The present invention has an object to prevent an automatic download from overlapping usage of the mobile communication terminal completely or as much as possible.In order to achieve the above-described objective, the present invention provides a mobile communication terminal includes: a wireless communication portion; and a control portion which downloads software via the wireless communication portion from a software distribution apparatus connected to a network, wherein the control portion, when an update operation is conducted by using the downloaded software, displays a screen indicating end of operations of system software of the mobile communication terminal.
摘要:
Regarding an apparatus capable of transmitting data using a high-rate transmission channel having narrow directivity and a low-rate transmission channel having wide directivity, data is not correctly sent in some cases because a communication path for the high-rate transmission channel is easily interrupted. In contrast, it is not possible to realize sending of high-quality data using the low-rate transmission channel. The same data is simultaneously transmitted using the high-rate transmission channel and the low-rate transmission channel. The data that has been received using the high-rate transmission channel or the data that has been received using the low-rate transmission channel is selected in accordance with a state of reception using the high-rate transmission channel.

A WiMAX compatible base station (BS) includes: an allocator unit (10B, 10C) configured to allocate allocation information of the downlink burst (DL-MAP) as transmission information in a first region (MAP region), and to allocate the downlink burst as transmission information in the second region (downlink burst region); and a transmitter unit (10F) configured to transmit the allocation information of the downlink burst with a non-directional beam, and to transmit the downlink burst with a non-directional beam or a directional beam. When detecting an unused region (A) where no transmission information is allocated after allocating the transmission information in the first region and the second region in the frame structure, the allocator unit is configured to reallocate, by use of the detected unused region, the allocation information of the downlink burst as the transmission information in the first region.

摘要:
Communication bands occupied by wireless communication paths extending from a source node to a destination node are determined, and a combination of wireless communication paths is selected based on spatial distances between wireless communication paths from combinations of wireless communication paths in each of which the number of communication bands with respect to a combination of wireless communication paths is smaller than a threshold.
摘要:
A communication network includes a control node and one or more controlled nodes. The control node transmits allocation information, which indicates a non-conflict region of each node in the communication frame, in a non-conflict region allocated to the control node, if an access request has been received from a new node, allocates a non-conflict region of the new node to the communication frame, and updates the allocation information based upon the allocation. The controlled node relays the allocation information in the non-conflict region of the controlled node if the allocation information has been received, and relays the access request in the non-conflict region of the controlled node if the access request has been received. The new node detects the conflict region and non-conflict region of the communication frame based upon the received allocation information, and transmits, in the detected conflict region, the access request to access the communication network.
摘要:
A control apparatus for use in a system in which a transmission source apparatus transmits data to a destination apparatus a plurality of times via a plurality of different communication paths comprising at least one path link each formed by two communication apparatuses directly communicating with each other using at least one of a plurality of antenna radiation patterns, the control apparatus including an acquisition unit configured to acquire communication quality information for each antenna radiation pattern of each communication apparatus forming the path links of the communication paths, a selection unit configured to select a plurality of communication paths exhibiting high communication quality based on the communication quality information acquired by the acquisition unit, and a first allocation unit configured to allocate, to a time slot, a path link of the selected communication paths and an associated antenna radiation pattern for each communication apparatus forming the allocated path link.
摘要:
A radio communication terminal of the present invention determines expected communication speeds used on a forward link on the basis of receiving conditions of carriers Cfw1 to Cfw3 and transmits DRC values indicating the expected communication speeds to radio base stations. When the number of reverse link carriers used for communication on a reverse link is less than the number of radio base stations, the radio communication terminal transmits the speed control values for the radio base is stations by use of a carrier Crv1.
