[0080] For ease of understanding, the following describes some aspects of the embodiments of this application:

[0081] I. Integrated communication and sensing or integrated communication and sensing.

[0082] Wireless communication and radar sensing have been developing in parallel, but with limited overlap. They share many commonalities in signal processing algorithms, equipment, and to some extent, system architecture. In recent years, the coexistence, cooperation, and joint design of these two systems have attracted increasing attention from researchers.

[0083] Early research extensively explored the coexistence of communication and radar systems, focusing on developing effective interference management techniques to enable two separately deployed systems to operate smoothly without interfering with each other. While radar and communication systems may be located in the same place, or even physically integrated, they transmit two different signals in the time / frequency domain. They cooperate by sharing the same resources to minimize interference between them when operating simultaneously. Corresponding measures include beamforming, cooperative spectrum sharing, primary and secondary spectrum sharing, and dynamic coexistence. However, effective interference cancellation typically places stringent requirements on node mobility and information exchange between nodes, thus limiting practical improvements in spectral efficiency. Since interference in coexisting systems arises from the transmission of two independent signals, it is natural to ask whether we can simultaneously use a single transmitted signal for both communication and radar sensing. Radar systems often use specially designed waveforms, such as short pulses and chirps, to achieve high-power radiation and simplify receiver processing. However, these waveforms are not essential for radar detection; passive radar or passive sensing, which uses different radio signals as sensing signals, is a good example.

[0084] Machine learning, particularly deep learning, has further enhanced the potential of using non-dedicated radio signals for radar sensing. With these technologies, traditional radar is moving towards more general wireless sensing. Here, wireless sensing can broadly refer to retrieving information from received radio signals, rather than communication data modulated onto signals at the transmitter. For wireless sensing related to target location, common signal processing methods can be used to estimate dynamic parameters such as target signal reflection delay, angle of arrival (AOA), angle of departure (AOD), and Doppler. For sensing target physical characteristics, this can be achieved through measuring devices, objects, or inherent pattern signals. These two sensing methods can be referred to as sensing parameter estimation and pattern recognition, respectively. In this sense, wireless sensing refers to more general sensing technologies and applications using radio signals.

[0085] Integrated Sensing and Communication (ISAC) has the potential to integrate wireless sensing into large-scale mobile networks, referred to here as Perceptive Mobile Networks (PMNs). PMNs can evolve from current 5G mobile networks and are expected to become ubiquitous wireless sensing networks while providing stable, high-quality mobile communication services. They can be built on top of existing mobile network infrastructure without requiring significant changes to network structure and equipment. This will unlock the full potential of mobile networks and avoid the high infrastructure costs of building new wide-area wireless sensing networks separately. With expanded coverage, the integrated communication and sensing capabilities are expected to enable many new applications. Perceptive Mobile Networks can simultaneously provide communication and wireless sensing services, and due to their large broadband coverage and robust infrastructure, they have the potential to become a ubiquitous wireless sensing solution. Their coordinated communication and sensing capabilities will improve the productivity of our society and help foster a large number of new applications that existing sensor networks cannot effectively realize. Some early work on passive sensing using mobile signals has already demonstrated its potential. Examples include traffic monitoring, weather forecasting, and rainfall remote sensing based on GSM radio signals. Sensing mobile networks can be widely applied to communication and sensing in transportation, communications, energy, precision agriculture, and security sectors, where existing solutions are either infeasible or inefficient. It can also complement existing sensor networks, possessing unique day / night operation capabilities and the ability to penetrate fog, foliage, and even solid objects.

[0086] In mobile communication networks, base stations (including one or more TRPs on the base station) and user equipment (UE) (including one or more sub-arrays / panels on the UE) can act as sensing nodes participating in ISAC services. By sending and receiving sensing signals between nodes, sensing of a certain area or a specific target can be achieved. The sensing signals can be signals that do not contain transmitted information, such as existing LTE / NR synchronization and reference signals, including synchronization signals and physical broadcast channel (PBCH block, SSB) signals, channel state information-reference signals (CSI-RS), demodulation reference signals (DMRS), sounding reference signals (SRS), positioning reference signals (PRS), and phase-tracking reference signals (PTRS), etc. They can also be radar-common continuous wave (CW) or frequency modulated continuous wave (FMCW). These signals can be CW (Current Wideband Gaussian Wound), FMCW (Frequency Multi-Channel Wave), and ultra-wideband Gaussian pulses; they can also be newly designed dedicated sensing signals with good correlation characteristics and low peak-to-average power ratio (PAPR), or newly designed integrated sensing signals that carry certain information and have good sensing performance. The above sensing signals will be referred to as the first signal below.

[0087] Based on whether the sensing nodes are the same device, there are two sensing methods: A transmits and B receives, and A transmits and receives independently. A transmits and B receives means that sensing node A and sensing node B are not the same device and are physically separated. A transmits and receives independently means that the sending and receiving of sensing signals are performed by the same device, and sensing node A senses by receiving the echo of its own transmitted signal. Hereinafter, the above-mentioned A transmits and receives independently sensing is referred to as the first sensing method, and the corresponding sensing method is referred to as the first sensing method; A transmits and B receives sensing is referred to as the second sensing method, and the corresponding sensing method is referred to as the second sensing method.

[0088] Switching between perception modes:

[0089] Switching between sensing modes in a mobile communication network can be divided into two scenarios: switching from the second sensing mode to the first sensing mode, and switching from the first sensing mode to the second sensing mode. Figure 2aThis illustrates the scenario where the second sensing mode switches to the first sensing mode. Figure 2b The diagram illustrates the scenario of switching from the first sensing mode to the second sensing mode. Considering that the sensing nodes in the network may change before and after the switch, and that the sensing node after the switch may be a network-side device or a UE, each of the two switching scenarios has six combinations. Taking the switch from the second sensing mode to the first sensing mode as an example, the specific combinations are:

[0090] Switching to Scenario 1: The network-side devices and terminals perform sensing operations according to the second sensing method, switching to the network-side devices performing sensing operations according to the first sensing method;

[0091] Switching to Scenario 2: The network-side device and the network-side device perform sensing operations according to the second sensing method, and then switch to the network-side device performing sensing operations according to the first sensing method;

[0092] Switching to Scenario 3: The network-side devices and terminals perform sensing operations according to the second sensing method, switching to the terminals performing sensing operations according to the first sensing method;

[0093] Switching to Scenario 4: The terminal and the terminal perform sensing operations according to the second sensing method, switching to the terminal performing sensing operations according to the first sensing method;

[0094] Switching to Scenario 5: The terminal and terminal perform sensing operations according to the second sensing method, switching to the network-side device performing sensing operations according to the first sensing method;

[0095] Switching to Scenario 6: The network-side device and the network-side device perform sensing operations according to the second sensing method, and then switch to the terminal performing sensing operations according to the first sensing method.

[0096] in, Figure 3 Schematic diagrams are provided showing different combinations of switching from the second sensing mode to the first sensing mode. The network-side equipment is used as the baseline; to indicate that the sensing nodes may be different devices, base station A, base station B, and base station C, and UE A, UE B, and UE C are used for differentiation.

[0097] The perception mode switching method provided in this application will be described in detail below with reference to the accompanying drawings and through some embodiments and application scenarios.

[0098] Please see Figure 4 , Figure 4 This is a flowchart of a sensing mode switching method provided in an embodiment of this application. This method can be executed by a first node, such as... Figure 4 As shown, it includes the following steps:

[0099] Step 401: The first node obtains the first perception measurement result corresponding to each of the N candidate nodes. The first perception measurement result includes the result of the candidate node performing at least one perception measurement on the perception target using the first perception method. The signal transmitting node and the signal receiving node of the first perception method are the same node, and N is a positive integer.

[0100] In this embodiment, the signal transmitting node and the signal receiving node of the first sensing method are the same node. For example, sensing node C transmits a first signal and receives the first signal reflected by the sensing target to achieve sensing measurement. The sensing node may include a terminal or network-side device (e.g., a base station). Correspondingly, the signal transmitting node and the signal receiving node of the second sensing method are different nodes. For example, sensing node A transmits a first signal, and sensing node B receives the first signal reflected by the sensing target to achieve sensing measurement.

[0111] For example, the first node can select at least one target node from the N candidate nodes based on the first perception measurement results corresponding to the N candidate nodes, and send a switching confirmation message to the at least one target node to switch the perception mode of the perceived target from the second perception mode to the first perception mode.

[0112] The sensing mode switching method provided in this application involves a first node acquiring a first sensing measurement result corresponding to each of N candidate nodes, and based on the first sensing measurement result corresponding to each of the N candidate nodes, switching the sensing mode of the sensing target from the second sensing mode to the first sensing mode. This allows for switching the sensing mode of the sensing target when the state of the sensing target, the sensing environment, the location of the sensing node, or the available resources of the sensing node change, enabling the switched sensing mode to more accurately measure the sensing target and improving the accuracy of the sensing measurement results.

Otherwise, the first perception measurement result corresponding to each of the N candidate nodes can be omitted.

[0118] In some optional embodiments, the first node can determine whether to initiate a switch from the second sensing mode to the first sensing mode for the sensing target based on the switching measurement report. For example, if the measured value of at least one of the sensing measurements meets a first threshold condition or the measured value of at least one sensing performance evaluation index meets a second threshold condition, the first node can determine to initiate a switch from the second sensing mode to the first sensing mode for the sensing target; otherwise, it can not initiate a switch from the second sensing mode to the first sensing mode for the sensing target. If it is determined that a switch from the second sensing mode to the first sensing mode for the sensing target has been initiated, the first sensing measurement result corresponding to each of the N candidate nodes can be obtained.

[0119] This embodiment obtains the first perception measurement result corresponding to each of the N candidate nodes based on the switching measurement report. This allows for a more accurate decision on whether it is necessary to obtain the first perception measurement result corresponding to each of the N candidate nodes.

[0392] It should be noted that some aspects of this embodiment can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0393] To better understand this application, the following detailed explanation is based on different switching scenarios, and the perception operation performed using the first perception method will be referred to as the first perception, and the perception operation performed using the second perception method will be referred to as the second perception.

[0394] Scenario 1: The network-side device and the terminal perform sensing operations according to the second sensing method, and then switch to the network-side device performing sensing operations according to the first sensing method, that is, base station-UE second sensing, and switch to base station first sensing. The base station that performs second sensing before the handover is called the source base station, and the base station that performs first sensing after the handover is called the target base station. The UE in this handover scenario is the UE that performs second sensing before the handover.

[0395] Step 11: Perform handover measurements, which are divided into two cases: downlink sensing (i.e., source base station transmits signals, source terminal receives signals) and uplink sensing (i.e., source terminal transmits signals, source base station receives signals).

[0396] (1) Base station-UE is for downlink sensing:

[0397] The source base station sends a handover measurement request to the UE. After receiving the handover measurement request, the UE performs handover measurement and sends a handover measurement report back to the source base station.

[0398] or,

[0399] The core network equipment (e.g., a sensing function network element) sends a handover measurement request to the UE. Upon receiving the handover measurement request, the UE performs handover measurements and sends a handover measurement report back to the core network equipment. In some optional embodiments, the UE or the core network equipment sends a handover measurement report to the source base station.

[0400] In some alternative embodiments, before the UE performs handover measurements, the core network device or the source base station sends the handover measurement configuration information necessary for the handover measurement to the UE, or the handover measurement configuration information is included in the handover measurement request.

[0401] (2) Base station-UE is uplink sensing:

[0402] The source base station performs handover measurements. In some optional embodiments, the core network equipment or UE sends a handover measurement request to the source base station before the source base station performs handover measurements.

[0403] In some optional embodiments, before the source base station performs handover measurements, the core network device or UE sends the handover measurement configuration information necessary for the handover measurement to the source base station, or the handover measurement configuration information is included in the handover measurement request.

[0404] The switching of measurement configuration information can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0405] Optionally, step 11 above can be triggered based on a triggering event. The triggering event for step 11 can be referred to the relevant description in the foregoing embodiments, and will not be repeated here.

[0406] Step 12: The source base station decides whether to initiate a handover based on the handover measurement report.

[0407] Optionally, the source base station reports a handover measurement report to the core network equipment, which then decides whether to initiate a handover request. Alternatively, the core network equipment may decide whether to initiate a handover request based on the handover measurement report received from the UE.

[0408] If no switch is initiated, the subsequent processing can be to maintain or terminate the current second perception.

[0409] If a handover is initiated, the core network equipment or the source base station determines which node will switch to the first sensing mode, specifically in one of the following scenarios:

[0410] Scenario 1: The source base station decides to switch to the base station to perform the first sensing operation.

[0411] The source base station sends a first request message to at least one candidate base station. The first request message requests the first request message recipient to perform the second sensing after the sensing mode switch is completed.

[0412] Optionally, the source base station sends a first indication message to the core network equipment. The first indication message is to notify the recipient of the first indication message that the base station performs the first perception after the perception mode is switched.

[0413] Optionally, the source base station sends a second indication information to the UE, the second indication information being an instruction to the recipient of the second indication information to no longer participate in sensing after the sensing mode switch is completed.

[0414] Scenario 2: The core network equipment decides to switch to the base station to perform the first sensing operation.

[0415] The core network equipment sends a first request message to at least one candidate base station.

[0416] Optionally, the core network equipment sends a first indication message to the source base station.

[0417] Optionally, the core network equipment sends a second indication message to the UE.

[0418] Optionally, the candidate base station includes the source base station.

[0419] Scenario 3: The source base station decides to proactively switch to performing the first sensing operation. In this case, the source base station is a candidate base station.

[0420] The source base station sends a third indication message to the core network equipment. The third indication message is an instruction to the third indication message recipient. After the sensing mode switch is completed, the third indication message sender can perform the first sensing.

[0421] Optionally, case 3 also includes case 1.

[0422] Optionally, the source base station or core network equipment may include suggested first configuration information in the first request information. The first configuration information includes sensing parameter configuration information, used for configuring the sensing parameters for the candidate base station and the target base station to perform the first sensing operation.

[0423] Optionally, the first request information may include a soft handover request. Optionally, the first configuration information may also include soft handover parameter configuration information.

[0424] The first request information and the first configuration information mentioned above can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0425] In some optional embodiments, the candidate base stations can be determined based on first information about the candidate base stations. The first information can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0426] Step 13: The candidate base station decides whether to accept performing the first sensing operation after switching sensing modes. Specifically, this involves the following scenarios:

[0427] Scenario 1: If the candidate base station agrees, the following procedures will be executed sequentially:

[0428] 13-1) The candidate base station may configure the sensing parameters and perform the first sensing based on at least one of the first request information and the first configuration information.

[0429] 13-2) After performing at least one sensing measurement, the candidate base station sends a first response information to the source base station or core network equipment. The first response information is an instruction to the sender of the first request information. After the sensing mode is switched, the sender of the first response information agrees to perform the first sensing.

[0430] The first response information includes a first perception measurement result, which may include at least one of the following:

[0431] 1) The measured value and / or sensing result of at least one sensing measurement performed in the first sensing;

[0432] 2) Measurement results of at least one perceived performance evaluation indicator;

[0433] 3) Measured values ​​of communication quantities.

[0434] The aforementioned sensing measurements, sensing performance evaluation indicators, and communication measurements can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0435] Optionally, the first response information may also include:

[0436] The second configuration information is used to configure the sensing parameters for the target base station to perform the first sensing.

[0437] The second configuration information mentioned above can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0438] Optionally, if the first request information includes a soft handover request, and the candidate base station agrees to and supports the soft handover, the second configuration information may also include soft handover parameter configuration information.

[0439] 3-3) The source base station or core network equipment waits for the first response information of the candidate base station within a second preset time. Once the first response information sent by a candidate base station meets the first handover condition, the candidate base station is immediately selected as the sensing node to perform the first sensing after the handover, i.e., the target node.

[0440] The first switching condition mentioned above can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0441] Scenario 2: If the candidate base station disagrees, the candidate base station may optionally send a first rejection message to the sender of the first request message (source base station or core network equipment). The first rejection message is an instruction to the sender of the first request message that the sender of the first rejection message should not perform the first detection.

[0442] If no candidate base station agrees to perform the first sensing within the second preset time, the subsequent processing may be one of the following: i. The source base station or core network equipment re-determines the candidate base station; ii. Cancel the handover and maintain the current second sensing; iii. Terminate the current second sensing.

[0443] Step 14: After determining the target base station, the source base station or core network equipment sends a handover confirmation message to the target base station. This handover confirmation message is used to notify the recipient of the handover confirmation message that it will subsequently perform the first sensing operation.

[0444] Optionally, after the source base station or core network equipment determines the target base station, it sends a handover cancellation message to other candidate base stations besides the target base station. This handover cancellation message is used to notify other candidate sensing nodes to cancel the first sensing operation and release reserved sensing resources. Upon receiving the handover cancellation message, other candidate base stations release their reserved sensing resources.

[0445] Step 15: The target base station executes sensing services, and the UE releases sensing resources. Specifically, the following operations are performed:

[0446] 15-1) The target base station configures the sensing parameters based on at least one of the first request information, the first configuration information, and the second configuration information, and performs the first sensing.

[0447] 15-2) The UE or the UE and the source base station cease performing second sensing operations and release sensing resources. Depending on the differences between the sensing nodes before and after the handover, one of the following situations may occur:

[0448] 1) The sender of the first request information is the source base station, and the source base station and the target base station are not the same device:

[0449] The source base station sends a sensing end command to the UE. The source base station and the UE terminate the original sensing operation and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0450] Optionally, the source base station may send some or all of the historical measurement values ​​and / or historical sensing results, as well as prior information about the sensing target / area, to the target base station.

[0451] 2) The sender of the first request information is a core network device, and the source base station and the target base station are not the same device:

[0452] The core network equipment sends a sensing termination command to the source base station and the UE. The source base station and the UE terminate their original sensing operations and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0453] Optionally, the core network equipment may send some or all of the historical measurement values ​​and / or historical sensing results, as well as prior information about the sensing target / area, to the target base station.

[0454] 3) The sender of the first request information is a core network device, and the source base station and the target base station are the same device:

[0455] The core network equipment sends a sensing end command to the UE. The UE terminates its original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0456] Optionally, the core network equipment may send some or all of the historical measurement values ​​and / or historical sensing results, as well as prior information about the sensing target / area, to the target base station.

[0457] 15-3) After obtaining at least one sensing measurement result and / or sensing result, the target base station sends the sensing measurement result and / or sensing result to the source base station or core network equipment.

[0458] It should be noted that the sensing measurements before switching sensing methods in this switching scenario can be the same as or different from the sensing measurements after switching sensing methods.

[0459] Scenario 2: The network-side devices perform sensing operations according to the second sensing method, then switch to the network-side devices performing sensing operations according to the first sensing method, i.e., base station-to-base station second sensing, switching to base station first sensing. Before the sensing method switch, base station A and base station B perform second sensing. The base station sending the sensing signal is base station A, and the base station receiving the sensing signal is base station B. Base stations A and B performing second sensing before the switch are referred to as the source base station, and the base station performing first sensing after the switch is referred to as the target base station.

[0460] Step 21: Perform handover measurement. Base station A sends a handover measurement request to base station B. After receiving the handover measurement request, base station B performs the handover measurement and sends a handover measurement report back to base station A. Optionally, either base station A or base station B sends the handover measurement report to the core network equipment.

[0461] or,

[0462] The core network equipment (e.g., sensing function network elements) sends a handover measurement request to base station B. After receiving the handover measurement request, base station B performs handover measurements and sends a handover measurement report back to the core network equipment. Optionally, base station B or the core network equipment sends a handover measurement report to base station A.

[0463] or,

[0464] Base station B actively performs handover measurements and obtains a handover measurement report. Optionally, base station B sends the handover measurement report to the core network equipment or base station A.

[0465] Optionally, before base station B performs handover measurements, base station A or the core network equipment sends the necessary handover measurement configuration information to base station B; or, the handover measurement configuration information is included in the handover measurement request.

[0466] The switching of measurement configuration information can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0467] Optionally, step 21 above can be triggered based on a triggering event. The triggering event for step 21 can be referred to the relevant description in the foregoing embodiments, and will not be repeated here.

[0468] Step 2: Based on the handover measurement report, base station A decides whether to initiate a handover.

[0469] Optionally, base station A or base station B reports a handover measurement report to the core network equipment, which then decides whether to initiate a handover request.

[0470] If no switch is initiated, the subsequent processing can be to maintain or terminate the current second perception.

[0471] If a handover is initiated, the core network equipment or the source base station (including base station A and base station B) determines which node will switch to the first sensing mode, specifically in one of the following scenarios:

[0479] Optionally, the core network equipment sends a first indication message to base station A and / or base station B.

[0480] Optionally, the candidate base station includes at least one of base station A and base station B.

[0481] Scenario 4: Base station A decides to proactively switch to performing first-sensing. Base station A sends third-indication information to base station B and / or core network equipment. In this case, base station A is a candidate base station.

[0482] Optionally, case 4 may also include case 1.

[0483] Scenario 5: Base station B decides to proactively switch to performing first-sensing. Base station B sends third-instruction information to base station A and / or core network equipment. In this case, base station B is a candidate base station.

[0484] Optionally, case 5 may also include case 2.

[0485] Optionally, the source base station or core network equipment may include suggested first configuration information in the first request information.

[0486] Optionally, the first request information may include a soft handover request. Optionally, the first configuration information may further include soft handover parameter configuration information.

[0487] Step 3: The candidate base station decides whether to accept performing the first sensing after switching sensing modes.

[0488] Scenario 1: If the candidate base station agrees, the following procedures will be executed sequentially:

[0489] 23-1) Based on the first request information, the candidate base station configures the sensing parameters and performs the first sensing.

[0490] 23-2) After performing at least one sensing measurement, the candidate base station sends a first response message to the source base station or core network equipment.

[0491] The first response information can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0492] 23-3) The source base station or core network equipment waits for the first response information of the candidate base station within a second preset time. Once the first response information sent by a candidate base station meets the first handover condition, the candidate base station is immediately selected as the sensing node to perform the first sensing after the handover.

[0493] Optionally, the first response information may also include:

[0494] The second configuration information is used to configure the sensing parameters for the target base station to perform the first sensing.

[0495] The second configuration information mentioned above can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0496] Optionally, if the first request information includes a soft handover request, and the candidate base station agrees to and supports the soft handover, the second configuration information may also include soft handover parameter configuration information.

[0497] Scenario 2: If the candidate base station disagrees, the candidate base station may optionally send a first rejection message to the sender of the first request message (source base station or core network equipment).

[0498] If no candidate base station agrees to perform the first sensing within the second preset time, the subsequent processing may be one of the following: i. The source base station or core network equipment re-determines the candidate base station; ii. Cancel the handover and maintain the current second sensing; iii. Terminate the current second sensing;

[0499] Step 24: This step is the same as step 14 above, and will not be repeated here.

[0500] Step 25: The target base station executes sensing services, and at least one source base station (base station A and / or base station B) releases sensing resources. Specifically, the following operations are performed:

[0501] 25-1) The target base station configures the sensing parameters based on at least one of the first request information, the first configuration information, and the second configuration information, and performs the first sensing.

[0502] 25-2) The source base station (base station A and / or base station B) ceases to perform the second sensing operation and releases sensing resources. Depending on the differences in the sensing nodes before and after the handover, one of the following scenarios may occur:

[0503] 1) The sender of the first request information is base station A, and base station A and the target base station are not the same device:

[0504] Base station A sends a sensing termination command to base station B. Base station A and base station B terminate their original sensing operations and release the resources occupied by sensing (including time and frequency resources, antenna port resources, etc.).

[0505] Optionally, base station A may send some or all of the historical measurement values ​​and / or historical sensing results, as well as prior information about the sensing target / area, to the target base station.

[0506] 2) The sender of the first request information is a core network device, and the source base station and the target base station are not the same device:

[0507] The core network equipment sends a sensing termination command to base station A and base station B. Base station A and base station B terminate their original sensing operations and release the resources occupied by sensing (including time and frequency resources, antenna port resources, etc.).

[0508] Optionally, the core network equipment may send some or all of the historical measurement values ​​and / or historical sensing results, as well as prior information about the sensing target / area, to the target base station.

[0509] 3) The sender of the first request information is the core network equipment, and base station A and the target base station are the same equipment:

[0511] Optionally, the core network equipment may send some or all of the historical measurement values ​​and / or historical sensing results, as well as prior information about the sensing target / area, to the target base station.

[0512] 4) The sender of the first request information is the core network equipment, and base station B and the target base station are the same equipment:

[0513] The core network equipment sends a sensing termination command to base station A. Base station A terminates its original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0514] Optionally, the core network equipment may send some or all of the historical measurement values ​​and / or historical sensing results, as well as prior information about the sensing target / area, to the target base station.

[0515] 25-3) After obtaining at least one sensing measurement result and / or sensing result, the target base station sends the sensing measurement result and / or sensing result to the source base station or core network equipment.

[0516] It should be noted that the sensing measurements before switching sensing methods in this switching scenario can be the same as or different from the sensing measurements after switching sensing methods.

[0517] Scenario 3: The network-side equipment and terminal perform sensing operations according to the second sensing method, then switch to the terminal performing sensing operations according to the first sensing method, i.e., base station-UE second sensing, switching to UE first sensing. Before the sensing method switch, the base station and UE are performing second sensing. The UE performing second sensing before the switch is called the source UE, and the UE performing first sensing after the switch is called the target UE. The base station performing second sensing before the switch is called the source base station, and the access base station of the target UE is called the target access base station.

[0518] Step 31: This step is the same as step 11 above, and will not be repeated here.

[0519] Step 32: The source base station decides whether to initiate a handover based on the handover measurement report;

[0520] or

[0521] The source base station reports a handover measurement report to the core network equipment, which then decides whether to initiate a handover request.

[0522] or

[0523] The core network equipment decides whether to initiate a handover request based on the handover measurement report received from the source UE.

[0524] If no switch is initiated, the subsequent processing can be to maintain or terminate the current second perception.

[0525] If a handover is initiated, the core network equipment or the source base station determines which node will switch to the first sensing mode, specifically in one of the following two scenarios:

[0526] Scenario 1: The source base station decides to switch to the UE to perform the first sensing operation.

[0527] The source base station sends a first request message to at least one candidate UE. Alternatively, the source base station may send a second request message to at least one candidate access base station, the second request message requesting the recipient of the second request message (i.e., the candidate access base station) to find a candidate UE and perform second sensing after the sensing mode switch is completed. Further, the candidate access base station sends the first request message to at least one candidate UE.

[0528] Optionally, the source base station sends a fourth indication message to the core network equipment. The fourth indication message is to notify the recipient of the fourth indication message that the UE performs the first perception after the perception mode is switched.

[0529] Optionally, the candidate UE includes the source UE.

[0530] Scenario 2: The core network equipment decides to switch to the UE to perform the first perception mode.

[0531] The core network equipment sends a first request message to at least one candidate UE. This can be achieved by: the core network equipment sending a second request message to at least one candidate access base station, which in turn sends the first request message to at least one candidate UE.

[0532] Optionally, the core network equipment sends a second indication message to the source base station and / or the source UE.

[0533] Optionally, the candidate access base station includes the source base station.

[0534] Scenario 3: The source UE decides to actively switch to first-sensor mode. In this case, the source UE is a candidate UE.

[0535] The source UE sends third indication information to the source base station and / or core network equipment.

[0536] Optionally, case 3 may also include case 1.

[0537] Optionally, the source base station or core network equipment may include suggested first configuration information in the first request information and the second request information.

[0538] Optionally, the first request information and the second request information may include a soft handover request.

[0539] The aforementioned candidate UE can be determined based on the first information of the candidate UE. The first information can be described in the relevant description of the foregoing embodiments, which will not be repeated here.

[0540] The aforementioned first request information can be described in the relevant description of the foregoing embodiments, and will not be repeated here.

[0541] Step 33: The candidate UE decides whether to accept performing the first perception after switching perception modes.

[0542] Scenario 1: If the candidate UE agrees, the following procedures will be executed sequentially:

[0543] 33-1) The candidate UE configures the perception parameters based on at least one of the first request information and the first configuration information, and performs the first perception.

[0544] 33-2) After performing at least one sensing measurement, the candidate UE sends a first response message to the source base station or the candidate access base station.

[0545] The content of the first response information can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0546] Optionally, the candidate access base station sends a second response message to the sender of the second request message (source base station or core network equipment). The second response message indicates to the sender of the second request message that, after the sensing mode switch is completed, there is a UE in the cell that agrees to perform the first sensing.

[0547] Optionally, the second response information includes part or all of the first response information.

[0548] Optionally, the candidate UE may provide suggested first configuration information in the first response information.

[0549] The aforementioned first configuration information can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0550] If the first request information and the second request information include a soft handover request, and the candidate UE agrees to and supports the soft handover, the first configuration information may optionally include soft handover parameter configuration information.

[0551] 3-3) The source base station or core network equipment waits for the first response information from the candidate UE within a second preset time. Optionally, the source base station or core network equipment waits for the second response information from the candidate access base station within a preset time.

[0552] Once the first response information sent by a candidate UE is received and the first handover condition is met, the candidate UE is immediately selected as the sensing node to perform the first sensing after the handover.

[0553] or,

[0554] Once a second response message from a candidate access base station is received that satisfies the first handover condition, the candidate UE that sent the first response message that satisfies the first handover condition under that candidate access base station is immediately selected as the sensing node to perform the first sensing after the handover.

[0555] Optionally, the first response information includes second configuration information. The second configuration information includes at least one of the following: the same as the first configuration information.

[0556] If the first request information includes a soft handover request, and the candidate UE agrees to and supports the soft handover, the second configuration information may optionally include soft handover parameter configuration information.

[0557] The first switching condition mentioned above can be found in the relevant descriptions of the foregoing embodiments, and will not be repeated here.

[0558] Scenario 2: If the candidate UE disagrees, the candidate UE may optionally send a first rejection message to the sender of the first request message (source base station or core network equipment).

[0559] Optionally, the candidate access base station sends a second rejection message to the sender of the second request message (source base station or core network equipment). The second rejection message indicates to the sender of the second request message that the UE accessing the cell should not perform the second perception.

[0560] If no candidate access base station agrees to perform the first sensing within the preset waiting time, the subsequent processing may be one of the following: i. The source base station or core network equipment re-determines the candidate UE; ii. The candidate access base station re-determines the candidate UE; iii. The source base station or core network equipment re-determines the candidate access base station, and the candidate access base station determines the candidate UE; iii. The handover is canceled, and the current second sensing is maintained; iv. The current second sensing is terminated.

[0561] Step 34: After the source base station or core network equipment determines the target UE, it sends a handover confirmation message to the target UE; or, the source base station or core network equipment sends a handover confirmation message to the target access base station, and the target access base station forwards the handover confirmation message to the target UE.

[0562] Optionally, after determining the target UE, the source base station or core network equipment sends a handover cancellation message to other candidate UEs besides the target UE; or, it sends a handover cancellation message to other candidate access base stations besides the target access base station, and the other candidate access base stations forward the handover cancellation message to other candidate UEs. After receiving the handover cancellation message, the other candidate UEs release the reserved sensing resources.

[0563] Step 35: The target UE executes sensing services, and the source base station releases sensing resources. Specifically, the following operations are performed:

[0564] 35-1) The target UE configures perception parameters and performs first perception based on at least one of the first request information, the second request information, the first configuration information, and the second configuration information.

[0565] 35-2) The source base station or both the source base station and the UE cease performing second sensing and release sensing resources. Depending on the differences in sensing nodes before and after the handover, one of the following situations may occur:

[0566] 1) The sender of the request information (including the first request information or the second request information) is the source base station, and the source UE and the target UE are not the same device:

[0567] The source base station sends a sensing termination command to the source UE. The source base station and the source UE terminate the original sensing operation and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0568] Optionally, the source base station sends some or all of the historical measurement values ​​and / or historical sensing results, and prior information of the sensing target / area to the target UE;

[0569] or,

[0570] The source base station sends some or all of the historical measurement values ​​and / or historical sensing results of the sensing measurement quantities, as well as prior information of the sensing target / area, to the target access base station. The target access base station then sends the historical measurement values ​​and / or historical sensing results of the sensing measurement quantities, as well as prior information of the sensing target / area, to the target UE.

[0571] 2) The sender of the request information (including the first request information or the second request information) is a core network device, and the source UE and the target UE are not the same device:

[0572] The core network equipment sends a sensing termination command to the source base station and the source UE. The source base station and the source UE terminate their original sensing operations and release the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0573] Optionally, the core network equipment may send some or all of the historical measurement values ​​and / or historical sensing results, as well as prior information about the sensing target / area, to the target UE.

[0574] 3) The sender of the request information (including the first request information or the second request information) is a core network device, and the source UE and the target UE are the same device:

[0575] The core network equipment sends a sensing termination command to the source base station. The source base station terminates its original sensing operation and releases the resources occupied by the sensing (including time and frequency resources, antenna port resources, etc.).

[0576] Optionally, the core network equipment may send some or all of the historical measurement values ​​and / or historical sensing results, as well as prior information about the sensing target / area, to the target UE.

[0577] 5-3) After obtaining at least one sensing measurement result and / or sensing result, the target UE sends the sensing measurement result and / or sensing result to the core network equipment or the source base station; or,

[0578] The target UE sends the sensing measurement results and / or sensing results to the target access base station, and the target access base station sends the sensing measurement results and / or sensing results to the core network equipment or the source base station.

[0579] It should be noted that the sensing measurements before switching sensing methods in this switching scenario can be the same as or different from the sensing measurements after switching sensing methods.

[0580] Scenario 4: The terminals switch from performing sensing operations in the second sensing mode to performing sensing operations in the first sensing mode. Specifically, the UE-UE second sensing transitions to UE first sensing. Before the sensing mode switch, UE A and UE B are performing second sensing. UE A is the one sending the sensing signal, and UE B is the one receiving the sensing signal. The access base station of the source UE is called the source access base station, and the UE performing first sensing after the switch is called the target UE. The access base station of the target UE is called the target access base station.

[0581] Step 41: Perform a switching measurement.

[0582] UE A sends a handover measurement request to UE B. Upon receiving the handover measurement request, UE B performs handover measurements and sends a handover measurement report back to UE A. Optionally, UE A or UE B sends the handover measurement report to the source access base station and / or core network equipment (e.g., sensing function network elements).

[0583] or,

[0584] The source access base station sends a handover measurement request to UE B. Upon receiving the handover measurement request, UE B performs handover measurements and sends a handover measurement report back to the source access base station. Optionally, UE B or the source access base station sends a handover measurement report to the core network equipment and / or UE A.

[0585] or,

[0586] The core network equipment (e.g., a sensing function network element) sends a handover measurement request to UE B. After receiving the handover measurement request, UE B performs handover measurements and sends a handover measurement report back to the core network equipment. Optionally, the core network equipment sends a handover measurement report to the source access base station and / or UE A.

[0587] In some optional embodiments, before UE B performs handover measurements, any one of UE A, the source access base station, or the core network equipment sends the necessary handover measurement configuration information to UE B; or, the handover measurement configuration information is included in the handover measurement request.

[0588] The switching of measurement configuration information can be referred to the relevant descriptions in the foregoing embodiments, and will not be repeated here.

[0589] Optionally, step 41 above can be triggered based on a triggering event.

[0590] The triggering event of step 41 may include at least one of the following:

[0591] 1) The state of the target is perceived to have changed (state includes position, velocity, etc.);

[0592] 2) The locations of UE A and / or UE B change;

[0593] 3) Changes in transmission distance between UE A and UE B;

[0594] 4) Sensing changes in the surrounding environment (such as the appearance of obstructions);

[0595] 5) The sensing measurements acquired by UE B reach a preset threshold; for example, at least one of the sensing signal received power, sensing SNR, sensing SINR, distance / velocity / angle measurement values, etc., meets the preset handover threshold value.

[0596] 6) The communication measurement data acquired by UE B reaches the preset threshold;

[0597] 7) The communication measurement between UA A and / or UE B and the source access base station reaches the preset threshold.

[0598] 8) Changes in available sensing resources for UE A and / or UE B; for example, if other high-priority sensing / communication / sensing integrated services suddenly appear, it is necessary to assess whether to initiate a sensing handover process based on the remaining available sensing resources.

[0599] Step 42: The source access base station or core network equipment decides whether to initiate a handover based on the handover measurement report.

[0600] If no switch is initiated, the subsequent processing can be to maintain or terminate the current second perception.

[0601] If a handover is initiated, any one of the core network equipment, the source access base station, or the source UE (including UE A and UE B) will determine which node will switch to the first sensing mode, specifically in one of the following scenarios:

[0602] Scenario 1: The source access base station decides to switch to the UE to perform the first perception.

[0603] The source access base station sends a first request message to at least one candidate UE. Alternatively, the source access base station may send a second request message to at least one candidate access base station. The candidate access base station sends the first request message to at least one candidate UE.

[0604] Optionally, the source access base station sends a fourth indication message to the core network equipment.

[0605] Optionally, the candidate UE includes the source UE.

[0606] Scenario 2: The core network equipment decides to switch to the UE to perform the first perception mode.

[0607] The core network equipment sends a first request message to at least one candidate UE. This can be achieved by: the core network equipment sending a second request message to at least one candidate access base station, which in turn sends the first request message to at least one candidate UE.

Alternatively, the source access base station or core network equipment sends a handover confirmation message to the target access base station, and the target access base station forwards the handover confirmation message to the target UE.

[0639] Optionally, after determining the target UE, the source access base station or core network equipment sends a handover cancellation message to other candidate UEs besides the target UE; or, it sends a handover cancellation message to other candidate access base stations besides the target access base station, and the other candidate access base stations forward the handover cancellation message to other candidate UEs.

[0666] Scenario 5: The terminal and terminal perform sensing operations according to the second sensing method, then switch to the network-side device performing sensing operations according to the first sensing method, i.e., UE-UE second sensing, switching to base station first sensing. Before the sensing method switch, UE A and UE B are performing second sensing. The UE sending the sensing signal is UE A, and the UE receiving the sensing signal is UE B.
