Broadly interoperable with industry leading IPSec VPN gateways it gives secure mobile access to corporate email, intranet content and enterprise applications.

Certicom UMA Device Software provides the core functionality that is required by mobile devices implementing UMA capabilities.

UMA:
Unlicensed Mobile Access (UMA) addresses the Fixed Mobile Convergence (FMC) market by enabling a mobile device to access the core of a cellular network using an IP connection that is secured by a standard IPSec VPN. UMA provides the mobile device with the exact same feature set that is available when the mobile device is using the standard GSM cellular connection.

More detailed explanation:
1. A mobile subscriber with a UMA-enabled, dual-mode handset moves within range of an unlicensed wireless network to which the handset is allowed to connect.
2. Upon connecting, the handset contacts the UMA Network Controller (UNC) over the broadband IP access network to be authenticated and authorized to access GSM voice and GPRS data services via the unlicensed wireless network.
3. If approved, the subscriber’s current location information stored in the core network is updated, and from that point on all mobile voice and data traffic is routed to the handset via the Unlicensed Mobile Access Network (UMAN) rather than the cellular radio access network (RAN).
4. ROAMING: When a UMA-enabled subscriber moves outside the range of an unlicensed wireless network to which they are connected, the UNC and handset facilitate roaming back to the licensed outdoor network. This roaming process is completely transparent to the subscriber.
5. HANDOVER: If a subscriber is on an active GSM voice call or GPRS data session when they come within range (or out of range) of an unlicensed wireless network, that voice call or data session can automatically handover between access networks with no discernable service interruption. Handovers are completely transparent to the subscriber.
