Short Message Service Centre (SMSC)

Reliable continuity & connectivity for the world’s most pervasive mobile messaging service

The Enghouse Networks SMSC ensures that the SMS services remain reliable and reachable to all subscribers connected to 2G, 3G, 4G or 5G networks. Compliant with all major industry standards, the Enghouse SMSC’s modular architecture enables you to share components, centralize functions and reduce complexity. It can also be deployed as a Virtualized Network Function (VNF).

Founded on the Enghouse Networks distributed modular architecture, our SMSC (formerly Jinny SMSC) provides industry-leading performance, high-availability, and cost-effective scalability. It also complies with all open standards that are defining the future of mobile messaging.

Enghouse SMSC enables wireless Operators to optimize their network architecture and interworking procedures by incorporating 4G IP-SM Gateway and the 5G SMSF functions directly into the SMSC, instead of within additional nodes.

Because the Enghouse SMSC connects simultaneously to the IMS and circuit-switched networks, it avoids many of the issues caused by inserting an additional IP-SM-GW node into messaging flows. It handles all interworked messages, whether they originate as SS7 or SIP/IMS, providing a central point for tracing and troubleshooting deliveries.

Challenges for Operators

As Wireless networks transition towards the all-IP network, there are great differences in the rate of change globally. Mobile Network Operators (MNOs) must ensure that subscribers can still communicate with their contacts in other networks and countries, and with VAS service providers.

Therefore, operators rolling out 4G and 5G networks must ensure that SMS continues to be supported in those networks and interworks with SMS in legacy networks.

Trendy Fragmentation

With the emergence and growth of richer communication services, SMS usage and revenues will never be what they were. However, instant messaging is trendy and fragmented. Social networks and OTT messaging services are vying to be channels for next-gen business messaging, while the more traditional eco-system is aligning around RCS.

The Old Reliable

With fragmentation in rich messaging channels and no clear commercial models, SMS is still the mainstay of business messaging and the “go-to” medium when you must get your message out or send a one-time authentication code, and even for some M2M services.

Without the revenues of the past, minimizing the cost of supporting SMS is vital. Many operators are adopting Network Function Virtualization (NFV) architecture as a means of optimizing the operation of their network, and require that all systems fit with this model.
