Support of 'LTE-M RAT type reporting to PGW' flag in the indication IE for S-GW to pass the LTE-M RAT type to P-GW.

21.28.0

Feature changes

Previous Behavior:

When MME requests the S-GW to pass the LTE-M RAT type to the P-GW, the S-GW sends the LTE-M RAT type to P-GW without receiving the LTEMPI(LTE-M RAT type reporting to P-GW Indication) bit in the indication IE from MME.

New Behavior: When MME requests the S-GW to pass the LTE-M RAT type to the P-GW, the S-GW sends the LTE-M RAT type to P-GW only if it receives LTEMPI bit in the indication IE from MME in every Create Session, Request message, and Modify Bearer Request message. Otherwise, S-GW sends the WB-E-UTRAN RAT type to P-GW.

Customer Impact: This enhancement reduces the call drop for the customer.
