URC Remarks
+CGEV: ME MODIFY <cid>,<change_reason>,<event_
type>
The MT has forced a context modification.
+CGEV: ME DETACH The mobile station has forced a GPRS detach
+CGEV: ME CLASS <class> The mobile station has forced a change of MT class; the
highest available class is reported.
+CGEV: NW PDN ACT <cid>[,<reason>] The network has activated a primary context.
+CGEV: NW ACT <p_cid>,<cid>,<event_type> The network has forced a secondary context activation.
+CGEV: NW PDN DEACT <cid> The network has forced a primary context deactivation.
+CGEV: NW DEACT <p_cid>,<cid>,0 The network has forced a secondary context deactivation.
+CGEV: NW DEACT <p_cid>,<cid>,<event_type> The network has forced a secondary context deactivation.
+CGEV: NW DEACT <PDP_type>,<PDP_addr>,[<cid>] The network has forced a context deactivation.
+CGEV: NW MODIFY <cid>,<change_reason>,<event_
type>
The network has forced a context modification.
+CGEV: NW DETACH The network has forced a GPRS detach
+CGEV: NW CLASS <class> The network has forced a change of MT class (e.g. due to
service detach); the highest available class is reported.
+CGEV: VZW_SUBS_ACTION_NORMAL (0) - No
restriction to data traffic
No restriction to data traffic. The URC is provided only on
Verizon network.
+CGEV: REJECT <PDP_type>,<PDP_addr> The context activation is rejected.

13.11.1Description
Configures the GPRS network registration information. Depending on the <n> parameter value, a URC can be
issued:
+CGREG: <stat> if <n>=1 and there is a change in the GPRS network registration status in GERAN/UTRAN
+CGREG: <stat>[,<lac>,<ci>[,<AcT>,<rac>]] if <n>=2 and there is a change of the network cell in GERAN/
UTRAN
The parameters <lac>, <ci>, <AcT>, <rac> are provided only if available.
The read command provides the same information issued by the URC together with the current value of the
<n> parameter. The location information elements <lac>, <ci> and <AcT>, if available, are returned only when
<n>=2 and the MT is registered with the network.
When <n>=2, in UMTS RAT, unsolicited location information can be received if the network sends the
UTRAN INFORMATION MOBILITY message during dedicated connections; in the latter cases the reported
<ci> might be not correct because the UE in DCH state cannot read broadcast system information before
the change of serving cell. In contrast, in GSM RAT no unsolicited location information is received during
a CS connection.
If the GPRS MT also supports circuit mode services in GERAN/UTRAN and/or EPS services in E-UTRAN,
the +CREG / +CEREG commands return the registration status and location information for those
services.
