摘要： An IP tunnel is constructed between routers connected with the INTERNET. A bandwidth of the IP tunnel is assured by setting up a reservation resource protocol (RSVP) on the IP tunnel. Further as a traffic control of the routers and on the IP tunnel, a frequency for sending packets, which are processed by an input processor and an output processor inside of the router, is allotted based on a ratio of the reserved bandwidth in each IP tunnel, then an algorithm for controlling the traffic is simplified. Furthermore each of the routers on the IP tunnel has a function for scheduling a reservation and manages a time period at which the virtual private network (VPN) of a type of the reservation resource protocol (RSVP) will be used, then it is possible to reserve the assurance of the bandwidth on the designated date and time in the future.

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： A cell disassemble circuit in a cell receiver system detects the number of lost cells from information for detecting cell loss included in received cells, and separates a payload from a header in each of the received cells. The number of lost cells indicates the number of cells lost on a transmission path from the transmission side to the cell receiver system. A buffer stores the number of detected lost cells and data inserted in the payloads. A phase locked loop recovers a source clock corresponding to the rate of fixed rate information based on a use level of the buffer. A counter circuit generates a clock for reading data from the first buffer from the recovered source clock. Also, the counter circuit stops outputting the read clock to the buffer for a time period corresponding to the number of lost cells.

摘要： A service-system low-speed interface unit and a protection-system low-speed interface unit are each provided with an optical transmitting/receiving module adapted to communicate signals with a main terminal. The protection-system low-speed interface unit is provided with another optical transmitting/receiving module for communicating signals with a part-time terminal. This module is selectable by a changeover switch in the protection-system low-speed interface unit. The connected configuration in the service system and the protection system is changed to allow the main terminal to make communications using either the service system or the protection system. If the main terminal makes normal communications using the service system, the part-time terminal will be allowed to make communications using the protection system by selecting the optical transmitting/receiving module for the part-time terminal with the changeover switch in the protection-system low-speed interface unit.

摘要： A reiterative learning procedure with training and test processes for a binary supervised neural network includes at least an error signal generator for weighting factor updating in the training process, which generates an error signal that is perturbed in polarity and amplitude in the difference derived by subtracting an output unit signal from corresponding binary teacher signal and then generates the difference as an error signal after a maximum absolute value of differences among erroneous binary output signals has become smaller than a threshold once. A training signal memory stores a set of training signals and adds test signals providing erroneous binary output signals that are transferred from a test signal memory in the test process to the set of training input signals as incremental training input signals. An affordable signal memory stores input signals with sufficiently large margins providing correct binary output signals that are transferred from the training signal memory in the training process and the test signal memory in the test process. The reiterative learning procedure, with minimum necessary training and test input signals and control of the error perturbation in the training process, can provide a binary space to obtain a desired binary output, and also realizes an extremely high generalization ability.

摘要： A mobile communication system has a cell structure constituted by integrating macro cells and micro cells, and at least one mobile station. The cell structure is made to cover a service area by a plurality of the micro cells each having a predetermined size and to cover the same service area by the single macro cell having a larger size than the size of the micro cell. Each of the micro cells includes a micro cell base station for transmitting at least radio control channel at a predetermined frequency and slot. The mobile station includes a measuring unit for repeatedly measuring received level of the radio control channels from the micro cell base stations, an estimation unit for estimating its moving speed in accordance with changing rate of the measured level, and a determining unit for determining, in accordance with the estimated moving speed, that control of a radio link between the mobile station and the base station is executed by a micro cell unit or by a macro cell unit. In one aspect, the macro cells may be virtual macro cells each of which is a virtually treated area covered by a plurality of the micro cells. If the repeatedly arranged virtual macro cells are formed as a layer and also multi-layered so that the service area is closely covered, the spectrum efficiency can be more increased.

摘要： A variable length code system which is instantaneously decodable in both forward direction and backward direction is generated either in asymmetrical form or symmetrical form. The code thus generated has high transmission efficiency, and capable of backward reconstruction of video signals even when some bits are lost during transmission. The symbols to be encoded are prepared (1) with occurrence probability, and they are provisionally encoded to a non-reversible variable length code (2). Then, the provisional code is transformed to an asymmetrical reversible code (4) through equivalent transform process (9), reverse symbol tree process (10), and bit supplement process (12) when suffix condition is not satisfied. The provisional code is also transformed to a symmetrical reversible code (3) by assigning a symmetrical code word to each symbol on a symbol tree (FIG. 5). At least one of symmetrical code or a asymmetrical code is selected (5), and is provided as a final resultant code.
