Cisco ASR 5000 Series Product Overview ▄
OL-22938-02
After verifying a subscription for the PLMN‘s SMS service, the SGSN connects with the SMSC (short message service
center), via a Gd interface, to relay received messages (from a mobile) using MAP-MO-FORWARD-REQUESTs for
store-and-forward.
In the reverse, the SGSN awaits messages from the SMSC via MAP-MT-FORWARD-REQUESTs and checks the
subscriber state before relaying them to the target MS/UE.
The SGSN will employ both the Page procedure and MNRG (mobile not reachable for GPRS) flags in an attempt to
deliver messages to subscribers that are absent.
The SGSN supports
charging for SMS messages, and
lawful intercept of SMS messages
.
For information on configuring and managing the SMS, refer to the SMS Service Configuration Mode chapter in the
Command Line Interface Reference.
