New Fixed Network operators are launching

Bundling services and price package.

Example: web TV service + TFN ADSL

discount coupon = NT$800

The existing broadband ISP / content

providers are trying to be aligned with on-line games


11/38


broadband access ? (Cont) Always-on connectivity will be more and

more popular. (experiences in UK)

Managed services with networkmanagement, web hosting, and highreliability are favored by corporate users.(the IDC model)

Outsourcing is a business sector.(experiences from US: EDA, IBM)


12/38

What is next in Taiwan ?

The Voice over IP services ISR(International Simple Re-sale ) and VoIP services will

be deregulated at July 2001.

Special Type-2 operator licenses are required. Draft of regulatory rules are being posted at DGT web site.

(For soliciting public opinion)

Expected to attract more than 100 new ISR in Taiwan.

(3 digits of access codes reserved: 18xyz) VoIP operators will be able to lease circuits (domestic and

international) directly from land-based or submarine cable

operators. Lower cost for bandwidth is expected.


13/38

What is next in Taiwan ?

The Voice over IP services A price war is expected.

The whole sale price will soon drop to the international

level. ( ? cents/min. ) In the short term, will be a major business for IDC, and

ISPs ISP, or submarine cable operators.

In the long term, those with sales channels, QoS assurance,

and additional value-added services will success. VoIP may soon become a standard option on ADSL or

cable modem.

18/38

Emerging Service in Future

Mobile Systems Information Services:

Short Message Service

Circuit Mode Data Service: charged by time Packet Mode Data Service: charged by packets, or

transactions.

Example:

WAP is Circuit mode Data Services WAP over GPRS is packet mode data services

WAP over 3G can be packet mode data services orcircuit mode data service


19/38

Emerging Service in Future

Mobile Systems Location Dependent Information Services

Allow user to download (or semi-automatically down

load) information, according to the location of themobile user.

Allow the operator to analyze the user behavior before

providing additional information

Additional Location Measurement Unit, Location

Computation Server or Behavior Data Mining Server

required

Available in 2G- 3G era.


20/38

IP and Data Service in 3G No vendor can develop the required core network from

scratch.

The IP transport nodes in 3Gs core network will be basedon todays IP technology, especially the IP core of GPRS

Although the IP transport technology in 3G core network

is very similar to data network, the charging/billing

solution and QoS control is very different.

The core network may implement IETF QoS standard

(DiffServ. etc), in addition to IMT-2000.


21/38

IP and Data Services in 3G Open access of service platform(HLR, AAA

severs), in the form of API (OSA), in 3G network

is essential to for content provider/ISP to developa complete service scenario.

Scenarios in GPRS can be used as examples.

However, 3Gs IP core are either router or IP

switching platform, plus mobile IP functions,

which allow possibility for integration.


22/38

Key Features of future IP

services Must Support Mobile IP

Must Support Dynamic IP address

Must Support IP VPN Must Support Voice over IP

With IP security requirement: firewall betweenISP and 3G core network

IPv6 is essential and mandated in the long term Auto-configuration

Permanent Address for every mobile station,Information appliance.


23/38

About WAP The Wireless Application Protocol (WAP):

designed to improve the performance of TCP/IP under

wireless environment can operate over circuit mode, or packet mode,

can operate over GSM circuit mode, GPRS, or 3G.

Different modes of WAP have compatibility problem;

so are their handset. Although WAP may still operate over 3G, the

service is unlikely be call WAP directly.


24/38

What is 3G applications ? Applications developed over standard 3G

wireless services and systems? or

Applications developed over 3G based

systems and terminals.

We do not know what will be the killer applications

..Be flexible and agile, keep resource ready to build

what ever is hot.

- John Zehlis, Chairman &CEO AT&T Wireless


25/38

Experiences in I-mode Email, Information Services and Leisure Services are

equally important.

The content provider can develop the same content with asingle format and provide it to both wire and wireless users.

The payment agreement between operator and content

providers. (9% charged by NTT DoCoMo)

26/38

Potential Killer Applications

in Future Wireless Always-on Applications : monitoring and security

Mobile e-Commerce (on-line shopping, e-coupon,

yellow page, etc.) media applications ( news broadcasting,

entertainment video, video phone, tele-conferencing.)

Intelligent Transport System (location services,fleet management, Emergence services)

Machine-to-machine communications: securitysystem, vending machine, energy reservation, etc.


27/38

Location Based Applications and

Services

Two major modes of Location Based Services(LBS):Handset based vs. Base-station based

The handset(mobile station) approach:

require GPS function for each handset. The location isreported back to network. The limitation is the unavailability of GPS signal when user is in

indoor. Not every handset is equipped with GPS.

FCC E911 requires 125meter by 10/1/2000. But GPS approach canreach 50 meter or better.


28/38

Location Based Applications and

Services The base station approach: require BS to be synchronized

(via GPS) and then the difference of Time-of-Arrival fromdifferent base station is used for location positioning.

Local Measure Unit (LMU) may be required at BS. OTD(Observed Time Differences) approach is similar but

less Location Measurement Units

The multi-path problem or optional repeater/leakage canlead to serious error.

There are many solutions to support 2G,2.5G or 3G. The accuracy of Location Based Services is expecting to

improve.


29/38

Application Scenario of Location

Services 119/110 Emergence Call Scenario:

A user dials 119/110 for help and he/her

location is directly reported to the closest 119station.

Smart Car Emergency Broadcast Scenario:

The smart car automatically report an accident

when the air bag explodes. The location is automatically broadcast to 119,

the insurance company, the nearby hospital, etc.


30/38

Application Scenario of Location

Services Health care applications:

The handset is equipped/connected with health care or

monitoring devices and GPS.

In an emergence situation, the measurement data and

location information are both reported to the medical

team.

Kid Watching applications: The handset is with GPS and is owned by parent. The

location is reported if the father or mother requests.


31/38

Handset/Communicator based

applications Future wireless terminal can located within many

intelligent information devices:

Notebook, PDA Digital Camera,

Office Appliance: Copy machine, Vending machine,

Home Information Appliance

Health care devices

Security Alarm System, Energy metering and control

Set Top Box

The display of wireless terminals can be withvarious forms.


32/38

Challenges from 4G

orBeyond 3G 4G is expected to solve unsolved problem in 3G:

Speed, air interfaces, etc.

4G is expected to be with much large bandwidth

NTT Docomo is targeting at 10Mbps-20Mbpsfor B-WLL in 4G.

4G is expected to introduce new technologies suchas: Software radio (for all kinds of air interfaces)

All IP and Optical network (in core network)

Convergence of Broadcasting

and Communications Standards for DVT soon will be determined by

DGT and MOTC.

Although North American standard ATSC isunder trial, European standard DVB-T isbecoming more popular among TV broadcaststations. Better support for mobility

Better Spectrum Utilization

Either support interactive mode and conditionalaccess


37/38

Conditional Access and

Return Path in Digital TV The return channel of Interactive TV can be

telephone modem

uplink in HFC GSM or other mobile service

satellite uplink channel

other broadband access

When conditional access (CA) is required, the settop box will need additional CA module.

In Taiwan, multiple CA solutions may exist,unless enforced by government.


38/38

Conclusions Fixed/mobile/Internet/Media sectors will

continue to merge.

The collaboration between operators,

handset/IA/ PC vendors, and

application/content provider is a must.
