The SMSc is very similar in appearance to the RMSc. However, it has some significant differences. First of all, the SMSc uses a polymer body instead of an aluminum one. I prefer a tough aluminum housing for an optic as it might get banged around a bit. Nevertheless, polymer can be very tough and is likely acceptable in this application. SMSC was established in 1978 as a full member of the Mississippi Soccer Association (MSA) which was formed in 1974 with the United States Youth Soccer Association. In 1982, SMSC started the original Select Soccer Program in our area. The founding fathers of this program were volunteers.
Every node in the SS7 network needs an addresses or global title (GT), to reach the rest of the nodes in the network. Smsc or message service center number is the Global title of SMSC. SMSC is an SS7 node for messaging, located in HPLMN of a mobile network operator.

When there is a mobile-originated SMS, in MO-ForwardSM of GMS map protocol, SCCP called party address is the SMSC number and in Mobile terminated SMS, SCCP calling party address is the SMSC number.
How phone uses SMSC number?
SMS uses the SS7 protocol for messaging. Each node in the ss7 network is identified by a global title. When a user sends the SMS, it first reaches the VLR in the roaming network. VLR get SMSC number or GT from SMS. Based on GT, VLR sends MO-SMS to the service center.
An SMS may be in multiple parts, SMSC does the assembly of message segments. Each segment has an SMSC number called party. The SMS from VLR to SMSC uses the SS7 protocol.
Use of number in SMSC:
While sending MT-SMS, SMSC set in calling party its own SMSC number or GT. So that the responses can be routed back, from the destination network. Two GSM MAP operations (SRI-SM and Forward-SM) over ss7/ Sigtran are used by SMSC for MT-SMS.
How to change the SMSC number?
Once a sim card is inserted into the mobile device, the service center address automatically set or its update by the mobile network operator over the air. But still, there are situations when outgoing SMS is not working.
This may be because the SMSC number stored in the phone is not correct or mobile subscriber is not allowed for messaging service.
In both cases, the mobile subscriber needs to call customer care. If SMS is not working because of, no subscription for messaging service on HLR. The customer care executive can update the subscription profile on HLR for SMS service.

Basic trajectories[edit]
SMS can be directed in several ways:
- From mobile to another mobile - referred to as MO-MT (Mobile Originated - Mobile Terminated)
- From mobile to a content provider (also known as Large Account / ESME) - referred to as MO-AT (Mobile Originated - Application Terminated)
- From application to a mobile - referred to as AO-MT (Application Originated - Mobile Terminated)
Operation[edit]
The tasks of an SMSC can be described as
- Reception of text messages (SMS) from wireless network users
- Storage of text messages
- Forwarding of text messages
- Delivery of text messages (SMS) to wireless network users
- Maintenance of unique time stamps in text messages
When a user sends a text message (SMS message) to another user, the message gets stored in the SMSC (short message service centre), which delivers it to the destination user when they are available. This is a store and forward option.
An SMS centre (SMSC) is responsible for handling the SMS operations of a wireless network.
- When an SMS message is sent from a mobile phone, it will first reach an SMS centre.
- The SMS centre then forwards the SMS message towards the destination.
- The main duty of an SMSC is to route SMS messages and regulate the process. If the recipient is unavailable (for example, when the mobile phone is switched off), the SMSC will store the SMS message.
- It will forward the SMS message when the recipient is available and the message's expiry period is not exceeded.

SMSCs can be used to interface with other applications, for example a spreadsheet can interface with the SMSC allowing messages to be sent SMS from an Excel spreadsheet, or to send an SMS from Excel. Inbound messages to a long number or short code can also be passed through the SMSC allowing m2m communications or Telematics.
Validity period of an SMS message[edit]
An SMS message is stored temporarily in the SMS center if the recipient mobile phone is unavailable. It is possible on most mobile handsets to specify an expiry period after which the SMS message will be deleted from the SMS center. Once deleted, the SMS message will no longer be available for dispatch to the recipient mobile phone (even if it comes on line). The validity period should be regarded by the handset user as a request, as the SMSC itself can be configured to ignore or otherwise handle message delivery schedules.
Message status reports[edit]
The SMS sender needs to set a flag in the SMS message to notify the SMS centre that they want the status report about the delivery of this SMS message. This is usually done by changing a Setting on the mobile handset.
