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 RoamingPhilip Hur

15
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_at_realm.com for access authentication
• Accounting traffic for data settlement, and end
  user billing

16
Packet Data Roaming Environment (continued)

• Domestic partners - SIP, MIP, 1X, EVDO via direct
  facility
• International partners 1x SIP via direct
  facility, 1x EVDO MIP via CRX provider

17
TELUS Mobility Roaming Services Overview

  worldwide with Mobile IP preferred.
• Non-Home based services
• Internet access including browsing, email and VPN
  etc.

  servers directly via Internet or 3rd party
  network
• Home based services (all services using Mobile IP
  technology)

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 Partners RNC shall honor the Radius
  attribute Callback-Id
• returned from TELUS home AAA during AN-AAA
  authentication phase
