[0042] In the existing technology, only some access network devices may support perception services. Different access network devices may support different types of perception services. In some scenarios, terminal device 1 is performing perception service A. When the source access network device determines to switch terminal device 1 to the target cell corresponding to the target access network device, the source access network device does not know whether the target cell supports perception service A. If the target cell does not support perception service A, switching terminal device 1 to the target cell will cause perception service A to be interrupted.

[0043] In an embodiment of the present invention, the source access network device determines to switch the terminal device to the target access network device and sends the perception service information. The source access network device obtains the first information, thereby knowing whether the target cell supports the target perception service and further determining whether to switch the terminal device to the target cell.

[0044] Furthermore, if the target cell does not support the target perception service, the source access network device may stop switching the terminal device to the target cell and reselect other cells that support the target perception service, thereby improving the continuity of the perception service.

[0048] 2. Access network equipment. In the embodiments of the present invention, the access network equipment is a device that provides wireless communication functions for terminal devices, and may also be referred to as a radio access network (RAN) device or an access network element.

Devices providing base station functions in NR include next-generation node base stations (gNBs) and evolved Node Bs (ng-eNBs). Communication between gNBs and terminal devices utilizes NR technology, while communication between ng-eNBs and terminal devices utilizes Evolved Universal Terrestrial Radio Access (E-UTRA) technology.

Alternatively, these functions can be implemented by existing core network elements.

[0051] 4. Uplink communication. In the embodiments of the present invention, uplink communication, also known as uplink transmission, refers to unidirectional communication from a terminal device to an access network device.

The communication link used for downlink communication is the uplink. Data transmitted on the downlink is downlink data. The transmission direction of downlink data is the downlink direction.

[0053] An embodiment of the present invention provides a method for processing a perception service, which is described in detail below through specific steps with reference to FIG1 .

[0054] The perception service processing method provided by the present invention can be applied in fifth-generation (5G) communication systems, 4G communication systems, and subsequent updated communication systems (such as 6G and 7G). The perception service processing method provided by the present invention can also be applied to other network architectures, including terrestrial communication network architectures, non-terrestrial communication network architectures, relay network architectures, dual-link architectures, and vehicle-to-everything communication architectures.

[0055] In a specific implementation, the following perception service processing method can be executed by a chip with data processing function in the source access network device, or by a chip module with data processing function in the source access network device, or by the source access network device.

[0056] The following describes a method for processing a sensing service by a source access network device as an example.

[0057] Step 101: Determine to switch the terminal device to the target access network device and send the perception service information.

[0058] In a specific implementation, the source access network device may configure measurement information for the terminal device and send the measurement information to the terminal device. The terminal device performs cell measurement operations based on the received measurement information. The source access network device may determine whether to perform a cell handover operation on the terminal device based on the measurement results of the terminal device.

[0059] Specifically, the specific process of the source access network device determining whether to perform a cell switching operation on the terminal device can refer to the existing protocol, and only the above brief description is given here.

[0060] In an embodiment of the present invention, the source access network device determines to switch the terminal device to the target access network device and can send perception service information. The perception service information can be used to indicate the target perception service, or to indicate parameters associated with the target perception service, or to indicate the target perception service and its associated parameters.

[0061] In a specific implementation, the source access network device can send the perceived service information to the target access network device via the communication interface between the access network devices. Alternatively, the source access network device can send the perceived service information to the core network element via the communication interface between the source access network device and the core network element, and the core network element then sends the perceived service information to the target access network device.

[0062] In an embodiment of the present invention, parameters associated with perception service information may include one or more of the following: identification information of the target perception service, performance parameters of the target perception service, perception mode corresponding to the target perception service, information of the perceived target, reporting address information of the perception data, perception configuration information, and type of perception data.

[0063] In a specific implementation, the identification information of the target-aware service can be used to indicate the target-aware service. Specifically, the identification information of the target-aware service can be an application layer service identifier, a communication layer QoS flow identifier, or a PDU session identifier.

[0064] In a specific implementation, the performance parameters of the target perception service may include any one or more of perception distance, distance resolution, perception speed, speed resolution, perception angle, angle resolution, perception delay, etc.

[0065] Specifically, the content and specific values ​​of the performance parameters of the target perception service can be set according to the actual scenario and will not be described in detail here.

[0066] In actual applications, it can be seen that by classifying the perception modes according to the devices that send and receive perception signals, the following perception modes can be obtained: Perception mode one, network devices spontaneously send and receive perception signals; Perception mode two, collaborative perception between network devices, such as the first network device sends a perception signal and the second network device receives the perception signal; Perception mode three, the network device sends a perception signal and the terminal device receives the perception signal; Perception mode four, the terminal device sends a perception signal and the network device receives the perception signal; Perception mode five, the terminal device spontaneously sends and receives perception signals; Perception mode six, collaborative perception between terminal devices, such as the first terminal device sends a perception signal and the second terminal device receives the perception signal.

[0067] In an embodiment of the present invention, the perception mode corresponding to the target perception service may include the above-mentioned perception mode three, perception mode four or perception mode six.

[0068] In specific implementations, information about the perceived target may include information about the perceived object and / or information about the perceived area. Information about the perceived object may include its location, speed, and direction. Perceived objects may include vehicles, pedestrians, and obstacles. Information about the perceived area may include its geographic location and the distribution of obstacles within the area. The perceived area may be a predetermined region. Different regions may be represented by different area identifiers.

[0069] In a specific implementation, the perception data can be reported to the source network device. In this scenario, the reporting address information of the perception data can be the address information of the source network device; or, the address information of the source network device is represented by the identifier of the source network device, then the reporting address information of the perception data can be the identifier of the source network device.

[0070] In some embodiments, the perception data may be represented by perception measurement data, perception measurement results, etc.

[0071] In a specific implementation, the perception data may also be reported to a data collection server, and the source network device may communicate with the data collection server to report the perception data or obtain the perception data. In this scenario, the reporting address information of the perception data may be the address information of the data collection server, such as the IP address information of the data collection server.

[0072] The data collection server can be a local server or a cloud server. If the data collection server is a local server, the data server can be set up in the source network device or as a standalone data server. The reporting address information of the perception data can also indicate whether the data collection server is a local server.

[0073] In a specific implementation, the perception data is divided into the following three types according to the content contained in the perception data: measurement results, perception results, and intermediate processing results corresponding to the measurement results.

[0074] Specifically, a measurement result may be raw data obtained from a sensory measurement operation, such as the measured signal quality or signal-to-noise ratio. A sensory result may be a sensory measurement result obtained by processing the measurement result, such as the moving speed or position of the sensed target. An intermediate processing result may refer to a measurement result that has been partially processed but has not yet obtained a sensory result.

[0075] In some embodiments, the existence of intermediate processing results may be due to the need to combine the raw data obtained from the measurement operation with other data to obtain the perception result. Alternatively, when performing the perception service, the terminal device may only perform preliminary processing on the raw data due to insufficient computing power. It is understood that the existence of intermediate processing results may also be due to other reasons, which are not detailed here.

[0076] In a specific implementation, the sensing configuration information may include one or more of uplink sensing signal configuration information, downlink sensing signal configuration information, a sensed object, a sensed area, and the like.

[0077] Step 102: Obtain first information.

[0078] In a specific implementation, the first information may be used to indicate whether the target cell supports the target perception service.

[0079] In a specific implementation, if the target access network device determines that the target cell supports the target perception service, the target access network device sends first information to the source access network device, where the first information is used to indicate that the target cell supports the target perception service. If the target access network device determines that the target cell does not support the target perception service, the target network may also send first information to the source access network device, where the first information is used to indicate that the target cell does not support the target perception service. Supporting the target perception service means that the target cell recognizes or accepts the target perception service of the terminal device.

[0080] In a specific implementation, the source access network device may send the second information.

[0081] In some embodiments, the source access network device receives the first information and determines that the target cell supports the target perception service. The source access network device can send second information to the target access network device, and the second information can be used to indicate the existence of perception data corresponding to the target perception service.

[0082] In other embodiments, the perception service information sent by the source access network device includes the second information. That is, the source access network device indicates the target perception service and / or parameters associated with the target perception service to the target access network device, and indicates that the source access network device has perception data corresponding to the target perception service.

[0083] The target access network device receives the second information and determines whether the perception data corresponding to the target perception service is needed. The target access network device sends third information to the source access network device, the third information being used to indicate whether to request the perception data corresponding to the target perception service.

[0084] Specifically, if the target access network device needs to request the perception data corresponding to the target perception service, it can indicate in the third information that it requests the perception data corresponding to the target perception service; conversely, if the target access network device does not need the perception data corresponding to the target perception service, it can indicate in the third information that it does not need the perception data corresponding to the target perception service.

[0085] The source access network device receives the third information, and if it is determined that the target access network device needs the perception data corresponding to the target perception service, the source access network device may send the perception data corresponding to the target perception service to the target access network device.

[0086] In some embodiments, the second information may also be used to indicate the type of the perception data. That is, the source access network device may also indicate to the target access network device whether the type of the perception data is a measurement result, a perception result, an intermediate processing result, or a combination of the above three types.

[0087] The target access network device receives the second information, determines that the source access network device has perception data corresponding to the target perception service and the type of the perception data, and determines whether the perception data is required. The target access network device sends third information indicating that the perception data corresponding to the target perception service and the type of the perception data are required. The source access network device receives the third information and sends the corresponding type of perception data to the target access network device.

[0088] For example, the source access network device is base station 1, and the target access network device is base station 2. Base station 1 contains perception data corresponding to perception service A, where the types of perception data include measurement results and perception results. Base station 1 sends second information to base station 2, indicating that base station 1 contains perception data corresponding to perception service A, where the types of perception data include measurement results and perception results. Base station 2 determines that perception data of the perception result type is required, and then sends third information to base station 1. Base station 1 receives the third information and sends the perception data of the perception result type to base station 2.

[0089] As can be seen, the target access network device, upon obtaining the second information, can learn that the source access network device has the perception data corresponding to the target perception service, and can then determine whether to request the corresponding perception data based on its own needs. This ensures data transmission continuity during terminal device handover and ensures the performance of the perception service in mobility scenarios.

[0090] In a specific implementation, the perception service information may reuse messages used for communication between existing access network devices, or reuse messages used for communication between existing access network devices and core network elements.

[0091] Specifically, the message for transmitting perception service information can be a handover request (HANDOVER REQUEST) message between access network devices, or a handover requirement (HANDOVER REQUIRED) message used for communication between access network devices and core network elements, or a handover request (HANDOVER REQUEST) message between access network devices and core network elements.

[0092] It is understandable that the message for transmitting the awareness service information may also be a newly added message, which is different from the above-mentioned existing message.

[0093] In a specific implementation, the message for transmitting the first information may reuse the message used for communication between existing access network devices, or reuse the message used for communication between existing access network devices and core network elements.

[0094] Specifically, the message transmitting the first information may be a Handover Request Acknowledgement (HANDOVER REQUEST ACKNOWLEDGE) message or a Handover Preparation Failure (HANDOVER PREPARATION FAILURE) message between access network devices. The first information may also be a Handover Request Acknowledgement (HANDOVER REQUEST ACKNOWLEDGE) message or a Handover Failure (HANDOVER FAILURE) message between an access network device and a core network element.

[0095] It is understandable that the message for transmitting the first information may also be a newly added message, different from the above-mentioned existing message.

[0096] In summary, in the above embodiment, the source access network device determines to switch the terminal device to the target access network device and sends the perception service information. The source access network device obtains the first information, thereby knowing whether the target cell supports the target perception service, and then determines whether to switch the terminal device to the target cell.

[0097] In an embodiment of the present invention, if the source access network device determines based on the first information that the target cell does not support the target perception service, the source access network device can stop switching the terminal device to the target cell, and re-select the target cell for switching, and try to select a cell that supports the target perception service, thereby improving the continuity of the perception service.

[0098] 2 , another method for processing a perception service in an embodiment of the present invention is provided, which is described in detail below through specific steps.

[0099] In a specific implementation, the following perception service processing method can be executed by a chip with data processing function in the target access network device, or by a chip module with data processing function in the target access network device, or by the target access network device.

[0100] The following describes the method for processing a target access network device performing a perception service as an example.

[0101] Step 201: Acquire perception service information.

[0102] In a specific implementation, the source access network device can send the perceived service information to the target access network device via the communication interface between the access network devices. Alternatively, the source access network device can send the perceived service information to the core network element via the communication interface between the source access network device and the core network element, and the core network element then sends the perceived service information to the target access network device.

[0103] Step 202: Send the first information.

[0104] In a specific implementation, if the target access network device determines that the target cell supports the target perception service, the target access network device sends first information to the source access network device, where the first information is used to indicate that the target cell supports the target perception service. If the target access network device determines that the target cell does not support the target perception service, the target network may also send first information to the source access network device, where the first information is used to indicate that the target cell does not support the target perception service. Supporting the target perception service means that the target cell recognizes or accepts the target perception service of the terminal device.

[0105] In a specific implementation, the source access network device may send the second information.

[0106] In some embodiments, the source access network device receives the first information and determines that the target cell supports the target perception service. The source access network device can send second information to the target access network device, and the second information can be used to indicate the existence of perception data corresponding to the target perception service.

[0107] In other embodiments, the perception service information sent by the source access network device includes the second information. That is, the source access network device indicates the target perception service and / or parameters associated with the target perception service to the target access network device, and indicates that the source access network device has perception data corresponding to the target perception service.

[0108] The target access network device receives the second information and determines whether the perception data corresponding to the target perception service is needed. The target access network device sends third information to the source access network device, the third information being used to indicate whether to request the perception data corresponding to the target perception service.
