10.3 AT^SISO
s
10.3 AT^SISO Internet Service Open
The AT^SISO write command starts the Internet session configured by the service profile. If the service opens
successfully, the URCs "^SISW" and "^SISR" will trigger the action to follow, either writing data with AT^SISW
or reading data with AT^SISR. If the "^SISW" and "^SISR" URCs notify that no data are available at all, or that
a data transfer has been successful, the service can be closed with AT^SISC. If an error occurs after opening or
while using a service then the URC type "^SIS" described below will be delivered.
In any case, an opened service must be finished by sending the Close command AT^SISC. This applies no matter
whether the service has been completed successfully (all data transmitted) or entered an error state (e.g. indicated
by the "^SIS" URC). It is also necessary when a service, such as POP3 or FTP, has already closed
automatically after successful data transfer and entered "2".
The AT^SISO read command requests the status of all Internet service profiles. One line is issued for every Internet
service profile. Information following the value "srvType" is issued only, if "srvType" was
given a valid value via AT^SISS. The read command can be used any time during operation or after closing a
service. In the latter case the response indicates the state of the last event related to a specific service profile. It
will be updated only when the same service profile is used again.

The URC may appear if an error occurs, for example after opening an Internet service with AT^SISO or any time
during operation. The URC also indicates a request for a mobile terminated Internet service client connection, or
a failure if a mobile terminated request is rejected. Furthermore, the URC may deliver an information element
resulting from a specific command given in the service profile.
The precise related to a varies greatly depending on the used service, the scenario
and the implementation of the remote server. A list of possible causes can be found in Section 10.7, Information
Elements Related to Internet Service URCs.
