| UMA Feature |
Operator Advantage |
| Fastest, easiest path to standardization |
UMA is a proven RAN gateway interface. The UMA/GAN specification supports Iu today.
In this market, time-to standardization is time-to-market, and UMA is the clear winner.
|
| Un-matched investment protection |
UMA supports more than a single 3G femtocell application. Operators can leverage installed UMA infrastructure to support 3G and 2G Dual-Mode Handset (DMH) services, as well as applications like fixed-line VoIP and softmobile clients. |
| Purpose built for Internet service delivery |
The public Internet is un-managed, un-secure, and bandwidth constrained. UMA was purpose built to operate in this environment. A light-weight, low bandwidth protocol, UMA supports 3GPP recognized security (IPSec, IKE v2, EAP-SIM, EAP-AKA) with built-in RTP redundancy. |
| Proven femtocell authentication, registration |
The UMA protocol has a proven 'discovery and registration' process required for zero-touch consumer deployments of femtocells. |
| Proven scalable access over IP |
Mobile operators have proven UMA delivers scalable, secure access to the core service network over the Internet to hundreds of thousands of end-points today. |
| Extensible user access controls |
UMA has an extensible user access mechanism for operators to control and manage which subscribers/SIMs can access which services from which femtocells located worldwide. |
| Cell planning and mobility management |
UMA has already addressed the challenges of cell planning for overlay networks. UMA has a proven approach for overcoming cell planning complexities and mobility management. |
| Regulatory compliance |
UMA has developed mechanisms for supporting regulatory issues like lawful intercept and emergency calling. |
