[0193] To make the objectives, technical solutions, and advantages of the embodiments of this disclosure clearer, the technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this disclosure, and not all of them. The components of the embodiments of this disclosure described and shown herein can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this disclosure is not intended to limit the scope of the claimed disclosure, but merely represents selected embodiments of this disclosure. All other embodiments obtained by those skilled in the art based on the embodiments of this disclosure without inventive effort are within the scope of protection of this disclosure.

[0194] The following explanations of some terms used in the embodiments of this disclosure are provided to facilitate understanding by those skilled in the art.

[0195] In this disclosure, the term "multiple" refers to two or more objects, and other quantifiers are similar. In this disclosure, the term "and / or" describes the relationship between related objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. The character " / " generally indicates that the preceding and following related objects have an "or" relationship.

[0196] The terms “first,” “second,” and similar terms used in the embodiments of this disclosure do not indicate any order, quantity, or importance, but are merely used to distinguish different thresholds.

[0197] The technical solutions of the embodiments of this disclosure will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this disclosure, and not all embodiments. Based on the embodiments of this disclosure, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this disclosure.

[0198] Research has revealed several instances in traditional 5GC that expose capabilities for access network devices. For example, the Quality of Service Notification Control (QNC) mechanism addresses this by having the Next-Generation Radio Access Network (NG-RAN) notify the Session Management Function (SMF) when the Guaranteed Flow Bit Rate (GFBR) of a QoS flow of a Guaranteed Bit Rate (GBR) type cannot be met. The SMF then forwards the notification to the Policy Control Function (PCF). 5GC then performs rate adaptation processing on the GBR-type QoS flow or deletes the QoS flow. QNC is applicable when the QoS flow is GBR type and the application is capable of rate adjustment. When the NG-RAN determines that the GFBR of a QoS flow can be guaranteed again (at which point a notification indicating that the GFBR can no longer be guaranteed has already been sent, and a similar notification should also be sent to the SMF),...

[0199] Another typical use case is that the delay between User Equipment (UE) and User Plane Function (UPF) can be obtained through messages from the General Packet Radio Service (GPRS) Tunneling Protocol-UserPlane (GTP-U) and reported by the UPF via the SMF, Network Exposure Function (NEF), or its service-oriented interfaces. Based on the above examples, it is clear that in traditional 5GC, different performance data may need to be carried in different information and relayed and transmitted using different network functions. There is no dedicated open method for performance data, resulting in cumbersome signaling and long transmission delays.

[0200] With the introduction of various new service scenarios into the Radio Access Network (RAN) architecture, the 6G network architecture seems to pose more challenges to traditional capability openness technologies, and the aforementioned problems will be more prominent in 6G networks. Therefore, how to allow direct exchange of open capability information between wireless network functions and any network function (NF) or third-party applications within the network to further improve the communication performance of the entire system or specific terminals, thereby meeting more flexible and open service application scenarios, has become one of the urgent challenges to be solved in 6G network technology.

[0201] Based on this, embodiments of this disclosure provide a communication method, network device, apparatus, and storage medium. A first network function entity, acting as a capability openness service provider, can receive requests related to network function openness capabilities directly sent by a second network function entity and return corresponding feedback information. This unifies the signaling transmission paths for different capability openness requirements, avoids transmission delays, and enables direct interaction of the required information for various capability openness needs, thereby improving the communication performance of the entire system or specific terminals. For example, introducing capability openness into a RAN architecture allows direct capability information interaction between the RAN's radio network functions and any NF or third-party application within the network, thus meeting more flexible and open business application scenarios.

[0202] The technical solutions provided in this disclosure are applicable to various systems equipped with non-terrestrial networks (such as satellite networks). For example, applicable systems may include Long Term Evolution (LTE) systems, LTE Frequency Division Duplex (FDD) systems, LTE Time Division Duplex (TDD) systems, Long Term Evolution Advanced (LTE-A) systems, Universal Mobile Telecommunications System (UMTS), Worldwide Interoperability for Microwave Access (WiMAX) systems, and 6G (sixth generation mobile communication technology) systems. These systems may include terminal equipment and network-side equipment. The systems may also include a core network component, such as Evolved Packet Core (EPC) or 5G Core Network (5GC).

[0203] The terminal disclosed in this embodiment may be a device that provides voice and / or data connectivity to a user, a handheld device with wireless connectivity, or other processing devices connected to a wireless modem. The name of the terminal may differ in different systems; for example, in a 6G system, the terminal may be called a User Equipment (UE). The wireless terminal may be a USB storage device, other personal computer memory devices, or a dongle. It may also communicate with one or more core networks (CNs) via a Radio Access Network (RAN). The wireless terminal may be a mobile terminal device, such as a mobile phone (or "cellular" phone) or a computer with a mobile terminal device. For example, it may be a portable, pocket-sized, handheld, computer-embedded, or vehicle-mounted mobile device that exchanges voice and / or data with the radio access network. Examples of such devices include Personal Communication Service (PCS) phones, cordless phones, Session Initiated Protocol (SIP) phones, Wireless Local Loop (WLL) stations, Personal Digital Assistants (PDAs), personal computers, tablets, and Machine-type Communication (MTC) terminal devices. Wireless terminals can also be referred to as systems, subscriber units, subscriber stations, mobile stations, mobile devices, remote stations, access points, remote terminal devices, access terminal devices, user terminal devices, user agents, user devices, and wireless access devices and routers / modems that meet the limitations of this definition, but are not limited to these in the embodiments of this disclosure.

[0204] The first network functional entity involved in the embodiments of this disclosure can be deployed on the RAN side, such as a base station, which can cover the cell providing services to the terminal. Depending on the specific application, the base station can also be called an access point, or a device in the access network that communicates with the wireless terminal device through one or more sectors on the air interface, or other names. The first network functional entity can also coordinate the attribute management of the air interface. For example, the first network functional entity involved in the embodiments of this disclosure can be an evolved network device (eNB or e-NodeB) in a long term evolution (LTE) system, a 5G base station (gNB) in a next generation system, or a Home evolved Node B (HeNB), relay node, femto, pico, network testing equipment, etc., which are not limited in the embodiments of this disclosure. In some network structures, the first network functional entity can include a centralized unit (CU) node and a distributed unit (DU) node, and the centralized unit and distributed unit can also be geographically separated.

[0205] The second network function entity can be deployed on the RAN side, core network side, or third-party application side. On the core network side, the second network function entity is, for example, equipment in the core network (CN) of a mobile communication architecture (such as the 3GPP access architecture of a 5G network). The core network, as the bearer network, provides the interface to the data network, providing user equipment (UE) with communication connections, authentication, management, policy control, and data service delivery. The CN can further include: Access and Mobility Management Function (AMF), Session Management Function (SMF), Authentication Server Function (AUSF), Policy Control Function (PCF), User Plane Function (UPF), and other functions. The AMF function manages UE access and mobility, primarily responsible for UE authentication, UE mobility management, and UE paging.

[0206] Those skilled in the art will understand that, in the above-described method of the specific implementation, the order in which each step is written does not imply a strict execution order and does not constitute any limitation on the implementation process. The specific execution order of each step should be determined by its function and possible internal logic.

[0207] See Figure 1 The diagram illustrates a communication system provided in this embodiment of the present disclosure, including a terminal (such as a UE), a first network function entity (such as a radio network function on the RAN side), and a second network function entity (such as any network function NF or radio capability opening function in the communication network). The first network function entity can establish communication connections with both the second network function entity and the UE. When the second network function entity needs to obtain any information related to the network function's openability (e.g., obtaining communication performance data of any UE), it can initiate a relevant request to the first network function entity. The first network function entity can obtain the relevant communication performance data based on the request and feed it back to the second network function entity. This enables direct interaction of communication performance data, thereby improving the terminal's communication performance. For example, the first network function entity may be a RAN node, and the second network function entity may be an SMF, PCF, etc.

[0208] For the sake of brevity, this article mainly focuses on... Figure 1 The technical solution is described based on the communication system shown. Based on this technical concept, those skilled in the art will be able to implement similar technical solutions based on other communication systems, which will not be elaborated in detail here. Figure 1 This is merely an example and does not limit the number or type of devices included in the system. The network architecture and business scenarios described in this disclosure are for illustrating the technical solutions of this disclosure and do not constitute a limitation on the technical solutions provided in this disclosure. As those skilled in the art will recognize, with the evolution of network architecture and the emergence of new business scenarios, the technical solutions provided in this disclosure are also applicable to similar technical problems.

[0209] To facilitate understanding of this embodiment, a communication method disclosed in this disclosure will first be described in detail. The execution entity of the communication method provided in this disclosure is generally a network device with certain computing capabilities. This network device may include, for example, a network function entity or a server. The network function entity may be, for example, a network function entity on the RAN side, a network function entity on the core network side, etc. In some possible implementations, this communication method can be implemented by a processor calling computer-readable instructions stored in memory.

[0210] The following description uses the first network function entity as an example to illustrate the communication method provided in this embodiment. The first network function entity can be deployed on the RAN side.

[0211] See Figure 2 The diagram shown is a flowchart illustrating a communication method applied to a first network functional entity according to an embodiment of this disclosure. The method includes steps S201 to S202:

[0212] S201: Receive a first request sent by a second network function entity; the first request is used to request information related to the network function's openability.

[0213] In this embodiment of the disclosure, the first network function entity corresponds to the network function on the RAN side. As a producer of capability openness services, it can be used to provide a first function related to the openability of the network function. For example, the first network function entity can be any function related to capability openness, such as wireless network function, wireless distributed function, or wireless centralized user function.

[0214] The second network function entity can be deployed on the RAN side, the core network side, or the third-party application side; this disclosure does not impose specific limitations on these locations. As a consumer of capability openness services, the second network function entity can provide second functions related to the network function's externally open capabilities. These externally open capabilities can be, for example, open capabilities provided to third-party applications or other network function entities. The second network function entity can be, for example, any independent NF or wireless capability openness function in the communication network.

[0215] Network function openability and network function external openability can be viewed as two separate concepts: one is an internally open capability, and the other is an externally open capability. Internally, it refers to the ability to open network functions within the 6G network architecture; externally, it refers to the ability to open capabilities to third-party applications. Whether it's externally open or open network function capability, the information that can be opened can include, for example, data and policies. Data can include, for example, various communication performance data, and policies can include, for example, various communication strategies.

[0216] In one embodiment, the first function may specifically include at least one of communication performance data collection, communication performance data processing, and communication policy execution; and / or, the second function may specifically include performance data monitoring and / or communication policy configuration.

[0217] The collection of communication performance data may include, for example, collecting data on UE-related and / or non-UE-related throughput, transmission latency, packet loss rate, resource utilization, extended reality (XR) service cycle and jitter, and wireless transmission congestion. Communication performance data processing may include, for example, routing, forwarding, and encapsulation of communication performance data. For instance, when the first network function entity sends performance data, the communication performance data processing function may instruct on how to perform routing, how to encapsulate secure data, and how to compress large amounts of data. Communication policy execution may specifically include the receipt and / or execution of communication policies, such as access management, mobility management, and bearer control.

[0218] Performance data monitoring can be used to monitor UE-related and / or non-UE-related performance data; communication policy configuration can be used to configure UE-related QoS policies, access and mobility management policies, etc.

[0219] The first request is initiated by the second network function entity. This request is used to request one or more pieces of information related to the network function's openability, such as requesting to subscribe to one or more pieces of information related to the network function's openability, or requesting to configure one or more communication policies.

[0220] Understandably, the second network function entity initiating the first request can differ depending on the application scenario. For example, when performance data is internally accessible, the second network function entity can be any network function (NF) using the capabilities provided by the first network function entity. When performance data is externally accessible (e.g., to third-party applications), the second network function entity can provide the network functions requested from the first network function entity. In other words, the first network function entity can perform the collection, processing, and execution of wireless communication-related performance data and policies; when it is accessible to external third-party applications, it can provide wireless capability access through the second network function entity.

[0221] In a specific implementation of S201, when any second network function entity has a need to consume information related to the network function's openability, it can initiate a corresponding first request to the first network function entity, after which the first network function entity can receive the first request.

[0222] S202: Send a first message to the second network function entity; the first message includes first feedback information corresponding to the first request.

[0223] Here, the first feedback information may specifically include information collected by the first network function entity that matches the first request, such as communication performance data and the configuration results of communication strategies. The first message may be a response message, which includes the first feedback information collected by the first network function entity.

[0224] In practice, the first network function can collect content matching the information requested in the first request, and send this content as first feedback information to the second network function entity in the form of a first message. After receiving the first message, the second network function entity can perform subsequent processing such as network management and data monitoring on the content included in the first feedback information in the first message.

[0225] In one embodiment, for S201, a first request sent by a second network function entity based on a target protocol stack may be received.

[0226] Here, the target protocol stack can be HyperText Transfer Protocol 2 (HTTP2) / Transport Layer Security (TLS) (optional) / Transmission Control Protocol (TCP) / Internet Protocol (IP) stack, or HTTP3 / Quick UDP Internet Connections (QUIC) / User Datagram Protocol (UDP) / IP stack.

[0227] In practice, the second network function entity can directly send a first request to the first network function entity based on the HTTP2 / TLS (optional) / TCP / IP protocol stack or the HTTP3 / QUIC / UDP / IP protocol stack. Then, the first network function entity can receive the first request sent based on the target protocol stack.

[0228] Furthermore, for S202, a first message can be sent to the second network function entity based on the target protocol stack.

[0229] For example, after determining the first feedback information, the first network function entity can directly send a first message carrying the first feedback information to the second network function entity based on the HTTP2 / TLS (optional) / TCP / IP protocol stack or the HTTP3 / QUIC / UDP / IP protocol stack.

[0230] In this way, the first network function entity and the second network function entity can directly interact on the target protocol stack to open up network capabilities, without having to go through a complex transmission path, which can effectively reduce the complexity of signaling transmission and reduce the interaction latency.

[0231] In one embodiment, the first request includes a first performance data subscription indication, and the first feedback information includes a first performance data report; and / or, the first request includes a first policy configuration indication, and the first feedback information includes a first policy configuration result.

[0232] Here, when the first request is used to request subscription to communication performance data, the payload body in the request may include UE-related and / or non-UE-related first performance data subscription indication information, which is used to indicate the performance data to be subscribed to. For example, the first performance data subscription indication information may indicate a request for subscription to transmission rate, transmission latency, packet loss rate, resource utilization, XR service period and jitter, wireless transmission congestion, etc., wherein the transmission rate may include the minimum guaranteed uplink and downlink rates. Correspondingly, the first feedback information may include a first performance data report composed of performance data collected by the first network function entity.

[0233] When the first request is used to request the configuration of communication policies, the request may include first policy configuration indication information related to the UE. This information indicates which communication policies need to be configured for the UE. For example, policy configuration indication information for access control, handover control, bearer control, etc. Correspondingly, the first feedback information may include the first policy configuration result obtained after the first network function entity configures each communication policy, such as information such as all configurations successful, some configurations successful, or all configurations failed.

[0234] In one embodiment, the first request includes a request related to at least one terminal, and the first request further includes terminal identification information; and / or, the first request includes a request not related to a terminal.

[0235] Here, the first request can be used to instruct communication performance data collection or policy configuration for at least one UE. In this case, the first request is related to at least one UE, and the first request may carry the UE's identification (ID) information. The UE's ID information can be the UE's ID and / or the cell identifier of the cell to which the UE belongs.

[0236] And / or, the first request can also be used to indicate a request for information not related to the UE, such as requesting performance data for the entire system, performance data for a specific service, or the system's operating status. Performance data for a specific service could be, for example, the packet loss rate or usage rate of an immersive service over a certain time period. In this case, the first request is not specifically targeted at a particular UE, so it can be considered a request not related to the terminal.

[0237] It should be noted that non-terminal-related requests typically request information for the entire cell or the entire service; that is, the requested information is not targeted at any specific terminal or one terminal, and therefore does not need to carry a terminal identifier. Furthermore, non-terminal-related requests do not mean that terminal feedback is no longer required. For requests targeting the entire cell, in some cases, it is still necessary for each terminal within the cell to provide relevant performance data, just not for a specific terminal.

[0238] In the case of requesting to configure communication policies, the first request can often be for policy configuration of at least one UE, so the first request can also be related to the UE, and therefore the first request can include the UE's identification information.

[0239] In one embodiment, when the first request includes first performance data subscription indication information, that is, when requesting to subscribe to performance data information, reporting conditions can also be set for the information to be subscribed to, so as to realize data reporting at an appropriate time. Specifically, for S202, when the first reporting condition is met, a first message can be sent to the second network function entity; the first message includes first notification information corresponding to the first request; wherein, the first reporting condition is preset or indicated in the first request.

[0240] Here, the first reporting condition refers to the reporting condition for the information requested in the first request. It can be preset or indicated by the first request. If the first reporting condition is preset, it indicates that this is a general reporting condition; for any first request initiated by any second network function entity, the first network function entity can use this reporting condition to determine whether to report the information. If the first reporting condition is indicated by the first request, it indicates that this reporting condition is set by the second network function entity for the currently sent first request, and this reporting condition applies only to the current first request.

[0241] The first reporting conditions can include overall reporting conditions and reporting conditions for specific communication performance data. Overall reporting conditions can be, for example, immediate reporting or periodic reporting. Reporting conditions for specific communication performance data can include, for example, reporting conditions for transmission delay (e.g., reporting when transmission delay reaches a set delay), reporting conditions for transmission rate (e.g., reporting when transmission rate is less than a target rate), reporting conditions for packet loss rate (e.g., reporting when packet loss rate reaches a preset threshold), and reporting conditions for resource utilization (e.g., reporting when resource utilization exceeds a set utilization rate), etc.

[0242] The first notification information corresponding to the first request may include feedback information when the first reporting condition is met. Here, the specific data to be reported can be performance data, and different performance data may correspond to different reporting conditions. In the case of requesting multiple performance data, there may be multiple reporting conditions. Specifically, when the reporting conditions for each type of performance data are met, the corresponding performance data may be reported, and the first notification information may include the performance data reported separately in multiple batches.

[0243] For example, after receiving the first request, the first network function entity can collect performance data according to the first performance data subscription instruction information to obtain a first performance data report. If the first reporting condition corresponding to the first request is met, a first message including first notification information is sent to the second network function entity. If the performance data requested by the first request includes multiple types, each with corresponding first reporting conditions, then when the first reporting condition for each type of performance data is met, that type of performance data is sent to the second network function entity.

[0244] To facilitate understanding of the embodiments of this disclosure, an example of an internally open data scenario will be used for illustration:

[0245] In scenarios involving internally open data, the first network function entity can be a wireless distributed function, wireless network function, or wireless centralized user function, acting as a provider of open capability services. The second network function entity can be any NF acting as a consumer of open capability services. The NF can directly send a first request to the first network function entity based on the HTTP / TLS (optional) / TCP / IP protocol stack or the HTTP / QUIC / UDP / IP protocol stack. The payload of the first request can include, for example, UE-related and / or non-UE-related first performance data subscription indication information, such as request indications for transmission rate, transmission latency, packet loss rate, resource utilization, XR service period and jitter, and wireless transmission congestion. The transmission rate can include the minimum guaranteed uplink and downlink rates. If the first request is UE-related, it can also include the UE's ID information or UE-related cell ID information.

[0246] The first network function entity can collect data related to the first performance data subscription indication information in the first request, and directly feed back response information (i.e., the first message) to the NF based on the HTTP2 / TLS (optional) / TCP / IP protocol stack or the HTTP3 / QUIC / UDP / IP protocol stack, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc., where the transmission rate can include the minimum guaranteed uplink and downlink rates.

[0247] Optionally, the aforementioned first reporting condition may be included in the first request, for example, including reporting conditions related to various communication performance data requested. In this case, the first network function entity may, upon satisfying the first reporting condition, directly send a first message containing first notification information to the NF based on the HTTP2 / TLS (optional) / TCP / IP protocol stack or the HTTP3 / QUIC / UDP / IP protocol stack. The first notification information may include performance data reports corresponding to UE-related or non-UE-related communication performance data that satisfy the reporting condition, such as: transmission rate, transmission latency, packet loss rate, resource utilization rate, XR service cycle and jitter, wireless transmission congestion, etc., wherein the transmission rate may include the minimum guaranteed uplink and downlink rates.

[0248] Let's take an internal openness strategy as an example to illustrate:

[0249] In an internally open policy scenario, the first network function entity can be a wireless distributed function, wireless network function, or wireless centralized user function, acting as a provider of open capability services. The second network function entity can be any NF acting as a consumer of open capability services. The NF can directly send a first request to the first network function entity based on the HTTP / TLS (optional) / TCP / IP protocol stack or the HTTP / QUIC / UDP / IP protocol stack. The payload of the first request may include, for example, UE-related first policy configuration indication information, such as access control, handover control, and bearer control policy configuration indication information. Furthermore, the first policy configuration indication information may also indicate the relevant UE ID information.

[0250] The first network function entity can perform relevant communication policy configuration operations according to the first policy configuration instruction information in the first request, and directly send the first message to the corresponding NF based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. The first message includes first feedback information, which includes the first policy configuration result. The first policy configuration result can be, for example, information indicating that the configuration is fully successful or partially successful.

[0251] In one embodiment, if the first request includes a first performance data subscription indication, the collection of information related to the network function openability may also require the participation of the terminal. In this case, for step S202, a performance data collection request may be sent to at least one terminal, and a performance data collection response sent by at least one terminal may be received, the performance data collection response including a second performance data report; then a first message may be sent to the second network function entity; the first performance data report in the first message is determined based on the second performance data report.

[0252] Here, the performance data collection request is initiated by the first network function entity to at least one terminal after receiving the first request. The performance data requested in the performance data collection request matches the performance data indicated by the first performance data subscription indication information included in the first request. For example, the performance data collection request may include third performance data subscription indication information, which may be the same as the first performance data subscription indication information, or it may be obtained through further processing of the first performance data subscription indication information, such as further refinement.

[0253] For example, the first network function entity can determine the UEs that need to have their performance data collected based on the UE ID information carried in the first request. Then, the first network function entity can send performance data collection requests to each UE related to the first request based on the first performance data subscription indication information in the first request, using an air interface protocol. After receiving the performance data collection request, each UE can collect the corresponding performance data and generate a second performance data report, and then send a performance data collection response, including the second performance data report, back to the first network function entity via the air interface protocol. Alternatively, the first network function entity can also determine the UEs participating in performance data collection based on the type of performance data requested in the first request; for example, it could be all UEs within the entire cell, or UEs participating in a specific service.

[0254] Furthermore, the first network function entity can generate a first performance data report based on the second performance data report in the performance data collection response, and feed back a first message carrying the first performance data report to the second network function entity. For example, the first network function entity can perform operations such as sorting, summarizing, and filtering the second performance data reports fed back by various terminals to obtain the first performance data report.

[0255] In one embodiment, the second performance data report is submitted when a second reporting condition is met; wherein the second reporting condition is preset or indicated in the performance data collection request.

[0256] Here, the second reporting condition refers to the reporting conditions for the information requested in the performance data collection request. It can be preset or indicated in the performance data collection request. The second reporting condition may be the same as or different from the first reporting condition in some cases. When the second reporting condition is the same as the first reporting condition, after the terminal reports performance data while meeting the second reporting condition, the first network function entity can report the performance data to the second network function entity (while also meeting the first reporting condition). When the second reporting condition is different from the first reporting condition, after the terminal reports performance data while meeting the second reporting condition, the first network function entity can, after receiving the performance data reported by the terminal once or multiple times, uniformly report the received performance data to the second network function entity when the first reporting condition is met. Here, the first network function entity can determine the second reporting condition based on the consumption needs or instructions of the second network function entity and send the second reporting condition along with the performance data collection request to the terminal.

[0257] Wherein, if the second reporting condition is preset, it indicates that the reporting condition is a general reporting condition, and the terminal can use this reporting condition to determine whether to report information for any performance data collection request initiated by any first network function entity. Where the second reporting condition is a performance data collection request indication, the reporting condition can be specific to the current performance data collection request.

[0258] The second reporting condition can include overall reporting conditions and reporting conditions for specific communication performance data. Overall reporting conditions can be, for example, immediate reporting or periodic reporting. Reporting conditions for specific communication performance data can include, for example, reporting conditions for transmission delay, transmission rate, packet loss rate, resource utilization, etc.

[0259] Optionally, the second reporting condition can be related to the first reporting condition. For example, the first request carries the first reporting condition, and the first network function entity can determine the second reporting condition based on the first reporting condition and / or the data consumption needs of the second network function entity. Then, the performance data collection request carrying the second reporting condition is sent to the terminal.

[0260] For example, for any terminal, the terminal can collect corresponding performance data based on the performance data collection request, and then, if the collected performance data determines that the corresponding second reporting condition is met, send the second performance data report corresponding to the collected performance data to the first network function entity in the performance data collection response feedback.

[0261] In one embodiment, with the terminal involved, the first network function entity can also report performance data according to the following steps:

[0262] The receiving terminal sends a second notification message when the performance data update conditions are met; the second notification message includes the updated third performance data report.

[0263] Send a performance data update notification to the second network function entity. The performance data update notification includes an updated performance data report determined based on the third performance data report.

[0264] The performance data update conditions are either preset or indicated in the performance data collection request.

[0265] For example, performance data update conditions can be pre-set for the terminal. When these conditions are met, the terminal can proactively send a performance data report to the first network function entity. Alternatively, the performance data update conditions can be included in the performance data collection request, and these conditions can be determined by the first network function entity based on the consumption needs of the second network function entity.

[0266] The second notification information is a notification actively sent by the terminal, which may include a third performance data report corresponding to performance data that meets the performance data update conditions. For example, if the transmission rate meets the performance data update conditions, a third performance data report related to the transmission rate can be generated and sent to the first network function entity through the second notification information.

[0267] Furthermore, after receiving the second notification information, the first network function entity can send a performance data update notification to the second network function entity. This performance data update notification includes an updated performance data report determined based on the third performance data report. In other words, the performance data update notification is used to indicate the latest updated performance data report from the terminal.

[0268] Optionally, the second network function entity can proactively send a performance data update request to the first network function entity. The first network function entity can then initiate a performance data update request to the terminal based on this request. The terminal can collect the updated performance data and generate a new performance data report, which it then sends back to the first network function entity. The first network function entity can then generate an updated performance data report based on this new report and send it back to the second network function entity. In this way, the second network function entity can request the latest performance data report at any time based on its own needs.

[0269] Optionally, the first network function entity may also proactively send a performance data update request to the terminal. Based on the received performance data update request, the terminal can collect the updated performance data and generate a new performance data report, which is then fed back to the first network function entity. The first network function entity can then generate an updated performance data report based on this new report and send it along with a performance data update notification to the second network function entity, thus notifying the second network function entity of the existence of updated performance data.

[0270] To facilitate understanding of the communication method provided in the embodiments of this disclosure, the following description will be provided in conjunction with different flowcharts:

[0271] In the absence of terminal participation, taking the second network function entity as any NF in the communication network and the first network function entity as the wireless network function as an example, the internal opening process of performance data is explained, such as... Figure 3 The diagram shown is an internal disclosure flowchart for performance data provided in an embodiment of this disclosure, which may include the following steps:

[0272] 301. Any NF in the network can directly send a first request (i.e., ...) to the wireless network function based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. Figure 3 The first request (a performance data subscription request) includes UE-related and / or non-UE-related first performance data subscription indication information, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service period and jitter, wireless transmission congestion, etc. The transmission rate may include the minimum guaranteed uplink and downlink rates. The first network function entity and the second network function entity can interact through Next Radio Network Function (Nrnf) service signaling, such as... Figure 3 As shown.

[0273] In addition, the first request may carry relevant UE ID information or relevant cell identifier information, etc. Optionally, the first request may include first reporting conditions for various performance data.

[0274] 302. The wireless network function can directly send performance data response information to the NF requested in 301 based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. This information can be the first message. The response information includes UE-related and / or non-UE-related performance data reports, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc. Among them, the transmission rate may include the minimum guaranteed uplink and downlink rates.

[0275] 303 (optional step): The wireless network function will, based on the first reporting condition in the first performance data subscription indication information, and if the first reporting condition is met, directly send a message carrying the first notification information (i.e., ...) to the corresponding NF requested in 301, based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. Figure 3 The first message of the performance data notification includes UE-related and / or non-UE-related performance data reports, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc. The transmission rate may include the minimum guaranteed uplink and downlink rates.

[0276] 304 (Optional Step): The wireless network function may, upon determining that the performance data update conditions are met (these conditions may be included in the performance data update request or may be preset), send a performance data update notification to the corresponding NF requested in 301 based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. This notification includes a performance data update report generated by the wireless network function based on the collected performance data.

[0277] In the presence of terminal participation, taking the second network function entity as any NF in the communication network and the first network function entity as the wireless network function as an example, the internal opening process of performance data is explained, such as... Figure 4 The diagram shown illustrates another internal disclosure flowchart for performance data provided in this embodiment, which may include the following steps:

[0278] 401. Any NF in the network can directly send a first request (i.e., a performance data subscription request) to the wireless network function based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. The request contains UE-related / or non-UE-related first performance data subscription indication information, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service period and jitter, wireless transmission congestion, etc. The transmission rate may include the minimum guaranteed uplink and downlink rates.

[0279] In addition, the first request may carry relevant UE ID information or relevant cell identifier information, etc. Optionally, the first request may include first reporting conditions for various performance data.

[0280] 402a. The wireless network function can send a performance data collection request to the UE specified in the first request based on the air interface protocol (i.e., Figure 4 (The wireless data collection request in the first request). This request information may include first performance data subscription indication information related to the UE specified in the first request, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service period and jitter, wireless transmission congestion, etc. Alternatively, the wireless data collection request information may include performance data subscription indication information generated based on the first performance data subscription indication information. Figure 4 The Uu interface in the UE refers to the wireless interface between the UE and the base station (gNodeB), which is a key interface for enabling communication between the UE and the Radio Access Network (RAN).

[0281] 402b. The UE can send a performance data collection response to the Radio Network Function Entity based on the air interface protocol (i.e., Figure 4 The wireless data collection response includes a second performance data report related to the UE specified in the first request, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc.

[0282] Optionally, if the second reporting condition is met, the UE may send a performance data collection response to the radio network function entity based on the air interface protocol. This response may include a second performance data report related to the UE specified in the first request, such as: transmission rate, transmission delay, packet loss rate, resource utilization, XR service cycle and jitter, radio transmission congestion, etc.

[0283] 403. The wireless network function can directly send performance data response information to the NF requested in 401 based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. This information can be the first message. The response information includes a first performance data report related to the UE, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc. Among them, the transmission rate may include the minimum guaranteed uplink and downlink rates, etc. The first performance data report is generated based on the second performance data report.

[0284] Optionally, the wireless network function may, upon meeting the first reporting conditions, directly send a response message to the NF requested in the 401 error message, based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. This response message may be the first message. The response message includes a first performance data report related to the UE.

[0285] 404 (Optional Step): The UE may, if the performance data update conditions are met, send a second notification message to the Radio Network Function Entity based on the air interface protocol (i.e., ...). Figure 4 The second notification includes UE-related third performance data reports, such as transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc.

[0286] 405 (optional step): The wireless network function can directly send a performance data update notification to the NF requested in 401 based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. The performance data update notification includes an updated performance data report determined based on a third-party performance data report, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc.

[0287] In the absence of terminal participation, taking the second network function entity as any NF in the network and the first network function entity as the wireless network function as an example, the internal opening process of the communication policy is explained, such as... Figure 5 The diagram shown is an internal open flowchart of a communication strategy provided in an embodiment of this disclosure, which may include the following steps:

[0288] 501. Any NF in the network can directly send a first request, including first policy configuration indication information, to the wireless network function based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. Figure 5The first request contains at least one policy configuration indication information related to at least one UE, such as policy configuration indication information for access control, handover control, bearer control, etc. Additionally, the request may include the ID information of the relevant UE. Any NF can interact with the radio network function through Nrnf service signaling to transmit the communication policy configuration request to the radio network function.

[0289] 502. The wireless network function executes corresponding communication strategies, such as new access control, handover control, and bearer control mechanisms.

[0290] 503. The wireless network function can directly send the first message (i.e., ...) to the corresponding NF requested in 501 based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. Figure 5 The communication strategy configuration feedback includes a first message containing first feedback information, which in turn includes a first strategy configuration result. The first strategy configuration result may include, for example, information indicating that the configuration was fully successful or partially successful.

[0291] Furthermore, since the communication method provided in this disclosure involves the interaction between a first network functional entity and a second network functional entity, this disclosure also provides a communication method applied to the second network functional entity. For example... Figure 6 The diagram shown is a flowchart illustrating a communication method applied to a second network functional entity according to an embodiment of this disclosure. The method includes steps S601 to S602:

[0292] S601: Send a first request to the first network function entity; the first request is used to request information related to the network function's openability.

[0293] S602: Receive a first message sent by a first network function entity; the first message includes first feedback information corresponding to the first request.

[0294] For the specific implementation process of S601 to S602 mentioned above, please refer to S201 to S202 above, which will not be repeated here.

[0295] In one embodiment, a first network function entity is used to provide a first function related to the network function's openability; and a second network function entity is used to provide a second function related to the network function's external openability.

[0296] In one embodiment, the first function includes at least one of communication performance data collection, communication performance data processing, and communication policy execution; and / or, the second function includes performance data monitoring and / or communication policy configuration.

[0297] In one embodiment, S601 described above can be implemented according to the following steps:

[0298] A first request is sent to the first network function entity based on the target protocol stack;

[0299] Regarding the above S602, the following steps can be taken:

[0300] Receive the first message sent by the first network function entity based on the target protocol stack.

[0301] That is, the first network functional entity and the second network functional entity can exchange information through the target protocol stack.

[0302] In one embodiment, the first request includes a first performance data subscription indication, and the first feedback information includes a first performance data report; and / or, the first request includes a first policy configuration indication, and the first feedback information includes a first policy configuration result.

[0303] In one embodiment, the first message is reported when a first reporting condition is met; the first message includes first notification information corresponding to the first request; wherein the first reporting condition is preset or indicated in the first request.

[0304] Here, the first message can be sent by the first network function entity to the second network function entity based on the collected performance data, provided that the first reporting condition is met. In this case, the first message includes first notification information corresponding to the first request, which is used to notify the performance data report corresponding to the performance data that meets the first reporting condition.

[0305] In one embodiment, performance data or communication strategies may be made available to third-party applications, and the second network function entity may provide second functions related to the network function's externally accessible capabilities to the third-party applications. In the presence of third-party applications, the second network function entity may provide wireless capability opening functions.

[0306] The above-mentioned S601 can be implemented according to the following steps:

[0307] S601-1: Receive a second request sent by a third-party application server; the second request is used to request information related to the network function openability capability.

[0308] Here, the second request is initiated by the third-party application server to the second network function entity when it determines that it needs to use the network function's openability. The second request can be used to request information related to the network function's openability. Since the third-party application server cannot directly interact with the first network function entity, it needs to act as an intermediary through the second network function entity, which can provide second functions related to the network function's external openability, to enable access to the data and policies collected by the first function provided by the first network function entity.

[0309] In practice, when a third-party application server needs to consume information related to the network function's open capabilities, it can directly call the second network function entity via the Application Programming Interface (API) to send a second request. The second network function entity can then receive the second request.

[0310] S601-2: Based on the second request, send the first request to the first network function entity.

[0311] In practice, the second network function entity can generate a corresponding first request based on the information indicated by the first request, and send the first request to the first network function entity. Afterwards, it can receive the first message sent by the first network function entity.

[0312] Furthermore, after receiving the first message sent by the first network function entity, the second network function entity can also send a second message to the third-party application server; the second message includes second feedback information corresponding to the second request, and the second feedback information is determined based on the first feedback information.

[0313] For example, the second network function entity can generate second feedback information that matches the second request based on the first feedback information in the first message. For instance, the first feedback information can be processed through one or more data processing methods, such as summarizing and converting information formats, to obtain the second feedback information. Then, the second network function entity can send a second message containing the second feedback information to a third-party application server via an API interface.

[0314] The second network function entity can decide how to provide feedback to the third-party application server based on the consumption situation. For example, it can provide unified feedback to the third-party application server after receiving the first feedback information corresponding to all the information requested by the second request, or it can provide feedback once after receiving the first feedback information corresponding to any of the information requested by the second request, or it can provide periodic feedback to the third-party application.

[0315] Optionally, the second request may include a third reporting condition set by the third-party application server. This third reporting condition can be determined based on the consumption needs of the third-party application or can be pre-agreed upon. The second network function entity can send a second message to the third-party application server if the third reporting condition is met. The first reporting condition in the first request can be generated based on the third reporting condition. When a terminal is involved, the second reporting condition in the performance data collection request can be determined based on at least one of the second reporting condition, the third reporting condition, and the consumption needs of the second network function entity.

[0316] Understandably, the first, second, or third reporting conditions can be preset conditions or generated by the party initiating the corresponding request.

[0317] In one embodiment, the second request may include second performance data subscription indication information, and the second feedback information may include a third performance data report; and / or, the second request may include second policy configuration indication information, and the second feedback information may include a second policy configuration result.

[0318] Here, when the second request is used to request subscription to communication performance data, the payload of the second request may include UE-related and / or non-UE-related second performance data subscription indication information, which is used to indicate the performance data to be subscribed to. For example, the second performance data subscription indication information may indicate a request for subscription to transmission rate, transmission latency, packet loss rate, resource utilization, XR service period and jitter, wireless transmission congestion, etc., wherein the transmission rate may include the minimum guaranteed uplink and downlink rates. Correspondingly, the second feedback information may include a third performance data report generated by the second network function entity based on the first performance data report. For example, the second network function entity may process the first performance data report by performing data sorting, format conversion, compression and segmentation, etc., to obtain the third performance data report, and feed it back to the third-party application through a second message. When a terminal is involved, the first performance data report may be determined based on the second performance data report fed back by the terminal, and the third performance data report may be determined based on the first performance data report.

[0319] Understandably, when the second request includes the second performance data subscription instruction information, the first request includes the first performance data subscription instruction information generated based on the second performance data subscription instruction information, the first feedback information includes the first performance data report, and the second feedback information includes the third performance data report.

[0320] When the second request is used to request the configuration of communication policies, the request may include second policy configuration indication information related to the UE. This information indicates which communication policies need to be configured for the UE. For example, policy configuration indication information for access control, handover control, bearer control, etc. Correspondingly, the second feedback information may include the second policy configuration result obtained after the first network function entity configures each communication policy, such as information indicating all configurations were successful, some configurations were successful, or all configurations failed. The second policy configuration result can be determined based on the first policy configuration result in the first message.

[0321] Understandably, when the second request includes the second policy configuration instruction information, the first request includes the first policy configuration instruction information generated based on the second policy configuration instruction information; the first feedback information may include the first policy configuration result, and the second feedback information may include the second policy configuration result.

[0322] That is, when the second request requests the collection of communication performance data, the first request is also a request to collect communication performance data; when the second request requests the configuration of communication policies, the first request is also a request to configure communication policies.

[0323] In one embodiment, the first request includes a request related to at least one terminal, and the first request further includes terminal identification information; and / or, the first request includes a request not related to a terminal.

[0324] Understandably, the second request may include a request related to at least one terminal, and the second request may also include terminal identification information; and / or, the second request may include a request not related to a terminal. If the second request is related to at least one terminal, the first request is also related to a terminal, and the related terminal is determined according to the second request, and the terminal identification information included in the first request is determined according to the terminal identification information in the second request. If the second request is not related to a terminal, the first request is also not related to a terminal.

[0325] Optionally, after receiving a performance data update notification, the second network function entity can send performance data feedback to the third-party application server via an API interface, based on the updated performance data report included in the performance data update notification. This feedback is used to notify the third-party application server that performance data has been updated. Specifically, the second network function entity can provide feedback to the third-party application server once after receiving multiple performance data update notifications, based on the updated performance data reports from the multiple notifications; alternatively, it can provide feedback immediately upon receiving a performance data update notification; or it can provide feedback according to a set period, based on the updated performance data reports from the performance data update notifications received within that period. This embodiment does not specifically limit the method by which the second network function entity provides feedback to the third-party application server after receiving a performance data update notification; it can be determined based on the consumption needs of the second network function entity or the third-party application server.

[0326] To facilitate understanding of the embodiments of this disclosure, an example of publicly available data will be used for illustration:

[0327] In scenarios where data is made publicly available, the first network function entity can be a wireless distributed function, wireless network function, or wireless centralized user function that acts as a provider of open capability services. The second network function entity provides the network function's publicly available capabilities, specifically wireless capability open functions.

[0328] As a third-party application server that serves as a consumer of the capability openness service, it can directly send a second request to the wireless capability openness function via API calls. This second request includes UE-related and / or non-UE-related second performance data subscription indication information. If the second request is UE-related, it may also include relevant UE ID information or UE-related cell ID information.

[0329] Based on the aforementioned second request, the wireless capability opening function can directly send a first request to the first network function entity, such as the wireless distributed function, wireless network function, or wireless centralized user function, using the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. The first request is determined according to the second request. The payload of the first request may include, for example, UE-related and / or non-UE-related first performance data subscription indication information, such as requests for transmission rate, transmission latency, packet loss rate, resource utilization, XR service period and jitter, and wireless transmission congestion status. The transmission rate may include the minimum guaranteed uplink and downlink rates. Furthermore, when the first request is UE-related, it may also include the UE's ID information or UE-related cell ID information.

[0330] The first network function entity can collect data related to the first performance data subscription indication information in the first request, and directly feed back response information (i.e., the first message) to the wireless capability opening function based on the HTTP2 / TLS (optional) / TCP / IP protocol stack or the HTTP3 / QUIC / UDP / IP protocol stack. The information includes UE-related and / or non-UE-related performance data reports, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc. The transmission rate may include the minimum guaranteed uplink and downlink rates.

[0331] Optionally, the aforementioned first reporting condition may be included in the first request, for example, including reporting conditions related to various communication performance data requested. In this case, the first network function entity may, upon satisfying the first reporting condition, directly send a first message containing first notification information to the wireless capability opening function based on the HTTP2 / TLS (optional) / TCP / IP protocol stack or the HTTP3 / QUIC / UDP / IP protocol stack. The first notification information may include performance data reports corresponding to UE-related or non-UE-related communication performance data that meet the reporting condition, such as: transmission rate, transmission latency, packet loss rate, resource utilization rate, XR service period and jitter, wireless transmission congestion, etc., wherein the transmission rate may include the minimum guaranteed uplink and downlink rates.

[0332] The wireless capability opening function can send a second message to the corresponding third-party application server based on API calls; the second message includes second feedback information corresponding to the second request, which is determined based on the first feedback information, thereby realizing the feedback of performance data reports to the third-party application server.

[0333] Let's take the example of an open-door policy to illustrate this further:

[0334] In the context of an open strategy, the first network function entity can be a wireless distributed function, wireless network function, or wireless centralized user function that acts as a provider of open capability services. The second network function entity provides the network function's open capabilities, specifically the wireless capability open function.

[0335] As a third-party application server serving as a consumer of the capability openness service, it can directly send a second request to the wireless capability openness function via API calls. This second request includes UE-related second policy configuration indication information, such as policy configuration indication information for access control, handover control, and bearer control. In addition, the second policy configuration indication information can also indicate the relevant UE ID information.

[0336] Based on the aforementioned second request, the wireless capability opening function can directly send a first request to the first network function entity, such as the wireless distributed function, wireless network function, or wireless centralized user function, using either the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. The first request is determined according to the second request. The payload of the first request may include, for example, UE-related first policy configuration indication information, such as policy configuration indication information for access control, handover control, and bearer control. Furthermore, the first policy configuration indication information may also indicate relevant UE ID information, etc., and can be determined based on the second policy configuration indication information.

[0337] The first network function entity can perform relevant communication policy configuration operations according to the first policy configuration instruction information in the first request, and directly send a first message to the corresponding wireless capability opening function based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. The first message includes first feedback information, which includes the first policy configuration result. The first policy configuration result can be, for example, information indicating that the configuration is fully successful or partially successful.

[0338] The wireless capability opening function can send a second message to the corresponding third-party application server based on API calls; the second message includes second feedback information corresponding to the second request, and the second feedback information includes the second policy configuration result. The second policy configuration result is determined according to the first policy configuration result, thereby realizing the feedback of policy configuration result to the third-party application server.

[0339] To facilitate understanding of the communication method provided in the embodiments of this disclosure, the following description will be provided in conjunction with different flowcharts:

[0340] In the absence of terminal participation, taking the second network function entity as the wireless capability opening function and the first network function entity as the wireless network function as an example, the process of opening performance data to the outside world is explained, such as... Figure 7 The diagram shown is a flowchart illustrating the process of publicly disclosing performance data according to an embodiment of this disclosure, which may include the following steps:

[0345] 704 (optional step): The wireless network function will, based on the first reporting condition in the first performance data subscription indication information, and if the first reporting condition is met, directly send a first message carrying the first notification information (i.e., ...) based on the wireless capability opening function requested from 702 using the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. Figure 7 The first notification information includes UE-related and / or non-UE-related performance data reports, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc. The transmission rate may include the minimum guaranteed uplink and downlink rates.

[0346] exist Figure 7 In this context, the wireless capability open function and the wireless network function can interact through Nrnf service signaling. For example, they can use Nrnf service signaling to transmit performance data subscription requests, performance data response information, and performance data notifications.

[0347] 705. The wireless capability opening function can, based on the aforementioned API calls, send a second message (i.e., ...) to the corresponding third-party application server. Figure 7 The second message includes second feedback information corresponding to the second request. The second feedback information is determined based on the first feedback information and may include a third performance data report.

[0348] Optionally, the wireless capability opening function can, based on a third reporting condition, send a second message to the corresponding third-party application server based on the aforementioned API call if the third reporting condition is met.

[0349] In cases involving terminal participation, taking the second network function entity as the wireless capability opening function and the first network function entity as the wireless network function as an example, the process of opening performance data to the outside world is explained, such as... Figure 8 The diagram shown illustrates another flowchart for disclosing performance data according to an embodiment of this disclosure, which may include the following steps:

[0350] 801. Third-party application servers can directly send a second request (i.e., ...) to the wireless capability opening function based on API calls.

[0352] In addition, the first request may carry relevant UE ID information or relevant cell identifier information, etc. Optionally, the first request may include first reporting conditions for various performance data.

[0353] 803a. The wireless network function can send a performance data collection request to the UE specified in the first request based on the air interface protocol (i.e., Figure 8 (The wireless data collection request in the first request). This request information may include first performance data subscription indication information related to the UE specified in the first request, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service period and jitter, wireless transmission congestion, etc. Alternatively, the wireless data collection request information may include performance data subscription indication information generated based on the first performance data subscription indication information.

This message can be the first message. The response message includes a first performance data report related to the UE.

[0358] 805 (Optional Step): The UE may, if the performance data update conditions are met, send a second notification message to the radio network function entity based on the air interface protocol (i.e., ...). Figure 8 The second notification includes UE-related third performance data reports, such as transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, and wireless transmission congestion. Figure 8 In this system, the wireless network function and the UE can communicate via the Uu interface. For example, the two can communicate via the Uu interface to request wireless data collection, respond to wireless data collection, and notify wireless data updates.

[0359] 806 (optional step): The wireless network function can directly send performance data update notifications to the wireless capability opening function in 802 based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. The performance data update notification includes the updated performance data report determined based on the third performance data report, such as: transmission rate, transmission latency, packet loss rate, resource utilization, XR service cycle and jitter, wireless transmission congestion, etc.

[0360] exist Figure 8 In this context, the wireless capability open function and the wireless network function can interact through Nrnf service signaling. For example, they can use Nrnf service signaling to transmit performance data subscription requests, performance data response information, and performance data update notifications.

[0361] 807. The wireless capability opening function can, based on the aforementioned API calls, send a second message (i.e., ...) to the corresponding third-party application server.

The second feedback information is determined based on the first feedback information and may include a third performance data report.

[0362] Optionally, the wireless capability opening function can, based on a third reporting condition, send a second message to the corresponding third-party application server based on the aforementioned API call if the third reporting condition is met.

[0363] In the presence of terminal participation, taking the second network function entity as the wireless capability opening function and the first network function entity as the wireless network function as an example, the process of opening up the communication policy is explained, such as... Figure 9 The diagram shown is a flowchart of a communication strategy disclosed in this embodiment, which may include the following steps:

[0364] 901. Third-party application servers can directly send a second request (i.e., ...) to the wireless capability opening function based on API calls. Figure 9 The second request (a policy configuration request) contains second policy configuration indication information related to the UE. Additionally, the second request may carry the relevant UE ID information.

[0365] 902. The wireless capability opening function can directly send the first request (i.e., ...) to the wireless network function based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack. Figure 9 (Communication policy configuration request in the middle), in Figure 9 In this context, the first request is represented by a communication policy configuration request. The request includes UE-related first policy configuration indication information, such as configuration indication information for access control, handover control, bearer control, etc. In addition, the first request may also include relevant UE ID information, etc.

[0366] 903. The wireless network function executes corresponding communication strategies, such as new access control, handover control, and bearer control mechanisms.

[0367] 904. The wireless network function can directly send response information to the corresponding wireless capability opening function in 902 based on the HTTP2 / TLS (optional) / TCP / IP or HTTP3 / QUIC / UDP / IP protocol stack (i.e., Figure 9 The communication strategy configuration feedback (in the context) can be a first message. The first message includes first feedback information, which in turn includes a first strategy configuration result. This first strategy configuration result may, for example, include information indicating that the configuration was fully successful or partially successful. Figure 9 In this context, the wireless capability opening function and the wireless network function can interact through Nrnf service signaling. For example, the two can interact through Nrnf service signaling to request and receive communication policy configuration feedback.

[0368] 905. The wireless capability opening function can, based on the aforementioned API calls, send a second message (i.e., ...) to the corresponding third-party application server. Figure 9 The second message includes second feedback information corresponding to the second request. The second feedback information is determined based on the first feedback information and may include the second strategy configuration result.

[0369] Thus, in this embodiment of the disclosure, the first network function entity is used to provide a first function related to the network function openability capability, which may specifically include at least one of the following functions: communication performance data collection (e.g., UE-related / or non-UE-related throughput, transmission latency, packet loss rate, resource utilization, etc.), communication performance data processing (e.g., routing forwarding, encapsulation, etc.), and receiving and / or executing communication policies (e.g., access management, mobility, bearer control, etc.).

[0370] The second network function entity provides secondary functions related to the network functions' externally accessible capabilities. Specifically, it includes at least one of the following functions: performance data monitoring (for monitoring UE-related and / or non-UE-related communication performance data), and communication policy configuration (for configuring UE-related QoS policies, policies affecting access and mobility management, etc.). By introducing capability openness into the RAN architecture, allowing direct interaction of capability information, such as performance data or communication policies, between the radio network function and any NF or third-party application server within the network, can better improve the communication performance of the entire system or specific terminals, thereby further meeting more flexible and open business application scenarios.
