Furthermore, multiple systems may be combined (for example, a combination of LTE or LTE-A with 5G).

[0274] In some embodiments of the present disclosure, the above-mentioned communication system may support ISAC, which combines wireless communication and wireless perception and introduces close cooperation between the two, thereby improving spectrum efficiency and reducing network deployment costs.

[0275] In some embodiments, the terminal device and / or access network device can both implement wireless sensing, and therefore, the terminal device and / or access network device can also be referred to as a sensing device. In this communication system, there can be one or more terminal devices, and one or more access network devices.

[0276] In some embodiments, to implement an ISAC network architecture, a service-based interface can be used within the control plane. This ISAC network architecture can reuse existing core network functionality to implement sensing capabilities. Optionally, a sensing function (SF) can be added to core network devices. Based on the service-oriented interface, the SF can call interfaces of other functions and provide services. Optionally, the sensing function can be integrated with the LMF and / or other functions.

[0277] Optionally, SF can provide at least one of the following functions:

[0278] Receives sensing service requests from terminal devices or third-party applications;

[0279] Control the measurement process of access network equipment and terminal equipment, including authentication, discovery, capability negotiation and configuration, and perception mode selection;

[0280] Acquire perception data and perform calculations and processing to obtain perception results.

[0281] However, this ISAC system architecture does not consider the collaboration of sensing and computing tasks and can only be performed within core network devices, failing to leverage the capabilities of terminal devices and access network devices. Therefore, some embodiments of the present disclosure provide a mode determination method that can determine a sensing mode to leverage the capabilities of terminal devices and / or access network devices.

[0282] FIG2A is an interactive diagram illustrating a mode determination method according to an embodiment of the present disclosure. The method may be executed by the above-mentioned communication system. As shown in FIG2A , the method may include:

[0283] Step S2101: AF sends an eleventh message to NEF.

[0284] In some embodiments, the NEF may receive the eleventh message. For example, the NEF may receive the eleventh message sent by the AF.

[0289] In some embodiments, the name of the eleventh message is not limited, for example, it can be "sensing service request information" or the like.

[0290] Step S2102: NEF performs perception service authentication.

[0291] In some embodiments, the awareness service authentication is used to determine whether to request to perform the awareness service.

[0292] In some embodiments, the NEF may perform awareness service authentication on the awareness service request of the AF based on the eleventh message and authorization information. The authorization information may be stored in the NEF or the UDM.

[0293] In one implementation, if the perception device (e.g., terminal device and / or access network device) does not allow the perception service (e.g., a specific type of perception service) to obtain perception measurement data and / or perception calculation results, the NEF may reject the perception service request. For example, the NEF may send a twelfth message to the AF to reject the perception service request through the twelfth message.

[0294] Optionally, the perception measurement data may be data obtained by a perception device (such as a terminal device and / or an access network device) based on wireless perception, and the perception calculation result may be a result obtained by the perception device after data processing based on the perception measurement data. The data processing may include at least one of the following: data preprocessing, data calculation, and inputting the perception measurement data into an artificial intelligence AI model to obtain model output data.

[0295] In another implementation, if the authentication check passes, for example, the perception device allows the perception service to obtain perception measurement data and / or perception calculation results, the NEF can execute step S2103 and send a first message to the first network element, instructing the perception device to perform perception measurement and / or perception calculation.

[0296] Step S2103: The NEF sends a first message to the first network element.

[0297] In some embodiments, the first network element may receive the first message. For example, the first network element may receive the first message sent by the NEF.

[0313] In some embodiments, the third message may include first sensing capability information of the sensing device.

[0314] In some embodiments, the name of the third message is not limited, for example, it can be "perception capability request response message", "capability request response message", etc.

[0315] In some embodiments, the second network element may store the above-mentioned first perception capability information locally.

[0316] Optionally, the above-mentioned second message may include a perception device identifier, which may be a terminal identifier or an access network device identifier. Through the perception device identifier, the second network element may retrieve the first perception capability information corresponding to the perception device.

[0317] In some embodiments, the second network element may obtain first perception capability information of a perception device (terminal device or access network device) and store the information in the second network element.

[0318] For example, when registering on the network, the sensing device may send the device identification, registration area, first sensing capability information, etc. of the sensing device to the second network element. In this way, the second network element may obtain and store the first sensing capability information.

[0319] For another example, the sensing device may periodically send its first sensing capability information to the second network element, and the period may be a relatively long period, such as one hour, one day, or one week.

[0320] For another example, when the first sensing capability information of the sensing device changes, the sensing device may send the updated first sensing capability information to the second network element. The second network element may update the first sensing capability information corresponding to the sensing device. In this way, the accuracy of the first sensing capability information stored by the second network element can be ensured.

[0321] Step S2106: The first network element sends a fourth message to the perception device through the third network element and AMF.

[0322] In some embodiments, the sensing device may include a terminal device and / or an access network device.

[0335] Optionally, if the sensing device includes an access network device, the access network device may send the fifth message to the first network element through the third network element and the AMF. If the sensing device includes a terminal device, the terminal device may send the fifth message to the first network element through the third network element, the AMF, and the access network device.

[0336] In some embodiments, the fifth message may include the above-mentioned second sensing capability information of the sensing device.

[0337] In some embodiments, the name of the fifth message is not limited, for example, it can be "perception capability reporting message", "perception capability information", etc.

[0338] In some embodiments, the first network element may obtain the second sensing capability information of the sensing device (terminal device or access network device). Optionally, the first network element may store the obtained second sensing capability information in the first network element.

[0339] In some embodiments, the sensing device may send the fifth message to the first network element in response to receiving the fourth message.

[0340] In other embodiments, the sensing device may periodically send the fifth message to the first network element in response to receiving the fourth message. For example, the sensing device may send the fifth message every N seconds or N minutes, where N may be a positive integer greater than or equal to 1.

[0341] In some other embodiments, the perception device may send the fifth message to the first network element in response to receiving the fourth message, and send updated second perception capability information to the first network element within a preset time thereafter when the second perception capability information changes.

[0344] In some embodiments of the present disclosure, there are various ways for a first network element to obtain the sensing capability information of a sensing device (terminal device and / or access network device). In one implementation, the first network element may obtain the sensing capability information of the sensing device through at least one of steps S2104 to S2107. In another implementation, the first network element may store the sensing capability information of the sensing device, and steps S2104 to S2107 may be omitted.

[0345] In some embodiments, the sensory capability information may include first sensory capability information and / or second sensory capability information, wherein:

[0346] The first perception capability information may be capability information corresponding to the perception device stored in the second network element, such as static capability information of the perception device.

[0347] The second perception capability information may be capability information reported by the perception device to the first network element through the AMF and the third network element, for example, dynamic capability information of the perception device.
