Abstract: [In the future, most of users want to maintain their environment mobility within a moving personal space. So, Personal Environment Service(PES) based on WPAN technology would be leading & killer application of Ubiquitous services in the future. We can figure out 5G mobile communication is only the connections of the PES spaces. ]

U-공간을 연결해 주는 저전력 근거리 무선의 표준이 완성되면
4G는 U-공간과 U-공간을 연결하는 서비스일 뿐이다
이 때 U-공간을 연결하는 다양한 통신 수단은 단순한 선택 대상일 뿐이므로
U-공간내의 표준이 이루어지면 4G의 표준은 U-공간과 U-공간을 연결하는 방식만
약속하면 되므로 U-공간의 표준이 이루어지면 4G의 표준이 이루어진 것이나 다를 것이 없다.
앞 슬라이드에서 정의된 U-interface 의 표준을 외부와 연결하기 위해서는 mail box를 정의해야 하고
각 U-interface 의 mail box 와 mail box를 연결하는 것이 4G network의 구조가 될 것이다.
이 때 4G Network의 기본 요구조건은 가장 공간의 멀티미디어
ㅡ multicast가 되어   
     □ Interface C : (서비스 정의 mail box 표준화)
         ◦ 기존의 기간전송망 사용 (회선 교환, 패킷 교환, 케이블, 위성 채널 등)
         ◦ 서비스 정의에 필요한 parameter 와 이를 주고 받는 protocol 만 정의
       □ Interface C
         ◦ 기존 통신 방식을 그대로 사용하고 서비스 정의용 Parameter 만 표준화 
         ◦ 개인적인 정보보호를 위해 강하된 통신보호 방법이 강구되어야만 함
         ◦ 복합 단말기와 개인서버와의 동일한 DB 유지 기술이 필요

18. Conclusions What is the PES ?
Facilities surrounding users can be automatically configured to user preference.
The user interface environment within user space follows when a person moves.
It provides broadcast, multicast, communication & sensor convergence service.
User terminal can select a service among services broadcast by providers.
It could be leading & killer application of Ubiquitous services.
What kind of WPAN solution is suitable for PES ?
Dual support for both low power sensor and high speed multimedia.
Container concept to reject mutual interference and converge various services.
Abundant channel capacity based on avoidance of mutual interference.
Hierarchical sync & frame structure for scalable & self organizing system.
PES Protocol can be used for 5G mobile communication, too.
PES personal space & mobile femto-cell have almost the same structure.
In the future, the cell size of 5G will become femto-cell because of capacity.
5G network merely a connection of user oriented mobile spaces.
White space devise requirements would be satisfied with PES protocol.
