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.

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.

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

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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

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.

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.
