Hi Irfan Ali, That is very informative video about LTE Attach process. I have some questions If eNB is on 10.40.50.0/24 subnet and Mehmet is on 10.40.40.0/24 subent, then How does eNB know packet is destined for Mehmet? Or How does it route the packet to Mehmet on its IP address over DRB? Is the IP address to Mehmet being assigned by PGW dynamically? If possible can you explain how is that IP address getting assigned to Mehmet?

The eNB does not look inside IP packet of the UE at all. During the attach procedure GTP-U tunnel is setup from PGW to SGW and from SGW to eNB. For each UE there is a different downlink TEID on the SGW-> eNB GTP-U tunnel. Any packet that comes on this TEID is destined for Mehmet and eNB will send this to Mehmet. The IP@ allocated to PGW can either be dynamic or static if the HSS provides this IP@ for the UE via the MME.

Hi, Thanks for very clear explanation... Can you plese clarify, how ayesha would know the ip address of mehmet(ip_m), as ayesha may be having only phone number of mehmet.Which module would handle that
@IrfanAli-nz7mb

Hi Likhitha, Ayse finding Mehmet's IP address can occur in various ways which are specific to the application that Ayse is using. For example, for Skype, there is registry that keeps track of IP_m and provides it to Ayse's skype client. Typically this is the scheme used. This is all done in the application itself and Ayse does not need to enter IP_m or even know about IP_m.
