SMS and SS7 SMSC: Then vs Now
The first-ever SMS was sent in 1992 and it was “Merry Christmas.” Back then, only a few people used to have mobile phones, and texting was a new concept for them. But as mobile technology evolved, SMS shortly became the convenient method to connect better than post offices. On the technical side, SS7 (Signaling System 7) made it possible in real life. Created in the 1970s and 1980s, SS7 was meant to handle call setup and routing. Later on, it became the backbone for messaging that allowed text messages to travel discreetly and quickly across global networks.
Now apps like WhatsApp and Messenger took the spotlight, but SMS never disappeared. It is still crucial for bank alerts, verification codes, emergency alerts, and two-way communication in remote areas and places with poor internet access. The SS7 SMSC adapted along the way to handle messages in high volumes, integrated with new systems and became faster and less vulnerable.
What is SS7 SMSC?
The SS7 SMSC (signaling system 7 short message service center) is a key component of mobile telecommunications infrastructure. It’s the main server in a mobile network that processes SMS messages from their transmission, storage, and routing between users. SS7 is a global standard for telecommunication signaling that enables the streamlined exchange of data and messages across networks.
The SMSC acts as the intermediary that stores messages for a certain period when the receiver is unavailable at the moment so that messages are delivered as soon as the recipient is active. This is especially necessary in situations where the network is jammed or the user’s phone is switched off.
Key Constituents of SS7 SMSC
- Message Store: It is the part where SMS messages are stored temporarily until they are delivered.
- Routing Engine: This element helps to find the best route for the message to reach its receiver based on availability, network conditions, and other parameters.
- SMSC Interface: The interface links the SMSC with other aspects of the mobile network, such as mobile switching centers (MSCs) and home location registers (HLRs).
- Billing and Reporting System: It tracks the status and statistics of sent messages to help to create reports and manage costs for operators.
- Security Features: SS7 SMSC solutions have integrated encryption and authentication protocols to protect sensitive data from misuse.
How Does SS7 SMSC Work?
- Message Generation: A user sends an SMS message from their mobile phone.
- Message Routing: After that, the message is then sent to the SMSC, which serves as a middleman and stores it for some time if the receiver is not online.
- Recipient Availability Check: The SMSC then verifies the status of the recipient’s phone.
- Message Delivery: If the receiver’s device is active, the message is delivered. If not, it stays in the SMSC’s queue until delivery is done.
- Message Finalization: Once the message is successfully delivered, the SMSC approves the activity, and the message is wiped from its storage.
