+NSOSTR timeout

What is the maximum time to receive a +NSOSTR response?

If the UE establishes a UDP service, its response time is very fast. However, if it uses a TCP service, it needs to wait for the server’s response, and the longest possible time could be approximately 2 minutes.

I use TCP

Can you guide me in the direction where you have the information regarding the approximately 2 minutes?

The simulation of this event might be quite challenging. It requires the server to be able to establish a normal TCP connection, but to prohibit receiving messages or to not respond ACK after receiving the messages.
