    Abstract: PROBLEM TO BE SOLVED: To tune up an propagation model effectively with high accuracy in a simulator for predicting the electric wave propagation condition of a multi-media radio communication. SOLUTION: A measurement propagation loss is sought from measurement signal intensity data, which are sought in a running test at two or more points. A prediction propagation loss at two or more points is calculated by using the function of a propagation model. The prediction propagation loss and the measurement propagation loss are compared to seek a propagation loss deviation at the two or more points. Based on the propagation loss deviation, a virtual height for each base object is adjusted so that the propagation loss deviation is made smaller. The tilt and the interception of the prediction propagation loss curve is so adjusted that a curve formed by plotting the measurement propagation loss in a path from a base station to the two or more points and the corresponding prediction propagation loss curve may approach to each other, and the propagation loss deviation is made smaller thereby.

    解决方案:从测量信号强度数据寻求测量传播损耗,测量信号强度数据是在两个或多个点的运行测试中寻求的。 通过使用传播模型的函数来计算两点以上的预测传播损失。 比较预测传播损耗和测量传播损耗,以在两个或更多个点上寻找传播损耗偏差。 基于传播损耗偏差,调整每个基础对象的虚拟高度,使得传播损耗偏差更小。 调整预测传播损耗曲线的倾斜和截取,使得通过绘制从基站到两个或更多个点的路径中的测量传播损耗和相应的预测传播损耗曲线形成的曲线可以彼此接近, 并且由此使传播损耗偏差更小。 版权所有(C)2005,JPO&NCIPI

    Abstract: PROBLEM TO BE SOLVED: To efficiently estimate the distribution of call quality in each area in real time in a cellular communication system.
    SOLUTION: Detailed call information of each of mobile terminals is collected via a base station. Besides, with respect to a plurality of base stations, a base station information file containing at least a local number of the base station and location information is created. The call quality of each mobile terminal, local numbers of the plurality of base stations near the mobile terminal and signal propagation time information are acquired from these detailed call information and base station information file. On the basis of the local number information and location information of the plurality of base stations near the mobile terminal and the signal propagation time information, the location of the mobile terminal is found. Thus found location information of the mobile terminal and the call quality information found from the detailed call information are correspondently outputted and plotted on a map. A parameter such as call quality is filtered and plotted on the map as needed.

    Abstract: PROBLEM TO BE SOLVED: To provide a packet scheduling method capable of performing scheduling that responds to the needs of a user based on satisfaction to a packet communication speed and to provide a packet transmission processing method and a router. SOLUTION: When a terminal 11 inputs each packet 20 attached with identification data, an edge router 12 attaches satisfaction Δu obtained from the communication speed and satisfaction function of the packet 20 and subsequently outputs the packet 20 attached with the satisfaction Δu to a core router 13. The core router 13 respectively extracts the satisfaction Δu attached with each packet 20 to respectively calculate an average value for each flow where the packet 20 attached with the satisfaction Δu is inputted, defines the average value of the each flow as the weight of each flow and respectively outputs the packet 20 of each flow with the ratio of a value that is subjected to proportional division with the weight.

    Abstract: PROBLEM TO BE SOLVED: To prevent misguidance of a vehicle by appropriately locating a portion to be excluded from an initial route when travel in the initial route encounters trouble.
    SOLUTION: When a driver who drives a vehicle according to navigation guidance determines unsuitability of following the guidance and operates a switch to output a rerouting signal, a computer identifies at least one combination of road segments in an initial route as an object to be excluded, in order to correct the vehicle route. The computer then computes a new route to the destination by excluding the identified combination of road segments from the initial route without excluding individual road segments.
