the U.S. has selected the Bridgewater Home Subscriber Server (

LTE Evolved Packet Core (EPC) deployment. A Bridgewater customer since 2005,
this service provider currently deploys Bridgewater service control and
application policy solutions in its existing 3G network. With this new
implementation, Bridgewater extends its footprint to support the new 4G
network.

repository in the LTE Evolved Packet Core that contains subscriber and device
profile and state information, and supports authentication, authorization and
mobility management functions in LTE. The Bridgewater HSS supports broad
multi-vendor interoperability using standards-based interfaces with all major
network equipment vendors. Fully compliant with 3GPP Release 8 standards,
