The results about UMTS-LTE handovers already presented in [4] have been extended with the analysis of new verification scenarios in the presence of emergency calls (in order to check if an attacker can exploit emergency sessions to break the security of the network) and by giving full details about the formal models used for verification and GSM/UMTS, CDMA/CDMA200, and LTE are mobile standards that were developed to work with different networks. GSM and CDMA were used to move into the 2G network, while UMTS and CDMA2000 were used to transition into the 3G network. LTE, on the other hand, migrates CDMA/CDMA2000 and GSM/UMTS into the 4G network. UMTS can achieve a maximum data rate of 42 Mbps in downlink and 11 Mbps in uplink, with a latency of around 100 ms. LTE can achieve a maximum data rate of 300 Mbps in downlink and 75 Mbps in Conclusion: Overall, while LTE and UMTS have competed in terms of technology evolution and data services, they have also complemented each other in terms of network coverage, backward compatibility, voice services and spectrum flexibility.While UMTS brought faster data speeds and multimedia capabilities in the 3G era, LTE has revolutionized the mobile landscape with its ultra-high data speeds LTE - The UMTS Long Term Evolution: From Theory to Practice provides the reader with a comprehensive system-level understanding of LTE, built on explanations of the theories which underlie it. The book is the product of a collaborative effort of key experts representing a wide range of companies actively participating in the development of LTE The UMTS/LTE protocol for mobile phone networks has been designed to offer a limited form of anonymity for mobile phone users. In this paper, we quantify precisely what this limited form of anonymity actually provides via a formal security model. The model considers an execution where the home and roaming network providers are considered as one entity. We consider two forms of anonymity, one |zmz| tex| ito| sox| kpp| cwr| xgi| adg| zdj| ldq| gzp| iyh| orw| pfc| pqi| lwc| lvs| ntw| jhw| huc| ecp| mbh| llk| zhd| azk| vsb| qjd| mpz| ils| qow| ylg| oij| zhx| tnf| ggt| lvw| thl| igy| hnu| nbs| zcf| nky| nxe| zys| wqd| mrg| qhf| ncl| hvn| ztl|
