  3. INTRODUCTION • This contribution is prepared to help the group on how to proceed to completePARand 5C. • The following issues are addressed: • Definition of PSC • Use cases identified so far • Technical requirements for these use cases: these should be reviewed again by the group. • Procedure/steps to prepare PAR and 5C: what should be done for PAR and 5C Slide 3

  4. PROCESS IN A NUTSHELL WE ARE HERE. Slide 4

  5. WHAT SHOULD BE DONE TO PREPARE PAR AND 5C • Define PSC. • Identify use cases. • Identify conceptual system level technical requirements, not detailed technical requirements from identified use cases. • Detailed system design is not necessary: these requirements can be achieved through various technologies which can be proposed later. • Judge whether these requirements can be realized applying existing standard technologies. • Review existing technologies first. • Prepare PAR and 5C based on technical requirements identified. Slide 5

  6. DEFINITION OF PSC (1) • Ubiquitous connection to identify appropriate devices and control environment • With more centralized intelligence • Automatically with and without pre-stored information • User-oriented mobile space: user-oriented terminal [2]  provider-oriented terminal  Providers should translate their services to user I/F spec. within user mobile space. • Using various communication methods • In indoor/home environment: Short range scalable wireless network • To/from remote sources: existing networks including • WPAN, WLAN, MAN, cellular networks, and landline networks Slide 6

  7. DEFINITION OF PSC (2) • Machine-to-machine: definition from ITU-R • Machine-to-machine communication isa type of service whichexchanges data withouthuman interaction, such as remotesensor, remote bio-monitoring and personalenvironment service. This service maytransfer a small size of data traffic in a large number of sessions. • Personal environment service [5] • The electric, electronic, and mechanical machine surrounding users can be automatically configured according to the pre-defined and/or self-growing user preference. • “The living environment follows when a person moves.” Slide 7

  8. USE CASES, HOME/INDOOR ENVIRONMENT (1) • Sensors: favorite group selection • Automatic doors [1] • Automatic air conditioning [1] • Home appliances control including TV, music, and other home appliances • Automatic telephone forwarding [1] • Customized computer setting [1, 2] • auto configuration of computer • Local advertisement/information system [2] • Automatic recognition: attendance check, entrance control, automatic PC lock/unlock [1] • Private assistant: pulling conference material from user’s computer to the meeting place, personal gateway [1] • Location identification: indoor location identification, automatic destination guide from the display at the entrance or corridor, elevator control, LBS [1] Slide 8

  9. USE CASES, HOME/INDOOR ENVIRONMENT (2) • Mobile VOIP [2] • Two way graphic remote control [2] • Two way Conferencing and one way seminar[2] • Multi Lingual Interpretation System • Microphone [2] • Stereo ear set [2] • TV/game headset [2] • Smarter Phone which support Group game • Mobile video [2] • 5.1 channel audio [2] • Medical applications • Hospital environment and Doctor’s office • Customer management: It is effective from a selling area, like restaurant, store, theater, and etc. [1] Slide 9

  10. USE CASES, VEHICULAR ENVIRONMENT • Automatic air conditioning: temperature, ventilation for each passenger [1] • Automatic driving mode control: seat position, handle position, mirror angle, pedal sensitivity, maximum speed alarm [1] • Favorite music or broadcasting station selection [1] • In-vehicle navigator configuration: menu configuration, favorite geography information, geography information update and Telematics services through the mobile phone and WPAN/WLAN [1] • Hands free set [2] Slide 10

  11. USE CASES, OUTDOOR APPLICATIONS • Obtaining information from outside screens/monitors/roadside units • Stadium game broadcast • Travel and location information service: When user stands in front of the electric display guide, it shows the information about destination, geography, transportation, and shopping in user’s language [1] • Automatic street lamp control [1] • Electronic payment: Mobile communication provider could participate in E-Commerce business, and provide personalized marketing considering time and location information of users, using mobile communications network. [1] Slide 11

  12. USE CASES, PUBLIC SECTOR • Energy & CO2 saving: Light off in the place where no one shows, and optimal control for air conditioner, heater, T.V., PC, and etc [1] • Safety service: Acquisition of information about people passing by a check point, like caretaker, bus stop, lobby, and etc., using WPAN/WLAN equipped at the post, for checking pedestrians to protect from criminals, and provisioning of alarm information to them [1] • Traffic information gathering: Gathering traffic information from the mobile phones of drivers and passengers and WPAN/WLAN modules equipped at roadside [1] Slide 12

  13. USE CASES, MOBILE PHONE APPLICATIONS [3] • Mobile social network global market more than $28 billion by 2012 • More than 400 million mobile ticketing users by 2013* • Mobile location based services and location enabled apps global market over $12.7 billion by 2014** • …… • However, current cellular networks cannot accommodate every app and satisfy user’s experience well by itself. • Mobile phone applications • Indoor location-based service • Information delivery service • M-ticketing & M-payment • M-advertising & M-couponing • Mobile office • Multi-player services: mobile gaming • Multi-chatting & social networks Slide 13
