[0171] In recent years, the sixth-generation mobile communication system (6G) has become a global research hotspot. A variety of new vertical application scenarios, represented by smart cities, smart transportation, intelligent manufacturing, and smart homes, will emerge in the 6G era. These require communication equipment and terminals to have the ability to perceive the physical world and mirror the digital world. The deep integration of communication systems with multiple systems such as perception and artificial intelligence has become a new trend in technological development.

[0172] The development of communication and perception has always been independent and relatively parallel. Therefore, in 6G interawareness convergence, it is necessary to consider both the differences and commonalities between communication and perception, and create minimalist, efficient, and easy-to-deploy 6G interawareness convergence equipment and networking models. 6G networks will provide users with a more personalized service experience, and network status and resource supply should be aligned with user needs. Through the collaboration and sharing of interawareness computing software and hardware resources, the various network elements within this network will achieve a deep integration and mutually beneficial enhancement of multi-dimensional perception, collaborative communication, and intelligent computing capabilities, thereby enabling the network to intelligently interact and process new types of information flows and achieve wide-area intelligent collaboration. As shown in Figure 2, a schematic diagram of the 6G core network structure is shown. The network structure includes the terminal equipment UE, the access network (R)AN and the SMF network element and UPF network element in the core network, which also includes the input network element (input), the output network element (output) and the storage network element (storage); the network structure also includes the AMF network element, the unified data management (UDM), the authentication server function (AUSF), the user data register (UDR), the network storage function (NRF), the policy control function (PCF), the application function (AF), the gateway (GW), the network element function (NEF) and the data network (DN).

[0173] FIG3A is a flow chart of a method for modifying a session of a perception service according to an embodiment of the present disclosure. As shown in FIG3A , the embodiment of the present disclosure relates to a method for modifying a session of a perception service, the method comprising:

[0174] Step S3101: The terminal device sends a fourth request to the fifth network element.

[0175] In some implementations, the fifth network element may be an AMF network element.

[0176] In some implementations, the terminal device may send the fourth request to an access network device, such as a (R)AN, and send the first request to the AMF through the (R)AN. In other words, the terminal device transparently transmits the fourth message to the AMF via the (R)AN.

[0177] In some implementations, the terminal device may send a fourth request to the AMF through an existing message. For example, the existing message may be a non-access stratum (NAS) message, that is, the terminal device may send a fourth request to the AMF through a non-access stratum (NAS) message.

[0178] In some implementations, the terminal device may send a fourth request to the AMF via a constructed new message.

[0179] In some implementations, the fourth request may be indicated by reusing a spare information field of an existing message.

[0180] In some implementations, the fourth request may be used to request modification capabilities of a perception session (SC Session) of the terminal device.

[0181] In some implementations, the fourth request may be used to indicate the modification capability of the terminal device regarding the awareness session.

[0182] In some implementations, the fourth request may be used to request an update or adjustment to the awareness session of the terminal device.

[0183] In some implementations, the fourth request may be used to request modification of the awareness session of the terminal device.

[0184] In some implementations, the fourth request may include, but is not limited to, one or more of a perception service session identifier (SC Session ID) and a perception session modification request. For example, the perception session modification request may include, but is not limited to, adjusting perception accuracy, updating a perception period, adjusting perception data volume, switching a perception service, and the like.

[0185] In some embodiments, the name of the fourth request is not limited, and it can be, for example, "perception session modification request", "perception session modification indication information", "perception session update request", "perception session adjustment request", etc.

[0186] In some implementations, the sensing service may include but is not limited to speed measurement, temperature measurement, distance measurement, or services that require the collection of sensing data by sensors, cameras, etc. The sensing session modification request for the sensing service is to modify the set features of the sensing service.

[0187] For example, in the perception service of speed measurement, the terminal device pre-modifies the speed measurement accuracy. For example, if there is a higher accuracy requirement, the terminal device can transparently transmit the fourth request (perception session modification request) to AFM through (R)AN to request the core network device to modify the accuracy of the perception service of speed measurement.

[0188] Step S3102: The fifth network element sends a third request for sensing the service to the third network element.

[0189] In some implementations, the third network element may be an SMF network element.

[0190] In some implementations, the AMF network element may send a third request to the SMF through an existing message. Optionally, the update session context request sent by the AMF network element to the SMF network element includes the third request. Optionally, the third request may reuse the idle information field of the existing message for indication. Optionally, after receiving the fourth request sent by the terminal device, the AMF may obtain the session identifier of the perception service and the session modification request information of the perception service, and further, based on the session identifier of the perception service and the modification request of the perception service, send a third request to the SMF.

[0191] In some implementations, the third request includes at least one of a session identifier of the awareness service and session modification request information of the awareness service.

[0192] In some implementations, the third request is used to request the SMF network element to perform a context update of the perception session.

[0193] In some implementations, the third request is used to instruct the SMF network element to perform a context update of the awareness session.

[0194] In some embodiments, the name of the third information is not limited, and it can be, for example, "session context update request", "session context update indication", "session context update request message", "session context modification message", etc.

[0195] Step S3103: The third network element sends a first request for sensing the service to the first network element.

[0196] In some implementations, the first request includes at least session modification information of the awareness service.

[0197] In some implementations, the first request is used to request the first network element to perform session modification for the perception service.

[0198] In some implementations, the first request is used to instruct the first network element to modify a session of the awareness service.

[0199] In some embodiments, the name of the first request is not limited, and may be, for example, "session modification information", "session modification indication", "session modification request update message", "session modification message", etc.

[0200] In some implementations, the first network element may be an input network element, configured to analyze an update requirement of the perception service according to the first request.

[0201] In some implementations, the first request includes at least a request to modify a sensing service session. For example, the request to modify a sensing session may include, but is not limited to, adjusting sensing accuracy, updating sensing period, adjusting sensing data volume, switching sensing services, and the like.

[0202] In some implementations, the SMF network element may send the first request to the first network element via an existing message.

[0203] In some implementations, the SMF network element may send the first request to the first network element via a constructed new message.

[0204] In step S3104, the first network element interacts with the second network element to obtain perception information of the perception service.

[0205] The perception information of the perception service includes the node identifier of the updated first perception node of the perception service and the node configuration information of the first perception node.

[0206] In some implementations, the second network element may be a storage network element, configured to store node configuration information of the sensing node.

[0207] In some implementations, the first network element sends the second request to the second network element. Alternatively, the first network element may send the second request to the second network element via an existing message. Alternatively, the first network element may send the second request to the second network element via a constructed new message.

[0208] In some implementations, the second request includes, but is not limited to, an SC Session modification request.

[0209] In some implementations, the second request is used to request node configuration information of a candidate sensing node in the sensing service.

[0210] In some implementations, the second request is used to instruct acquisition of node configuration information of a candidate sensing node in the sensing service.

[0211] In some embodiments, the name of the second request is not limited, and may be, for example, "node configuration information acquisition request", "node configuration information request message", "obtain node configuration message", etc.

[0212] In some implementations, after receiving the second request, the second network element may obtain one or more candidate sensing nodes and node configuration information of the candidate sensing nodes based on the SC Session modification request in the second request. Optionally, all sensing nodes and node configuration information of all sensing nodes may be obtained; alternatively, some sensing nodes and node configuration information of the sensing nodes that meet the modification request may be obtained.

[0213] In some implementations, the node configuration information may include, but is not limited to, accuracy information, storage information, or traffic criticality information of the sensing node.

[0214] In some implementations, the first network element receives candidate sensing nodes and node configuration information of the candidate sensing nodes from the second network element, determines a first sensing node from the candidate sensing nodes based on the updated service requirement of the sensing service in the first request, and determines sensing information using the node identifier of the first sensing node and the node configuration information of the first sensing node. In other words, based on the updated service requirement, one or more first sensing nodes that meet the service requirement are selected.

[0215] In some implementations, the perception information may include, but is not limited to, a node identifier of the first perception node and node configuration information of the first perception node.

[0216] In some implementations, the first sensing node is at least one of the following nodes: a sensing node on the terminal device side, a sensing node on the network device side, and a third-party sensing node.

[0217] Optionally, the terminal device may be a user equipment UE, the network device may be the next generation NodeB (gNB), and the third-party perception node may be various sensors or image capture devices such as cameras and webcams.

[0218] Step S3105: The first network element sends perception information to the fourth network element.

[0219] In some implementations, the fourth network element may be a UPF network element.

[0220] Step S3106: The fourth network element sends node configuration information to the first perception node after the service is updated according to the perception information.

[0221] After receiving the perception information of the first network element, the UFP network element sends node configuration information to the first perception node according to the perception information.

[0222] Step S3107: The fourth network element sends the first information to the third network element.

[0223] In some implementations, the first information includes at least a session modification result of the awareness service.

[0224] In some implementations, the first information further includes a session identifier of the awareness service, session modification request information of the awareness service, and awareness information of the awareness service.

[0225] Step S3108: The third network element sends the first information to the fifth network element.

[0226] In some implementations, the AMF network element receives first information, which is used to instruct the AMF network element to update the wireless resource configuration according to the perception session modification result in the first information.

[0227] In some implementations, the AMF network element sends the first information to the (Radio) Access Network (R)AN), and the (R)AN updates the wireless resource configuration based on the perception session modification result in the first information.

[0228] Step S3109: The terminal device and the wireless access network device confirm the modification of the perception service.

[0229] After receiving the perception session modification result, the radio access network device (R)AN can confirm the modification result of the perception service with the user equipment UE. Optionally, the user equipment UE receives the perception session modification result from the radio access network device (R)AN and determines that the perception session modification of the perception service is completed.

[0230] Step S3110: The wireless access network device sends the first information to the fifth network element.

[0231] The AMF network element receives the first information and determines that the perception session modification of the perception service is completed.

[0232] Step S3111: The fifth network element sends first information to the third network element.

As shown in Figures 7A and 7B, an embodiment of the present disclosure relates to a method for modifying a session of a perception service, the method comprising:

[0318] Step S7101: The terminal device sends a perception session modification request to the AMF network element.

[0319] The UE pre-modifies the ongoing perception service. The user equipment UE sends a non-access NAS message to the access and mobility management function AMF via the radio access network (R)AN to initiate a perception session modification request. The message includes the SC Session ID and the SC Session modification request.

[0320] Step S7102, the AMF network element sends a request to update the session context to the SMF network element.

[0321] The AMF sends a session context update request to the SMF based on the SC Session ID. The request message contains the SC Session ID and the SC Session modification request.

[0322] Step S7103: The SMF network element sends an SC Session modification request to the Input network element.

[0323] The SMF sends an SC Session modification request to the Input network element, and the Input network element analyzes the service update requirements based on the request message.

[0324] In step S7104, the Input network element interacts with the Storage network element to obtain perception information.

[0325] The Input interacts with the Storage network element and selects and updates the perception node based on the SC Session modification request information.

[0326] Step S7105: The Input network element sends perception information to the UPF network element.

[0327] Input sends the perception information to UPF, including the updated perception node information and perception data input request.

[0328] Step S7106, UPF sends node configuration information.

[0329] After receiving the request, the UPF sends a new sensing data input request to the corresponding sensing node, which may include the UE, gNB, and third-party sensing nodes.

[0330] Step S7107, the UPF network element sends the session modification result to the SMF network element.

[0331] UPF returns the perception session modification result to SMF. The message includes SC Session ID, SC Session modification request, and perception node update result.

[0332] Step S7108, the SMF network element sends session modification information to the AMF network element.

[0333] The SMF returns the perception session modification result to the AMF. The AMF sends the perception session modification result to the (R)AN. The (R)AN updates the radio resource configuration based on the perception session modification result.

[0334] Step S7109: The terminal device and the wireless access network device confirm the modification of the perception service.

[0335] (R)AN and UE confirm that the session modification is complete.

[0336] Step S7110: The wireless access network device sends the session modification information to the AMF network element.

[0337] (R)AN sends the session modification confirmation message to AMF.

[0338] Step S7111, the AMF network element sends session modification information to the SMF network element.
