PROBLEM TO BE SOLVED: To enable a mobile virtual network operator (MVNO) and a person who provides service by utilizing wireless communication service of the MVNO to freely and inexpensively provide the service. SOLUTION: A base station 1 includes: application parts 4, 5, 6; a selection part 7; and a controlling part 8. The application parts 4, 5, 6 have applications corresponding to the service of the person who provides the service by utilizing the wireless communication service of the MVNO. The selection part 7 receives a connection request to the service of the person who provides the service by utilizing the wireless communication service of the MVNO from a terminal 2 of a person who utilizes the service of the person who provides the service by utilizing the wireless communication service of the MVNO. The selection part 7 selects an application part corresponding to the connection request among the registered application parts 4, 5, 6. The control part 8 controls communication between the application part selected by the selection part 7 and a server 3 of the MVNO. COPYRIGHT: (C)2011,JPO&INPIT
Abstract:
PURPOSE:To prevent an optical disk cartridge from being damaged, by positioning successively a picker to a cell when it is instructed to push in the disk cartridge, and moving the picker to a prescribed position detected by a detecting means. CONSTITUTION:When it is instructed to execute a cartridge collision preventive program, a control means moves an accessor 3 in the directions as indicated with arrows A-B, and subsequently, moves a picker 4 in the directions as indicated with arrows C-D, and positions the picker 4 at a position of a cell of a housing shelf 10. Subsequently, the picker 4 is moved in the direction as indicated with an arrow F. In this case, the control means monitors an output of a detecting means, and stops a motor when it is detected that the picker 4 is advanced to a prescribed position. Next, when the picker 4 is moved in the direction as indicated with an arrow E and returned to its original position, said operation is repeated with respect to the next cell. In such a way, a disk cartridge 11 can be pushed in by a prescribed quantity against the housing shelf 10, and damage of the cartridge 11 can be prevented.

PROBLEM TO BE SOLVED: To enhance service quality.SOLUTION: A control section in a wireless base station determines the priority of a calling signal being transmitted to a mobile station. A baseband section transmits a first calling signal of first priority to the mobile station. A second calling signal of second priority lower than the first priority is stored in a queue and subjected to transmission processing. When the storage capacity of a queue is exceeded and the second calling signal is discarded, the fact that the second calling signal has been discarded is notified to the mobile station. When the calling signal of its station is discarded, the mobile station receives a notification that the calling signal has been discarded, and when it is recognized, the mobile station performs inquiry response to the wireless base station.
Abstract:
PROBLEM TO BE SOLVED: To freely form a restriction zone in a desired area in a service area without any specific operation in a call originating-incoming control system that forms a controlled zone to restrict communication service in a desired area among radio zones of a mobile communication system, in a control base station equipment that forms the controlled zone and in the mobile communication system that sets a channel in interlocking with the restriction base station equipment. SOLUTION: This method employs a large number of radio base stations 11-1-11-M to restrict call transmission/reception of a mobile equipment 12 in a mobile communication system where communication is made between the mobile equipment 12 and an opposite terminal via a radio base station in response to the location of the mobile equipment 12. In this case, a control base station 13 is provided, which makes radio communication between any of the radio base stations 11-1-11-M and the mobile equipment 12. The control base station 13 sets a controlled space to restrict call transmission-reception of the mobile equipment 12 so as to restrict the call transmission from the mobile equipment and the call reception by the mobile equipment 12 resident in the controlled space.

PROBLEM TO BE SOLVED: To provide a system which can obtain position information on another vehicle with a minimum frequency of communication irrelevantly to the number of vehicles forming a group. SOLUTION: Each navigation device 101 is equipped with an information transmitting means 111, which sends an information registration request including identification information and vehicle information on this vehicle, a report request means 112 which sends out an information report request including the identification information, a display means 113 which displays inputted vehicle information on respective vehicles, and an information receiving means 114 which extracts vehicle information from a response signal and uses it for the processing of the display means 113. A communication management station 102 is equipped with a vehicle information storage means 115 which stores vehicle information corresponding to identification information of respective vehicles, a registration means 116 which registers vehicle information included in the information registration request in the vehicle information storage means 115, and a retrieval means 117 which retrieves corresponding vehicle information from the vehicle information storage means 115 at the information report request and sends out an answer signal including the vehicle information to the request source.
Abstract:
PURPOSE:To extend the number of times fro retry operations and to efficiently execute a retry processing by measuring practical time for retry, comparing it with the total sum of time for retry and continuing the retry processing when the practical time for retry is shorter. CONSTITUTION:When operational error is generated, a medium conveying mechanism control part 4 lets a medium conveying mechanism part controller 3 execute a retry 1 processing. Next, it is discriminated whether the retry 1 processing is made successful or not, and when it is successful, a medium conveying mechanism control part 4 announces the success of retry to a host device 10. When the retry 1 processing is failed, practical retry time T1 for the retry 1 processing is calculated, and practical retry time T is calculated. Next, the practical retry time T is compared with the total sum of retry time SIGMATn (ten minutes, for example,) to be Device I/O Time Out and in the case of SIGMATn =T, a retry 2 processing is executed. Then, it is discriminated whether the retry 2 processing is successful or not and when it is successful, the next step is started. Practical retry time T2 for the retry 2 processing is calculated, and the practical retry time T adding the T2 is calculated. Next, the SIGMATn is compared with the T and in the case of SIGMATn>=T, a retry 3 processing is executed. Afterwards, the retry operation is continued as long as possible. Thus, the number of times for retry operations can be extended.
