s

<numServices>(num)

Number of services using this Internet connection profile. 0...9

<conAddr>(str)

Local IP address of the Internet connection profile (empty if no address is associated yet).

Note

•Before opening a service profile based on a connection profile recently used, check with AT^SICI that the previous connection was properly closed. If AT^SICI confirms that the connection profile is in <conState> 0 (Down) the connection profile may be used again.

10.2.1Checking Connection Profile Status

at^sici?	Query the current status of the connection profile.
^SICI: 1,2,1,"10.10.0.161"	One connection profile has been created at <con-
	ProfileId>=1, and one service is opened using
	this connection profile. The Internet connection is in
	<conState>=2 ("Up").
OK

Assume the network connection is temporarily not available. (If URC presentation mode of network registration is enabled the state is shown by the URC "+CREG: 2").

at^sici?	Query once again the current status of the connec-
	tion profile.
^SICI: 1,3,1,"10.10.0.161"	Parameter <conState> has changed to state "Lim-
	ited up".
OK

The network connection is temporarily not available but the Internet connection is still established, so the host may decide to stop the data transfer to minimize the risk of losing data due to memory limitations.

at^sici?	Query once again the current status of the connec-
	tion profile.
^SICI: 1,2,1,"10.10.0.161"	After re-establishing the network connection, <con-
	State> reverts to state "Up".
OK
After closing the service with AT^SISC:
at^sici?	Query once again the current status of the connec-
	tion profile.
^SICI: 1,2,0,"10.10.0.161"	Parameter <numServices> has decreased. The
	bearer is still open because the service was closed
	before expiry of the inactivity timeout "inactTO" of
	AT^SICS.
OK	Query again the current status.
at^sici?
^SICI: 1,0,0,"0.0.0.0"	The inactivity timeout "inactTO" of AT^SICS has
	expired, therefore the bearer is closed now.
OK
