3G ≠ UMTS First things first… . Subside A. Dahl, Verizon Wireless

There is an option… CDMA2000 1xRTT – uses same range as IS95 CDMA (1.25MHz) 1xRTT – has twofold the voice limit of IS95 CDMA. 1xRTT – meets ITU criteria for a 3G standard. 1xRTT – top burst rate 153.6Kbps (run of the mill 40-60Kbps). 1xRTT – incorporates Mobile IPv4 as a major aspect of the particular. Development Path 1xRTTRelA – crest burst rate 307.2Mbps. 1xEVDO – crest burst rate 2.4Mbps. 1xEVDV – top burst rate 2.4Mbps, and twofold the voice limit. 3xRTT – same range needs as UMTS (5MHz), identical information throughput. Dwindle A. Dahl, Verizon Wireless

Standards and Carriers… Standards Bodies 3GPP2 – really take the necessary steps. EIA/TIA – elastic stamp and distribute the docs. CDG – determine interoperability criteria. Bearers US: Verizon Wireless, Sprint PCS. Asia: KDDI, SK Telecom, China Unicom. Europe: Ukraine ? Diminish A. Dahl, Verizon Wireless

Mobile IP enrollment Once a MN has asked for Mobile IP benefit and got an Agent Advertisement message, it must perform Mobile IP enlistment. Enlistment Takes put through a two message trade : MN sends Registration Request Message ( RRQ ) to FA validates the MN by sending an Access Request Message to the AAA after getting RRQ. On the off chance that AAA verifies MN, the RRQ is passed onto the HA. The HA reacts with a Registration Reply Message ( RRP ). 4 3 HA 4 FA 2 1 AAA MN The RRQ and RRP involve the Mobile IP enrollment prepare Peter A. Dahl, Verizon Wireless

Portability Client Interface and versatility administration (MIPv4) Peter A. Dahl, Verizon Wireless

Slide 8

Some Goals… Seamless wandering (no client association). One pass verification (gauges important ?). Strong encryption on the "nearby connection". Worldwide ability (.11 is 3G freethinker). WLAN (really interface layer) rationalist. Single bearer can\'t claim a noteworthy number of problem areas, so meandering assentions will be required. Diminish A. Dahl, Verizon Wireless
