In this case, the interfaces between or within the access network devices involved in the embodiments of the present disclosure can be transformed into internal interfaces of the Open RAN, and the processes and information interactions between these internal interfaces can be implemented through software or programs.

[0106] In some embodiments, the access network device can be composed of a centralized unit (CU) and a distributed unit (DU), where the CU can also be called a control unit.

[0114] Step 101: A first node sends capability update information of the first node to a core network device.

[0115] In some embodiments, the first node may be a perception node and / or a computing power node configured to perform perception service tasks in a perception service session with the UE. When the first node is a perception node, the capability update information may correspond to perception capability update information. When the first node is a computing power node, the capability update information may correspond to computing power capability update information. Accordingly, the capability update information includes perception capability update information and / or computing power capability update information. The perception capability update information may include, for example, the original measurement accuracy, updated measurement accuracy, original delay, updated delay, original measurement distance, updated measurement distance, original measurement object azimuth, updated measurement object azimuth, original measurement rate, updated measurement rate, etc. corresponding to the perception node; the computing power capability update information may include, for example, the original computing processing capability, updated computing processing capability, original CPU performance, updated CPU performance, original storage capacity, updated storage capacity, etc.

[0116] In some embodiments, when the capability of the first node is updated, in order to enable the normal execution of the perception service task, the first node may send the capability update information of the first node to the core network device, so that the core network device can determine whether it is necessary to update the perception service session with the UE by analyzing the perception capability information. When the core network device determines that it is necessary to update the perception service session with the UE, it may update the perception nodes and / or computing nodes deployed in the perception service session, or may also update the task allocation information of the perception service task. By updating the perception service session, the updated perception service session can be adapted to the perception computing service, ensuring the rational allocation of resources for the existing perception computing service, so that it can meet the high-quality requirements of data and computing power for the perception computing service that may appear in the 6G era.

[0117] In some embodiments, the first node may include a serving node outside the core network device, or may include a serving network element within the core network device, such as at least one of a UE, a gNB, and a third-party application function (AF). Exemplarily, when the first node is a serving node outside the core network device, such as a UE or a gNB, the first node may send capability update information of the first node to a second network element within the core network device via a control plane AMF.

[0118] In some embodiments, the first node is a service network element in the core network device, such as AF, and the first node can send the capability update information of the first node to the second network element in the core network device through the network element that exposes the NEF capability.

[0119] Step 102: The core network device updates the awareness service session with the UE based on the capability update information.

[0120] In some embodiments, after receiving the capability update information, the core network device may determine whether it will affect the execution of the perception service under the current perception service session based on the updated capability update information, that is, determine whether the perception service session needs to be updated. If the core network device determines through the capability update information that the perception node and / or the computing power node has no substantial modification or has a minor modification, and will not affect the execution of the perception service under the current perception service session, then the perception service session with the UE may not be updated. If the core network device determines through the capability update information that the perception node and / or the computing power node has a major modification (such as a change in perception capability, computing power capability, service update type, etc.), in this case, it may cause the service node under the current perception service session to change, so the perception service session with the UE can be updated to adapt the updated perception service session to the perception computing service.

[0121] This embodiment provides a method for updating a perception service session. When a capability update occurs at the first node, the core network device can update the perception service session created with the UE based on the capability update information. The updated perception service session can be adapted to the perception computing service, ensuring the rational allocation of resources for the existing perception computing service to meet the high-quality data and computing power requirements of the perception computing service that may appear in the 6G era.

[0122] Furthermore, to illustrate the specific execution process of the above-mentioned communication processing system, FIG4 shows a timing diagram of a perception service session update according to an embodiment of the present disclosure. The method is applied to the above-mentioned communication processing system, as shown in FIG4, and may include the following steps:

[0123] 201. A first network element receives capability update information of a first node sent by a second network element.

[0124] In one embodiment of the present disclosure, the first network element may be a data information collection function (DICF) in the core network device, and the second network element may be a data information storage function (DIRF) in the core network device. The second network element may be used to store the perception capability information and / or computing capability information of all first nodes. When the perception capability information and / or computing capability information is updated, the second network element may notify the first network element of the capability update information of the first node through the subscription function. The first network element may determine whether to update the perception service session between the UE and the user plane function UPF through the capability update information. The first network element may also, when determining to update the perception service session between the UE and the user plane function UPF, collaborate with other network elements in the core network device to update the perception service session between the UE and the user plane function UPF based on the capability update information. The first node may be a perception node and / or computing power node (S / C) configured to perform perception service tasks in the perception service session between the UE and the user plane function UPF. 1..n ), when the first node is a perception node, the capability update information may correspond to perception capability update information, and when the first node is a computing power node, the capability update information may correspond to computing power capability update information. In some embodiments of the present disclosure, the perception service session between the UE and the user plane function (UPF) may include an established perception service session.

[0125] In some implementations of the present disclosure, the awareness service session between the UE and the user plane function UPF may include a newly created / to-be-created awareness service session.

[0126] In some embodiments, a second network element in the core network may store sensing capability information and / or computing capability information of a first node. The sensing capability information may include the raw measurement accuracy, raw latency, raw measurement distance, raw measured object azimuth, raw measurement rate, etc. corresponding to the sensing node; and the computing capability information may include, for example, raw computing processing power, raw CPU performance, raw storage capacity, etc. When the sensing capability information and / or computing capability information is updated, the second network element may notify the first network element of the capability update information of the first node through a subscription function. Accordingly, the first network element may receive the capability update information of the first node sent by the second network element.

[0127] Among them, the subscription function is used to support the first network element to call the service of the second network element. The capability update information may include the original capability information and the updated capability information, so that the first network element can perform comparative analysis to determine whether it will affect the current perception service session. Accordingly, the perception capability update information may include the original measurement accuracy, updated measurement accuracy, original latency, updated latency, original measurement distance, updated measurement distance, original measurement object azimuth, updated measurement object azimuth, original measurement rate, updated measurement rate, etc. corresponding to the perception node; the computing power capability update information may include the original computing processing capability, updated computing processing capability, original CPU performance, updated CPU performance, original storage capacity, updated storage capacity, etc.

[0128] 202. The first network element determines whether to update the perception service session between the UE and the user plane function UPF based on the capability update information.

[0129] In one embodiment of the present disclosure, the capability update information is further used to determine whether to update the awareness service session between the UE and a fourth network element. Exemplarily, the fourth network element may include but is not limited to a UPF.

[0130] In some embodiments, after receiving the capability update information of the first node, the first network element may determine whether the first node after the capability update will affect the execution of the perception service task in the current perception service session by comparing the original capability information with the updated capability information. If the first network element determines, by analyzing the capability update information, that the perception node and / or the computing power node has not been substantially modified or has been modified slightly, and will not affect the execution of the perception service under the current perception service session, the perception service session between the first network element and the UE may not be updated, that is, subsequent steps 203 to 211 of the embodiment are not further executed, and the process ends. If the first network element determines, by analyzing the capability update information, that the perception node and / or the computing power node has been significantly modified (for example, information such as perception capability, computing power capability, and service update type has changed), in this case, the service node under the current perception service session may be changed, so the perception service session between the first network element and the UE may be updated by executing subsequent steps 203 to 211 of the embodiment to make the updated perception service session compatible with the perception computing service.

[0131] 203. When it is determined that the awareness service session between the UE and the UPF is to be updated, the first network element generates awareness session modification information based on the capability update information.

[0132] Among them, the perception session modification information may include at least one of the following: an updated first node; an updated second node; an updated task deployment strategy corresponding to the perception service task, wherein the updated task deployment strategy is used to indicate task allocation information of the first node and / or the second node.

[0133] In some embodiments, the awareness session modification information only includes the updated task deployment policy, meaning no first nodes are deleted and no new second nodes are added. The task deployment policy indicates task allocation information for the original first nodes. This means that while all original first nodes are retained and no second nodes are added, awareness service tasks can be reallocated to the original first nodes based on the capability update information.

[0134] In some embodiments, the awareness session modification information includes updated first nodes (e.g., deletion of certain first nodes) and an updated task deployment policy, which indicates task allocation information for the retained first nodes. Specifically, if some first nodes are retained, awareness service tasks can be reallocated based on the updated capability information of the retained first nodes.

[0135] In some embodiments, the awareness session modification information includes updated first nodes (e.g., deleting certain first nodes), updated second nodes (e.g., adding certain second nodes), and an updated task deployment policy. The task deployment policy is used to indicate task allocation information for the retained first nodes and second nodes. Specifically, if some first nodes are retained and at least one second node is added, awareness service tasks can be reallocated based on the capability update information of the retained first nodes and the capability information of the second nodes.

[0136] In some embodiments, the awareness session modification information includes updated second nodes (e.g., adding certain second nodes) and an updated task deployment policy, which indicates task allocation information for the second nodes. Specifically, if all first nodes are removed and at least one second node is added, awareness service tasks can be reallocated based on the capability information of the second nodes.

[0137] 204. The first network element sends a perception service session update request to the third network element. The perception service session update request is used to indicate updating the perception service session between the UE and the UPF. The perception service session update request carries perception session modification information and a perception session unique identifier.

[0138] Among them, the perception session unique identifier is used to determine the perception service session between the UE and the UPF.

[0139] In the disclosed embodiment, the third network element may include an SMF or other network elements in the core network.

[0140] In some embodiments, the first network element sends an awareness service session update request to the third network element, which may instruct the third network element to update the awareness service session corresponding to the awareness session unique identifier based on the awareness session modification information.

[0141] 205. The third network element sends the perception service session update request to the UPF.

[0142] 206. The UPF sends the updated task deployment policy to the first node and / or the second node.

[0143] 207. The UPF sends a perception service session modification message to the third network element. The perception service session modification message includes at least one of a perception service session modification result, a perception session unique identifier, and a modification success identifier.

[0144] In some embodiments, after receiving the perception service session update request, the third network element may send the perception service session update request to the UPF. After receiving the perception service session update request, the UPF may send the updated task deployment policy to the corresponding first node and / or second node, and after the sending is completed, it may send a perception service session modification message to the third network element. The perception service session modification message includes a perception service session modification result, a perception session unique identifier, and a modification success identifier. The perception service session modification result may correspond to the task deployment policy being sent successfully or the task deployment policy being sent incompletely.

[0145] 208. The third network element sends the awareness service session modification message to the radio access network RAN ​​through the access and mobility management function AMF.

[0146] 209. The RAN updates the radio resource configuration of the first node and / or the second node according to the perceived service session modification result.

[0147] In some embodiments, the third network element may send a perception service session modification message to the AMF, which then sends the perception service session modification message to the radio access network (RAN). After receiving the perception service session modification message, the RAN may update the radio resource configuration of the first node and / or the second node, such as updating air interface resources, based on the perception service session modification result carried in the perception service session modification message. The purpose of updating the radio resource configuration is to update the radio resources of the first node and / or the second node, thereby facilitating data exchange between the first node and / or the second node and the core network based on the updated radio resources.

[0148] 210. The RAN sends an awareness service session modification message to the UE.

[0149] 211. RAN sends a session modification confirmation message to the third network element through AMF.

[0150] Among them, UE is a terminal device that has established a perception service session with the user plane function UPF in the core network.

[0151] In some embodiments, the RAN may send a perception service session modification message to the UE. After receiving the perception service session modification message, the UE may send a session modification confirmation message to the RAN. The RAN sends the session modification confirmation message to the AMF, and the AMF sends the session modification confirmation message to the third network element, and the session modification is completed.

[0152] This embodiment provides a method for updating a perception service session. When a capability update occurs at the first node, the core network device can update the perception service session created with the UE based on the capability update information. The updated perception service session can be adapted to the perception computing service, ensuring the rational allocation of resources for the existing perception computing service to meet the high-quality data and computing power requirements of the perception computing service that may appear in the 6G era.

[0153] To illustrate the specific execution process of a core network device, Figure 5 shows a flowchart of a method for establishing a perception service session according to an embodiment of the present disclosure. This method, executed by a first network element in the core network, may include the following steps. The first network element may be a data information collection function (DICF) in the core network device.

[0154] Step 301: Receive capability update information of a first node, where the capability update information includes perception capability update information and / or computing capability update information.

[0155] Among them, the first node may be a perception node and / or a computing power node configured to perform perception service tasks in the perception service session between the first node and the UE. When the first node is a perception node, the capability update information may correspond to perception capability update information. When the first node is a computing power node, the capability update information may correspond to computing power capability update information. Accordingly, the capability update information includes perception capability update information and / or computing power capability update information. The perception capability update information may include the original measurement accuracy, updated measurement accuracy, original delay, updated delay, original measurement distance, updated measurement distance, original measurement object azimuth, updated measurement object azimuth, original measurement rate, updated measurement rate, etc. corresponding to the perception node; the computing power capability update information may include the original computing processing capability, updated computing processing capability, original CPU performance, updated CPU performance, original storage capacity, updated storage capacity, etc.

[0156] In some embodiments, when a first node's capabilities are updated, to enable normal execution of the awareness service task, the first node may send the first node's capability update information to a core network device, so that the core network device can determine whether to update the awareness service session with the UE by analyzing the awareness capability information. The first node may include a service node external to the core network device or a service network element within the core network device, such as at least one of a UE, a gNB, and a third-party application function (AF). Exemplarily, when the first node is a service node external to the core network device, such as a UE or gNB, the first node may send the first node's capability update information to a second network element within the core network device via a traditional control plane AMF. When the first node is a service network element within the core network device, such as an AF, the first node may send the first node's capability update information to the second network element within the core network device via a network element exposed by the NEF capability. The second network element may be a data information repository function (DIRF) within the core network device.

[0157] In some embodiments, a first network element may receive capability update information of a first node sent by a second network element. The second network element may store the perception capability information and / or computing capability information of the first node. When the perception capability information and / or computing capability information is updated, the second network element may notify the first network element of the capability update information of the first node through a subscription function. Accordingly, the first network element may receive the capability update information of the first node sent by the second network element. The subscription function is used to support the first network element's service call to the second network element. The capability update information may include the original capability information and the updated capability information, so that the first network element can perform comparative analysis to determine whether it will affect the current perception service session.

[0158] Step 302: By analyzing the capability update information, determine whether to update the perception service session between the UE and the user plane function UPF.

[0159] In some embodiments, after receiving the capability update information sent by the second network element, the first network element may determine whether the first node after the capability update will affect the execution of the perception service task in the current perception service session by comparing the original capability information with the updated capability information. If the first network element determines, by analyzing the capability update information, that the perception node and / or the computing power node has no substantial modification or has only minor modifications, and will not affect the execution of the perception service under the current perception service session, then the perception service session between the first network element and the UE may not be updated, that is, the subsequent embodiment step 303 is no longer executed, and the process ends; if the first network element determines, by analyzing the capability update information, that the perception node and / or the computing power node has a major modification (for example, the perception capability, computing power capability, service update type, etc. have changed), in this case, it may cause the service node under the current perception service session to change, so the subsequent embodiment step 303 may be executed to update the perception service session between the first network element and the UE so that the updated perception service session is compatible with the perception computing service.

[0160] Step 303: When it is determined that the awareness service session between the UE and the user plane function UPF is to be updated, the awareness service session between the UE and the user plane function UPF is updated based on the capability update information.

[0161] In some embodiments, when the first network element determines to update the perception service session between the UE and the user plane function UPF, it may generate perception session modification information based on the perception capability update information and / or computing power capability update information; and update the perception service session between the UE and the user plane function UPF based on the perception session modification information.

[0162] Among them, the perception session modification information may include at least one of the following: an updated first node; an updated second node; an updated task deployment strategy corresponding to the perception service task, wherein the updated task deployment strategy is used to indicate task allocation information of the first node and / or the second node.

[0163] In some embodiments, the awareness session modification information only includes the updated task deployment policy, meaning no first nodes are deleted and no new second nodes are added. The task deployment policy indicates task allocation information for the original first nodes. Specifically, while retaining all original first nodes and not adding any second nodes, awareness service tasks can be reallocated to the original first nodes based on the capability update information.

[0164] In some embodiments, the awareness session modification information includes updated first nodes (e.g., deletion of certain first nodes) and an updated task deployment policy, which indicates task allocation information for the retained first nodes. Specifically, if some first nodes are retained, awareness service tasks can be reallocated based on the updated capability information of the retained first nodes.

[0165] In some embodiments, the awareness session modification information includes updated first nodes (e.g., deleting certain first nodes), updated second nodes (e.g., adding certain second nodes), and an updated task deployment policy. The task deployment policy is used to indicate task allocation information for the retained first nodes and second nodes. Specifically, if some first nodes are retained and at least one second node is added, awareness service tasks can be reallocated based on the capability update information of the retained first nodes and the capability information of the second nodes.

[0166] In some embodiments, the awareness session modification information includes updated second nodes (e.g., adding certain second nodes) and an updated task deployment policy, which indicates task allocation information for the second nodes. Specifically, if all first nodes are removed and at least one second node is added, awareness service tasks can be reallocated based on the capability information of the second nodes.

[0167] In some embodiments, when updating the perception service session between the UE and the user plane function (UPF) based on the perception session modification information, the first network element may send a perception service session update request to the third network element, so that the third network element updates the perception service session between the UE and the user plane function (UPF) in response to the perception service session update request. The perception service session update request is used to instruct an update of the perception service session between the UE and the user plane function (UPF), and the perception service session update request carries the perception session modification information and the perception session unique identifier. The perception session unique identifier is used to identify the perception service session between the UE and the UPF.

[0168] In the disclosed embodiment, the third network element may include an SMF or other network elements in the core network.

[0169] This embodiment provides a method for updating a perception service session. After receiving capability update information from a perception node and / or a computing node, a first network element can update the perception service session between the UE and the user plane function (UPF) based on the capability update information. By updating the perception service session, the updated perception service session can be adapted to the perception computing service, ensuring the rational allocation of resources for the existing perception computing service to meet the high-quality data and computing power requirements of the perception computing service that may emerge in the 6G era.

[0170] To illustrate the specific execution process of the core network device, Figure 6 shows a flowchart of a method for establishing a perception service session according to an embodiment of the present disclosure. This method, performed by a third network element (a session management function) in the core network, may include the following steps. In the disclosed embodiments, the third network element may include an SMF or other network element in the core network.

[0171] Step 401: Receive a perception service session update request sent by the first network element. The perception service session update request carries perception session modification information and a perception session unique identifier. The perception session modification information is generated by the first network element based on the capability update information of the first node when it determines to update the perception service session between the terminal device UE and the user plane function UPF.

[0172] Among them, the first network element may be a data information collection function (DICF) in the core network device. The first network element may determine whether to update the perception service session between the UE and the user plane function UPF by analyzing the capability update information. The first network element may also coordinate with other network elements in the core network device to update the perception service session between the UE and the user plane function UPF based on the capability update information when determining to update the perception service session between the UE and the user plane function UPF. The first node may be a perception node and / or a computing power node configured to perform perception service tasks in the perception service session between the UE and the UE. When the first node is a perception node, the capability update information may correspond to perception capability update information. When the first node is a computing power node, the capability update information may correspond to computing power capability update information. Accordingly, the capability update information includes perception capability update information and / or computing power capability update information. Perception capability update information may include the original measurement accuracy, updated measurement accuracy, original delay, updated delay, original measurement distance, updated measurement distance, original measurement object azimuth, updated measurement object azimuth, original measurement rate, updated measurement rate, etc. corresponding to the perception node; computing power update information may include the original computing processing capability, updated computing processing capability, original CPU performance, updated CPU performance, original storage capacity, updated storage capacity, etc.

[0173] In some embodiments, the first node may include a serving node outside the core network device, or may include a serving network element within the core network device, such as at least one of a UE, a gNB, and a third-party application function (AF). Exemplarily, when the first node is a serving node outside the core network device, such as a UE or a gNB, the first node may send capability update information of the first node to a second network element within the core network device via a traditional control plane AMF. When the first node is a serving network element within the core network device, such as an AF, the first node may send capability update information of the first node to the second network element within the core network device via a network element that exposes NEF capabilities.

[0174] In some embodiments, when the first network element determines to update the perception service session between the UE and the user plane function (UPF), the first network element may generate perception service session modification information based on the perception capability update information and / or the computing capability update information, and may then send a perception service session update request to a session management function (third network element). Accordingly, the third network element may receive the perception service session update request sent by the first network element.

[0175] Among them, the perception session modification information may include at least one of the following: an updated first node; an updated second node; an updated task deployment strategy corresponding to the perception service task, wherein the updated task deployment strategy is used to indicate task allocation information of the first node and / or the second node.

[0176] In some embodiments, the awareness session modification information only includes the updated task deployment policy, meaning no first nodes are deleted and no new second nodes are added. The task deployment policy indicates task allocation information for the original first nodes. Specifically, while retaining all original first nodes and not adding any second nodes, awareness service tasks can be reallocated to the original first nodes based on the capability update information.

[0177] In some embodiments, the awareness session modification information includes updated first nodes (e.g., deletion of certain first nodes) and an updated task deployment policy, which indicates task allocation information for the retained first nodes. Specifically, if some first nodes are retained, awareness service tasks can be reallocated based on the updated capability information of the retained first nodes.

[0178] In some embodiments, the awareness session modification information includes updated first nodes (e.g., deleting certain first nodes), updated second nodes (e.g., adding certain second nodes), and an updated task deployment policy. The task deployment policy is used to indicate task allocation information for the retained first nodes and second nodes. Specifically, if some first nodes are retained and at least one second node is added, awareness service tasks can be reallocated based on the capability update information of the retained first nodes and the capability information of the second nodes.

[0179] In some embodiments, the awareness session modification information includes updated second nodes (e.g., adding certain second nodes) and an updated task deployment policy, which indicates task allocation information for the second nodes. Specifically, if all first nodes are removed and at least one second node is added, awareness service tasks can be reallocated based on the capability information of the second nodes.

[0180] Step 402: In response to the awareness service session update request, update the awareness service session between the UE and the user plane function UPF.

[0181] In some embodiments, when the third network element updates the perception service session between the UE and the user plane function UPF in response to the perception service session update request, it may include an update for the perception service session within the core network and an update for the user plane.

[0182] For updates to a perception service session within the core network, a third network element may send a perception service session update request to the user plane function (UPF). Upon receiving the perception service session update request, the UPF may send the updated task deployment policy to the corresponding first node and / or second node. After completing the transmission, the UPF may send a perception service session modification message to the third network element. Accordingly, the third network element may receive the perception service session modification message from the UPF. The perception service session modification message includes the perception service session modification result, the perception session unique identifier, and a modification success identifier. The perception service session modification result may correspond to either task deployment policy delivery completion or task deployment policy delivery incomplete. After receiving the perception service session modification message from the UPF, the third network element may send the perception service session modification message to the radio access network (RAN) via the access and mobility management function (AMF), so that the RAN updates the radio resource configuration of the first node and / or second node based on the perception service session modification result. Specifically, the third network element may send the perception service session modification message to the AMF, which in turn sends the perception service session modification message to the radio access network (RAN). After receiving the awareness service session modification message, the RAN may update the radio resource configuration of the first node and / or the second node, such as updating the air interface resources, based on the awareness service session modification result carried in the awareness service session modification message. The purpose of updating the radio resource configuration is to update the air interface resources of the first node and / or the second node to facilitate data exchange between the first node and / or the second node and the core network.

[0183] For updates to the user plane, the third network element can confirm the session modification through the RAN. Specifically, the RAN sends a perception service session modification message to the UE. After receiving the perception service session modification message, the UE can send a session modification confirmation message to the RAN. The RAN sends the session modification confirmation message to the AMF, and the AMF sends the session modification confirmation message to the third network element. Correspondingly, the third network element can receive the UE's session modification confirmation message sent by the RAN through the AMF, and the session modification is completed.

[0184] This embodiment provides a method for updating a perception service session. After receiving a perception service session update request from a first network element, a third network element can respond to the perception service session update request and update the perception service session between the UE and the user plane function (UPF). By updating the perception service session, the updated perception service session can be adapted to the perception computing service, ensuring the rational allocation of resources for the existing perception computing service to meet the high-quality data and computing power requirements of the perception computing service that may emerge in the 6G era.

[0185] To illustrate the specific execution process of the core network device, Figure 7 shows a flow chart of a method for establishing a perception service session according to an embodiment of the present disclosure, which is executed by the radio access network RAN ​​and may include the following steps.

[0186] Step 501: Receive a perception service session modification message.

[0187] The perception service session modification message includes a perception service session modification result, a perception session unique identifier, and a modification success identifier. The perception service session modification result may correspond to completion of task deployment policy delivery or incomplete task deployment policy delivery.

[0188] In some embodiments, the RAN may receive an awareness service session modification message sent by a session management function third network element via an access and mobility management function AMF. Specifically, the third network element may send the awareness service session modification message to the AMF, and the AMF may send the awareness service session modification message to the radio access network RAN.

[0189] In the disclosed embodiment, the third network element may include an SMF or other network elements in the core network.

[0190] Step 502: Update the radio resource configuration of the first node and / or the second node according to the perceived service session modification result.

[0191] The first node is a perception node and / or computing node that executes a perception service task created by a terminal device (UE). The second node is a perception node and / or computing node that is updated based on capability update information of the first node when determining to update a perception service session between the UE and a user plane function (UPF). The first node and / or the second node may be a perception node and / or computing node configured to execute the perception service task in a perception service session with the UE.

[0284] 4) DICF sends the perception service session update request to SMF (Session Management Function), and the request information includes SC Session ID, SC Session modification information, etc.

[0285] 5)SMF sends the awareness service session update request to UPF (User Plane Function).
