Description

The execution command returns the relevant information in the MT for the S-NSSAI and DNN based back-off timer parameter value <S-NSSAI_DNN_backoff_time>, <5GSM_congestion_re-attempt_abo_indicator>, <5GSM_congestion_re-attempt_catbo_indicator> and <procedure> for the <S-NSSAI> and <DNN> combination if the back-off timer is running.

If the parameter <S-NSSAI> in the execution command is omitted, the DNN specific information for all S-NSSAIs associated with running back-off timers are returned.

If the parameter <DNN> in the execution command is omitted, the S-NSSAI specific information for all DNNs associated with running back-off timers are returned.

If both the parameters <S-NSSAI> and <DNN> are omitted, the relevant information for all S-NSSAI and DNN combinations associated with running back-off timers are returned.

Defined values

<S-NSSAI>: string type in hexadecimal format. Dependent of the form, the string can be separated by dot(s) and semicolon(s). The S-NSSAI is associated with the back-off timer for identifying a network slice in 5GS, see 3GPP TS 23.501 [165] and 3GPP TS 24.501 [161]. When <S-NSSAI> indicates an empty string (""), the parameter <S-NSSAI_DNN_backoff_time> in the response is associated with no S-NSSAI as specified in 3GPP TS 24.501 [161]. Refer parameter <S-NSSAI> in clause 10.1.1. This parameter shall not be subject to conventional character conversion as per +CSCS.

<DNN>: string type; indicates the DNN associated with the back-off timer for identifying a data network in 5GS, see 3GPP TS 23.501 [165] and 3GPP TS 24.501 [161]. When <DNN> indicates an empty string (""), the parameter <S-NSSAI_DNN_backoff_time> in the response is associated with no DNN as specified in 3GPP TS 24.501 [161]. This parameter shall not be subject to conventional character conversion as per +CSCS.

<S-NSSAI_DNN_backoff_time>: integer type; indicates the remaining back-off time associated with the <S-NSSAI> and <DNN> combination in seconds. When the back-off timer is deactivated, the parameter <S-NSSAI_DNN_backoff_time> is omitted.

<5GSM_congestion_re-attempt_abo_indicator>: integer type. Indicates whether the back-off timer is applied in the registered PLMN or all PLMNs.

0 The back-off timer is applied in the registered PLMN.

1 The back-off timer is applied in all PLMNs.

<5GSM_congestion_re-attempt_catbo_indicator>: integer type. Indicates whether the back-off timer is applied in the current access type or both 3GPP access type and non-3GPP access type.

0 The back-off timer is applied in both 3GPP access type and non-3GPP access type.

1 The back-off timer is applied in the current access type.

<procedure>: integer type. Indicates the procedure(s) for which the back-off timer applies. When <procedure>=0 the information returned is associated with timer T3584. For all other values of <procedure> the information returned is associated with the back-off timer as specified in 3GPP TS 24.501 [161] for the various session management procedures. When the parameter <procedure> is omitted, the back-off timer is deactivated.

0 All procedures.

1 PDU session establishment procedure (see 3GPP TS 24.501 [161], clause 6.4.1)

2 PDU session modification procedure (see 3GPP TS 24.501 [161], clause 6.4.2).

Implementation

Optional.
