Cellular Data Market Forecast (1/3)

• US
• The total number of cellular data users in the US
  will increase from 1.9 million in 1998 to 28
  million in 2003.

• The proportion of all cellular users using data
  services (messaging, information services, or
  remote access applications) will increase from
  2.7 to 21 over the period.

• By 2003, US cellular data revenues are expected
  to reach US 2.6 billion.

TDMA Data Services - Operator Value

• Capture wireless data market share

• Build operators brand image (new services,
  Internet Access, )

• Limit churn

• Build competence in data services deployment

• Information collected during commercial life of
  2nd generation data solutions will be an
  invaluable source for deploying 3rd generation
  data solution (traffic, capacity, pricing models,
  marketing, )

TDMA Digital Data and Fax Service

• provides a circuit switched data access over the
  Digital Traffic Channel (DTC) air interface

• supports a maximum uncompressed user data rate of
  9.6kbps

• supports data compression over the air interface
  (V.42bis)

• interworks with all popular standard landline
  modems and fax protocols (e.g. Data V.34,
  V.32bis, Fax V.29, V.27ter, )

• provides data privacy over the air interface
  (encryption)

• supports automatic roaming

• supports seamless handoff

11
System Requirements for Digital Data and Fax

• Mobile supporting IS-130, IS-135 and IS-136-A
  required (Ericsson T18d)

• Digital base station required (884, 882D, 882DM)

• TRAB2 (or "higher) located in the MSC

• DTIs required in each MSC providing the Digital
  Data and Fax service

• IS-737 Inter-node (MSC-HLR) signaling required
  (changes to IS-41-C to support Circuit Switched
  Data and G3Fax)

• Data encryption requires that the Authentication
  Center shares the SSD with the MSCs

• For mobile terminating calls from PSTN, Ericsson
  supports Two Stage Dialing in the MSC.

Data Transmission Interworking (DTI) - Overview
(3/5)

• RPBU Regional Processor Bus Unit.
• Connects the parallel RP bus to the DTI for RP
  bus redundancy
• PRO20 This is the Regional Processor Device
  (RPD)
• Stores the code for the TR PBA
• Performs surveillance of the HW
• Gateway for signaling between the Central
  Processor (CP) and Device Processors (DP) of the
  TR PBA

15
Data Transmission Interworking (DTI) - Overview
(4/5)

• GSIB Group Switch Inter Bus.
• Provide two DL-2 connections to the Group Switch
  (GS)
• Interface between PRO20 and TR PBAs
• TR PBA Traffic Printed Board Assembly
• Contains the Device Processors (DPs) which
  perform the interworking functions.

16
Data Transmission Interworking (DTI) - Overview
(5/5)

• A fully equipped DTI magazine has 8 TR boards
• Each TR board can handle 4 calls
• For full redundancy, 2 DTI magazine are needed
• The number of DTI magazines is only limited by
  the number of available RP bus addresses (max
  1024)

TDMA Direct Access Service (1/3)
23
TDMA Direct Access Service (2/3)

• Provide internet access to TDMA-136 subscribers

• Offers faster call set-up and response times
  compared to calls placed through the PSTN

• Opens up new business opportunities for TDMA
  operators
• to offer Internet and Intranet access services
• to become an Internet Service Provider

• Operators can achieve savings on interconnection
  fees by transporting data traffic on data
  networks (instead of using PSTN and PLMN)

• TCP/IP access offered using one network (vs PSTN
  and PLMN)

The wireless data call is initiated...
the dialed digits are received in the MSC ...
digits are analyzed and the call is setup to
the access server
the access server converts the circuit
switched connection to packet switched ...

Internet/Intranet information is accessed.
27
Direct Access System Requirements

• Access servers required in the network

• The Digital Data and Fax MSC software needs to be
  active

• The Direct Access MSC software needs to be active

• ISUP signaling required in the network
