TCP session initial setup messages that include a Maximum Segment Size (MSS) value, which controls the size limit of packets transmitted during the session. This feature involves setting this value where necessary to ensure packets are not too large for the core to transmit. This will reduce packet loss due to oversized packets arriving at the core's interfaces, and reduce the need for fragmentation and reassembly, which are costly procedures.

The SUPI (subscription permanent identifier) secret needs to be encrypted before being transmitted over the radio network as a SUCI (subscription concealed identifier). The concealment is performed by the UEs on registration, and deconcealment is performed by the packet core. You can now securely manage the required private keys through the Azure Portal and provision SIMs with public keys.
