+CGREG: <n>,<stat>[,[<lac>],[<ci>],[<AcT>],[<rac>][,[<cause_type>],[<reject_cause>][,[<Active-Time>],[<Periodic-RAU>],[<GPRS-READY-timer>]]]]
+CGREG=? +CGREG: (list of supported <n>s)
Description
The set command controls the presentation of an unsolicited result code +CGREG: <stat> when <n>=1 and there is a change in the MT's GPRS network registration status in GERAN/UTRAN, or unsolicited result code +CGREG: <stat>[,[<lac>],[<ci>],[<AcT>],[<rac>]] when <n>=2 and there is a change of the network cell in GERAN/UTRAN. The parameters <AcT>, <lac>, <rac> and <ci> are provided only if available. The value <n>=3 further extends the unsolicited result code with [,<cause_type>,<reject_cause>], when available, when the value of <stat> changes. The value <n>=6 extends the unsolicited result code with [,<csg_stat>] when the value of <csg_stat> changes. The value <n>=7 extends the unsolicited result code with [,<csginfo>] when UE camps on a CSG cell. <csginfo> is displayed only when <csg_stat> is 1.
If the UE wants to apply PSM for reducing its power consumption, see +CPSMS command and TS 23.682, the set command controls the presentation of an unsolicited result code +CGREG: <stat>[,[<lac>],[<ci>],[<AcT>],[<rac>][,[<cause_type>],[<reject_cause>][,[<Active-Time>],[<Periodic-RAU>],[<GPRS-READY-timer>]]]]. When <n>=4 the unsolicited result code will provide the UE with additional information for the Active Time value, the extended periodic RAU value and the GPRS READY timer value if there is a change of the network cell in GERAN/UTRAN. The value <n>=5 further enhances the unsolicited result code with <cause_type> and <reject_cause> when the value of <stat> changes. The parameters <AcT>, <lac>, <rac>, <ci>, <cause_type>, <reject_cause>, <Active-Time>, <Periodic-RAU> and <GPRS-READY-timer> are provided only if available.
Refer clause 9.2 for possible <err> values.
The read command returns the status of result code presentation and an integer <stat> which shows whether the network has currently indicated the registration of the MT. Location information elements <lac>, <ci>, <AcT> and <rac>, if available, are returned only when <n>=2 and MT is registered in the network. The parameters [,<cause_type>,<reject_cause>], if available, are returned when <n>=3.
Test command returns values supported as a compound value. The parameter [,<csg_stat>], if available, is returned when <n>=6. The parameter [,<csginfo>], if available, is returned when <n>=7.

NOTE:
The syntax of the AT Set Command is corrected to make the parameter <cid> mandatory. Older versions of the specification had defined the parameter <cid> optional, however the UE behaviour was not defined.
Description
The set command allows the TE to specify the EPS Quality of Service parameters <cid>, <QCI>, [<DL_GBR> and <UL_GBR>] and [<DL_MBR> and <UL_MBR>] for a PDP context or Traffic Flows (see TS 24.301 and TS 23.203). When in UMTS/GPRS the MT applies a mapping function to UTMS/GPRS Quality of Service. Refer clause 9.2 for possible <err> values.
A special form of the set command, +CGEQOS= <cid> causes the values for context number <cid> to become undefined.
The read command returns the current settings for each defined QoS.
The test command returns the ranges of the supported parameters as compound values.
Defined values
<cid>
integer type; specifies a particular EPS Traffic Flows definition and a PDP Context definition (see the +CGDCONT and +CGDSCONT commands).

The QCI values 65, 66, 67, 69 and 70 are not allowed to be requested by the UE. If the TE requests a QCI parameter 65, 66, 67, 69 or 70, the MT responds with result code +CME ERROR: 181 (unsupported QCI value).

10.1.29  Delete non-active PDP contexts +CGDEL |R9|Word‑p. 300

Command Possible response(s)
+CGDEL[=<cid>][+CGDEL: <cid>[,<cid>[,...]]] +CME ERROR: <err>
+CGDEL=?
Description
The execution command +CGDEL=<cid> removes the indicated PDP context and removes all associated data related to the indicated PDP contexts that are not activated. The AT command will not delete or remove information for activated PDP contexts. The removed PDP context is listed by the +CGDEL: <cid> intermediate result code. If the initial PDP context is supported (see clause 10.1.0), +CGDEL=0 will return ERROR and the context will not be removed.
If <cid> points to a primary PDP context, the PDP context will be deleted together with all linked secondary PDP contexts if none of the PDP contexts are activated.
If <cid> points to a secondary PDP context, the PDP context will be deleted if it is not activated.
A special form of the command can be given as +CGDEL (with the =<cid> omitted). In this form, all primary PDP contexts that are not activated or have any activated secondary PDP contexts will be removed and all secondary PDP contexts that are not activated will be removed. The associated data of all the deleted PDP contexts will be removed, and the removed PDP context are listed by the +CGDEL: <cid>[,<cid>[,...]] intermediate result code. Activated PDP contexts will not cause this form of the command to return ERROR or +CME ERROR. Refer clause 9.2 for possible <err> values.
If the initial PDP context is supported (see clause 10.1.0), +CGDEL (with the =<cid> omitted) will not cause the initial PDP context to be removed or cause +CGDEL to return ERROR.
For an attempt to delete PDP context(s) which would violate these rules, a +CME ERROR response is returned. Refer clause 9.2 for possible <err> values.
Defined values
<cid>
integer type; specifies a particular PDP context definition (see the +CGDCONT and +CGDSCONT commands).
Implementation
Optional.
