Wi-Fi Calling and the Support of IMS Services over Carrier Wi-Fi Networks
ثبت نشده
چکیده
Carrier Wi-Fi deployments are helping mobile operators take advantage of already deployed evolved packet core (EPC)-based services for supporting trusted Wi-Fi access networks. Approaches include reusing P-GW -based accounting, policy enforcement, and regulatory services for supporting Wi-Fi users. With Wi-Fi calling, similar EPC-based services can be used to support IMS-based rich media services accessed over untrusted Wi-Fi networks.

متن کاملWi-Fi (2.4 GHz) affects anti-oxidant capacity, DNA repair genes expression and apoptosis in pregnant mouse placenta
Objective(s): The placenta provides nutrients and oxygen to embryo and removes waste products from embryo’s blood. As far as we know, the effects of exposure to Wi-Fi (2.4 GHz) signals on placenta have not been evaluated. Hence, we examined the effect of prenatal exposure to Wi-Fi signals on anti-oxidant capacity, expressions of CDKNA1, and GADD45a as well as apoptosis...
