LTE (Long-Term Evolution) of UMTS (Universal Mobile Telecommunications Service) is one of the latest steps in an advancing series of mobile telecommunication systems.
LTE was and is standardized in parallel to other radio access network technologies like EDGE (Enhanced Data Rates for GSM evolution) and HSPA (High-Speed Packet Access). This means that LTE is not a simple replacement of existing technologies. Rather it is expected that different kinds of radio access will coexist in operator networks.
Indeed, one of the major challenges of LTE signaling analysis will concern the analysis of handover procedures. Especially, the options for possible inter-RAT (Radio Access Technology) handovers have multiplied compared to what was possible in UMTS Release 99. However, also intra-system handover and dynamic allocation of radio resources to particular subscribers will play an important role.
