

Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
apn-restriction update-policy deactivate restriction
default apn-restriction
default
Creates a default APN restriction configuration.
update-policy deactivate restriction
Specifies one of the two restriction types to define the appropriate action if the APN restriction value received conflicts with the stored value:
•
least-restrictive: least restrictive value applicable when there are no already active PDP context(s).
•
most-restrictive: most restrictive is the most stringent restriction required by any already active PDP context(s).
Usage
When this feature is enabled, the SGSN will send the maximum APN restriction value in every CPC Request message sent to the GGSN. The SGSN expects to receive an APN restriction value in each PDP Context received from the GGSN. The SGSN stores and compares received APN restriction values to check for conflicts. In the case of a conflict, the SGSN rejects the PDP Context with appropriate messages and error codes to the MS.
If an APN restriction value is not assigned by the GGSN, the SGSN assumes the value of “1” (least restrictive) to allow APN restriction rules will be possible when valid values are assigned for new PDP Context(s) from the same MS.
Example
The following command applies the lowest level of APN restrictions:
apn-restriction update-policy deactivate least-restrictive
associate

remove associate { ho-restrict-list | hss-peer-service [ s13-interface | s6a-interface ] | tai-mgmt-db }
remove
Remove the specified association definition from the call control profile.
ho-restrict-list list_name
Identifies the handover restriction list that should be associated with this call control profile. list_name is an alphanumeric string of 1 through 64 characters.
hss-peer-service service_name
Associates a Home Subscriber Server (HSS) peer service with this call control profile. service_name is an existing HSS peer service expressed as an alphanumeric string of 1 through 63 characters.
[ s13-interface | s6a-interface ]
Optionally, identify the interface to be associated with the HSS service in this call control profile.
tai-mgmt-db tai-db_name
Identifies the tracking area identifier (TAI) database that should be associated with this call control profile. tai-db_name is an alphanumeric string of 1 through 64 characters.
This configuration overrides the S-GW selection and TAI list assignment functionality for a call that uses an operator policy associated with this call control profile. The TAI management object provides a TAI list for calls and provides S-GW selection functionality if a DNS is not configured for S-GW discovery for this operator policy or if a DNS discovery fails.
Usage
Use this command to associate handover restriction lists, HSS service (and interfaces), and TAI dB with the call control profile. This ensures that the information is available for application when a Request is received.
Repeat the command as needed to associate each feature.
Example
Link HO restriction list named HOrestrict1 with this call control profile:
associate ho-restrict-list HOrestrict1

user-device-release { before-r99 | r99-or-later } failure-code code
Default: disabled
Enables the SGSN to reject an Attach procedure based on the detected 3GPP release version of the MS equipment and selectively send a failure cause code in the reject message. The SGSN uses the following procedure to implement this configuration:
1.
When Attach Request is received, the SGSN checks the subscriber’s IMSI and current location information.
2.
Based on the IMSI, an operator policy and call control profile are found that relate to this Attach Request.
3.
Profile is checked for access limitations.
4.
Attach Request is checked to see if the revision indicator bit is set
•
if not, then the configured common failure code for reject is sent;
•
if set, then the 3GPP release level is verified and action is taken based on the configuration of this parameter
One of the following options must be selected and completed:
•
before-r99: Indicates the MS would be a 3GPP release prior to R99 and an appropriate failure code should be defined.
failure-code code: Enter an integer from 2 to 111.
•
r99-or-later : Indicates the MS would be a 3GPP Release 99 or later and an appropriate failure code should be defined.
failure-code code: Enter an integer from 2 to 111.
imei-query-type { imei | imei-sv | none }
This keyword set is specific to the MME.
Defines device Attach limitations if an IMEI is not already present in the Attach Request.
•
imei: Specifies that the MME is required to query the UE for its International Mobile Equipment Identity (IMEI).
•
imei-sv: Specifies that the MME is required to query the UE for its International Mobile Equipment Identity - Software Version (IMEI-SV).
•
none: Specifies that the MME does not need to query for IMEI or IMEI-SV.
verify-equipment-identity [ allow-on-eca-timeout | deny-greylisted | deny-unknown | verify-emergency ]
Specifies that the identification (IMEI or IMEI-SV) of the UE is to be performed by the Equipment Identity Register (EIR) over the S13 interface.
•
allow-on-eca-timeout: Configures the MME to allow equipment that has timed-out on ECA during the attach procedure.
•
deny-greylisted: Configures the MME to deny grey-listed equipment during the attach procedure.
•
deny-unknown: Configures the MME to deny unknown equipment during the attach procedure.
•
verify-emergency: Configures the MME to ignore the IMEI validation of the equipment during the attach procedure in emergency cases. This keyword is only supported in release 12.2 and higher.
Usage
Once the IMSI of an incoming call is known and matched with a specific operator policy, according to the filter definition of the mcc command, then the associated call control profile is selected to determine how the incoming call is handled.
By default, all attaches are allowed. If no access limitations are needed, then do not use the attach command.
note_smallImportant: Before using this command, ensure that the appropriate LAC information has been defined with the location-area-list command.
Use this command to define attach limitations for the call control profile.
Use this command to fine-tune the attach configuration specifying which calls/subscribers can attach and which calls are restricted from attaching and what failure code is included in the Reject message.
Attachment restrictions can be based on any one or combination of the options, such as location area code or access type. It is even possible to restrict all attaches.
The command can be repeated using different keyword values to further fine-tune the attachment configuration.
Example
For calls under the purview of this call control profile, the following command restricts the attaches of all subscribers using the GPRS access type.
attach restrict access-type gprs all
Use the next command to reverse the previous attach restrict command:
attach allow access-type gprs all
Or, change the attach restriction to only restrict attaches of GPRS subscribers from specified LACs included in location area list #2 and include failure-code 45 as the reject cause. This configuration requires two CLI commands:
attach restrict access-type gprs location-area-list instance 2
attach access-type gprs location-area-list instance 2 failure-code 45
In the case of a dual-access SGSN, it is possible to also add a second definition to restrict attaches of UMTS subscribers within the LACs included in location area list #3.
attach restrict access-type UMTS location-area-list instance 3
Change the configuration to allow attaches for GPRS access for all previously restricted LACs - note that GPRS attaches would still be limited:
no attach restrict access-type gprs all
Restrict (deny) all GPRS attach requests (coming from any location area) and assign a single failure code for the reject messages. This is a two command process:
attach restrict access-type gprs all
attach access-type grps all failure-code 22
Remove the restrictions defined above - so that the access type is reset to the default (both types) and the failure code returns to the default value (14).
default attach access-type gprs all failure-code

Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
authenticate on-first-vector
remove authenticate on-first-vector
remove
Removes the authenticate on-first-vector definition from the configuration file and resets the default behavior so that the SGSN waits to receive all vectors before beginning authentication towards the MS.
Usage
After an initial attach request, some end devices restart themselves after waiting for the PDP to be established. In such cases, the SGSN restarts and a large number of end devices repeat their attempts to attach. The attach requests flood the radio network, and if the devices timeout before the PDP is established then they continue to retry, thus even more traffic is generated.
To avoid the high traffic levels during PDP establishment, the SGSN has been modified to reduce the attach time, as much as possible, so that the devices can attach and discontinue sending requests. The current enhancement is intended to reduce the time needed to retrieve vectors over the GR interface by allowing the operator to configure the SGSN to start authentication towards the MS as soon as it receives the first vector from the AuC/HLR. With the new command included in the configuration, the SGSN begins the MS authentication process immediately after receiving the first vector from the HLR while the SAI continues in parallel.
Example
Use the following command to configure the SGSN to begin MS authentication immediately after receiving the first vector from the AuC/HLR:
authenticate on-first-vector
Use the following command to reset the default behavior, so that the SGSN waits to receive all vectors requested in the SAI from the AuC/HLR before begining authentication towards the MS:

Usage
Use this command to allow or restrict network-requested PDP context activation (NRPCA) based on access-type and location areas. NRPCA is used when there is downlink data at the GGSN for a subscriber, but there is no valid context for the already-established PDP address so the GGSN initiates an NRPCA procedure towards the SGSN.
This command can also be used to define the failure cause code that will be included in activation reject messages.
These commands can be repeated to define a unique set of NRPCA parameters for each access-type and each location area list.
The T3385-timeout and the max-actv-retransmission timers configure the retransmission timer and the number of retries for PDP context activation requests. Both of these timers are set in the SGSN service configuration mode.
The configuration for NRPCA can be viewed via the show call-control-profile full name profile_name. Statistics associated with NRPCA can be seen via the show gmm-sm statistics output and via the show sgtpc statistics verbose output.
Example
The following command changes the failure code for Reject messages from 200 (service not supported) to 205 (roaming restriction) for primary NRPCA for all GRPS access and all LACs:
network-initiated-pdp-activation primary access-type gprs all failure-code 205
The following command enables network-initiated primary PDP context activation for UMTS calls from the LACs in location-area-list 1:
network-initiated-pdp-activation allow primary access-type umts location-area-list instance 1
The following command restricts network-initiated primary PDP context activation for UMTS calls from the LACs in location-area-list 2:

rac rac_id
Identifies the foreign routing area code (RAC) of the peer-SGSN address to be configured in the static peer-SGSN address table. rac_id must be an integer from 1 to 255.
lac lac_id
Identifies the foreign location area code (LAC) ID of the peer-SGSN address to be configured in the static peer-SGSN address table. lac_id must be an integer from 1 to 65535.
nri nri
Identifies the network resource identifier stored in the P-TMSI (bit 17 to bit 23). nri must be an integer from 0 to 63.
note_smallImportant: Typically, use of this keyword is optional. However, it must be included in the command when Flex (SGSN-Pooling) is implemented.

address ip_address
•
ipv4 - specifies a valid address in IPv4 dotted-decimal notation.
•
ipv6 -
note_smallImportant: The ipv6 option is under development for future use and is not supported in this release.
Usage
Use this command to save time by avoiding DNS. This command enables a local mapping by setting the peer-SGSN IP address to be used for inter-SGSN Attach and inter-SGSN-RAU. When configured, if the SGSN receives a RAU or an Attach Request with a P-TMSI and an old-RAI that is not local, the SGSN consults this table and uses the configured IP address instead of resolving via DNS. If this table is not configured, then IP address resolution is done using DNS.
The MCC and MNC of the RAI are taken from the IMSI range configured in the operator policy and the LAC and RAC are configured here in the call control profile configuration mode.
The sgsn-address command differs from other Call Control Profile configuration mode commands in the following ways:
•
Within the SGSN’s call logic, all other configuration elements defined with the other commands in this mode are used after the IMSI is learnt. The configuration defined with this command is part of the decision logic prior to the IMSI being known.
•
With the peer-SGSN address configured using this sgsn-address command, the peer-SGSN-RAI’s MCC/MNC is used as a 5 or 6-digit IMSI and the operator policy and call control profile selection are completed.
note_smallImportant: Typically, use of this command is optional. However, it must be included in the configuration when Flex (SGSN-Pooling) is implemented if (1) the SGSN functions as a default SGSN, then configure the local-NRI of other SGSN with this command; or if (2) another SGSN is offloading, then configure the NB-RAI/null-NRI of the peer-SGSN with this command.
Example
Create a local peer-SGSN address mapping of an RAI with RAC of 123 and LAC of 4444 and an IPv4 address of 123.11.313.11 for the peer-SGSN:
sgsn-address rac 123 lac 4444 local address ipv4 123.11.313.11

E164_number
Specifies a string of 1 to 16 digits that serve as the SGSN’s E.164 identification.
Usage
This command configures the current SGSN E164 contact number.
The SGSN number configured for a call control profile is related to the SGSN number configured in the SGSN service configuration and/or in the GPRS service configuration. If the SGSN number is not configured as part of the call control profile configuration, then the SGSN number defined as part of the SGSN service or GPRS service configuration is used.
When the 3G SGSN supports multiple PLMNs configured through different IuPS services or when network sharing is implemented, then it may be required to use different SGSN numbers for each PLMN. In such cases, configure the per-PLMN SGSN number in a call control profile. SGSN number definition for a call control profile allows emulation of a different SGSN to each HLR per PLMN. SGSN number definitions in the call control profile also enable the SGSN to use a different SGSN number per operator when network sharing is implemented.

remove tau { imei-query-type | inter-rat security-ctxt }
remove
Deletes this TAU configuration from the call control profile.
imei-query-type { imei | imei-sv | none }
This keyword set is specific to the MME.
Sets the IMEI query-type if an IMEI (International Mobile Equipment Identity) is not already present.
•
imei: Specifies that the MME is required to query the UE for its International Mobile Equipment Identity (IMEI).
•
imei-sv: Specifies that the MME is required to query the UE for its International Mobile Equipment Identity - Software Version (IMEI-SV).
•
none: Specifies that the MME does not need to query for IMEI or IMEI-SV.
verify-equipment-identity [ allow-on-eca-timeout | deny-greylisted | deny-unknown | verify-emergency ]
Specifies that the identification (IMEI or IMEI-SV) of the UE is to be performed by the Equipment Identity Register (EIR) over the S13 interface.
•
allow-on-eca-timeout: Configures the MME to allow equipment that has timed-out on ECA during the attach procedure.
•
deny-greylisted: Configures the MME to deny grey-listed equipment during the attach procedure.
•
deny-unknown: Configures the MME to deny unknown equipment during the attach procedure.
•
verify-emergency: Configures the MME to ignore the IMEI validation of the equipment during the attach procedure in emergency cases. This keyword is only supported in release 12.2 and higher.
inter-rat security-ctxt { allow-mapped | native }
Configure inter-RAT parameters for TAU. This keyword provides the operator with the option of continuing with the mapped context or creating a new native context after an inter-RAT handover.
•
allow-mapped: Configures inter-RAT security-context type as mapped. Mapped security context is allowed after inter-RAT handover. This is the default value.
•
native: Configures inter-RAT security-context type as native only. Inter-RAT handover will always result in a native security context.
Usage
Use this command to define tracking area update procedures such as inter-RAT security context and IMEI query-type.
Example
The following command sets the IMEI query type to IMEI-SV:
tau imei-query-type imei-sv verify-equipment- identity

zone-code
Configures a zone code listing of one or more location area code (LACs) included in the zone.
Product
SGSN
Privilege
Security Administrator, Administrator
Syntax
zone-code zc_id location-area-code lac
no zone-code zc_id [ location-area-code lac ]
no
Removes either a specific LAC from the zone code list. If the location-area-code parameter is not included in the command, then the entire zone code list definition is removed from configuration.
zc_id
Identifies an instance of a zone code list as an integer from 1 to 65535.
An unlimited number of zone code lists can be configured per call control profile as the zone code lists are allocated dynamically. A maximum of 10 zone code lists can be configured per Call Control Profile.
location-area-code lac
Prompts for the location area-code(s), where the subscribers can roam, that are part of the zone. lac is an integer from 1 to 65535.
Repeat the command with this parameter to include up to 100 LACs in the zone code list.
Usage
note_smallImportant: While there is no limit to the number of zone codes that can be created, only 10 LACs per zone code can be defined.
Use this command to define zone code restrictions. Regional subscription data at the home location register (HLR) is used to determine the regional subscription area in which the subscriber is allowed to roam. The regional subscription data consists of a list of zone codes. A zone code is comprised of one or more location areas (identified by a LAC) into which the subscriber is allowed to roam. Regional subscription data, if present in the insert subscriber data (ISD) request from the HLR, defines the subscriber's subscription area for the addressed SGSN. It contains the complete list (up to 10 zone codes) that apply to a subscriber in the currently visited PLMN.
During the GPRS Location Update procedure, the zone code list is received in the ISD request from the HLR. The zone code list from the HLR is validated against the configured values in the operator policy. If matched, then the ISD is allowed to proceed. If not matched, then the ISD response is that the Network Node Area is Restricted and the GPRS Location Update procedure fails. If no zone codes are included in the ISD (whether or not the zone codes are defined in the SGSN configuration), then checking is not done.
Example
The following command defines multiple LACs for zone code 1:
zone-code 1 lac 413 212 113
