To describe the present invention about preferred embodiment in specific environment below, specific environment promptly allows peripherals to append to the UWB wireless connections of computer system, and peripherals has Wireless Keyboard or mouse.One UWB wireless connections are medium that senior data rate wireless connections to the extra-high-speed level are used, and wherein, the bandwidth of transmission signals quite or exceed 0.25 times channel width.Now, the enforcement of UWB wireless network can provide the data bandwidth of 500 megabyte per seconds (500MB/S).Even expansion UWB also allows bigger data bandwidth.The UWB wireless network that has many different editions is such as all describing to some extent in U.S. Pat 2671896, US3662316, US3806795, US5337054, US5677927 and International Patent Application WO 019344 and WO0193443.Here come by reference in conjunction with these patents.The present invention also can support other peripherals, such as modulator-demodular unit, network adapter, other indicating equipment, audio player and mass-memory unit or the like.
With reference to Figure 1A, an exemplary UWB network 100 with Wireless Communication Equipment is described.This standard UWB network comprises two network equipments, a UWB transceiver unit 105 and the 2nd UWB transceiver unit 110.Rely on the concrete enforcement of network, two UWB transceiver units 105 and 110 can be server in two peer sides in the peer-to-peer network, the client/server network and main frame and the appurtenant machine in client computer or the master-slave network.
With reference to Figure 1B, second kind of second exemplary UWB network 150 with Wireless Communication Equipment described.This second exemplary UWB network comprises four network equipments: UWB transceiver 155 and other three UWB transceivers 160,165 and 170.This second exemplary UWB network 150 or to be shown as be client/server network, or be shown as master-slave network, wherein a UWB transceiver 155 uses as server (perhaps main frame), and other three UWB transceivers 160,165 and 170 then use as client computer (or appurtenant machine).When as master-slave network, in other three UWB transceivers each can only communicate (communicating by letter between with dashed lines 162,167 and 172 explanation the one UWB transceivers and other three UWB transceivers) with a UWB transceiver 155, rather than mutual communication to each other.Notice that Figure 1A and 1B have illustrated the UWB wireless network (two or four) of the UWB transceiver with some number.This only is to play illustration purpose, and the number of described UWB transceiver can be arbitrarily fully.
With reference now to Fig. 2,, describes according to the preferred embodiment of the present invention, has the wireless computer system 205 that appends to the peripherals on the computer system.Peripherals 210 appends on the computer system 205 by wireless connections 215 (connecting such as the UWB wireless network).These wireless connections 215 have replaced wired connection effectively, when peripherals 210 and relative computer system 205 being begun to be configured, moving and place, can allow great dirigibility.
With reference to figure 3, according to the preferred embodiment of the present invention UWB network 200 is described, it disposes according to the mode that is easy to peripherals 310 is appended to computer system.If UWB network 200 as client/server network (perhaps as master-slave network), so just can obtain maximum dirigibility, preferably the UWB transceiver 305 (being positioned at inside computer system) of UWB network 200 is as server (perhaps main frame).By the UWB transceiver is so disposed, the peripherals (such as peripherals 310) that any UWB enables just can be connected with UWB transceiver 305 (as server or main frame), and enters thus in the computer system scope.If UWB transceiver 305 is arranged in computer system, and use as client computer (or appurtenant machine), just might make the peripherals that self (as client computer or subordinate) has the UWB transceiver enter the opereating specification of computer system, and because the both just make them communicate by letter as client computer (or subordinate) unit.
Yet because client-server (main frame and appurtenant machine) may convert task in some networks, the UWB transceiver 305 that is arranged in computer system so just might become client computer (or appurtenant machine).Yet, for preventing above-described situation, it is the situation that client computer (or appurtenant machine) peripherals enters the computer system scope that can not communicate by letter its client computer (or appurtenant machine) unit, preferably, under computer system has situation as the UWB transceiver of client computer (or appurtenant machine) unit, in case existing communication finishes, the UWB transceiver just automatically reverts to server (or main frame) unit.
With reference to figure 4A, to describe and to have by wireless connections 412, especially UWB wireless connections are attached to the theory diagram of the computer system 405 of the peripherals 410 on the computer system.As previously mentioned, peripherals 410 is used as arbitrary client computer (or appurtenant machine) equipment usually in the UWB network.Perhaps, peripherals 410 also can be as the operation of equity side in peer-to-peer network.Fig. 4 illustrates 10 fens typical situations, and wherein peripherals 410, such as Wireless Keyboard or mouse, are connected on the computer system 405 by wireless connections 415.For describing more simply, can be attached to the peripherals of other type on the computer system 405 in a similar manner, such as comprising printer, image device (scanner, static state and dynamic gamma camera or the like), individual digital utility appliance, multimedia equipment (MP3 player, wireless speaker or the like), sensor, telemetry equipment or the like.
For example, the information that sends to computer system 405 from peripherals 410 can be by following path: peripherals 410 generation information, and send UWB transceiver 415 to by peripherals 410.UWB transceiver 415 receives the operating system 425 that transmission information then provides it to computer system.Yet, since the communication system that UWB transceiver 415 is not supported, UWB transceiver 415 unlikely and operating system 425 direct communications so.On the contrary, UWB transceiver 415 may connect a communication bus 422, is transferred to the processor 435 of computer system again by this communication bus.
The UWB wireless network uses the information according to specific format to communicate, and transmits with specific signaling protocol.Communication bus 422 can not use the signaling protocol with UWB wireless network compatibility.Therefore, just need interface 420 between employed signaling protocol of UWB wireless network and communication bus 422 employed signaling protocols, to carry out conversion.After interface 420 conversions, information is provided for operating system 425 again.Equally very usual is that another time of the informational needs conversion on the communication bus 422 after the conversion of carrying is so that convert thereof into the signaling protocol compatible mutually with operating system 425 employed signaling protocols.Conversion is for the second time realized by second interface 424.
The information that peripherals 410 sends will experience twice different conversion converting thereof into required compatible protocol of particular moment, yet, under most of situation, be included in data in the information self all without conversion.Such as, the UWB information that peripherals sends keeps the UWB form.Therefore, for operating system 425 can pack processing be contained in information in the UWB information, just need a protocol software stack 430.The function of this protocol software stack 430 is to convert operating system 430 intelligible data to UWB form information encoded.Generally speaking, protocol software stack 430 is two-way operation, from the UWB format conversion with convert the UWB form to.
After 430 conversions of protocol software stack, information will offer processor 435 by operating system 425, and operating system 42 is taked suitable action.Generally speaking, information is provided for processor 435 from operating system 425 with the interruption form, and interruption can cause processor 435 its current ongoing information of time-out to read and handle.Similarly, 410 information will produce the incident of reverse order but from processor 435 to peripherals.
In some cases, between UWB transceiver 415 and processor 435, several communication buss can be arranged.Such as, if UWB transceiver 415 is connected to USB (universal serial bus) (USB), USB is the communication bus that nowadays generally uses in the computer environment, USB will be connected on the internal bus of computing machine self so, such as peripherals connecting interface (PCI) bus.
With reference now to Fig. 4 B,, show the theory diagram of a typical modem computer systems 455, this system has one by wireless connections 462, especially is attached to peripherals 460 on the computer system by the UWB wireless connections.Shown in Fig. 4 B, computer system 455 has especially and allows other UWB transceiver (and the peripherals that comprises them) to be connected to UWB transceiver 465 on the computer system 455.UWB transceiver 465 is connected on the computer system 455 by USB (universal serial bus) (USB) 472.USB 472 is the communication buss that are present in most now computer systems.It allows additional plurality of devices, comprises network adapter, such as UWB transceiver 465 (can be effective as the UWB network adapter).
UWB transceiver 465 is used the UWB forms and signaling protocol communicates, and therefore for using USB 472, just needs interface 455 so that incompatible UWB and the conversion between the USB signaling protocol to be provided.Though USB 472 is widely used communication buss, yet it can not be used for carrying out direct communication with the processor 485 of computer system 455 usually.Opposite, processor 485 communicates with the equipment and the peripherals that are connected thereon by peripheral device component interconnect port (PCI) 476 usually.PCI 476 is high-speed communication buses, is used for by processor 485 and is connected peripherals on the computer system 455 and other communication bus (such as USB 472) communicates.Need another interface the information translation of PCI form and signaling protocol to be become form and the signaling protocol that to be understood by processor 485 equally.Need the 3rd interface 474 between USB and PCI form and signaling protocol, to change.Notice that in Fig. 4 A the protocol software stack 482 that need be arranged in the operating system 480 of computer system is changed the actual information that is transferred to (or from) processor 485.
Need the use agreement software stack so that carry out information translation, be because if information without conversion, they just can not be received device understanding.Yet,, in main computer unit 465 installation processes, just it need be added in the operating system so if operating system 480 does not make up protocol software stack 485.As previously mentioned, Add-ons is introduced operating system only can make operating system more unstable, and reduce performance of computer systems.
As shown in Figure 5, described the theory diagram according to the computer system 505 of the preferred embodiment of the present invention, this system has one by wireless connections 512, especially is attached to peripherals 510 on the computer system 505 by the UWB wireless connections.Computer system 505 has the UWB transceiver 515 that allows computer system 505 connection peripherals, the peripherals 510 of peripherals as having built-in UWB transceiver especially.UWB transceiver 515 is connected to the remainder of computer system 505 by communication bus 522, and interface 520 is used for carrying out between the form of message of UWB message and communication bus 522 and the signaling protocol conversion of any necessity.
As mentioned above, the theory diagram of Fig. 5 is the same with the theory diagram of Fig. 4 A.Yet, according to a preferred embodiment of the invention, interface 520 is also not only changed any form and the signaling protocol difference of UWB information and communication bus 522 information, but also the information translation of UWB form is become the form that can be understood by the processor 528 of computer system 505.Interface 520 can change information over to produce communication bus form.Such as, if communication bus 522 is USB, interface 520 just can become the UWB information translation USB information so, vice versa.
Because computer system 505 has been supported communication bus 522, so the operating system 526 of computer system has not just needed to increase protocol software stack again (the described computer system of image pattern 4A and 4B is done).In fact, from the required protocol software stack of communication bus 522 transitional informations the loading of operating system 526.
With reference now to Fig. 6,, described according to the preferred embodiment of the present invention, made the part detailed view of UWB transceiver 610 that UWB information and USB information changes mutually, USB 620, interface 630.UWB transceiver 610 sends information or therefrom receives information from the UWB wireless device, and USB 620 is the high-speed communication buses in the computer system that allows USB 620 wired USB of appending to 620 are added self.Interface 630 is used for UWB transceiver 610 and 620 information that pass mutually of USB are changed and conversion.Conversion and conversion are carried out by interface 630, and the information that allows to start from interface 630 1 ends (or UWB transceiver 610 or USB 620) is sent to the other end.
Passing from UWB transceiver 610 can be by low level path (LOWER PATH) transmission of interface 630 to the information of computer system processor (not shown), wherein this information by UWB to the USB converter from the UWB form and signaling protocol be converted and be transformed into USB form and signaling protocol.According to the preferred embodiment of the present invention, UWB not only becomes the UWB information translation form with USB 620 compatibilities to USB converter 640, and converts actual information to USB information.Before, most of interface can be packaged into information the compatible information form usually.Usually can adopt UWB information and they are inserted in the USB information to the USB converter such as, aforementioned UWB, the multiple partial that separates UWB information is so that make it can be fit to USB information on demand.Will be from the information of USB 620 to UWB transceivers 610 along high-order path (UPPER PATH) transmission of interface 630, wherein information is converted and is transformed into UWB information.
