摘要:
A terminal on the first network, a gateway device connected between the first and second networks, and a network device on the second network enable the terminal to independently and seamlessly use a plurality of network devices and to seamlessly use a network device on the first network and the network device on the second network. The network device indirectly or directly provides the terminal and the gateway device with terminal behavior information and proxy processing behavior information in which a behavior required to use the device itself is described, or provides the gateway device with gateway functional module information including the terminal behavior information and the proxy processing behavior information.

A sending apparatus includes an encryption unit and a sending unit. The encryption unit encrypts each of data packets on the basis of a frame number of a frame and a determined cryptographic key. The sending unit transmits a frame including the data packets encrypted. A receiving apparatus includes a receiving unit and a decoding unit. The receiving unit receives the frame. The decoding unit decodes each of the data packets on the basis of the frame number of the frame and a determined decoding key.
摘要:
In a relay station, a packet fragmented by a sending station is received. The fragmented packet is selectively further fragmented into a plurality of refragmented packets. Identification information (FSN) is added to each of the refragmented packets and to a non-refragmented packet not fragmented. Each of the packets to which the identification information (FSN) has been added is transmitted to a receiving station. This makes it possible to prevent a confliction of information (FSN) between packets due to the packet refragmentation in the relay station.
摘要:
A relay station for relaying communication between a radio base station which allocates to a terminal an uplink channel for notifying a requested band when any signal sequence out of a predetermined signal sequence group is received from the terminal, and allocates a transmission band according to the requested band notified from the terminal via the channel, and the terminal, including: a transmission unit which sends a specific signal sequence not included in the predetermined signal sequence group, wherein the relation station is allocated a predetermined transmission band by the radio base station, without the relation station is not allocated the uplink channel for notifying the requested band by the radio base station which is received the specific signal sequence.
摘要:
A receiving device includes a packet receiver that is coupled to a plurality of paths, and a packet transmitter that generates reception-acknowledgement information indicating that the packet receiver receives a packet when the packet receiver receives the packet over one of the paths, and that transmits the reception-acknowledgement information to a path that is among the plurality of paths and different from the path over which the packet receiver has received the packet.
摘要:
A mobile communication system including: a first wireless base station; a second wireless base station located within a service area of the first wireless base station and configured to have a service area smaller than the service area of the first wireless base station; a wireless terminal configured to couple to the first or second wireless base stations; and a communication control apparatus; wherein the communication control apparatus controls adjustment of communication parameters of the first wireless base station, instructs the second wireless base station whose communication parameters have been changed to measure a wireless quality of the first wireless base station when changes to the communication parameters of the first wireless base station have occurred, obtains the wireless quality measured by the second wireless base station, and determines whether the communication parameters of the first wireless base station were adjusted based on the wireless quality.
摘要:
A relay station relays packets between a transmitting station and a receiving station, and when a transmission packet affixed with a packet number is received, the relay station generates a divided data unit by dividing the data included in the transmission packet, then generates a divided packet including the divided data unit affixed with the packet number and dividing position information indicating the dividing position of the divided data unit, and transmits the divided packet to the receiving station. Alternatively, the relay station generates a divided data unit by dividing the data in the received transmission packet, then generates a divided packet including the divided data unit affixed with a new packet number, and transmits the divided packet to the receiving station. An ARQ process is executed using the dividing position information or the new packet number included in the divided packet.
摘要:
A relay station that includes a receiving unit acquiring a measurement timing at which a radio terminal measures a reception quality of a radio signal, and a transmitting unit transmitting in said measurement timing a radio signal with which said radio terminal is capable of measuring reception quality.
摘要:
A radio communication method in a radio communication system including a base station apparatus and a terminal apparatus, the method including: generating a public information message including identification information of a surround base station apparatus of the base station apparatus, and instruction information for receiving communication parameter information used to communicate with the terminal and the surround base station apparatus from the surround base station apparatus, by the base station apparatus; transmitting the generated public information message, by the base station apparatus; receiving the public information message, by the terminal apparatus; and receiving the communication parameter information transmitted by the surround base station apparatus based on the instruction information included in the public information message, by the terminal apparatus.
摘要:
In A message exchange method, a wireless terminal transmits to a wireless base station a message parameter which includes identification information identifying a trigger message and a message size indicating the data length of a message, which is to be transmitted from the wireless terminal to the wireless base station. The trigger message is a message to trigger transmission of the message to be transmitted. Next, the wireless base station transmits the trigger message to the wireless terminal, and thereafter allocates to the wireless terminal a wireless bandwidth corresponding to the message size of the message to be transmitted. Further, the wireless base station transmits to the wireless terminal allocation information indicating the allocated wireless bandwidth. Then, the wireless terminal transmits the message to be transmitted, to the wireless base station by using the wireless bandwidth indicated by the allocation information.
