> CAMEL Service Configuration Mode Commands
> The CAMEL Service configuration mode provides a set of commands to define the parameters for the Customised Applications for Mobile networks Enhanced Logic (CAMEL) service functionality and the CAMEL interface - the Ge interface.
> CAMEL service enables operators of 2.5G/3G networks to provide operator-specific services (such as prepaid GPRS service and prepaid SMS service) to subscribers, even when the subscribers are roaming outside their home public land mobile network (HPLMN).
> When this mode is accessed, the command prompt should resemble:
> [context_name]asr5000(config-camel-service)#
> associate-sccp-network
> Configure an association between this CAMEL service and a specified SCCP network.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> associate-sccp-network sccp_network_id
> no associate-sccp-network
> no
> Removes the association with the CAMEL service configuration.
> sccp_network_id
> Identifies an already defined SCCP network.
> sccp_network_id : Enter an integer from 1 to 12.
> Usage
> The SCCP network must be configured prior to use this command.
> CAMEL service will not function unless an SCCP network is associated.
> Example
> Associate this CAMEL service with SCCP network configuration ID 2:
> associate-sccp-network 2
> end
> Exits the current configuration mode and returns to the Exec mode.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> end
> Usage
> Return to the Exec mode.
> exit
> Exits the current configuration mode and returns to the context configuration mode.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> exit
> Usage
> Move to the previous configuration mode.
> tcap destination-address
> Configure the gsmSCF address to be used to open TC dialogues.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> tcap destination-address { configured-address | received-address }
> default tcap destination-address
> configured-address
> Default.
> Instructs the SGSN to use the SCF address from the GPRS-CSI.
> received-address
> Instructs the SGSN to overwrite the gsmSCF address with the memorised gsmSCF address that was in the first response message to the InitialDPGPRS and then to use that gsmSCF address.
> Usage
> This command enables the operator to determine which gsmSCF address is to be used to open new TC dialogues. In accordance with 3GPP 29.078, section 14.1.4.1.3, this command enables the SGSN to establish new TC dialogues within the context of a current GPRS dialogue, based on the operators choice:

> • | to use a ‘received-address’ where the gprsSSF learns the gsmSCF address used in the first response message to the InitialDPGPRS and uses it to open new TC dialogues, or

> • | to use a ‘configured-address’ where the gprsSSF uses the gsmSCF address from the GPRS-CSI to open new TC dialogues.

> Example
> Configure the SGSN to overwrite the SCF address and to use the gsmSCF address received in the response message:
> tcap destination-address received-address
> timeout
> Configure a range of timers needed to support CAMEL service.
> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> timeout { gprs-apply-charging-report-ack-timer seconds | gprs-entity-release-ack-timer seconds | gprs-event-report-ack-timer seconds | gprs-tssf-timer seconds | sms-event-report-ack-timer seconds | sms-tssf-timer seconds | tc-guard-timer seconds }
> default timeout { gprs-apply-charging-report-ack-timer | gprs-entity-release-ack-timer | gprs-event-report-ack-timer | gprs-tssf-timer | sms-event-report-ack-timer | sms-tssf-timer | tc-guard-timer }
> default
> Resets the timers to default values.
> gprs-apply-charging-report-ack-timer seconds
> Configure the TCAP invoke timer to set the length of time the SGSN waits for an acknowledgement after sending an ApplyChargingReportGPRS to the SCF.
> seconds : Enter an integer from 1 to 20. Default: 4
> Important: This timer value should be less than the value configured for the tc-guard-timer.
> gprs-entity-release-ack-timer seconds
> Configure the TCAP invoke timer to set the length of time the SGSN waits for an acknowledgement from the SCF after sending Entity Release information.
> seconds : Enter an integer from 1 to 20. Default: 4
> gprs-event-report-ack-timer seconds
> Configure the TCAP invoke timer to set the length of time the SGSN waits for an acknowledgement from the SCF after the SGSN sends an event report.
> seconds : Enter an integer from 1 to 20. Default: 4
> gprs-tssf-timer seconds
> Configure the GPRS TSSF timer to set the length of time the SGSN waits for an instructions from the SCF. On expiry the SGSN handles the transaction through the default handling specified in the corresponding CSI.
> seconds : Enter an integer from 1 to 10. Default: 5
> sms-event-report-ack-timer seconds
> Configure the TCAP invoke timer to set the length of time the SGSN waits for an acknowledgement from the SCF after the SGSN sends an event report for SMS.
> seconds : Enter an integer from 1 to 20. Default: 4
> sms-tssf-timer seconds
> Configure the SMS TSSF timer to set the length of time the SGSN waits for an instructions from the SCF. On expiry the SGSN handles the transaction through the default handling specified in the corresponding CSI.
> seconds : Enter an integer from 1 to 10. Default: 5
> tc-guard-timer seconds
> Configure the guard tier to start when the SGSN sends ApplyChargingReportGPRS to the SCF. On expiry the SGSN closes the TCAP dialogue if the GPRS Dialogue state is “monitoring”. Default handling complies with 3GPP 23.078.
> seconds : Enter an integer from 1 to 10. Default: 5
> Important: This timer value should be greater than the value configured for the gprs-apply-charging-report-ack-timer.
> Usage
> The SCCP network must be configured prior to use this command.
> CAMEL service will not function unless an SCCP network is associated.
> Repeat the command to configure multiple timers.
> Example
> Set the tc-guard timer for 4:
> tc-guard-timer 4
