Service type Graceful Immediate
Socket
FTP
TCP/IP connection will be closed after the
transmission of remaining data has completed.
FTP upload:
The "OK" response following the command
AT^SISC=, indicates that the FTP service has
accepted the close command - it DOES NOT
indicate the successful completion of the FTP
service close procedure. Successful completion
will be indicated by the appropriate URC
"^SISW: x,2". The host application can force a
service shutdown (= 1) if the
aforementioned URC doesn't occur after a
user defined timeout.
TCP/IP connection is closed immediately. All
remaining data are lost.
FTP download:
Same as immediate: TCP/IP
connection is closed immediately.
HTTP TCP/IP connection is closed immediately. TCP/IP connection is closed immediately.
SMTP
POP3
The SMTP service sends some "closing"
commands which are necessary to mark the
email as successfully sent on the server. The
service enters the "Closing"
and remains in this state until the final protocol
exchange with the SMTP server has completed.
The "OK" response following the command
AT^SISC=, indicates that the SMTP service has
accepted the close command - it DOES NOT
indicate the successful completion of the
SMTP service close procedure. Successful
completion will be indicated by the appropriate
URC "^SISW: x,2". The host application
can force a service shutdown (= 1) if the aforementioned URC doesn't
occur after a user defined timeout.
Same as immediate: TCP/IP
connection is closed immediately.
TCP/IP connection is closed immediately. All
remaining data are lost.
The SMTP service closes the TCP/IP connection
immediately. Email transfer is aborted.
This mode can be used to cancel an SMTP
operation.
TCP/IP connection is closed immediately.
Once the last service has been closed the bearer shuts down after a timeout of 20 seconds (i.e. the connection
profile GPRS0 or CSD is closed). If a service related to the same connection profile starts up again whithin this
time frame, the bearer will not be closed, but started again. This speeds up the handling of several service
requests. Within this time frame it is neither possible to change the bearer type (from GPRS to CSD or vice versa)
nor to start a service based on a different connection profile.
To disconnect the bearer before the timeout expires the command AT+CGATT=0 can be used in the case of
GPRS and ATH in the case of CSD.
