name: 5G-GUTI
full_form: 5G Globally Unique Temporary Identifier
context: To avoid possible paging occasion collision and to enhance the likelihood that paging is received successfully for different USIMs, a Multi-USIM UE may need a new 5G-GUTI to modify the timing of the Paging Occasions (POs) for a USIM when the USIM's registration is not emergency registration. When a Multi-USIM UE needs a 5G-GUTI assignment, it performs a Mobility Registration Update without any specific indication (i.e. it is using a normal Registration procedure). This triggers the AMF to allocate a new 5G-GUTI and provide it to the Multi-USIM UE in the Registration Accept message. NOTE: It is recommended to avoid excessive signalling load from UE due to this procedure.
description: The 5G Globally Unique Temporary Identifier (5G-GUTI) is a unique identifier assigned by the Access and Mobility Management Function (AMF) to a Multi-USIM User Equipment (UE) for modifying the timing of Paging Occasions (POs) when the UE's registration is not an emergency registration. This identifier plays a crucial role in avoiding possible paging occasion collisions and enhancing the likelihood of successful paging reception for different Universal Subscriber Identity Modules (USIMs).
explanation: The 5G-GUTI is classified as an Identifier because it serves as a unique code assigned to a UE for specific purposes, such as modifying Paging Occasions timing. This identifier is used within the context of the 3GPP's specifications for efficient network operations and management.
