A Short Message Service Center (SMSC) typically handles the SMS-related operations of a wireless network.
When an SMS is sent, it will be sent to the SMS center first and then to the intended recipient. In a nutshell, the main function of an SMSC is to route SMSs and regulate the overall process. In cases where the recipient is unavailable, the SMSC will store the SMS, to be forwarded when the recipient becomes available.
Typically, the SMSC supports basic SMS applications, such as voice mail notification, numeric paging, mobile terminate/originate, and mobile IP (web-based messaging), on a variety of networks. The SMSC also supports Enhanced Message Services, which includes ringtone downloads, picture messages, audio clips and contact lists.
Advantages of the SMSC
- The SMSC helps telecom operators differentiate their data messaging services
- It supports enhanced applications
- It helps increase customer satisfaction and subscriber loyalty while minimizing CAPEX/OPEX.
- It safeguards an operator’s investments and offers enhanced, IMS/LTE-compatible applications.
The SMSC supports multiple network technologies, including CDMA, IMS, TDMA, GSM and UMTS. In addition, the SMSC supports interworking among technologies for the delivery of SMS between networks. Built-in IP messaging enables single-box support for legacy networks and IMS/LTE and helps eliminate hardware proliferation.
Industries which might require a SMSC Platform
Now-a-days, most of the industries look forward to SMSC. Few of the professional groups that can definitely get benefitted with SMSC are:
- Telecom service providers
- VAS Providers
- Captive Network Providers
- System Aggregators
- Bulk SMS aggregators
Technologies under the SMSC Platform
Signaling Server – It has the receiver and the transmitter as the prime interfaces into the SS7 network. It is responsible for connecting with the MSC/HLR on the MAP layer of the SS& network.
SMS Routing – It takes care of selecting the optimal delivery path in case more than one link to SS7 connectivity exists.
SMS Filtering – It is used to decide the blacklist and White-list of MSISDN series, which helps deciding the mobile customers allowed to use the SMSC platform.
Message Queue – It is a high performance functionality, which stores the entire SMS traffic before forwarding it to the destination.
Connectivity Gateways – SMSC arrives coupled as default with SMPP and HTTP servers. The SMSC gateway pushes bulk SMS in case of A2P SMS traffic.
