The UE sends an Attach Request containing its IMSI or GUTI (Globally Unique Temporary Identifier) to the eNodeB, which forwards it to the MME.

To protect user privacy, the network avoids sending the permanent identity (IMSI) over the airwaves whenever possible. Instead, the MME generates a temporary ID called the . The UE uses the GUTI for subsequent connections to avoid being tracked by third parties. The UE sends an Attach Request containing its
