How can I download the slides for Network Architecture for LTE and Wi-Fi Interworking

Hello Luay,

You can download the slide by clicking top right "pdf icon" (as shown below) after login with your credential.

Thanks,

Any update regarding iOS8 and WiFi Calling ?

Q: Is MOBIKE support needed for WiFi-LTE interworking?
Is this needed even for handover within the wifi network too, i.e. moving between APs??

A: UE can use MOBIKE to inform ePDG about change of UE’s IP address (assigned by wifi network, not by PGW)
for existing IKE/IPsec tunnels without IKE re-establishment.
(IP address change can be occurred when UE moves from one AP to another AP in wifi area)
 
Without MOBIKE, UE have to re-establish IKE/IPsec tunnels with updated IP address after moving to another AP
this procedure just seems as re-attachment of UE (re-attachment is not a handover)  
 
Here is answer for you:
1. Needed for handover within the wifi network? Required
2. Needed for wifi-lte handover?
Not required if UE moves ”LTE -> WiFi AP -> LTE” 
But required if UE moves “LTE -> WiFi AP #1 -> WiFi AP #2 -> LTE” 

interesting, didatic and inspiring presentation; as usual Netmanias.
I´d like to know what is your vision about the more efficient way to implement traffic steering based on radio or congestion conditions; I mean, select the path (3GPP or WIFI) with less RTT at any moment. 
Many thanks

Thank you very much for your compliment! We will try to cover that sometime.
