Option 1: Only International Mobile Subscriber Identity (IMSI)
Option 2: Either International Mobile Subscriber Identity (IMSI) or International Mobile Equipment Identity (IMEI), depending on the UE's capabilities
Option 3: Both IMSI and IMEI simultaneously, regardless of the UE's capabilities
Option 4: Neither IMSI nor IMEI; other identification parameters are used

These parameters can include either the International Mobile Subscriber Identity (IMSI) or the International Mobile Equipment Identity (IMEI), depending on what is supported by the UE and required for the EPS service.
