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

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 [email protected] for
access authentication
Accounting traffic: for data settlement, and end user billing

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 3rd
party network

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
