[0094] In some embodiments, wireless signals can be used not only for data transmission but also for sensing functions, i.e., wireless sensing. A wireless signal transmitter can emit radio waves, and a wireless signal receiver can receive them. During the transmission of radio waves, the transmission may be blocked by objects (hereinafter referred to as reflectors), resulting in wireless transmission effects such as reflection, diffraction, transmission, phase changes, Doppler shift, and signal intensity changes. The wireless signal receiver receives the radio waves and compares the transmitted and received signals, or records the historical changes in the received signal, thereby obtaining information about the reflectors.

[0095] In some embodiments, the information of the reflector may include at least one of the following: coordinate information, such as coordinates, distance, horizontal angle, vertical angle, etc., relative to the wireless signal receiver; speed information, such as moving speed, moving direction, etc., relative to the wireless signal receiver; behavior pattern information, such as movement information such as running, walking, approaching, falling, swinging, etc., or weather information such as rain, snow, etc., or traffic information such as congestion, accidents, etc.

[0096] In some embodiments, in a wireless network (such as a cellular network), the wireless signal transmitter can be at least one of the following: a base station; a transmission / reception point (TRP); a wireless access point, such as a WiFi access point (AP); or a terminal.

[0097] In some embodiments, the wireless signal receiver may be at least one of the following: a base station; a transmission / reception point (TRP); a wireless access point; or a terminal.

[0098] In some embodiments, the wireless signal transmitter and the wireless signal receiver may be from the same device or different devices. For example: (1) Base station A is a wireless signal transmitter and base station B is a wireless signal receiver; (2) Base station A is a wireless signal transmitter and base station B is a wireless signal receiver; (3) Terminal A is a wireless signal transmitter and terminal B is a wireless signal receiver; (4) Terminal A is a wireless signal transmitter and terminal B is a wireless signal receiver; (5) Base station A is a wireless signal transmitter and terminal A is a wireless signal receiver; (6) Terminal A is a wireless signal transmitter and base station A is a wireless signal receiver.

[0099] In some embodiments, the node that receives sensing signals and performs sensing measurements can be referred to as a sensor. In some possible implementations, the sensor can be a base station or a terminal.

[0100] In some embodiments, perception can be divided into active perception and passive perception, depending on whether the perceiver itself sends a perception signal.

[0101] In some embodiments, a sensing function (SF) is considered. In some embodiments, the sensing function may support the following functions:

[0102] - How to perform perceived Quality of Service (QoS) parameter conversion;

[0103] -How to trigger awareness services;

[0104] -How to terminate the sensing service;

[0105] -How to control base stations or terminals to perform sensing based on sensing service requirements;

[0106] - How to efficiently process sensor measurement data;

[0107] - How to provide / open up the perception results.

[0108] In some embodiments, core network equipment may include a Sensing Function (SF). In some possible implementations, the SF can be split into a Sensing Control Plane Function (SF-C) and a Sensing User Plane Function (SF-U). These two sub-functions can be implemented separately in two network elements or centrally in one network element.

[0109] In other embodiments, the access network device may include a SF (Signal Provider). That is, the SF can be deployed as a central control node on the Radio Access Network (RAN) side.

[0110] The following section will briefly explain the 5G-based sensing architecture in conjunction with Figures 2A, 2B, and 2C.

[0111] Figure 2A is a schematic diagram of a sensing architecture according to an embodiment of the present disclosure. As shown in Figure 2A, the SF is deployed on the CN side, and the SF-C and SF-U are not separated. In this case, sensing control signaling between the SF and (R)AN can be transmitted through the Access and Mobility Management Function (AMF), and sensing control signaling between the SF and UE can also be transmitted through the AMF. Sensing measurement data acquired by the (R)AN and / or UE can be transmitted to the SF via the control plane or the user plane, wherein the user plane can be forwarded to the SF via the User Plane Function (UPF) or transmitted directly to the SF.

[0112] Specifically, NS1 is the interface between SF and AMF, used to transmit sensing control signaling and sensing measurement data. NS2 is the interface between SF and NEF, used to transmit signaling messages between SF and application function (AF) relayed through the Network Exposure Function (NEF), and to expose sensing results to the application function (AF). NS3 is the interface between SF and Unified Data Management (UDM), used for authentication or authorization. NS4 is the interface between SF and Network Data Analytics Function (NWDAF), used for sensing service-related artificial intelligence (AI) processing. NS5 is the interface between SF and Policy Control Function (PCF), used by SF to transmit sensing service requirements, Quality of Service (QoS) requirements, and sensing results to PCF, which then generates sensing service-related network policy and charging control (PCC) policies. NS6 is the interface between the SF and the Location Management Function (LMF), which can be used by the SF to obtain location-related information, such as the sensing area, the (R)AN information of the sensing target, and the location information of the sensed UE. NS7 is the interface between the SF and the UPF, which can be used to transmit sensing measurement data directly from the (R)AN to the SF, or to forward sensing measurement data to the SF via the UPF. N1 is the interface between the UE and the AMF, N2 is the interface between the (R)AN and the AMF, N5 is the interface between the PCF and the NEF, N8 is the interface between the AMF and the UDM, and N33 is the interface between the NEF and the AF. Interfaces N1, N2, N5, N8, and N33 can be used to transmit sensing service-related information, such as authentication information, sensing service type, sensing service quality requirements, sensing measurement data, and sensing results.

[0113] It should be noted that the above is merely an exemplary description and does not specifically limit this disclosure. For details not described in detail, please refer to relevant wireless sensing technologies, which will not be elaborated upon here.

[0114] Figure 2B is a schematic diagram of a sensing architecture according to an embodiment of this disclosure. As shown in Figure 2B, the SF is deployed on the CN side, and the SF-C and SF-U are separate. In this case, the SF-C can interact with the 5GC control plane network elements and is responsible for control plane message transmission. The SF-U can be responsible for collecting and analyzing the sensing measurement data acquired by the UE and / or (R)AN, obtaining sensing results, and making the sensing results available to the UE or applications. Sensing control signaling between the SF-C and (R)AN can be transmitted through the AMF, and sensing control signaling between the SF-C and the UE can also be transmitted through the AMF. The sensing measurement data acquired by the (R)AN and / or UE can be forwarded to the SF-U via the UPF or directly transmitted to the SF-U.

[0115] NS7 is the interface between SF-C and SF-U, which can be used to transmit sensing processing strategies, sensing results, etc. NS8 is the interface between SF-U and UPF. The other interfaces shown in Figure 2B have similar functions to the corresponding interfaces shown in Figure 2A, and will not be described in detail here.

[0116] Figure 2C is a schematic diagram of a sensing architecture according to an embodiment of the present disclosure. As shown in Figure 2C, the SF is deployed on the RAN side, and the SF can act as a central control node. In this case, the SF can directly establish a connection with the (R)AN, and the SF can be responsible for functions such as sensing authorization, capability interaction, network element selection, control, and data processing.

[0117] The NS1 interface serves as the interface between the SF and (R)AN, and can be used to transmit sensing control plane signaling messages and sensing measurement data. The SF can also have interfaces with 5GC network elements such as the AMF, NEF, and NWDAF to control the AF to provide sensing service requirements to the SF through core network functions. For example, the NS2 interface can be the interface between the SF and the AMF, used to transmit signaling messages between the SF and other 5GC network elements or service requirements from the UE.

[0118] This disclosure does not impose any special restrictions on the communication methods between the SF and the base station, or between the SF and the UE.

[0119] In some embodiments, it is necessary to consider the continuity of sensing services when the terminal performs cell handover or cell reselection. For example, for a terminal in the Radio Resource Control (RRC connected) state, the terminal is performing sensing services. Due to the terminal's movement, the terminal may handover from the source cell to the target cell. In this case, it is necessary to consider whether the terminal can continue to perform sensing services after the cell handover. For example, for a terminal in the Radio Resource Control (RRC idle) or Radio Resource Control (RRC inactive) state, the terminal is performing sensing services. Due to the terminal's movement or poor signal quality, the terminal may perform cell reselection and reselect to another cell. In this case, it is necessary to consider whether the terminal can continue to perform sensing services after the cell reselection.

[0120] Figure 3 is an interactive schematic diagram illustrating a processing method for sensing services according to an embodiment of the present disclosure.

[0121] As shown in Figure 3, the processing methods for sensing services include:

[0122] Step S301: The terminal reports third information to the network device.

[0123] In some embodiments, the third information includes the terminal's historical trajectory and / or the terminal's projected trajectory. The terminal's projected trajectory includes the trajectory the terminal is likely to generate. For example, the terminal can determine its projected trajectory based on the navigation path it is currently referencing.

[0124] In some embodiments, the terminal reports third information to a sensing network element or an access network device. In one possible implementation, the access network device may include an access network device associated with a first region and / or an access network device associated with a second region. The first region is the region the terminal moves out of, and the second region is the region the terminal moves into after moving out of the first region.

[0125] In some embodiments, the network device receives third information reported by the terminal. In one possible implementation, the access network device and / or sensing network element receive the third information reported by the terminal.

[0126] In some embodiments, the network device configures a sensing area and / or an associated area of ​​a reference signal for the terminal based on third information reported by the terminal. The reference signal is used for sensing. In one possible implementation, the sensing area is configured by the access network device and / or the sensing network element. In another possible implementation, the associated area of ​​the reference signal is configured by the access network device and / or the sensing network element. In some embodiments, the network device configures the sensing area and / or the associated area of ​​the reference signal for the terminal according to sensing requirements. For example, based on car tracking, the network device can configure the area traversed by the vehicle's movement route as the sensing area and / or the associated area of ​​the reference signal.

[0127] In some embodiments, the network device configures the sensing area and / or the associated area of ​​the reference signal for the terminal through RRC messages, system messages, etc.

[0128] In some embodiments, the sensing area represents at least one of the following: when the terminal is located within the sensing area, sensing services are performed; the terminal senses a target located within the sensing area.

[0129] In some embodiments, the sensing area includes a list of physical cell identifiers (PCIs) / cell global identifiers (CGIs).

[0130] In some embodiments, the sensing area includes a geographic area, such as a geographic area represented by coordinates.

[0131] In some embodiments, the terminal obtains a sensing area and / or an associated area of ​​a reference signal configured by the network device. In some possible implementations, the terminal receives an RRC message sent by the network device, the RRC message including the sensing area and / or the associated area of ​​the reference signal configured by the network device for the terminal. In some possible implementations, the terminal receives a system message sent by the network device, the system message including the sensing area and / or the associated area of ​​the reference signal configured by the network device for the terminal.

[0132] In some embodiments, the terminal device configures the associated area of ​​the sensing area and / or the reference signal for the terminal directly, rather than configuring the associated area of ​​the sensing area and / or the reference signal for the terminal.

[0133] In step S302, when the terminal moves out of the first area, it is determined whether to continue sensing services based on the configured sensing area and / or the associated area of ​​the reference signal.

[0134] In some embodiments, the first region belongs to at least one of the following: a sensing region; an associated region of a reference signal; or a serving cell of the terminal.

[0135] In some embodiments, the sensing mode used by the sensing service includes one of the following: UE-TRP sensing; and TRP-UE sensing. In one possible implementation, the UE-TRP sensing mode utilizes uplink communication signals transmitted by the terminal, such as uplink sensing reference signals (including reflected / diffracted signals); the access network device receives the uplink sensing reference signals transmitted by the terminal, thereby sensing the environment or targets between the terminal or the access network device. In one possible implementation, the access network device-TRP sensing mode utilizes downlink communication signals transmitted by the access network device, such as downlink sensing reference signals (including reflected / diffracted signals); the terminal receives the downlink sensing reference signals transmitted by the access network device, thereby sensing the environment or targets between the terminal or the access network device.

[0136] In some embodiments, the sensing mode used by the sensing service is terminal transmission and access network equipment reception, and the terminal stopping the sensing service includes the terminal stopping the transmission of reference signals used for sensing. In some embodiments, the sensing mode used by the sensing service is access network equipment transmission and terminal reception, and the terminal stopping the sensing service includes the terminal stopping the measurement of reference signals used for sensing.

[0137] In some embodiments, when the terminal moves out of the first area, the terminal stops the sensing service.

[0138] In some embodiments, the terminal manages the continuity of sensing services based on sensing areas. In one implementation, when the terminal moves out of the first area, it continues to sense services if the second area it moves into is a sensing area. Alternatively, when the terminal moves out of the first area, it stops sensing services if the second area it moves into is not a sensing area.

[0139] In some embodiments, since the terminal is performing sensing services in a first area, the terminal has already obtained sensing configuration information issued by the access network device associated with the first area. In some embodiments, the sensing configuration information can be used for one or more areas. In one possible implementation, the terminal's existing sensing configuration information is used for multiple areas (including the first area and the second area). When the terminal moves out of the first area, based on the fact that the second area the terminal moves into is a sensing area, the terminal continues to sense services based on the existing sensing configuration information. In one possible implementation, the terminal's existing sensing configuration information is used for one area (only the first area). When the terminal moves out of the first area, based on the fact that the second area the terminal moves into is a sensing area, the terminal requests new sensing configuration information from the sensing network element or the access network device associated with the second area. The new sensing configuration information is used for the second area, and the terminal continues to sense services based on the requested sensing configuration information.

[0140] In some embodiments, the terminal manages the continuity of sensing services based on the associated region of the reference signal. In one implementation, when the terminal moves out of the first region, it continues to sense services if the second region it moves into belongs to the associated region of the reference signal. Alternatively, when the terminal moves out of the first region, it stops sensing services if the second region it moves into does not belong to the associated region of the reference signal.

[0141] In some embodiments, the terminal manages the continuity of sensing services based on the signal quality of a reference signal. In one implementation, when the terminal moves out of a first area, it continues to sense services if a reference signal is measured in a second area it moves into. Alternatively, when the terminal moves out of the first area, it stops sensing services if no reference signal can be measured in the second area it moves into. Alternatively, when the terminal moves out of the first area, it continues to sense services if the signal quality of the reference signal in the second area it moves into is higher than a first threshold. Alternatively, when the terminal moves out of the first area, it stops sensing services if the signal quality of the reference signal in the second area it moves into is lower than a second threshold. The first threshold is greater than or equal to the second threshold. The embodiments of this disclosure do not limit the specific values ​​of the first and second thresholds.

[0142] In step S303, the terminal sends the first information to the network device.

[0143] In some embodiments, the first information is used to indicate the reason for determining whether to continue sensing services and / or the processing result of sensing services.

[0144] In some embodiments, the reasons for determining whether to continue sensing services include at least one of the following: the terminal moves out of the first area; the terminal moves into the second area; the terminal cannot measure the reference signal; the terminal has no measurement results available; the signal quality of the reference signal is lower than a second threshold; the terminal performs cell handover; the terminal performs cell reselection.

[0145] In some embodiments, the processing result of the sensing service includes one of the following: the terminal continues to sense the service; the terminal stops sensing the service.

[0146] In some embodiments, the terminal sends first information to a sensing network element, an access network device associated with a first region, or an access network device associated with a second region.

[0147] In some embodiments, a sensing network element, an access network device associated with a first area, or an access network device receives first information sent by a terminal.

[0148] In some embodiments, when the terminal is in the RRC connected state, the first information indicates that the processing result of the sensing service is that the terminal stops the sensing service, and the access network device and / or sensing network element selects other terminals to perform the sensing service.

[0149] In some embodiments, when the terminal is in an RRC idle state or an RRC inactive state, the first information indicates that the processing result of the sensing service is that the terminal stops the sensing service. If the access network device cannot receive the reference signal sent by the terminal, the access network device and / or the sensing network element selects another terminal to perform the sensing service. And / or, if the signal quality of the reference signal is lower than a second threshold value, the access network device and / or the sensing network element selects another terminal to perform the sensing service. And / or, if the access network device cannot receive the measurement result sent by the terminal, the access network device and / or the sensing network element selects another terminal to perform the sensing service.

[0150] In the above embodiments, for terminals in the RRC connected state, since the access network device can clearly know that the terminal has undergone cell handover, the access network device instructs the terminal to stop the sensing service according to the first message and can select other terminals to perform the sensing service. However, for terminals in the RRC idle state or RRC inactive state, since the access network device cannot clearly know that the terminal has undergone cell reselection, the access network device also needs to determine whether the reference signal is still valid. If it is invalid, it selects other terminals to perform the sensing service.

[0151] In some embodiments, the access network device sends fourth information to the sensing network element.

[0152] In some embodiments, the fourth information is used to indicate the reason for determining whether to continue the sensing service and / or the processing result of the sensing service. In one possible implementation, the terminal is in the RRC connected state; the fourth information is used to indicate that the terminal switches to the target cell, or the fourth information is used to indicate that the sensing service is stopped due to the terminal performing a cell handover. In one possible implementation, the terminal is in the RRC idle state or the RRC inactive state; the fourth information is used to indicate error information of the sensing service, or the fourth information is used to indicate that the access network device cannot obtain the measurement results of the terminal.

[0153] In some embodiments, the fourth information may also be used to indicate the cause of the error in the sensing service.

[0154] In some embodiments, the sensing network element receives fourth information sent by the access network device. For example, if the sensing network element requests the measurement results of the terminal from the access network device, but the access network device cannot obtain the measurement results of the terminal, then the access network device sends fourth information to the sensing network element.

[0155] In some embodiments, when the terminal is in the RRC connected state, the serving cell of the terminal indicates to the target cell that the terminal is conducting a sensing service. And / or, the serving cell of the terminal requests a reference signal from the target cell. And / or, the serving cell of the terminal requests sensing configuration information from the target cell.

[0156] In some embodiments, the terminal is in an RRC connected state, and the terminal's target cell provides a reference signal available to the terminal's serving cell. And / or, the terminal's serving cell provides sensing configuration information available to the terminal. In one possible implementation, the sensing configuration information includes, but is not limited to, the use case (tracking) of the sensing service, the quality of service, the period of the reference signal, and the location of time-frequency resources.

[0157] In some embodiments, the serving cell of the terminal sends the terminal's awareness configuration information for use in the target cell to the terminal. In some embodiments, the serving cell of the terminal sends the terminal's awareness configuration information for use in the target cell to the terminal via a HO command. The HO command is a type of RRC message used by the terminal to initiate cell handover upon receiving the HO command.

[0158] In some embodiments, a sensing network element or an access network device associated with the second area sends second information to the terminal. In some embodiments, the second information is used to instruct the terminal to continue sensing services in the second area. In some embodiments, the terminal receives the second information sent by the sensing network element or the access network device associated with the second area. For example, when the terminal moves out of the first area, it instructs the sensing network element to move into the second area; depending on whether the second area belongs to the sensing area and / or the associated area of ​​the reference signal, the sensing network element can trigger the terminal and the access network device associated with the second area to perform sensing services.

[0159] The communication method involved in the embodiments of this disclosure may include at least one of steps S301 to S303. For example, step S301 may be implemented as a standalone embodiment, step S302 may be implemented as a standalone embodiment, step S303 may be implemented as a standalone embodiment, step S301+S302 may be implemented as a standalone embodiment, and step S302+S303 may be implemented as a standalone embodiment, but is not limited thereto.

[0160] In some embodiments, steps S301, S302, and S303 may be performed in an interchangeable order or simultaneously.

[0161] In some embodiments, step S301 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0162] In some embodiments, step S303 is optional, and one or more of these steps may be omitted or substituted in different embodiments.

[0163] In some embodiments, other alternative embodiments described before or after the specification corresponding to FIG3 may be referred to.

[0164] Firstly, embodiments of this disclosure provide a method for processing sensing services. Figure 4 is a schematic flowchart illustrating a method for processing sensing services according to an embodiment of this disclosure. The method for processing sensing services shown in this embodiment can be executed by a terminal.

[0165] As shown in Figure 4, the processing method for sensing services may include the following steps:

[0166] In step S401, when the terminal moves out of the first area, it is determined whether to continue sensing services based on the sensing area configured for the terminal and / or the associated area of ​​the reference signal, where the reference signal is used for sensing.

[0167] In some embodiments, the sensing mode used by the sensing service may include one of the following: terminal transmission and access network device reception; access network device transmission and terminal reception.

[0168] For example, when UE#1 moves out of cell#1, UE#1 can determine whether to continue sensing services based on the configured sensing area and / or the associated area of ​​the reference signal. Wherein, if the sensing mode used for the sensing service is terminal transmission and access network equipment reception, the sensing agent is gNB#1, which is conducting the sensing service with UE#1; if the sensing mode used for the sensing service is access network equipment transmission and terminal reception, the sensing agent is UE#1. It should be noted that in the embodiments shown above, the first area being cell#1 is merely an exemplary description, and does not mean that the sensing area and the associated area of ​​the reference signal involved in this disclosure are all divided based on the cell; this will not be elaborated further below.

[0169] It should be noted that the embodiment shown in Figure 4 can be implemented independently or in combination with at least one other embodiment in this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope of the embodiment.

[0170] According to embodiments of this disclosure, based on the terminal's configured sensing area and / or the associated area of ​​the reference signal, it can be determined whether to continue sensing services when the terminal moves out of the first area. Accordingly, when cell handover or cell reselection occurs due to terminal movement or poor sensing reference signal quality, the terminal can determine whether to continue sensing services, which helps improve the performance of sensing technology and ensures the continuity of sensing services.

[0171] In some embodiments, the sensing area represents at least one of the following: when the terminal is located within the sensing area, sensing services are performed; the terminal senses a target located within the sensing area.

[0172] In some embodiments, the first region belongs to at least one of the following: a sensing region; an associated region of a reference signal; or a serving cell of the terminal.

[0173] In some embodiments, the sensing area is configured by the access network device and / or sensing network element; the associated area of ​​the reference signal is configured by the access network device and / or sensing network element.

[0174] In some embodiments, the sensing service is stopped when the terminal moves out of the first area.

[0175] In some embodiments, when the terminal moves out of the first area, the sensing service continues if the second area the terminal moves into is a sensing area. Alternatively, when the terminal moves out of the first area, the sensing service stops if the second area the terminal moves into is not a sensing area.

[0176] For example, after UE#1 moves out of cell#1 and into cell#2, since cell#2 belongs to the configured sensing area, UE#1 can continue to sense services in cell#2.

[0177] For example, after UE#1 moves out of cell#1 and into cell#2, since cell#2 does not belong to the configured sensing area and / or the associated area of ​​the reference signal, UE#1 stops sensing services in cell#2.

[0178] In some embodiments, the sensing configuration information is used in the second region. When the terminal moves out of the first region, the second region into which the terminal moves belongs to the sensing region is used to continue sensing services based on the sensing configuration information.

[0179] For example, the perception configuration information available to UE#1 is used in multiple areas, including cell#1 and cell#2. Therefore, after UE#1 moves out of cell#1 and into cell#2, UE#1 can continue to perceive services in cell#2 based on the existing perception configuration information, since cell#2 belongs to the configured perception area.

[0180] In some embodiments, the sensing configuration information is used for a first area. When the terminal moves out of the first area, it requests new sensing configuration information from the sensing network element or the access network device associated with the second area, based on the fact that the second area the terminal moves into belongs to the sensing area, and continues to sense services based on the requested sensing configuration information.

[0181] For example, the perception configuration information available to UE#1 is only used for one area, including cell#1. Therefore, after UE#1 moves out of cell#1 and into cell#2, since cell#2 belongs to the configured perception area, UE#1 can first request new perception configuration information for cell#2 from SF or gNB#2 associated with cell#2, and then continue to perceive services in cell#2 based on the requested perception configuration information.

[0182] In some embodiments, when the terminal moves out of the first area, the sensing service continues if the second area the terminal moves into belongs to the associated area of ​​the reference signal. And / or, when the terminal moves out of the first area, the sensing service stops if the second area the terminal moves into does not belong to the associated area of ​​the reference signal. And / or, when the terminal moves out of the first area, the sensing service continues if a reference signal is measured in the second area the terminal moves into. And / or, when the terminal moves out of the first area, the sensing service stops if a reference signal cannot be measured in the second area the terminal moves into. And / or, when the terminal moves out of the first area, the sensing service continues if the signal quality of the reference signal in the second area the terminal moves into is higher than a first threshold. And / or, when the terminal moves out of the first area, the sensing service stops if the signal quality of the reference signal in the second area the terminal moves into is lower than a second threshold.

[0183] In a further embodiment, the terminal sends first information to the sensing network element or the access network device associated with the second area. The first information is used to indicate the reason for determining whether to continue sensing services and / or the processing result of sensing services. The second area is the area that the terminal moves into after moving out of the first area.

[0184] Optionally, the sensing network element or the access network device associated with the second area receives the first information sent by the terminal.

[0185] In some embodiments, the reasons for determining whether to continue sensing services include at least one of the following: the terminal moves out of the first area; the terminal moves into the second area; a reference signal cannot be measured; no measurement results are available; the signal quality of the reference signal is lower than a second threshold; the terminal performs cell handover; the terminal performs cell reselection.

[0186] In some embodiments, the processing result of the sensing service includes one of the following: the terminal continues to sense the service; the terminal stops sensing the service.

[0187] For example, UE#1 can indicate to the SF or RAN side that the sensing service has ended, or that there is no valid sensing reference signal, or that the terminal moves out of cell#1, or that the terminal moves into cell#2, or that the sensing reference signal cannot be measured.

[0188] Optionally, the sensing network element or the access network device associated with the second area sends second information to the terminal, which is used to instruct the terminal to continue sensing services in the second area.

[0189] In a further embodiment, the terminal receives second information sent by a sensing network element or an access network device associated with the second area.

[0190] In some embodiments, the terminal reports third information to the sensing network element or access network device, the third information including the terminal's historical trajectory and / or the terminal's expected trajectory.

[0191] Optionally, the sensing network element or access network device receives third information reported by the terminal.

[0192] It should be noted that, for any parts not described in detail in the embodiments shown in Figure 4 above, please refer to the embodiments shown in Figure 3, which will not be repeated here.

[0193] Secondly, embodiments of this disclosure provide a method for processing sensing services. Figure 5 is a schematic flowchart illustrating another method for processing sensing services according to an embodiment of this disclosure. The method for processing sensing services shown in this embodiment can be executed by an access network device.

[0194] As shown in Figure 5, the processing method for sensing services may include the following steps:

[0195] In step S501, the terminal receives first information sent by the receiving terminal. The first information is used to indicate the reason for determining whether to continue the sensing service and / or the processing result of the sensing service. The processing result of the sensing service is determined by the terminal based on the sensing area configured for the terminal and / or the associated area of ​​the reference signal when the terminal moves out of the first area. The reference signal is used for sensing.

[0196] In some embodiments, the sensing mode used by the sensing service may include one of the following: terminal transmission and access network device reception; access network device transmission and terminal reception.

[0197] For example, gNB#1 associated with cell#1 can receive first information sent by UE#1. The first information can instruct the terminal to continue sensing services or stop sensing services. The first information can also indicate that the reason for determining whether to continue sensing services is that UE#1 has moved out of cell#1. The processing result of sensing services is determined by UE#1 based on the configured sensing area and / or the associated area of ​​the reference signal when UE#1 moves out of cell#1.

[0198] For example, after UE#1 moves out of cell#1 and into cell#2, gNB#2 associated with cell#2 can receive the first information sent by UE#1. The first information can instruct the terminal to continue sensing services or stop sensing services. The first information can also indicate that the reason for determining whether to continue sensing services is that UE#1 has moved out of cell#1. The processing result of sensing services is determined by UE#1 based on the configured sensing area and / or the associated area of ​​the reference signal when UE#1 moves out of cell#1.

[0199] It should be noted that the embodiment shown in Figure 5 can be implemented independently or in combination with at least one other embodiment in this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope.

[0200] Optionally, when the terminal moves out of the first area, it is determined whether to continue sensing services based on the terminal's configured sensing area and / or the associated area of ​​the reference signal, where the reference signal is used for sensing. Optionally, the terminal sends first information to the access network device.

[0201] According to embodiments of this disclosure, by receiving first information sent by the terminal, the access network device can learn the reason for determining whether to continue sensing services and / or the processing result of the sensing services. Accordingly, when cell handover or cell reselection occurs due to terminal movement or poor sensing reference signal quality, the terminal can determine whether to continue sensing services and indicate to the access network device the reason for determining whether to continue sensing services and / or the processing result of the sensing services. This is beneficial for improving the performance of sensing technology and ensuring the continuity of sensing services.

[0202] In some embodiments, the sensing area represents at least one of the following: when the terminal is located within the sensing area, sensing services are performed; the terminal senses a target located within the sensing area.

[0203] In some embodiments, the first region belongs to at least one of the following: a sensing region; an associated region of a reference signal; or a serving cell of the terminal.

[0204] In some embodiments, the access network device configures a sensing area for the terminal; and / or, the access network device configures an associated area for the reference signal for the terminal.

[0205] In some embodiments, the reasons for determining whether to continue sensing services include at least one of the following: the terminal moves out of a first area; the terminal moves into a second area, the second area being the area the terminal moves into after moving out of the first area; a reference signal cannot be measured; no measurement results are available; the signal quality of the reference signal is below a second threshold; the terminal performs cell handover; the terminal performs cell reselection.

[0206] In some embodiments, the processing result of the sensing service includes one of the following: the terminal continues to sense the service; the terminal stops sensing the service.

[0207] In some embodiments, the access network device sends a second message to the terminal, the second message being used to instruct the terminal to continue sensing services in a second area, the second area being the area the terminal moves into after moving out of the first area.

[0208] Optionally, the terminal receives second information sent by the access network device.

[0209] In some embodiments, when the terminal is in the RRC connected state, the result of the sensing service processing is that the terminal stops the sensing service, and the access network device selects another terminal to perform the sensing service.

[0210] For example, when UE#1 and gNB#1 associated with cell#1 are conducting sensing services, they are used to sense targets located within the sensing area cell#1. After UE#1 moves out of cell#1, it is no longer suitable to sense targets located within the sensing area cell#1. Therefore, gNB#1 can know that UE#1 has stopped the sensing service and select UE#2 located within the sensing area cell#1 to conduct the sensing service.

[0211] In some embodiments, when the terminal is in RRC idle state or RRC inactive state, the processing result of the sensing service is that the terminal stops the sensing service. If the reference signal sent by the terminal cannot be received, the access network device selects another terminal to perform the sensing service; and / or, if the signal quality of the reference signal is lower than the second threshold value, the access network device selects another terminal to perform the sensing service; and / or, if the measurement result sent by the terminal cannot be received, the access network device selects another terminal to perform the sensing service.

[0212] In a further embodiment, the access network device sends fourth information to the sensing network element, the fourth information being used to indicate the reason for determining whether to continue sensing services and / or the processing result of sensing services.

[0213] Optionally, the sensing network element can receive fourth information sent by the access network device.

[0214] In some embodiments, the terminal is in the RRC connected state; the fourth information is used to instruct the terminal to switch to the target cell, or the fourth information is used to instruct the sensing service to stop due to the terminal performing cell handover.

[0215] In some embodiments, the terminal is in an RRC idle state or an RRC inactive state; the fourth information is used to indicate error information of the sensing service, or the fourth information is used to indicate that the measurement results of the terminal cannot be obtained.

[0216] In some embodiments, when the terminal is in the RRC connected state, the serving cell of the terminal indicates to the target cell of the terminal that the terminal is performing a sensing service; and / or, the serving cell of the terminal requests a reference signal from the target cell of the terminal; and / or, the serving cell of the terminal requests sensing configuration information from the target cell of the terminal.

[0217] In some embodiments, the access network device sends sensing configuration information used by the terminal in the target cell to the terminal. Optionally, the terminal receives the sensing configuration information sent by the access network device.

[0218] In some embodiments, when the terminal is in the RRC connected state, the access network device provides the terminal's serving cell with reference signals available for the terminal to use; and / or, the access network device provides the terminal's serving cell with sensing configuration information available for the terminal to use.

[0219] Optionally, the terminal reports third information to the access network device, including the terminal's historical trajectory and / or the terminal's expected trajectory.

[0220] In some embodiments, the access network device receives third information reported by the terminal.

[0221] In some embodiments, the access network device sends sensing configuration information to the terminal, the sensing configuration information being used for one or more areas.

[0222] It should be noted that, for any parts not described in detail in the embodiments shown in Figure 5 above, please refer to the embodiments shown in Figure 3, which will not be repeated here.

The method for processing sensing services shown in this embodiment can be executed by sensing network elements.

[0224] As shown in Figure 6, the processing method for sensing services may include the following steps:

[0225] In step S601, the terminal receives first information sent by the receiving terminal. The first information is used to indicate the reason for determining whether to continue the sensing service and / or the processing result of the sensing service. The processing result of the sensing service is determined by the terminal based on the sensing area configured for the terminal and / or the associated area of ​​the reference signal when the terminal moves out of the first area. The reference signal is used for sensing.

[0226] In some embodiments, the sensing mode used by the sensing service may include one of the following: terminal transmission and access network device reception; access network device transmission and terminal reception.

[0227] For example, SF can receive first information sent by UE#1. The first information can instruct the terminal to continue sensing services or stop sensing services. The first information can also indicate that the reason for determining whether to continue sensing services is that UE#1 has moved out of cell#1. The processing result of sensing services is determined by UE#1 based on the configured sensing area and / or the associated area of ​​the reference signal when UE#1 moves out of cell#1.

[0228] It should be noted that the embodiment shown in Figure 6 can be implemented independently or in combination with at least one other embodiment in this disclosure. The specific choice can be made as needed, and this disclosure does not limit the scope.

Optionally, the terminal sends first information to the sensing network element.

[0230] According to embodiments of this disclosure, by receiving first information sent by the terminal, the sensing network element can learn the reason for determining whether to continue sensing services and / or the processing result of the sensing services. Accordingly, when cell handover or cell reselection occurs due to terminal movement or poor sensing reference signal quality, the terminal can determine whether to continue sensing services and indicate to the sensing network element the reason for determining whether to continue sensing services and / or the processing result of the sensing services.

[0237] In some embodiments, when the terminal is in the RRC connected state, the result of the sensing service processing is that the terminal stops the sensing service, and the sensing network element selects other terminals to perform the sensing service.

[0238] In some embodiments, when the terminal is in RRC idle or RRC inactive state, the processing result of the sensing service is that the terminal stops the sensing service. If the access network device associated with the first area cannot receive the reference signal sent by the terminal, the sensing network element selects another terminal to perform the sensing service; and / or, if the signal quality of the reference signal is lower than the second threshold value, the sensing network element selects another terminal to perform the sensing service; and / or, if the access network device associated with the first area cannot receive the measurement result sent by the terminal, the sensing network element selects another terminal to perform the sensing service.

[0239] Optionally, the access network device sends a fourth piece of information to the sensing network element. The fourth piece of information is used to indicate the reason for determining whether to continue sensing services and / or the processing result of sensing services.
