### 特征比对表格

技术特征描述及公开性判断结果对比文件原文引用公开性论述
**特征A**:确定第一设备感测响应消息包括多个远程近场通信NFC设备之间的一个或多个冲突,《直接公开》[0109]段:If there are a plurality of targets around the initiator, and the initiator requests the NFCIDs from the targets around itself, then two or more targets may simultaneously send their NFCIDs. If this happens, the NFCIDs sent from the two or more targets collide, preventing the initiator from recognizing the collided NFCIDs.对比文件明确指出,当存在多个目标时,它们可能同时发送其NFCID,从而导致NFCID发生冲突,使发起方无法识别。这相当于公开了“确定第一设备感测响应消息(即轮询响应帧)包括多个远程NFC设备之间的一个或多个冲突”。本领域技术人员能毫无疑义地得出该技术特征。
**特征B**:所述第一设备感测响应消息响应于第一设备感测请求消息,《直接公开》[0091]段:In the SDD processing, the initiator sends the polling request frame. ... Upon receipt of the polling request frame, each target creates its own NFCID by a randomly generated number, and sends out a frame called "polling response frame" that includes the generated NFCID.对比文件明确描述了轮询请求帧(polling request frame)和轮询响应帧(polling response frame)的请求-响应关系。轮询响应帧是响应于轮询请求帧而发送的。这直接公开了“第一设备感测响应消息响应于第一设备感测请求消息”。
**特征C**:通过对所述第一设备感测响应消息执行冲突消除,来识别所述多个远程NFC设备中的第一远程NFC设备,《直接公开》[0140]段:If it is determined in step S15 that the polling response frame from other apparatus has been properly received, the NFC apparatus proceeds to step S16 wherein the NFC apparatus recognizes the other apparatus that has returned the polling response frame as a passive mode target, recognizes the NFCID of the target by the NFCID included in the polling response frame...对比文件描述了在SDD处理中,如果轮询响应帧被正确接收,则发起方从该帧中识别出目标的NFCID,从而识别出该目标设备。这个过程本身就是一种冲突消除(识别出一个设备),尤其是在多个设备响应可能冲突的背景下。因此,该特征被直接公开。
**特征D**:向所识别的第一远程NFC设备发送睡眠请求消息,《直接公开》[0145]段:Thereafter, the NFC apparatus proceeds to step S18 wherein the NFC apparatus sends the command DSL_REQ at the n-th rate to the target (passive mode target) whose NFCID has been stored in step S17 so as to set the target to the deselect state...对比文件明确指出,在识别出目标的NFCID并存储后,发起方向该目标发送DSL_REQ命令,以使其进入取消选择(deselect)状态。DSL_REQ命令的作用是禁止目标响应后续的轮询请求帧,其功能与目标专利中的“睡眠请求消息”相同。因此,该特征被直接公开。
**特征E**:所述睡眠请求消息使所识别的第一远程NFC设备转入睡眠状态,《直接公开》[0122]段:The target that receives the command DSL_REQ sends the response DSL_RES in reply to the command DSL_REQ and it is set to the deselect state, so that it will no longer respond to or no longer send a response to commands other than the command WUP_REQ.对比文件公开了目标在收到DSL_REQ命令后,会进入“deselect state”(取消选择状态)。在此状态下,目标不再响应除WUP_REQ之外的命令。这相当于使设备转入一种“睡眠状态”,即不响应后续的感测请求。该特征被直接公开。
**特征F**:所述睡眠状态禁止所识别的第一远程NFC设备对第一设备感测请求消息进行响应,《直接公开》[0122]段:... so that it will no longer respond to or no longer send a response to commands other than the command WUP_REQ. <br> [0145]段:... so as to set the target to the deselect state, thereby prohibiting the target from responding to the polling request frames transmitted thereafter.对比文件两次明确指出,处于取消选择状态(deselect state)的目标被禁止响应后续的轮询请求帧(polling request frames)。轮询请求帧即相当于设备感测请求消息。因此,该特征被直接公开。
**特征G**:发送第二设备感测请求消息,《直接公开》[0100]段:In this case, the initiator resends a polling request frame to request the retransmission of the polling response frames with their NFCIDs included therein from the targets #1 and #3.对比文件描述了在初始轮询请求帧发送后,因响应冲突导致某些设备未被识别,发起方会重新发送(resend)轮询请求帧。这相当于发送了“第二设备感测请求消息”。该特征被直接公开。
**特征H**:接收包括所述多个远程NFC设备之间的冲突的第二设备感测响应消息,《直接公开》[0100]段:...the initiator resends a polling request frame... <br> [0109]段:If there are a plurality of targets... then two or more targets may simultaneously send their NFCIDs. If this happens, the NFCIDs sent from the two or more targets collide...对比文件公开了重新发送轮询请求帧(第二设备感测请求)后,仍然可能从多个剩余的目标(未处于取消选择状态的设备)接收到轮询响应帧,而这些响应帧之间仍然可能发生冲突。因此,该特征被直接公开。
**特征I**:通过对所述第二设备感测响应消息执行冲突消除,来识别所述多个远程NFC设备中的第二远程NFC设备,《直接公开》[0100]段:Thereafter, the transmission of the polling request frame from the initiator and the transmission of the polling response frames from the targets are repeated until the initiator recognizes the NFCIDs of all the targets #1 through #5 located around the initiator. <br> [0140]段:... recognizes the NFCID of the target by the NFCID included in the polling response frame...对比文件描述了重复进行轮询请求和响应的过程,直到识别出所有目标。这个过程隐含了在每次迭代(包括第二次发送轮询请求后)中,通过对接收到的轮询响应帧(第二设备感测响应)进行分析来识别目标(例如第二远程NFC设备)。结合已公开的识别单个设备的方法,该特征被直接公开。
**特征J**:其中,冲突是指来自远程NFC设备的设备感测响应消息中有如下指示:针对单个值,既接收到“0”比特也接收到“1”比特。未找到对应描述。对比文件虽然描述了“冲突”(collide),但其定义是多个目标同时发送NFCID导致发起方无法正确接收帧(帧级冲突)。并未涉及或定义目标专利中所述的比特级冲突概念,即针对消息中的单个比特位,既收到“0”也收到“1”。因此,该特征未被对比文件公开。
**特征K**:将所述第一设备感测响应消息存储在存储结构中的第一位置中,并且将所述第二设备感测响应消息存储在所述存储结构中的第二位置中。未找到对应描述。对比文件没有提及将接收到的轮询响应帧(设备感测响应消息)存储在特定的“存储结构”中,也未提及按不同位置(如第一位置、第二位置)进行存储。该特征未被对比文件公开。
**特征L**:接收无冲突的设备感测响应消息。未找到对应描述。对比文件描述了冲突的发生以及通过重复轮询来解决冲突,但未明确描述或提及最终会接收到一个“无冲突的设备感测响应消息”。该特征未被对比文件公开。
**特征M**:通过使用所接收的无冲突设备感测响应消息对所述存储结构中的、所述第一位置中的所述第一设备感测响应消息和所述第二位置中的所述第二设备感测响应消息进行分析,来确定所述第一设备感测响应消息和所述第二设备感测响应消息的无冲突版本。未找到对应描述。该特征依赖于特征K(存储结构)和特征L(无冲突消息)的存在。由于对比文件未公开这些基础特征,因此也不可能公开基于它们进行的这种特定分析过程。该特征未被对比文件公开。
**特征N**:其中,所述第二设备感测响应消息覆写所述第一设备感测响应消息。未找到对应描述。对比文件没有提及任何关于后续接收的设备感测响应消息覆写先前存储的消息的操作或机制。该特征未被对比文件公开。
**特征O**:其中,所述多个远程NFC设备中的每个远程NFC设备被配置为使用NFC-A射频RF技术。[0004]段:Type A adopts the Philips' MIFARE system... <br> [0022]段:The communication system shown in Fig. 1 may be used as an IC card system...对比文件提到了Type A技术,并说明其系统可用作IC卡系统。然而,在描述SDD处理(即识别多个设备的过程)时,并未明确限定参与该过程的所有目标设备(远程NFC设备)都必须被配置为使用NFC-A RF技术。目标专利强调其技术方案专门针对NFC-A设备,而对比文件的应用范围更广。因此,该特征未被对比文件直接或隐含公开。
**特征P**:其中,所述第一设备感测响应消息和所述第二设备感测响应消息是如在NFC论坛数字协议规范中定义的SENS_RES消息。[0091]段:...sends out a frame called "polling response frame"...对比文件使用“polling response frame”(轮询响应帧)这一术语,而非目标专利中明确限定的标准术语“SENS_RES消息”。虽然二者功能可能相似,但作为具体的技术特征,术语的特定定义(“如在NFC论坛数字协议规范中定义的”)未被对比文件公开。
**特征Q**:其中,所述第二设备感测请求消息是如在NFC论坛数字协议规范中定义的SENS_REQ消息。[0091]段:In the SDD processing, the initiator sends the polling request frame.对比文件使用“polling request frame”(轮询请求帧)这一术语,而非目标专利中明确限定的标准术语“SENS_REQ消息”。虽然二者功能可能相似,但作为具体的技术特征,术语的特定定义(“如在NFC论坛数字协议规范中定义的”)未被对比文件公开。
**特征R**:其中,所述睡眠请求消息是如在NFC论坛数字协议规范中定义的SLP_REQ消息。[0122]段:The command DSL_REQ is sent when an initiator sets a target to a deselect state.对比文件使用“DSL_REQ”命令来实现使目标进入不响应状态的功能,而非目标专利中明确限定的标准术语“SLP_REQ消息”。虽然功能相似,但作为具体的技术特征,术语的特定定义(“如在NFC论坛数字协议规范中定义的”)未被对比文件公开。
**特征S**:其中,所述多个远程NFC设备包括阅读器设备、写入设备、标签、卡以及对等设备中的至少一个。《直接公开》[0021]段:Further alternatively, the NFC apparatuses 1 through 3 may be used as a personal digital assistant (PDA), a personal computer (PC), a cellular telephone, a wristwatch, a pen, or other communication system. In other words, the NFC apparatuses 1 through 3 are the apparatuses for performing near field communication, and are not limited to the IC cards, readers/writers, etc. of an IC card system.对比文件明确指出,NFC装置可用于各种设备,包括但不限于IC卡、读写器等。这涵盖了目标专利中列举的阅读器设备、写入设备、标签、卡(IC卡)以及对等设备(如PDA、PC、手机等可进行对等通信的设备)。因此,该特征被直接公开。
**特征T**:还包括:与发送了设备感测响应消息的每个设备执行单个设备检测通信以便获得NFC设备标识符NFCID。《直接公开》[0090]段:For the initiator to exchange data with the target, the target to exchange data with must be identified. For this purpose, after beginning the output of the electromagnetic waves by the initial RFCA processing, the initiator requests NFCIDs, which is the information for identifying targets, from one or more targets located in the vicinity of the initiator. The targets existing near the initiator send the NFCIDs identifying themselves to the initiator in response to the request from the initiator. <br> [0091]段:In the SDD processing, the initiator sends the polling request frame. ... the target ... sends out a frame called "polling response frame" that includes the generated NFCID. The initiator recognizes the NFCID of the target by receiving the polling response frame sent from the target.对比文件详细描述了“单个设备检测(SDD)处理”的过程:发起方发送轮询请求帧,目标响应以包含其NFCID的轮询响应帧,从而使发起方获得目标的NFCID。这完全对应于目标专利中的“与发送了设备感测响应消息的每个设备执行单个设备检测通信以便获得NFC设备标识符NFCID”。该特征被直接公开。
