| 20080242303 | RADIO COMMUNICATION METHOD, RADIO MOBILE DEVICE AND RADIO BASE STATION ACCOMMODATION APPARATUS - In a radio communication system in which sequence numbers of radio packets transmitted to first and second radio base stations are managed independently to perform hand-off, when the hand-off is performed while a plurality of fragmented radio packets are transmitted, a mobile device applies sequence numbers of radio packets managed by the first radio base station after the hand-off is performed and applies sequence numbers of radio packets managed by the second radio base station after completion of transmission of the plurality of radio packets. The radio base station managing radio packets is identified on the basis of the sequence numbers managed in each base station upon restoration and data is restored. | 10-02-2008 |
| 20090016265 | RADIO COMMUNICATION SYSTEM, MOBILE STATION, AND RADIO BASE STATION - A radio communication system of an HARQ method that makes an HARQ transmission interval of subpackets appropriate and reduces data transmission delay resulting from subpacket retransmission. In the radio communication system in which a packet is transmitted and receives with the HARQ method between a base station and multiple radio mobile stations, each of the base station and the multiple radio mobile stations has: a packet transmission circuit for transmitting subpackets in predetermined intervals; a packet reception circuit for repeating decoding processing by combining a newly received subpacket and a previously received former subpacket until an original packet is successfully decoded; and a HARQ control equipped with a function of, for packet communication whose data length is short, transmitting a subpacket or response from the packet transmission circuit in an HARQ transmission interval that is shortened from the HARQ transmission interval of the normal mode. | 01-15-2009 |
| 20090180419 | INFORMATION TRANSMITTING METHOD AND INFORMATION TRANSMITTING SYSTEM - An information transmitting method including; determining, on a basis of a packet error rate from a master station to slave stations, a number of times of multicast transmission in accordance with an expected value of a number of slave stations that transmit a retransmission request, an expected value of a number of retransmitted packets responding to the retransmission request, or a probability that the slave stations receive all packets forming information; notifying determined number of times of multicast transmission to the slave stations; and transmitting, to plural slave stations in multicast, same information formed of plural packets the determined times of multicast transmission. | 07-16-2009 |
| 20090180420 | INFORMATION TRANSMITTING METHOD AND INFORMATION TRANSMITTING SYSTEM - A slave station which transmits/receives signals to/from a master station, the slave station includes: a transmitting unit and receiving unit for transmitting/receiving signals regarding the master station; a storing unit; an input unit; wherein under a control by a control unit, the transmitting unit transmits a transmission request for transmitting multicast data to the master station in accordance with a timing of power-on or an input by the input unit; the receiving unit receives information of a number of times of transmission for requested multicast data from the master station and stores the number in the storing unit; and after receiving the multicast data the number of times of transmission stored in the storing unit, the control unit determines presence of absence of lacking data which have not been received and, transmits a retransmission request for requesting the lacking data in a case of presence the lacking data. | 07-16-2009 |
| 20090296631 | SYNCHRONOUS DELIVERY METHOD - An aggregation device performs a synchronous processing so that a synchronous delivery may be made from a plurality of base stations through a broadcasting channel. A BSN ( | 12-03-2009 |
| 20100040013 | WIRELESS COMMUNICATION SYSTEM AND BASE STATION - Admission control wireless resources including abase station which obtains a down wireless resource available rate based on a down QoS requested bandwidth B | 02-18-2010 |
| 20100103817 | WIRELESS COMMUNICATION SYSTEM AND BASE STATION - Admission control wireless resources including abase station which obtains a down wireless resource available rate based on a down QoS requested bandwidth B | 04-29-2010 |
| 20100202342 | AREA MANAGEMENT SYSTEM - A transmission area is specified flexibly in accordance with the contents of a flow. An area identification number (SHOG) is specified for each interlaced stream of wireless base stations. The same flow is sent at the same timing (or substantially at the same timing) in the interlaced stream specified for the same SHOG. A wireless terminal determines a neighbor sector or a neighbor wireless base station sending the same flow, in accordance with information given from the wireless base stations, and receives and combines the flows. | 08-12-2010 |
| 20100227634 | ADJOINING BASE STATION DETERMINING METHOD AND MANAGEMENT DEVICE - A novel method for automatically determining adjoining base stations and storing the information on the adjoining base stations in these base stations is provided which, when a new base station is deployed, immediately sets the adjoining base station information and does not consume wireless resources. This method introduces a management device which, in automatically determining adjoining base stations, executes a decision logic that determines two base stations to be adjoining each other when the distance between the two base stations is smaller than the sum of the radii of coverage of the two base stations. | 09-09-2010 |
| 20110010592 | INFORMATION TRANSMITTING METHOD AND INFORMATION TRANSMITTING SYSTEM - Information transmitting arrangements for transmitting information through a plurality of base stations from a master station to a plurality of slave stations which communicate with the base stations. | 01-13-2011 |
| 20110167264 | DECRYPTION-KEY DISTRIBUTION METHOD AND AUTHENTICATION APPARATUS - A decryption key for decrypting data from an access node is distributed to an access terminal intending to receive the data. An authentication unit receives a message for terminal authentication including a terminal identifier from the terminal and authenticates the terminal. The authentication unit refers to a content registration table having stored in advance the content type of a content which the terminal can receive, in association with the terminal identifier, according to the received terminal identifier to obtain a corresponding content type. The authentication unit refers to a decryption data base having stored in advance a decryption key and its valid period in association with a content type, according to the obtained content type to obtain a corresponding decryption key and valid period. The authentication unit sends an authentication result and the decryption key and valid period to the terminal or to a packet control unit. | 07-07-2011 |
