Unsolicited packet domain notifications are sent when the device is detached from the network or when a packet data connection is activated, deactivated, or modified.v1.0.xv1.1.xv1.2.xv1.3.x
For reference, see 3GPP 27.007 Ch. 10.1.19.
These notifications are subscribed using the +CGEREP command.
Syntax descriptions are as follows:
Network detach:
+CGEV: NW DETACH
Mobile Equipment (ME) detach:
+CGEV: ME DETACH
ME overheated and flight mode enabled:
+CGEV: ME OVERHEATED
Battery voltage is low:
+CGEV: ME BATTERY LOW
The ME has activated a default bearer:
+CGEV: ME PDN ACT <cid>[,<reason>]
The network has activated a dedicated bearer:
+CGEV: NW ACT <p_cid>,<cid>,<event_type>
The network has deactivated a default bearer:
+CGEV: NW PDN DEACT <cid>
The User Equipment (UE) has deactivated a default bearer:
+CGEV: ME PDN DEACT <cid>
The network has deactivated a dedicated bearer:
+CGEV: NW DEACT <p_cid>,<cid>,<event_type>
The UE has deactivated a dedicated bearer:
+CGEV: ME DEACT <p_cid>,<cid>,<event_type>
The network has modified a bearer:
+CGEV: NW MODIFY <cid>,<change_reason>,<event_type>
The UE has modified a bearer:
+CGEV: ME MODIFY <cid>,<change_reason>,<event_type>
IPv6 link is up for the default bearer:
+CGEV: IPV6 <cid>
IPv6 address resolution or refresh failure:
+CGEV: IPV6 FAIL <cid>
Requested procedure restricted:v1.1.xv1.2.x
+CGEV: RESTR <cause>,<validity>
Configuration of Access Point Name (APN) rate control:v1.3.x≥1
+CGEV: APNRATECTRL CFG <cid>,<number_of_packets>,<time_window>
Status of APN rate control:v1.3.x≥1
+CGEV: APNRATECTRL STAT <cid>,<status>[,<remaining_time>]
The following notification example shows that an initial Packet Data Network (PDN) connection is activated:
+CGEV: ME PDN ACT 0
The following notification example shows that the device is detached from network:
+CGEV: ME DETACH
The following notification example shows a restriction caused by throttling with temporary validity.
+CGEV: RESTR 2,2
