Wireless CDMA000 1xRTT and EV-DO networks. The ollowing private network-related areas are

described:

n CDMA000 1xRTT and EV-DO technologyn Enhancements that Verizon Wireless oers on its networkn Options available to cstomers sing private networks

This paper begins with an overview o CDMA000 1xRTT and EV-DO technology that provides scient

inormation or any reader who simply wants a high-level nderstanding o a CDMA network. The

paper will then explore in detail the Verizon Wireless private network soltions that se the network,and available cstomer options.

1.1 Aiee

This paper has been developed or enterprise cstomers, IT administrators, decision makers, and other

personnel. It is assmed that the reader has an nderstanding o CDMA000 1xRTT and EV-DO

technology and some nderstanding o compter and network concepts.

2. cdMA2000 1xrtt And EV-do nEtWorK And

tEcHnoLoGY oVErVIEWOver time, more and more demands have been made on the capabilities o corporate networks.

Workers want more mobility, high-speed access, and an extension o applications across the enterprise,

all o which can strain crrent IT capabilities.

Verizon Wireless nderstands these demands and has constantly improved its mobile data network to

oer increased mobility, access, and applications. This process is ongoing, bt it pays to see whats

happened beore to gain a greater appreciation o the capabilities o todays mobile data network.

Early second-generation (G) CDMA-based wireless networks have proved their eectiveness in

delivering high-qality voice trac to sbscribers. These early G networks were known as cdmaOne

or IS-95 ater the interim standard that dened cdmaOne.

Shortly thereater, voice sers wanted basic data services, which prompted the varios indstry players

to join together to meet this demand. A set o global wireless data standards and specications was

developed to dene the methods and techniqes reqired to oer circit-switched data services to

sbscribers. These methods and standards ormed the basis or third-generation (3G) wireless

commnication and are dened by a set o independent International Telecommnications union

(ITu) recommendations. These ITu recommendations or CDMA networks are collectively known asthe International Mobile Telecommnications-000 (IMT-000) standards ramework.

In 000, the IMT-000 standards ramework was implemented on a CDMA wireless network,

becoming the very rst commercially available, 3G circit-switched data service to be deployed

based on these global standards. On CDMA networks, these 3G data services are typically reerred to

as CDMA000 or IS-000.

The CDMA000 wireless air interace standard is known by many terms, inclding: 1x, 1xRTT, IS-000,

CDMA000 1x, and CDMA000. The designation 1xRTT is reqently sed to identiy the version o

CDMA000 radio technology that operates over 1.5-MHz radio channels (one times 1.5 MHz).

The rst phase o CDMA000 is called 1xRTT. 1xRTT almost dobles the voice capacity over IS-95networks and provides basic data services conorming to the IMT-000 standard or uMTS (universal

Mobile Telecommnications System) services, delivering data at near-broadband speeds over

mobile wireless commnications networks. 1xRTT provides maximm theoretical data rates o

144 Kbps (downlink) and 144 Kbps (plink), as well as twice the voice capacity on a single 1.5-MHz

CDMA channel.

The next phase o CDMA000 is called 1xEV-DO (Evoltion Data Optimized) and increases the downlink

maximm theoretical data rate to .4 Mbps. The average data rate a ser experiences is a theoretical

rate o 400 to 700 Kbps. 1xEV-DO Revision A (Rev. A) spports Qality o Service (QoS), converges IP

services and VoIP, redces latency, increases the maximm theoretical downlink speed to 3.1 Mbps,

and boosts the maximm plink speed to 1.8 Mbps. Typical average download speeds or Rev. A are600 Kbps to 1.4 Mbps and typical average plink speeds are 500 Kbps to 800 Kbps. The entire Verizon

Wireless EV-DO network has now been pgraded to spport Rev. A.

As new technologies emerge or wireless commnications, Verizon Wireless is stdying and considering

these technologies and contining to improve its ability to oer more mobility, more secre network

access, and extended applications.

2.1 Mbile Sais

In a typical network setp, most sers experience a data network throgh their handhelds or throgh

modems and data cards in their laptop compters. This is the sbscribers point o entry or mobility,

network access, and enterprise-wide applications or sing corporate data. In terms o the network,handhelds or modems are the mobile stations that nction as a mobile IP client in a CDMA000 1x

and EV-DO network. Mobile stations consist o a radio, baseband processor, and a general-prpose

processor or interacing to the handset ser or to a hosting compter.

The mobile station radio and baseband processor interact with the access network (AN) to obtainradio resorces in order to exchange packet data. The mobile station tracks radio resorce stats states

sch as active, standby, and dormant. The mobile station also accepts packets rom the hosting

compter when radio resorces are not available or cannot spport data fow to the network.

2.2 Aess newk

The AN is the sbscribers entry point into the mobile network. Its here that the Verizon Wireless

mobile data network diers rom a typical network setp. This part o the mobile network is responsible

or delivering packet services or 1xRTT and 1xEV-DO connections, making it possible or sers to

expand their mobility, enjoy better access, and deploy enterprise-wide applications.

The AN maps the mobile station to a niqe link layer sed to commnicate with the Packet DataServing Node (PDSN) in the core o the network. The AN mst validate the mobile station or service

and maintain the commnications link between the mobile station and the network core. This process

greatly enhances the overall secrity o the network. The AN comprises the ollowing key elements:

Base Transceiver Station The base transceiver station (BTS) is physically composed o antennas, towers, and sophisticated

electronics. These all work together to control the air link and act as the interace between the network

and mobile stations.

Radio resorces are also managed by the BTS. Radio resorces inclde the radio reqency and channel

assignment or each mobile station, the power level o transmit and receive signals, antenna sector

assignments, and signal separation.

The BTS manages back-hal connections to the base station controller (BSC) in order to minimize

redndant trafc and trafc delays. The commnications protocols sed between the BTS and BSC

are proprietary.

Base Station Controller

The BSC acts as a link or voice and packet-switched data messages between mltiple BTS nits. The

BSC is also responsible or mobility management and handos between BTS nits that are within its

domain. It handles the overall call control process. The BSC connects to the core o the network sing

connectivity options that vary depending on whether it is voice, data, or signaling inormation.

Packet Control Function

The packet control nction (PCF) rotes IP packets between the mobile stations connected to its

associated BTS nits and PDSN. The PCF maintains the connection state between the access network

and the mobile stations. This connection state ensres an active path or packet data, bers packets

when radio resorces are not available, and relays packets between the mobile stations and the PDSN.

2.3 ce newk

The role o the core network is to act as the gateway between the access network and the pblic or

private networks that will handle the packet data. It provides connectivity athentication, athorization,

and acconting (AAA) services, acts as the gatekeeper or access to hosted and other network services,

and manages IP addresses. These nctions contribte to the overall ability o the network to oer

sers mobility and secre access, and to extend applications across the enterprise.

The core network comprises the ollowing key elements:

Packet Data Serving Node

The PDSN services the access network and acts as the primary gateway into the pblic or private

network, granting sers secre access to network data and applications.

The PDSN manages the interace between the BSC/BTS and the IP network by establishing and

terminating the mobile client link-layers. The PDSN terminates mobile station PPP services or the

mobile stations it services. It provides IP services or the mobile stations based on the services reqested

and athorized.


7/20

Each PDSN spports simple IP (SIP). When SIP services are provided to the mobile station, the PDSNacts as a stand-alone network access server (NAS) and can provide SIP services to the mobile station.

The PDSN athenticates sers locally, or it can orward athentication reqests to the AAA server and

home agent to when sers move rom one PDSN to another spport SIP.

The PDSN records packet billing inormation in coordination with the BSC and actively manages

subscriber services based on the user profle inormation it receives rom the services and AAA servers.

The PDSN rotes packets to the external pblic or private networks or to the home agent (HA), which

can be secred via secre Generic Roting Encapslation (GRE) tnnels.

3.5 IP Aessig opis

3.6 Mbile IP

Mobile IP (MIP) is an Internet protocol designed to spport host mobility. Its goal is to enable the host

to stay connected to the Internet regardless o its location. MIP is able to track a mobile host withot

needing to change the mobile hosts long-term IP address.

The evoltion o MIP secrity began with the CDMA000 Mobile IP standard. This standard was

designed to incorporate cryptographic keys or network secrity. However, the drawback was that

Dynamic IP Enables the home agent to assign a random address rom a generally

available pool provided by enterprise cstomers to mobile endpoints.

Pblic and private IP addresses Enterprise cstomers can speciy any desired range o pblic or private IP

the CDMA000 standard didnt provide a means to distribte MIP keys to mobile devices in asecre and efcient manner. To that end, Verizon Wireless implemented the Dynamic Mobile IP

update (DMu) standard. The DMu standard allows manactrers to embed pblic RSA encryption

keys into mobile devices to enable secre distribtion o MIP keys. Adopting this standard has

generated a nmber o benets that enhance overall network secrity. The DMu standard enables

stronger cryptographic keys18-bit athenticationand stronger athentication o MIP

registration messages.

3.7 dmai name Sysem

When cstomers sbscribe to Verizon Wireless private network service, enterprise trafc is passed

to the CPE (cstomer premise eqipment) at the end o the data tnnel, so DNS reqests mst

receive special attention. Normally, a sbscriber device is given a Verizon Wireless pblic DNSaddress by the HA dring PPP negotiation. In an enterprise context, a Verizon Wireless DNS cannot

be reached rom the enterprise network; thereore, it cannot complete name resoltion or the

enterprises internal domains. Once a Verizon Wireless private network service sbscriber is attached

to the tnnel, then all tracinclding DNS reqestswill be sent to the enterprise CPE roter.

Internet access will only be allowed via proxy server. All Internet access mst be done via an enterprise-

owned proxy server. The address o this proxy server mst be advertised back to Verizon Wireless.

Internet access withot a proxy server will not work. Cstomers mst ensre that all applications

accessing the Internet se the proxy server.

a private, direct connection between the enterprise network and the Verizon Wireless broadband network.

A direct connection into the Verizon Wireless broadband network lets companies commnicate with

their mobile workorces with improved data response times, while redcing concerns over secrity

and reliability. This section discsses connectivity considerations and explains all connectivity options

available and IP addressing schemes to help the reader make inormed decisions when planning and

4.1 newk AhieeA direct-connect circit can be established to the Verizon Wireless broadband data network rom any

enterprise network throgh a variety o common wireline connection types. These wireline connection

types are labeled in Figre 6 as a direct circit and rn between the enterprise network and the Verizon

Wireless broadband data network.

With Verizon Wireless connectivity and data transport soltions, corporate cstomers can bring direct

circits into the core network throgh VPN, rame-relay, T1 direct, or Mlti-link Point-to-Point Protocol

(MLPPP) connections. These network access options will be covered in mch more detail in a

sbseqent section o this white paper.

4.2 Beefs Implemeig diecii ceisDirect-circit connectivity into a trsted providers network core is an eective way or companies to

improve data response times and redce latency to mobile sers being serviced by the wireless

network. Overall connection reliability improves with direct-circit connections, becase companies

have a direct connection to the Verizon Wireless broadband network and avoid having to traverse the

Internet. As a reslt, secrity threats are more contained. Verizon Wireless oers secre, reliable, and

fexible access to its networks. Enterprise data is one o a bsinesss most important assets and mst

be kept secre. FECS access provides enhanced privacy and secrity becase the direct circits are not

4.3 ceiviy opisVerizon Wireless has a variety o connectivity options or creating the connection between the

enterprise network and the Verizon Wireless broadband network. Organizations can attach to the

Verizon Wireless broadband network via VPN over Internet, single-rame relay, dal-rame relay, or

mltiple direct circits. The best option depends largely on the organizations reqirements or secrity,

cost, and redndancy. The ollowing chart illstrates the spported connectivity soltion options.

VPN connections

A VPN is a private network that ses a pblic network sch as the Internet to connect sers or remote

sites together in a secre manner. VPN direct-connect soltions are extremely poplar de to their lowcost to deploy. Instead o sing a dedicated connection sch as leased-line direct circits, the VPN

option ses tnnels roted over the Internet rom the companys private network to the Verizon

Wireless network operations center. VPN tnnels are terminated by the Verizon Wireless VPN gateway.

This approach ses a bsinesss existing connection to the Internet and reqires IPSec-compliant VPN

gateway eqipment at the enterprise location. The Verizon Wireless VPN option secres the

commnication path between the enterprise location and the Verizon Wireless network operations

center. unlike a client-to-server soltion, it does not secre the complete path rom the mobile device

to the enterprises VPN gateway. However, a VPN soltion does not oer the typical reliability andcontrolled redndancy o leased-line direct connections.

IPSec protocol

Verizon Wireless VPN soltion ses IPSec, an IETF standard protocol or TCP/IP trac secrity, to create

a secre tnnel between the enterprise and Verizon Wireless VPN gateways. IPSec protocols

athenticate the host compter, maintain data integrity, and encrypt data and shared keys. In IPSec

tnnel mode, the entire IP packet is encrypted. This does not mean that the connection between the

enterprise and the client is encrypted, bt that the connection between the enterprise and the Verizon

Wireless POP is encrypted.

Single-frame relay

Frame relay is a data connection method where the telecommnications connection is established

sing a permanent virtal circit (PVC). This PVC is a commnications path that maps the physical

circit at the cstomer site to the physical circit at the Verizon Wireless site. Frame relay is a poplar

option becase it oers garanteed bandwidth and accommodates spikes in trac when the

demand or bandwidth sddenly increases. Frame-relay circits are available rom ractional T1 data

rates starting at 56 Kbps and can approach DS-3 rates o 45 Mbps.

T1 direct

T1 direct telecommnication circits are also available. An installation ee is typically associated with

this type o connection, based on the distance between the enterprise network and the closest Verizon

Wireless POP. Fees are also infenced by local and long distance carrier rates or this service. This

option is typically sed when rame-relay services are not available locally or when long distances are

not reqired. DS-3 direct circits are available to cstomers on a case-by-case basis in certain areas.

Dual-frame relay

To rther enhance network reliability, consider creating redndancy with a dal-rame relay

connection. Dal circits are typically established between two geographically dierent locations and

provide redndant connections to redndant hardware (roters). Dal-rame relay circits are poplar

when residency and drability o the connection are desired.

Multiple direct

Verizon Wireless also spports MLPPP, which is a method o splitting, recombining, and seqencing

datagrams/packets across mltiple logical data links. using MLPPP allows the bonding together omltiple T1 circits to act as a single logical circit connected to the Verizon Wireless network in order

to increase bandwidth. For example, two T1 circits can be bndled to eectively provide a single

logical circit that can spply over 3 Mbps with ll-dplex capability. There is a one-time ee or each

physical circit connection.
