Description

和无线通信装置技术领域本发明涉及无线通信系统和无线通信装置,更具体而言,本发明涉及如下的无线通信系统和无线通信装置,其特征在于在自组织(ad-hoc)网络中从休眠状态返回活动状态的方法。 And a wireless communication apparatus Technical Field The present invention relates to a wireless communication system and wireless communication devices, and more particularly, the present invention relates to a wireless communication apparatus and a wireless communication system, wherein from sleep in the ad-hoc (ad-hoc) networks state method that returns active. 背暈技术目前,用于实现高速无线个人局域网(PAN)的标准规范被定义在IEEE 802.15.3中,并被公认为高速无线通信系统之一。 Halo Art back, for high-speed wireless personal area network (PAN) is a standard specification defined in the IEEE 802.15.3, and is recognized as one of high-speed wireless communication system. 例如,国际公布WO 2004/071020的小册子定义了一种这样的方法,利用该方法,在省电模式时,在多个超级帧周期中执行一次激活,并且除控制台(PNC)之外的其他无线通信装置(终端)按照需要在两种操作状态(即休眠状态和活动状态)之间切换,从而实现低功耗操作。 For example, International Publication WO 2004/071020 brochure defines one such method, with this method, in the power saving mode, performs a plurality of super-frames in the activation period, and in addition to the console (the PNC) of other wireless communication apparatus (terminal) needs between the two operational states (i.e., a sleep state and an active state) in accordance with such low power operation. 就是说,定义了一种这样的方法,利用该方法,以低功耗工作的无线通信装置在几个超级帧中一直处于休眠状态,然后只在一个超级帧中转换到活动状态,从而在该时刻与控制台和其他无线通信装置交换数据。 That is, such a method is defined, with this method, a wireless communication device operating with low power consumption that remain dormant in the super-frame number, and only converted at a super-frame to an active state, so that the time and the console and other wireless communication devices to exchange data. 就是说,由于未进入休眠状态的控制台以固定时间间隔接收信标信号,因此相邻的无线通信装置(终端)与信标信号同步地执行通信。 That is, since the console does not enter a sleep state to receive a beacon signal of a fixed time interval, thus the adjacent wireless communication apparatus (terminal) performs communication with the beacon signal in synchronization. 根据本发明的受让人所拥有的日本早期公开专利申请No. 2002-64501,公开了一种这样的技术:处于省电模式的无线通信装置将有关存在于网络中的其他无线通信装置的出现告知控制台。 According to Japanese Laid-Open Patent is owned by the assignee of the present invention Application No. 2002-64501, discloses one such technique: a wireless communication apparatus in the power saving mode will appear in the network of other wireless communication devices relating to the presence of inform console. 在该技术中,示出了一种无线通信方法,该方法通过设置两个周期,即用于接收的第一周期和用于发送的第二周期,在发送激活周期内将关于在接收激活周期内识别出的终端站的操作状态告知控制台。 In this technique, there is shown a wireless communication method by providing two cycles, i.e. for a first period and a second period for receiving the transmission, in the transmission cycle activated in the receiving activation cycle on the identified operation state of the terminal stations to inform the console. 此外,近些年,已经开发出如下方法:在无需控制台的情况下,相邻的无线通信装置以自治的分布式方式工作,并构成自组织网络。 Further, in recent years, a method has been developed: the console without the need for adjacent the wireless communication device operates in an autonomous distributed manner, and constitute a self-organizing network. 有利的构不需要选择控制台的过程,并且简化了进入网络的处理。 Advantageously the selection process does not require the configuration of the console, and simplifies the process of entering the network. 在这种情况下,由于没有控制台,因此难以定义在上述IEEE 802.15.3 中定义的省电模式;但是,类似的低功耗操作被定义为"冬眠模式"。 In this case, since the console, it is difficult to define the power saving mode defined in the IEEE 802.15.3 above; however, a similar operation is defined as a low power consumption "hibernation mode." 发明内容在自组织网络中,已经存在如下问题:虽然每个无线通信装置发送信标信号,但是无线通信装置无法依赖于处于冬眠模式的无线通信装置的信标发送位置,通过参考其它无线通信装置的信标信号来准确获知它自己的信标发送位置。 SUMMARY OF THE INVENTION In the ad-hoc network, has the following problems: Although each wireless communication device transmits a beacon signal, the wireless communication device can not depend on the beacon transmission position of the radio communication apparatus is in hibernation mode, by reference to other wireless communication devices beacon signals to accurately know its own beacon transmission position. 此外,根据在日本早期公开专利申请No. 2002-64501中描述的传输控制方法,处于省电模式(也被称为休眠模式)的无线通信装置需要设置两个周期,其中的第一周期用于接收,第二周期用于发送;因此,无线通信装置无法在没有来自控制台的用于设置的指令或请求的情况下进行操作。 Further, the radio communication apparatus in Japanese Laid-Open Patent Application No. 2002-64501 described transmission control method, the power saving mode (also called a sleep mode) according to the need to set two cycles, wherein the first period for receiving, for transmitting a second cycle; therefore, the radio communication apparatus can not operate in the absence of instructions from a console for setting or request. 在已有的具有控制台的通信系统中,处于省电模式的终端站已经实现了与来自一直发送信号的控制台的信号之间的同步。 In the conventional communication system having a console, a terminal station is in the power saving mode has been achieved between the synchronization signal has been transmitted from the console signal. 但是,在自组织网络中,存在如下问题:每个通信站由于没有控制台而无法进入省电模式,它无法指定与哪个通信站实现同步。 However, in an ad hoc network, there is a problem: because there is no console each communication station can not enter power-saving mode, it can not specify which synchronized with the communication station. 此外,在自组织网络中,存在如下问题:由于在相邻无线通信装置之间的每个同步都被实现用于通信,因此无线通信装置无法指定它自己的信标信号的发送时刻,除非该无线通信装置从相邻的无线通信装置接收到特定信标信号0此外,存在如下问题:无线通信装置无法获知它自己的信标信号的发送位置,除非该无线通信装置在它自己的发送信标信号位置之前接收到来自相邻无线通信装置的信标信号。 Further, in the ad hoc network, there is a problem: Since each synchronization can be implemented for communication between the neighboring wireless communication devices, the radio communication apparatus thus can not specify the transmission time of its own beacon signal, unless the the wireless communication apparatus receives from the adjacent wireless communication device to a specific beacon signal 0 in addition, there is a problem: a wireless communication apparatus can not know the position of its own transmitted beacon signal, transmits its own beacon unless the wireless communication device beacon signals from neighboring radio communication apparatus before a signal is received from the position. 此外,存在如下问题:在信标信号的发送位置被安排在超级帧周期的头部的无线通信系统中,无线通信装置无法在处于冬眠模式的无线通信装置进入活动状态之后立即获知相邻无线通信装置的出现。 Informed immediately after the neighboring wireless communication beacon transmission position signal is arranged at the head of the super frame period in a wireless communication system, a wireless communication device can not enter an active state in a wireless communication apparatus is in hibernation mode: Moreover, there is a problem appearance of the device. 此外,存在如下问题:由于在无线通信装置从休眠状态转换到活动状态之后,该无线通信装置尚未接收到来自相邻无线通信装置的信标信号,法使用发送信标信号来交换相邻无线通信装置的出现和操作状态。 Further, there is a problem: since the wireless communication apparatus after the transition from the sleep state to the active state, the wireless communication apparatus has not received the beacon signal from a neighboring wireless communication device, a wireless communication method using a transmission beacon signal exchanging adjacent and the operating state of the device occurs. 本发明是针对已有无线通信系统和无线通信装置具有的前述问题而做出的,并且希望提供自组织网络中的新型且改良的无线通信系统和无线通信装置,它能够在从休眠状态转换到活动状态时指定准确的信标信号的发送位置。 The present invention is directed to the aforementioned problems of the prior radio communication system and the wireless communication device has been made, and is desirable to provide novel and improved wireless communication system and a wireless communication apparatus in an ad hoc network, it is possible to transition from a sleep state specify the exact time of the beacon signal transmitted active position. 此外,希望提供新型且改良的无线通信系统和无线通信装置,它能够在处于冬眠模式的无线通信装置从休眠状态转换到活动状态时发送准确的信标信号,该信标信号包括相邻无线通信装置的出现。 Further, it is desirable to provide novel and improved wireless communication system and a wireless communication device, it can switch to the sleep state from the radio communication apparatus is in hibernation mode active state accurately transmitted beacon signal, the beacon signal comprising an adjacent wireless communication appearance of the device. 根据本发明的实施例,提供了一种包括多个构成自组织网络的无线通信装置的无线通信系统。 According to an embodiment of the present invention, there is provided a wireless communication system comprising a plurality of wireless communication devices constituting the ad-hoc network. 在根据本发明实施例的无线通信系统中,每个无线通信装置的每个超级帧的操作状态被确定来自以下三种操作状态:活动状态,在该状态中,按照需要执行信标信号的发送/接收和数据的发送/接收;休眠状态,在该状态中,不执行信标信号的发送/接收和数据的发送/ 接收;以及预接收状态,在该状态中,信标信号被接收,并且随后不执行信标信号的发送和数据的发送。 In a wireless communication system according to an embodiment of the present invention, the operating status of each super-frame of each wireless communication device is determined from the following three operating states: an active state, in this state, it needs to be performed according to a beacon signal transmitted / reception and data transmission / reception; sleep state, in this state, does not transmit the transmission / reception and data beacon / reception of signals; and a pre-reception state, in this state, the beacon signal is received, and then sends a beacon signal and the data transmission is not performed. 此外,还可以定义如下的预接收状态,在该状态中,信标信号被接收,并且随后不执行信标信号的发送/接收和数据的发送/接收。 In addition, the following may also be pre-defined reception state, in this state, the beacon signal is received, and then does not transmit the transmission / reception data and beacon signals / reception. 可替换地,无线通信装置在预定的超级帧周期中从休眠状态转换到预接收状态,并从相邻的无线通信装置接收信标信号,并且在根据包含在信标信号中的信息转换到活动状态时,根据信标信号的接收时刻,无线通信装置设置信标信号的发送时刻(实现同步)。 Alternatively, the wireless communication apparatus at a predetermined conversion of the super frame period from a receiving state to the pre-dormant state, and from an adjacent wireless communication apparatus receives the beacon signal, and the conversion activity according to the information contained in the beacon signal state, based on the reception timing of the beacon signal, the wireless communication apparatus transmits a beacon signal is provided in time (synchronized). 对于所描述的无线通信系统,在自组织网络中,无线通信装置在预定的超级帧周期中从休眠状态转换到预接收状态,从而可以从相邻的无线通信装置接收信标信号(这种操作模式被称为"低功耗模式"或"冬眠模式")。 For the described wireless communication system, in an ad hoc network, the wireless communication apparatus at a predetermined conversion of the super frame period from a receiving state to the pre-dormant state, so that may be adjacent to the radio communication apparatus receives a beacon signal (this operation mode is referred to as "low power mode" or "hibernation mode"). 此外,在根据包含在信标信号中的信息转换到活动状态时,无线通信装置提前接收来自相邻无线通信装置的信标,从而可以获知它自己的信标信号的发送时刻。 Further, when switching to the active state based on the information contained in the beacon signal, the wireless communication apparatus receives the beacon from an adjacent early radio communication apparatus, which can know its own transmission timing of the beacon signal. 此外,在从休眠状态转换到活动状态时,通过接收来自相邻无线通信装置的信标信号,无线通信装置可以获知相邻无线通信装置的出现和相邻无线通信装置的操作状态,并在活动状态中,在它自己的信标信号中描述准确的信息。 Further, when transitioning from a sleep state to an active state by receiving a beacon signal from an adjacent wireless communications apparatus, the wireless communication apparatus can learn the operating state occurs and the radio communication apparatus adjacent a neighboring wireless communication devices, and activities state, described accurate information in its own beacon signal. 可替换地,在上述无线通信系统中,当在预接收状态中由无线通信装置接收到的信标信号包含关于被寻址到其上的激活请求的信息的情况下, 无线通信装置转换到活动状态。 Alternatively, in the wireless communication system, a case where the radio communication received by the receiving means in the pre-state, a beacon signal includes an active addressed to it on the request information, the wireless communication means to the activity status. 从而,在从休眠状态转换到活动状态时, 无线通信装置可以有足够时间被激活。 Therefore, when transitioning from a sleep state to an active state, the wireless communication device can have enough time to be activated. 一般而言,为了在从休眠状态转换到活动状态的过程中激活软件部分,需要有足够时间(例如几百毫秒)。 Generally, in order to activate the software portion of the transition from the sleep state to the active state of the process, the need for sufficient time (e.g., several hundred milliseconds). 在过去,在信标信号之间的时间间隔(例如大约40毫秒到60毫秒)期间,不能发送任何数据,从而导致系统质量下降。 During the past, the time interval between the beacon signals (e.g., from about 40 milliseconds to 60 milliseconds) and can not transmit any data, thereby resulting in decreased quality of the system. 根据本发明的实施例, 定义了预接收状态,在该状态中,无线通信装置接收信标信号,但随后不执行信标信号发送和数据发送。 According to an embodiment of the present invention, the pre-defined reception state, in this state, the radio communication apparatus receives the beacon signal, but then does not transmit the beacon signal transmission and execution data. 因此,处于预接收状态的无线通信装置可以激活软件部分,同时从本质上保持硬件部分处于休眠状态。 Thus, the radio communication apparatus in a pre-reception state may activate the software part, while keeping the hardware part is essentially in a sleep state. 可替换地,在转换到活动状态时,无线通信装置从在预接收状态中接收到的信标信号中获知存在于相邻区域中的另一无线通信装置的状态,并且宣告它自己的关于转换到活动状态的发送信标信息。 Alternatively, when switching to the active state, the state of the wireless communication device is known another wireless communication device is present in the adjacent region from the pre-received in the beacon reception state signal, and the conversion on its own declared transmitting the beacon information to the active state. 从而,在预接收状态中接收到的信标信号中包含的信息可以被反映在无线通信装置在下一超级帧中发送的信标信号中包含的信息中。 Accordingly, the information received in the pre-reception state of the beacon signal may be reflected comprising information included in the radio communication apparatus beacon signal transmitted in the next super-frame in the. 可替换地,每个构成自组织网络的无线通信装置将关于相邻无线通信装置中处于低功耗模式的无线通信装置的出现的信息添加到信标信号并宣告该信息。 Alternatively, each wireless communication apparatus constituting the self-organizing network will appear to add information about the radio communication apparatus in a wireless communication device in a low power mode of an adjacent beacon signal and the announcement information. 低功耗模式指的是如下模式,在该模式中,处于休眠状态的无线通信装置在预定的超级帧周期中转换到预接收状态或活动状态。 Low power mode refers to a mode, in this mode, the radio communication apparatus in a sleep state transitions to a pre-reception state or an active state in a predetermined superframe period. 对于所述结构,即使存在处于低功耗模式的无线通信装置,也可以避免信标信号的冲突。 For the structure, even if the wireless communication apparatus is present in low power mode, the conflict can be avoided beacon signal. 此外,在新加入自组织网络的无线通信装置的情况下,应用相同方式。 Further, in a case where the wireless communication device newly joins the ad hoc network, the application in the same manner. 就是说,新加入自组织网络的无线通信装置可以接收已添加了关于处于低功耗模式的无线通信装置的出现的信息的信标信号,并且确定使用与所述处于低功耗模式的无线通信装置已使用的信标时隙不同的信标时隙, 以作为新加入的无线通信装置发送的信标时隙。 That is, the radio communication apparatus newly joined the ad hoc network may receive the beacon signal has been added information regarding the occurrence of the radio communication apparatus in a low power consumption mode, and determines to use in wireless communication with the low power mode different devices have been used beacon slots beacon slot to be transmitted as a radio communication apparatus joining the new beacon slot. 新加入的无线通信装置可以确定它发送的信标时隙,从而避开处于低功耗模式的无线通信装置已经使用的信标时隙。 The newly added wireless communication device may determine its beacon slot transmitted, thus avoiding the radio communication apparatus beacon slot in low-power mode has been used.

此外,在构成自组织网络的无线通信装置改变无线通信装置发送的信标时隙的位置的情况下,应用相同方式。 In addition, when the radio communication apparatus in an ad hoc network configuration is changed beacon slot position of the radio communication apparatus transmitted, applied in the same manner. 就是说,在构成自组织网络的无线通信装置改变无线通信装置发送的信标时隙的位置的情况下,无线通信装置可以接收已添加了关于处于低功耗模式的另一无线通信装置的出现的信息的信标信号,并且确定使用与所述处于低功耗模式的另一无线通信装置已使用的信标时隙不同的信标时隙,以作为该无线通信装置发送的信标时隙。 That is the case, the wireless communication device configured to change the position of the ad hoc network beacon slot of the radio communication device transmits, the wireless communication device may receive the appearance has been added on another wireless communication device is in a low power mode beacon signal information, and determines to use in the wireless communication apparatus different from the other low-power mode used beacon slot beacon slot, slot as a beacon transmitted from the wireless communication device .

根据本发明的另一实施例,提供了一种构成自组织网络的无线通信装置。 According to another embodiment of the present invention, there is provided a wireless communication apparatus constituting the ad hoc network. 在根据本发明的无线通信装置中,每个超级帧的操作状态被确定来自以下三种操作状态:活动状态,在该状态中,按照需要执行信标信号的发送/接收和数据的发送/接收;休眠状态,在该状态中,不执行信标信号的发送/接收和数据的发送/接收;以及预接收状态,在该状态中,信标信号 In the radio communication apparatus according to the present invention, the operation state of each super frame is determined from the following three operating states: an active state, in this state, the transmission needs to be performed in accordance with the beacon signal / reception and transmission / reception of data ; dormant state, in this state, does not transmit the transmission / reception data and beacon / reception of signals; and a pre-reception state, in this state, a beacon signal

被接收,并且随后不执行信标信号的发送和数据的发送。 It is received, and transmits the beacon signal and the data transmission is not executed subsequently. 此外,还可以定义如下的预接收状态,在该状态中,信标信号被接收,并且随后不执行信标信号的发送/接收和数据的发送/接收。 In addition, the following may also be pre-defined reception state, in this state, the beacon signal is received, and then does not transmit the transmission / reception data and beacon signals / reception.

可替换地,无线通信装置在预定的超级帧周期中从休眠状态转换到预接收状态,并从相邻的无线通信装置接收信标信号,并且在根据包含在信标信号中的信息转换到活动状态时,根据信标信号,无线通信装置设置它自己的信标信号的发送时刻(实现同步)。 Alternatively, the wireless communication apparatus at a predetermined conversion of the super frame period from a receiving state to the pre-dormant state, and from an adjacent wireless communication apparatus receives the beacon signal, and the conversion activity according to the information contained in the beacon signal state, setting the transmission timing (synchronization) of its own beacon signal, beacon signals, the radio communication apparatus according to.

对于所描述的无线通信装置,该无线通信装置可以在预定的超级帧周期中转换到预接收状态,并从相邻的无线通信装置接收信标信号(这种操作模式被称为"低功耗模式"或"冬眠模式")。 For wireless communication apparatus as described, the wireless communication device can be converted in a predetermined period to the pre-super frame reception state, the radio communication apparatus and adjacent to the beacon signal is received from the (This mode of operation is referred to as "low power consumption mode "or" hibernation mode "). 此外,在根据包含在信标信号中的信息从休眠状态转换到活动状态时,无线通信装置可以提前接收来自相邻无线通信装置的信标,并获知它自己的信标信号的发送时刻。 Further, when transitioning from a sleep state to an active state based on the information contained in the beacon signal, the wireless communication device may receive a beacon from an adjacent early wireless communication device, and know its own transmission timing of the beacon signal. 此外,在从休眠状态转换到活动状态时,通过接收来自相邻无线通信装置的信标,无线通信装置可以获知相邻无线通信装置的出现和相邻无线通信 Further, when switching from the sleep state to the active state, by receiving the beacon from the neighboring wireless communication apparatus, the wireless communication apparatus can learn occur adjacent wireless communications apparatus and an adjacent wireless communication

装置的操作状态,并在活动状态中,在它自己的信标信号中描述准确的信息。 The operating state of the device, and in the active state, described accurate information in its own beacon signal. 可替换地,在上述无线通信装置中,当在预接收状态中由无线通信装置接收到的信标信号包含关于被寻址到其上的激活请求的信息的情况下, 无线通信装置转换到活动状态。 Alternatively, in the wireless communication apparatus, a case where the radio communication received by the receiving means in the pre-state, a beacon signal includes an active addressed to it on the request information, the wireless communication means to the activity status. 从而,在从休眠状态转换到活动状态时, 无线通信装置可以有足够时间被激活。 Therefore, when transitioning from a sleep state to an active state, the wireless communication device can have enough time to be activated. 一般而言,为了在从休眠状态转换到活动状态的过程中激活软件部分,需要有足够时间(例如几百毫秒)。 Generally, in order to activate the software portion of the transition from the sleep state to the active state of the process, the need for sufficient time (e.g., several hundred milliseconds).

在过去,在信标信号之间的时间间隔(例如大约40毫秒到60毫秒)期间,不能发送任何数据,从而导致系统质量下降。 During the past, the time interval between the beacon signals (e.g., from about 40 milliseconds to 60 milliseconds) and can not transmit any data, thereby resulting in decreased quality of the system. 根据本发明的实施例, 定义了预接收状态,在该状态中,无线通信装置接收信标信号,但随后不执行信标信号发送和数据发送。 According to an embodiment of the present invention, the pre-defined reception state, in this state, the radio communication apparatus receives the beacon signal, but then does not transmit the beacon signal transmission and execution data. 因此,处于预接收状态的无线通信装置可以激活软件部分,同时从本质上保持硬件部分处于休眠状态。 Thus, the radio communication apparatus in a pre-reception state may activate the software part, while keeping the hardware part is essentially in a sleep state.

可替换地,在转换到活动状态时,无线通信装置从在预接收状态中接收到的信标信号中获知存在于相邻区域中的另一无线通信装置的状态,并且宣告它自己的关于转换到活动状态的发送信标信息。 Alternatively, when switching to the active state, the state of the wireless communication device is known another wireless communication device is present in the adjacent region from the pre-received in the beacon reception state signal, and the conversion on its own declared transmitting the beacon information to the active state. 从而,在预接收状态中接收到的信标信号中包含的信息可以被反映在无线通信装置在下一超级帧中发送的信标信号中包含的信息中。 Accordingly, the information received in the pre-reception state of the beacon signal may be reflected comprising information included in the radio communication apparatus beacon signal transmitted in the next super-frame in the.

可替换地,无线通信装置包括被配置用于从相邻的无线通信装置中检测出处于低功耗模式的无线通信装置的出现的设备,以及被配置用于将关于处于低功耗模式的无线通信装置的出现的信息添加到信标信号的设备。 Alternatively, the wireless communication apparatus comprising a device configured to appear in a wireless communication device in a low power mode detected from neighboring radio communication devices, and is configured to be in wireless low power mode on message communication device is added to the beacon signal device. 低功耗模式指的是如下模式,在该模式中,处于休眠状态的无线通信装置在预定的超级帧周期中转换到预接收状态或活动状态。 Low power mode refers to a mode, in this mode, the radio communication apparatus in a sleep state transitions to a pre-reception state or an active state in a predetermined superframe period. 对于所述结构,即使存在处于低功耗模式的无线通信装置,也可以避免信标信号的冲突。 For the structure, even if the wireless communication apparatus is present in low power mode, the conflict can be avoided beacon signal.

此外,在无线通信装置改变该无线通信装置发送的信标时隙的位置的情况下,应用相同方式。 In addition, when changing the position of the beacon slot transmitted from the wireless communication device in a wireless communication apparatus, applied in the same manner. 就是说,在无线通信装置改变该无线通信装置发送的信标时隙的位置的情况下,无线通信装置可以接收己添加了关于处于低功耗模式的另一无线通信装置的出现的信息的信标信号,并且确定使用与处于低功耗模式的另一无线通信装置已使用的信标时隙不同的信标时隙,以作为该无线通信装置发送的信标时隙。 That is the case, changing the position of the beacon slot transmitted from the wireless communication device in a wireless communication apparatus, a wireless communication device may receive a letter message has added another wireless communication device is in a low power mode of about beacon signal, and determines to use different beacon beaconslot with another wireless communication apparatus in a low power consumption mode that has been used as the beacon slot transmitted from the wireless communication device.

可替换地,在低功耗模式中,处于预接收状态的无线通信装置从相邻的无线通信装置接收信标信号,并且在根据包含在信标信号中的信息转换到活动状态时,根据信标信号,无线通信装置设置信标信号的发送时刻(实现同步)。 The wireless communication device may alternatively be in low power mode, in the pre-reception state of neighboring radio communication apparatus receives the beacon signal, and when the information from the converter contained in the beacon signal to an active state, according to the letter beacon signal, the wireless communication apparatus transmits a beacon signal is provided in time (synchronized).

对于所描述的无线通信装置,在低功耗模式(也被称为"冬眠模式")中,无线通信装置可以在预定的超级帧周期中转换到预接收状态, 并且从相邻的无线通信装置接收信标信号。 For wireless communication apparatus as described, in a low-power mode (also referred to as "dormant mode"), the wireless communication device can transition to the reception state at a predetermined pre-super-frame period, and the wireless communication apparatus from the adjacent receiving a beacon signal. 此外,在根据包含在信标信号中的信息从休眠状态转换到活动状态时,无线通信装置可以提前接收来自相邻无线通信装置的信标,并获知它自己的信标信号的发送时刻。 Further, when transitioning from a sleep state to an active state based on the information contained in the beacon signal, the wireless communication device may receive a beacon from an adjacent early wireless communication device, and know its own transmission timing of the beacon signal. 此外, 在从休眠状态转换到活动状态时,通过接收来自相邻无线通信装置的信标,无线通信装置可以获知相邻无线通信装置的出现和相邻无线通信装置的操作状态,并在活动状态中,在它自己的信标信号中描述准确的信息。 Further, when switching from the sleep state to the active state, by receiving the beacon from the neighboring wireless communication devices, wireless communication devices may be learned operating state occurs and the radio communication device adjacent to a neighboring wireless communication device, and the active state is described accurate information in its own beacon signal.

在过去,在信标信号之间的时间间隔(例如大约40毫秒到60毫秒)期间,不能发送任何数据,从而导致系统质量下降。 During the past, the time interval between the beacon signals (e.g., from about 40 milliseconds to 60 milliseconds) and can not transmit any data, thereby resulting in decreased quality of the system. 根据本发明的实施例, 定义了预接收状态,在该状态中,无线通信装置接收信标信号,但随后不执行信标信号发送和数据发送。 According to an embodiment of the present invention, the pre-defined reception state, in this state, the radio communication apparatus receives the beacon signal, but then does not transmit the beacon signal transmission and execution data. 因此,处于预接收状态的无线通信装置可以激活软件部分,同时从本质上保持硬件部分处于休眠状态。 Thus, the radio communication apparatus in a pre-reception state may activate the software part, while keeping the hardware part is essentially in a sleep state.

可替换地,在转换到活动状态时,无线通信装置从在预接收状态中接收到的信标信号中获知存在于相邻区域中的另一无线通信装置的状态,并且宣告它自己的关于转换到活动状态的发送信标信息。 Alternatively, when switching to the active state, the state of the wireless communication device is known another wireless communication device is present in the adjacent region from the pre-received in the beacon reception state signal, and the conversion on its own declared transmitting the beacon information to the active state. 从而,在预接收状态中接收到的信标信号中包含的信息可以被反映在无线通信装置在下一超级帧中发送的信标信号中包含的信息中。 Accordingly, the information received in the pre-reception state of the beacon signal may be reflected comprising information included in the radio communication apparatus beacon signal transmitted in the next super-frame in the.

可替换地,无线通信装置包括被配置用于从相邻的无线通信装置中检测出处于低功耗模式的无线通信装置的出现的设备,以及被配置用于将关于处于低功耗模式的无线通信装置的出现的信息添加到信标信号的设备。 Alternatively, the wireless communication apparatus comprising a device configured to appear in a wireless communication device in a low power mode detected from neighboring radio communication devices, and is configured to be in wireless low power mode on message communication device is added to the beacon signal device. 对于所述结构,即使存在处于低功耗模式的无线通信装置,也可以避免信标信号的冲突。 For the structure, even if the wireless communication apparatus is present in low power mode, the conflict can be avoided beacon signal.

此外,在无线通信装置改变该无线通信装置发送的信标时隙的位置的情况下,应用相同方式。 In addition, when changing the position of the beacon slot transmitted from the wireless communication device in a wireless communication apparatus, applied in the same manner. 就是说,在无线通信装置改变该无线通信装置发送的信标时隙的位置的情况下,无线通信装置可以接收已添加了关于处于低功耗模式的另一无线通信装置的出现的信息的信标信号,并且确定使用与处于低功耗模式的另一无线通信装置已使用的信标时隙不同的信标时隙,以作为该无线通信装置发送的信标时隙。 That is the case, changing the position of the beacon slot transmitted from the wireless communication device in a wireless communication apparatus, a wireless communication device may receive a letter message has been added to another wireless communication device is in a low power mode of about beacon signal, and determines to use different beacon beaconslot with another wireless communication apparatus in a low power consumption mode that has been used as the beacon slot transmitted from the wireless communication device.

(7) 无线通信装置的冬眠模式中的操作状态转换 Hibernation state operating mode (7) in a wireless communication apparatus converts

图7示出了根据本实施例的无线通信装置的冬眠模式中的状态转换。 FIG 7 illustrates a conversion hibernation mode wireless communication device according to the present embodiment in a state. 本实施例定义了三个操作状态,它们是活动状态71、休眠状态72和预接收状态73,此外,图7示出了触发者和由此导致的到操作状态的转换之间的关系。 This embodiment defines three operating state, an active state are 71, 72 and the pre-sleep state 73 the receiving state, addition, FIG. 7 shows the triggering and by the resulting relationship between the conversion to the operation state.

首先,在冬眠模式中,在以与正常操作模式相同的方式执行发送/接收的超级帧的情况下,操作状态是活动状态71。 First, in hibernation mode, in the case of the normal operation mode in the same manner performing a super frame transmitted / received, the operating state is the active state 71. 在活动状态71中,如果超级帧的头部定时到达,并且该超级帧是将操作状态改变到休眠状态的超级帧,那么操作状态转换到休眠状态72 (步骤S71)。 In active state 71, if the head of the super frame timing arrives, and the super frame is changed to an operating state to a sleep state of a super frame, the operating state transitions to the sleep state 72 (step S71).

在休眠状态72中,如果超级帧的头部定时到达,并且该超级帧是将操作状态改变到活动状态的超级帧,则操作状态转换到活动状态71 (步骤S72)。 In the dormant state 72, if the head of the super frame timing arrives, and the super frame is changed to an operating state to an active state of a super frame, the operation state to the active state 71 (step S72).

此外,在休眠状态72中,如果超级帧的头部定时到达,并且该超级帧是恰好在活动状态之前的一个超级帧(预接收超级帧),则操作状态转换到预接收状态73 (步骤S73)。 Furthermore, in the sleep state 72, if the head of the super frame timing arrives, and the super frame is exactly one super-frame (super-frame receiving pre) prior to the active state, the operation state to the pre-reception state 73 (step S73 ).

在预接收状态73中,如果无线通信装置用于从相邻无线通信装置接收信标信号的管理区域结束,则操作状态再次转换到休眠状态72 (步骤S74)。 In the pre-reception state 73, if the wireless communication device from a wireless communication apparatus for receiving a beacon signal from the neighboring management area ends, the operating state transitions to the sleep state 72 again (step S74).

此外,如虚线箭头所示,如果无线通信装置从接收自相邻无线通信装置的信标信号中识别出寻址到其上的通信请求,则操作状态可以响应于请求而转换到活动状态71。 Further, as shown in dotted-line arrow, if the wireless communication device recognizes the address from the received beacon signals from neighboring radio communication apparatus in which a communication request, the operation in response to a request state transition to the active state 71. 例如,如果寻址到其上的通信请求是发送请求,操作状态则可以立即转换到活动状态71 (步骤S75)。 For example, if the request is addressed to a communication request which is transmitted, the operation state can be immediately converted to an active state 71 (step S75).

此外,如果寻址到其上的通信请求是激活请求,该无线通信装置则可以在活动状态之前提早激活诸如中央控制单元(图8中的标号810,随后描述)之类的模块,以便准备活动状态中的数据发送/接收(步骤S76)。 Further, if the communication request addressed to it on the activation request, the wireless communication device can be activated earlier such as a central control unit (reference numeral 810 in FIG. 8, described later) or the like before the active module, in order to prepare active state data transmission / reception (step S76).

图9例示出每个无线通信装置的操作模式通知。 FIG operation mode of each wireless communication apparatus shown in Example 9 notification. 图9示出了(A)在冬眠模式的活动超级帧期间信标信号的交换顺序以及(B)在冬眠模式的休眠超级帧期间信标信号的交换顺序。 Figure 9 shows (A) the switching sequence of beacon signals during a super-frame activity hibernation mode and (B) in order to exchange the beacon signal during the sleep mode, hibernation super frame.

在图9中,无线通信装置111到115中的每一个都用信标信息宣布它处于冬眠模式,并且相邻的无线通信装置了解该状态。 In FIG 9, the radio communication apparatus 111 to each of the 115 announced by the beacon information of the wireless communication apparatus which is in hibernation mode, and adjacent to understand the state. 在图9中,无线通信装置111、 113和U5处于冬眠模式,而无线通信装置112和114处于正常操作模式。 In FIG 9, the radio communication apparatus 111, 113 and U5 in hibernation mode, the wireless communication devices 112 and 114 in the normal operating mode. 无线通信装置111到115构成图l所示的自组织网络。 The wireless communication apparatus 111 to 115 constituting the ad-hoc network shown in Figure l. 如上所述,无线通信装置lll可以与无线通信装置112通信,无线通信装置U2可以与无线通信装置111和113通信,无线通信装置113可以与无线通信装置U2和114通信,无线通信装置114可以与无线通信装置113和U5通信,并且无线通信装置115可以与无线通信装置114通信。 As described above, the radio communication apparatus may lll wireless communication with a communication device 112, the wireless communication device 113 may be U2 U2 and the wireless communication device 114 to communicate with the wireless communication device 114 with the wireless communication devices 111 and 113 communicate with the wireless communications apparatus can the wireless communication device 113 and U5 communications, and the wireless communication device 115 may communicate with the wireless communication device 114.

处于冬眠模式的无线通信装置111、 113和115在休眠超级帧(B)期间不发送信标信号。 The wireless communication device 111 is in hibernation mode, do not transmit a beacon signal during the sleep 113 and the super-frame 115 (B). 但是,处于冬眠模式的无线通信装置111、 113和115在活动超级帧(A)期间也发送信标信号。 However, the wireless communication apparatus 111 is in hibernation mode, 113 and 115 are also transmitted in the super frame during the event (A) a beacon signal. 此外,处于冬眠模式的无线通信装置111、 113和115中的每一个都在将在活动超级帧期间被发送的信标信息中,例如在MAC头部信息61(图6所示)的访问控制信息605中描述下一活动超级帧的时刻信息,以便将其告知相邻的无线通信装置。 Further, the wireless communication apparatus 111 is in hibernation mode, the beacon information 113 and 115 are each to be transmitted during the active superframe, for example, information in the MAC header 61 (FIG. 6) access control time information 605 describes information of the next super frame activity, so as to be adjacent to inform the wireless communication device.

尤其在本实施例中,在冬眠模式中,预接收紧接在活动超级帧之前被执行。 In particular, in the present embodiment, in hibernation mode, the pre-reception is performed immediately before the event super frame. 例如,无线通信装置111在活动超级帧之前执行预接收。 For example, the wireless communication apparatus 111 performs pre super frame received before the event. 这样--来,通过参考如此从无线通信装置112接收到的信标信号902,在活动状态之后,即使是在信标发送/接收区域中具有信标信号的第一发送位置的无线通信装置111也可以在无需参考其它无线通信装置112到115的信标信号902到905的情况下,在超级帧的头部发送信标信号901 。 Such - a wireless communication apparatus, by referring to the thus received from the wireless communication apparatus 112 to the beacon signal 902, after the active state, having a first transmission position even if the beacon signal in the beacon transmission / reception region 111 may be without reference to other radio communication apparatus beacon signals 112 to 115 in the case of 902 to 905, 901 transmit a beacon signal at the head of the super frame.

(10) 无线通信装置的操作 Operation (10) of the wireless communication device

图IO是例示出根据本实施例的无线通信装置的操作的流程图。 FIG IO is a flowchart illustrating an operation of the radio communication apparatus according to the present embodiment. 根据本实施例的无线通信装置在预定时间段(长于超级帧的周期)中执行扫描,以便在加电之后立即检测相邻无线通信装置的信标信号(步骤 Beacon signal (step of performing radio communication apparatus according to the present embodiment a predetermined time period (the period is longer than the super frame) scan, the wireless communication apparatus to be detected immediately after the power of the adjacent

5101) 。 5101).

如果无线通信装置不能从现有的无线通信装置接收到信标信号(步骤 If the wireless communication apparatus can not be received from the existing radio communication apparatus beacon signal (step

5102) ,该无线通信装置则设置用于信标信号发送的超级帧周期(图3中的(A))和管理区域(图3中的(B))(步骤S103)。 5102), the wireless communication apparatus is set for the super frame period ((A in FIG. 3) a beacon signal transmitted) and the management area ((B in FIG. 3)) (step S103).

此后,无线通信装置在现有管理区域或新设置的管理区域中确定其自己的信标信号的发送位置,该发送位置是不与相邻无线通信装置的位置重叠的一个时刻(步骤S104)。 Thereafter, the radio communication apparatus determines the position of its own transmitted beacon signal of the existing management area or newly set in the management area, the transmission location is a location of the time does not overlap with a neighboring wireless communication device (step S104).

如果由无线通信装置管理的超级帧的头部定时已经到达(步骤S105),该无线通信装置则从步骤S106 (下面将描述)开始执行操作。 If the head of the super frame by managing the timing of the wireless communication apparatus has arrived (step S105), the wireless communication apparatus proceeds from step S106 (to be described below) begins the operation. 如果超级帧的头部定时还未到达,该无线通信装置则从歩骤S122 (下面将描述)开始执行操作。 If the head of the super frame timing has not arrived, the wireless communication device from ho step S122 (to be described below) begins the operation.

首先,无线通信装置判断该无线通信装置是否工作在冬眠模式中(步骤S106),并且还判断超级帧是活动超级帧(步骤S107)还是预接收超级帧(步骤S108)。 First, the wireless communication apparatus determines that the wireless communication device is operating in a hibernation mode (step S106), and determines further active superframe super frame (step S107), or pre-received super frame (step S108).

如果超级帧不是冬眠模式或冬眠模式中的活动超级帧,该无线通信装置则进一步判断其自己的信标信号的发送位置是否已到达(步骤S109)。 If the frame is not a super-frame SUPER hibernation mode, or hibernation mode, the wireless communication device further determines whether it is its own beacon transmission position signal has arrived (step S109). 如果信标信号的发送位置已经到达,该无线通信装置则执行信标信号的发送处理(步骤S110)。 If the transmission position of the beacon signal has arrived, the wireless communication apparatus sending process (step S110) the beacon signal is performed. 如果信标信号的发送位置尚未到达,该无线通信装置则执行接收处理,以接收来自相邻无线通信装置的信标信号(步骤Slll)。 If the transmission position of the beacon signal has not been reached, the wireless communication apparatus performs the reception process to receive a beacon signal (step S111) from neighboring wireless communication devices.

信标信号的发送/接收处理一直持续到被设置为信标区域的管理区域结束(步骤S112)。 Beacon signal transmission / reception process until the beacon is set to the end region of the management area (step S112).

另一方面,如果冬眠模式中的预接收超级帧已经到达,无线通信装置则执行接收处理,以接收来自相邻无线通信装置的信标信号(步骤S113)。 On the other hand, if the pre-hibernation mode receives super frame has arrived, the wireless communication apparatus performs a reception process to receive a beacon signal (step S113) from neighboring wireless communication devices.

信标信号的发送/接收处理一直持续到被设置为信标区域的管理区域结束(步骤SU4)。 Beacon signal transmission / reception process until the beacon is set to the end region of the management area (step SU4). 如果被设置为信标区域的管理区域结束,无线通信装置则基于相邻无线通信装置的信标信号的接收时刻执行如下处理:该处理用于校正其自己的信标信号的发送位置的定时同步(步骤S115)。 If the region is set as the beacon management area ends, the wireless communication apparatus based on the reception timing of the beacon signal of a neighboring wireless communication apparatus to execute: a process for correcting the timing of the transmission position of its own beacon signal synchronized (step S115).

此后,如果在接收到的信标信息中存在被寻址到其上的发送请求(步 Thereafter, if it is addressed to the transmission request information is present in the beacon received in (step

骤S116),无线通信装置则设置具有被请求时刻的数据接收区域(图3 Step S116), the radio communication apparatus receives the setting data region having the requested time (FIG. 3

中的Rx)(步骤sin)。 In the Rx) (Step sin).

此外,如果在作为冬眠模式的操作期间存在激活请求(步骤S118),无线通信装置则取消冬眠模式(步骤SU9)。 Further, if there is an active request (step S118) during the operation of a hibernation mode, the radio communication apparatus hibernation mode is canceled (step SU9).

可替换地,如果在预定时间段(该时间段可以被设置为例如1秒的任意时间)中未发生数据发送/接收,无线通信装置则将操作设置到冬眠模式(步骤S121)。 Alternatively, if (for example, may be set to the arbitrary time period of 1 second) predetermined time period is not data transmission / reception occurs, then the wireless communication device arranged to operate hibernation mode (step S121).

在上述设置/取消之后,或者在冬眠模式中的休眠超级帧的情况下,如果无线通信装置接收到来自通过接口连接的设备的发送数据(步骤 After the above setting / cancellation, or in the case of super-frames in the sleep hibernation mode, if the wireless communication device receives the transmission data from a device connected via the interface (step

5122) ,无线通信装置则设置数据发送区域(图3中的Tx)(步骤 5122), the wireless communication device transmission area setting data (Tx in FIG. 3) (step

5123) 。 5123).

此外,如果无线通信装置未处于冬眠模式(步骤S124),并且数据发送区域已经到达(步骤S125),无线通信装置则发送数据(步骤S126)。 Further, if the wireless communication device is not in the hibernation mode (step S124), and transmits the data region has arrived (step S125), the wireless communication apparatus transmits the data (step S126).

另一方面,如果无线通信装置处于冬眠模式,无线通信装置则取消冬眠模式(步骤S127)。 On the other hand, if the wireless communication device is in dormant mode, a wireless communication apparatus hibernation mode is canceled (step S127).

在上述取消之后,或者如果无线通信装置尚未接收到来自被连接设备的发送数据,无线通信装置则检査数据区域的使用出现与否(步骤S128)。 After the above cancellation, or if the wireless communication device is not transmitting data received from the device connected to the wireless communication apparatus checks the presence or absence of use of the data area (step S128). 如果数据接收区域(图3中的Rx)已经到达(步骤S129),无线通信装置则接收数据(步骤S130)。 If data reception region (Rx in FIG. 3) has been reached (step S129), the radio communication apparatus receives the data (step S130). 如果数据发送区域已经到达(步骤S125),无线通信装置则发送数据(步骤S126)。 If the data transmission region has arrived (step S125), the wireless communication apparatus transmits the data (step S126).

此外,如果像在冬眠模式中的休眠超级帧的情况下一样不存在数据区域的使用,则不执行处理,直到数据区域中的数据发送或数据接收完成之后超级帧头部到达;因此,只要检测发送数据出现与否就足够了。 Further, if, as in the case where Sleep hibernation mode of the super frame using the same data area does not exist, the processing is not performed, the data transmission until the data area or the data reception is completed after reaching super-frame header; Therefore, if the detection send data is present or not sufficient. 如果其自己的超级帧的头部已经到达,过程则返回步骤S105以重复一系列步 If its own head of the super frame has been reached, the process returns to step S105 to repeat a series of steps

(第一实施例的效果) (Effects of the First Embodiment)

如上所述,根据本实施例,在自组织网络100中,处于休眠状态的无 None As described above, according to the present embodiment, in the ad hoc network 100, dormant

线通信装置在冬眠模式中的预定超级帧周期中转换到预接收状态,从而使无线通信装置可以接收来自相邻无线通信装置的信标信号。 Communication apparatus converts a predetermined superframe period in hibernation mode into the pre-reception state, so that the wireless communication device may receive a beacon signal from a neighboring wireless communication device. 此外,当响应于包含在信标信号中的信息从休眠状态转换到活动状态时,无线通信装置可以通过提前接收来自相邻无线通信装置的信标来获知其自己的信标信号的发送时刻。 Further, when the information contained in the response to the beacon signal is switched from the sleep state to the active state, the wireless communication apparatus by receiving a beacon transmission timing from a neighboring wireless communication device to learn its own beacon signal in advance. 此外,在从休眠状态转换到活动状态时,通过接收来自相邻无线通信装置的信标,无线通信装置可以获知相邻无线通信装置的存在以及相邻无线通信装置的操作状态,并且在活动状态中,在其自己的信标信号中描述精确的信息。 Further, when switching from the sleep state to the active state, by receiving the beacon from the neighboring wireless communication apparatus, the wireless communication apparatus can learn about the presence of neighboring wireless communication apparatus and the operating state of the neighboring wireless communication apparatus, and in the active state is described accurate information in its own beacon signal.

此外,在由无线通信装置在预接收状态中接收到的信标信息包含关于被寻址到其上的激活请求的情况下,无线通信装置转换到活动状态。 Further, in the beacon information received by the pre-reception state on the wireless communication device includes a case where the activation request which is addressed to the wireless communication means to the active state. 于是,在从休眠状态转换到活动状态时,无线通信装置可以有足够时间被激活。 Thus, when transitioning from a sleep state to an active state, the wireless communication device can have enough time to be activated. 一般而言,为了激活从休眠状态到活动状态的转换过程中的软件部分,需要拥有足够的时间(例如几百毫秒)。 In general, to activate the software portion from a dormant state to an active state of the conversion process, the need to have sufficient time (e.g., several hundred milliseconds). 在过去,在信标信号之间的 In the past, between beacon signals

时间间隔(例如大约40毫秒到60毫秒)期间不能发送数据,从而会导致系统质量下降。 Can not be sent during the time interval (e.g., approximately 40 ms to 60 ms) of data, which will lead to decline in the quality of the system. 在本实施例中,定义了预接收状态,在该状态中,无线通信装置接收信标信号,但其后不执行信标信号的发送/接收以及数据的发送/接收。 In the present embodiment, the pre-defined reception state, in this state, the radio communication apparatus receives the beacon signal, the beacon signal transmission but then not executed / received, and transmitting / receiving data. 因此,处于预接收状态的无线通信装置可以激活软件部分,同时在本质上保持硬件部分处于休眠状态中。 Thus, the radio communication apparatus in a pre-reception state may activate the software part, while retaining essentially the hardware part is in a sleep state.

(B)第二实施例下面将描述本发明的第二实施例。 (B) Second Embodiment The second embodiment of the present invention will be described.

如第一实施例所描述的,这里采用了如下方法:通过在构成自组织网络的无线通信装置之间彼此告知前一信标时隙的使用状态,来检测未被相邻无线通信装置占用的信标时隙。 As described in the first embodiment, there is employed a method of: using a previous state by notifying beacon slots among the wireless communication device constituting the ad-hoc network with one another to detect the radio communication apparatus is not occupied by an adjacent beacon slot. 就是说,每个无线通信装置接收来自相邻无线通信装置的信标信号,并将接收到的信标时隙描述为"已被占用"。 That is, each wireless communication device receives a beacon signal from an adjacent wireless communications apparatus, and the received beacon slot described as "occupied." 此外,采用了以如下方式操作网络的方法:使用上一信标时隙的无线通信装置用未被占用的信标时隙代替上一信标时隙,从而保持信标周期尽可能短。 Further, a method using the network operates as follows: the radio communication apparatus using a beacon on a time slot instead of using a beacon slot unoccupied beacon slots, thereby maintaining the beacon period as short as possible.

但是,在第一实施例所描述的冬眠模式中,由于在休眠超级帧中未从无线通信装置发送信标信号,因此存在如下可能性:某些无线通信装置错误地确定信标时隙未被占用,并检测信标时隙。 However, the hibernation mode described in the first embodiment, since the radio communication apparatus does not transmit a beacon signal, and therefore there is a possibility in the super-frame sleep: Some radio communication apparatus erroneously determines a beacon slot is not occupancy, and detects a beacon slot.

此外,在使用上一信标时隙的无线通信装置用未被占用的信标时隙代替上一信标时隙的情况下,存在如下可能性:由于以相同的信标时隙发送,因此由另一可工作在冬眠模式中的无线通信装置所发送的信标信号与这个用未被占用的信标时隙代替上一信标时隙的无线通信装置的信标信号相冲突。 Further, the wireless communication device uses a beacon slot is replaced by an unoccupied beacon slots on a case where the beacon slots, there is a possibility: Since transmitted in the same beacon slot, so beacon signal of the wireless communication apparatus from the beacon signal of another wireless communication apparatus operable in a hibernation mode and transmitted using this unoccupied beacon slots instead of the previous beacon slot conflicts.

在本实施例中,将就如下两个方法进行描述,第一方法是:防止另一通信装置将信标信号发送到在多个超级帧中只能利用它发送一次信标信号的信标时隙,第二方法是:在用未被占用的信标时隙代替上一信标时隙的情况下,防止无线通信装置用已被占用的信标时隙代替上一信标时隙。 When prevented from another communication apparatus transmits a beacon signal to a plurality of super-frame can use it to send a beacon signal beacon: In the present embodiment, the following two methods will be described, the first method is gap, the second method is: in the case where instead of using a beacon slot unoccupied beacon slot, the radio communication apparatus preventing the place of a beacon slot is occupied by beacon slots.

图19示出了根据本实施例的无线通信装置的操作的流程图。 FIG 19 shows a flowchart of the operation of the radio communication apparatus of the present embodiment. 每个无线通信装置根据在MAS的开始时刻到达时为每个MAS设置的使用方法来执行每个操作。 Each wireless communication apparatus to perform each operation is provided using a method according to each MAS in the arrival time of the start of the MAS.

首先,如果MAS是信标周期MAS (步骤S201),并且它是发送信标时隙的时刻(S202),无线通信装置则获取信标参数(步骤S203), 并执行发送处理(步骤S223)。 First, if a beacon period MAS MAS (step S201), and it is time to transmit a beacon slots (S202), the radio communication apparatus is acquired standard parameter information (step S203), and executes transmission processing (step S223).

如果MAS是信标周期MAS (步骤S201),并且它不是发送信标时隙的时刻,无线通信装置则执行信标接收处理(步骤S204)。 If MAS MAS beacon period (step S201), and it is not time to transmit a beacon slot, the radio communication apparatus beacon reception processing is performed (step S204). 如果存在信标接收(步骤S205),无线通信装置则将自己的信标时隙信息位图(图15中的704)的相应部分设置为"11:已被占用"(步骤S206), 并将关于相应无线通信装置的信息注册到信标时隙管理信息(图18中的903)中(步骤S207)。 If the presence of the beacon received (step S205), the wireless communication apparatus will own beacon slot bitmap information (704 in FIG. 15) of the respective portions is set to "11: is occupied" (step S206), and information about the respective wireless communication devices registered management information to the beacon slot (903 in FIG. 18) (step S207).

此外,如果存在冬眠模式信息单位(图17)的描述(步骤S208), 无线通信装置则指定休眠超级帧周期(步骤S209)。 Further, if the hibernation mode information unit (FIG. 17) is described (step S208) is present, the wireless communication device specifies sleep super frame period (step S209). 在从下一超级帧开始进入休眠状态的情况下(步骤S210),无线通信装置将相应的无线通信装置注册为冬眠模式中的休眠状态(步骤S211)。 In the case of beginning to enter the sleep state from the next super frame (step S210), the wireless communication apparatus corresponding to the wireless communication device registered as a sleep state (step S211) hibernation mode.

此外,如果无线通信装置只检测到信标信号的PHY信号,并且头部校验序列(图6中的62)或帧校验序列(图6中的64)存在错误(步骤S212),无线通信装置则将自己的信标时隙信息位图(图15中的704) 的相应部分设置为"01:只暂时使用/检测"(步骤S213)。 Further, if the wireless communication signal to the PHY device detects only the beacon signal, and the presence of the header check sequence (62 in FIG. 6) or frame check sequence (64 in FIG. 6) the error (step S212), the radio communication apparatus will own beacon slot bitmap information (704 in FIG. 15) of the respective portions is set to "01: only temporary use / detection" (step S213). 如果在相应的信标时隙中有已注册的通信装置(步骤S214),并且连续无接收的次数己达到预定次数(步骤S215),无线通信装置则将自己的信标时隙信息位图(图15中的704)的相应部分设置为"00:未被占用"(步骤S216),并且取消相应的通信装置信息的注册(步骤S217)。 If there is a communication device (step S214) is registered in the corresponding beacon slot, and the number of consecutive non-reception has reached the predetermined number of times (step S215), the wireless communication apparatus will own beacon slot bitmap information ( 704 in FIG. 15) of the respective portions is set to "00: unoccupied" (step S216), and cancels the corresponding communication device registration information (step S217).

此外,如果在相应的信标时隙中不存在已注册的通信装置,或者如果无接收的次数小于预定次数,则无线通信装置退出这一系列步骤。 Further, if the communication device is registered is not present in the corresponding beacon slot, or if the number is less than a predetermined number of times without receiving, the wireless communication apparatus to exit the series of steps.

此外,如果不存在信号检测,并且信标时隙的边界己经到达(步骤S218)且存在冬眠注册(步骤S219),无线通信装置则将自己的信标时隙信息位图(图15中的704)的相应部分设置为"10:已分派休眠状态"(步骤S220)。 Also, if the signal is detected is not present, and the beacon slot boundary has arrival (step S218) and registered in the hibernation (step S219), the radio communication apparatus will own beacon slot bitmap information (15 in FIG. 704) to a respective portion of "10: the assigned sleep state" (step S220).

此外,如果不存在冬眠注册,过程则移动到步骤S214,在这里无线通信装置检査连续无接收的次数是否已达到预定次数,以判断是否取消注册。 Further, if the hibernation registration does not exist, the process moves to step S214, where whether the number of the radio communication apparatus continuously without checking received has reached a predetermined number of times, to determine whether to cancel the registration.

如果MAS是数据发送MAS (数据TxMAS)(步骤S221),无线通信装置则从缓冲器获取数据(步骤S222),并执行发送处理(步骤 If the data transmission MAS MAS (data TxMAS) (step S221), the wireless communication device acquires data from the buffer (step S222), and executes transmission processing (step

5223) 。 5223).

此外,如果MAS是数据接收MAS (数据Rx MAS)(步骤 Further, if the received data is MAS MAS (MAS the Rx data) (step

5224) ,无线通信装置则执行数据接收处理(步骤S225)。 5224), a wireless communication apparatus executes data reception processing (step S225). 此外,如果无线通信装置接收到被寻址到其上的数据,无线通信装置则将数据存储在缓冲器中,并将其输出到通过接口(未示出)连接的应用设备。 Further, if the wireless communication device receives the data addressed to which the wireless communication device the data is stored in the buffer, and outputs it via an interface (not shown) connected to the application device.

此外,如果无线通信装置从通过接口连接的应用设备接收到发送数据(步骤S226),无线通信装置则按照需要设置数据发送MAS (步骤S227)。 Further, if the wireless communication apparatus from the received transmission data (step S226) through the application interface is connected, the radio communication apparatus is provided according to need data transmission MAS (step S227).

如上所述,根据本实施例,为了在冬眠模式的多个超级帧中识别出信标信号只利用它被发送一次的信标时隙,指示冬眠模式中的预留使用的状态参数被添加到宣告信标时隙使用状态的信息单位中,从而可以防止另一通信装置将信标信号发送到该信标时隙。 As described above, according to the present embodiment, in order to identify the plurality of beacon signals in a hibernation mode using only the super-frame which is transmitted once a beacon slot reserved state parameter indicating use hibernation mode is added to the information declared by the beacon slot used state, thereby preventing further communication apparatus transmits a beacon signal to the beacon slot. 此外,可以防止无线通信装置在用未被占用的信标时隙代替上一信标时隙的情况下,用已被占用的信标时隙代替上一信标时隙。 Further, the radio communication apparatus can be prevented in the case where instead of using a beacon slot unoccupied beacon slots, instead of the previous beacon slot is occupied by beacon slots.

(C)第三实施例 (C) Third embodiment

下面将描述本发明的第三实施例。 The third embodiment of the present invention will be described.

对于应用到无线个人局域网(PAN)的媒体访问技术,正在研发正EE 802.15.3,并且对于多频带OFDM (MB-OFDM)的访问方案,正在研发分布式MAC草案规范。 For applications to wireless personal area network (PAN) media access technology being developed positive EE 802.15.3, and for multi-band OFDM (MB-OFDM) access scheme, the distributed MAC is developing draft specification. 作为用于在IEEE 802.15.3或分布式MAC中定义的低功耗操作的休眠状态的设置方法,可以使用冬眠模式(休眠模式),如第一和第二实施例所述,在冬眠模式中,无线通信装置在转换到一个超级帧的休眠状态之后,经过多个超级帧而转换到活动状态。 As a method for setting a sleep state for low power operation defined in the IEEE 802.15.3 MAC is distributed or, you may be used hibernation mode (sleep mode), as described in the first and second embodiments, in hibernation mode , the wireless communication device after conversion to a sleep state of a super frame, a plurality of super-frames after transition to the active state.

分布式MAC定义了一种结构,该结构用于使用在超级帧中的信标周期期间在相邻通信装置之间交换的信标帧来交换各种类型的信息和参数。 Distributed MAC defines a structure that is used between adjacent beacon frames exchanged during the communication apparatus beacon period in the super-frame used to exchange various types of information and parameters. 更具体而言,该结构被构造为:用于以利用分布式预留协议(DRP)的预留通信控制方法来设置传输线路的请求和响应被交换,以作为一种隐式协商技术。 More specifically, the structure is configured to: reserve a communication control method for use in a distributed reservation protocol (DRP) to the transmission line setting request and response are exchanged, as an implicit negotiation techniques.

在该技术中,由于不能保证在不稳定的无线通信环境中总能接收到特定信号,因此即使通信装置基本上在超级帧中只发送一次的信标信号无法被接收到,也不能直接判定该通信装置已经消失,但是如果信标信号连续多次无法被接收到,则检测出该通信装置已经消失。 In this technique, because it is not always able to receive a wireless communication environment unstable particular signal, even if the communication apparatus transmits substantially only the beacon signal in a super-frame can not be received, the determination can not be directly communication apparatus has disappeared, but repeatedly if the beacon signal is not received, it is detected that the communication apparatus has disappeared.

但是,在与工作在如第一和第二实施例所述的冬眠模式的通信装置交换各种参数的情况下,由于该通信装置在执行参数请求的超级帧之后转换到休眠状态,因此在下一活动超级帧之前,要不利地等待参数响应的发送。 However, in the case of working in the various parameters as in the first exchange and a communication apparatus according to the second embodiment hibernation mode, since the communication device transitions to a sleep state after the super frame request execution parameter, so the next super frame before the event, to be adversely waiting to send a response parameter.

在将已有的消失和检测技术应用到工作在如第一和第二实施例所述的冬眠模式下的通信装置的情况下,由于无法检测到信标在连续的超级帧中消失,因此需要利用下一活动超级帧来检测连续的消失。 The disappearance of the existing application and detection techniques work in the case of a communication device in a hibernation mode as in the first embodiment and the second embodiment, since the disappearance of the beacon can not be detected in consecutive super-frames, it is necessary use the next activity to detect super-frame continuous disappear. 因此,即使通信装置己经消失,也无法在长时间中获知准确的出现。 Thus, even if the communication apparatus has disappeared, we can not know the exact time in the occurrence.

在本实施例中,作为一种用于解决上述问题的技术,将描述一种用于限定冬眠模式的操作的方法,在该方法中,通信装置在经由多个超级帧转换到休眠状态之后,在多个超级帧中保持活动状态,并且进一步转换到休眠状态。 In the present embodiment, as a technology to solve the above problems a method for, a method for defining a hibernation mode of operation will be described, in the method, the communication device after conversion to a sleep state via a plurality of super-frames, It remains active in a plurality of super-frames, and further converted to the sleep state.

此外,在完成冬眠持续时间之后,通信装置在超级帧8中转换到活动状态。 Further, after completion of the duration of hibernation, the communication means to the active state in the super frame 8. 一般而言,除非另外指定,否则活动超级帧被定义为只有一个超级帧(超级帧8),从而实现低功耗操作。 In general, unless otherwise specified, it is defined as active super frame only a super-frame (super-frame 8), in order to achieve low power operation.

此外,通信装置在超级帧9中再次转换到休眠状态,并继续冬眠操作。 In addition, the communication in the super-frame conversion means 9 to the sleep state again, and continue the hibernation. 就是说,通信装置在8个超级帧中执行冬眠操作。 That is, in the communication apparatus 8 performs the hibernation super-frame. 此外,通信装置在其中的7个超级帧中处于休眠状态,并在一个超级帧中处于活动状态。 Further, the communication device 7 in a super frame in which the dormant state, and is active in a super-frame.

如图22所示,活动超级帧0被设置,并且从下一帧开始的六个超级帧被设置为冬眠持续时间。 22, the super frame 0 is set active, and six from the next frame starts super-frame is set as duration of hibernation. 通信装置在超级帧1到6中转换到休眠状态。 The communication device transitions to the sleep state into the super frame 16. 此外,通信装置在超级帧6中暂时转换到预接收状态,以用于与相邻信标同步。 Further, the communication means is temporarily converted in the super frame 6 to the pre-reception state, for synchronization with the adjacent beacons.

在这种情况下,如果充分准备了多个活动超级帧,则可以将通信装置构造为不一定转换到预接收状态。 In this case, if a plurality of events fully prepared super-frames, the communication device may be configured so as not necessarily to the pre-conversion reception state.

此外,在完成冬眠持续时间之后,通信装置在超级帧7中转换到活动状态。 Further, after completion of the duration of hibernation, the communication means to the active state in the super frame 7. 此外,由于两个超级帧被设置为活动持续时间,因此通信装置在两个超级帧7和8中连续处于活动状态。 Further, since the two super frame duration is set to be active, the communication device in the active state continuously in two super frame 7 and 8.

此外,通信装置在超级帧9中再次转换到休眠状态,并继续重复冬眠操作。 In addition, the communication in the super-frame conversion means 9 to the sleep state again, and continues to repeat the hibernation. 就是说,通信装置在八个超级帧中执行冬眠操作。 That is, the communication device performs the hibernation eight super-frame. 此外,通信装置在其中的六个超级帧中处于休眠状态,并在两个超级帧中处于活动状态。 Further, six communication device wherein the super frame in the sleep state, and is active in both the super-frame.

如果在S1121处,超级帧不是活动超级帧而是预接收超级帧,无线通信装置则不执行数据发送/接收,并且过程移动到S1126。 If S1121, the super-frame SUPER-frame rather than receiving the pre-super-frame, the radio communication apparatus for data transmission / reception is not performed, and the process moves to S1126.

此外,如果无线通信装置己经从接口接收到发送数据,从而缓冲器存储该数据(S1126)并且无线通信装置处于冬眠模式(S1127),无线通信装置则取消冬眠模式(S1128)。 Further, if the wireless communication apparatus transmits the data received from the interface to have such buffer stores the data (S1126) and the wireless communication device in a dormant mode (S1127), the wireless communication apparatus hibernation mode is canceled (S1128).

此外,如果对端通信装置处于冬眠超级帧(SU29),无线通信装置则暂时将处理挂起。 Further, if the super frame in a dormant (SU29) of the side communication apparatus, the radio communication apparatus temporarily suspend the process. 如果对端通信装置处于另一状态(活动或预接收状态),无线通信装置则获取对端通信装置可以使用的MAS (S1130)。 If in another state (or pre-event reception state) of the side communication apparatus, the radio communication apparatus side communication apparatus access to MAS can be used (S1130). 此外,如果DRP预留设置是必需的(S1131),无线通信装置则设置自己的发送DRP (S1132)并设置DRP发送MAS (S1133)。 Further, if the DRP reservation setting is required (S1131), the wireless communication apparatus is set DRP own transmission (S1132) and sets the DRP transmission MAS (S1133).

另一方面,如果DRP预留设置在S1131处不是必需的,无线通信装置则设置被寻址到相应通信装置的PCA发送(S1134),并设置自己的PCA使用信息(S1135)。 On the other hand, if the DRP reservation is not necessary provided at S1131, the wireless communication apparatus is set to be addressed to the respective communication device transmits PCA (S1134), and to set their own PCA usage information (S1135).

如果在预定时间段内不存在数据发送/接收(S1136),无线通信装置则设置冬眠模式(S1137)。 If the data does not exist in a predetermined time period transmission / reception (S1136), the radio communication apparatus hibernation mode is set (S1137). 此外,如果需要多个活动超级帧(S1138), 无线通信装置则设置活动超级帧的数目(S1139)。 Further, if multiple active super-frames (S1138), the wireless communication device number (S1139) of setting active superframe. 如果这是第一次冬眠模式设置(S1140),无线通信装置则将倒计数的超级帧数目设置到冬眠操作的开始(S1141)。 If this is the first hibernation mode setting (S1140), the number of super-frames will count down the wireless communication device is provided to start hibernation operation (S1141).

此外,在上述设置完成之后,过程返回SU05,并且重复这一系列步骤。 Further, after the above setting is completed, the process returns to SU05, and repeats the series of steps.

(第三实施例的效果) 如上所述,根据本实施例,通过在多个超级帧中保持活动状态,可以在处于冬眠模式的通信装置之间交换各种参数,从而执行信标发送/接收。 (Effect of third embodiment) As described above, according to the present embodiment, by holding the plurality of super-frames in the active state, the various parameters may be exchanged between the communication apparatus is in hibernation mode so as to perform beacon transmission / reception . 通过在多个超级帧中保持活动状态,可以立即检测到工作在冬眠模式中的通信装置的消失。 By maintaining an active state in the plurality of super-frames may be detected immediately disappears in a communication device operating in a hibernation mode.
