for an active UE to which DL and UL Data transmiting/receiving, if measurement gap subframes hit then where UL/DL data should be buffered and how it should maintain?

I didn't observed the behavior of data buffering during the period of measurement gap. But logically it should be at RLC layer during this period since MAC layer already knows data is not going to be scheduled on particular sub frames.

In LTE handover procedure, after UE handover to the target cell, if new TAI is not in the TAI list, the TAU will be triggered.

In HO procedure, UL/DL data has been handover to the target cell.

But before TAU, the UE doesn't register to the new MME, in the new cell, how the the DL/UL data transfer between UE and network(S-GW / P-GW) before TAU and after HO.

Also, as we know, if the TAU fails, the DL/UL data transfer will be interrupted, which network element will release the DL/UL throughput?

for efficient utilisation of resources to schedule i need some clear references about measurement gaps implementation in MAC layer wise. please provide references including specification versions.
