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

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
