技术领域technical field

There are many types of products, such as personal computers, mobile phones, printers and even digital Home appliance.

其中，数字化的家电产品更是近来的热门话题。为了实现真正的数字化家电控制，家电产品需要能与中央控制器或其他电子装置进行通讯，以交换目前的开关状态与运作情报。Among them, digital home appliances are a hot topic recently. In order to achieve real digital home appliance control, home appliances need to be able to communicate with a central controller or other electronic devices to exchange current switch status and operational information.

在一般电脑装置间通常采用无线通讯协定(例如Wifi通讯协定)进行通讯，但对家电而言，最普及的传输线路无疑是电力布线，因此，业界已积极开发各种电力线网络(power line network)的产品应用，让家电或其他电子装置在接上电源插座时即可便利的连接电力线网络。Wireless communication protocols (such as Wifi communication protocol) are usually used for communication between general computer devices, but for home appliances, the most popular transmission line is undoubtedly power wiring. Therefore, the industry has actively developed various power line networks. The application of the product allows home appliances or other electronic devices to be easily connected to the power line network when they are connected to the power outlet.

然而，实际应用情况下，电力线网络虽可遍及各个角落，但其网络传输品质却容易受到各种因素影响，例如，当多个电子装置同时利用电力线网络传输数据时，可能导致频宽不足及传输速度下降；另一方面，若特定电子装置运作时消耗大量电力(如冰箱降温、电磁炉启动时)，可能在特定电力线节点上造成明显的信号噪音干扰，使通讯品质下降甚至中断。However, in practical applications, although the power line network can be used everywhere, its network transmission quality is easily affected by various factors. For example, when multiple electronic devices transmit data through the power line network at the same time, it may cause insufficient bandwidth and transmission On the other hand, if a specific electronic device consumes a large amount of power during operation (such as when the refrigerator cools down or the induction cooker is started), it may cause obvious signal noise interference on a specific power line node, degrading or even interrupting the communication quality.

Take points. Regarding the packet receiving and delivery method between theaccess points 120, the present invention further provides a network communication method, which can be used in conjunction with thenetwork communication framework 100 in the above embodiment, and the network communication method is described in detail as follows .

请一并参阅图5以及图6，图5绘示前述实施例中任一个存取点120(120a、120b或120c)接收信息封包时网络通讯方法的流程图；图6绘示前述实施例中任一个存取点120(120a、120b或120c)欲传送信息封包时网络通讯方法的流程图。Please refer to FIG. 5 and FIG. 6 together. FIG. 5 shows a flow chart of the network communication method when any one of the access points 120 (120a, 120b or 120c) in the foregoing embodiment receives an information packet; A flow chart of the network communication method when any one of the access points 120 (120a, 120b or 120c) intends to transmit information packets.

如图5所示的信息封包接收流程中，当任一个存取点120接收信息封包后，首先执行步骤S500，判断该信息封包的一目的装置是否指向该存取点本身，若为是，则执行步骤S502，由存取点120本身处理信息封包，例如，读取信息封包内容并执行相关设定或操作，例如更新存取点120内的设定或网络位置对照表等。In the information packet receiving process shown in Figure 5, after anyaccess point 120 receives the information packet, first execute step S500 to judge whether a destination device of the information packet points to the access point itself, if yes, then Step S502 is executed to process the information packet by theAP 120 itself, for example, read the content of the information packet and perform related settings or operations, such as updating the settings in theAP 120 or the network location comparison table.

若步骤S500结果为非指向为存取点120本身，则执行步骤S504，判断信息封包是否来自外部网际网络200。If the result of step S500 is not pointing to theaccess point 120 itself, then execute step S504 to determine whether the information packet comes from theexternal Internet 200 .

当步骤S504判断该信息封包非来自外部网际网络200时，执行步骤S506判断该信息封包是否来自电力线网络140。若步骤S506判断信息封包来自电力线网络140，执行步骤S508将该信息封包传送至外部网际网络200，另一方面，若步骤S506判断信息封包非来自电力线网络140时，则对信息封包进行传送程序，即步骤S510。其中，关于传送程序步骤S510的细节内容，可在后续段落及图6中传送信息封包的流程中得到详细说明。When step S504 determines that the information packet is not from theexternal Internet 200 , step S506 is executed to determine whether the information packet is from thepower line network 140 . If step S506 judges that the information packet is from thepower line network 140, execute step S508 to transmit the information packet to theexternal Internet 200; Namely step S510. Wherein, the details of the sending procedure step S510 can be described in detail in the subsequent paragraphs and the flow of sending the information packet in FIG. 6 .

若步骤S504结果为信息封包来自外部网际网络200，则执行步骤S512，判断信息封包的目的装置是否指向所有存取点(120a、120b、120c)所对应的所有用户端装置(160～168)中任一者，或是任何一个存取点(120a、120b、120c)本身。若步骤S512判断信息封包的目的装置未指向多个用户端装置160～168中任一者，且未指向任何一个存取点120a～120b，表示此信息封包可能为与网络通讯架构100无关的垃圾封包或恶意封包，则执行步骤S514舍弃此信息封包。If the result of step S504 is that the information packet comes from theexternal Internet 200, then step S512 is executed to determine whether the destination device of the information packet points to all client devices (160-168) corresponding to all access points (120a, 120b, 120c) Either, or any one of the access points (120a, 120b, 120c) itself. If it is determined in step S512 that the destination device of the information packet is not directed to any one of the plurality of client devices 160-168, and is not directed to any of theaccess points 120a-120b, it means that the information packet may be garbage that has nothing to do with thenetwork communication framework 100. packet or malicious packet, execute step S514 to discard the information packet.

步骤S512判断信息封包的目的装置指向网络通讯架构100内部网络的范围内(即任一用户端装置160～168或是任一存取点120a～120c)，则执行步骤S516，判断信息封包的目的装置是否指向该存取点120其子区域网络LAN3内的用户端装置。请一并参考图4B，例如，以存取点120a而言，则判断信息封包的目的装置是否指向存取点120a其子区域网络LAN3a内的用户端装置160；以存取点120b而言，则判断信息封包的目的装置是否指向存取点120b其子区域网络LAN3b内的用户端装置162、164，以此类推。Step S512 judges that the destination device of the information packet points to the range of the internal network of the network communication framework 100 (that is, any client device 160-168 or anyaccess point 120a-120c), then executes step S516 to determine the purpose of the information packet Whether the device points to the client device in the sub-area network LAN3 of theaccess point 120 . Please refer to FIG. 4B together. For example, in terms ofaccess point 120a, it is determined whether the destination device of the information packet points to theclient device 160 in the sub-area network LAN3a of theaccess point 120a; in terms ofaccess point 120b, Then it is judged whether the destination device of the information packet points to theclient devices 162 and 164 in the sub-area network LAN3b of theaccess point 120b, and so on.

若步骤S516判断为是，则执行步骤S518，通过该子区域网络LAN3传送信息封包至用户端装置。If the determination in step S516 is yes, then step S518 is executed to transmit the information packet to the client device through the sub-area network LAN3.

若步骤S516判断结果为非子区域网络内，则进一步执行步骤S520至步骤S524，进而判断电力线网络140的网络品质，并据以选择性地将该信息封包通过第一区域网络LAN1或第二区域网络LAN2传送至其他存取点。If the judgment result of step S516 is not in the sub-area network, further execute steps S520 to S524, and then judge the network quality of thepower line network 140, and accordingly selectively pass the information packet through the first local area network LAN1 or the second area Network LAN2 transmits to other access points.

于此实施例中，步骤S520可检测电力线网络140的整体传输速率，并判断电力线网络140(第一区域网络LAN1)的整体传输速率是否大于基准速率，例如判断基准可为频宽是否大于5MB/sec。In this embodiment, step S520 can detect the overall transmission rate of thepower line network 140, and determine whether the overall transmission rate of the power line network 140 (first local area network LAN1) is greater than the reference rate, for example, the determination criterion can be whether the bandwidth is greater than 5MB/ sec.

若电力线网络140的整体传输速率大于该基准速率，则执行步骤S522将该信息封包通过该第一区域网络LAN1传送至其他存取点。反之，若该整体传输速率未达该基准速率，则执行步骤S524将信息封包通过该第二区域网络LAN2传送至其他存取点。If the overall transmission rate of thepower line network 140 is greater than the reference rate, execute step S522 to transmit the information packet to other access points through the first local area network LAN1. On the contrary, if the overall transmission rate does not reach the reference rate, execute step S524 to transmit the information packet to other access points through the second local area network LAN2.

接着请一并参见图6，其绘示任一个存取点120(120a、120b或120c)欲传送信息封包或是前述步骤S510中的传送程序所采用的流程内容。Next, please refer to FIG. 6 , which shows the process content used by any one of the access points 120 ( 120 a , 120 b or 120 c ) to transmit the information packet or the transmission procedure in the aforementioned step S510 .

如图所示，当任一个存取点120上产生欲传送的信息封包时，网络通讯方法执行步骤S600，判断信息封包的目的装置是否指向存取点120的子区域网络LAN3内的用户端装置。若步骤S600判断为是，则执行步骤S602，透过子区域网络LAN3传送信息封包至用户端装置。As shown in the figure, when an information packet to be transmitted is generated on anyaccess point 120, the network communication method executes step S600 to determine whether the destination device of the information packet points to the client device in the sub-area network LAN3 of theaccess point 120. . If the determination in step S600 is yes, execute step S602 to send the information packet to the client device through the sub-area network LAN3.

若步骤S600判断结果为非指向子区域网络内，则执行步骤S604判断该信息封包是否指向该外部网际网络200。If the determination result of step S600 is that it is not directed to the sub-area network, then execute step S604 to determine whether the information packet is directed to theexternal Internet 200 .

若步骤S604结果为信息封包非指向该外部网际网络200，则执行步骤S606通过第二区域网络LAN2传送信息封包至其他存取点。If the result of step S604 is that the information packet is not directed to theexternal Internet 200, then execute step S606 to transmit the information packet to other access points through the second local area network LAN2.

若步骤S604结果为信息封包指向外部网际网络200，则执行步骤S608判断目前存取点是否连接至外部网际网络200。If the result of step S604 is that the information packet is directed to theexternal Internet 200 , then step S608 is executed to determine whether the current access point is connected to theexternal Internet 200 .

若步骤S608判断为是，则执行步骤S610传送信息封包至外部网际网络200。另一方面，若步骤S608判断结果为此一存取点120本身未连接至外部网际网络200，则执行步骤S612判断电力线网络140的整体传输速率是否大于基准速率(或判断电力线网络140的网络品质)，并据以选择性地将该信息封包通过该第一区域网络或该第二区域网络传送至其他存取点。If the determination in step S608 is yes, execute step S610 to transmit the information packet to theexternal Internet 200 . On the other hand, if the judgment result of step S608 is that theaccess point 120 itself is not connected to theexternal Internet 200, then execute step S612 to judge whether the overall transmission rate of thepower line network 140 is greater than the reference rate (or judge the network quality of the power line network 140 ), and accordingly selectively transmit the information packet to other access points through the first local area network or the second local area network.

若电力线网络140的整体传输速率大于基准速率，则执行步骤S614将信息封包通过第一区域网络LAN1传送至其他存取点。反之，若整体传输速率未达基准速率，则执行步骤S606将信息封包透过第二区域网络LAN2传送至其他存取点。If the overall transmission rate of thepower line network 140 is greater than the reference rate, step S614 is executed to transmit the information packet to other access points through the first local area network LAN1. On the contrary, if the overall transmission rate does not reach the reference rate, execute step S606 to transmit the information packet to other access points through the second local area network LAN2.
