• call release<br />
• failure to set up a call (both mobile originated or terminated)<br />
• failure to modify a call by using Supplementary Services<br />
• failed attempt to activate, register, query, deactivate or deregister a Supplementary Service<br />
• unsuccessful GPRS attach or unsuccessful PDP context activation<br />
• GPRS detach or PDP context deactivation<br />
The release cause report is presented in numeric <strong>for</strong>mat. Default output in case of a none-errorsituation<br />
is +CEER: 0,0,0. A description associated with each number can be found in the tables<br />
given in the following subclauses and the relevant GSM specifications.<br />
The first parameter serves to locate the other two parameters. Depending on the<br />
failure or release cause either or are applicable; i.e., if ≠ 0,<br />
then = 0.<br />
Vice versa, if = 0, then may be ≠ 0.<br />

Parameter Description:<br />
<br />
Location ID as number code. Location IDs are listed in Section 3.4.1, Cause Location ID <strong>for</strong> the extended error<br />
report. Each ID is related with another table that contains a list of s or s.<br />
<br />
Reason <strong>for</strong> last call release as number code. The number codes are listed in several tables, sorted by different<br />
categories in the following subclauses. The tables can be found proceeding from the Location ID given in<br />
Section 3.4.1, Cause Location ID <strong>for</strong> the extended error report.<br />
<br />
Release cause <strong>for</strong> last Supplementary Service call (listed in Section 3.4.5, GSM Release cause <strong>for</strong><br />
Supplementary Service Call) or last call related use of a Supplementary Service (listed in Section 3.4.10,<br />
Release cause <strong>for</strong> Call-related Supplementary Services (CRSS)).<br />
Examples:<br />

<strong>AT</strong>D”01751223344”;<br />
A mobile originated call is rejected by the remote party.<br />
NO CARRIER<br />
Call setup is terminated with NO CARRIER.<br />
<strong>AT</strong>+CEER<br />
To check the cause, the caller enters <strong>AT</strong>+CEER.<br />
+CEER: 8,21,0 The Location ID 8 in Section 3.4.1 points to Section 3.4.4, where 21 =<br />
OK<br />
“Call rejected”. 0 = “No error” refers to parameter that is not applicable.<br />
Example 2<br />
The user attempts to set up a multiparty call, though there are only two parties involved in the present<br />
conversation:<br />
<strong>AT</strong>D”01751223344”;<br />
OK<br />
<strong>AT</strong>+CHLD=2<br />
OK<br />
<strong>AT</strong>+CHLD=3<br />
+CME ERROR:<br />
<strong>AT</strong>+CEER<br />
+CEER: 22,0,2 The<br />
operation temporary not allowed<br />
Location ID 22 in Section 3.4.1 points to release cause <strong>for</strong> Call-Related Supplementary<br />
Services (CRSS), where 2 = “Initial conditions not fulfilled (one active, one held call)”. 0 =<br />
“No error” refers to parameter that is not applicable.<br />
Example 3<br />
The user attempts to activate call barring. Activation is denied by the network since the password is blocked after<br />
previous failures to enter the password.<br />
<strong>AT</strong>+clck=oi,1,”0000”,3;<br />
+CME ERROR:<br />
incorrect password<br />
<strong>AT</strong>+CEER<br />
+CEER: 35,0,43 The Location ID 35 in Section 3.4.1 points to Section 3.4.5, where 43 =<br />
OK<br />
“NumberOfPWAttemptsViolation” may mean that a wrong password has been entered <strong>for</strong><br />
