3.4 AT+CEER Extended Error Report
AT+CEER returns an extended error report regarding the reason of the last
•call release
• failure to set up a call (both mobile originated or terminated)
• failure to modify a call by using Supplementary Services
• failed attempt to activate, register, query, deactivate or deregister a Supplementary Service
• unsuccessful GPRS attach or unsuccessful PDP context activation
• GPRS detach or PDP context deactivation
The release cause report is presented in numeric format. Default output in case of a none-error-situation is
+CEER: 0,0,0. A description associated with each number can be found in the tables given in the following sub-
clauses and the relevant GSM specifications.
The first parameter
<locationID> serves to locate the other two parameters. Depending on the failure or
release cause either
<reason> or <ssRelease> are applicable, i.e. if <reason> ¹ 0, then <ssRelease> = 0.
Vice versa, if
<reason> = 0, then <ssRelease> may be ¹ 0.
AT+CEER is not available for data calls, please use ATS18=1 instead.
