Background

Goal of Wireless (Mobile) Internet Service

• For users
• Enjoyed various contents independently for
  wireless carriers and handset
• For wireless carriers
• Availability of broader range of compelling
  contents for delivery
• More downloads through within service and roaming
• For handset vendors
• Reduction in engineering cost and time
• If outsourcing, availability of broader choices
  of implementers
• For content/application developers
• More focus and resource allocation for designing
  the substance of contents
• Wider distribution channel

8
WIPI Wireless Internet Platform for
Interoperability

• Application execution environment specification
  for the mass market handsets
• Developed under the guidance of KWISF (Korea
  Wireless Internet Standardization Forum) as Forum
  Standard
• Made official standard in Korea through TTA
  (Telecommunication Technology Association)
• Specification embodies the knowledge of the
  carriers, handset vendors and application
  developers gained through deploying various
  platform technologies

9
WIPI Design Philosophy

• Balance of strictness for compatibility across
  implementations and flexibility for
  differentiation
• Security feature to meet MExE requirements
• Co-existence with other technologies such as WAP
  and MIDP
• Independent of underlying OS and air interface
• Embrace broader community of application
  developers

10
Functional Overview Mandatory Feature

• Support for multiple programming languages C/C
  and Java
• Download and execution of all programs as binary
  code
• Concurrent execution of multiple programs in
  independent memory spaces, with IPC capability
• Fine grained platform security
• Multiple level API access and Multiple level
  data access control
• Memory management
• Automatic and manual garbage collection with
  memory compaction
• Automatic memory de-allocation up on program exit
  and Shared memory management
• Application management
• Support for internationalization Unicode, locale
• API and component management
• Download and dynamically link additional APIs and
  components
• The downloaded items become part of WIPI
  implementation deployed
• Update downloaded APIs and components
• Over the air platform update
• Update application manager capability and/or UI

Area of Standardization
Renders all the above layers in the stack
hardware independent, thus the platform operates
on common hardware abstraction layer.
Set of APIs exposed to application programmers.
These APIs support both programs written in C and
JavaTM programming language.

Security Model Platform Security

• Multiple access privilege levels of resources for
  applications
• System Level - allow access to all
• CP (Content Provider) Level restrict access to
  critical areas
• Public Level restrict access to critical areas,
  user information, etc.
• API access control
• Data (file) access control
• Private directory restrict access to all other
  applications
• Application shared directory shared by
  applications with access privileges
• System shared directory shared by all with
  access privileges

Current Activity for WIPI 2.0

• Now WIPI currently update and upgrade by the
  standardization bodies, of KWISF (research
  institutes, venders, telecommunications,
  implementers solution providers, contents
  providers) with WIPI2.0 TFT.
• Harmonized Platform (WIPI 1.x MIDP 2.0)
• Code Optimization
• Enforced function of Multi-Tasking and
  Multi-Window
• Add Rich API sets on WIPI
• Camera API
• Multimedia API and MMSs API
• Hardware Adaptation Layer (HAL) API for enhanced
  system
• Security API as Banking services

Future Mission

• The specification is freely open to all
  interested World Parties and spreads as
  international standardization
• OMA-3GPP/2, JCP etc
• Collaborate on International standardization with
  SUNs and etc.
• Platform and Application certification for
  Interoperability (IOT)
• Signing of application descriptors and
  executables
• Now TTA certifies applications in Korea
• Certification of Platform should be done for
  interoperability
• Harmonize of SUNs TCK and PCT
• The Policy of WIPI Next Generation
• Expansion of Rich API set for multimedia
  contents and applications
• Development of platform for Smart phone as
  embedded software
