Seamless Roaming Nears Reality

Fixing Roaming Woes

The 3GPP's voice-call-continuity standard aims to plug holes between  
cellular and Wi-Fi networks and drive availability of SIP-based dual- 
mode handsets. But VCC, at least in its first iteration, falls short  
in addressing key enterprise features.

Be careful what you ask for. Enterprises have long wanted dual-mode  
Wi-Fi cellular phones to cut phone bills with the convenience of a  
single device. Carriers have had nothing to gain from that; in fact,  
North American wireless carriers have discouraged handset makers from  
developing Wi-Fi-enabled handsets and have gone out of their way to  
offer customized versions without Wi-Fi.

Now enterprises are going to get what they've asked for--sort of. A  
new plan will let enterprise users continue with a single device, but  
carriers won't lose those precious minutes. The VCC (voice-call  
continuity) initiative promises to provide seamless roaming between  
cellular and Wi-Fi networks, letting mobile phone users access the  
office network for mobile services  . . .
