[0140] In order to support the integrated functional design of perception and communication, the network system considers introducing the perception function (SF) in the core network of the network system. The perception function can be understood as a perception network element. The perception function or perception network element is used to support the processing of perception tasks, including perception service control, perception measurement data reporting and other processes. The perception function is a network element or network function with the functions of perception decision-making, perception data processing and perception result opening. The perception function includes the control plane perception function (SF-C, Sensing Function Control Plane) and the user plane perception function (SF-U, Sensing Function User Plane).

[0141] At present, when using base stations to complete perception tasks, for example, using the method of base station A sending and base station B receiving can reduce the requirements for full-duplex perception of the radio access network (RAN). The transceiver in the perception node is isolated in space, which can avoid the self-interference problem in the self-transmission and self-reception of a single perception node, and reduce the requirements for the hardware self-interference elimination capability. However, in the current scenario of cooperative perception based on RAN perception nodes and / or network nodes, there is no clear configuration of the interaction mechanism between the perception nodes and / or network nodes and the core network. For example, for the user equipment (UE) self-transmission and self-reception, and / or, the mode of UEA sending and UEB receiving, the UE can be understood as a terminal, and there is no clear configuration of the interaction mechanism between the core network and the perception node UE (UE-based); and for the scenario where the perception target needs to be continuously tracked, it is impossible to continuously track the perception target, resulting in the inability to ensure the continuity of the perception service, and there is a problem of weak collaborative perception capability.

[0142] Based on this, in various embodiments of the present application, on the one hand, in the process of sensing the movement of the target, after receiving the sensing request, the first network function can update the sensing node according to the capability information of the network node and / or the demand information of the sensing request, so as to use the appropriate sensing node to collaboratively sense the sensing target, which can not only ensure the continuity of the sensing service, but also continuously track the sensing target, thereby improving the collaborative sensing capability. On the other hand, when the first network function receives multiple sensing requests, it can merge the sensing requests with the same sensing target and / or the same sensing area in the multiple sensing requests, without repeatedly executing the sensing requests with the same sensing target and / or the same sensing area, so as to save resource overhead, which can improve both the sensing efficiency and the sensing resource utilization.

[0143] The present application is further described in detail below in conjunction with the accompanying drawings and embodiments.

[0144] The embodiment of the present application provides a communication perception method, which is applied to a first network function, and the first network function may include one or more of the following: SF-C, SF, and data plane control function. Figure 1 As shown, the method includes:

[0145] Step 101: Receive a sensing request.

[0146] Here, the perception request can be understood as a perception service request, and the perception request can carry demand information. For example, the perception request includes the location information of the perception target and the perception task type. The initiator of the perception request can be an application function (AF), such as an external AF or a third-party AF, or a network function (NF), such as an internal NF, or a UE, without specific limitation. The number of perception requests is not limited.

[0147] In one embodiment, the receiving the sensing request includes:

[0148] A sensing request sent by a third network function is received.

[0149] Here, the third network function includes an access and mobility management function (AMF, Access and MobilityManagement Function), and / or other control functions. In actual applications, the initiator of the perception request can directly or indirectly send a perception request to the third network function, and the third network function forwards the received perception request to the first network function. For example, the external AF sends a perception request to the third network function through the network exposure function (NEF, Network Exposure Function), and the internal NF triggers the perception request and directly sends the perception request triggered by the internal NF to the third network function. The UE sends a perception request to the third network function through a network device or RAN. The network device includes a base station and / or an access network device. The base station can be gNB, RAN-based.

[0150] It should be understood that the third network function may select SF and / or SF-C according to the received perception request and the capabilities supported by the SF and / or SF-C, and send the perception request to the selected first network function.

[0151] In this embodiment, the sensing request sent by the third network function is explicitly received, so as to trigger the determination or update of the sensing node when the sensing request is received.

[0152] Step 102: Determine or update one or more sensing nodes in the network node based at least on the capability information of the network node and / or the requirement information of the sensing request.

[0153] Here, one or more perception nodes are determined or updated in the network node at least based on the capability information of the network node and / or the requirement information of the perception request. It can be that one or more perception nodes are determined or updated in the network node at least based on the capability information of the network node, or it can be that one or more perception nodes are determined or updated in the network node at least based on the requirement information of the perception request, or it can be that one or more perception nodes are determined or updated in the network node at least based on the capability information of the network node and the requirement information of the perception request. In actual applications, the first network function determines or updates one or more perception nodes in the network node based on the requirement information of the perception request, the capability information of the network node, and the network topology information. Among them, the network node includes a network device and / or a UE. The requirement information of the perception request may include the perception service requirement carried by the perception request and / or the perception business requirement carried by the perception request.

[0154] In one embodiment, the demand information includes at least one or more of the following:

[0155] Perceive QoS requirement information;

[0156] Perception area;

[0157] Sense the location information of the target.

[0158] Here, the perceived QoS requirement information includes at least one or more of the following: perceived delay requirement, perceived accuracy requirement, confidence, resolution, refresh rate, missed detection rate, false alarm rate, and data update frequency.

[0159] The perception area can be understood as the perception capability area, the area where the perception target is located, or the area that the perception target may reach or pass through.

[0160] Determine or update one or more perception nodes in the network node based on the demand information of the perception request. For example, determine or update one or more perception nodes in the network node based on the perception QoS demand information, which may be to determine one or more network nodes that meet the perception QoS demand information as perception nodes or as new perception nodes; determine or update one or more perception nodes in the network node based on the perception area, which may be to determine one or more network nodes whose communication range covers the perception area as perception nodes or as new perception nodes; determine or update one or more perception nodes in the network node based on the location information of the perception target, which may be to determine one or more network nodes within a certain range centered on the location information of the perception target as perception nodes or as new perception nodes.

[0161] In this embodiment, the content included in the demand information of the perception request is clarified to facilitate determining or updating one or more perception nodes in the network node.

[0162] In one embodiment, updating one or more sensing nodes based at least on the capability information of the network node and / or the requirement information of the sensing request includes:

[0163] When one or more of the following conditions are met, one or more sensing nodes are updated based at least on the capability information of the network node and / or the requirement information of the sensing request:

[0164] The sensing node cannot continue to perform the sensing task;

[0165] The sensing node used to receive the echo signal cannot receive the echo signal;

[0166] The sensing node used to send the sensing signal cannot continue sensing;

[0167] The sensing result cannot meet the sensing QoS requirement and / or the sensing accuracy requirement of the sensing request.

[0168] Here, the inability of the sensing node to continue to perform the sensing task indicates that the sensing node no longer undertakes the sensing task due to energy consumption and / or other willingness. Specifically, it can be determined that the sensing node cannot continue to perform the sensing task based on the movement of the sensing target, or it can be determined that the sensing node cannot continue to perform the sensing task based on the movement of the sensing node.

[0169] Taking continuous sensing of a sensing target as an example, the sensing target is initially detected by base station A and base station B through cooperative sensing. The initial cooperative sensing diagram is as follows: Figure 2 As shown in the figure, base station A is a sensing node that sends sensing signals, and base station B is a sensing node that receives echo signals. The base stations (base station A and base station B) interact with the core network. At this time, base station A and base station B constitute collaborative sensing nodes. The echo signal is obtained after the sensing signal is reflected by the sensing target.

[0170] For example, Figure 3As shown, due to the movement of the sensing target, base station A is affected by the distance and / or occlusion, and the sensing signal sent by base station A cannot be received. One or more of the following information is reported directly or indirectly to the first network function: the sensing node cannot continue to perform the sensing task, the sensing node for receiving the echo signal cannot receive the echo signal, the sensing node for sending the sensing signal cannot continue to sense, the sensing result cannot meet the sensing QoS requirement of the sensing request, and the sensing result cannot meet the sensing accuracy requirement of the sensing request. The first network function updates the sensing node from base station A to base station C, that is, the sensing signal sent by base station A is switched to the sensing signal sent by base station C. At this time, base station C is the updated sensing node for sending the sensing signal; base station B is the sensing node for receiving the echo signal, and the base stations (base station A, base station B and base station C) interact with the core network, and base station C and base station B constitute a new collaborative sensing node. It is worth noting that when the sensing signal is switched from base station A to base station C, the first network function needs to reconfigure the first information of base station C.

[0171] For example, Figure 4 As shown, due to the movement of the sensing target, base station B is affected by the distance and / or occlusion, and base station B cannot continue to receive the echo signal, and directly or indirectly reports one or more of the following information to the first network function: the sensing node cannot continue to perform the sensing task, the sensing node for receiving the echo signal cannot receive the echo signal, the sensing result cannot meet the sensing QoS requirement of the sensing request, and the sensing result cannot meet the sensing accuracy requirement of the sensing request. The first network function updates the sensing node from base station B to base station D, that is, the echo signal is received by base station B and switched to the echo signal is received by base station D. At this time, base station D is the updated sensing node for receiving the echo signal; base station A is the sensing node for sending the sensing signal, and the base stations (base station A, base station B and base station D) interact with the core network, and base station A and base station D constitute a new collaborative sensing node. It is worth noting that when switching from base station B to base station D to receive the echo signal, the first network function needs to reconfigure the data transmission tunnel and first information of base station D, and configure part or all of the first information of base station A, such as configuring the new collaborative sensing node of base station A to be base station D.

[0172] It should be noted that when the base station obtains the perceived QoS requirement and / or the perceived accuracy requirement of the perception request, the base station can report to the first network function directly or indirectly (for example, through the second network function) that the perception result cannot meet the perceived QoS requirement and / or the perceived accuracy requirement of the perception request, and when the perception result cannot meet the perceived QoS requirement and / or the perceived accuracy requirement of the perception request, the perception node is updated.

[0173] In this embodiment, the conditions that need to be met for updating one or more perception nodes are clarified, which can ensure that the perception target is continuously tracked when the perception nodes are used to collaboratively complete the perception task, thereby improving the collaborative perception capability.

[0174] Step 103: Send first information to the one or more sensing nodes.

[0175] The first information is used to instruct the corresponding perception node to perform a perception task.

[0176] Here, the first information is determined based on the perception request. The first network function configures the first information corresponding to each perception node based on the received perception request, and sends the corresponding first information to each perception node; the first information of different perception nodes may be completely or partially the same, or completely different.

[0177] In this embodiment, the perception node is determined by considering the network node's perception processing capability information and the perception request requirement information. When the perception node's processing capability is insufficient, it can collaborate with other network nodes to complete the perception task, thereby being able to meet the communication perception capability integration service of more scenarios.

[0178] In one embodiment, the first information includes one or more of the following:

[0179] a sensing mode, wherein the sensing mode indicates a collaborative sensing mode or an independent sensing mode;

[0180] second information, where the second information instructs the sensing node used to send the sensing signal to send information related to the sensing signal to the second network function or the sensing node used to receive the echo signal;

[0181] third information, wherein the third information instructs the sensing node for receiving the echo signal to process the sensing data;

[0182] Fourth information, the fourth information instructing the first sensing node to send sensing data to the second sensing node, the first sensing node representing the sensing node for receiving the echo signal before the update, and the second sensing node representing the sensing node for receiving the echo signal after the update;

[0183] Information of the sensing node used to send the sensing signal;

[0184] Information of the sensing node used to receive the echo signal.

[0185] Here, the sensing mode indicates a collaborative sensing mode or an independent sensing mode. The collaborative sensing mode is an A-transmitting and B-receiving mode, for example, base station A transmits and base station B receives; the independent sensing mode is a spontaneous transmission and reception mode, for example, UE transmits and receives spontaneously.

[0186] In the case of collaborative perception, the first information of the perception node used to send the perception signal may include one or more of the following: perception method, second information, third information and information of the perception node used to receive the echo signal; the first information of the perception node used to receive the echo signal may include one or more of the following: perception method, third information, fourth information and information of the perception node used to send the perception signal.

[0187] In the case of independent perception, the first information of the independent sensing node may include one or more of the following: sensing method, second information, third information, fourth information, information of the sensing node used to send the sensing signal, and information of the sensing node used to receive the echo signal.

[0188] Considering that the sensing node for receiving the echo signal may need to refer to or process the sensing data based on the information related to the sensing signal to obtain the sensing result, therefore, when the sensing node receiving the echo signal is responsible for processing the sensing data, the first information of the sensing node for sending the sensing signal includes the second information and the third information, and the second information indicates that the sensing node for sending the sensing signal sends the information related to the sensing signal to the sensing node for receiving the echo signal. If the first information of the sensing node for sending the sensing signal does not include the third information, the second information included in the first information of the sensing node for sending the sensing signal indicates that the sensing node for sending the sensing signal sends the information related to the sensing signal to the second network function. The second network function may be SF-U; the information related to the sensing signal includes but is not limited to one or more of the signal mode, amplitude, and phase of the sensing signal, and is not specifically limited.

[0189] If the perception node receiving the echo signal is responsible for processing the perception data, then the first information of the perception node for receiving the echo signal includes the third information; if the first information of the perception node for receiving the echo signal does not include the third information, the perception data is processed by the second network function. At this time, the second information included in the first information of the perception node for sending the perception signal indicates that the perception node for sending the perception signal sends information related to the perception signal to the second network function.

[0190] It should be understood that the first network function is configured to receive the perception data of the perception node for receiving the echo signal, and the perception data can be processed by the perception node for receiving the echo signal, or by the core network. In the case where the core network is responsible for processing the perception data, the perception node for sending the perception signal needs to send the information related to the perception signal to the core network, such as the second network function; in the case where the perception node for receiving the echo signal processes the perception data, the perception node for sending the perception signal needs to send the information related to the perception signal to the perception node for receiving the echo signal; in the case where there is no network interface such as an Xn interface directly connected between the perception node for sending the perception signal and the perception node for receiving the echo signal, the perception node for sending the perception signal needs to transmit the perception data to the perception node for receiving the echo signal through the core network. It is worth noting that the number of perception nodes for sending perception signals is not limited, and the number of perception nodes for receiving echo signals is not limited. The first network function can realize data fusion of multiple perception nodes and improve the accuracy of perception results.

[0191] In case that the sensing node receiving the echo signal is updated, the first information for the sensing node receiving the echo signal may include fourth information.

[0192] The first information of the sensing node for receiving the echo signal may include: information of the sensing node for sending the sensing signal. In practical applications, the information of the sensing node for sending the sensing signal may be sent to the sensing node for receiving the echo signal, so that the sensing node for receiving the echo signal can clearly identify the sensing signal sender, i.e., the cooperative sensing node. The information of the sensing node includes one or more of the identification, identity identification, and connection address of the sensing node.

[0193] The first information of the sensing node used to send the sensing signal may include: information of the sensing node used to receive the echo signal. In practical applications, the information of the sensing node used to receive the echo signal may be sent to the sensing node used to send the sensing signal, so that the sensing node used to send the sensing signal can clearly identify the echo signal receiver, that is, the cooperative sensing node.

[0194] In this embodiment, the content of the first information is clarified to configure the corresponding sensing node to perform the sensing task, so as to ensure that the sensing target can be continuously tracked when the sensing node is used to collaborate to complete the sensing task.

[0195] To configure the corresponding sensing node to perform the sensing task, in one embodiment, the first information further includes one or more of the following:

[0196] Perceive the type of business;

[0197] Perceive information related to the target;

[0198] Report parameter information;

[0199] Perceive QoS parameter information.

[0200] In actual applications, the network device is configured as a perception node, and the first information also includes the type of perception service and / or information related to the perception target; the terminal is configured as a perception node, and the first information also includes the type of perception service and / or information related to the perception target and / or reporting parameter information and / or perception QoS parameter information.

[0201] In this embodiment, by sensing the type of service and / or information related to the sensing target and / or reporting parameter information and / or sensing QoS parameter information, the sensing node can be instructed to better perform the sensing task, further ensuring that the sensing target can be continuously tracked when the sensing node is used to collaborate to complete the sensing task.

[0202] In one embodiment, the communication perception method further includes:

[0203] Sending fifth information to the network device; wherein,

[0204] The network device represents the network device to which the third perception node is connected; the fifth information includes the information of the third perception node and the perception QoS requirement information, which is used to assist the network device in allocating perception resources to the third perception node.

[0205] Here, when the perception node of the access network device participates in the performance of the perception task, for example, the first network function configures the terminal as the third perception node to perform the perception task, and the network device needs to provide the terminal with air interface related resource configuration so that the terminal can perform data transmission; at this time, the first network function sends the fifth information to the network device, and the fifth information includes the information of the third perception node, the perception method and the perception QoS requirement information to assist the network device in allocating perception resources to the terminal. It is worth noting that the first network function also configures one or more of the following for the terminal: perception task control parameters, data transmission channel, data processing mode, and the specific configuration content is not limited.

[0206] In this embodiment, the configuration information required for different sensing nodes to complete the sensing task is explicitly configured to ensure that the different sensing nodes can perform the sensing task.

[0207] In one embodiment, the communication perception method further includes:

[0208] Sending sixth information to the fourth sensing node; wherein,

[0209] The fourth sensing node represents a sensing node among the one or more sensing nodes that is unable to execute the sensing task, and the sixth information indicates stopping or canceling the execution of the sensing task.

[0210] Here, the first network function determines a perception node that cannot perform the perception task from one or more perception nodes that perform the perception task, obtains a fourth perception node, and sends sixth information to the fourth perception node.

[0211] In this embodiment, the subsequent operation of the perception node that cannot perform the perception task is given, and the sixth information is sent to the perception node that cannot perform the perception task to instruct to stop or cancel the execution of the perception task, which can avoid waste of resources.

[0212] When multiple perception requests are directed to the same perception target or perception area, the information in the perception requests may overlap. In order to achieve efficient execution of perception tasks and improve resource utilization, it is necessary to coordinate and manage perception requests and perception tasks. Based on this, the embodiment of the present application also provides a communication perception method, which is applied to a first network function. The first network function may include one or more of the following: SF-C, SF, data plane control function. Figure 5 As shown, the method includes:

[0213] Step 501: Receive multiple perception requests.

[0214] Here, multiple perception requests may be received from the AF and / or internal NF and / or UE.

[0215] Step 502: Determine a first perception task based on a first perception request among the multiple perception requests, where the first perception request represents a perception request with the same perception target and / or perception area.

[0216] Among them, the first perception request represents a perception request with completely or partially identical information among multiple perception requests.

[0217] Here, when it is determined that there are different perception requests with the same perception target and / or the same perception area in multiple perception requests, the first network function determines the different perception requests with the same perception target and / or the same perception area as the first perception request, and determines the first perception task based on the information carried by the first perception request, and the first perception task has the same perception target and / or the same perception area.

[0218] In one embodiment, the sensing QoS requirement and / or the sensing result reporting requirement of the first sensing request are the same; or,

[0219] One or more of the following information of the first perception request is different:

[0220] Reporting frequency;

[0221] Reporting time interval;

[0222] Perception data processing level;

[0223] Perception data processing level;

[0224] Perception results open level;

[0225] Perceive the results level.

[0226] Here, the first perception request may be a perception request with the same perception target and / or the same perception area, the same perception QoS requirement and / or the same perception result reporting requirement.

[0227] The first perception request may also be a perception request with the same perception target and / or the same perception area, but different reporting frequencies and / or different reporting time intervals and / or different perception data processing levels and / or different perception data processing levels and / or different perception result open levels and / or different perception result levels.

[0228] For example, the first perception request satisfies one or more of the following:

[0229] The sensing targets and / or sensing areas are the same, and the sensing QoS requirements and / or sensing result reporting requirements are the same;

[0230] The sensing target and / or sensing area are the same, but the reporting frequencies are different; different reporting frequencies include, for example, reporting once every 100 milliseconds (ms) and reporting once every 1 second (s);

[0231] The perception target and / or perception area are the same, but the perception data processing level and / or the perception result opening level are different; the perception data processing level includes, for example, the perception result that needs preliminary processing, the perception intermediate result and the perception result that has been deeply processed.

[0232] In this embodiment, a method for determining the first perception request among multiple perception requests is clearly defined so as to coordinate and manage the multiple perception requests, thereby enabling efficient execution of subsequent perception tasks and improving resource utilization.

[0233] The first network function may determine the first sensing task based on the sensing node capability, such as the sensing data reporting capability of the sensing node, the first sensing request, and the second network function processing data capability; the second network function may be SF-U. In one embodiment, the first sensing task is used to indicate one or more of the following:

[0234] Seventh information, the seventh information indicating that the perception result is reported with the maximum reporting frequency and / or the shortest time interval and / or the longest time requirement of the first perception request;

[0235] retaining the intermediate processing result of the first perception task;

[0236] Provides perception results at multiple levels of perception data processing.

[0237] Specifically, for first perception requests with the same perception target and / or the same perception area, the same perception QoS requirement and / or the same perception result reporting requirement, the first perception requests may be merged;

[0238] For the first perception request with different reporting frequencies, the first perception task can be configured to indicate the seventh information; it is worth noting that when the second network function is configured to process the perception data at the same time, the perception results of different time granularities need to be provided;

[0239] For the first perception request with different perception data processing levels, the first perception task can be configured to indicate retaining the intermediate processing result of the first perception task and provide perception results of multiple perception data processing levels.

[0240] It is worth noting that the perception result can be obtained by SF-U processing the perception data, or it can be obtained by the perception node used to receive the echo signal processing the perception data; the first perception task is used to indicate the seventh information and / or retain the intermediate processing result of the first perception task and / or provide the perception results of multiple perception data processing levels, which can be an indication of the way in which SF-U processes the perception data, or it can be an indication of the way in which the perception node used to receive the echo signal processes the perception data.

[0241] In this embodiment, the first perception task indication contents corresponding to different first perception requests are different, so as to ensure that the perception tasks corresponding to different perception requests can be met and help achieve efficient execution of the perception tasks.

[0242] Step 503: Send first information to one or more sensing nodes.

[0243] The one or more sensing nodes are used to perform the first sensing task.

[0244] In this embodiment, multiple perception requests can be processed jointly to achieve the purpose of improving perception accuracy, expanding perception range, and enhancing perception continuity, thereby meeting the needs of perception target capture and continuous tracking.

[0245] In one embodiment, the one or more sensing nodes are determined or updated by the first network function based at least on capability information of the network nodes and / or requirement information of the first sensing request.

[0246] In this embodiment, one or more perception nodes are determined or updated based on at least the capability information of the network nodes and / or the demand information of the first perception request, so as to utilize appropriate perception nodes to collaboratively perceive the perception targets, ensure the continuity of the perception services, and ensure the ability to continuously track the perception targets to improve the collaborative perception capabilities.

[0247] In one embodiment, the first information includes one or more of the following:

[0248] a sensing mode, wherein the sensing mode indicates a collaborative sensing mode or an independent sensing mode;

[0249] second information, where the second information instructs the sensing node used to send the sensing signal to send information related to the sensing signal to the second network function or the sensing node used to receive the echo signal;

[0250] third information, wherein the third information instructs the sensing node for receiving the echo signal to process the sensing data;

[0251] Fourth information, the fourth information instructing the first sensing node to send sensing data to the second sensing node, the first sensing node representing the sensing node for receiving the echo signal before the update, and the second sensing node representing the sensing node for receiving the echo signal after the update;

[0252] Information of the sensing node used to send the sensing signal;

[0253] Information of sensing nodes for receiving echo signals;

[0254] Perceive the type of business;

[0255] Perceive information related to the target;

[0256] Report parameter information;

[0257] Perceive QoS parameter information.

[0258] The first information can be found in the above embodiment and will not be described in detail here.

[0259] In this embodiment, the content of the first information is clarified to ensure that the sensing target can be continuously tracked when the sensing nodes are used to collaborate to complete the sensing task.

[0260] For the first sensing request that can be processed in combination, a mapping relationship between the sensing request and the sensing task, i.e., a first relationship, can be established, for example, mapping multiple sensing request identifiers (Sensing Request IDs) to one sensing task identifier (Sensing Task ID); the eighth information can also be determined. Based on this, in one embodiment, the communication sensing method further includes:

[0261] Establishing a first relationship; and / or

[0262] Sending the first relationship and / or the eighth information to the second network function; wherein,

[0263] The eighth information indicates the perception data processing information and / or the perception data open information, and the first relationship includes one or more of the following:

[0264] the correspondence between sensing requests and sensing tasks;

[0265] the correspondence between perceptual tasks and perceptual outcomes;

[0266] The correspondence between perception results and perception requests.

[0267] Here, a perception task may correspond to perception results of multiple levels, and the perception results of multiple levels may include, for example, perception results after preliminary processing, perception intermediate results, and perception results after deep processing. A perception result may also be open to different perception requests, and the first relationship may include one or more of the following: the correspondence between perception requests and perception tasks; the correspondence between perception tasks and perception results; the correspondence between perception results and perception requests. For example, the correspondence between perception requests and perception tasks may be established by mapping the Sensing Request ID to the Sensing Task ID, the correspondence between perception tasks and perception results may be established by mapping the Sensing Task ID to the perception result identifier (Sensing Result ID), and the correspondence between perception results and perception requests may be established by mapping the Sensing Result ID to the Sensing Request ID.

[0268] The eighth information indicates the perception data processing information and / or the perception data open information, and the eighth information is used to configure the second network function to process the perception data and the reporting mode of the perception result. For example, if a perception task is used to indicate the seventh information and / or retain the intermediate processing result of the first perception task and / or provide the perception results of multiple perception data processing levels, the second network function is required to perform corresponding processing on the perception data and / or perception results sent by the perception node, and the eighth information is used to instruct the second network function to perform corresponding processing.

[0269] Specifically, the eighth information indicates one or more of the following: processing the perception data at one or more time intervals; processing the perception data at one or more frequencies; retaining intermediate processing results of the perception data; providing and / or opening the perception results of multiple perception data processing levels; providing and / or opening the perception results of multiple perception data processing levels.

[0270] In this embodiment, in order to avoid confusion between perception requests, perception tasks and perception results, efficient execution of the perception task is achieved by establishing a first relationship and / or sending the eighth information.

[0271] In one embodiment, the communication perception method further includes:

[0272] Receiving a first perception result sent by a second network function;

[0273] Based on the first perception result and the correspondence between the perception result and the perception request, a second perception result is sent to the requester of the multiple perception requests.

[0274] Here, the first network function sends a second perception result to the requester of multiple perception requests based on the first perception result and the correspondence between the perception result and the perception request. The second perception result is determined by combining or splitting the first perception result based on the correspondence between the perception result and the perception request. The second perception result may be the same as or different from the first perception result.

[0275] It should be understood that when the second network function clearly defines the correspondence between the perception request and the perception result, the second network function can also directly send the second perception result to the requester of multiple perception requests based on the first perception result and the correspondence between the perception result and the perception request.

[0276] In this embodiment, based on the first perception result and the correspondence between the perception result and the perception request, the second perception result is sent to the requester of multiple perception requests, which can further avoid confusion between the perception request and the perception result.

[0277] Corresponding to the communication perception method on the first network function side, the embodiment of the present application further provides a communication perception method, which is applied to the second network function, and the second network function may be SF-U. Figure 6 As shown, the method includes:

[0278] Step 601: Receive perception data sent by one or more perception nodes, where the one or more perception nodes are determined or updated by a first network function based at least on capability information of the network node and / or requirement information of a perception request.

[0279] Here, the perception data sent by one or more perception nodes is received, and the perception data may be the perception data obtained based on the received echo signal, that is, the original perception data, or the perception data after the obtained perception data is processed. The first network function may be SF-C. It should be understood that the one or more perception nodes may transmit the original perception data and / or the processed perception data to the second network function through the data transmission tunnel.

[0280] In this embodiment, one or more perception nodes are determined or updated based at least on the capability information of the network nodes and / or the requirement information of the perception request, and perception data sent by one or more perception nodes are received, which can ensure that multiple perception nodes perform collaborative perception and help improve collaborative perception capabilities.

[0281] In one embodiment, the communication perception method further includes:

[0282] The perception data is processed based on the eighth information and / or the ninth information to obtain a perception result; the eighth information indicates perception data processing information and / or perception data open information, and the ninth information indicates information related to the perception signal.

[0283] Here, the eighth information may be sent by the first network function to the second network function. The eighth information may be determined based on the perception request received by the first network function, such as the first perception request, and is used to configure the manner in which the second network function processes the perception data and the reporting mode of the perception result. The ninth information may be sent by the perception node for sending the perception signal to the second network function. The ninth information includes, but is not limited to, one or more of the signal mode, amplitude, and phase of the perception signal, without specific limitation.

[0284] In this embodiment, the obtained perception results are relatively accurate, so as to help realize the efficient execution of the perception task.

[0285] In one embodiment, the communication perception method further includes:

[0286] receiving the eighth information sent by the first network function; and / or,

[0287] The ninth information sent by the fifth perception node is received, where the fifth perception node represents a perception node used to send a perception signal.

[0288] In this embodiment, the senders of the eighth information and the ninth information are clarified to help improve the accuracy of the perception result.

[0289] When the first network function coordinates and manages the perception request, the eighth information of the second network function needs to be configured. In one embodiment, the eighth information indicates one or more of the following:

[0290] processing the sensory data at one or more time intervals;

[0291] processing the sensory data at one or more frequencies;

[0292] retaining intermediate processing results of the perception data;

[0293] Providing and / or exposing the perception results of multiple perception data processing levels;

[0294] Providing and / or exposing perception results from multiple perception data processing levels.

[0295] For example, when the reporting frequency of the first perception request received by the first network function is different, the second network function needs to be configured to provide perception results of different time granularities when processing the perception data, that is, the eighth information indicates processing the perception data at one or more time intervals, or processing the perception data at one or more frequencies;

[0296] When the first perception request received by the first network function has different perception data processing levels and / or different perception result opening levels, the second network function needs to be configured to retain the intermediate processing results of the perception data when processing the perception data, and provide perception results of multiple perception data processing levels, that is, the eighth information indicates retaining the intermediate processing results of the perception data, and / or providing and / or opening the perception results of multiple perception data processing levels, and / or providing and / or opening the perception results of multiple perception data processing levels.

[0297] In this embodiment, clarifying the content indicated by the eighth information can improve the processing efficiency of the perception data.

[0298] To avoid confusion among the sensing request, the sensing task and the sensing result, in one embodiment, the communication sensing method further includes:

[0299] Receive a first relationship sent by the first network function; the first relationship includes one or more of the following:

[0300] the correspondence between sensing requests and sensing tasks;

[0301] the correspondence between perceptual tasks and perceptual outcomes;

[0302] The correspondence between perception results and perception requests.

[0303] It should be understood that the sensing task may be determined based on the sensing request.

[0304] In this embodiment, by receiving the first relationship, confusion among the perception request, the perception task and the perception result can be avoided.

[0305] In one embodiment, the communication perception method further includes:

[0306] Sending a first perception result to the first network function; and / or,

[0307] Based on the first perception result and the correspondence between the perception result and the perception request, a second perception result is sent to the requester of the perception request.

[0308] It is worth noting that the first perception result is obtained by the second network function processing the received perception data.

[0309] In this embodiment, based on the first perception result and the correspondence between the perception result and the perception request, the second perception result is sent to the requester of multiple perception requests, which can further avoid confusion between the perception request and the perception result.

[0310] The following takes the first network function as SF-C, the second network function as SF-U, and the third network function as AMF as an example, and further describes the present application in detail in combination with the application embodiments.

[0311] Configuring network devices to perform sensing tasks, such as Figure 7 As shown, the following steps are included:

[0312] Step 1: External AF, i.e., a third-party application, initiates a perception request through the network exposure function (NEF).

[0313] Specifically, NEF can request authorization for the perception service from the Unified Data Management (UDM) or Policy Control Function (PCF); after successful authorization, NEF forwards the perception request initiated by AF to AMF.

[0314] Step 2: The internal NF initiates a sensing request.

[0315] Step 3: UE initiates a sensing request. Figure 7 In the RAN, access is performed through base station A (RAN A) or base station B (RANB).

[0316] It is worth noting that steps 1 to 3 are in parallel and can be executed in whole or in part.

[0317] Step 4: AMF selects SF and / or SF-C according to the location information of the sensing target in the sensing request, the type of sensing service and the capabilities supported by SF. SF includes SF-C and SF-U.

[0318] Step 5: AMF sends a sensing request to SF-C.

[0319] Step 6: Based on the capability information of the network nodes, the requirement information of the sensing request and the network topology, the SF-C determines base station A (RAN A) and base station B (RAN B) in the network nodes as sensing nodes for collaborative sensing.

[0320] Step 7: SF-C sends corresponding first information to base station A and base station B respectively.

[0321] Specifically, the first information sent to the base station A includes: a sensing mode indicating a collaborative sensing mode (A sends and B receives), second information, information about a sensing node for receiving an echo signal, i.e., information about the base station B, a type of sensing service, and information related to a sensing target;

[0322] The first information sent to base station B includes: information indicating that base station B receives an echo signal, a sensing method indicating a collaborative sensing mode, third information, information about a sensing node used to send a sensing signal, i.e., information about base station A, the type of sensing service, and information related to a sensing target; and a data transmission tunnel is established between RAN B and SF-U.

[0323] Step 8: When RAN B needs to process the sensing data, RAN A sends information related to the sensing signal to RAN B.

[0324] Step 9: When SF-U processes the perception data, RAN A sends the information related to the perception signal to SF-U to facilitate SF-U to process the perception data. Since no data transmission tunnel is established between RAN A and SF-U, the information related to the perception signal is sent to SF-U through AMF and SF-C.

[0325] Step 10: RAN A and RAN B collaborate to perform the sensing task to sense the same sensing target.

[0326] Step 11: RAN B reports the sensing measurement results (also called sensing data) to SF-U, which may carry the information of the sensing target to facilitate SF-U to match the sensing data. The sensing data reported may be sensing data obtained based on the echo signal or processed sensing data.

[0327] Configuring the terminal to perform the sensing task flow diagram, such as Figure 8 As shown, the following steps are included:

[0328] Step 1: The requester initiates a sensing request.

[0329] Step 2: AMF selects SF and / or SF-C based on the location information of the sensing target in the sensing request, the type of sensing service and the capabilities supported by the SF.

[0330] Step 3: AMF sends a sensing request to SF-C.

[0331] Step 4: Based on the capability information of the network nodes, the requirement information of the sensing request and the network topology, SF-C determines terminal A (UE A) and terminal B (UE B) in the network nodes as sensing nodes for collaborative sensing.

[0332] It should be understood that SF-C may also determine UE A or UE B as a perception node in the network node to perform independent perception.

[0333] Step 5: The SF-C sends fifth information to the base station (RAN) to which the sensing node UE (UE A and UE B) accesses, instructing the RAN to allocate sensing resources to the UE.

[0334] Step 6: The SF-C sends the corresponding first information to the perception node UE; and establishes a data transmission tunnel between the UE reporting the perception data and the SF-U.

[0335] Specifically, the first information sent to UE A includes: a sensing mode indicating a collaborative sensing mode, second information, information of a sensing node for receiving an echo signal, i.e., information of UE B, a type of sensing service, information related to a sensing target, reporting parameter information, and sensing QoS parameter information;

[0336] The first information sent to UE B includes: information indicating that UE B receives an echo signal, a perception method indicating a collaborative perception mode, third information, information about a perception node used to send a perception signal, i.e., information about UE A, the type of perception service, information related to the perception target, reporting parameter information, and perception QoS parameter information.

[0337] Step 7: UE A and UE B collaborate to perform a sensing task such as performing sensing measurements.

[0338] Step 8: The corresponding sensing node UE reports the sensing measurement result (sensing data) to the SF-U.

[0339] Taking RAN A and RAN B cooperative sensing, sensing node base station A sends a sensing signal, and sensing node base station B receives an echo signal as an example, the schematic diagram of the sensing node sending the sensing signal is updated, as shown in FIG. Fig. 9 As shown, the following steps are included:

[0340] Step 1: As the sensing target moves, RAN B cannot receive the echo signal and reports it to SF-C. SF-C determines that RANA cannot continue sensing.

[0341] Step 2: SF-C determines that RAN A cannot continue to perform sensing because the sensing result reported by SF-U cannot meet the sensing QoS requirement and / or sensing accuracy requirement of the sensing request.

[0342] It is worth noting that steps 1 to 2 may be performed in whole or in part.

[0343] Step 3: Based on the capability information of the network nodes, the requirement information of the sensing request and the network topology, SF-C redefines the sensing nodes in the network nodes and updates RAN A to base station C (RAN C); RAN C and RAN B are determined as sensing nodes for collaborative sensing.

[0344] Step 4: SF-C updates the information of the cooperative sensing node to RAN B. RAN C serves as the sender of the new sensing signal, that is, the information of the sensing node used to send the sensing signal is updated to the information of RAN C.

[0345] Step 5: SF-C sends the corresponding first information to RAN C.

[0346] Specifically, the first information sent to RAN C includes: a sensing method indicating a collaborative sensing mode, second information, information about a sensing node for receiving an echo signal, namely, information about base station B, a sensing service type, and information related to a sensing target.

[0347] Step 6: The SF-C sends sixth information to the RAN A, instructing to cancel the sensing task.

[0348] Step 7: When RAN B needs to process the sensing data, RAN C sends information related to the sensing signal to RAN B.

[0349] Step 8: When SF-U processes the perception data, RAN C sends the information related to the perception signal to SF-U to facilitate SF-U to process the perception data. Since no data transmission tunnel is established between RAN C and SF-U, the information related to the perception signal is sent to SF-U through AMF and SF-C.

[0350] Update the schematic diagram of the sensing node receiving the echo signal, such as Fig.10 As shown, the following steps are included:

[0351] Step 1: As the sensing target moves, RAN B cannot receive the echo signal and reports it to SF-C. SF-C determines that RANB cannot continue sensing.

[0352] Step 2: SF-C determines that RAN B cannot continue to perform sensing because the sensing result reported by SF-U cannot meet the sensing QoS requirement and / or sensing accuracy requirement of the sensing request.

[0353] It is worth noting that steps 1 to 2 may be performed in whole or in part.

[0354] Step 3: Based on the capability information of the network nodes, the requirement information of the sensing request and the network topology, SF-C redefines the sensing nodes in the network nodes and updates RAN B to base station D (RAN D); RAN A and RAN D are determined as sensing nodes for collaborative sensing.

[0355] Step 4: SF-C updates the information of the cooperative sensing node to RAN A, and RAN D is used as the receiver of the new echo signal, that is, the information of the sensing node used to receive the echo signal is updated to the information of RAN D.

[0356] Step 5: SF-C sends the corresponding first information to RAN D; and establishes a data transmission tunnel between RAN D and SF-U.

[0357] Specifically, the first information sent to RAN D includes: information indicating that RAN D receives an echo signal, a perception method indicating a collaborative perception mode, third information, information about a perception node used to send a perception signal, namely, information about base station A, the type of perception service, and information related to the perception target.

[0358] Step 6: SF-C sends sixth information to RAN B, instructing to cancel the sensing task.

[0359] Step 7: SF-C indicates that the first information also includes fourth information. For example, RAN B provides the result generated by previously processing the sensing data to RAN D as auxiliary information.

[0360] Step 8: When RAN D needs to process the sensing data, RAN A sends information related to the sensing signal to RAN D.

[0361] Step 9: RAN D reports the sensing measurement result, i.e., the sensing data, to SF-U, which may carry the information of the sensing target, so that SF-U can match the sensing data. The sensing data reported may be sensing data obtained based on the echo signal or processed sensing data.

[0362] For the application scenario where different requesters initiate multiple perception requests, a schematic diagram of the coordination management process of multiple perception requests is shown in the figure. Fig.11 As shown, the following steps are included:

[0363] Step 1: AMF selects SF and / or SF-C based on the location information of the sensing targets in multiple sensing requests, the type of sensing services and the capabilities supported by the SF.

[0364] Step 2: AMF sends multiple sensing requests to SF-C.

[0365] Step 3: The SF-C determines the first perception request, sends corresponding first information to one or more perception nodes, and establishes a first relationship. The one or more perception nodes are determined or updated by the SF-C based on at least the capability information of the network node and / or the requirement information of the first perception request.

[0366] Step 4: SF-C sends the eighth information and the first relationship to SF-U.

[0367] Step 5: SF-C configures one or more sensing nodes to perform the first sensing task.

[0368] Step 6: One or more perception nodes, such as RAN, report the perception measurement results, i.e., perception data, to SF-U. The reported perception data may be perception data obtained based on the echo signal or processed perception data. SF-U generates a first perception result based on the eighth information.

[0369] Step 7: SF-U notifies SF-C of the first perception result, and SF-C sends the second perception result to the requester of multiple perception requests based on the first perception result and the correspondence between the perception result and the perception request.

[0370] Step 8: SF-U directly sends the second perception result to the requesting parties of the multiple perception requests based on the first perception result and the corresponding relationship between the perception result and the perception request. It is worth noting that either step 7 or step 8 can be performed.

[0371] The communication perception method provided in this application supports the integrated perception and communication function design. When the processing capacity of a single perception node is insufficient, it can collaborate with other network nodes to complete the perception task; collaborative perception of multiple network nodes can improve perception accuracy, expand perception range, and enhance perception continuity to meet the needs of perception target capture and continuous tracking; when the perception target moves and the collaborative perception node is unable to continue to complete the perception task, the collaborative perception node can be updated to ensure the continuity of perception business; for multiple perception requests, completely identical or partially identical perception requests can be merged to improve resource utilization.
