This review paper presents within a common framework the mobile station positioning methods applied in 2G, 3G, and 4G cellular networks, as well as the structure of the related 3GPP technical specifications. The evolution path through the generations is explored in three steps at each level: first, the new network elements supporting localization features are introduced; then, the standard localization methods are described; finally, the protocols providing specific support to mobile station positioning are studied.
Cellular Communication has become an important part of our daily life. Besides using cell phones for voice communication, we are now able to access the Internet, conduct monetary transactions, send text messages etc. However, the wireless medium has certain limitations over the wired medium such as open access, limited bandwidth and systems complexity. These limitations make it difficult although possible to provide security features such as authentication, integrity and confidentiality. The current generation of 3G networks have a packet switched core which is connected to external networks such as the Internet making it vulnerable to new types of attacks such as denial of service, viruses, worms etc.

UMTS uses wideband code-division multiple access W-CDMA radio access technology to offer greater spectral efficiency and bandwidth to mobile network operators. These speeds are significantly faster than the 9. The first national consumer UMTS networks launched in with a heavy emphasis on telco-provided mobile applications such as mobile TV and video calling. While they suggest covering just a channel access method namely a variant of CDMA , they are actually the common names for the whole air interface standards. It supports conventional cellular voice, text and MMS services, but can also carry data at high speeds, allowing mobile operators to deliver higher bandwidth applications including streaming and broadband Internet access.
Не понимаю, - сказала. - Мы же говорим не о реверсии какой-либо сложной функции, а о грубой силе. PGP, Lucifer, DSA - не важно.
Итак, кольцо взял немец. - Верно. - Куда он делся. - Понятия не имею. Я побежал позвонить в полицию.
Глаза Беккера расширились. - Ты его. Двухцветный равнодушно кивнул. - Где оно? - не отставал Беккер.
