VPN-1 MASS? Just noticed this on the software subscriptions downloads. The only download is for IPSO 4.1. From the users guide: "VPN-1 MASS is a security gateway for mobile networks. It currently supports the UMA and 3G I-WLAN architectures. This chapter describes these technologies briefly, and presents the product's main features." "3G Wireless Interworking, or 3G I-WLAN, is an architecture that allows client devices to gain access into IP hosts in the operator's network, even when connecting from the Internet. This solution caters for the needs of dual-mode devices, which can connect to a cellular Radio Access Network or to a Wi-Fi access point, depending on available reception." "UMA is an architecture that allows dual-mode phones to roam between cellular radio access and Wi-Fi access. Handovers can occur at any time, even while a call is in progress. The term "unlicensed" refers to the radio spectrum being used in Wi-Fi, which does not require licensing in contrast to the spectrum used by cellular (GSM, UMTS) networks." Pretty interesting stuff!
