Hi ,

As per my understanding S1AP will use heart bet mechanism to detect an Link failure and re establish the connection if required.
Hear beat mechanism means they will exchange some beat packets to monitor the link.

LTE: What does mean by fully qualified tunnel id (FTEID) in GTP control messages ?

I have seen GTP control messages and found that F-TEID consists of an IP address and 32 bit long Tunnel Id. For example: Create Session Response message contains control plane F-TEID and user plane F-TEIDs. I have a question here, why not only TEIDs are included in Create Session Response message when IP address would be common ? or Does it mean control and user plane both F-TEIDs may have different IP address ?
