Table 10.1.41-1: +CABTSR parameter command syntax

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

Description

Set command controls the presentation of unsolicited result code +CABTSRI: <apn>,<event_type>[,<residual_backoff_time>,<NSLPI>[,<procedure>]] reporting the APN 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 APN 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 +CABTSRI.

1 Enable presentation of the unsolicited result code +CABTSRI.

<apn>: string type. A logical name that was used to select the GGSN or the external packet data network.

<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.

<residual_backoff_time>: integer type. Indicates the remaining back-off time associated with the <apn> in seconds. When the back-off timer is deactivated, the parameter <residual_backoff_time> is omitted.

<NSLPI>: integer type. Indicates the NAS signalling priority requested for this PDN connection.

0 Indicates that this PDN connection was activated with the value for NAS signalling low priority indicator set to "MS is configured for NAS signalling low priority".

1 Indicates that this PDN connection was activated with the value for NAS signalling low priority indicator set to "MS is not configured for NAS signalling low priority".

<procedure>: integer type. Indicates the procedure(s) for which the back-off timer applies. When <procedure>=0 the information returned is associated with timer T3396. For all other values of <procedure> the information returned is associated with the back-off timer as specified in 3GPP TS 24.008 [8], 3GPP TS 24.301 [83] or 3GPP TS 24.501 [161] for the various session management procedures or mobility management procedures. When the parameter <procedure> is omitted, the back-off timer is deactivated.

0 All procedures.

1 Standalone PDN connectivity procedure as specified in 3GPP TS 24.301 [83], clause 6.5.1.

2 Bearer resource allocation procedure as specified in 3GPP TS 24.301 [83], clause 6.5.3.

3 Bearer modification procedure as specified in 3GPP TS 24.301 [83], clause 6.5.4.

4 PDP context activation procedure as specified in 3GPP TS 24.008 [8], clause 6.1.3.1.

5 Secondary PDP context activation procedure as specified in 3GPP TS 24.008 [8], clause 6.1.3.2.

6 PDP context modification procedure as specified in 3GPP TS 24.008 [8], clause 6.1.3.3.

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

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

9 EPS attach procedure piggybacked with PDN connectivity procedure as specified in 3GPP TS 24.301 [83], clause 5.5.1.

NOTE: <procedure>=7 and <procedure>=8 apply to the DNN back-off timer as specified in N1 mode (see 3GPP TS 24.501 [161]).

Implementation

Optional.
