we interface the gsm module to esp uart .
I able to data transfer to cloud using wifi with default mqtt library .
So we interfaced gsm module to esp uart .
with traditional at command i able to get the network and ip address .

how to link the ip address or tcp method got from my gsm module to esp module . and use default mqtt library to send data to cloud.
I dont want to use ppos method . because i dont have knowledge exposure on ppos method .

You mean you want to use the TCP/IP stack in your GSM module instead? That would imply re-writing the entire TCP/IP middle layer, or implementing your own MQTT client, specifically for that communication method. Strongly suggest you instead acquire knowledge of pppos instead.
