Bias-Free Language

The documentation set for this product strives to use bias-free language. For the purposes of this documentation set, bias-free is defined as language that does not imply discrimination based on age, disability, gender, racial identity, ethnic identity, sexual orientation, socioeconomic status, and intersectionality. Exceptions may be present in the documentation due to language that is hardcoded in the user interfaces of the product software, language used based on RFP documentation, or language that is used by a referenced third-party product.

Chapter: BSSGP Cause Code Group Configuration Mode

BSSGP Cause Code Group Configuration Mode

Commands in this mode enable the operator to define multiple cause codes for the 2G service.

Mode

Exec > Global Configuration > LTE Policy Configuration > BSSGP Cause Code Configuration

configure > lte-policy > cause-code-group group_name protocol bssgp

Entering the above command sequence results in the following prompt: 

[local] host_name(bssgp-cause-code)

Important

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

end

Exits the current configuration mode and returns to the Exec mode.

SGSN

Privilege

Security Administrator, Administrator

Mode

Exec > Global Configuration > LTE Policy Configuration > BSSGP Cause Code Configuration

configure > lte-policy > cause-code-group group_name protocol bssgp

Entering the above command sequence results in the following prompt: 

[local]host_name(bssgp-cause-code)#

Syntax

radio-cause  cause_code  
no radio-cause  cause_code

no

When included with the command, the specified cause code is deleted from the group. If all cause codes are deleted from the group then the group is automatically deleted.

cause_code

Enter an integer from 0 to 255 to identify a BSSGP protocol radio cause code, as defined in the Radio Cause section of the 3GPP TS 48.028 specification.


Important

The SGSN does not support Enhanced Radio Status functionality; therefore, the SGSN treats cause code values 0x03 and 0x04 as "Radio contact lost with MS". Therefore, the valid configurable cause codes values are 0, 1, and 2.

Usage Guidelines

The command can be repeated to define up to 16 BSSGP cause codes. This means that that under each cause code group the maximum number of cause codes (ranap+bssgp+s1ap) that can be supported is 16.

Benefit of specifying the cause codes in a group :
  • if the BSSGP radio cause code configured by the operator matches with the radio cause received in the Radio Status message, and
  • if the Subscriber Overcharging Protection feature is enabled for 2G service in the GPRS-Service configuration,
  • then the S4-SGSN includes ARRL (Abnormal Release of Radio Link) bit in Release Access Bearer Request message Initiated on Ready-to-Standby state transition.

Example

Repeat the command with different cause values to create a group: 
radio-cause 1  
radio-cause 3
