[0075] The solution of the embodiment of the present application can be applied to a wireless short-range communication system to reduce wireless perception interruption situations while realizing wireless perception based on the wireless short-range communication system.
[0076] In this application, the wireless short-range communication system may be a communication system based on any wireless short-range communication technology. There are many possibilities for the wireless short-range communication system, such as a wireless short-range communication system supporting low-power communication technology or other types of wireless short-range communication systems, and this application does not impose any restrictions on this.
[0077] Nodes in the wireless short-range communication system of the present application may include a management node and at least one managed node. A wireless network connection is established between the management node and the at least one managed node. The management node and the managed nodes are connected to jointly perform specific communication functions, and the management node and the managed nodes connected thereto together form a communication domain.
[0078] For example, the communication domain may be a range area in which the management node can communicate with the managed nodes, and the management node may control each managed node within the communication domain where the management node is located.
[0079] A wireless short-range communication system may include multiple management nodes. Different management nodes correspond to different communication domains, and accordingly, different management nodes manage different managed nodes.
[0080] For example, in some wireless short-range communication systems, management nodes are called G nodes, and managed nodes are called T nodes. At a given time, a T node can only access one communication domain at a time—that is, a G node within that domain. A G node can manage and control any T nodes within its communication domain.
[0081] The following will be combined with the drawings in the embodiments of this application to clearly and completely describe the technical solutions in the embodiments of this application. Obviously, the embodiments described are only part of the embodiments of this application, not all of the embodiments. Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0082] As shown in Figure 1, it shows a schematic flow diagram of a wireless sensing method provided in an embodiment of the present application. This process is applied to a first management node side in a wireless short-range communication system, where the first management node is in a first communication domain. The method of this embodiment may include:
[0083] S101: Obtain perception information sent by a second management node in a second communication domain.
[0084] The sensing information is used to sense the target object, which is the object currently sensed by the second management node, that is, the object that the second management node needs to sense using wireless sensing. It is understandable that the target object that needs to be sensed in wireless sensing can also be called a sensing target.
[0085] In this application, the second management node sends perception information to the first management node, indicating that the second management node needs to transfer the wireless perception task in which it participates in perception to the first management node, so that the first management node can continue to perform wireless perception on the target object.
[0086] S102: Based on the perception information, configure perception configuration information for the managed nodes in the first communication domain.
[0087] It can be understood that the perception information is the information related to the second management node's participation in perceiving the target object, and wireless perception of the target object within the first communication domain can be performed in combination with the perception information to configure perception configuration information for the managed nodes within the first communication domain, so that the management nodes and managed nodes within the first communication domain can participate in wireless perception.
[0088] The perception configuration information configured for the managed node is information required for the managed node to participate in perceiving the target object.
[0089] For example, the perception configuration information includes at least: a signal type of the perception signal and a transmission format of the perception signal.
[0090] The signal type of the perception signal is the signal type used to transmit the perception signal. The signal type of the perception signal can be various signal types currently available in wireless short-range communication systems, such as a detection signal or a reference signal. Of course, the signal type used by the perception signal can also be other signal types that may appear in the future, without limitation.
[0091] The transmission format of the perception signal is used to indicate wireless communication parameters for transmitting the perception signal. The transmission format of the perception signal may include one or more wireless communication parameters required for transmitting the perception signal, without limitation.
[0092] For example, the sending format of the perception signal includes at least: a frame number and a frame period.
[0093] The frame number is the frame number of a radio frame or superframe, which identifies the radio frame or superframe in which the perception signal is sent or received. Based on the frame number, the first management node and each managed node can determine the radio frame or superframe in which the perception signal is received or sent.
[0094] The frame period is the period of a radio frame or superframe represented by a frame number. A frame period may include multiple radio frames or superframes, and there are no specific restrictions. Combining the frame period and frame number can determine the time periods during which the perception signal is transmitted, allowing the first perception node and its controlled nodes to determine the time points at which they can receive or transmit the perception signal.
[0095] It is understandable that the transmission of the perception signal may also involve other wireless communication parameters such as frequency band and transmission power. These wireless communication parameters may be preset, or may be determined by the first management node and sent to the managed node.
[0096] Accordingly, the transmission format of the perception signal may also include one or more of the following: the frequency band for transmitting the perception signal, the transmit power, the number of antenna ports, a spatial direction selection indicator, and a duration. The frequency band refers to the bandwidth occupied by the transmission of the perception signal, the transmit power refers to the power used to transmit the perception signal, and the number of antenna ports refers to the number of antenna ports required to receive or transmit the perception signal. The spatial direction selection indicator is used to indicate the direction in which the perception signal is transmitted or received, etc. The duration is the total duration of the transmission of the perception signal.
[0097] Of course, the sending format of the perception signal may also include other wireless communication parameters according to actual needs, and there is no limitation on this.
[0098] It is understandable that if the second management node is able to participate in sensing the target object, then the second communication domain of the second management node must at least partially overlap with the sensing area of the target object, e.g., at least part of the sensing area of the target object is within the coverage of the second communication domain. Correspondingly, if the first management node is also able to perform the sensing task of the target object, then the first communication domain of the first management node must also at least partially overlap with the sensing area of the target object. Based on this, the first communication domain is a communication domain connected to the second communication domain, e.g., the first management node is a management node within the range set by the second management node.
[0099] S103: Receive or send a perception signal for perceiving a target object based on the perception configuration information configured by the managed node.
[0100] As can be seen from the previous introduction, in combination with the perception configuration information configured by the first management node for each managed node, the first management node can clearly specify information such as the specific sending method of the perception signal used to perceive the target object, thereby completing the reception or sending of the corresponding perception signal.
[0101] For example, by combining the signal type of the perception signal and the sending format of the perception signal, the first management node and each managed node can determine when and how to receive or send the perception signal, so that the first management node can transmit the perception signal between each managed node.
[0102] Whether the first management node receives or sends the perception signal is related to the perception node type configured for the first management node itself. The perception node type of the first management node can be one or both of a perception signal receiving node and a perception signal sending node.
[0103] In the present application, there is no restriction on how to determine the perception node type of the first management node and the specific implementation process of sending or receiving the perception signal.
[0104] From the above content, it can be seen that in the present application, after receiving the perception information sent by the second management node in the second communication domain, the first management node in the first communication domain can configure the perception configuration information for the managed node in the first communication domain based on the perception information, so that the managed node in the first communication domain and the first management node can receive or send the perception signal for perceiving the target object. It can be seen that if an abnormal reason occurs and the target object cannot be continued to be wirelessly perceived in the second communication domain, then after the second management node sends the perception information related to the target object to the first management node, the first management node can control the wireless perception of the target object in the first communication domain, so that the perception task of perceiving the target object can be transferred from the second communication domain to the first communication domain for execution, so as to continue the wireless perception of the target object, thereby reducing the situation where the wireless perception of the target object is interrupted due to abnormal reasons.
[0105] The wireless sensing method of the present application is introduced below from the side of the first management node of the second communication domain.
[0106] As shown in FIG2 , it shows another flow chart of the wireless sensing method provided in an embodiment of the present application. This embodiment is applied to a second management node in a wireless short-range communication system, and the second management node is in a second communication domain.
[0107] The process of this embodiment may include:
[0108] S201: Receive or send a perception signal for perceiving a target object in a second communication domain.
[0109] In the present application, there is no restriction on the specific triggering conditions and specific perception process for the second management node to perform perception of the target object.
[0110] For example, the second management node can receive a wireless sensing task issued by a user through an application, where the task is to sense a target object. Based on this task, the second management node can determine the managed nodes participating in wireless sensing within the second communication domain, configure sensing configuration information for the managed nodes, and receive or send sensing signals based on the sensing configuration information configured for the managed nodes within the second communication domain.
[0111] For another example, after obtaining the perception information sent by the management nodes in other communication domains, the second management node may also receive or send the perception signal in the manner of the embodiment of FIG. 1 .
[0112] S202: Send perception information to a first management node in a first communication domain.
[0113] The perception information is used to perceive the target object, so that the first management node perceives the target object within the first communication domain.
[0114] In the present application, there may be many possible specific circumstances for triggering the second management node to send perception information to the first management node, which can be determined in combination with the specific perception of the target object by the second management node. This application does not impose any restrictions on this.
[0115] It can be understood that, in order to enable the first management node to participate in sensing the target object, the first communication domain of the first management node overlaps with the sensing area of the target object.
[0116] Based on this, before the second management node sends the perception information to the first management node, the second management node needs to determine the first management node whose first communication domain overlaps with the perception area of the target object.
[0117] There may be many possibilities for the specific implementation of the first management node where the second management node determines that the communication domain overlaps with the perception area of the target object, and this application does not impose any limitation on this.
[0118] For example, the second management node in the wireless short-range communication system can exchange information with its adjacent neighbor management node (such as a management node within the maximum communication range of the management node, or a pre-set neighbor management node, etc.). Based on this, the second management node can determine the coverage of the communication domain of the neighbor management node, and based on the coverage of the communication domain of the neighbor management node and the perception area of the target object perceived by the second management node, determine whether the communication domain of the neighbor management node overlaps with the perception area of the target object. If so, the neighbor management node can be determined as the first management node.
[0119] Of course, if the perception task of the target object has been pre-sent to other neighbor management nodes other than the second management node, that is, although the neighbor management node is not responsible for executing the perception task, it can obtain the perception area of the target object. In this case, the second management node interacts with the neighbor management node to obtain whether the communication domain of the neighbor management node overlaps with the perception area of the target object. If so, the neighbor node is determined as the first management node.
[0120] Of course, there may be other possible ways for the second management node to determine the first management node, and this application does not impose any restrictions on this.
[0121] From the above content, it can be seen that in the process of the second management node in the second communication domain participating in the perception of the target object, the second management node can send perception information to the first management node in the first communication domain, so that the first management node can wirelessly perceive the target object in the first communication domain based on the perception information. In this way, when the second communication domain of the second management node is not suitable for continuing to wirelessly perceive the target object, the first management node of the first communication domain can be triggered to continue to perceive the target object in the first communication domain, so that the perception task of perceiving the target object can be transferred from the second communication domain to the first communication domain, reducing the situation where the wireless perception of the target object is interrupted due to special circumstances, and naturally realizing continuous perception of the target object.
[0122] It is understandable that in this application, there may be many possible situations where the target object perception task needs to be transferred from one communication domain to another. The following is an explanation of two different application scenarios.
[0123] In a first possible application scenario, during wireless sensing of a target object in the second communication domain, the target object moves from the second communication domain to the first communication domain, making the second communication domain no longer suitable for wireless sensing of the target object.
[0124] FIG3 shows an example diagram of a scenario in which wireless sensing of a sensing target is performed in an embodiment of the present application.
[0125] In the scenario of Figure 3, the target (i.e., target object) to be sensed is a user. This target has a corresponding sensing area, which is the area outlined by the dotted rectangle in the figure. A portion of this sensing area is within the communication domain A where the management node Ga (hereinafter referred to as the second management node Ga) is located, and another portion of this sensing area is within the communication domain B where the management node Gb (hereinafter referred to as the first management node Gb) is located.
[0126] Five managed nodes are shown within the communication domain A of the management node Ga. These five managed nodes are the circled nodes in communication domain A, excluding node Ga. As shown in Figure 3, the five managed nodes within communication domain A are designated Ta1, Ta2, Ta3, Ta4, and Ta5. These five managed nodes are also the managed nodes connected to the management node Ga, and can also be referred to as managed nodes connected to communication domain A. Based on this, the management node Ga can control these five managed nodes, including but not limited to obtaining information about the managed nodes, determining the managed nodes participating in wireless sensing, and configuring sensing configuration information for the managed nodes participating in wireless sensing. This will not be further described.
[0127] Similarly, in the example of five managed nodes in the communication domain B of the management node Gb, as shown in Figure 3, the five managed nodes connected to the management node Gb (the five managed nodes in the communication domain B) are represented as Tb1, Tb2, Tb3, Tb4, and Tb5 respectively.
[0128] As can be seen in Figure 3, the user being the target of perception is located within the communication domain A where the management node Ga resides. In Figure 3, wireless perception of the target is performed within the communication domain A where the management node Ga resides. In this case, the communication domain A corresponds to the second communication domain in this application, and the management node Ga is the second management node.
[0129] In this scenario, the management node Ga can receive or send a perception signal for perceiving the target object within the communication domain A. Of course, the management node Ga can also select and control at least some managed nodes within the communication domain A to participate in perceiving the perception target, thereby receiving or sending the perception signal. The details are not repeated here.
[0130] It is understandable that the sensing target can move within the sensing area. However, since the sensing area of the sensing target overlaps with both communication domain A and communication domain B, if the sensing target moves from communication domain A to communication domain B, the management node Ga and the managed nodes participating in the sensing in the communication domain cannot reliably perform wireless sensing of the sensing target.
[0131] For example, by comparing FIG3 and FIG4 , it can be seen that the perception target moves from communication domain A to communication domain B. Here, the perception target cannot be reliably perceived in communication domain A, and may even be unable to be perceived.
[0132] In this scenario, to continue wirelessly sensing the target, the user may need to reissue the target sensing task to management node Gb. However, since the user cannot promptly learn that the target has moved from communication domain A to communication domain B, this approach inevitably results in the inability to timely wirelessly sense the target within communication domain B, leading to interrupted sensing of the target. This makes it impossible to maintain continuous sensing of the target even when the pole target moves from communication domain A to communication domain B. Furthermore, the user's reconfiguration and instructing management node Gb to sense the target is complex and time-consuming, and inevitably leads to interrupted sensing of the target.
[0133] By using the solution of the present application, the management node Ga sends the sensing information to the management node Gb, which can trigger the sensing node Gb to sense the sensing target. In this scenario, the sensing information can be sensing target information, which includes: state information of the target object.
[0134] The following is an explanation with reference to the flowchart shown in FIG5. FIG5 shows a schematic diagram of a process interaction of the wireless sensing method provided by an embodiment of the present application, which can be applied to a wireless short-range communication system. This embodiment may include:
[0135] S501: A second management node receives or sends a perception signal for perceiving a target object within a second communication domain.
[0136] In the present application, there is no restriction on the specific implementation process of the second management node performing wireless perception on the target object.
[0137] For example, the second management node obtains a sensing task indication for instructing sensing of the target object, and in response to the sensing task indication, determines at least one managed node within the second communication domain that participates in sensing the target object. The second management node configures sensing configuration information for the determined managed node, and receives or sends a sensing signal based on the sensing configuration information configured for each managed node.
[0138] S502: The second management node detects that a target object enters a first communication domain of a first management node, and sends sensing target information to the first management node.
[0139] There are many possibilities for the specific implementation of the second management node detecting that the target object enters the first communication domain of the first management node, and this application does not impose any limitation on this.
[0140] The following describes several possible implementations of determining that the target object is moved to the first communication domain as an example:
[0141] In one possible implementation, the second management node identifies a first communication domain that overlaps with the target object's perception area. For example, the second management node may determine the first communication domain that overlaps with the target object's perception area and the first management node within the first communication domain by exchanging information with its neighboring management nodes, without limitation. Accordingly, after detecting that the distance between the target object's location and the boundary of the first communication domain is less than a set threshold, if it is detected that the target object has left the second communication domain, it can be determined that the target object has moved to the first communication domain.
[0142] In another possible implementation, the second management node may determine the location of the first management node and, based on this, in combination with the location of the first management node, determine that the target object has entered the first communication domain if the second management node senses that the target object is closer to the first management node.
[0143] Of course, two simple implementation methods are used as examples here. In actual applications, the second management node may also use other methods to determine whether the target object enters the first communication domain of the first management node, and there is no limitation on this.
[0144] In an embodiment, the perceived target information may include: state information of the target object. The state information of the target object may be state information of the target object perceived by the second management node, and may be state information of the target object determined by the second management node based on the perception signal or perception measurement data of the perception signal. For example, the state information of the target object may include: at least one of the position, speed, and trajectory of the target object.
[0145] In one possible implementation, when the second management node detects that the target object enters the first communication domain of the first management node, the second management node may also first send perception enabling information to the second management node in the second communication domain, and the perception enabling information is used to instruct the first management node to perceive the target object.
[0146] On this basis, after the first management node obtains the sensing enablement information, if the first management node agrees to perform wireless sensing of the target object, the first management node may send a response confirmation indication to the second management node in response to the sensing enablement information. The response confirmation indication indicates that the first management node agrees to perform sensing of the target object. Correspondingly, the second management node will send the sensing target information to the first management node only after receiving the response confirmation indication.
[0147] S503: The first management node configures awareness configuration information for the managed nodes in the first communication domain based on the state information of the target object.
[0148] The perception configuration information is some configuration information required for the managed node to participate in perceiving the target object, as described above, and will not be repeated here.
[0149] It is understandable that not every managed node in the first communication domain is suitable for participating in perceiving the target object. Based on this, in order to more reasonably determine the managed nodes in the first communication domain that are suitable for participating in perceiving the target object, the present application may also combine the status information of the target object to determine at least one managed node in the first communication domain that participates in perceiving the target object, and then configure perception configuration information for each determined managed node.
[0150] For example, the first management node can obtain the location and perception capabilities of each managed node, and combine the location of the target object, as well as the location and perception capabilities of each managed node, to determine at least one managed node whose distance to the target object is less than a set threshold and whose perception capability has the ability to perceive the target object.
[0151] It can be understood that determining the managed nodes participating in perceiving the target object in combination with the status information of the target object is only one implementation method. In actual applications, the first management node can also determine at least one management node participating in perceiving the target object based solely on the perception capabilities of the managed nodes, without any restrictions.
[0152] It is understandable that the perception task of perceiving the target object may also include a perception quality requirement for perceiving the target object, such as the position accuracy and velocity accuracy of the target object, which are not limited.
[0153] It is understandable that if the perception task is sent to the first management node when it is sent to the second management node, the first management node may store the perception quality requirement of the target object.
[0154] In particular, if the first management node does not have the perceptual quality requirement of the target object, the first management node may further request the perceptual quality requirement of the target object from the second management node, and obtain the perceptual quality requirement of the target object returned by the second management node.
[0155] Based on the above, the first management node may further determine at least one managed node that participates in perceiving the target object based on the perception quality requirement of the target object. For example, the at least one managed node that participates in perceiving the target object may be determined based on the perception quality requirement and the perception capabilities of each managed node in the first communication domain.
[0156] In practical applications, the first management node may further determine the managed nodes that participate in perceiving the target object from within the first communication domain in combination with the state information and the perception quality requirement of the target object, which will not be described in detail.
[0157] S504: The first management node receives or sends a perception signal for perceiving the target object based on the perception configuration information configured by the managed node in the first communication domain.
[0158] For example, after determining the managed nodes that participate in perceiving the target object, the first management node configures perception configuration information for the determined managed nodes. Based on the perception configuration information configured by the first management node for each determined managed node, the first management node can clearly identify the wireless frames that need to receive or send perception signals within each wireless frame period within the first communication domain, so that the perception signals can be received or sent within the corresponding wireless frames according to the sending format of the relevant perception signals.
[0159] Of course, based on receiving or sending the perception signal, the first management node may also obtain the perception measurement data corresponding to the perception signal sent by the managed node to determine the perception measurement result of the target object, and there is no restriction on this.
[0160] As can be seen from the flowchart of Figure 5, after the target object of wireless perception moves from the second communication domain to the first communication domain, the second management node of the second communication domain can send the status information of the target object to the first management node of the first communication domain. On this basis, the first management node in the first communication domain can configure perception configuration information for the managed nodes in the first communication domain based on the status information of the target object, and perform wireless perception of the target object in the first communication domain. In this way, when the target object moves from the second communication domain to the first communication domain, the target object can continue to be wirelessly perceived in the first communication domain, reducing the situation where the wireless perception of the target object is interrupted due to the target object moving out of the communication domain that currently perceives the target object.
[0161] It is understandable that after the first management node takes over the task of sensing the target object, if the second management node in the second communication domain or the managed node in the second communication domain still maintains relevant resources for sensing the target object, it may cause resource waste.
[0162] Based on this, in the first application scenario, after the first management node configures the perception configuration information for the managed node in the second communication domain, or after the first management node receives or sends a perception signal, the first management node can also send a perception task confirmation indication to the second management node. The perception task confirmation indication is used to indicate that the first management node has completed the configuration of the perception configuration information.
[0163] Correspondingly, after the second management node obtains the sensing task confirmation indication, the second management node may release the sensing resources used for sensing the target object in the second communication domain in response to the sensing task confirmation indication.
[0164] For example, the second management node stops receiving and sending the sensing signal for sensing the target object. The second management node may also instruct the managed nodes participating in sensing the target object in the second communication domain to stop sensing the target object.
[0165] For ease of understanding, the process interaction process in the first scenario is described using a specific implementation as an example, with the management node being the G node and the managed node being the T node, in conjunction with the scenario examples in Figures 3 and 4. As shown in Figure 6, it shows another process interaction diagram of the wireless sensing method provided in an embodiment of the present application. The method of this embodiment can be applied to a wireless short-range communication system.
[0166] The method of this embodiment may include:
[0167] S601: The second management node Ga receives or sends a perception signal with each managed node participating in perceiving a target object within the communication domain A.
[0168] For ease of understanding, Figure 6 uses the scenarios of Figures 3 and 4 as examples. As can be seen from Figures 3 and 4, the second management node is management node Ga, and its second communication domain is communication domain A. Correspondingly, the first management node is management node Gb, and its first communication domain is communication domain B.
[0169] As shown in Figure 6, taking the managed node as node T as an example, and since Figure 6 takes the scenarios of Figures 3 and 4 as examples, the managed node participating in perception in communication domain A can be node Tax, and Tax can be any one of the managed nodes Ta1, Ta2, Ta3, Ta4 and Ta5.
[0170] S602: The second management node Ga detects that the target object enters the communication domain B of the first management node Gb, and sends sensing enabling information to the first management node Gb.
[0171] The sensing enabling information is used to instruct the first management node Gb to sense the target object.
[0172] S603: The first management node Gb sends a response confirmation indication to the second management node Ga in response to the sensing enable information.
[0173] The response confirmation indication indicates that the first management node Gb agrees to perceive the target object.
[0174] S604: The second management node Ga sends the sensing target information to the first management node Gb in response to the response confirmation indication.
[0175] The sensed target information includes: state information of the target object. For example, the state information of the target object may include information such as the position, speed, and trajectory of the target object.
[0176] In an optional manner, the second management node Ga may also send the perceived quality requirement of the target object to the first management node Gb.
[0177] Of course, the second management node may also return the perceptual quality requirement of the target object to the first management node after obtaining the request sent by the first management node for requesting the perceptual quality requirement of the target object.
[0178] S605: The first management node Gb requests each managed node in the communication domain B for sensing capability and location information.
[0179] As shown in FIG6 , the first management node Gb instructs the managed node Tbx in the communication domain B to report the sensing capability and location information. In step S605 , Tbx may be the managed nodes Tb1 , Tb2 , Tb3 , Tb4 and Tb5 in the communication domain B in FIG4 .
[0180] S606: The first management node Gb obtains the sensing capability and location information reported by the managed nodes in the communication domain B.
[0181] S607, the first management node Gb determines the managed nodes participating in perception from within the communication domain B based on the status information of the target object, the perception capabilities and location information of each managed node within the communication domain B, and configures perception configuration information for the determined managed nodes.
[0182] The first management node may determine the required perception configuration information for the managed node using any currently available method, without limitation. In an optional embodiment, to more effectively perceive the target object, the first management node may further configure the perception configuration information for the determined managed node in conjunction with the target object's status information.
[0183] S608: The first management node Gb sends a sensing task confirmation indication to the second management node Ga.
[0184] The perception task confirmation indication is used to indicate that the first management node has completed the configuration of the perception configuration information.
[0185] S609: The first management node Gb receives or sends a perception signal between the first management node and the managed node in the communication domain B based on the perception configuration information configured by the managed node in the communication domain B.
[0186] It should be noted that the order of steps S608 and S609 is not limited to that shown in FIG6 . In practical applications, the order of steps S608 and S609 can be interchanged or performed simultaneously, and there is no limitation on this.
[0187] S610: The second management node Ga releases resources in the communication domain A used for sensing the target object in response to the sensing task confirmation indication.
[0188] In the second possible application scenario, considering the mobility of managed nodes within a communication domain due to the development of short-range wireless communication technologies, if a management node identifies a managed node as a managed node that participates in sensing a target object and senses the target object within the management node's communication domain, the managed node participating in sensing may move from that communication domain to another.
[0189] If all managed nodes participating in perception within a communication domain move, or if there is only one managed node participating in perception within a communication domain, then the movement of the managed node from the communication domain to another communication domain will inevitably cause the communication domain to be unable to continue wirelessly perceiving the target object, thereby interrupting the perception of the target object.
[0190] FIG. 7 shows an example scenario where a managed node moves from one communication domain to another communication domain in the scenario shown in FIG. 3 .
[0191] As can be seen from Figure 3, the managed node Ta1 is originally located in communication domain A and is connected to the management node Ga. Moreover, in the example scenario of Figure 3, wireless sensing of the sensing target is performed within communication domain A, and the managed node Ta1 is a managed node within communication domain A that participates in sensing the sensing target.
[0192] Comparing FIG3 and FIG7 , it can be seen that in the example scenario of FIG7 , the managed node Ta1 moves from the communication domain A to the communication domain B where the management node Gb is located.
[0193] It is understandable that if the only managed node currently participating in perception in communication domain A is managed node Ta1, then after Ta1 moves from communication domain A to communication domain B, the management node Ga will not be able to continue to perform wireless perception of the perception target in communication domain A, which will cause perception of the perception target to be interrupted.
[0194] Similarly, if there are multiple managed nodes participating in sensing the sensing target in communication domain A, but these multiple managed nodes are all moved to communication domain B, then the management node Ga is also unable to continue sensing the sensing target.
[0195] In the example scenarios of Figures 3 and 7 , communication domain A is equivalent to the second communication domain, and management node Ga in communication domain A is equivalent to the second management node. Communication domain B is equivalent to the first communication domain, and management node Gb in communication domain B is equivalent to the first management node.
[0196] In the present application, in order to reduce the risk of perception interruption of the target object (i.e., the perception target), when the target managed node (such as Ta1 in Figure 7) participating in perceiving the target object moves from the second communication domain to the first communication domain, the present application can send the historical perception configuration information of the target managed node to the first management node in the first communication domain through the second management node in the second communication domain, so that the first management node in the first communication domain can reconfigure the perception configuration information for the target managed node in the first communication domain based on the historical perception configuration information of the target managed node, so that the first management node and the target managed node can perform wireless perception of the target object in the first communication domain to reduce the risk of wireless perception of the target object being interrupted.
[0197] The second application scenario is described below in conjunction with the flowchart of Figure 8. As shown in Figure 8, another flowchart of the wireless sensing method provided by an embodiment of the present application is shown. This embodiment may include:
[0198] S801: A second management node receives or sends a perception signal for perceiving a target object within a second communication domain.
[0199] For example, the second management node may send a perception signal to the managed nodes participating in perceiving the target object in the second communication domain, or receive a perception signal sent by the managed nodes participating in perceiving the target object in the second communication domain.
[0200] For example, as can be seen from FIG3 , the management node Ga can transmit a sensing signal for sensing the sensing target to the managed node Ta1 , so as to achieve wireless sensing of the sensing target.
[0201] S802: The second management node detects that the link quality between the target managed node and the first management node in the first communication domain is better than the link quality between the target managed node and the second management node, and sends history awareness configuration information to the first management node.
[0202] The target managed node is a managed node that participates in sensing the target object in the second communication domain. The historical sensing configuration information is sensing configuration information configured by the second management node for the target managed node and is used to sense the target object.
[0203] The historical perception configuration information may also include the signal type of the perception signal received or sent by the target managed node and the sending format of the perception signal, etc. For details, please refer to the previous introduction and will not be repeated here.
[0204] It is understandable that there may be multiple ways for the second management node to determine the link quality between the target managed node and the first management node and the second management node, and this application does not impose any limitation on this.
[0205] For example, in one possible implementation, each management node in a wireless short-range communication system can periodically or irregularly broadcast a communication reference signal for measuring signal instructions. Based on this, managed nodes within a communication domain can receive not only the communication reference signal sent by the management node within that communication domain, but also the communication reference signals sent by other management nodes.
[0206] For a communication reference signal from any management node, the managed node determines a signal quality measurement result based on the received communication reference signal. This signal quality measurement result indicates the signal quality between the managed node and the managed node. In response, the managed node sends the signal quality measurement results between the managed node and each management node to the management nodes within the managed node's communication domain.
[0207] Accordingly, the management node may determine the link quality between the managed node and each managed node based on the signal quality measurement results between the managed node and each management node sent by the managed node in the communication domain.
[0208] Based on this, the second management node can determine the link quality between the target managed node and the first management node and the link quality between the target managed node and the second management node based on the signal quality measurement results of the target managed node and the first management node sent by the target managed node and the signal quality measurement results of the target managed node and the second management node, and then determine whether the link quality between the target managed node and the first management node is due to the link quality between the target managed node and the second management node.
[0209] Of course, the second management node may also determine the link qualities between the target managed node and the first managed node and the second managed node respectively in other ways, and there is no limitation to this.
[0210] It can be understood that if the link quality between the target managed node and the first management node is better than the link quality between the target managed node and the second management node, the target managed node is closer to the first management node, which means that the target managed node has moved from the second communication domain of the second management node to the first communication domain of the first management node.
[0211] Similar to the first scenario above, in order to enable the first management node to participate in sensing the target object, the first communication domain of the first management node in this application must also at least partially overlap with the sensing area of the target object.
[0212] In this embodiment, the second management node can interact with its neighboring management nodes to determine, from the neighboring management nodes, a first management node whose first communication domain overlaps with the perception area of the target object. This is not further described here. Based on this, if the second management node determines that the link quality between the target managed node, which is connected to the second management node and participating in perceiving the target object, and the first management node is superior, the second management node can send the historical perception configuration information of the target managed node to the first management node.
[0213] S803: The first management node configures awareness configuration information for a target managed node in the first communication domain based on the historical awareness configuration information.
[0214] As previously explained, when the first management node receives the historical awareness configuration information of the target managed node from the second management node, it indicates that the target managed node has entered the first communication domain of the first management node from the second communication domain. Based on this, the first management node understands that the target managed node is a managed node that has historically connected to the second management node in the second communication domain and participated in awareness of the target object.
[0215] It is understood that after the target management node enters the first communication domain of the first management node, the target managed node is qualified to be a managed node within the first communication domain. Based on this, in order for the first management node to continue wirelessly sensing the target object within the first communication domain using the target managed node, the first management node needs to configure sensing configuration information for the target managed node.
[0216] It can be understood that in order to enable the target managed node to switch more quickly to wireless perception of the target object within the first communication domain and ensure the reliability of continued perception of the target object, this application will combine the historical perception configuration information of the target managed node to update the perception configuration information of the target managed node within the first communication domain.
[0217] For example, the historical perception configuration information of the target managed node is still applicable to the perception of the target object in the first communication domain, and the historical perception configuration information can be directly determined as the perception configuration information of the target managed node in the first communication domain.
[0218] For example, the historical perception configuration information of the target managed node, the perception capability of the first management node, etc. can be combined to appropriately adjust the historical perception configuration information of the target managed node to obtain updated perception configuration information of the target managed node.
[0219] In this embodiment, there is no restriction on how to determine the awareness configuration information of the target managed node in the first communication domain.
[0220] It is understandable that there may be one or more target managed nodes entering the first communication domain of the first management node, but the perception configuration information may be configured for each target managed node in the above manner, which will not be elaborated herein.
[0221] It is understandable that if the first management node can use the target managed node as a managed node that participates in perceiving the target object within the first communication domain, it means that the target managed node is currently connected to the first management node and belongs to the managed node within the first communication domain.
[0222] For example, the target managed node can receive the communication reference signal sent by the first management node and the communication reference signal sent by the second management node. When it is determined that the signal quality of the communication reference signal of the first management node is better, it can apply for access to the first management node.
[0223] For another example, when the second management node detects that the link quality between the target managed node and the first management node is better than the link quality between the target managed node and the second management node, the second management node may send a new domain access indication to the target managed node, where the new domain access indication is used to instruct the target managed node to access the first management node in the first communication domain.
[0224] Accordingly, in response to the new domain access indication, the target managed node may send a node access request to the first management node, where the node access request is used to request access to the first management node as a perception participating node of the target object. Upon receiving the node access request sent by the target managed node, the first management node may determine that the target managed node is a managed node within the first communication domain and is a managed node that participates in the perception of the target object.
[0225] Of course, after the first management node detects the node access request sent by the target managed node, the first management node may also determine whether the target managed node meets the access conditions for accessing the first management node according to the configured node access rules. If the access conditions are met, the target managed node may be connected to the first communication domain. This application does not limit the specific method for determining whether the target managed node meets the access conditions.
[0226] Furthermore, in order to enable the second management node to know that the first management node has currently designated the target managed node as a participating perception target managed node in the first communication domain, the first management node may further, upon confirming that the target managed node has successfully connected to the first management node, send an access success indication to the second management node. The access success indication indicates that the target managed node has connected to the first management node.
[0227] Correspondingly, the second management node may send the history awareness configuration information of the target managed node to the first management node after obtaining the access success indication.
[0228] S804: The first management node receives or sends a perception signal for perceiving a target object based on the perception configuration information configured for the target managed node.
[0229] It can be understood that, in this embodiment, the first management node may only use the target managed node as a managed node that participates in sensing the target object within the first communication domain.
[0230] The first management node may also determine other managed nodes within the first communication domain that participate in perceiving the target object, provided that the target managed node is used as the managed node participating in perceiving the target object within the first communication domain. For other managed nodes within the first communication domain that participate in perceiving the target object, in addition to the target managed node, the first management node will also configure perception configuration information for these managed nodes. The specific process is not limited.
[0231] It can be seen from this embodiment that when the second management node detects that the link quality between the target managed node participating in sensing the target object in its second communication domain and the first management node is better, the second management node can confirm that the target managed node has moved to the first communication domain of the first management node. On this basis, the second management node will send the historical perception configuration information of the target managed node to the first management node. After the first management node receives the historical perception configuration information of the target managed node, the first management node can configure the perception configuration information for the target managed node in the first communication domain, so that the first management node and the target managed node can continue to wirelessly perceive the target object in the first communication domain, thereby avoiding the situation where the target managed node cannot continue to perceive the target object due to the target managed node moving from the second communication domain to the first communication domain, and naturally reducing the situation where the perception of the target object is interrupted.
[0232] It is understood that in the second application scenario, in order to enable the target managed node to promptly perceive the target object within the first communication domain, that is, to enable the first communication domain to relatively quickly assume the responsibility for perceiving the target object, the target managed node may also proactively include information related to the perception of the target object, such as the target managed node's perception capabilities, when initiating a node access request to the first management node. Accordingly, the first management node may also configure perception configuration information for the target managed node, combining information such as the target managed node's perception capabilities with the historical perception configuration information.
[0233] To facilitate understanding of the second application scenario, the management node is taken as the G node and the managed node is taken as the T node. Combined with the scenario examples of Figures 3 and 7, the process interaction process of the wireless sensing method involved in the second scenario is explained using a specific implementation as an example.
[0234] As shown in Figure 9, it shows another flow diagram of the wireless sensing method provided in the embodiment of the present application in the second application scenario. The method of this embodiment can be applied to a wireless short-range communication system.
[0235] The method of this embodiment may include:
[0236] S901: The second management node Ga receives or sends a perception signal for perceiving a target object within a communication domain A.
[0237] In this embodiment, the communication domain A is the second communication domain where the second management node is located. The target object is the sensing target in FIG3 and FIG7 .
[0238] S902: The managed node Ta1 obtains a communication reference signal sent by the second management node Ga, and determines a first signal quality measurement result between the managed node Ta1 and the second management node Ga.
[0239] The first signal quality measurement result is determined by the managed node Ta1 based on the communication reference signal from the second management node, and represents the signal quality between the managed node Ta1 and the second management node Ga.
[0240] S903: The managed node Ta1 obtains a communication reference signal sent by the first management node Gb in the communication domain B, and determines a second signal quality measurement result between the managed node and the first management node Gb.
[0241] The second signal quality measurement result is determined by the managed node Ta1 based on the communication reference signal from the first management node Gb, and represents the signal quality between the managed node Ta1 and the first management node Gb.
[0242] S904: The managed node Ta1 sends the first signal quality measurement result and the second signal quality measurement result to the second management node Ga.
[0243] This embodiment uses the scenarios shown in Figures 3 and 7 as examples. Assume that in the application scenario shown in Figure 3, the managed node participating in wireless sensing in the communication domain A of the second management node Ga is the managed node Ta1. In step S904 above, the management node accessed by the managed node Ta1 is the second management node Ga. Therefore, the managed node Ta1 needs to send the measured signal quality results to the second management node Ga.
[0244] S905 , the second management node Ga determines, based on the first signal quality measurement result and the second signal quality measurement result, that the link quality between the managed node Ta1 and the first management node Gb is better than the link quality between the managed node Ta1 and the second management node Ga, and sends a new domain access indication to the managed node Ta1.
[0245] For example, if the signal quality represented by the first signal quality measurement result is better than the signal quality represented by the second signal quality measurement result, it can be determined that the link quality between the managed node Ta1 and the first management node Ga is better than the link quality between the managed node Ta1 and the second management node Ga.
[0246] The new domain access indication is used to instruct the managed node Ta1 to access the first management node Gb in the communication domain B.
[0247] In an optional manner, before step S905 , the second management node Ga has determined that the communication domain B of the first management node Gb overlaps with the perception area of the target object.
[0248] Of course, the second management node may not care whether the communication domain B overlaps with the perception area of the target object and only needs to operate according to this embodiment. Only when the communication domain B overlaps with the perception area of the target object will the first management node Gb in the communication domain B return an access success indication to the second management node Ga.
[0249] It is understood that in this embodiment, using the scenarios shown in Figures 3 and 7 as examples, the link quality between managed node Ta1 and first management node Gb in Figure 3 is superior, indicating that managed node Ta1 has moved to communication domain B of first management node Gb. However, since there are no other managed nodes participating in wireless sensing within communication domain A, wireless sensing of the sensing target can no longer be performed within communication domain A. Therefore, managed node Ta1 is the target managed node.
[0250] Correspondingly, the second management node Ga determines that the link quality between the managed node Ta1 and the first management node Gb is better than the link quality between the managed node Ta1 and the second management node Ga, and then determines the managed node Ta1 as the target managed node and sends a new domain access indication to it.
[0251] It should be noted that this embodiment is illustrated by taking an implementation method in which the second management node determines that the link quality between the target managed node (managed node Ta1) and the first management node is better than the link quality between the target managed node and the second management node. In actual applications, determining the link quality between the target managed node and the first management node and the second management node by other methods is also applicable to this embodiment and is not limited to this.
[0252] S906: The managed node Ta1 sends a node access request to the first management node Gb in the communication domain B.
[0253] The node access request node is used to request the perception participating node as the target object to access the first management node.
[0254] It is understandable that, in order for the first management node to know the management node to which the managed node Ta1 is currently connected, the node access request may further indicate the second management node Ga to which the managed node Ta1 currently belongs. For example, the node access request may include information such as the identifier or address of the second management node Ga.
[0255] Furthermore, the node access request may also indicate the awareness capability of the managed node Ta1.
[0256] As an optional approach, to enable the first management node to promptly learn the target objects that the managed node Ta1 participates in sensing, the node access request may further indicate the target objects that the managed node Ta1 (i.e., the target managed node) participates in sensing. For example, the node access request may further include some or all of the target object's information, such as its name and location, without limitation.
[0257] S907 , when confirming that the managed node Ta1 has successfully accessed the first management node Gb, the first management node Gb sends an access success indication to the second management node Ga.
[0258] The access success indication indicates that the managed node Ta1 (ie, the target managed node) has successfully accessed the first management node.
[0259] S908: The second management node Ga detects the access success indication and sends history awareness configuration information to the first management node Gb.
[0260] The historical perception configuration information is the perception information configured by the first management node Ga for the managed node Ta1 and is used to perceive the target object. The details are as described above and will not be repeated here.
[0261] S909 : The first management node Gb configures sensing configuration information within the communication domain B for the managed node Ta1 based on the sensing capability and historical sensing configuration information of the managed node Ta1 .
[0262] For example, based on the perception capability of the managed node Ta1 and the specific perception capability of the first management node, the historical perception configuration information of the managed node Ta1 is updated to obtain the perception configuration information of the managed node Ta1 perceiving the target object in the communication domain B.
[0263] Similar to the previous embodiment, in an optional manner, the first management node may also obtain the perceptual quality requirement of the target object. For a specific obtaining method, please refer to the relevant introduction in the first application scenario above, which will not be repeated here.
[0264] Accordingly, the first management node may further configure the managed node Ta1 with perception configuration information for perceiving the target object in the communication domain B based on the perception quality requirement, the perception capability of the managed node Ta1 and historical perception configuration information.
[0265] S910: The first management node Gb receives or sends a sensing signal for sensing the target object based on the sensing configuration information configured by the managed node Ta1.
[0266] Correspondingly, the managed node Ta1 will also receive or send a perception signal for perceiving the target object within the first communication domain according to the perception configuration information configured for it by the first management node.
[0267] In combination with Figures 3 and 7, it can be seen that in an embodiment of the present application, after the managed node Ta1 participating in sensing the target object in communication domain A moves to communication domain B, communication domain A can determine that the managed node Ta1 has entered communication domain B through the signal quality measurement results reported by the managed node Ta1 and the management node Ga and the management node Gb respectively. On this basis, the management node Ga of communication domain A will instruct the managed node Ta1 to access the management node Gb in communication domain B as a perception node participating in sensing the target object.
[0268] After the management node Gb confirms that the managed node has successfully accessed the communication domain B as a perception node, it will send a successful access indication to the management node Ga, so that the management node Ga will send the historical perception configuration information of the managed node Ta1 to the management node Gb, so that the management node Gb can use the historical perception configuration information as a reference to configure the perception configuration information for the managed node Ta1. Naturally, the managed node Ta1 and the management node Gb can continue to wirelessly perceive the target object in the communication domain B, reducing the situation where the target object cannot be perceived due to the managed node moving out of the communication domain of the perceived target object.
