Abstract: An RTT(Round Trip Time) measuring method using a clock synchronizing signal in an asynchronous wireless indoor positioning system is provided to solve ambiguousness of TOA(Time Of Arrival) within one clock, measure accurate RTT even by using a low-priced and low spec device operated at low clock frequency, and obtain an accurate location of a person and object located within a room through the accurate RTT. A specific positioning sensor(50) receiving an RTT(Round Trip Time) positioning performing command from a coordinator transmits a clock synchronizing signal to a positioning object terminal(60)(401). The positioning object terminal synchronizes its clock with a clock of the positioning sensor by referring to the clock synchronizing signal received from the specific positioning sensor(402). After completing the performance of the clock synchronization, the positioning object terminal transmits a clock synchronization performance completion confirm response signal to the specific positioning sensor(403). In a state that the synchronization between the specific positioning sensor and the positioning object terminal is perform, an RTT measuring signal is transceived with each other(404).

Abstract: A method and an apparatus for recognizing a position using a camera are provided to grasp the current position of a corresponding user by using a camera and an electronic compass, embedded in portable terminals such as a cellular phone, a PDA, and a portable computer, in a specific space where position ID tags are arranged. An image picturing unit(221) takes an image of a position ID tag through a camera. A distance measuring unit(222) measures a distance from the position ID tag. An incident angle measuring unit(223) measures a picturing angle at a timing, when the position ID tag is pictured by the image picturing unit. An image analyzing unit(232) analyses the image from the image picturing unit, and requests the position information corresponding to the analyzed information from a position recognizing server. A position recognizing unit(233) estimates the current position by using the distance information from the position ID tag, the picturing angle information from the incident angle measuring unit, and the position information corresponding to the analyzed information from the image analyzing unit.

Abstract: A handover method in an IP-based radio network is provided to enable a terminal to receive an IP in an IP management area, and keep an IP address regardless of the movement of the terminal when there is a session performed by the terminal, thereby performing the handover of the terminal without changing the IP address of the terminal to prevent a delayed time and a data loss. A PSS(Portable Subscriber Station)(101) reports a radio access status to a RAS(Radio Access System)(102)(S401). The PSS requests a new RAS(105) to perform the handover of the terminal(S402). The new RAS determines whether to receive the terminal and transmits a handover response to a previous RAS(S403). The previous RAS sets a data path to the new RAS during handover and prevent a loss of data during the handover(S404). The previous RAS directs the PSS to perform handover(S405). The PSS performs a radio access connection with the new RAS(S406). The new RAS completes the radio access connection with the PSS(S407). The new RAS sets a radio data path to the PSS(S408). The new RAS notifies a radio access gateway(103) that the PSS is registered in itself(S409). The radio access gateway processes a registration request, releases the data path of the PSS through the previous RA, and sets the data path of the PSS through the new RAS(311,S411). Accordingly, an IP(Internet Protocol) bearer path to the PSS is completed.
Abstract translation: 提供了一种基于IP的无线网络中的切换方法，使得终端能够在IP管理区域中接收IP，并且在终端执行会话时不考虑终端的移动来保持IP地址，从而执行 终端的切换，而不改变终端的IP地址，以防止延迟时间和数据丢失。 PSS（便携式用户站）（101）向RAS（无线接入系统）（102）报告无线接入状态（S401）。 PSS请求新的RAS（105）执行终端的切换（S402）。 新的RAS确定是否接收终端并向先前的RAS发送切换响应（S403）。 先前的RAS在切换期间设置到新RAS的数据路径，并防止在切换期间丢失数据（S404）。 先前的RAS指示PSS执行切换（S405）。 PSS使用新的RAS执行无线接入连接（S406）。 新RAS完成与PSS的无线接入连接（S407）。 新的RAS设置到PSS的无线电数据路径（S408）。 新RAS向无线接入网关（103）通知PSS本身注册（S409）。 无线电接入网关处理注册请求，通过先前的RA释放PSS的数据路径，并通过新的RAS（311，S411）设置PSS的数据路径。 因此，完成了到PSS的IP（因特网协议）承载路径。
