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.

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.

[0042] 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.

[0051] The embodiment of the present invention provides a method for processing a perception service, referring to Figure 1 , the following is a detailed description through specific steps.

[0052] The perception service processing method provided by the present invention can be applied in the fifth generation (5Generation, 5G) communication system, can also be applied in the 4G communication system, and can also be applied in the subsequent updated communication system (such as 6G, 7G, etc.). The perception service processing method provided by the present invention can also be applied to other network architectures, including terrestrial communication network architecture, non-terrestrial communication network architecture, relay network architecture, dual link architecture, vehicle-to-everything communication architecture, and other architectures.

[0053] In a specific implementation, the following perception service processing method may be executed by a chip with data processing function in a source access network device, or by a chip module with data processing function in a source access network device, or by the source access network device.

[0054] The following is an explanation using the method for source access network equipment to perform perception service processing as an example.

[0055] Step 101, determine to switch the terminal device to the target access network device and send the perception service information.

[0056] 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 a cell measurement operation based on the received measurement information. The source access network device may determine whether to perform a cell switching operation on the terminal device based on the measurement result of the terminal device.

[0057] Specifically, the specific process by which the source access network device determines 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.

[0058] 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, which 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.

[0059] In a specific implementation, the source access network device may send the perceived service information to the target access network device through the communication interface between the access network devices. Alternatively, the source access network device may also send the perceived service information to the core network element through 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.

[0060] 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.

[0061] 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 identification, or a communication layer QoS flow identification, or a PDU session identification.

[0062] 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.

[0063] 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 elaborated here.

[0064] In practical applications, it can be known that by classifying the perception modes according to the devices that send and receive the perception signals, the following perception modes can be obtained: Perception mode one, the network device spontaneously sends and receives the perception signal; Perception mode two, collaborative perception between network devices, such as the first network device sends the perception signal, and the second network device receives the perception signal; Perception mode three, the network device sends the perception signal, and the terminal device receives the perception signal; Perception mode four, the terminal device sends the perception signal, and the network device receives the perception signal; Perception mode five, the terminal device spontaneously sends and receives the perception signal; Perception mode six, collaborative perception between terminal devices, such as the first terminal device sends the perception signal, and the second terminal device receives the perception signal.

[0065] 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.

[0066] In a specific implementation, the information of the perceived target may include the information of the perceived object and / or the information of the perceived area. The information of the perceived object may include the position of the perceived object, the moving speed of the perceived object, the moving direction of the perceived object, etc. The perceived objects may include vehicles, pedestrians, obstacles, etc. The information of the perceived area may include the geographical location of the perceived area, the distribution of obstacles in the perceived area, etc. The perceived area may be a predetermined area. Different areas may be represented by different area identifiers.

[0067] 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.

[0068] In some embodiments, the perception data may be represented by perception measurement data, perception measurement results, etc.

[0069] In a specific implementation, the sensed 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 sensed data or obtain the sensed data. In this scenario, the reporting address information of the sensed data may be the address information of the data collection server, such as the IP address information of the data collection server.

[0070] The data collection server may be a local server or a cloud server. If the data collection server is a local server, the data server may be set in the source network device or may be an independent data server. In the reporting address information of the perception data, it may also be indicated whether the data collection server is a local server.

[0071] 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.

[0072] Specifically, the measurement result may be raw data obtained by the perception measurement operation, such as the measured signal quality, signal-to-noise ratio, etc. The perception result may be a perception measurement result obtained after processing the measurement result, such as the moving speed of the perceived target, the position of the perceived target, etc. The intermediate processing result may refer to a measurement result that has been partially processed but the perception result has not yet been obtained.

[0073] In some embodiments, the reason for the existence of intermediate processing results may be that only the original data obtained by the measurement operation needs to be combined with other data to obtain the perception result. Or, when the terminal device performs the perception service, due to insufficient computing power of the terminal device, only the original data is preliminarily processed. It is understandable that the reason for the existence of intermediate processing results may be other reasons, which will not be elaborated here.

[0074] 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.

[0075] Step 102, obtaining first information.

[0076] In a specific implementation, the first information may be used to indicate whether the target cell supports the target perception service.

[0077] 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 a first message to the source access network device, and the first message 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 a first message to the source access network device, and the first message 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.

[0078] In a specific implementation, the source access network device may send the second information.

[0079] 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.

[0080] 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.

[0081] 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, and the third information is used to indicate whether to request the perception data corresponding to the target perception service.

[0082] 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 the perception data corresponding to the target perception service is requested; 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 the perception data corresponding to the target perception service is not needed.

[0083] 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.

[0084] 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, or an intermediate processing result, or a combination of the above three types.

[0085] The target access network device receives the second information, determines that the source access network device has the perception data corresponding to the target perception service and the type of the perception data, and determines whether the perception data is needed. The target access network device sends the third information, indicating that the perception data corresponding to the target perception service and the type of the perception data are needed. The source access network device receives the third information and sends the corresponding type of perception data to the target access network device.

[0086] For example, the source access network device is base station 1, and the target access network device is base station 2. There is perception data corresponding to perception service A in base station 1, and the types of perception data include measurement results and perception results. Base station 1 sends second information to base station 2, and the second information indicates that there is perception data corresponding to perception service A in base station 1, and the types of perception data include measurement results and perception results. Base station 2 determines that perception data of the type of perception results is needed, and then sends third information to base station 1. Base station 1 receives the third information and sends perception data of the type of perception results to base station 2.

[0087] It can be seen that the target access network device obtains the second information and can learn that the source access network device has the perception data corresponding to the target perception service, and then determines whether to request the perception data corresponding to the target perception service according to its own needs. In this way, the continuity of data transmission during the switching process of the terminal device can be achieved, and the performance of the perception service in the mobility scenario can be guaranteed.

[0088] In a specific implementation, the perceived service information may reuse messages used for communication between existing access network devices, or may reuse messages used for communication between existing access network devices and core network elements.

[0089] Specifically, the message for transmitting the perceived service information can be a handover request (HANDOVERREQUEST) message between access network devices, or can be a handover requirement (HANDOVERREQUIRED) message used for communication between the access network device and the core network element, or can be a handover request (HANDOVERREQUEST) message between the access network device and the core network element.

[0090] It can be understood that the message for transmitting the perception service information may also be a newly added message, which is different from the above-mentioned existing message.

[0091] In a specific implementation, the message for transmitting the first information may reuse the message used for communication between existing access network devices, or may reuse the message used for communication between existing access network devices and core network elements.

[0092] Specifically, the message for transmitting the first information may be a handover request confirmation (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 confirmation (HANDOVER REQUEST ACKNOWLEDGE) message or a handover failure (HANDOVER FAILURE) message between an access network device and a core network element.

[0093] It can be understood that the message for transmitting the first information may also be a newly added message, which is different from the above-mentioned existing message.

[0094] 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.

[0095] 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.

[0096] Reference Figure 2 , another perception service processing method in an embodiment of the present invention is given, which is described in detail through specific steps below.

[0097] In a specific implementation, the following perception service processing method may 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.

[0098] The following is an explanation using the target access network device executing the perception service processing method as an example.

[0099] Step 201: Acquire perception service information.

[0100] In a specific implementation, the source access network device may send the perceived service information to the target access network device through the communication interface between the access network devices. Alternatively, the source access network device may also send the perceived service information to the core network element through 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.

[0101] Step 202, sending the first information.

[0102] 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 a first message to the source access network device, and the first message 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 a first message to the source access network device, and the first message 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.

[0103] In a specific implementation, the source access network device may send the second information.

[0104] 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.

[0105] 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.
