SMS is the most popular data bearer
in GSM, which receives the highest percentage out
of both usage and total revenues. Apart from person-to-person
messaging, a rich variety of value added services
are offered via SMS.
Until now, services, which require a reply path
for subscribers (like televoting, etc.), have been
only offered to the operators’ own subscribers.
The main reason lying behind this is mainly the
technical limitation, which prohibits other network
subscribers to reply to the SMS from competitor
networks
These
kinds of SMS replies can be collected in two
different ways by third party applications:
|
|
|
|
Through
a client connection to SMSC :
Since such applications can be addressed
only by the SMSC of the home network
with 4 digit client numbers, subscribers
of other networks cannot send replies
over the SMSC of their network. |
 |
By
a GSM modem :
Although a global GSM number is available,
which enables other network subscribers
to send SMS to a specific operator’s
SMSC, GSM modems have quite low capacities
and also very low performance and therefore
they are practically unable to collect
bulk SMS. |
|
SM Collector overcomes these technical difficulties
and enables the operators to offer SMS based value
added services also to other GSM operators’
subscribers by providing a Global GSM number to collect
bulk number of SMS. SM Collector acts like a node
in the network and is connected to the core network
by SS7 links just like an SMSC.
|
|
|
SM Collector
provides a Global GSM number rather than a
four digit client number; for example like
“+90AAAXXXXXXX”. Therefore a subscriber
(of any foreign Network Operator) sends a
Short Message to this unique number, this
message follows the below procedures: |
|
|
|
The message is submitted to the SMSC of
his own network, |
|
|
It is delivered
to the home network of the SM Collector
(to the Gateway MSC of the home network
from the subscriber’s home GMSC),
|
|
In the home
network the message is delivered to the
SM Collector from the GMSC over SS7 links. |
|
SM Collector
delivers the message to a Value Added
Services Platform. |
