Abstract: PURPOSE: A group detecting and inter-group merging method and an apparatus thereof are provided to guarantee mobility support of a node, continuous service support and QoS(Quality of Service) of a real time traffic. CONSTITUTION: The BPST(Beacon Period Start Time) of a super frame is discriminated(S801). When the BPST belongs to a different group and BPST detection of a counterpart group is possible, a beacon interval of the counterpart group is detected in a signaling slot(S803,S805,S807). If the BPST detection of the counterpart group is impossible, the counterpart group is detected using CC(collision count)(S823). If the beacon interval is detected, a beacon slot is reset/merged(S811,S813). Resource reservation is performed using BCC(beacon collision count) and DCC(data collision count) according to a detection result of the counterpart group(S825).

Abstract: A GNSS(Global Navigation Satellite System) navigation receiver and an operation method thereof are provided to shorten a TTFF(Time to First Fix) by generating valid ephemeris information by an estimation of a present time and a position. A GNSS navigation receiver includes a RF receiving part(210), a demodulating part(220), a navigation data generating part(230), a time/position estimating part(240), an ephemeris information generating part(250), a memory part(260), and a control part(270). The RF receiving part receives a GNSS navigation satellite signal from a GNSS satellite, and outputs a digital data after converting the GNSS navigation satellite signal. The demodulating part demodulates the outputted digital data, and searches a frequency uncertainty and a code delay, and demodulates an original signal from the digital data through a demodulating process. The navigation data generating part generates a navigation data by using the demodulated digital data, extracts information related to navigation information from the demodulated digital data, and generates a navigation data based on the extracted information.

Abstract: A method for correlating QoS(Quality of Service) parameters in a 3GPP-WLAN(Wireless LAN) interworking system is provided to execute one-to-one mapping with respect to 3GPP QoS parameters and WLAN QoS parameters so that efficient QoS control can be made when a 3GPP terminal having a WLAN communication function accesses a packet-based service. IP network managers(201,205), respectively installed in a WLAN UE(User Equipment)(200) and a PDG(Packet Data Gateway)(204), allocate end-to-end IP addresses for end-to-end traffic transmission. A translation/mapping function(202) in the WLAN UE(200) maps data QoS information, generated in an application layer, to QoS information generated of a 3GPP-WLAN interworking system. A translation/mapping function(206) of the PDG(204) maps QoS information of an external network to QoS information of the 3GPP-WLAN interworking system. I-WLAN BS managers(203,207) respectively request QoS information from the translation/mapping functions(202,206) and QoS parameter information from the WLAN system. The I-WLAN BS managers(203,207) map traffic QoS information to QoS parameter information of the 3GPP-WLAN interworking system and manage the present communication resource states and the tunneling between the WLAN UE(200) and the PDG(204).

Abstract: A position-based routing method by using a cell in a wireless sensor network is provided to minimize the energy and to determine a path until a destination node easily by reducing the periodical communication for the position information confirmation. In a next-hop position calculation process, the virtual ONI(Optimal Next-hop Information) among the paths until the destination node is calculated. In a communication area division process(302), the communication area is divided into fixed cell sizes by using the calculated virtual ONI position. In a packet broadcasting process(303), a packet including the virtual ONI position and the cell sizes is broadcasted to the surrounding node in the communication area. In a next-hop node decision process(305), the firstly transmitted surrounding node is determined as the next-hop node after receiving a response message in regard to the broadcasted packet from the surrounding node. In the next-hop position calculation process, the position joined by the virtual segment for connecting the distance until the destination node and a virtual circle corresponding to one's own communication area is calculated and the calculating result is determined as the next hop position.
