技术领域technical field

本发明有关于不同装置之间的数据处理(data transaction)，尤其有关于一种利用通信协议来传输/接收另一种通信协议的应用的数据的方法及其装置。The present invention relates to data processing (data transaction) between different devices, and in particular relates to a method for transmitting/receiving application data of another communication protocol using a communication protocol and a device thereof.

背景技术Background technique

随着无线通信(wireless communication)技术的进步，一个装置得以透过无线通信协议(wireless communication protocol)来与另一个装置进行数据传输通信。其中，无线通信协议可例如蓝牙(Bluetooth)、无线兼容认证(wireless fidelity，Wi-Fi)等等。因为蓝牙技术发展得相当早，故已有许多蓝牙应用(Bluetoothapplication)问世，举例来说，点对点通信应用(peer-to-peer communicationapplication)普遍为许多蓝牙装置(例如，移动电话)所支持。对于无线兼容认证技术来说，由于其提出的比蓝牙技术晚，故可用的应用相当少，举例来说，无线兼容认证点对点模式(Wi-Fi ad-hoc mode)为最常使用的应用。由于无线兼容认证直连(Wi-Fi Direct)标准的发展，可允许无线兼容认证装置彼此之间无需无线接入点(access point)即可进行通信，换言之，无线兼容认证直连应用的操作相似于蓝牙应用的操作，举例来说，无线兼容认证直连应用可支持文件/档案共享、打印以及两个无线兼容认证装置之间的同步处理(synchronization)，然而，由于无线兼容认证直连标准是近期所发表，并没有许多无线兼容认证直连应用可供用户来使用。With the advancement of wireless communication technology, a device can communicate with another device for data transmission through a wireless communication protocol. Wherein, the wireless communication protocol may be, for example, Bluetooth (Bluetooth), wireless compatibility certification (wireless fidelity, Wi-Fi) and the like. Because the Bluetooth technology has been developed quite early, many Bluetooth applications have come out. For example, peer-to-peer communication applications are generally supported by many Bluetooth devices (eg, mobile phones). For the wireless compatible authentication technology, since it was proposed later than the Bluetooth technology, there are quite few available applications. For example, the wireless compatible authentication point-to-point mode (Wi-Fi ad-hoc mode) is the most commonly used application. Due to the development of the Wi-Fi Direct standard, it allows Wi-Fi devices to communicate with each other without a wireless access point (access point), in other words, the operation of the Wi-Fi Direct application is similar In the operation of Bluetooth applications, for example, the Wi-Fi Direct application can support file/file sharing, printing, and synchronization between two Wi-Fi devices. However, since the Wi-Fi Direct standard is As recently announced, there are not many Wi-Fi Certified Direct applications available to users.

再者，由于不同的协议对不同的应用可具有不同的优点，因此，人们也许会想利用多种协议来达到相对应的应用的最佳效能。Furthermore, since different protocols have different advantages for different applications, people may want to use multiple protocols to achieve the best performance for corresponding applications.

因此，需要一种可透过一种通信协议(例如，无线兼容认证直连协议)来支持用于另一种通信协议(例如，蓝牙协议)的应用的新颖设计。Therefore, there is a need for a novel design that can support applications for another communication protocol (eg, Bluetooth protocol) through one communication protocol (eg, Wi-Fi Direct).

图1为本发明通信系统的一个实施例的功能方块图。通信系统100包含第一装置102以及第二装置104，上述两装置的其中一个为传输端，而其中的另一个则为接收端，其中该接收端用于接收自该传输端产生的控制信息及数据。对于第一装置102来说，其包含处理器(processor)112、机器可读介质(machinereadable medium)以及多个通信元件(communication device)116_1及116_2，其中机器可读介质耦接于处理器112，且机器可读介质可例如存储系统(storagesystem)114，存储系统114可利用一个或多个内存元件(memory device)来实现，且通信元件116_1及116_2均耦接于处理器112。对于第二装置104来说，其包含处理器122、机器可读介质以及多个通信元件126_1及126_2，其中，机器可读介质耦接于处理器122，且机器可读介质可例如存储系统124，存储系统124可利用一个或多个内存元件来实现，且通信元件126_1及126_2均耦接于处理器122。为使说明能简单明了，第一装置102及第二装置104之中的每一个装置均仅显示了两个设置于其中的通信元件，然而，以上并非用于做为本发明的限制。FIG. 1 is a functional block diagram of an embodiment of the communication system of the present invention. Thecommunication system 100 includes afirst device 102 and asecond device 104, one of the above two devices is a transmitting end, and the other is a receiving end, wherein the receiving end is used for receiving control information generated from the transmitting end and data. For thefirst device 102, it includes a processor (processor) 112, a machine readable medium (machine readable medium) and a plurality of communication elements (communication device) 116_1 and 116_2, wherein the machine readable medium is coupled to theprocessor 112, And the machine-readable medium can be, for example, a storage system (storage system) 114 , thestorage system 114 can be implemented by one or more memory devices (memory device), and the communication devices 116_1 and 116_2 are both coupled to theprocessor 112 . For thesecond device 104, it includes aprocessor 122, a machine-readable medium, and a plurality of communication elements 126_1 and 126_2, wherein the machine-readable medium is coupled to theprocessor 122, and the machine-readable medium can be, for example, astorage system 124 Thestorage system 124 can be implemented by using one or more memory elements, and the communication elements 126_1 and 126_2 are both coupled to theprocessor 122 . To simplify the description, each of thefirst device 102 and thesecond device 104 only shows two communication elements disposed therein, however, the above is not intended to limit the present invention.

由图1可知，存储系统114及124之中的每个存储系统均具有应用软件(application software)APP1/APP2及程序代码(program code)PROG1/PROG2存储于其中。当处理器112/122执行应用软件APP1/APP2时，会使能一个用于通信协议(communication protocol)P1的应用。请注意，通信元件116_1及126_1是透过通信协议P1来传输/接收数据，而通信元件116_2及126_2则是透过不同于通信协议P1的通信协议P2来传输/接收数据。It can be seen from FIG. 1 that each of thestorage systems 114 and 124 has application software (application software) APP1/APP2 and program code (program code) PROG1/PROG2 stored therein. When theprocessor 112/122 executes the application software APP1/APP2, an application for the communication protocol (communication protocol) P1 will be enabled. Please note that the communication elements 116_1 and 126_1 transmit/receive data through the communication protocol P1, while the communication elements 116_2 and 126_2 transmit/receive data through the communication protocol P2 different from the communication protocol P1.

当处理器112/122执行程序代码PROG1/PROG2时，因为处理器112/122也执行应用软件APP1/APP2，故程序代码PROG1/PROG2可用于控制所使能的应用的数据传输及接收，更具体地说，当选择了第一数据处理模式(datatransaction mode)(亦即，常用模式)Mode_1时，用于通信协议P1的该应用的数据传输及接收会通过通信元件116_1/126_1来执行，然而，当选择了第二数据处理模式(亦即，本发明所提出的新模式)Mode_2时，用于通信协议P1的该应用的数据传输及接收会通过通信元件116_2/126_2来执行。When theprocessor 112/122 executes the program code PROG1/PROG2, because theprocessor 112/122 also executes the application software APP1/APP2, the program code PROG1/PROG2 can be used to control the data transmission and reception of the enabled application, more specifically In other words, when the first data transaction mode (datatransaction mode) (that is, the common mode) Mode_1 is selected, the data transmission and reception for the application of the communication protocol P1 will be performed by the communication element 116_1/126_1, however, When the second data processing mode (ie, the new mode proposed by the present invention) Mode_2 is selected, the data transmission and reception for the application of the communication protocol P1 will be performed through the communication element 116_2/126_2.

假定第一装置102作为传输端以及第二装置104作为接收端，处理器112所执行的程序代码PROG1因而可采用本发明所提出的数据传输方法，以控制自同一处理器112所执行的应用软件APP1产生的数据的传输，以及处理器122所执行的程序代码PROG2因而可采用本发明所提出的数据接收方法，以控制自同一处理器122所执行的应用软件APP2产生的数据的接收。进一步的说明详述如下。Assuming that thefirst device 102 is used as the transmitting end and thesecond device 104 is used as the receiving end, the program code PROG1 executed by theprocessor 112 can thus adopt the data transmission method proposed by the present invention to control the application software executed from thesame processor 112 The transmission of data generated by APP1 and the program code PROG2 executed by theprocessor 122 can thus adopt the data receiving method proposed by the present invention to control the receiving of data generated by the application software APP2 executed by thesame processor 122 . Further instructions are detailed below.

请结合图1来参考图2。图2为本发明数据传输方法的一个实施例的流程图。可透过处理器112执行程序代码PROG1来实现该数据传输方法，并可简单归纳如下。Please refer to FIG. 2 in conjunction with FIG. 1 . Fig. 2 is a flowchart of an embodiment of the data transmission method of the present invention. The data transmission method can be implemented by theprocessor 112 executing the program code PROG1, and can be briefly summarized as follows.

步骤200：开始。Step 200: start.

步骤202：检查是否有选择第一数据处理模式(亦即，常用模式)Mode_1？若是，执行步骤210；反之，执行步骤204。Step 202: Check whether the first data processing mode (ie, common mode) Mode_1 is selected? If yes, go tostep 210; otherwise, go tostep 204.

步骤204：接收用于通信协议P1的该应用的数据D1，其中因为处理器112执行应用软件APP1的缘故，该应用会被使能。Step 204: Receive the application data D1 for the communication protocol P1, wherein the application is enabled because theprocessor 112 executes the application software APP1.

步骤206：将对应于通信协议P1的数据D1转换为对应于通信协议P2的数据D2。Step 206: Convert the data D1 corresponding to the communication protocol P1 into data D2 corresponding to the communication protocol P2.

步骤208：将数据D2传递至透过通信协议P2来传输数据D2的通信元件116_2。执行步骤214。Step 208: Transmit the data D2 to the communication element 116_2 that transmits the data D2 through the communication protocol P2. Executestep 214.

步骤210：接收用于通信协议P1的该应用的数据D1，其中因为处理器112执行应用软件APP1的缘故，该应用会被使能。Step 210: Receive the application data D1 for the communication protocol P1, wherein the application is enabled because theprocessor 112 executes the application software APP1.

步骤212：将数据D1传递至透过通信协议P1来传输数据D1的通信元件116_1。执行步骤214。Step 212: Deliver the data D1 to the communication element 116_1 that transmits the data D1 through the communication protocol P1. Executestep 214.

步骤214：结束。Step 214: end.

在步骤202中，处理器112所执行的程序代码PROG1会检查目前所选择的为哪个数据处理模式，举例来说，用户可手动设定数据处理模式。当选择第一交易模式Mode_1时(亦即，并没有选择第二交易模式Mode_2)，其意味着自用于通信协议P1的该应用产生的数据D1，应会透过通信协议P1来从该传输端(亦即，第一装置102)被传输至该接收端(亦即，第二装置104)，因此，数据D1会被传递至通信元件116_1以供后续传输之用(如步骤210及212所示)。在接收到数据D1之后，通信元件116_1会将所接收到的数据D1传输至设置于该接收端的通信元件126_1。Instep 202, the program code PROG1 executed by theprocessor 112 checks which data processing mode is currently selected. For example, the user can manually set the data processing mode. When the first transaction mode Mode_1 is selected (that is, the second transaction mode Mode_2 is not selected), it means that the data D1 generated from the application for the communication protocol P1 should be transmitted from the transmission terminal through the communication protocol P1 (that is, the first device 102) is transmitted to the receiving end (that is, the second device 104), therefore, the data D1 will be delivered to the communication element 116_1 for subsequent transmission (as shown insteps 210 and 212 ). After receiving the data D1, the communication element 116_1 transmits the received data D1 to the communication element 126_1 disposed at the receiving end.

当选择第二交易模式Mode_2时(亦即，并没有选择第一交易模式Mode_1)，其意味着自用于通信协议P1的该应用产生的数据D1，应会透过通信协议P2来从该传输端(亦即，第一装置102)被传输至该接收端(亦即，第二装置104)。由于通信协议P1及通信协议P2两者之间会存在差异，对应于通信协议P1的数据D1会被转换为对应于通信协议P2的数据D2(如步骤204及206所示)，接下来，数据D2会被传递至通信元件116_2以供后续传输之用(如步骤208所示)。请注意，在通信元件116_2及通信元件126_2在建立彼此之间连结(link)的交握程序(hand-shaking procedure)的期间，通信元件116_2及通信元件126_2会分别记录(register)(从数据D1获得)对数据D2进行交易的特定服务。在接收到数据D2之后，通信元件116_2会将所接收到的数据D2传输至设置于该接收端的通信元件126_2。When the second transaction mode Mode_2 is selected (that is, the first transaction mode Mode_1 is not selected), it means that the data D1 generated from the application for the communication protocol P1 should be transmitted from the transmission terminal through the communication protocol P2 (ie, the first device 102 ) is transmitted to the receiving end (ie, the second device 104 ). Since there will be differences between the communication protocol P1 and the communication protocol P2, the data D1 corresponding to the communication protocol P1 will be converted into the data D2 corresponding to the communication protocol P2 (as shown insteps 204 and 206), and then the data D2 will be delivered to the communication element 116_2 for subsequent transmission (as shown in step 208 ). Please note that during the hand-shaking procedure (hand-shaking procedure) between the communication element 116_2 and the communication element 126_2, the communication element 116_2 and the communication element 126_2 will respectively record (register) (from the data D1 Obtain) specific services for transactions on data D2. After receiving the data D2, the communication element 116_2 transmits the received data D2 to the communication element 126_2 disposed at the receiving end.

在此实施例中，除了将数据D2传输至通信元件126_2之外，通信元件116_2用于控制在该传输端与该接收端之间数据D2的传输，例如，建立第一装置102与第二装置104之间需要的连结，换言之，通信协议P1并不会控制数据D2的传输，因此，在传输数据D2的期间，可停用或关闭通信元件116_1，也就是说，当选择第二数据处理模式Mode_2时，可允许停用或关闭通信元件116_1。In this embodiment, in addition to transmitting the data D2 to the communication element 126_2, the communication element 116_2 is used to control the transmission of the data D2 between the transmitting end and the receiving end, for example, establishing thefirst device 102 and thesecond device 104, in other words, the communication protocol P1 does not control the transmission of the data D2, therefore, during the transmission of the data D2, the communication element 116_1 can be disabled or closed, that is, when the second data processing mode is selected In Mode_2, the communication element 116_1 may be disabled or turned off.

在另一实施例中，本发明提供一种数据传输装置，包括：接收模块，用于第一通信协议的应用的第一数据；转换模块，用于将该第一数据转换为对应于第二通信协议的第二数据，其中该第二通信协议不同于该第一通信协议；以及传输模块，用于将该第二数据传递至通信元件，其中该通信元件是用于透过该第二通信协议来传输该第二数据，以及该第一通信协议并不会控制该第二数据的传输。In another embodiment, the present invention provides a data transmission device, including: a receiving module, used for the first data of the application of the first communication protocol; second data of a communication protocol, wherein the second communication protocol is different from the first communication protocol; and a transmission module, configured to transfer the second data to a communication element, wherein the communication element is used to communicate through the second protocol to transmit the second data, and the first communication protocol does not control the transmission of the second data.

请结合图1来参考图3，图3为本发明数据接收方法的一个实施例的流程图。可透过处理器122执行程序代码PROG2来实现该数据接收方法，并可简单归纳如下。Please refer to FIG. 3 in conjunction with FIG. 1 . FIG. 3 is a flow chart of an embodiment of the data receiving method of the present invention. The data receiving method can be implemented by theprocessor 122 executing the program code PROG2, and can be briefly summarized as follows.

步骤300：开始。Step 300: start.

步骤302：检查是否有选择第一数据处理模式(亦即，常用模式)Mode_1？若是，执行步骤310；反之，执行步骤304。Step 302: Check whether the first data processing mode (ie, common mode) Mode_1 is selected? If yes, go to step 310; otherwise, go to step 304.

步骤304：自通信元件126_2取得数据D2，其中通信元件126_2透过通信协议P2来接收数据D2。Step 304: Get the data D2 from the communication element 126_2, wherein the communication element 126_2 receives the data D2 through the communication protocol P2.

步骤306：将对应于通信协议P2的数据D2转换为对应于通信协议P1的数据D1。Step 306: Convert the data D2 corresponding to the communication protocol P2 into data D1 corresponding to the communication protocol P1.

步骤308：发送数据D1至用于通信协议P1的该应用，其中因为处理器122执行应用软件APP2的缘故，该应用会被使能。执行步骤314。Step 308: Send the data D1 to the application for the communication protocol P1, wherein the application is enabled because theprocessor 122 executes the application software APP2. Executestep 314 .

步骤310：自通信元件126_1取得数据D1，其中通信元件126_1透过通信协议P1来接收数据D1。Step 310: Get the data D1 from the communication element 126_1, wherein the communication element 126_1 receives the data D1 through the communication protocol P1.

步骤312：发送数据D1至用于通信协议P1的该应用，其中因为处理器122执行应用软件APP2的缘故，该应用会被使能。执行步骤314。Step 312: Send the data D1 to the application for the communication protocol P1, wherein the application is enabled because theprocessor 122 executes the application software APP2. Executestep 314 .

步骤314：结束。Step 314: end.

在步骤302中，处理器122所执行的程序代码PROG2会检查目前所选择的为哪个数据处理模式，举例来说，用户可手动设定数据处理模式。当选择第一交易模式Mode_1时(亦即，并没有选择第二交易模式Mode_2)，其意味着要被提供至该接收端的用于通信协议P1的应用的数据，应会透过通信协议P1而从该传输端(亦即，第一装置102)被接收，因此，将从通信元件126_1获得的数据D1发送至用于通信协议P1的该应用(步骤310及312)。Instep 302, the program code PROG2 executed by theprocessor 122 checks which data processing mode is currently selected. For example, the user can manually set the data processing mode. When the first transaction mode Mode_1 is selected (that is, the second transaction mode Mode_2 is not selected), it means that the data for the application of the communication protocol P1 to be provided to the receiving end should be transmitted through the communication protocol P1 Received from the transmitting end (ie, the first device 102 ), therefore, the data D1 obtained from the communication element 126_1 is sent to the application for the communication protocol P1 (steps 310 and 312 ).

当选择第二交易模式Mode_2时(亦即，并没有选择第一交易模式Mode_1)，其意味着要被提供至该接收端的用于通信协议P1的应用的数据，应会透过通信协议P2而从该传输端(亦即，第一装置102)被接收，请注意，在通信元件116_2及通信元件126_2在建立彼此之间连结的交握程序的期间，通信元件116_2及通信元件126_2可分别记录(从数据D1获得)对数据D2进行交易的特定服务，因此，在接收到数据D2之后，该接收端(亦即，第二装置104)可轻易地得知透过通信协议P2所传输的数据D2是提供给用于通信协议P1的该应用。由于通信协议P1及通信协议P2两者之间会存在差异，从通信元件126_2获得的数据D2会被转换为对应于通信协议P1的数据D1(如步骤304及306所示)，接下来，将数据D1发送至用于通信协议P1的该应用(步骤308)。在此实施例中，除了接收数据D2之外，通信元件126_2用于控制在该传输端与该接收端之间数据D2的接收，例如，建立第一装置102与第二装置104之间需要的连结，换言之，通信协议P1并不会控制数据D2的接收，因此，在接收数据D2的期间，可停用或关闭通信元件126_1，也就是说，当选择第二数据处理模式Mode_2时，可允许停用或关闭通信元件126_1。When the second transaction mode Mode_2 is selected (that is, the first transaction mode Mode_1 is not selected), it means that the data for the application of the communication protocol P1 to be provided to the receiving end should be transmitted through the communication protocol P2 Received from the transmitting end (i.e., the first device 102), please note that during the handshake procedure between the communication element 116_2 and the communication element 126_2 to establish a connection between each other, the communication element 116_2 and the communication element 126_2 can respectively record (Obtained from data D1) Specific services for transactions on data D2, therefore, after receiving data D2, the receiving end (ie, the second device 104) can easily know the data transmitted through the communication protocol P2 D2 is provided to the application for communication protocol P1. Since there will be differences between the communication protocol P1 and the communication protocol P2, the data D2 obtained from the communication element 126_2 will be converted into data D1 corresponding to the communication protocol P1 (as shown insteps 304 and 306), and then, the Data D1 is sent to the application for communication protocol P1 (step 308). In this embodiment, in addition to receiving the data D2, the communication element 126_2 is used to control the reception of the data D2 between the transmitting end and the receiving end, for example, establishing the required communication between thefirst device 102 and thesecond device 104. In other words, the communication protocol P1 does not control the reception of the data D2, therefore, during the period of receiving the data D2, the communication element 126_1 can be deactivated or closed, that is, when the second data processing mode Mode_2 is selected, it can allow The communication element 126_1 is deactivated or turned off.

上述的通信协议P1及P2之中的每个通信协议均可为任何的有线或无线通信协议。在一个设计实例中，通信协议P1可为无线通信协议(例如，蓝牙协议)，以及另一个通信协议P2可为无线兼容认证协议或无线相容认证直连协议。在另一个设计实例中，通信协议P1可为蓝牙协议，以及另一个通信协议P2可为通用串行总线(universal serial bus，USB)协议或串行端口(serial-port)协议。如上所述，由于蓝牙技术已经过了长时间的发展，已提出了用于蓝牙协议的多种不同应用，因此，通过传输端采用本发明所提出的数据传输方法以及接收端采用本发明所提出的数据接收方法，可轻易地将蓝牙应用的应用层面拓展至其他具有几乎无支持的应用的通信协议。再者，在通信协议P2为无线通信协议(例如，无线兼容认证协议/无线兼容认证直连协议)，以及其所支持的最大无线传输距离(maximum wireless transmission distance)长于蓝牙协议所支持的最大无线传输距离的情形下，蓝牙应用的服务范围会因而增加。再者，在通信协议P2为无线通信协议(例如，无线兼容认证协议/无线兼容认证直连协议)，以及其所支持的最大数据传输速率(maximum data transfer rate)高于蓝牙协议所支持的最大数据传输速率的情形下，蓝牙应用的吞吐量(throughput)会因而增加。Each of the aforementioned communication protocols P1 and P2 may be any wired or wireless communication protocol. In one design example, the communication protocol P1 may be a wireless communication protocol (eg, Bluetooth protocol), and the other communication protocol P2 may be a wireless compatible authentication protocol or a wireless compatible authentication direct connection protocol. In another design example, the communication protocol P1 may be a Bluetooth protocol, and another communication protocol P2 may be a universal serial bus (universal serial bus, USB) protocol or a serial-port protocol. As mentioned above, since the bluetooth technology has been developed for a long time, many different applications for the bluetooth protocol have been proposed. The data receiving method of the Bluetooth application can easily extend the application level of the Bluetooth application to other communication protocols with almost no supported applications. Furthermore, the communication protocol P2 is a wireless communication protocol (for example, a wireless compatible authentication protocol/a wireless compatible authentication direct connection protocol), and the maximum wireless transmission distance (maximum wireless transmission distance) supported by it is longer than the maximum wireless transmission distance supported by the Bluetooth protocol. In the case of transmission distance, the service range of Bluetooth applications will thus increase. Furthermore, when the communication protocol P2 is a wireless communication protocol (for example, wireless compatible authentication protocol/wireless compatible authentication direct connection protocol), and the maximum data transfer rate (maximum data transfer rate) supported by it is higher than the maximum supported by the Bluetooth protocol. In the case of lower data transfer rates, the throughput of Bluetooth applications will thus increase.
