Parameter Type Description
<mode> Number Controls the processing of URCs specified within this command. Allowed values:
• 0 (default value): buffer URCs in the MT; if the buffer is full the oldest ones will be
discarded
• 1: discard URCs when V.24 link is reserved (online); otherwise forward them directly
to the DTE
• 2: buffer URCs in the MT when link reserved (online) and flush them to the DTE when
the link becomes available; otherwise forward them directly to the DTE
<bfr> Number Controls the effect on buffered codes when <mode> 1 or 2 is entered. Allowed values:
• 0 (default value): MT buffer of URCs defined within this command is cleared when
<mode> 1 or 2 is entered
• 1: MT buffer of URCs defined within this command is flushed to the DTE when
<mode> 1 or 2 is entered (OK is given before flushing the codes)
<cid> Number See <cid>
<reason> Number Indicates whether the reason why the context activation request for PDP type IPv4v6
was not granted:
• 0: IPv4 only allowed
• 1: IPv6 only allowed
• 2: single address bearers only allowed
• 3: single address bearers only allowed and MT initiated context activation for a
second address type bearer was not successful
<cid_other> Number Indicates whether the context identifier allocated by MT for an MT initiated context
of a second address type
<p_cid> Number Numeric parameter that identifies the particular PDP context definition, specified
using +CGDCONT, to which a secondary PDP context definition will be associated
using +CGDSCONT.
This parameter is only locally valid on the interface TE-MT.
<event_type> Number Indicates whether the event is informational or whether the TE has to acknowledge it:
• 0: informational event
• 1: information request: acknowledgement required
<change_reason> Number Indicates what kind of change occurred:
• 1: TFT only changed
• 2: QoS only changed
• 3: both TFT and QoS changed
<PDP_type> Number See <PDP_type>
<PDP_addr> Number See <PDP_addr>
<class> String GPRS mobile class. Allowed values:
• "A": class A mode of operation (A/Gb mode), or CS/PS mode of operation (Iu mode)
(highest mode of operation)
• "B": class B (circuit-switched and packet-switched data alternatively supported)
• "CG": class C (one service only) in GPRS mode
• "CC": class C (one service only) in circuit-switched (GSM) mode

URC Remarks
+CGEV: ME PDN ACT <cid>[,<reason>[,<cid_other>]] The MT has activated a primary context.
+CGEV: ME ACT <p_cid>,<cid>,<event_type> The network has responded to a MT initiated secondary
context activation.
+CGEV: ME PDN DEACT <cid> The MT has forced a primary context deactivation.
+CGEV: ME DEACT <PDP_type>,<PDP_addr>,[<cid>] The MT has forced a context deactivation.
+CGEV: ME DEACT,<p_cid>,<cid>,0 The UE has forced a secondary context deactivation.
+CGEV: ME DEACT <p_cid>,<cid>,<event_type> The MT has forced a secondary context deactivation.
