LBS Network Architecture Location Studio nodes are exposed to the

internet for Secure MLP requests from application providers

Location Studio is the front end for the MPC, responsible for billing, provisioning and authentication

Location Manager nodes and PDE utilize SS7 links to the STP for Control Plane fixes

WARN feeds use redundant frame relay circuits

MPC nodes are in active/active HA configuration

Packet Data Roaming

Philip Hur

TELUS Packet Data Roaming Environment

TELUS currently supports international packet data roaming via CDMA Roaming eXchange (CRX) transport network

The data traffic carried over the CRX network between TELUS and the roaming partners’ networks can be categorized as the following:

IP data transport: for Simple IP (no L2TP) and Mobile IP traffic accessing home-bound services

Authentication traffic: to grant access to outbound roaming users at visited networks to either local Internet or home services using user@realm.com for access authentication

Accounting traffic: for data settlement, and end user billing

TELUS Mobility Roaming Services Overview

TELUS will expand packet data roaming environment worldwide with Mobile IP preferred.

Non-Home based services: Internet access including browsing, email and VPN etc. Application to ASP (Application Service Provider) servers directly via Internet or 3 rd

party network Home based services (all services using Mobile IP technology):

Microbrowsing (WAP 1&2)

– Wireless Web, Instant Messaging, Web Games, and E-mail MMS

– Picture, Audio, Video Messaging Downloads

– Games, Images, Ringtones PTT (Push To Talk) 1xRTT & 1xEv-DO Managed Data Service – MIP solution RIM Blackberry

TELUS Packet Data Roaming Preferences

DNS TELUS strongly recommends roaming partner to NAT the serving DNS address

to home DNS address for MIP roaming user on foreign network, before the HA/AAA/device in the market can support dynamic DNS assignment in accordance with IS-835D

Mobile IP Mandatory reverse tunneling Support for registration revocation IP-in-IP tunneling encapsulation; No IPSec/IKE

EVDO A12 terminal authentication Roaming Partner’s RNC shall honor the Radius attribute Callback-Id

returned from TELUS home AAA during AN-AAA authentication phase
