2 doc.: IEEE 802.11-01/635r1 Submission November 2001 Peter A. Dahl, Verizon WirelessSlide 2 3G ≠ UMTS First things first….

3 doc.: IEEE 802.11-01/635r1 Submission November 2001 Peter A. Dahl, Verizon WirelessSlide 3 There is an alternative… CDMA2000 1xRTT –1xRTT – utilizes same spectrum as IS95 CDMA (1.25MHz) –1xRTT – has double the voice capacity of IS95 CDMA. –1xRTT – meets ITU criteria for a 3G standard. –1xRTT – peak burst rate 153.6Kbps (typical 40-60Kbps). –1xRTT – includes Mobile IPv4 as part of the specification. –Evolution Path 1xRTTRelA – peak burst rate 307.2Mbps. 1xEVDO – peak burst rate 2.4Mbps. 1xEVDV – peak burst rate 2.4Mbps, and double the voice capacity. 3xRTT – same spectrum needs as UMTS (5MHz), equivalent data throughput.

4 doc.: IEEE 802.11-01/635r1 Submission November 2001 Peter A. Dahl, Verizon WirelessSlide 4 Standards and Carriers… Standards Bodies –3GPP2 – actually do the work. –EIA/TIA – rubber stamp and publish the docs. –CDG – specify interoperability criteria. Carriers –US: Verizon Wireless, Sprint PCS. –Asia: KDDI, SK Telecom, China Unicom. –Europe: Ukraine ?

6 doc.: IEEE 802.11-01/635r1 Submission November 2001 Peter A. Dahl, Verizon WirelessSlide 6 Mobile IP registration Once a MN has requested Mobile IP service and received an Agent Advertisement message, it must perform Mobile IP registration. The RRQ and RRP comprise the Mobile IP registration process Registration Takes place through a two message exchange: FA HA AAA MN 1 2 3 4 4 (1)MN sends Registration Request Message (RRQ) to FA (2)FA authenticates the MN by sending an Access Request Message to the AAA upon receiving RRQ. (3)If AAA authenticates MN, the RRQ is passed onto the HA. (4)The HA responds with a Registration Reply Message (RRP).

7 doc.: IEEE 802.11-01/635r1 Submission November 2001 Peter A. Dahl, Verizon WirelessSlide 7 Return data path WLAN and CDMA2000 – Key Enablers ? HA AAAh 1xRTT Home Network Foreign WLAN Network PDSN 1. “PDSN-lite” PDSN functionality for WLAN connected MNs AP 2. Mobility Client Interface and mobility management (MIPv4) Outgoing data path IEEE 802.11a/b/g

8 doc.: IEEE 802.11-01/635r1 Submission November 2001 Peter A. Dahl, Verizon WirelessSlide 8 Some Goals… Seamless roaming (no user interaction). One pass authentication (standards necessary ?). Robust encryption on the “local link”. International capability (.11 is 3G agnostic). WLAN (actually link layer) agnostic. Single carrier can’t own a significant number of hot- spots, so roaming agreements will be required.
