Increased capacity

SS7-over-IP networks offer increased capacity. The bandwidth overall is greater, both due to inherent capacity and to dynamic bandwidth sharing. Data traffic, including Short Message Service (SMS), can run more efficiently over SIGTRAN. For example, SMS data is saturating some SS7 networks. Using devices such as the EAGLE with its gateway functions, operators can have a Short Message Service Center communicate directly to Home Location Registers (HLR) and Mobile Switching Centers (MSCs) using SIGTRAN.

Flexibility

SIGTRAN uses the packet IP network to define logical connections between devices. Because the network developers, planners, and installers are no longer tied to deploying fixed circuits for signaling, they have the flexibility to define the network as needs and demands change. Flexibility is key in adapting bandwidth on demand; redimensioning the SS7-over-IP network can be done completely through software. With legacy SS7, users are limited to either 56 or 64 kbps links.

There is also flexibility when adding capacity for new IP-based solutions and value-added services; future enhancements are more transparent.
