Table 10.1.57-1: +CSDBTSR parameter command syntax

Command	Possible response(s)
+CSDBTSR=[<n>]	+CME ERROR: <err>
+CSDBTSR?	+CSDBTSR: <n>
+CSDBTSR=?	+CSDBTSR: (list of supported <n>s)

Description

Set command controls the presentation of unsolicited result code +CSDBTSRI: <S-NSSAI>,<DNN>,<event_type>[,<S-NSSAI_DNN_backoff_time>,<5GSM_congestion_re-attempt_abo_indicator>,<5GSM_congestion_re-attempt_catbo_indicator>[,<procedure>]] reporting the S-NSSAI and DNN based back-off timer parameter values from MT to TE if the back-off timer is started, stopped, deactivated or expires. Refer clause 9.2 for possible <err> values.

Read command returns the current S-NSSAI and DNN based back-off timer unsolicited result code settings in the MT.

Test command returns values supported as a compound value.

Defined values

<n>: integer type.

0 Disable presentation of the unsolicited result code +CSDBTSRI.

1 Enable presentation of the unsolicited result code +CSDBTSRI.

<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]. 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]. This parameter shall not be subject to conventional character conversion as per +CSCS.

<event_type>: integer type. Indicates the event happened to the back-off timer.

0 The back-off timer is started.

1 The back-off timer is stopped.

2 The back-off timer is expired.

3 The back-off timer is deactivated.

<S-NSSAI_DNN_backoff_time>: integer type; indicates the remaining back-off time associated with the <S-NSSAI> and <DNN> 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.
