1xEV-DO Network Architecture

1xEV-DO is a new air interface protocol optimized forPacket Data

1xEV-DO is using the Wireless IP data network model thatis different from IS-41 network model used for existingcdmaOne (IS-95) and cdma2000 (IS-2000) networks

1xEV-DO uses new Radio Access Network (RAN) that

provides the 1xEV-DO air interface and also interfacesdirectly to Packet Data Serving Node (PDSN) via R-P (A10-A11) interface

Provides Mobile IP or Simple IP access based on AccessTerminal (AT) and PDSN capabilities

Accounting, Authentication and Authorization (AAA)server contains all 1xEV-DO subscriber information

1xEV-DO Access Terminal (cont.)

Currently using Qualcomms Hornet 2 and Chester Prototype

Access Terminals (AT)

ATs support an Ethernet interface to a laptop PC for dataapplications

Several Ethernet connections can be served via one Hornet

The Hornet uses pre-configured IP addresses to identify itself

to the network and AT during registration

The Hornet & Chester receivers are dual diversity antennas

Relay or Network model

We note that at this time key commercial product version ofthe terminals are under development

1xEV-DO Handoff Scenarios

Active State Handoff Forward Link (FL):

Forward Link Is Transmitted in Simplex Mode

Access Terminal (AT) Selects the Strongest Leg From the Active Set and the Data RateThat It Can Support Via the Data Rate Control (DRC) Channel.

Indicates from which sector it will select the strongest signal; DRC on Reverse Link willindicate from where it will need what data rate.

The Same Active Set Is Defined for Both Forward and Reverse Link

Reverse Link (RL)

Softer Handoff - All Sectors Are in the Same Cell

Soft Handoff - Different Cells: Intra 1xEV-DO FMS

Cells Connected to the Same 1xEV-DO FMS

Inter 1xEV-DO FMS

Cells Are Connected to Different 1xEV-DO FMS

Dormant State Handoff Inter-PCF Handoff

Retains Connection to the Same PDSN When the AT Crosses

the Subnet (FMS) Boundaries While in Dormant Mode
