Its just an echo request/response message exchange to maintain a gtp tunnel between tunnel endpoints.

Periodic echo requests are sent to all GTP peers, If the gtp peer doesnt respond to echo request messages with a time period (some timer) then its considered dead and subscribers are moved to another GW.

Hi Saurabh, is it necessary to move subscribers to another SGW always ?

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 ?
