2. Signaling is growing 50% faster than data traffic
in Evolved Packet Core
LTE network requires 50-80%
more signaling compare to
2G/3G network
Signaling requirements are driven by flat architecture and network deployment.
Service awareness and differentiated charging contributes to overall transaction requirements

12. Optimize the Traffic and Monetize Your Network
Compared to a standalone solution, the integrated IP Edge option, provisioning In-Line Services on a single platform, represent s the
most efficient and cost-effective way for mobile operators to optimize and monetize their networks. The integrated approach cre ates
new revenue streams, simplifies network topology and management, and lowers OPEX and CAPEX.
