9. SYSTEM DESCRIPTION
Calls from Mobiles
See figure.
To make an outgoing call, you use a standard international telephone number
with the 00 prefix. The MES automatically includes information to identify itself
and the particular device that originates.
System signalling
The LES uses the identifying information of the attached device for billing
purposes.
The MES transmits the dialing information on a channel specially assigned by
the NCS to the LES.
LES routes the call over the public telecommunications networks to the intended
destination. When the called party responds, the call proceeds.
Call announcement from mobile to fixed:
The MES uses the Return Identity (RTNID) to communicate with the LES. It uses
the TermlD to identify its IMN number and the service in use.
The attached equipment dials the number and transmits its MSN number to the
MES. The MES routes the MSN to a TermlD.
LES checks that the RTNID is commissioned before connecting the call to the
fixed net.
