Advantageous Effects
[20] As described above, in a method and apparatus for adjusting a bandwidth of a device according to the present invention, when a device connected by a P2P method used with WUSB cannot provide a sufficient service with a currently allocated bandwidth, the bandwidth is adjusted.
[21] By doing this, i.e., flexibly adjusting bandwidths of a default link and a reverse link through which devices are connected, QoS of communication in a device connected by the P2P method can be improved.
[22] While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those of ordinary skill in the art that various changes in form and detail may be made therein without departing from the spirit and scope of the present invention as defined by the following claims.
Description of Drawings
[23] The above and other features and advantages of the present invention will become more apparent by describing in detail exemplary embodiments thereof with reference to the attached drawings in which:
[24] FlG. 1 is a conceptual diagram of devices connected by wireless universal serial bus (WUSB) using a P2P method;
[25] FlG. 2 is a flowchart illustrating a method of adjusting a bandwidth of a device according to an embodiment of the present invention;
[26] FlG. 3 is a block diagram of a bandwidth adjustment apparatus of a first device and a second device according to an embodiment of the present invention; and
[27] FIGS. 4 A through 4C are reference diagrams for explaining a method of adjusting a bandwidth of a device according to an embodiment of the present invention.
Mode for Invention
[28] The present invention will now be described more fully with reference to the accompanying drawings, in which exemplary embodiments of the invention are shown.
[29] FlG. 1 is a conceptual diagram of devices 100 and 110 connected by wireless universal serial bus (WUSB) using a P2P method.
[30] FlG. 2 is a flowchart illustrating a method of adjusting a bandwidth of a device according to an embodiment of the present invention.
[31] Referring to FIGS. 1 and 2, in operation 200, a default link 120 by which a first device 100 operates as a host and a second device 110 operates as a device is generated. When the first device 100 operates as a host using a microscheduled management command (MMC), the second device 110 is associated with the first device 100 by transmitting a connect device notification message to the first device 100 in response to the MMC.
[32] In operation 210, a reverse link 130 by which the second device 110 operates as a host and the first device 100 operates as a device is generated. When the second device 110 operates as a host with the remaining bandwidth and transmits an MMC to the first device 100, the first device 100 is associated with the second device 110 by transmitting a connect device notification message to the second device 110 in response to the MMC.
[33] In operation 220, the first device 100 determines whether an application operating as a host can provide sufficient quality of service (QoS) with the currently allocated bandwidth.
[34] If it is determined that the application operating as a host cannot provide sufficient
QoS with the currently allocated bandwidth, in operation 230, the first device 100 requests the second device 110 to additionally allocate a bandwidth, which is not used by the second device 110, to the first device 100. In this case, the first device 100 performs a control transfer using a PASS-MAS (medium access slot) command for transferring the number of MASs additionally needed.
[35] In operation 240, the second device 110 allocates a predetermined bandwidth to the first device 100 in response to the request from the first device 100. The bandwidth allocated by the second device 110 may be a remaining bandwidth excluding the bandwidth to be used by the second device 110. In this case, the second device 110 transmits location information of supportable MASs excluding the bandwidth to be used by the second device 110 based on the number of MASs transferred by the PASS-MAS command from the first device 100. FlG. 4A illustrates data transmitted from the second device 110 to the first device 100 in operation 240. In FlG. 4A, 'bmRe- questType' is illustrated in FlG. 4B, 'w Value' denotes the number of MASs requested by the first device 100, 'wLength' denotes the length of distributed reservation protocol (DRP) allocation, and 'Data' denotes information on the MASs allocated by the second device 110.
[36] In operation 250, the first device 100 inserts a DRP information element (IE) corresponding to DRP allocation changed by the predetermined bandwidth allocated by the second device 110 into a beacon and broadcasts the beacon.
[37] In operation 260, the first device 100 communicates via WUSB using a bandwidth changed by including the predetermined bandwidth allocated by the second device 110.
[38] FIG. 3 is a block diagram of a bandwidth adjustment apparatus of the first device
100 and the second device 110 according to an embodiment of the present invention. Referring to FIG. 3, the bandwidth adjustment apparatus includes a bandwidth request unit 101, a bandwidth adjuster 102, a request receiver 111, and a bandwidth allocator 112.
[39] The first device 100 and the second device 110 are associated with each other by the P2P method used with WUSB. That is, the first device 100 and the second device 110 are associated with each other through the default link 120 by which the first device 100 operates as a host and the second device 110 operates as a device and the reverse link 130 by which the second device 110 operates as a host and the first device 100 operates as a device.
[40] The first device 100 includes the bandwidth request unit 101 and the bandwidth adjuster 102.
[41] The bandwidth request unit 101 requests the second device 110 to additionally allocate a bandwidth, which is not used by the second device 110, to the first device 100. Here, the bandwidth request unit 101 performs a control transfer using a PASS-MAS command for transferring the number of MASs additionally needed. In addition, when the first device 100 determines that an application operating as a host cannot provide sufficient QoS with the currently allocated bandwidth, the bandwidth request unit 101 requests the second device 110 to additionally allocate a bandwidth to the first device 100.
[42] The bandwidth adjuster 102 obtains a predetermined bandwidth allocated by the bandwidth allocator 112 of the second device 110.
[43] The second device 110 includes the request receiver 111 and the bandwidth allocator 112.
[44] The request receiver 111 receives a request for additionally allocating a bandwidth from the bandwidth request unit 101 of the first device 100 in the form of a PASS_MAS command.
[45] When the request receiver 111 receives the bandwidth allocation request from the bandwidth request unit 101, the bandwidth allocator 112 allocates a predetermined bandwidth to the first device 100. The bandwidth allocated by the bandwidth allocator 112 may be a remaining bandwidth excluding a bandwidth to be used by the second device 110. In this case, the bandwidth allocator 112 transmits location information of supportable MASs excluding the bandwidth to be used by the second device 110 based on the number of MASs transferred by the PASS-MAS command from the bandwidth request unit 101.
[46] The invention can also be embodied as computer readable codes on a computer
(including any device having an information processing function) readable recording medium. The computer readable recording medium is any data storage device that can store programs or data which can be thereafter read by a computer system. Examples of the computer readable recording medium include read-only memory (ROM), random-access memory (RAM), CD-ROMs, magnetic tapes, hard disks, floppy disks, flash memory, optical data storage devices, and so on.
