What
is Fixed Line SMS ?
The Short Message Service (SMS) is available only
in Mobile services and Landline Services working on WLL principle. SMS
on wired landline is being introduced in the BSNL
The fixed line SMS feature allows a PSTN/ISDN subscriber to
send / receive messages (text or otherwise) to/from other PSTN/ISDN
subscribers or GSM mobile subscribers or E-mail users etc.
Fixed SMS - Current Scenario
Different Vendor Solutions exist or are being developed.
ETSI has standardised UBS (User Based Solution).
Work is on to develop an NBS (Network Based Solution) Standard as well.
ETSI’s idea of UBS gives a choice of 2 different protocols, both
of which rely on half duplex, bi-directional, 1200 baud FSK (Frequency
Shift Keying) based DLL protocols. Protocol-1 seems to be the preferred
choice for its full-compliance with ETSI GSM 3.40 SM-TL protocol
Capabilities of SM-TE(Telephone Instrument)
1.Support of SM-TL (ETSI GSM 3.40), and the Data Link and Physical layer
protocols mentioned.
2. Memory to store SM-SC numbers and SME sub addresses
3. Ringing Suppression
4. Memory Full
5. SM-TE Busy Scenario
CONCLUSION
FIXED SMS SERVICE WILL PREPARE THE INFRASTRUCTURE FOR FIXED MOBILE
CONVERGENCE AND E-GOVERNANCE IN ADDITION TO BRINGING LIFE BACK TO THE
LANDLINE SERVICES SCENARIO
Deployment Proposal
1.C-DOT would conduct a technology demonstration at its labs in Delhi
with one SBM acting as FSMS Gateway along with an SM-SC.
2. Initial deployment could be 3 FSMS Gateway SBMs, each connected to
the concerned SM-SC at the 3 pilot sites, viz., Kolkata, Patna and Coimbatore.
3. Post pilot deployment could consist of one SBM each in all prominent
cities connected to the nearest SM-SC (as on date 3 C-DOT SM-SCs at
the pilot sites and 4 of other vendors in the BSNL network).
4. Free and open routed level-1 on PSTN to the nearest FSMS Gateway
would be required.
5. FSMS Gateway node will generate the CDRs for billing and accounting
purposes.
