摘要： The managed object instance is used as access control unit, then access denial and permission are quickly decided. After a pre-process to the naming tree which is an object of access control, MOI included within every scope which can be designated by the management operation is obtained. At every issue of the management operation, access denial and permission are decided by using the data obtained in the pre-process. When the configuration of the naming tree is changed, the data are easily and rapidly revised, then the access control is adaptive to the dynamic change of the naming tree.

摘要： The present invention provides a system for wireless data communications that allows, in P-MP wireless data communications, equally giving communications opportunities to mobile stations that directly communicate with a wireless base station and mobile stations that indirectly communicate therewith via a relay station and a communications method thereof. In comparison with the OFDM frame configuration prescribed in IEEE802.16, an OFDM frame configuration is characterized in that, in an uplink subframe, a ranging period and BW (bandwidth) request periods for a relay station are provided, and furthermore, a remaining message number notice period for which each relay station notifies the wireless base station of the number of remaining messages is provided. These periods are not of a contention base but bandwidths dedicated to the relay station.
摘要翻译：本发明提供了一种用于无线数据通信的系统，其允许在P-MP无线数据通信中向与无线基站直接通信的移动站以及经由中继站和通信间接通信的移动站同等地给予通信机会方法。与IEEE802.16中规定的OFDM帧配置相比，OFDM帧配置的特征在于，在上行链路子帧中，提供了中继站的测距周期和BW（带宽）请求周期，此外，还提供了剩余消息提供每个中继站向无线基站通知剩余消息数量的通知周期。这些时段不是竞争基地，而是专用于中继站的带宽。

摘要： A polling period controlling apparatus capable of polling with a period traceable temporal variations of management information values of a managed unit is provided with a polling period calculator 5 which decomposes a sequence of management information values, stored in the sequence memory 4, into the sum of sinusoids with different frequencies to find the maximum frequency and determines the polling period from an inverse of two times the largest frequency. A central controller 2 then compares between the required bandwidth specified by the polling period and a network management bandwidth and, when the former is smaller than the latter, obtains the management information value from the managed unit 11 using the polling period. When the former is greater, the central controller 2 obtains the management information value using the polling period determined from the network management bandwidth. The management information value obtained is saved in the sequence memory 4 while the oldest group of management data is eliminated.

摘要： If an error range is specified with regard to the cost beforehand, a route satisfying all of a plurality of QoS conditions at a low cost and having a cost in the error range is selected as an optimum route. Such a route selection method is provided. At step S1, a plurality of QoS conditions to be satisfied are set. At step S2, an approximation error &egr; is input. At step S3, a range of a cost for searching for an optimum route is tentatively set. At step S4, an optimum solution cost approximation procedure is executed. At step S5, it is determined whether the cost searching range has been sufficiently narrowed. If the narrowed cost searching range is still too wide, then the processing returns to the step S4 and the optimum solution cost approximation procedure is repeated. If the cost searching range has already been narrowed, an optimum solution deriving procedure is executed at step S6.
