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.

Thank you for visiting Netmanias! Please leave your comment if you have a question or suggestion.
