UMTS User equipment

The UMTS standard does not restrict the functionality of the User Equipment in any way. Terminals work as an air interface counter part for Node-B and have many different types of identities. Most of these UMTS identity types are taken directly from GSM specifications.
  • International Mobile Subscriber Identity (IMSI)
  • Temporary Mobile Subscriber Identity (TMSI)
  • Packet Temporary Mobile Subscriber Identity (P-TMSI)
  • Temporary Logical Link Identity (TLLI)
  • Mobile station ISDN (MSISDN)
  • International Mobile Station Equipment Identity (IMEI)
  • International Mobile Station Equipment Identity and Software Number (IMEISV)
