[0047] The following is an explanation of some concepts and / or terms involved in an information determination and sending method, apparatus, device, system and storage medium provided in an embodiment of the present application.

[0048] 1. Communication and perception integration / synaesthesia integration:

[0049] Wireless communications and radar sensing have been developing in parallel for decades, but with limited overlap. They have a lot in common in terms of signal processing algorithms, equipment, and to some extent, system architecture. In recent years, the two systems have attracted more and more attention from researchers in terms of coexistence, cooperation, and joint design.

[0050] In the early days, people conducted extensive research on the coexistence of communication systems and radar systems, focusing on developing effective interference management techniques to enable two separately deployed systems to operate smoothly without interfering with each other. Although radar and communication systems may be co-located or even physically integrated, they transmit two different signals in the time / frequency domain. They share the same resources through cooperation to minimize the interference between each other when working simultaneously. Corresponding measures include beamforming, cooperative spectrum sharing, primary and secondary spectrum sharing, dynamic coexistence, etc. However, effective interference elimination usually has strict requirements on the mobility of nodes and the information exchange between nodes, so the improvement of spectrum efficiency is actually limited. Since the interference in the coexistence system is caused by the transmission of two independent signals, it is natural to ask whether we can use one transmission signal for communication and radar sensing at the same time. Radar systems usually use specially designed waveforms, such as short pulses and chirps, which enable high-power radiation and simplified receiver processing. However, these waveforms are not necessary for radar detection. Passive radar or passive sensing using different radio signals as sensing signals is a good example.

[0051] Machine learning, especially deep learning technology, further promotes the potential of non-dedicated radio signals for radar sensing. With these technologies, traditional radar is moving towards more general wireless sensing. Wireless sensing here can broadly refer to retrieving information from received radio signals instead of communication data modulated into the signal at the transmitter. For wireless sensing related to the location of the sensing target, the dynamic parameters such as the reflection delay, arrival angle, departure angle, Doppler of the target signal can be estimated through common signal processing methods; for sensing the physical characteristics of the target, it can be achieved by measuring the inherent pattern signals of the device, object, and living things. The two sensing methods can be called perception parameter estimation and pattern recognition respectively. In this sense, wireless sensing refers to more general sensing technologies and applications using radio signals.

[0052] Integrated Sensing and Communication (ISAC) has the potential to integrate wireless sensing into large-scale mobile networks, where it becomes Perceptive Mobile Networks (PMNs). PMNs can evolve from the current 5G mobile network and are expected to become a ubiquitous wireless sensor network while providing stable and high-quality mobile communication services. It can be built on top of the existing mobile network infrastructure without major changes to the network structure and equipment. It will unleash the maximum capacity of mobile networks and avoid the high infrastructure costs of building new wide-area wireless sensor networks separately. With the expansion of coverage, the integrated communication and sensing capabilities are expected to enable many new applications. Perceptive mobile networks are able to provide both communication and wireless sensing services and have the potential to become a ubiquitous wireless sensing solution due to their large broadband coverage and strong infrastructure. Their jointly coordinated communication and sensing capabilities will improve the productivity of our society and help give rise to a large number of new applications that cannot be effectively implemented by existing sensor networks. Some early work on passive sensing using mobile signals has demonstrated its potential. For example, traffic monitoring, weather forecasting, and rainfall remote sensing based on GSM radio signals. Sensing mobile networks can be widely used for communication and sensing in transportation, communications, energy, precision agriculture and security, where existing solutions are either not feasible or inefficient. It can also provide complementary sensing capabilities to existing sensor networks, with unique day and night operation capabilities, and the ability to penetrate fog, foliage and even solid objects.

[0053] 2. Synaesthesia configuration:

[0054] Generally speaking, after a perception task is determined, such as sensing the movement of an object, sensing the surrounding temperature and humidity, sensing the location of an object, etc., the terminal and the base station need to perform some corresponding configuration operations to cooperate in completing this perception task.

[0055] Terminal-related perception operations involve: identifying PLMN networks that can perform perception, selecting appropriate perception modes (base station sends and UE receives, UE sends and base station receives, UE sends and UE B receives), discovering and selecting cooperative UEs, adopting efficient perception measurement data processing methods (UE calculates perception results, UE reports perception measurement data and the network calculates perception results), obtaining available perception wireless resources, and following security and privacy policies.

[0056] Base station-related perception operations also involve some actions: selecting a suitable perception mode, choosing a suitable perception waveform and frequency band, and obtaining available perception wireless resources.

[0057] For example: If you want the terminal to sense the moving speed of a vehicle, then the terminal can be configured with the following parameters: terminal Uu port perception; terminal self-transmission and self-reception; terminal uses 3GPP access, 2.6GHz frequency band, 0.115m wavelength waveform (select perception frequency and waveform); perception accuracy: meter level; perception bandwidth is 100M (that is, the section from 2.5GHz-2.6GHz is used for communication perception); the terminal needs to report the perception results through the user interface, etc.

[0058] Therefore, in order to complete the sensing task, the terminal and the base station need to perform some configurations to collaboratively complete the sensing operation.

[0059] The following, in combination with the accompanying drawings, describes in detail the information determination and sending method provided by the embodiments of the present application through some embodiments and their application scenarios.

[0060] Currently, there is no solution for how to determine the perception configuration and how to send it to the terminal or base station (once a perception task is determined, how is the perception configuration of the terminal, RAN or core network element determined and sent). Therefore, the current problem is: after a 5G core network element, such as the SF network element (taking the SF network element as an example), determines a perception task, how to configure the perception configuration for the terminal, base station or core network element to perform the perception task.

[0061] The embodiment of the present application provides a method for determining and sending information, and the SF network element can generate a perception configuration based on at least one of the perception capability information and the perception context information of the perception device to indicate the device parameters or device configuration required for the perception task that the perception device needs to perform, so that the SF network element can send the perception configuration to the perception device to enable the perception device to perform the perception configuration operation to perform the perception task that needs to be performed. In this solution, after determining a certain perception task, the SF network element determines the perception configuration based on at least one of the perception capability information and the perception context information of the perception device, and the SF network element sends the perception configuration to the perception device, so that the perception device can accurately complete the perception task according to the received required device parameters or device configuration, thereby improving the efficiency and accuracy of communication perception.

[0062] The present application provides a method for determining and sending information. Figure 2 FIG. 1 is a flow chart showing a method for determining and sending information provided by an embodiment of the present application. Figure 2 As shown, the information determination and sending method provided in the embodiment of the present application may include the following steps 201 to 204.

[0063] Step 201: A first communication device generates second information according to first information.

[0064] In an embodiment of the present application, the first information includes at least one of the sensing capability information of the first sensing device and the sensing context information of the first sensing device. The sensing capability information is used to indicate the sensing capability of the first sensing device, and the sensing context information is used to indicate information related to the first sensing task currently being performed by the first sensing device. The second information is used to indicate the device parameters or device configuration required for the first sensing device to perform the second sensing task.

[0065] In an embodiment of the present application, the above-mentioned first communication device includes a perception network element (for example, a SF network element) having a perception function (perception control function and / or perception computing function).

[0066] In one implementation, the sensing capability information is used to indicate the capability of the first sensing device.

[0067] In one implementation, the sensing capability of the first sensing device includes a capability possessed by the first sensing device, and the capability is related to the sensing task.

[0068] In one implementation, the first sensing device uses the second information to adjust various parameters or configurations of the first sensing device to perform the second sensing task.

[0069] It should be noted that the first perception task currently executed by the above-mentioned first perception device can be understood as the first perception task being executed by the first perception device, that is, when the first communication device determines that the first perception device needs to execute the second perception task, the perception task being executed by the first perception device at this time is the first perception task, then the first communication device can send second information to the first perception device so that the first perception device executes the second perception task.

[0070] The first perception task currently executed by the first perception device refers to the first perception task currently being executed by the first perception device, or the first perception task being executed by the first perception device at this moment.

[0071] It should be noted that for the first perception device, it may only be able to perform one perception task at a time or a place, and cannot perform multiple perception tasks at the same time. For example, a terminal performs the speed perception task at 9-10 am, and cannot perform the temperature perception task at the same time. Because there may be only one perception device, therefore, when the first communication device determines that the first perception device needs to perform the second perception task, the first communication device needs to understand whether the first perception device is still performing other perception tasks at the same time (that is, to check whether the first perception task exists). If the first perception device has a first perception task that is being executed, then the first perception device may no longer be able to perform the second perception task.

[0072] It should be noted that the reasons why the first perception device cannot perform multiple perception tasks at the same time may be as follows: on the one hand, due to power consumption limitations, performing perception tasks requires more power consumption. Therefore, if multiple perception tasks are scheduled to be performed at the same time, it may exceed the energy consumption limit of the perception device. Therefore, the second perception task issued may be rejected or cannot be executed; another aspect is that the first perception device may only be able to perform perception tasks at one frequency point at a time. For example, a terminal can only perform one perception task at the 700M frequency point at the same time, and cannot perform the second perception task at 700M, or the terminal cannot perform the second perception task at the new 2.6GHz frequency point. Therefore, it can be understood that due to the limitation of the terminal or base station frequency point, it is impossible to perform multiple perception tasks at multiple frequencies at the same time, or it is impossible to perform multiple perception tasks at one frequency point. Another aspect is that, limited by the function of the first perception device, the first perception device itself may not be able to perform multiple perception tasks in parallel, and the first perception device can only perform one perception task at a time.

[0073] Optionally, in an embodiment of the present application, the first perception device may be a device that performs a second perception task, or a device that participates in a perception operation or a perception task.

[0074] Among them, the above-mentioned first sensing device includes at least one of the following: a terminal, a core network element, and a base station.

[0075] Optionally, in an embodiment of the present application, the first communication device may determine whether the first perception device is capable of performing the second perception task based on at least one of the perception capability information and the perception context information of the first perception device. Exemplarily, before the above step 201, the information determination and sending method provided in the embodiment of the present application further includes at least one of the following steps 205 and 206.

[0076] Step 205: The first communication device matches the perception capability information of the first perception device with the perception capability information required for the second perception task, and determines that the first perception device can perform the second perception task when the perception capability information of the first perception device matches the perception capability information required for the second perception task.

[0077] It should be noted that the above matching can be understood as: the matching degree or similarity between the perception capability information of the first perception device and the perception capability information required by the second perception task is greater than a preset threshold.

[0078] It can be understood that when the perception capability information of the first perception device matches the perception capability information or perception requirements required by the second perception task, that is, the perception capability of the first perception device is considered to meet the perception capability required by the second perception task, then the first perception device is considered to be able to perform the second perception task.

[0079] In one embodiment, the perception capability information of the first perception device matches the perception capability information required for the second perception task, which can be understood as the perception capability of the first perception device can reach or exceed the perception capability required for the second perception task, or can be understood as the first perception device has the capability required to perform the second perception task, or can be understood as some perception configurations required for the second perception task, such as perception mode, perception frequency or perception bandwidth, can be met on the first perception device, then the first perception device is deemed to be able to perform the second perception task.

[0080] For example, the second perception task requires the terminal to transmit and receive automatically, and perform speed perception operations with a bandwidth of 100M at the 2.6GHz frequency under 5G access. Therefore, from the above description, in order to perform the second perception task, the first perception device must have the following capabilities: at least support the perception mode of self-transmission and self-reception, at least support perception under 5G, at least support perception operations under 2.6GHz, at least support bandwidths above 100M, and support 100M bandwidth at the 2.6GHz frequency. If a terminal has a perception capability that exceeds the above minimum standards, it can be considered to be able to perform the second perception task. For example, if the terminal supports self-transmission and self-reception, and also supports self-transmission and self-reception by others, then it can be considered that in terms of perception mode, the first perception device exceeds the minimum requirements required for the perception task (must support self-transmission and self-reception). In this case, the first perception device can be identified by SF as meeting the requirements of the second perception task in terms of perception mode. The requirements for the remaining perception tasks can be derived in the same way. In one embodiment, the sensing capability information of the first sensing device matches the sensing capability information required for the second sensing task, which may mean that one or more of the communication sensing functions supported by the first sensing device matches the sensing capability information required for the second sensing task. In another embodiment, the sensing capability information of the first sensing device matches the sensing capability information required for the second sensing task, which may also be considered that the various sensing capabilities of the first sensing device match the sensing capability information or sensing requirements required for the second sensing task one by one, or even exceed the sensing capability information or sensing requirements required for the second sensing task. One by one matching means that the sensing mode of the first sensing device satisfies the sensing mode indicated in the sensing capability information required for the second sensing task, and the access mode supported by the first sensing device satisfies the sensing access mode indicated in the sensing capability information required for the second sensing task. Exceeding the sensing capability information or sensing requirements required for the second sensing task means, for example, that the second sensing task needs to support a sensing signal with a bandwidth of 100M under 5G, while the base station supports a sensing signal with a bandwidth of 200M under 5G. This may be considered that the base station far exceeds the sensing signal bandwidth requirement required by the sensing task, and therefore, is considered to exceed the sensing capability information or sensing requirements required for the second sensing task. For example, if the second perception task requires a single-transmit and single-receive perception mode and needs to use a 2.6 GHz frequency point for perception under 5G access, then if there is a first perception device, such as a terminal, then if the terminal can perform the second perception task, then the terminal can be:

[0081] The terminal meets at least one requirement of the second perception task, for example, the terminal meets at least one of single transmission and single reception, supports 5G access, and performs perception at a frequency of 2.6 GHz, and is considered to match the second perception task or meet the requirement of the second perception task;

[0082] It may also be that the terminal meets the requirements of all the second perception tasks, that is, the terminal simultaneously meets the requirements of single transmission and single reception, supports 5G access, and meets the requirements of perception at the 2.6 GHz frequency.

[0083] Step 206: The first communication device determines whether the first perception device can perform the second perception task according to the perception context information of the first perception device.

[0084] It can be understood that the first communication device determines the first perception task currently performed by the first perception device based on the perception context information of the first perception device, thereby determining whether the first perception device can perform the second perception task.

[0085] It can be understood that the perception context of the first perception device indicates the perception task currently being performed by the first perception device and the perception configuration required to perform the perception task. For example, the first perception device is currently performing perception task 1, which is a self-transmitting and self-receiving location perception at 3.5GHz under 5G access and using 100M bandwidth. For some sensing devices, there may be the following restrictions: (1) Some sensing devices may have a limit on the number of sensing tasks that can be executed at the same time and place. For example, the terminal can only execute one sensing task at the same time. If the current sensing device already has a sensing task being executed, the SF network element cannot assign a new sensing task to the device. (2) Some sensing devices may only be able to execute limited sensing tasks at the same frequency at the same time and place. For example, they can only execute one sensing task at 3.5GHz of 5G access. In this way, the SF network element cannot arrange this sensing device to execute other sensing tasks at 3.5GHz. However, the SF network element can arrange it at other frequencies, such as 2.6GHz of 5G, to execute new sensing tasks. In other words, the number of sensing tasks that can be executed may be limited by certain bandwidths at a certain frequency, but changing to a new frequency may be supported. (3) Some sensing devices may only be able to execute one scene of sensing at the same time and place. For example, they only support sensing speed and cannot support sensing temperature at the same time. Therefore, the purpose of introducing the perception context here is to indicate the perception task currently being performed by the perception device and the perception capability information or perception configuration required for the perception task. Then, SF can determine whether a new perception task can be assigned to the perception device based on the perception capability or configuration currently being used by the perception device.

[0086] It can be understood that the first communication device (such as the SF network element) determines whether the capability of the first perception device meets the requirements of the second perception task based on the capability of the first perception device and the perception capability information or perception requirements required by the second perception task; the first communication device can also determine the perception task currently being performed by the first perception device based on the perception context of the first perception device, and determine whether the first perception device can still perform the second perception task, because it is possible that the first perception task is to be performed on the first perception device at the same time as the second perception task. In one embodiment, the first communication device can make two judgments, first determine whether the capability meets the requirements of the second perception task, and then determine whether it can perform multiple perception tasks at the same time and in the same place (for example, whether the same frequency point can perform multiple tasks, or whether it can perform temperature or speed perception at the same time, or whether the same frequency point supports the transmission of perception signals on the same bandwidth, because the same frequency and bandwidth may have interference, whether the execution of multiple tasks will interfere with each other, which will affect the perception results, or whether the terminal can send and receive at the same time or only send but not receive, etc.), and finally determine whether the first perception device can perform the second perception task.

[0087] It should be noted that the above-mentioned perception capabilities are some inherent attributes or capabilities of perception devices (such as terminals or base stations), which will not change. That is, it refers to some capabilities supported by the perception device, which characterize whether the perception device can support certain perception operations or perception methods. The first communication device will judge whether the perception device can participate in a certain perception task based on the inherent capabilities of the perception device. For example, if a terminal does not have a sensor installed, it does not have the function of sensing temperature and humidity, so the first communication device cannot distribute a temperature perception task to this terminal. Alternatively, if a terminal or base station does not support perception at the intermediate frequency, for example, it does not support perception at 2.6Ghz or 3.5GHz, then a task that needs to be perceived at 2.6Ghz or 3.5GHz cannot be sent to such a terminal or base station.

[0088] Optionally, in an embodiment of the present application, the above-mentioned perception capability includes at least one of the following: a communication perception function supported by the first perception device, an object that the first perception device can perceive, and a perception scene supported by the first perception device.

[0089] Optionally, in an embodiment of the present application, the communication perception function supported by the above-mentioned first perception device includes at least one of the following: an identifier of the first perception device, a perception mode supported by the first perception device, an access method supported by the first perception device, a perception frequency supported by the first perception device, a perception waveform parameter supported by the first perception device, a perception resolution supported by the first perception device, a perception accuracy supported by the first perception device, the duration of a task perceived by the first perception device (hereinafter referred to as the perception task duration), the maximum number of perception tasks supported by the first perception device to be executed simultaneously (hereinafter referred to as the maximum number of concurrent perception tasks), the type of perception service supported by the first perception device, and the area information on which the first perception device can perform perception tasks (hereinafter referred to as the perception area information).

[0090] Here we explain or define the various functions included in the above communication perception function:

[0091] The identifier of the first sensing device, such as terminal ID, base station ID, operating system ID, etc. It can also be an identifier for some APP to sense, such as the ID of the sensing application, etc.

[0092] The sensing modes supported by the first sensing device include: the first sensing device supports self-transmission and self-reception, the first sensing device does not support self-transmission and self-reception, the first sensing device supports only transmission but not reception, or the first sensing device does not support only transmission but not reception, or the first sensing device supports only reception but not transmission, etc. The so-called self-transmission and self-reception here means that the first sensing device autonomously transmits a sensing waveform through the radio frequency unit, and after the sensing waveform is reflected by the obstacle, the first sensing device also receives the reflected echo through the signal receiving module. Therefore, for the device whose sensing mode supports self-transmission and self-reception, it has certain requirements for the radio frequency module and the receiving module of the device. Therefore, when the second sensing task has requirements for the sensing mode, it is necessary to match and compare the sensing mode supported by the first sensing device with the sensing mode required by the second sensing task. If the second sensing task requires the self-transmission and self-reception mode, and the first sensing device does not support the self-transmission and self-reception, it is considered that the first sensing device cannot perform the second sensing task because the sensing mode supported by the first sensing device cannot meet the requirements of the second sensing task. Similarly, several sensing modes such as only transmission but not reception and only reception but not transmission can be explained.

[0093] The access mode supported by the first perception device may refer to: the wireless access mode or PDU session access mode supported by the first perception device, and / or, the first perception device supports the performance of perception operations under these wireless access modes or PDU session access modes. The wireless access mode, RAT type, includes: 3GPP access, non-3GPP access, etc., wherein 3GPP access includes 5G access, 4G access, etc., and non-3GPP access includes WLAN access, wifi access, Bluetooth access, etc. An example of the first perception device supporting the performance of perception operations under these wireless access modes or PDU session access modes is that the first perception device supports the performance of perception operations (for example, perception of speed or temperature) under 5G access. It can be understood that some perception tasks need to be performed under specific access modes.

[0094] The selection of the perception frequency supported by the first perception device refers to the frequency points at which the first perception device supports the execution of perception operations or perception tasks. For example, the first perception device supports access to 700M, 900M, 2.6GHz, and 3.5GHz frequencies under 5G access, but the first perception device only supports the execution of perception operations or perception tasks under 700M. This means that the perception device only supports 700M, and although 5G access can be performed under other frequencies, perception tasks or perception operations cannot be performed.

[0095] The first perception waveform parameter supported by the perception device means that the perception device needs to send a perception waveform (pulse waveform or orthogonal frequency division multiplexing (OFDM) waveform, or orthogonal time and frequency space (OTFS) waveform, etc.) at a specific frequency point and a specific bandwidth, and then hit the surface of the perceived object and reflect back, and then be received by other devices. The perception waveform parameter refers to the frequency and period at which these waveforms are sent, as well as the shape of the waveform, whether it is a pulse waveform, an amplitude waveform, or an orthogonal waveform, etc. The selection of this transmitted waveform is very particular, including the use of pulse waveforms, OFDM waveforms, or OTFS waveforms, etc. The choice of waveforms also strictly affects the results of the perception task. For example, OFDM perception is not friendly, because we perceive the perception results such as distance, position, speed, etc., which cannot be directly reflected in the OFDM signal; OTFS signals have great advantages. In essence, they are another projection of the time dimension signal, Fourier transform of the delay, and two-dimensional projection of Doppler frequency shift and delay. The perception results we care about, such as distance and speed, are directly orthogonal on the OTFS signal. Each grid corresponds to a distance and speed. However, it is difficult for OTFS to distinguish each frequency band in channel measurement. Therefore, the first communication device may strictly select the perception waveform parameters according to the requirements of the first perception task or the requirements of the perception scene. The parameters of the perception waveform may also include whether it is a continuous waveform or a pulse waveform, the period of the waveform, the frequency, the waveform bandwidth, the waveform duration, the power of the waveform, etc., all of which are required and standardized. In addition, the perception waveform is generally not friendly enough at low frequencies. The wavelength of the perception waveform is longer at low frequencies, resulting in a small digital aperture, which affects the perception effect. However, the low-frequency band network is widely deployed, so the application value is relatively high. Therefore, the first communication device needs to consider many factors when determining the perception waveform of the perception device.

[0096] The perception resolution of the first perception device refers to the perception accuracy. For example, if a higher perception resolution or perception accuracy is required, then the perception device needs to transmit the perception waveform at a higher power at the perception frequency or perception bandwidth to improve the accuracy of the perception result. Therefore, the proposal of perception resolution requires the first perception device to have higher radio frequency requirements, etc. For example, if the perception resolution is at the meter level or the centimeter level, then the requirements for the perception device at each level are also different. Generally, the higher the perception accuracy, the higher the requirements for the perception device, the more frequent the transmission beam, the greater the power of the transmission beam, etc. The perception resolution is similar to the resolution of the sensor. For example, the resolution of the above-mentioned temperature sensor is 0.1°C, and the full scale is 500°C, then its resolution is 0.1 / 500=0.02%.

[0097] The perception accuracy supported by the first perception device is similar to the perception resolution, which is also the accuracy of the perception results of the first perception device when performing different perception tasks or perceiving in different perception scenarios. For example, the temperature can be accurate to several decimal places, and whether the perception distance can be perceived at the meter level or decimeter level. The perception accuracy refers to the accuracy of the perception result of the perception device in a perception process, for example, compared with the actual position perception result, the error is about 2 meters, etc.

[0098] The perception task duration supported by the first perception device refers to the maximum duration of a perception task or a perception operation performed by the first perception device. For example, if the maximum supported perception task duration is one hour, then a perception task exceeding one hour (for example, continuously sensing the local temperature for 24 hours) cannot be scheduled for execution by this perception device.

[0099] The maximum concurrent number of sensing tasks supported by the first sensing device is also an inherent capability of a device, that is, a sensing device can execute several parallel sensing tasks at the same time and place. For example, if the maximum concurrent number of sensing tasks is 2, it means that this sensing task can only execute 2 sensing tasks at the same time and place, such as sensing temperature and speed, and no new sensing location tasks can be added. The maximum concurrent number of sensing tasks actually shows how many sensing tasks a sensing device can execute at the same time. When the number of sensing tasks currently being executed (for example, 2) is given in the sensing context of the first sensing device, and the sensing capability of the sensing device only supports two sensing tasks at most, it can be seen that no new sensing tasks can be arranged for the sensing device. Therefore, the first communication device SF can compare the number of sensing tasks being executed indicated in the sensing context with the maximum concurrent number of sensing tasks of the sensing device. If the number of sensing tasks executed by the sensing device has reached the upper limit of the maximum concurrent number of sensing tasks, then no new sensing tasks can be arranged. However, if a perception task ends after a certain time point in the future, then the number of perception tasks being executed by the perception device will be less than the maximum number of concurrent perception tasks. In this case, the first communication device can arrange a new perception task after this time point, or it can pre-arrange a perception task for the first perception device in advance. At this time, the first communication device will send the second information (for example, the perception configuration for executing the new perception task) and the time when the second information takes effect to the first perception device. In this way, the first perception device will immediately use the perception configuration indicated in the second information after reaching the time point, and adjust the configuration of the first perception device itself to execute the second perception task.

[0100] The type of perception service or the type of perception task supported by the first perception device is used to indicate the type of perception service supported by the first perception device, such as whether it supports speed perception, position perception, temperature perception, light perception, density perception, etc. Because the support for different types of perception tasks maps out the perception capabilities of the first perception device. For example, the perception of temperature requires the installation of relevant sensors; the perception of humidity also requires sensors with corresponding functions. Currently, most terminals do not have the function of temperature or humidity perception. Therefore, the type of perception service or the type of perception task can actually be used to screen out a suitable first perception device to perform this task. If the device cannot support this type of perception service, it will naturally not be selected by the first communication device to perform the perception operation.

[0101] The perception area information indicates what the first perception device supports and what perception is performed at what location. The location is easy to understand. For example, perception tasks can be performed under a specific cell ID (cell ID), tracking area (racking area, TA), data network name (Data Network Name, DNN), and data network access identifier (Data Network Access Identifier, DNAI). This actually regulates that the perception device can only perform some perception tasks in a specific area, rather than being able to perform perception operations at will in all locations. Therefore, the first communication device (SF network element) may send a subscription request to the AMF network element to request the location information of certain first perception devices, such as terminals or base stations; then, the first communication device determines whether the current first perception device can perform perception operations or be assigned perception tasks at this location based on the location information of the first perception device and the first perception device in the perception area information. If the perception area information indicates that the perception operation cannot be performed at the current location, the first communication device will not assign a perception task to the device. In addition, the sensing area information can also indicate that a specific sensing operation is performed in a specific location, for example, only location sensing is performed in the area of ​​cell ID = 001, or only sensing is performed in the 700M frequency band of 5G access. In this way, it is specified that the first sensing device performs the sensing operation with a specific sensing configuration under specific location information.

[0102] It is understandable that after the first sensing device receives the second information, the first sensing device may also perform the following operations:

[0103] If the first perception device is a terminal, the first perception device can send the second information to the application layer and to a specific application; the application uses the second information to adjust various parameters or configurations of the first perception device or the perception application to perform the second perception task.

[0104] If the first sensing device is a terminal, the first sensing device can send the second information to the operating system of the first sensing device; the operating system uses the second information to adjust various parameters or configurations of the first sensing device to perform the second sensing task. Here, adjusting various parameters or configurations of the first sensing device can also be adjusting various parameters or configurations of various modules on the terminal, such as the camera on the terminal, the power amplifier on the terminal, the screen, etc.

[0105] It can be understood that after the first perception device receives the second information, the first perception device can send the second information to the application, the operating system, the modem chip, and other modules on the first perception device (for example, a mobile phone camera, a camera, etc.). Then, the application, the operating system, the modem, other modules, etc. adjust the perception configuration or perform perception operations according to the requirements of the second information.

[0106] It can be understood that when the first perception device is a terminal, the terminal forwards the second information to the APP, the OS, the modem, and other modules on the terminal. This is a new terminal capability, that is, forwarding the perception configuration to the application on the terminal, or the OS, or the modem, or other modules on the terminal (for example, mobile phone camera, camera, amplifier, screen, etc.).

[0107] Optionally, in one embodiment of the present application, the sensing capability information of the first sensing device is sent by the first sensing device. Figure 2 ,like Figure 3 As shown, before the above step 201, the information determination and sending method provided in the embodiment of the present application also includes the following steps 207 and 208.

[0108] Step 207: The first perception device directly sends the perception capability information of the first perception device to the first communication device.

[0109] Step 208: The first communication device receives the sensing capability information of the first sensing device sent by the first sensing device.

[0110] Optionally, in another embodiment of the present application, the sensing capability information of the first sensing device is sent by the second communication device. Figure 2 ,like Figure 4 As shown, before the above step 201, the information determination and sending method provided in the embodiment of the present application also includes the following steps 209 and 210.

[0111] Step 209: The first perception device sends the perception capability information of the first perception device to the first communication device via the second communication device.

[0112] In an embodiment of the present application, the above-mentioned second communication device may be an AMF network element.

[0113] Step 210: The first communication device receives the sensing capability information of the first sensing device sent by the second communication device.

[0114] It can be understood that if the first perception device is a terminal, the perception capability information of the first perception device can be sent to the first communication device through an application layer message, a NAS message, a control plane message, etc. It can also be understood that if the first perception device is a terminal, the perception capability information of the first perception device can be first sent to the AMF network element through a NAS message, a control plane message, etc., and then the AMF network element sends the perception capability information of the first perception device to the first communication device.

[0115] It is understandable that if the first sensing device is a base station, the sensing capability information of the first sensing device can be sent to the first communication device through an N2 message, or through a control plane message, etc. It is also understandable that if the first sensing device is a base station, the sensing capability information of the first sensing device can be first sent to the AMF network element through a NAS message, or through a control plane message, or through an N2 message, etc., and then the AMF network element sends the sensing capability information of the first sensing device to the first communication device.

[0116] It should be noted that the above-mentioned perception context information refers to: a context of a perception task, that is, the details of the perception task in which the first perception device participates after the first perception device participates in the perception task. This perception context information is for the first communication device to determine the perception device (such as a terminal or base station) participating in the perception task. Because if a terminal has already participated in the temperature perception operation, it is unlikely to sense humidity or perception speed at the same time. Perception context information is also a key factor for the first communication device to determine the candidate perception device and determine the perception configuration.

[0117] Optionally, in an embodiment of the present application, the above-mentioned perception context information (i.e., information related to the first perception task currently performed by the first perception device) includes device parameters or device configuration required for the first perception device to perform the first perception task.

[0118] For example, if a terminal participates in speed perception at a frequency of 2.6 GHz, then if the first communication device still wants the terminal to participate in position perception, it still has to use the frequency of 2.6 GHz.

[0119] Optionally, in an embodiment of the present application, the device parameters or device configurations required for the first perception device to perform the first perception task include at least one of the following: a perception context identifier, an identifier of the first perception task, and various perception configurations of the first perception device when performing the first perception task.

[0120] Among them, the above-mentioned perception configurations include at least one of the following: perception mode, access method, perception frequency, perception waveform parameters, perception resolution, perception accuracy, perception task duration, perception service type, and perception area information.

[0121] Optionally, in an embodiment of the present application, after the first communication device, such as the SF network element, determines a certain perception task, it is necessary to establish perception context information, and the establishment method is:

[0122] (1) The SF network element establishes perception context information for the terminal or base station participating in the perception task, that is, it indicates the details of the perception task in which the terminal or base station participates.

[0123] For example, the sensing tasks that terminal 1 participates in are: task 1, task 2; the SF network element is terminal 1 participating in these two sensing tasks, and the established sensing context information is:

[0124] Task 1: Terminal 1: 5G, pulse waveform, single-transmit multiple-receive, 900M frequency band, time period: 9AM-10AM;

[0125] Task 2: Terminal 1: 5G, pulse waveform, single-transmit multiple-receive, 2.6GHz frequency band.

[0126] (2) The SF network element establishes the perception context information of this perception task.

[0127] For example, the sensing task is Task 1, and the sensing devices participating in the sensing task include Terminal 1, Terminal 2, Base Station 1, and Base Station 2. The sensing context information established by the SF network element for the sensing task is:

[0128] Terminal 1: 5G, pulse waveform, single-transmit multiple-receive, 900M frequency band, time period: 9AM-10AM;

[0129] Terminal 2: non-3GPP Access, single-transmit and single-receive, OTFS waveform, 2.6G frequency band, time period: 10AM-11AM.

[0130] It is understandable that SF will save each perception configuration corresponding to the perception task being performed by each perception device, and SF will also save the perception configuration information of each perception device required for each perception task. It is understandable that the perception context, on the one hand, is to save some detailed information of the perception task being performed by each perception device, which is used by SF to determine candidate perception devices for new perception tasks; in addition, the perception context can also save the details of each perception task, which perception devices are required for the perception task, what settings are made for each device, etc.

[0131] In one implementation, the terminal or RAN may trigger the SF to establish a perception context; or the SMF or AMF, or any core network element, may trigger the SF to establish a perception context of the perception terminal or the perception RAN.

[0132] Optionally, in an embodiment of the present application, the above-mentioned second information, i.e., the device parameters or device configuration required for the first sensing device to perform the second sensing task, includes at least one of the following: sensing mode, access method, sensing frequency selection information, sensing waveform parameters, sensing resolution, sensing accuracy, sensing task duration, sensing service type, information of the sensed target, information of a specific sensing node, and sensing area information.

[0133] Optionally, in an embodiment of the present application, for the terminal, the above-mentioned perception mode may include at least one of the following: a terminal self-transmitting and self-receiving mode, a terminal only sending and not receiving mode, and a terminal only receiving and not sending mode.

[0134] Optionally, in an embodiment of the present application, for the base station, the above-mentioned perception mode may include at least one of the following: a base station self-transmitting and self-receiving mode, a base station only sending and not receiving mode, and a base station only receiving and not sending mode.

[0135] It should be noted that the spontaneous transmission and reception here means that the terminal (or base station) sends a waveform of a frequency, which hits an object and is reflected by the object to produce an echo, and then the terminal (or base station) needs to receive the waveform returned by the object.

[0136] Optionally, in an embodiment of the present application, the above-mentioned access method refers to the access method when the perception device performs a perception task, and the above-mentioned access method (RAT type) includes at least one of the following: using Non-3GPP access method, using 3GPP access method, using Bluetooth access method, and using WiFi access method.

[0137] Optionally, in an embodiment of the present application, the above-mentioned 3GPP access method may include at least one of the following: cellular access method, LTE method, and 5G access method.

[0138] Optionally, in an embodiment of the present application, the above-mentioned Non-3GPP access method may include at least one of the following: WLAN access method, WiFi access method, and Bluetooth access method.

[0139] Optionally, in an embodiment of the present application, the above-mentioned perception frequency selection information may represent: after determining a certain access mode, a waveform or echo detection may be specified to be sent at a specific frequency. For example, when using 3GPP to access a 5G system, 2.6 GHz is used.

[0140] Optionally, in an embodiment of the present application, the device parameters or device configuration required for the first perception device to perform the second perception task include perception frequency selection information, and the perception frequency selection information is used to indicate the selection of performing the perception task or perception operation at the first frequency.

[0141] Among them, when the first frequency point is different from the communication frequency point of the first sensing device, the first sensing device needs to switch the communication frequency point to the first frequency point.

[0142] It can be understood that the sensing frequency here is different from the communication frequency of the first sensing device, and the sensing frequency may be a new frequency. For example, the terminal communicates at 700M, but the sensing frequency may be 2.5GHz. At this time, the sensing frequency is different from the communication frequency, and the terminal or base station needs to switch the frequency.

[0143] In one implementation, the SF network element sends the perception frequency required for the second perception task to the AMF network element, and the AMF network element sends the perception frequency to the base station via an N2 message; the AMF network element sends the perception frequency to the terminal via a NAS message. Then, the base station or the terminal can switch to the frequency indicated by the perception frequency to perform subsequent perception operations. The perception frequency includes at least one of the following: RFSP index (radio frequency selection policy), frequency information, etc.

[0144] Optionally, in the embodiment of the present application, the above-mentioned sensing waveform parameter may include at least one of the following: wavelength, frequency band, frame rate, transmission interval, etc. of the waveform emitted by the terminal or base station. It should be noted that the most important parameter here is the frequency band, such as emitting at a frequency of 4-5 GHz.

[0145] Optionally, in an embodiment of the present application, the above-mentioned perception resolution may include at least one of the following: distance resolution, angle resolution, and speed resolution. Among them, the distance resolution is related to the bandwidth of the perception signal, the angle resolution is related to the antenna aperture, and the speed resolution is related to the time domain width of the perception signal. When a certain perception resolution is reached, the first perception device adjusts parameters related to the perception resolution, such as the bandwidth of the perception signal or the antenna angle.

[0146] Optionally, in the embodiment of the present application, the above-mentioned perception accuracy may include at least one of the following: distance accuracy, speed accuracy, and angle accuracy. For example, the perception accuracy corresponding to the road vehicle monitoring scene includes distance accuracy, speed accuracy, and angle accuracy, the perception resolution includes distance resolution, speed resolution, and angle resolution, and the perception range includes distance range, speed range, and angle range.

[0147] It should be noted that the frequency of the emitted waveform and the perception resolution are used in combination. The higher the accuracy, the greater the power consumption.

[0159] The first sensing device selects a sensing waveform to be transmitted, and the configuration of the sensing waveform is the configuration of the sensing waveform indicated by the second information.

[0160] Step 202: The first communication device sends second information to the first sensing device.

[0161] In an embodiment of the present application, the second information is used by the first sensing device to perform a sensing configuration operation to perform a second sensing task.

[0162] Step 203: The first sensing device receives second information sent by the first communication device.

[0163] In an embodiment of the present application, the above-mentioned second information is used to indicate the device parameters or device configuration required for the first perception device to perform the second perception task; the second information is generated by the first communication device based on the first information, and the first information includes at least one of the perception capability information of the first perception device and the perception context information of the first perception device, the perception capability information is used to indicate the perception capability of the first perception device, and the perception context information is used to indicate information related to the first perception task currently being performed by the first perception device.

[0164] Optionally, in one implementation of the embodiment of the present application, in combination Figure 2 ,like Figure 5 As shown, the above step 202 can be specifically implemented by the following step 202a, and the above step 203 can be specifically implemented by the following step 203a.

[0165] Step 202a: The first communication device directly sends second information to the first sensing device.

[0166] Step 203a: The first sensing device receives second information directly sent by the first communication device.

[0167] In one implementation, the above-mentioned first perception device is a base station. After the first communication device generates second information for the base station (i.e., the device parameters or device configuration required for the base station to perform the second perception task), the first communication device directly sends the second information to the base station; after the base station receives the second information, it uses the second information to adjust the base station, such as adjusting the perception mode of the base station, adjusting the perception frequency band and frequency point of the base station, etc.

[0168] In another implementation, the above-mentioned first perception device is a terminal. After the first communication device generates second information for the terminal (i.e., the device parameters or device configuration required for the terminal to perform the second perception task), the first communication device directly sends the second information to the terminal; after the terminal receives the second information, it uses the second information to adjust the terminal, such as adjusting the terminal's perception mode, adjusting the terminal's perception frequency and perception bandwidth, etc.

[0169] Optionally, in another implementation of the embodiment of the present application, in combination with Figure 2 ,like Figure 6 As shown, the above step 202 can be specifically implemented by the following step 202b, and the above step 203 can be specifically implemented by the following step 203b.

[0170] Step 202b: The first communication device sends second information to the first sensing device via the second communication device.

[0171] Step 203b: The first sensing device receives second information sent by the first communication device via the second communication device.

[0172] In one implementation, the above-mentioned first perception device is a base station. After the first communication device generates second information for the base station (i.e., the device parameters or device configuration required for the base station to perform the second perception task), the first communication device first sends the second information to the second communication device, and then the second communication device sends the second information to the base station. For example, the second communication device can send the second information to the base station via an N2 message.

[0173] In another implementation, the above-mentioned first perception device is a terminal. After the first communication device generates second information for the terminal (i.e., the device parameters or device configuration required for the terminal to perform the second perception task), the first communication device first sends the second information to the second communication device, and then the second communication device sends the second information to the terminal. For example, the second communication device can send the second information to the terminal via a NAS message.

[0174] Optionally, in the embodiment of the present application, combined with Figure 6 ,like Figure 7 As shown, the above step 202b can be specifically implemented through the following steps 202b1 to 202b5, and the above step 203b can be specifically implemented through the following step 203b1.

[0175] Step 202b1: The first communication device sends a first request to the third communication device.

[0176] In an embodiment of the present application, the above-mentioned first request is used to request the third communication device to generate a first strategy, and the first request includes at least one of the following: first information, an identifier of the first perception device, and description information of the second perception task.

[0177] In this embodiment of the present application, the third communication device may be a PCF network element.

[0178] Optionally, in an embodiment of the present application, the description information of the above-mentioned second perception task may include at least one of the following: the perception accuracy or perception resolution required for the second perception task, the perception task duration of the second perception task, the perception service type of the second perception task (temperature or humidity, etc.), the target area information where the second perception task occurs (at what location it occurs, or it can indicate the location at which the perception device perceives), the required perception access method, perception frequency, perception waveform parameters, perception mode, etc. of the second perception task.

[0179] In one implementation, the target area information may refer to the first sensing device being able to perform sensing operations under the target area information, for example, the target area information specifies the area that the first sensing device can sense; it may also refer to the first sensing device being able to sense objects within the location indicated by the target area information, for example, the first sensing device can only sense the movement speed of objects under cell ID=001, that is, the target area information is used to specify the sensing range. Alternatively, the target area information may also indicate the location range where the second information is available, for example, the second information provides a variety of sensing configuration parameters, but these parameters may be specified to be configured only by the first sensing device under the target area information. In other words, the target area information specifies the location area used by the second information.

[0180] Step 202b2: The third communication device receives the first request sent by the first communication device, and generates a first policy according to the first request.

[0181] In the embodiment of the present application, the first strategy includes the second information.

[0182] Step 202b3: The third communication device sends the first policy to the first communication device.

[0183] Step 202b4: The first communication device receives the first policy sent by the third communication device.

[0184] Step 202b5: The first communication device sends the first strategy to the first perception device via the second communication device.

[0185] Step 203b1: The first perception device receives a first policy sent by the first communication device via the second communication device.

[0186] In an embodiment of the present application, the first strategy includes the second information. The first strategy is generated by the third communication device according to a first request received from the first communication device, the first request is used to request the third communication device to generate the first strategy, and the first request includes at least one of the following: the first information, the identifier of the first perception device, and the description information of the second perception task.

[0187] In one implementation, the first communication device may send a synesthesia policy control generation or modification request to the PCF network element: Npcf_SensingPolicyControl_Create / Modification request; the request carries the first information, the identifier of the first sensing device, and the description information of the second sensing task;

[0188] Then, the third communication device (PCF network element) sends a response to the first communication device, the response carries the first policy, and the first policy includes the second information, for example, the response is Npcf_SensingPolicyControl_Create / Modification response. It can be understood that the method of generating the synaesthesia policy by the PCF network element is borrowed here to send the second information and the perception configuration corresponding to the perception task.

[0189] It can be understood that in this implementation, the SF network element establishes a perception strategy to the PCF network element, and then the PCF sends the second information to the SF network element in the form of a perception strategy, and the SF network element then sends the second information to the terminal or base station (the first perception device). The method by which the SF network element first communication device sends the second information or the first strategy (to the terminal or base station) is the same as described above. The first communication device directly sends the first strategy to the terminal or base station, or it can send it to the terminal or base station through the AMF network element. The signaling sent can be an N2 message, a NAS message, or other types of control plane messages.

[0190] Optionally, in the embodiment of the present application, combined with Figure 6 ,like Figure 8 As shown, the above step 202b can be specifically implemented through the following steps 202b6 to 202b11, and the above step 203b can be specifically implemented through the following step 203b2.

[0191] Step 202b6: The first communication device sends a second request to the second communication device.

[0192] In an embodiment of the present application, the second request is used to request the second communication device to establish or modify the second policy, and the second request includes at least one of the following: the first information, the identifier of the first perception device, and the description information of the second perception task. The second request is used for the second communication device to trigger the establishment or modification of the second policy to the third communication device, and then send the established or modified second policy to the first perception device, and the established or modified second policy includes the second information.

[0193] It should be noted that the above-mentioned second communication device triggering the establishment or modification of the second policy to the third communication device can be understood as: the second communication device sends a request to the third communication device (i.e., the policy establishment or modification request described below) to request the third communication device to establish or modify the second policy, and then the third communication device sends the established or modified second policy to the second communication device, and the second communication device sends the established or modified second policy to the first perception device.

[0194] Step 202b7: The second communication device receives the second request sent by the first communication device, and sends a policy establishment or modification request to the third communication device.

[0195] Step 202b8: The third communication device receives the policy establishment or modification request sent by the second communication device, and establishes or modifies the second policy.

[0196] Step 202b9: The third communication device sends the established or modified second policy to the second communication device.

[0197] In the embodiment of the present application, the second strategy established or modified above includes second information.

[0198] Step 202b10: The second communication device receives the established or modified second policy sent by the third communication device.

[0199] Step 202b11: The second communication device sends the established or modified second policy to the first perception device.

[0200] Step 203b2: The first sensing device receives the second strategy for establishing or modifying sent by the second communication device.

[0201] In the embodiment of the present application, the second policy mentioned above may be an AM policy.

[0202] It can be understood that in this embodiment, the design method of reusing the AM policy, the first communication device sends a second request (first information, the identifier of the first perception device, and the description information of the second perception task) to the AMF network element of the second communication device. The information contained in the second request is used by the second communication device to establish or modify the AM policy. The second communication device sends a policy establishment or modification request through at least one of the following:

[0203] Npcf_AMPolicyControl_Create / Modification request

[0204] Then, the third communication device sends the second policy to the AMF network element of the second communication device by at least one of the following:

[0205] Npcf_AMPolicyControl_Create / Modification response

[0206] The second strategy includes second information, including: RFSP index.

[0207] That is to say, through the method of this embodiment, the SF network element can instruct the AMF network element to create or modify the AMpolicy, and the AM policy can send new sensing frequency information to the terminal or base station. The RFSP index here is used to select the frequency and perform the sensing task or sensing operation at the frequency.

[0208] In an embodiment of the present application, the second policy established or modified includes the second information. The second policy established or modified is triggered by the second communication device after receiving the second request from the first communication device, and the second policy is established or modified to the third communication device; the second request is used to request the second communication device to establish or modify the second policy, and the second request includes at least one of the following: the first information, the identifier of the first perception device, and the description information of the second perception task.

[0209] Step 204: The first sensing device performs a sensing configuration operation according to the second information to perform a second sensing task.

[0210] Optionally, in the embodiment of the present application, the above step 204 can be implemented by at least one of the following:

[0211] The first sensing device sets the sensing mode to the sensing mode indicated by the second information to perform the second sensing task;

[0212] The first sensing device sets the sensing frequency point to the sensing frequency point indicated by the second information to perform the second sensing task;

[0213] The first perception device sets the perception frequency bandwidth to the perception frequency bandwidth indicated by the second information to perform the second perception task;

[0214] The first sensing device sets the access mode to the access mode indicated by the second information to perform the second sensing task;

[0215] The first sensing device sets the transmission power, the receiving power, etc. according to the sensing accuracy or the sensing resolution requirement indicated in the second information to achieve the sensing accuracy or the sensing resolution requirement; or adjusts the bandwidth, the angular resolution, the antenna aperture, the time domain width, etc. of the sensing signal;

[0216] The first sensing device selects a sensing waveform to be transmitted, and the configuration of the sensing waveform is the configuration of the sensing waveform indicated by the second information.

[0217] The embodiment of the present application provides a method for determining and sending information, in which the first communication device can generate second information based on at least one of the perception capability information and the perception context information of the first perception device to indicate the device parameters or device configuration required for the second perception task that the first perception device needs to perform, so that the first communication device can send the second information to the first perception device, so that the first perception device performs the perception configuration operation to perform the second perception task that needs to be performed. In this solution, after determining the second perception task that needs to be performed, the first communication device determines the second information based on at least one of the perception capability information and the perception context information of the first perception device, that is, the perception configuration determined by the first perception device, and then the first communication device sends the perception configuration to the first perception device, so that the first perception device can accurately complete the second perception task according to the received required device parameters or device configuration, thereby improving the efficiency and accuracy of communication perception.

[0218] The following describes the interaction process of each communication device involved in the information determination and sending method of the embodiment of the present application through specific implementation methods (implementation method one to implementation method three).

[0219] Implementation method 1: Sending process of second information (hereinafter referred to as perception configuration) 1.1. Fig. 9 As shown, the process of sending the perception configuration of the base station includes the following steps 20 to 23.

[0220] Step 20: The SF network element receives a sensing request and generates a sensing task according to the sensing request.

[0221] The sensing request is used to request to perform a sensing task or a sensing operation. For example, terminal A requests to perform temperature sensing of a target area.

[0222] Step 21: The SF network element generates a sensing configuration according to at least one of the sensing capability information and the sensing context information of the sensing device.

[0223] Among them, the SF network element needs to first determine which terminals, base stations and / or core network elements are to participate in this perception task according to this perception task, then the SF will determine the candidate perception devices according to at least one of the perception capability information and perception context information of the terminal, base station and / or core network element. After determining the perception device, the SF network element generates the perception configuration.

[0224] It should be noted that the SF network element can execute step 22a, or can execute steps 22b1 and 22b2 to realize the sending of the perception configuration (ie, sending the perception configuration to the base station).

[0225] Step 22a: The SF network element directly sends the sensing configuration to the base station.

[0226] Step 22b1, the SF network element first sends the perception configuration to the AMF network element.

[0227] Exemplarily, the SF network element can send the perception configuration to the AMF network element through Namf_Communication_N1N2MessageTransfer.

[0228] Step 22b2: The AMF network element then sends the perception configuration to the base station via the N2 message.

[0229] Exemplarily, the above-mentioned N2 message may be an AMF CONFIGURATION UPDATE message, or a DOWNLINK RAN CONFIGURATION TRANSFER message.

[0230] Step 23: The base station adjusts the equipment according to the sensing configuration to perform the sensing task or sensing operation.

[0231] The base station adjusts the device according to the sensing configuration, including at least one of the following:

[0232] The base station sets the sensing mode of the base station to the sensing mode indicated by the sensing configuration, such as the self-transmitting and self-receiving mode;

[0233] The base station sets the sensing frequency point / sensing bandwidth of the base station to the sensing frequency point / sensing bandwidth indicated by the sensing configuration, so as to send a sensing waveform with a certain width at this frequency point;

[0234] The base station sets the access mode of the base station to the access mode indicated by the sensing configuration, for example, the base station is set to sense through 5G access or non-3GPP access. Using different access modes will also lead to different sensing measurement results;

[0235] The sensing waveform selected by the base station is the sensing waveform indicated by the sensing configuration, for example, what wavelength, what frequency, what waveform, etc., is the sensing waveform;

[0236] The base station sets the transmit power or receive power of the base station according to the requirements of the sensing resolution or sensing accuracy, and sets the transmit power, receive power, etc. to achieve the requirements of the sensing accuracy or sensing resolution; or adjusts the bandwidth, angle resolution, antenna aperture, time domain width, etc. of the sensing signal;

[0237] When the location to be sensed by the base station is the same as the location indicated in the target area information, the base station uses the second information to perform a sensing configuration operation;

[0238] The base station determines the duration of a sensing task according to the duration of the sensing task;

[0239] The base station determines the device that cooperates with it in the sensing operation according to the designated sensing node information, for example, the base station receives the echo signal of which designated sensing node.

[0240] 1.2, such as Fig.10 As shown, the process of sending the terminal's perception configuration includes the following steps 30 to 33.

[0241] Step 30 is the same as the above step 20, and step 31 is the same as the above step 21.

[0242] It should be noted that the SF network element may execute step 32a, or may execute steps 32b1 and 32b2, to implement the sending of the perception configuration (ie, sending the perception configuration to the terminal).

[0243] Step 32a: The SF network element directly sends the sensing configuration to the terminal.

[0244] It should be noted that here the SF network element directly sends the perception configuration to the terminal, including the SF network element directly sending it to the terminal without passing through any device, and also includes sending it to the terminal through the AMF network element. However, at this time, the AMF network element is equivalent to transparent transmission, and the AMF network element will not perform any processing on the perception configuration.

[0245] Step 32b1, the SF network element first sends the perception configuration to the AMF network element.

[0246] Exemplarily, the SF network element can send the perception configuration to the AMF network element through Namf_Communication_N1N2MessageTransfer.

[0247] Step 32b2: The AMF network element then sends the perception configuration to the terminal via a downlink NAS message (DL NAS message).

[0248] Step 33: The terminal adjusts the device according to the perception configuration to perform the perception task or perception operation.

[0249] It should be noted that the specific way in which the terminal adjusts the device according to the perception configuration is similar to the specific way in which the base station adjusts the device according to the perception configuration, see the description in the above step 23, and will not be repeated here.

[0250] It should be noted that for the description of the perception configuration, perception capability information and perception context information in the above steps 20 to 23 and steps 30 to 33, please refer to the description in the above embodiments and will not be repeated here.

[0251] Implementation method 2: Sending the perception configuration to the terminal or base station in the form of policy information

[0252] It should be noted that the second implementation mode can be understood as a specific implementation mode of the first implementation mode, that is, the sending of the perception configuration to the terminal or the base station can be specifically sent in the form of policy information.

[0253] like Fig.11 As shown, the process of sending the perception configuration of the terminal or base station includes the following steps 40 to 47.

[0254] Step 40: The SF network element determines that there is a sensing task, and determines the terminal or base station required for the sensing task.

[0255] It should be noted that after determining that the perception task requires a terminal or a base station, the SF network element may determine the perception configuration according to at least one of the perception capability information and the perception context information of the terminal or the base station.

[0256] Step 41: The SF network element sends a search request to the Binding Support Function (BSF) network element.

[0257] The above search request may be a Nbsf_Management_Discovery request. The above Nbsf_Management_Discovery request is used to request the BSF network element to search for the PCF network element that serves these terminals (ie, the terminals required for the sensing task).

[0258] Step 42: The BSF network element sends a search response to the SF network element.

[0259] The Nbsf_Management_Discovery response carries the identifier of the found PCF network element.

[0260] Step 43: The SF network element sends a request to the PCF network element to request the generation of a perception policy, and the request carries the perception configuration.

[0261] It should be noted that the request here is the same as the first request in the above embodiment, and the perception strategy here is the same as the first strategy in the above embodiment. For details, please refer to the description in the above embodiment, which will not be repeated here.

[0262] Optionally, the request here may be Npcf_SensingPolicyControl_Create / Modificationrequest, carrying the sensing configuration.

[0263] Step 44: The PCF network element sends a sensing policy to the SF network element, carrying the sensing configuration.

[0264] Step 45: The SF network element sends the perception policy including the perception configuration to the AMF network element.

[0265] Step 46: The AMF network element sends the sensing configuration to the base station.

[0266] Among them, the AMF network element sends the perception configuration to the base station through the N2 message (N2 message update RAN).

[0267] Step 47: The AMF network element sends the perception configuration to the terminal.

[0268] Among them, the AMF network element sends the perception configuration to the terminal through a downlink NAS message, which is also a UCU process, UE configuration update command, which is also a downlink NAS message.

[0269] It should be noted that both step 46 and step 47 may be performed, or one of step 46 and step 47 may be performed, so that the terminal or base station may use the perception configuration to perform the perception configuration operation to perform the perception task (i.e., the second perception task mentioned above).

[0270] It should be noted that for the description of the perception configuration, perception capability information, perception context information and perception configuration operation in the above steps 40 to 47, please refer to the description in the above embodiments, which will not be repeated here.

[0271] Implementation method 3: Reusing AM policy to send perception configuration

[0272] It should be noted that the difference between implementation mode three and the above-mentioned implementation mode two is that implementation mode two is a new perception strategy, and implementation mode three here can reuse the access mobility management policy (AM policy). For example, the AM policy can be reused for perception frequency selection, access method, etc.

[0273] like Fig.12 As shown, the process of sending the perception configuration of the terminal or base station includes the following steps 50 to 57.

[0274] Steps 50 to 52 are the same as steps 40 to 42 described above.

[0275] Step 53: The SF network element sends a request to the AMF network element to request the AMF network element to establish or modify an AM policy. The request carries the perception configuration.

[0276] It should be noted that the request here is the same as the second request in the above embodiment, and the AM strategy here is the same as the second strategy in the above embodiment. For details, please refer to the description in the above embodiment, which will not be repeated here.

[0277] The request here may be Namf_Communication_N1N2MessageTransfer.

[0278] Step 54: The AMF network element triggers a policy establishment or modification request to the PCF network element.

[0279] It can be understood that the AMF network element can trigger the establishment or modification of the AM policy to the PCF network element, that is, the AMF network element sends a request (i.e., a policy establishment or modification request) to the PCF network element to request the PCF network element to establish or modify the AM policy, and then the PCF network element sends the established or modified AM policy to the AMF network element, and the AMF network element sends the established or modified AM policy to the terminal or base station.

[0280] The policy creation or modification request here may be Npcf_AMPolicyControl_Create / Modification request.

[0281] Step 55: The PCF network element sends the established or modified AM policy to the AMF network element, carrying the perception configuration.

[0282] Step 56: The AMF network element sends the sensing configuration to the base station.

[0283] Among them, the AMF network element sends the perception configuration to the base station through the N2 message (N2 message update RAN).

[0284] Step 57: The AMF network element sends the perception configuration to the terminal.

[0285] Among them, the AMF network element sends the perception configuration to the terminal through a downlink NAS message, which is also a UCU process, UE configuration update command, which is also a downlink NAS message.

[0286] It should be noted that both step 56 and step 57 may be performed, or one of step 56 and step 57 may be performed, so that the terminal or base station may use the perception configuration and perform the perception configuration operation to perform the perception task (i.e., the second perception task mentioned above).

[0287] It should be noted that for the description of the perception configuration, perception capability information, perception context information and perception configuration operation in the above steps 50 to 57, please refer to the description in the above embodiments, which will not be repeated here.

[0288] Each of the above-mentioned method embodiments, or various possible implementation methods in each method embodiment, can be executed separately, or any two or more of them can be executed in combination with each other. The specific implementation method can be determined according to actual usage requirements, and the embodiments of the present application do not limit this.

[0289] The information determination and sending method provided in the embodiment of the present application can be executed by an information determination and sending device. In the embodiment of the present application, the information determination and sending device performing the information determination and sending method is taken as an example to illustrate the information determination and sending device provided in the embodiment of the present application.

[0290] Fig.13 A possible structural diagram of the information determination and sending device involved in the embodiments of the present application is shown. Fig.13 As shown, the information determination and sending device 60 may include: a generating module 61 and a sending module 62 .

[0291] The generating module 61 is used to generate the second information according to the first information; wherein the first information includes at least one of the sensing capability information of the first sensing device and the sensing context information of the first sensing device, the sensing capability information is used to indicate the sensing capability of the first sensing device, and the sensing context information is used to indicate the information related to the first sensing task currently performed by the first sensing device. The sending module 62 is used to send the second information generated by the generating module 61 to the first sensing device, the second information is used to indicate the device parameters or device configuration required for the first sensing device to perform the second sensing task.

[0292] An embodiment of the present application provides an information determination and sending device.
