According to some legacy, USIM pre R8 is sufficient both for LTE as well as VoLTE/RCS IMS based services and investment in LTE/IMS aware USIM/ISIM R8+ is not going to pay off. Others argue that the new USIM/ISIM R8+ is a key to exploiting the full potential of possible LTE services. During the development of the “LTE USIM/ISIM (delta)” training none of these conclusions were taken for granted. Thus, the training gives a detailed comparison of possible network deployments, procedures and services with and without the support of new LTE USIM/ISIM R8+ features. The main objective is to pass on to our participants knowledge necessary to undertake rational decision regarding support of new LTE USIM/ISIM features on UICC cards and to indicate the topics to be discussed with other network departments to avoid conflicts with operators mid- or long-term strategic plans.
The training is intended for UICC/(S)SIM engineers, who want to extend their knowledge with issues regarding new LTE/IMS related USIM/ISIM features available from R8.
