In term of SMS service, while delivering SMS from source mobile number to destination mobile number usually it is divided into Mobil Originated (MO) and Mobile Terminated (MT). Mobile Originated (MO) is a sending message process from source mobile phone to reach SMSC. While your mobile phone received “message sent”, it means that MO process is succeeded. Meanwhile Mobile Terminated is message sending process from SMSC to destination phone number

While MT message will be sent to destination number, there are some action will be did by telecommunication core network such as HLR and IN to make sure that the process is valid. IN (Intelligent network) will make sure whether the calling number has sufficient balance to make SMS service and HLR (Home Local Register) will make sure whether the source and destination phone numbers are valid numbers, registered and active.

Mobile Originated (MO) and Mobile Terminated (MT) process will succeed if authentication process on Intelligent Network (IN) and HLR is passed. Balance and registration status are the main authentication process

4. Home Local Register (HLR) or Visitor Local Register (VLR)
5. Short Message Service Centre (SMSC)
6. Intelligent Network (IN)

A message that sent by subscribers will be forward to the BTS, BSC and MSC and HLR/VLR. MSC will identify what kind of service is requested by subscriber, and it knew that it is a messaging service. The next step, MSC will forward the request to SMSC for next processing. SMSC will validate the phone number whether it is right to make a messaging service by checking the balance on Intelligent Network (IN). If it has sufficient balance, it will deducted and then deliver the message to the destination phone number.

Usually Telecommunication Company has more than one Short Message Service Centre (SMSC) to handle a huge SMS traffic. By this scenario, Telecommunication Company will share the total number of subscriber they have to each SMSC. It means that a SMS traffic will land to certainty SMSC and will be processed and delivered to the properly destination phone number.
