Description of the Invention: [Technical Field] The present invention relates to a transmission method for a Bluetooth system and a related device thereof, and more particularly to a transmission method for an active transmission packet of a Bluetooth intra-domain device and Its related devices. [Prior Art] The Bluetooth system is a wireless short-range communication system. The micro-network (the minimum net material level, k (TimeDivisiQnDuplexing) (10), let a silk (Den Deweee) and shirt seven_device (Can read (4) Communicate messages to each other. The blue county system divides the communication time of the physical layer channel into a continuous time slot'. The time slot is marked according to the clock of the main device, and the even time slot is used as the "master-pak" (Master- To-Slave) time slot, and odd time slot as "servant-main" (10). Her gamma time slot. In the transmission timing, the domain device alternately transmits the packet, and the device starts on the even-numbered slot. The packet transmission of the device, the feeding device can only start on the odd time slot - the packet transmission of the simple master device is multiplexed and time-multiplexed. Now the county is turned over to the humanized Jieqiu (^ ce On the keyboard, the mouse, the earphone and the joystick, the main function is to receive the input of the j action tb such as the slit, the slippery (four) and the inductive rocker. The unpredictability of these actions, Therefore, in the case of multiple humanized interface devices 201108808 It is necessary to use the polling inquiry (p〇Iling) to confirm whether the humanized interface device has a change to the user. [gt. 1] FIG. 1 is a schematic diagram of the transmission timing of the conventional Bluetooth system. In the micro-network, a computer host (main device) communicates with the keyboard and the snorkeling device. In the communication time, the time slot κ, (κ+2), (κ+4). +ι〇) is the "master-servant" time slot (even time slot), and the time slot (Κ+1), (Κ+3)...(K+ll) ^"儒-主" time slot (odd time) In the first figure, the computer host in turn asks the key 'and / month mouse' to transmit the packet ΡΡΚ1 to _, and to receive the reply packet of the keyboard in the time slot (Κ+1). Then, the time slot (Μ)~(κ+4) transmits an inquiry packet ΡΡΚ2 to the mouse, and receives the slipping reply packet in the time slot (κ+5)~(κ+6). Then, due to the computer domain only The yarn can be transmitted on the slot at even time: therefore, the 4th time slot (κ+8) starts to transmit an inquiry packet ρρκ3 to the keyboard. Similarly, because the inquiry packet ΡΡΚ3 occupies the time slot (Κ+8)~(Κ+9 ) Therefore, the keyboard must wait until the time slot (Κ+11) to reply to the host computer. It can be seen from the above that 'in the conventional Bluetooth system, the 'servant transmission behavior is subject to the main device' does not have a transmission self-record. Also, in order to convey The ship's data must be used to transfer packets and consume more radio resources. [Invention] Therefore, the main purpose of the present invention is to provide a transmission method for allowing a servant device to actively transmit a packet and Device, low cost of wireless resources. 201108808 Cost--the transmission method of reducing the consumption of wireless resources in the servant system's servant's method includes the setting of the communication time, the communication time includes at least one time slot Self-sticking, the receiving time slot is the transmission time slot, and the sigh conversion is the active time slot window.

Therefore, in the active slot window frame, the servant device can actively transmit the packet without waiting for the inquiry of the master device. "So, not only the wireless resources used by the master device for inquiry can be saved" but also the communication between the domain devices is improved. effectiveness. Because of the same secrets in the same - _ device secret, in the embodiment of the bribe, the servant device 疋 according to the - main | set of Wei set information mosquito active slot window frame. In this case, the present invention provides a flow of the "master device" to implement the active transmission function of the county. Please refer to FIG. 3, which is a schematic diagram of the present invention-flow 3(). The process 30 can cooperate with the process 2〇, and includes the following steps: Step 300: Start. Step 310: Determine a active time slot window frame at the time of communication. Step 320: Generate a function setting message according to the determined active time slot window frame. Step 330: Transfer the function setting message to the servant device. Step 340: During the active time slot window frame, the transfer time slot ("master-servo" time slot) is the receiving time slot ("servant-master" time slot) to listen to the blue seal 201108808 from the servant device. 350: End. According to the process 30, the service device of the present invention selects the active time frame and selects the active function setting message, and generates a related function setting message, which is sent to the servant device active transmission function setting. During the active slot window period 1 all the transfer slots ("master-servo" slots) are converted to receive slots ("Fly-Main" ^) to listen to the blue package from the servant. In the active setting of the active transmission function, the main device can participate in the wire-shaking device, and decides the order of transmission between the servants in the slot window frame. In the active time slot window frame, the ^__ packet is confirmed, and in the case of the group and the implicit collection time, the main device can be temporarily - (Temporary Reserved Time Division Duplex Slot ^rvd) Then, in each tentative time-sharing and multi-work slot area, a fixed time slot frame is set up for a long time, and the device is also considered to be a slave. Please refer to the fourth Γ == communication time configuration of the active transmission function of the present invention - the schematic diagram of the embodiment of the "law Γ two time slots, that is, the servant of the label G" or the servant-master time slot of the label. For the servant device, 〇, the time slot is the receiving time slot, and ^ is = time slot 14 4 succinctly describes two consecutive tentative time-division multi-hour slot areas B, the mother-interval contains - The active time slot window frame and the time slot of the active time slot window frame slot window frame are arranged according to the time slot configuration of the Xizhi Bluetooth system, and the time slots are alternately arranged by the "main-servant"-main" time slot, and the training needs to pass through the main device. The inquiry can pass the package, 201108808, and the "master-servant" time slot of the active slot window frame has been converted into the "servant-master" time slot. The servant device sets the message according to the function, and uses the active time slot window frame. One or more, 丨, time slots actively transmit the Bluetooth packet to the primary device. The function setting message of the present invention contains the relevant parameter values of the active transmission function, which are usually generated by the host device and transmitted to the servant device by means of unicast. Please refer to Figures 5 to 7'. Figures 5 to 7 are diagrams of the message exchange timing used to initiate the active transmission function of the present invention. In Fig. 5, the servant device actively transmits a request message LMP_ReqRTDD_Service to request the master device to use the active transmission function. When the main device accepts the request of the servant device, it replies with a function setting message MLMP_Accepted, and the servant device starts the active transmission function according to the parameter content included in the function setting message MLMP-Accepted, such as setting the active time slot window frame. In Fig. 6, the main device transmits a function setting message LMP_RTDD_Cfg requesting the servant device to activate the active transmission function, and the servant device replies with an acceptance message SLMP-Accepted to the master device to confirm the acceptance request. In Fig. 7, the master servant device uses the function setting message • LMP_RTDD—Cfg and the request message LMP_ReqRTDD—Service to negotiate the parameter inner valley. When the servant device disagrees with the parameter content indicated by the master device, it can reply with an entrained reference parameter content. The request message LMP-ReqRTDD_Service, when the main device does not agree with the reference parameter content, can retransmit a function setting message LMP_RTDD_Cfg entraining the new reference parameter content. Negotiating the procedure until the servant responds to the message SLMP-Accepted, indicating that the two parties have successfully negotiated, and the servant will use the parameter content indicated by the master last time. Conversely, if the servant responds with a rejection message SLMP_Not_Accepted, it means that the negotiation fails and the negotiation procedure is aborted. 201108808 The request message LMP_ReqRTDD_Service may include the parameters Max Desired RTDD Time and Min Desired_RTDD_Time, the two parameter length 2 bits 'in time slot units, respectively providing the maximum and minimum values of the acceptable provisional time-division multiplex slot interval to the master device 'Or the maximum and minimum values of acceptable active slot frames, respectively, depending on system requirements. The function settings and LMP_RTDD_Cfg can include the parameters RTDD Interval, RTDDJWindow, RTDDJnstant and RTDD-TokenAddr. The parameters RTDD_Interval and RTDD-Window can be represented by 2 bits, which are in units of time slots, indicating the size of the tentative time-division multi-hour slot and active day-to-day frame respectively; the parameter RTDD”nstant is composed of 4 bits and is used to indicate The next time the main device Bluetooth clock is turned on, that is, the servant device knows when the active time slot window frame ends; the length of the parameter RTDD-IbkenAddr is! The bit ' is used to indicate the order of transmission between the next active slot frame and other servant devices with active transfer capabilities. In addition, according to the parameter RTDD-TokenAddr' each servant device adjusts the order of transmitting packets in each active slot window frame.

In order to clarify the two embodiments, the following embodiments will be described as a transmission between the main device and a plurality of Confucian devices. Please refer to the first, third drawing. FIG. 1 is a main device μ servant device according to the first embodiment of the present invention. The transmission timing of the ~ is called _. In the communication of the 1st figure, there are two tentative time-division multi-time slot sections, which include - active time slot window pivot 3 RTDDWin_l and a non-active time slot window frame BTDDWin Bu another package time slot window frame RTDDWin -2 and - non-active time slot window frame MDDwin active window frame RTDDWinJ and RTDDWin_2 both contain four transmission time slots for the servant device slot 11 201108808 SLV1 ~ SLV4 active transmission packet. In the active time slot window frame RTDDWinJ, the servant device SLV1 is used as the opening, and the Dm lion blueberry package is transmitted to the main device MAS with other duties. The data characteristics of a humanized interface device such as a mouse or keyboard, the DM1 or DH1 type of Bluetooth packet can meet the demand, and the header includes a 68-bit access code (Access Code). Since the blue-and-white packet format of the DM1 or DH1 type should be well known to those of ordinary skill in the art, the relevant format content is no longer Wei. In order to balance the transmission efficiency of the parent servant device, the present invention can be used in every next active slot window frame servant device, periodically as the start end, as shown in the first figure, in the next active time slot window frame RTDDWin - 2 towel, by weaving SLV2 as the starting end, and the SLV3, SLV4 and SLV1 are sequentially transmitted with the blue-and-white packet, and then the three active time-slot window frames (not shown) are respectively used by the servant device SLV3 , SLV4 and SLV1 come to the start end. The servant devices SLV1~SLV4 can automatically adjust the transmission sequence in each active time slot window frame according to their own transmission address and parameter RTDD_IbkenAddr. In other words, the predetermined transmission time slot of the servant devices SLV1 to SLV4 is periodically changed in accordance with the period of the tentative time division multi-hour slot area. In the inactive time slot frame BTDDWin_l and BTDDWin-2, the servant devices SLV1 to SLV4 and the master device MAS respectively perform groups corresponding to the active time slot frame RTDDWin_l & RTDDWin-2 and implicitly confirm the program. The fine concept is as follows _. First, after the end of the active time slot window frame, the first "master-servant" time slot, the health check ~ listens to the first packet sent by the master device MAS, and then can be divided into three emotions, the H domain is sent to the MAS. The first packet, which contains the logical transmission 12 201108808, the address is not a miscellaneous miscellaneous shirt of the county SLV1 ~ SLV4, or the first packet is - when the broadcast packet, the servant device _ ~ 黯 active The packets transmitted in the box have been successfully received by the primary device. For example, the SV4 has a logical transfer address W~u Addr4, and the logical hash of the first packet is Lt-Addr5, and the packets of the hard-to-set SLV1~SLV4 are all transport handles, that is, the handle is confirmed ( PGsitivelyAek_iedged). Case 2: If the first logical listener contains the logical transmission address of the SLV4, it means that in the active slot window, (1) is indicated by the first packet. Fine (four) package, that is, money confirmation (10) fine kiss Adcn〇 Wledged); (ii) more secret package _ device seal _ send success · (5) servant device that transmits the packet late must enter an inquiry waiting state, continue to wait for the main device The notification, that the logical transmission address of the packet transmitted by the straightening device does not belong to the logical transmission address of any servant device SLV1~SLV4, indicates that the servant device slvi~ is said to be a white packet. For example, if the address of the first packet is U_Addr3, it means that the packets of the servant dragon~_ are successfully transmitted, the servant device SLV2 needs to retransmit the packet, and the servant device enters the inquiry waiting state.凊/Brother right until the start of the next active slot window frame, the servant device sm~SLV4 white does not take any packet of the master device, it means that the packets of the servant devices sm~SLV4 are successfully received, meaning implicit Confirm receipt. Therefore, from the standpoint of the servant sun ~ hidden, a suitable acceptance confirmation procedure must include at least the following steps and principles, taking the servant device SLV2 as an example: (); after the active time slot window is closed, enter a listening The status of the Bluetooth packet from the main device MAS 201108808; (2) When the packet is not heard in the inactive slot window frame, it is judged that the transmission packet is in the successful receiving state; (3) successfully heard from the main device The first blue-brain packet, which includes a transmission time of the Lt-Ad尬 transmission, and the triggering of the axis package is a successful receipt state; (4) successfully listening to the first blue-seal sentence, When it is a broadcast type packet, it judges that the transmission packet is in a successful receiving state; (5) when successfully listening to the first Bluetooth packet, which also includes the logical transmission address Lt_Addr2, it is determined that the transmission packet needs to be retransmitted; (6) after successfully listening to the first - a sprouting packet, which includes a logical transmission address within a range of -u-a, enters an inquiry waiting state; and (7) when receiving an incoming blueprint packet from the primary device in the inquiry waiting state, 3), (5) and (6) The principle of judgment. The "logical transmission address beyond Lt_Addr2" of the description (3) indicates that the transmission order is after the servant device SLV2 or does not belong to any of the servant devices SLV1 to SLV4 _ series transmission address. The "logical transfer address in the range of Lt_Addr2" of the relative '(6) indicates the logical transfer address before the slave device SLV2. In addition, please refer to FIG. 11, which is a transmission timing diagram of the main device MAS and the servants SLV1 S SLV4 according to the second embodiment of the present invention. In the figure u, the first and third time slots of the active time slot frame RTDDWin-1 and RTDDWin_2 are converted from the "main-201108808 servant" time slot to the "servant~-master" time slot. The u_th": slot, and the second and fourth slots originally turned out to be "the Confucian device uses a shorter access drink (like the place = the second and fourth order of the servant mi ~ Pkt4. Because of the biography The encapsulation state of the nth picture does not listen to any packet and the fourth time slot. The conventional device is also in a transmission and does not affect the conventional servant device. Therefore, the present invention is difficult to transmit a short access code packet transmission. Power, delete her (4) "Set can save. Please special f' silk ride care program towel to pass the series · & as. :: only, - examples, the field has two:: Second, built ^The information of the relative relationship of the device is used as the sequence index. In addition, the present invention can perform multi-time slot transmission in the active time slot window frame, and is not limited to one-length packet transmission. 凊Refer to the 12th, 12th, The invention is directed to an embodiment of a communication device 1200 for a Bluetooth device. The communication device 12 (8) includes a radio frequency transceiver (2), a baseband circuit 1220, a central processing unit g 123, and a storage device 124. The radio frequency transceiver The 1210 allows the Bluetooth device to transmit and receive wireless signals. The central processing unit η can execute a code 125〇 stored in the storage device 1240 to control the radio frequency transceiver 1210, the base frequency circuit 1220, and the storage device 1240. The code 125 includes a radio protocol layer 1252 and a link control ( LinkContro LC) protocol layer 1254 and a Link Management Protoco (LMP) layer 1256. The present invention provides an active transfer function program 1258 in code 1250, which is executed by the central processing unit 1230 201108808 to implement the main device. The operation of the active transmission function on the upper or the servant device. When the communication device 1200 is used for a Bluetooth device, the active transmission function program 1258 is mainly used to implement the process 20 for the servant device to actively take the active time slot window frame. The packet is transmitted to the master device. In this case, the radio protocol layer 1252 mainly performs frequency synthesis and data conversion with the radio frequency transceiver 1210 to transmit and receive packets on the physical channel. The link control protocol layer 1254 mainly cooperates with the baseband circuit 1220. Responsible for identifying the time slot as the transmission or receiving time slot, and setting the active time slot window frame according to the function setting message. The protocol layer 1256 is used to interpret and set related information of the active transmission function, for example, to interpret the function setting information from the host device, and also to manage the relevant parameters of the active transmission function, such as the aforementioned parameters Max-Desired-RTDD-Time and RTDD_InStant. By the management of the parameters, the link management agreement layer 950 is responsible for establishing, releasing, and managing the connection with the host device. Since the communication device 12〇〇 utilizes the active transfer function program 1258, it can be used to implement the process 2G. Refer to the foregoing (as described in Figures 2 and 4 to 11). When the communication device 1200 is used for the Bluetooth primary device, the active transmission function program 1258 is mainly used for the real thief 3G. In this case, the link (4) agreement layer 1254 is mainly matched. The baseband circuit 122 carefully recognizes (4) the transmission or reception time slot, and sets the active time slot window frame chain financial agreement layer 1256 to generate the start and close messages of the main transfer function, etc. _ and the active transfer function of the change. Since the δί1 device 1200 can be used to implement the process 30 by using the active transfer function program (10), the detailed operation of the active transfer function can be referred to the above (as described in the third and fourth to n-th views). 16 201108808 As described above, the present invention establishes an active time slot window frame in the communication time of the Bluetooth system, and the packet transmission wheel of the device is not subject to the transmission behavior of the main device. In this case, the main device can save the packet of the _ inquiry, so she can save the source of the squad. Correction, the device of the present day can compare the packet of the access code without affecting the compatibility with the conventional health, and can save wireless resources.
