Description
Set command enables or disables sending of unsolicited result codes, +CGEV: XXX from MT to TE in the case of
certain events occurring in the Packet Domain MT or the network. <mode> controls the processing of unsolicited result
codes specified within this command. <bfr> controls the effect on buffered codes when <mode> 1 or 2 is entered. If a
setting is not supported by the MT, ERROR or +CME ERROR: is returned.
Read command returns the current mode and buffer settings
Test command returns the modes and buffer settings supported by the MT as compound values.
Defined values
<mode>:
0
buffer unsolicited result codes in the MT; if MT result code buffer is full, the oldest ones can be discarded. No
codes are forwarded to the TE.
1 discard unsolicited result codes when MT-TE link is reserved (e.g. in on-line data mode); otherwise forward
them directly to the TE
2 buffer unsolicited result codes in the MT when MT-TE link is reserved (e.g. in on-line data mode) and flush
them to the TE when MT-TE link becomes available; otherwise forward them directly to the TE
<bfr>:
0
MT buffer of unsolicited result codes defined within this command is cleared when <mode> 1 or 2 is entered
1 MT buffer of unsolicited result codes defined within this command is flushed to the TE when <mode> 1 or 2 is
entered (OK response shall be given before flushing the codes)
Defined events
The following unsolicited result codes and the corresponding events are defined -
+CGEV: REJECT <PDP_type>, <PDP_addr>
A network request for PDP context activation occurred when the MT was unable to report it to the TE with a
+CRING unsolicited result code and was automatically rejected.
+CGEV: NW REACT <PDP_type>, <PDP_addr>, [<cid>]
The network has requested a context reactivation. The <cid> that was used to reactivate the context is provided
if known to the MT.
+CGEV: NW DEACT <PDP_type>, <PDP_addr>, [<cid>]
The network has forced a context deactivation. The <cid> that was used to activate the context is provided if
known to the MT.
+CGEV: ME DEACT <PDP_type>, <PDP_addr>, [<cid>]
The mobile termination has forced a context deactivation. The <cid> that was used to activate the context is
provided if known to the MT.
+CGEV: NW DETACH
The network has forced a PS detach. This implies that all active contexts have been deactivated. These are not
reported separately.
+CGEV: ME DETACH
The mobile termination has forced a PS detach. This implies that all active contexts have been deactivated. These
are not reported separately.
+CGEV: NW CLASS <class>
The network has forced a change of MT class. The highest available class is reported (see +CGCLASS).
