Agenda








• Global System for Mobile communication (GSM) is a European Telecommunication Standard Institute (ETSI) specification

General Packet Radio Service (GPRS) is a subset of the GSM specifications

• A GPRS capable GSM network generally consists of two portions:

Voice which is a circuit switched network

Data-overlay which is a packet switched network

GSM/GPRS Network Architecture Overview

Links: http://www.3gpp.org/ ; http://www.gsmworld.com/


General Packet Radio Service (GPRS)—Fundamentals

• Available today over GSM networks

• Based on the transport/routing of packetized data

• Capacity based on amount of data transmitted rather than connection time

• Works with public data networks using IP

• Supports “bursty” applications such as e-mail, broadcast services, and Web browsing

MPLS VPN Implementation

Benefits• Security—MPLS routing paths and network visibility is VPN specific • Flexibility—operators may use private addressing without Network Address Translation• Simplified Network Administration—no need to configure a PVC mesh• Scalability—MPLS solutions scale to very large networks with thousands of devices as well

as extending across Inter -PLMN network segments • Extensive Platform Support—Cisco 2600, 3600, 4000, 7200/7500, 12000, Catalyst 6500



Security—Solution

• Interconnection security issues—Access Control Lists on gateway routers to the InternetEncrypted traffic from operator to corporate sitesMPLS VPN traffic over GRX Provider

• Firewall placement issues—Two levels of firewall security—

Web servers, cache engines, mail servers—loose DMZ protection Content servers and database engines—“locked down” protection

• IDS devices + PIX firewalls to detect and prevent Denial of Service attacks

• Subscriber verification and data encryption/key managementDevice and subscriber access/verification—AAA functionsIKE support with shared Certificate Authority—Encryption functions

Cisco PDSN Solution


Packet Data Services

• Internet access services

Through home ISP

Directly from the cdma2000 Service Provider

• Intranet access services

An authorized user can access its private network

A private network can use the non-registered IP address pool for its mobile users

Overlapping non-registered IP address pools from different private networks can be supported

Links: http://www.cisco.com/warp/public/779/servpro/solutions/wireless_mobile/pdsn.html



Standards-Compliant

• 3GPP2 TSG-P standard, Wireless IP NetworkStandard (P.S0001 or TIA/EIA/IS-835)

Defines the overall structure of a cdma2000 network, including enhanced mobile IP, carrier-class accounting, compression, security and authentication

• 3GPP2 TSG-A, Inter-Operability Specification (IOS) for cdma2000 Access Network Interfaces, (A.S0001 or TIA/EIA/IS-2001)

Focuses on the radio side and the interfaces between radio components and the PDSN

Links: http://www.3gpp2.org/


PDSN Key Features

• Intelligent PDSN selection with PDSN clusters

Avoids disruptive handoffs and balances call load across PDSNs

• Proxy mobile IP

Allows mobile stations that do not support mobile IP to maintain session connectivity as they move

• Multiple IP flows per mobile station

• Rich set of QoS features

• Extensive security/VPN features

Key IP Elements for Wireless Operator Data Networks

• IP Address Administration

• Filtering and Quality of Service

• Traffic Engineering

• Service Level Agreements

Sessions: IPS-130 (Intro to QoS) ; RST-231 (Deploying MPLS for Traffic Engineering)



Problem—IP Administration Overhead

• Issues include—Address administration that facilitates route summarization and filtering/QoS assignment

Dynamic IP address range assignments

Use of private/public addresses for network devices and subscribers

• Ongoing administration aided by triggered database updates

• IPv6 and IPv4 interoperation?


Why a Larger Address Space Is Needed

• Overall Internet traffic is still growing at 400%/year world-wide

~320 million users in 2000, ~550 million by 2005

• New Internet appliances for home users will be always-on

• 405 million mobile phone users in 2000, over 1 billion by 2005

UMTS Release 5 is Internet Multimedia, 1/3 of 1B should get connected

• Emerging population/geopolitical and address space

China, India, Japan, Korea needs global IP addresses

How to move to e-Economy without Global Internet access?

• ~1 billion cars in 2010, 15% should get GPS and Yellow Page services

Summary

• An epic time of changeVoice is still there, but data is the differentiator

• GSM and CDMA data overlaysMobility, sessions, gateway functionality

Roaming, security, and MPLS

• Building an IP core is not trivial

IP brings many benefits

Network should be designed carefully
