> SGSN Service Configuration Mode Commands
> The SGSN Service configuration mode is used within the global configuration mode to specify the 3G operations of the SGSN and the available SGSN services for a specific context.
> SGSN Service works with MAP Service, SGTP Service, GTPP Group, and IuPS Service. All five of these services must be configured to enable a 3G SGSN to communicate with other elements within a UMTS network.
> In this mode, the command prompt should appear like:
> [<ctx_name>]hostname(config-sgsn-service)#
> Important: The commands or keywords/variables that are available are dependent on platform type, product version, and installed license(s).
> accounting
> This command defines the accounting context name and enables/disables specific types of CDR generation for the accounting in the SGSN service.

> Syntax
> accounting ( cdr-types { mcdr | scdr | sms { mo-cdr | mt-cdr } } + | context cntx_name }
> default accounting cdr-types
> no accounting ( cdr-types | context }
> default
> Returns the system to default settings for the selected type of CDR.
> no
> Removes the pre-configured type of CDR generation for accounting from the SGSN service.
> cdr-types { mcdr | scdr | sms { mo-cdr | mt-cdr } +
> Default: enabled
> Defines the types of CDRs to be generate:d within the specified SGSN service for accounting:

> • | mcdr Enables generation of M-CDRs.

> • | scdr : Enables generation of S-CDRs.

> • | sms : Enables generation of SMS-type CDRs based on one of the following:

> • | mo-cd: : SMS CDRs orignates from the mobile.

> • | mt-cdr: SMS CDRs terminates at the mobile.

> +
> Specifies that the specified keywords with in the group can be entered multiple times with a single command.
> context cntx_name
> Specifies an accounting context to be associated with the SGSN service.
> cntx_name: Define a string of 1 to 79 alphanumeric characters.
> Usage
> Use this command to define the type of CDRs to generate for SGSN service. By default all type of CDRs are generated. Note that change of this configuration will be applied to new call and/or to new PDP contexts only.
> By default, generation of the S-CDR, M-CDR, SMS-MT-CDR, and SMS MO-CDR types is enabled.
> Example
> The following command configures the system to generate CDRs of M-CDR type for accounting in the current SGSN service:
> accounting cdr-types mcdr
> admin-disconnect-behavior

> Product
> SGSN
> Privilege
> Security Administrator, Administrator
> Syntax
> admin-disconnect-behavior { clear-subscription | detach-type { reattach-not-required | reattach-required } }
> [ default | no ] admin-disconnect-behavior { clear-subscription | detach-type }
> clear-subscription
> Including this keyword in the configuration instructs the SGSN to clear subscriber contexts and the subscription data database whenever the clear subscribers all command is issued (from the Exec mode) for attached subscribers. As well, the SGSN will issue an appropriate Map-Purge-MS-Req to the HLR if needed.
> Default: disabled
> detach-type
> Including this keyword defines which type of detach instruction to include in the Detach-Request message during an Admin-Disconnect procedure. One of the following options must be included when this command is entered:

> • | reattach-not-required

> • | reattach-required

> Default: reattach-required
> default | no
> Including either default or no keyword in the command, instructs the SGSN to use the default value for the specified parameter.
> Usage
> Include the clear-subscription keyword with this command configuration to ensure that more than attached MM-context and active PDP-contexts are cleared when the clear subscribers all command is issued for attached subscribers.
> To clear subscription data for detached subscribers, refer to the sgsn clear-detached-subscriptions command described in the Exec mode chapter.
> Including the detach-type keyword with this command instructs the SGSN to include either a ‘reattach-required’ or a ‘reattach-no-required’ instruction in the Detach-Request message.
> Example
> Configure the SGSN to clear data such as PTMSI allocated, auth-vectors received, and NGAF flag values stored in the subscriber database for attached subscribers:

> time : Enter any integer from 60 to 40000000.
> tariff time1 mins hours [ time2 mins hours time3 mins hours time4 mins hours ]
> Specifies the time-of-day (based on a 24-hour clock) to close the current statistics container in the CDR, but not necessarily the CDR itself. One tariff time must be defined and up to four tariff times can be specified.
> Important: The system assumes that the billing system uses the day/date to determine if the statistics container represents an actual tariff period.

> • | mins: The minutes of the hour. Enter an integer from 0 to 59.

> • | hours: The hour of the day. Enter an integer from 0 to 23.

> volume { downlink down_vol uplink up_vol | total total_vol }

> total_vol : Enter any integer from 100000 to 400000000.
> Usage
> Charging characteristics consist of a profile index and behavior settings. This command configures the profile index for the SGSN’s charging characteristics. The SGSN supports up to 16 profile indexes.
> Example
> The following command configures a profile index of 10 with tariff times of 7:00 AM and 7:30 PM:

> Syntax
> check-imei-timeout-action [ continue | reject ]

> default
> Rejects the Attach or ISRAU procedure if a Check-IMEI timeout occurs.
> continue
> Instructs the SGSN to continue the Attach or ISRAU procedure if a Check-IMEI timeout occurs because the EIR is not reachable. This functionality matches standard call flow.
> reject
> Instructs the SGSN to reject the Attach or ISRAU procedure if a Check-IMEI timeout occurs.
> Usage
> Use this command only if the Gf interface (EIR) is available in the network. This command controls the SGSN reaction if the Check-IMEI procedure fails due to a timeout.
> The continue option allows the SGSN to go forward with the MS Attach or RAU, if the first Check-IMEI fails to reach the EIR due to a timeout. Any subsequent activity (such as a RAU or Service Request would force another Check-IMEI towards the EIR. If this subsequent MAP Check-IMEI should fail, then the same policy of continuing the procedure would apply.

> Multiple NRI values can be identified by providing multiple nri-values separated by a blank space for example: nri length 6 nri-value 29 43 61
> Usage
> Use this command to identify the SGSN identified with the NRI in the MS generated P-TMSI.
> This command adds or removes the Iu Flex configuration for this SGSN service. When using Iu Flex, all keywords must be defined. The command can be repeated to specify different values for any of the keyword parameters. If more than one NRI is configured, the SGSN service will round-robin between the available NRIs when new subscribers (re)connect.
> Use this command to retrieve the NRI (identity of an SGSN) stored in in bits 23 to 18 of the packet-temporary mobile subscriber identity (P-TMSI). If more than one NRI value is configured, the SGSN service will round-robin between the available NRIs when new subscribers (re)connect.
> When using MOCN mode for network sharing without SGSN pooling, the NRI length and the NRI value should both be used.
