[0075] To meet the challenges of wireless broadband technology and maintain the leading edge of the 3rd Generation Partnership Project (3GPP) network, the 3GPP standards group has developed a next-generation mobile communications network system architecture, known as the fifth-generation (5G) network architecture. This architecture not only supports access to the 5G core network (CN) using 3GPP-defined radio access technologies (such as Long Term Evolution (LTE) and 5G Radio Access Network (RAN)), but also supports access to the core network using non-3GPP access technologies via the non-3GPP interworking function (N3IWF) or the next-generation packet data gateway (ngPDG).

[0076] Figure 1(a) shows a schematic diagram of a 5G network architecture based on a service-oriented architecture. The 5G network architecture shown in Figure 1(a) may include access network equipment and core network equipment. Terminal devices access the data network (DN) through the access network equipment and core network equipment. Among them, the core network equipment includes but is not limited to some or all of the following network elements: authentication server function (AUSF) network element, unified data management (UDM) network element, unified data repository (UDR) network element, network storage function (NRF) network element (not shown in the figure), network exposure function (NEF) network element (not shown in the figure), application function (AF) network element, policy control function (PCF) network element, access and mobility management function (AMF) network element, session management function (SMF) network element, user plane function (UPF) network element, sensing function (SF) network element, network data analysis function (NWDAF) network element (not shown in the figure).

[0077] The terminal device can be user equipment (UE), a mobile station, a mobile terminal device, etc. The terminal device can be widely used in various scenarios, for example, device-to-device (D2D), vehicle to everything (V2X) communication, machine-type communication (MTC), Internet of Things (IOT), virtual reality, augmented reality, industrial control, autonomous driving, telemedicine, smart grid, smart furniture, smart office, smart wearable, smart transportation, smart city, etc. The terminal device can be a mobile phone, a tablet computer, a computer with wireless transceiver function, a wearable device, a vehicle, an urban air vehicle (such as an unmanned aerial vehicle, a helicopter, etc.), a ship, a robot, a robotic arm, a smart home device, etc. For the sake of convenience, this application uses UE as an example of a terminal device for illustration, and any UE appearing in any subsequent position can be replaced by a terminal device.

[0078] Access network equipment can be radio access network equipment (RAN equipment) or wired access network equipment. Radio access network equipment includes 3GPP access network equipment, untrusted non-3GPP access network equipment, and trusted non-3GPP access network equipment. 3GPP access network equipment includes, but is not limited to, evolved NodeBs (eNodeBs) in LTE, next-generation NodeBs (gNBs) in 5G mobile communication systems, base stations in future mobile communication systems, or modules or units that perform some of the functions of base stations, such as centralized units (CUs) and distributed units (DUs). Untrusted non-3GPP access network equipment includes, but is not limited to, untrusted non-3GPP access gateways or N3IWFs, untrusted wireless local area network (WLAN) access points (APs), switches, and routers. Trusted non-3GPP access network equipment includes, but is not limited to, trusted non-3GPP access gateways, trusted WLAN APs, switches, and routers. Wired access network equipment includes, but is not limited to, wireline access gateways, fixed-line network equipment, switches, and routers. For ease of explanation, this application uses a base station as an example of an access network device, and any base station appearing at any subsequent location can be replaced by an access network device.

[0079] Base stations and UEs can be fixed or mobile. They can be deployed on land, indoors or outdoors, handheld or vehicle-mounted; on water; or in the air on aircraft, balloons, and satellites. The embodiments of this application do not limit the application scenarios of base stations and UEs.

[0080] The AMF network element performs functions such as mobility management and access authentication / authorization. It is also responsible for transferring user policies between the UE and the PCF.

[0081] The SMF network element includes functions such as performing session management, executing control policies issued by the PCF network element, selecting the UPF network element, or allocating the UE's Internet Protocol (IP) address.

[0082] The UPF network element includes functions such as user plane data forwarding, session / flow-level billing statistics, or bandwidth limitation.

[0083] UDM network elements include functions such as executing and managing contract data or user access authorization.

[0084] UDR includes functions for accessing data such as contract data, policy data, or application data.

[0085] NEF network element is used to support the opening of capabilities and events.

[0086] The AF network element communicates application-side requirements to the network, such as QoS requirements or user status event subscriptions. The AF can be a third-party functional entity or an application service deployed by a carrier, such as the IP Multimedia Subsystem (IMS) voice call service. AF network elements include those within the core network (i.e., the carrier's AF network element) and third-party AF network elements (such as an enterprise's application server).

[0087] The PCF network element includes policy control functions such as billing for sessions and service flow levels, QoS bandwidth guarantee and mobility management, or UE policy decision-making. PCF network elements include access and mobility management policy control function (AM PCF) network element and session management policy control function (SM PCF) network element. Among them, the AM PCF network element is used to formulate AM policy and user policy for UE. The AM PCF network element can also be called a policy control network element that provides services for UE (PCF for a UE). The SM PCF network element is used to formulate session management policy (SMpolicy) for the session. The SM PCF network element can also be called a policy control network element that provides services for protocol data unit (PDU) sessions ((PCF for a PDU session))).

[0088] NRF network elements can be used to provide network element discovery functions, providing network element information corresponding to the network element type based on requests from other network elements. NRF network elements also provide network element management services, such as network element registration, update, deregistration, or network element status subscription and push.

[0089] The SF network element can generate a perception map based on the acquired perception measurement data.

[0090] The AUSF network element is responsible for authenticating users to determine whether users or devices are allowed to access the network.

[0091] The NWDAF network element can analyze the collected data to obtain analysis results.

[0092] A DN is a network located outside of a carrier network. A carrier network can connect to multiple DNs, and a variety of services can be deployed on the DN, providing UEs with data and / or voice services. For example, a DN is the private network of a smart factory. Sensors installed in the workshop can be UEs. The DN houses a control server for these sensors, which can provide services to the sensors. The sensors can communicate with the control server, receive instructions from the control server, and transmit collected sensor data to the control server based on the instructions. Another example is a DN that is a company's internal office network. An employee's mobile phone or computer can be a UE, allowing them to access information and data resources on the company's internal office network.

[0115] QoS refers to the network's ability to leverage various underlying technologies to provide enhanced service for specified network communications. It serves as a network security mechanism and a technique for addressing issues such as latency and congestion. QoS guarantees are crucial for networks with limited capacity, especially for streaming multimedia services, as these often require fixed transmission rates and are sensitive to latency. Optimizing service QoS to enhance the communication experience remains a critical issue requiring ongoing attention.

[0116] To solve the above problems, this application provides multiple solutions, which are described below.

[0117] Figure 2(a) is a flow chart of a communication method provided in an embodiment of the present application. The method includes the following steps:

[0118] In step 201a, the PCF receives a first request, where the first request includes requested QoS parameters.

[0119] Specifically, the PCF may receive a first request from a UE, SMF, NEF, AF or other network elements.

[0120] As an implementation method, step 201a may also be replaced by: the PCF receives a first request, the first request includes indication information for indicating requested QoS parameters; the PCF obtains the requested QoS parameters according to the indication information.

[0121] Optionally, the first request is a first request for a UE; or in other words, the first request includes a QoS parameter requested for the UE. The UE here is the UE in step 202a.

[0122] Optionally, the requested QoS parameters include a QoS reference or explicit QoS parameter content (individual QoS parameters), and optionally also include alternative service requirements (Alternative Service Requirements) of the requested QoS parameters, which will not be described in detail in subsequent embodiments.

[0123] Step 202a: The PCF obtains a perception map corresponding to the first area where the UE is located.

[0124] The perception map is information about the state of objects in the first area acquired through perception, and is used to reflect environmental information about the first area, such as the number of objects, object distribution, object type, object size, object outline, object movement speed, or object movement direction within the first area. The perception map is also referred to as a perception result. The definition and function of the perception map are explained here and will not be elaborated on later.

[0125] As an implementation method, the above-mentioned first request also includes the identification information of the UE (i.e., UE ID), then the step 202a is specifically as follows: PCF sends a perception map request to SF, the perception map request includes the UE ID, and then SF determines the perception map based on the UE ID and sends the perception map to PCF. Exemplarily, SF determines the first perception map based on the UE ID, which can be specifically as follows: SF sends a location information request to AMF, the location information request includes the UE ID, which is used to request the location information of the UE, and AMF sends a location information response to SF, the location information response carries the location information of the UE; then SF determines the information of the first area where the UE is located based on the location information of the UE; then SF sends a request message to the perception device, the request message includes the information of the first area, and the perception device sends a response message to SF, the response message includes the perception measurement data corresponding to the first area; then SF generates a perception map based on the perception measurement data. Among them, the way in which SF obtains the perception measurement data corresponding to the first area described here is only an example. There are actually other ways. For example, SF sends a request message to the perception device, which includes the location information of the UE. The perception device determines the information of the first area based on the location information of the UE. The perception device obtains the perception measurement data corresponding to the first area and sends a response message to SF, which includes the perception measurement data corresponding to the first area.

[0126] As another implementation method, if the first request also includes the UE's location information, then step 202a is specifically as follows: the PCF sends a perception map request to the SF, where the perception map request includes the UE's location information; the SF then determines the perception map based on the UE's location information and sends the perception map to the PCF. Exemplarily, the SF determines the first perception map based on the UE's location information. Specifically, this may be as follows: the SF determines information about the first area where the UE is located based on the UE's location information; the SF then sends a request message to the perception device, where the request message includes information about the first area; the perception device sends a response message to the SF, where the response message includes perception measurement data corresponding to the first area; and the SF generates the perception map based on the perception measurement data. The method described here for the SF to obtain the perception measurement data corresponding to the first area is merely an example; there are other methods. For example, the SF sends a request message to the perception device, where the request message includes the UE's location information; the perception device determines information about the first area based on the UE's location information; the perception device obtains perception measurement data corresponding to the first area; and sends a response message to the SF, where the response message includes the perception measurement data corresponding to the first area.

[0127] As another implementation method, if the first request also includes information about the first area, then step 202a specifically involves the PCF sending a perception map request to the SF, the perception map request including information about the first area. The SF then determines a perception map based on the information about the first area and sends the perception map to the PCF. For example, the SF may determine the first perception map based on the information about the first area by sending a request message to the perception device, the request message including information about the first area, and the perception device sending a response message to the SF, the response message including perception measurement data corresponding to the first area. The SF then generates the perception map based on the perception measurement data.

[0128] It is understandable that the above-mentioned perception map request can be understood as a request for obtaining a perception map or a request for triggering the SF to initiate a perception process. This application does not limit the name of the request. The perception map request will not be described in detail below.

[0129] In the embodiments of the present application, the sensing device may be integrated into the base station, that is, the sensing device is a functional module of the base station. Alternatively, the sensing device may be an independent physical device, such as an independent terminal device. This application does not limit this.

[0130] As an implementation method, the first request also includes instruction information for instructing to optimize communication through network awareness. In this case, step 202a specifically includes: the PCF obtains the awareness map corresponding to the first area based on the instruction information. In other words, the instruction information triggers the PCF to execute step 202a.

[0131] As another implementation method, the PCF may also actively execute step 202a based on local policies.

[0132] In step 203a, the PCF determines whether to accept the requested QoS parameters based on the perception map and the requested QoS parameters.

[0133] For example, the PCF may determine whether to accept the requested QoS parameters based on the perception map and the location information of the UE.

[0134] In one implementation method, step 203a specifically includes: the PCF determines, based on the perception map, that a duration for which the requested QoS parameters cannot be met is less than or equal to a first duration, and then determines accepted QoS parameters, where the accepted QoS parameters are the same as the requested QoS parameters, or the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. For example, if the PCF determines that the UE's location is obscured by a dynamic moving object, which may cause temporary QoS degradation, the PCF may accept the requested QoS parameters or determine lower-level QoS parameters.

[0135] In another implementation method, step 203a specifically includes: the PCF determines, based on the perception map, that the duration for which the requested QoS parameters cannot be met is greater than a first duration, and then determines the accepted QoS parameters, where the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. For example, if the PCF determines that the UE's location is obscured by static objects or a large number / high density of objects, which may cause long-term QoS degradation, the PCF still determines the accepted QoS parameters, but the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. Optionally, the PCF also determines the retention time of the QoS level corresponding to the accepted QoS parameters.

[0136] In another implementation method, step 203a specifically includes: if the PCF determines, based on the perception map, that the requested QoS parameters cannot be met for a duration greater than a first duration, then the PCF rejects the requested QoS parameters. For example, if the PCF determines that the UE's location is obstructed by static objects or a large number or high density of objects, which may result in prolonged QoS degradation, then the PCF rejects the requested QoS parameters.

[0137] In another implementation method, step 203a specifically includes: if the PCF determines, based on the perception map, that the requested QoS parameters can be satisfied for a duration greater than a second duration, then the PCF accepts the requested QoS parameters, i.e., determines that the accepted QoS parameters are the same as the requested QoS parameters. For example, if the PCF determines that the UE's location is obstructed by a dynamic moving object, which may cause a temporary degradation in QoS, or that there is no obstruction, then the PCF may accept the requested QoS parameters.

[0138] In another implementation method, step 203a specifically includes: the PCF determines, based on the perception map, that the duration for which the requested QoS parameters can be satisfied is less than or equal to the second duration, and then the PCF determines the accepted QoS parameters, and the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. For example, if the PCF determines that the UE's location is obscured by static objects or a large number / high density of objects, which may cause long-term QoS degradation, the PCF still determines the accepted QoS parameters, but the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. Optionally, the PCF also determines the retention time of the QoS level corresponding to the accepted QoS parameters.

[0139] In another implementation method, step 203a specifically includes: if the PCF determines, based on the perception map, that the duration for which the requested QoS parameters can be met is less than or equal to a second duration, then the PCF rejects the requested QoS parameters. For example, if the PCF determines that the UE's location is obstructed by static objects or a large number or high density of objects, which may result in prolonged QoS degradation, then the PCF rejects the requested QoS parameters.

[0140] In another implementation method, step 203a specifically includes: the PCF determines the predicted QoS parameters based on the perception map; and determines whether to accept the requested QoS parameters based on the predicted QoS parameters and the requested QoS parameters. Exemplarily, the PCF determines the predicted QoS parameters based on the perception map, specifically including: the PCF determines the predicted QoS parameters corresponding to the first area based on the perception map; or, the PCF determines the predicted QoS parameters corresponding to the terminal device based on the perception map and the location information of the terminal device; or, the PCF determines the predicted QoS parameters corresponding to the terminal device based on the perception map, the location information of the terminal device and the identification information of the terminal device. Among them, there are multiple implementation methods for the PCF to determine whether to accept the requested QoS parameters based on the predicted QoS parameters and the requested QoS parameters. For detailed description, please refer to the introduction in step 206b of the embodiment of Figure 2(b), which will not be repeated here.

[0141] The above solution takes the information of the perception dimension as a consideration for UE communication control (such as QoS). That is, the PCF determines whether to accept the requested QoS parameters based on the perception map, which can optimize the communication QoS of the service and improve the service experience of communication.

[0142] It should be noted that in the embodiment shown in Figure 2(a) above, the PCF obtains the corresponding perception map after receiving the first request and determines whether to accept the requested QoS parameters based on the perception map. In another implementation, the PCF can also subscribe to the perception map corresponding to its service area from the SF in advance. The PCF can dynamically receive the latest perception map. Then, after receiving the first request, the PCF can directly determine whether to accept the requested QoS parameters based on the perception map. This can improve the efficiency of determining whether to accept the requested QoS parameters.

[0143] Figure 2(b) is a flow chart of a communication method provided in an embodiment of the present application. The method includes the following steps:

[0144] In step 201b, the PCF receives a first request, where the first request includes requested QoS parameters.

[0145] Specifically, the PCF may receive a first request from a UE, SMF, NEF, AF or other network elements.

[0146] As an implementation method, step 201b may also be replaced by: the PCF receives a first request, the first request includes indication information for indicating requested QoS parameters; the PCF obtains the requested QoS parameters according to the indication information.

[0147] The details of step 201b may refer to step 201a.

[0148] Step 202b: The PCF sends a QoS analysis request to the NWDAF. Correspondingly, the NWDAF receives the QoS analysis request.

[0149] The QoS analysis request includes a UE ID, location information of the UE, or information of a first area where the UE is located.

[0150] In one implementation method, the above-mentioned first request also includes a UE ID, then the QoS analysis request includes the UE ID; or, the PCF obtains the UE's location information from the AMF based on the UE ID, then the QoS analysis request includes the UE's location information; or, the PCF further determines the information of the first area where the UE is located based on the UE's location information, then the QoS analysis request includes the information of the first area.

[0151] In another implementation method, the above-mentioned first request also includes the UE's location information, then the QoS analysis request includes the UE's location information; or, the PCF determines the information of the first area where the UE is located based on the UE's location information, then the QoS analysis request includes the information of the first area.

[0152] In another implementation method, the above-mentioned first request also includes information about the first area where the UE is located, and the QoS analysis request includes information about the first area.

[0153] As an implementation method, the first request also includes indication information for indicating that communication should be optimized through network awareness. In this case, step 202b is specifically as follows: the PCF sends a QoS analysis request to the NWDAF according to the indication information. That is, the indication information triggers the PCF to execute step 202b.

[0154] In step 203b, the NWDAF obtains a perception map corresponding to the first area.

[0155] The perception map is state information of objects in the first area obtained through perception.

[0156] In one implementation method, if the QoS analysis request includes the UE ID, the NWDAF sends a location information request to the AMF, which includes the UE ID and is used to request the UE's location information. The AMF sends a location information response to the NWDAF, which carries the UE's location information. The NWDAF then determines information about the first area where the UE is located based on the UE's location information. The NWDAF then sends a perception map request to the SF, which includes information about the first area. The SF then sends a request message to the perception device, which includes information about the first area. The perception device sends a response message to the SF, which includes perception measurement data corresponding to the first area. The SF then generates a perception map based on the perception measurement data and sends a perception map response to the NWDAF, which includes the perception map.

[0157] In another implementation method, if the QoS analysis request includes the UE's location information, the NWDAF determines information about the first area where the UE is located based on the UE's location information. The NWDAF then sends a perception map request to the SF, where the perception map request includes information about the first area. The SF then sends a request message to the perception device, where the request message includes information about the first area. The perception device sends a response message to the SF, where the response message includes perception measurement data corresponding to the first area. The SF then generates a perception map based on the perception measurement data and sends a perception map response to the NWDAF, where the perception map response includes the perception map.

[0158] In another implementation method, if the above-mentioned QoS analysis request includes information of the first area, the NWDAF sends a perception map request to the SF, which includes information of the first area, and then the SF sends a request message to the perception device, which includes information of the first area, and the perception device sends a response message to the SF, which includes perception measurement data corresponding to the first area; then the SF generates a perception map based on the perception measurement data and sends a perception map response to the NWDAF, which includes the perception map.

[0159] In step 204b, the NWDAF determines predicted QoS parameters based on the perception map.

[0160] Since there are static objects and / or dynamic objects in the perception map, the predicted QoS parameters determined by NWDAF reflect the object occlusion at a certain location, or the object occlusion at a certain location and time, and then the corresponding QoS parameters, i.e., the predicted QoS parameters, can be determined.

[0161] Generally, if a location is blocked by a dynamic moving object, it may cause temporary QoS degradation. In this case, the QoS level corresponding to the predicted QoS parameters can be higher. If a location is blocked by a static object or a large number or high density of objects, it may cause long-term QoS degradation. In this case, the QoS level corresponding to the predicted QoS parameters can be lower.

[0162] As an implementation method, step 204b specifically includes: NWDAF determines the predicted QoS parameters corresponding to the first area based on the perception map.

[0163] As another implementation method, step 204b specifically includes: NWDAF determines the predicted QoS parameters corresponding to the terminal device based on the perception map and the location information of the terminal device.

[0164] As another implementation method, step 204b specifically includes: NWDAF determines the predicted QoS parameters corresponding to the terminal device based on the perception map, the location information of the terminal device and the identification information of the terminal device.

[0165] Step 205b: NWDAF sends a QoS analysis response to PCF. Correspondingly, PCF receives the QoS analysis response.

[0166] The QoS analysis response includes predicted QoS parameters.

[0167] In step 206b, the PCF determines whether to accept the requested QoS parameters based on the predicted QoS parameters and the requested QoS parameters.

[0168] Exemplarily, the PCF may determine whether to accept the requested QoS parameters based on the predicted QoS parameters and the location information of the UE.

[0169] In one implementation method, step 206b specifically includes: the PCF determines, based on the predicted QoS parameters, that the duration for which the requested QoS parameters cannot be met is less than or equal to a first duration, and then determines an accepted QoS parameter, where the accepted QoS parameter is the same as the requested QoS parameter, or the QoS level corresponding to the accepted QoS parameter is lower than the QoS level corresponding to the requested QoS parameter. For example, if the UE is located by a dynamic moving object, which may cause temporary QoS degradation, that is, the predicted QoS parameters cannot meet the requested QoS parameters but the duration is short, the PCF may accept the requested QoS parameters or determine a lower-level QoS parameter.

[0170] In another implementation method, step 206b specifically includes: the PCF determines, based on the predicted QoS parameters, that the requested QoS parameters cannot be met for a duration greater than a first duration, and then determines accepted QoS parameters, where the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. For example, if the UE's location is obscured by static objects or a large number / high density of objects, this may result in long-term QoS degradation, i.e., the predicted QoS parameters cannot meet the requested QoS parameters and the duration is long. In this case, the PCF still determines accepted QoS parameters, but the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. Optionally, the PCF also determines the retention time of the QoS level corresponding to the accepted QoS parameters.

[0171] In another implementation method, step 206b specifically includes: the PCF determines, based on the predicted QoS parameters, that the requested QoS parameters cannot be met for a duration greater than a first duration, and the PCF may reject the requested QoS parameters. For example, if the UE is located by obstruction from static objects or a large number or high density of objects, which may result in long-term QoS degradation, i.e., the predicted QoS parameters cannot meet the requested QoS parameters for a long duration, the requested QoS parameters may be rejected.

[0172] In another implementation method, step 206b specifically includes: if the PCF determines, based on the predicted QoS parameters, that the requested QoS parameters can be satisfied for a duration greater than a second duration, then the PCF accepts the requested QoS parameters, i.e., determines that the accepted QoS parameters are the same as the requested QoS parameters. For example, if the PCF determines that the UE's location is obstructed by a dynamic moving object, which may cause temporary QoS degradation, or that there is no obstruction, then the PCF may accept the requested QoS parameters.

[0173] In another implementation method, step 206b specifically includes: the PCF determines, based on the predicted QoS parameters, that the duration for which the requested QoS parameters can be satisfied is less than or equal to a second duration, and then the PCF determines accepted QoS parameters, where the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. For example, if the PCF determines that the UE's location is obscured by static objects or a large number / high density of objects, which may result in long-term QoS degradation, the PCF still determines accepted QoS parameters, but the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. Optionally, the PCF also determines the duration for which the QoS level corresponding to the accepted QoS parameters is maintained.

[0174] In another implementation method, step 206b specifically includes: if the PCF determines, based on the predicted QoS parameters, that the duration for which the requested QoS parameters can be satisfied is less than or equal to a second duration, then the PCF rejects the requested QoS parameters. For example, if the PCF determines that the UE's location is obstructed by static objects or a large number or high density of objects, which may result in prolonged QoS degradation, then the PCF rejects the requested QoS parameters.

[0175] The above solution takes the information of the perception dimension as a consideration for UE communication control (such as QoS). That is, the NWDAF determines the predicted QoS parameters based on the perception map and sends them to the PCF. The PCF then determines whether to accept the requested QoS parameters based on the predicted QoS parameters, which can optimize the communication QoS of the service and improve the service experience of communication.

[0176] It should be noted that in the embodiment shown in Figure 2(b) above, the NWDAF obtains the corresponding perception map after receiving a QoS analysis request from the PCF and determines the predicted QoS parameters based on the perception map. In another implementation, the NWDAF can also obtain information about the PCF's service area in advance and subscribe to the perception map corresponding to the PCF's service area from the SF. The NWDAF can dynamically receive the latest perception map and then, upon receiving a QoS analysis request, directly determine the predicted QoS parameters based on the perception map. This improves the efficiency of determining the predicted QoS parameters.

[0177] Figure 2(c) is a flow chart of a communication method provided in an embodiment of the present application. The method includes the following steps:

[0178] Step 201c: The PCF sends a QoS analysis request to the NWDAF. Correspondingly, the NWDAF receives the QoS analysis request.

[0179] The QoS analysis request includes requested QoS parameters and information about the first area where the UE is located.

[0180] In step 202c, the NWDAF obtains a perception map corresponding to the first area.

[0181] Specifically, the NWDAF sends a perception map request to the SF, which includes information about the first area. The SF then sends a request message to the perception device, which includes information about the first area. The perception device sends a response message to the SF, which includes perception measurement data corresponding to the first area. The SF then generates a perception map based on the perception measurement data and sends a perception map response to the NWDAF, which includes the perception map.

[0182] In step 203c, the NWDAF determines whether to accept the requested QoS parameters based on the perception map and the requested QoS parameters.

[0183] Exemplarily, the NWDAF may determine whether to accept the requested QoS parameters based on the perception map and the location information of the UE.

[0184] In one implementation method, step 203c specifically includes: the NWDAF determines, based on the perception map, that the duration for which the requested QoS parameters cannot be met is less than or equal to the first duration, and then determines accepted QoS parameters, where the accepted QoS parameters are the same as the requested QoS parameters, or the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. For example, if the PCF determines that the UE's location is obscured by a dynamic moving object, which may cause temporary QoS degradation, the PCF may accept the requested QoS parameters or determine lower-level QoS parameters.

[0185] In another implementation method, step 203c specifically includes: the NWDAF determines, based on the perception map, that the duration for which the requested QoS parameters cannot be met is greater than the first duration, and then determines the accepted QoS parameters, and the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. For example, if the NWDAF determines that the UE's location is obscured by static objects or a large number / high-density objects, which may cause long-term QoS degradation, the NWDAF still determines the accepted QoS parameters, but the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. Optionally, the NWDAF also determines the retention time of the QoS level corresponding to the accepted QoS parameters.

[0186] In another implementation method, step 203c specifically includes: if the NWDAF determines, based on the perception map, that the requested QoS parameters cannot be met for a duration greater than a first duration, then the NWDAF rejects the requested QoS parameters. For example, if the NWDAF determines that the UE's location is obstructed by static objects or a large number or high density of objects, which may result in long-term QoS degradation, then the NWDAF rejects the requested QoS parameters.

[0187] In another implementation method, step 203c specifically includes: if the NWDAF determines, based on the perception map, that the requested QoS parameters can be satisfied for a duration greater than a second duration, then the NWDAF accepts the requested QoS parameters, i.e., determines that the accepted QoS parameters are the same as the requested QoS parameters. For example, if the NWDAF determines that the UE's location is obstructed by a dynamic moving object, which may cause temporary QoS degradation, or if there is no obstruction, then the NWDAF may accept the requested QoS parameters.

[0188] In another implementation method, step 203c specifically includes: the NWDAF determines, based on the perception map, that the duration for which the requested QoS parameters can be satisfied is less than or equal to the second duration, and then the NWDAF determines the accepted QoS parameters, and the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. For example, if the NWDAF determines that the UE's location is obscured by static objects or a large number / high-density objects, which may cause long-term QoS degradation, the NWDAF still determines the accepted QoS parameters, but the QoS level corresponding to the accepted QoS parameters is lower than the QoS level corresponding to the requested QoS parameters. Optionally, the NWDAF also determines the retention time of the QoS level corresponding to the accepted QoS parameters.

[0189] In another implementation method, step 203c specifically includes: if the NWDAF determines, based on the perception map, that the duration for which the requested QoS parameters can be satisfied is less than or equal to the second duration, then the NWDAF rejects the requested QoS parameters. For example, if the NWDAF determines that the UE's location is obstructed by static objects or a large number or high density of objects, which may result in long-term QoS degradation, then the NWDAF rejects the requested QoS parameters.

[0190] In another implementation method, step 203c specifically includes: NWDAF determines the predicted QoS parameters based on the perception map; and determines whether to accept the requested QoS parameters based on the predicted QoS parameters and the requested QoS parameters. Exemplarily, NWDAF determines the predicted QoS parameters based on the perception map, specifically including: NWDAF determines the predicted QoS parameters corresponding to the first area based on the perception map; or, NWDAF determines the predicted QoS parameters corresponding to the terminal device based on the perception map and the location information of the terminal device; or, NWDAF determines the predicted QoS parameters corresponding to the terminal device based on the perception map, the location information of the terminal device and the identification information of the terminal device. Among them, there are multiple implementation methods for NWDAF to determine whether to accept the requested QoS parameters based on the predicted QoS parameters and the requested QoS parameters. For detailed description, please refer to the introduction in step 206b of the embodiment of Figure 2(b), which will not be repeated here.

[0191] In step 204c, the NWDAF sends a QoS analysis response to the PCF, and the PCF receives the QoS analysis response accordingly.

[0192] The QoS analysis response includes accepted QoS parameters, or the QoS analysis response is used to indicate rejection of requested QoS parameters.

[0193] The above solution uses information from the perception dimension as a consideration for communication control (such as QoS). That is, NWDAF determines whether to accept QoS parameters based on the perception map, thereby achieving more refined control of service quality, optimizing the communication QoS of the service, and improving the service experience of communication.

[0194] It should be noted that in the embodiment shown in Figure 2(c) above, the NWDAF obtains the corresponding perception map after receiving the QoS analysis request and determines whether to accept the requested QoS parameters based on the perception map. In another implementation, the NWDAF can also obtain information about the PCF's service area in advance and subscribe to the perception map corresponding to the PCF's service area from the SF. The NWDAF can dynamically receive the latest perception map. Then, after receiving a QoS analysis request, the NWDAF can directly determine whether to accept the requested QoS parameters based on the perception map. This can improve the efficiency of determining whether to accept the requested QoS parameters.

[0195] Figure 2(d) is a flow chart of a communication method provided in an embodiment of the present application. The method includes the following steps:

[0196] In step 201d, the NEF sends a QoS analysis request to the NWDAF, and the NWDAF receives the QoS analysis request.

[0197] The QoS analysis request includes information about the first area, and is used to request to obtain available QoS parameters corresponding to the first area. Optionally, the area may be range information, location information, or route track information.

[0198] Optionally, the QoS analysis request also includes time information, and the QoS analysis request is used to request to obtain the available QoS parameters corresponding to the time information and the first area.

[0199] As an implementation method, before step 201d, the AF sends a QoS request to the NEF, where the QoS request includes information about the first area and is used to request the acquisition of available QoS parameters corresponding to the first area. Alternatively, the QoS request includes information about the first area and time information, and is used to request the acquisition of available QoS parameters corresponding to the time information and the first area.

[0200] In step 202d, the NWDAF obtains a perception map corresponding to the first area.

[0201] The perception map is state information of objects in the first area obtained through perception.

[0202] Exemplarily, the NWDAF sends a perception map request to the SF, where the perception map request includes information about the first area. The SF then sends a request message to the perception device, where the request message includes information about the first area. The perception device sends a response message to the SF, where the response message includes perception measurement data corresponding to the first area. The SF then generates a perception map based on the perception measurement data and sends a perception map response to the NWDAF, where the perception map response includes the perception map.

[0203] In step 203d, the NWDAF determines the QoS parameters that can be provided based on the perception map.

[0204] The QoS parameters that can be provided are the QoS parameters that can be provided by the first area.

[0205] Optionally, the NWDAF generates available QoS parameters based on the perception map and time information, and the available QoS parameters are QoS parameters that can be provided by the first area within the time period indicated by the time information.

[0206] In step 204d, the NWDAF sends a QoS analysis response to the NEF, and the NEF receives the QoS analysis response.

[0207] The QoS analysis response includes available QoS parameters.

[0208] As an implementation method, after step 204d, the NEF sends a QoS response to the AF, where the QoS response includes the QoS parameters that can be provided.

[0209] The above solution uses information from the perception dimension as a consideration for communication control (such as QoS). That is, the NWDAF determines the available QoS parameters based on the perception map and sends them to the AF, achieving more refined control over service quality. This can optimize the communication QoS of the service and improve the service experience of communication.

[0210] It should be noted that in the embodiment shown in Figure 2(d) above, the NWDAF obtains the corresponding perception map after receiving the QoS analysis request and determines the available QoS parameters based on the perception map. In another implementation, the NWDAF can also obtain information about the PCF's service area in advance and subscribe to the perception map corresponding to the PCF's service area from the SF. The NWDAF can dynamically receive the latest perception map and then, upon receiving a QoS analysis request, directly determine the available QoS parameters based on the perception map. This improves the efficiency of determining available QoS parameters.

[0211] The following describes the embodiments of Figures 2(a) to 2(d) above in conjunction with the specific embodiments of Figures 3 to 6. The embodiment of Figure 3 is a specific example of the embodiment of Figure 2(a) above, the embodiment of Figure 4 is a specific example of the embodiment of Figure 2(b) above, the embodiment of Figure 5 is a specific example of the embodiment of Figure 2(c) above, and the embodiment of Figure 6 is a specific example of the embodiment of Figure 2(d) above.

[0212] FIG3 is a flow chart of a communication method provided in an embodiment of the present application. The method includes the following steps:

[0213] Step 301: The SMF receives a request message, where the request message is used to request the creation, modification, or deletion of a QoS flow.

[0214] Optionally, the request message may include data packet detection information (packFiltInfo), and may also include an identifier (pccRuleId) and / or QoS parameters of a policy and charging control (PCC) rule, and optionally, indication information, which is used to indicate communication optimization through network awareness.

[0215] In one implementation method, the SMF receives a request message, specifically including: the SMF receives a PDU_Session_Modification request from the UE; the request may include packet detection information, and may also include pccRuleId and / or QoS parameters; additionally, it may also include an alternative QoS configuration (alternative QoS profile), wherein the alternative QoS profile includes multiple QoS profiles, such as QoS profile1, QoS profile2, and QoS profile3, and each QoS profile includes parameters such as a guaranteed flow bit rate (GFBR), a packet delay budget (PDB), or a packet error rate (PER). The PDU_Session_Modification request is sent by the AMF to the SMF through the Nsmf_PDUSession_UpdateSMContext request.

[0216] In another implementation method, the SMF receives a request message, specifically including: the SMF receives a QoS flow modification request or deletion request from a base station; the request includes QoS flow identification information. The QoS flow modification request or deletion request is sent by the AMF to the SMF via an Nsmf_PDUSession_UpdateSMContext request.

[0217] In another implementation method, the SMF receives a request message, specifically including: the SMF receives an Npcf_SMPolicyControl_UpdateNotify request from the PCF. For example, the AF sends a request message to the PCF, where the request message is used to create, modify, or delete a QoS flow for a service request, and optionally includes the aforementioned indication information; based on the received request message, the PCF decides that an updated policy needs to be provided to the SMF, and then sends an Npcf_SMPolicyControl_UpdateNotify request to the SMF, where the request includes updated PCC policy information about the PDU session, and optionally includes the aforementioned indication information.

[0218] In step 302a, the SMF sends a location information request to the AMF. In response, the AMF receives the location information request.

[0219] The location information request is used to request to obtain the location information of the UE, and the request message includes the UE ID.

[0220] Step 302b: AMF sends a location information response to SMF. Correspondingly, SMF receives the location information response.

[0221] The location information response includes the location information of the UE, and the location information of the UE may be the ID of the cell currently accessed by the UE or specific location information obtained through UE positioning.

[0222] Step 302a and step 302b are optional steps.

[0223] Step 303: The SMF sends a policy update request to the PCF. Correspondingly, the PCF receives the policy update request.

[0224] The policy update request includes the UE ID and the requested QoS parameters. The requested QoS parameters may be provided by the UE or AF in step 301, or negotiated between the SMF and the UE or AF, or generated by the SMF based on an alternative QoS profile decision.

[0225] If the request message in step 301 carries indication information, the policy update request may also carry the indication information.

[0226] If the above steps 302a and 302b are performed, the policy update request may also carry the location information of the UE.

[0227] This policy update request is a specific example of the first request in the embodiment of FIG2(a).

[0228] Step 304: The PCF sends a perception map request to the SF. Correspondingly, the SF receives the perception map request.

[0229] If step 303 carries indication information, the PCF decides to send a perception map request to the SF based on the indication information.

[0230] If step 303 does not carry indication information, the PCF may independently decide that it needs to optimize communication through network awareness, and therefore send an awareness map request to the SF.

[0231] If the PCF receives the UE's location information in step 303, the PCF determines information about a first area where the UE is located based on the UE's location information. The first area may be the same as or different from the UE's location information, which is not limited in this application. The perception map request then includes information about the first area.

[0232] Alternatively, if the PCF receives the location information of the UE in step 303, the perception map request includes the location information of the UE.

[0233] If the PCF does not receive the UE's location information in step 303, the perception map request includes the UE ID.

[0234] Or if the PCF does not receive the UE's location information in step 303, the PCF may also obtain the UE's location information from the AMF based on the UE ID, and the perception map request includes the UE's location information or includes information about the first area determined by the PCF based on the UE's location information.

[0235] To summarize, the perception map request may carry at least one of the UE ID, the UE location information, or the information of the first area.

[0236] In step 305a, the SF sends a location information request to the AMF. In response, the AMF receives the location information request.

[0237] The location information request includes a UE ID, and the location information request is used to request obtaining the location information of the UE.

[0238] In step 305b, the AMF sends a location information response to the SF. In response, the SF receives the location information response.

[0239] The location information response includes the UE's location information, which may be the cell ID of the UE currently accessing or specific location information obtained through UE positioning. After receiving the UE's location information, the SF may determine information about the first area where the UE is located based on the UE's location information.

[0240] Steps 305a and 305b are optional. If the perception map request in step 304 carries information about the first area, steps 305a and 305b are not required. If the perception map request in step 304 carries the UE ID, steps 305a and 305b are required.

[0241] In step 306a, the SF sends a request message to the sensing device, and the sensing device receives the request message accordingly.

[0242] The request message includes information of the first area or location information of the UE, and the request message is used to request perception measurement data corresponding to the first area.

[0243] The sensing device may be integrated into the base station, that is, the sensing device is a functional module of the base station, or the sensing device may be an independent physical device, such as an independent terminal device.

[0244] Step 306b: The sensing device sends a response message to the SF, and the SF receives the response message accordingly.

[0245] The response message includes perception measurement data corresponding to the first area, where the perception measurement data indicates environmental information around the UE, such as one or more of the number of objects, object distribution, object type, object size, object outline, object movement speed, or object movement direction. The objects may be static or dynamic.

[0246] Among them, steps 306a and 306b are optional. Because before step 301, SF has controlled these perception devices to perform perception and continuously obtain perception measurement data, so SF can generate the required perception map based on these perception measurement data.

[0247] Step 307: SF generates a perception map based on the perception measurement data.

[0248] In step 308, the SF sends a perception map response to the PCF, and the PCF receives the perception map response accordingly.

[0249] The perception map response includes a perception map.

[0250] Optionally, if the perception map request in step 304 carries a UE ID, the perception map response further includes the location information of the UE.

[0251] In step 309, the PCF determines whether to accept the requested QoS parameters based on the perception map.

[0252] For example, the PCF may determine whether to accept the requested QoS parameters based on the perception map and the location information of the UE.

[0253] For a detailed implementation of step 309 , reference may be made to the description of step 203 a in the embodiment of FIG. 2 ( a ).

[0254] Step 310: PCF sends a policy update response to SMF. Correspondingly, SMF receives the policy update response.

[0255] The policy update response includes the accepted QoS parameters, or the policy update response is used to indicate rejection of the requested QoS parameters.

[0256] Exemplarily, the policy update response may be an Npcf_SMPolicyControl_Update response.

[0257] Step 311: The SMF executes the subsequent process of session modification according to the received QoS parameters.

[0258] This step 311 is an optional step. When the SMF receives the accepted QoS parameters, step 311 may be executed.

[0259] The above solution takes the information of the perception dimension as a consideration for UE communication control (such as QoS). That is, the PCF determines whether to accept the requested QoS parameters based on the perception map, which can optimize the communication QoS of the service and improve the service experience of communication.

[0260] FIG4 is a flow chart of a communication method provided in an embodiment of the present application. The method includes the following steps:

[0261] Step 401 is the same as step 301 in the embodiment of FIG. 3 .

[0262] Steps 402a to 402b are the same as steps 302a to 302b in the embodiment of FIG. 3 .

[0263] Step 403 is the same as step 303 in the embodiment of FIG. 3 .

[0264] Step 404: The PCF sends a QoS analysis request to the NWDAF. Correspondingly, the NWDAF receives the QoS analysis request.

[0265] If step 403 carries indication information, the PCF decides to send a QoS analysis request to the NWDAF based on the indication information. If step 403 does not carry indication information, the PCF can independently decide that communication needs to be optimized through network awareness, and thus send a QoS analysis request to the NWDAF.

[0266] In one implementation method, if the PCF receives the location information of the UE in step 403, the QoS analysis request includes the location information of the UE or includes information of the first area where the UE is located, and the information of the first area is determined by the PCF based on the location information of the UE.

[0267] In another implementation method, if the PCF does not receive the UE location information in step 403, the QoS analysis request includes the UE ID.

[0268] Or if the PCF does not receive the UE's location information in step 403, the PCF may also obtain the UE's location information from the AMF based on the UE ID, and the QoS analysis request includes the UE's location information or includes information of the first area determined by the PCF based on the UE's location information.

[0269] In summary, the QoS analysis request may carry at least one of the UE ID, the UE location information, or the information of the first area.

[0270] Exemplarily, the QoS analysis request may be a Nnwdaf_AnalyticsInfo request.

[0271] In step 405a, the NWDAF sends a location information request to the AMF. In response, the AMF receives the location information request.

[0272] The location information request is used to request to obtain the location information of the UE, and the location information request includes a UE ID.

[0273] In step 405b, the AMF sends a location information response to the NWDAF. In response, the NWDAF receives the location information response.

[0274] The location information response includes the location information of the UE, and the location information of the UE may be the ID of the cell currently accessed by the UE or specific location information obtained through UE positioning.

[0275] Steps 405a and 405b are optional. If the QoS analysis request in step 404 carries the UE's location information or information about the first area, then steps 405a and 405b are not required. If the QoS analysis request in step 404 carries the UE ID, then steps 405a and 405b are required.

[0276] Step 406: NWDAF sends a perception map request to SF. Correspondingly, SF receives the perception map request.

[0277] The perception map request includes information of the first area or location information of the UE. The information of the first area may be generated by the NWDAF according to the location information of the UE or received from the PCF.

[0278] Among them, if step 404 carries the UE ID, the NWDAF obtains the UE's location information through the above steps 405a to 405b, and carries the UE's location information in the perception map request, or the NWDAF determines the information of the first area where the UE is located based on the UE's location information and carries the information of the first area in the perception map request.

[0279] If step 404 carries the location information of the UE, the NWDAF carries the location information of the UE in the perception map request, or the NWDAF determines the information of the first area where the UE is located based on the location information of the UE and carries the information of the first area in the perception map request.

[0280] If step 404 carries the information of the first area, then the NWDAF carries the information of the first area in the perception map request.

[0281] In step 407a, the SF sends a request message to the sensing device, and the sensing device receives the request message accordingly.

[0282] The request message includes information of the first area or location information of the UE, and the request message is used to request perception measurement data corresponding to the first area.

[0283] The sensing device may be integrated into the base station, that is, the sensing device is a functional module of the base station, or the sensing device may be an independent physical device, such as an independent terminal device.

[0284] In step 407b, the sensing device sends a response message to the SF, and the SF receives the response message accordingly.

[0285] The response message includes perception measurement data corresponding to the first area, where the perception measurement data is used to indicate environmental information around the UE, such as one or more of the number of objects, object distribution, object type, object size, object outline, object movement speed, or object movement direction.

[0286] Among them, steps 407a and 407b are optional. Because before step 401, SF has controlled these perception devices to perform perception and continuously obtain perception measurement data, so SF can generate the required perception map based on these perception measurement data.

[0287] In step 408, the SF generates a perception map based on the perception measurement data.

[0288] Step 409: The SF sends a perception map response to the NWDAF. Correspondingly, the NWDAF receives the perception map response.

[0289] The perception map response includes a perception map.

[0290] In step 410, the NWDAF sends a QoS analysis response to the PCF. Correspondingly, the PCF receives the QoS analysis response.

[0291] The QoS analysis response includes predicted QoS parameters.

[0292] Since there are static objects and / or dynamic objects in the perception map, the predicted QoS parameters determined by NWDAF reflect the object occlusion situation at a certain location at a certain time, and then the corresponding QoS parameters, i.e., the predicted QoS parameters, can be determined.

[0293] Generally, if a location is blocked by a dynamic moving object, it may cause temporary QoS degradation. In this case, the QoS level corresponding to the predicted QoS parameters can be higher. If a location is blocked by a static object or a large number or high density of objects, it may cause long-term QoS degradation. In this case, the QoS level corresponding to the predicted QoS parameters can be lower.

[0294] Optionally, if the QoS analysis request in step 404 carries the UE ID, the QoS analysis response further includes the UE location information.

[0295] Exemplarily, the QoS analysis response may be a Nnwdaf_AnalyticsInfo response message.

[0296] In step 411, the PCF determines whether to accept the requested QoS parameters based on the predicted QoS parameters.

[0297] Exemplarily, the PCF may determine whether to accept the requested QoS parameters based on the predicted QoS parameters and the location information of the UE.

[0298] For a detailed implementation of step 411 , reference may be made to the description of step 206 b in the embodiment of FIG. 2( b ).

[0299] Steps 412 to 413 are the same as steps 310 to 311 in the embodiment of FIG. 3 .

[0300] The above solution takes the information of the perception dimension as a consideration for UE communication control (such as QoS). That is, the NWDAF determines the predicted QoS parameters based on the perception map and sends them to the PCF. The PCF then determines whether to accept the requested QoS parameters based on the predicted QoS parameters, which can optimize the communication QoS of the service and improve the service experience of communication.

[0301] FIG5 is a flow chart of a communication method provided in an embodiment of the present application. The method includes the following steps:

[0302] Step 501: The AF sends a QoS request to the NEF. Correspondingly, the NEF receives the QoS request.

[0303] The QoS request includes requested QoS parameters and information about the first zone. Optionally, it also includes indication information, where the indication information is used to indicate that communication should be optimized through network awareness.

[0304] Illustratively, the requested QoS parameters include a QoS reference (QoS Reference) or explicit QoS parameter content (individual QoS parameters), and optionally also include alternative service requirements (Alternative Service Requirements) of the requested QoS parameters.

[0305] Exemplarily, the QoS request may be a Nnef_AFsessionWithQoS_Create request or a Nnef_AFsessionWithQoS_Update request.

[0306] Step 502: NEF sends a policy request to PCF. Correspondingly, PCF receives the policy request.

[0307] The policy request includes requested QoS parameters and information of the first zone.

[0308] If the QoS request includes indication information, the policy request also includes the indication information.

[0309] Illustratively, the policy request is an Npcf_PolicyAuthorization_Create request or an Npcf_PolicyAuthorization_Update request.

[0310] Step 503: The PCF sends a QoS analysis request to the NWDAF. Correspondingly, the NWDAF receives the QoS analysis request.

[0311] If step 502 carries indication information, the PCF decides to send a QoS analysis request to the NWDAF based on the indication information. If step 502 does not carry indication information, the PCF can independently decide that communication needs to be optimized through network awareness, and thus send a QoS analysis request to the NWDAF.

[0312] The QoS analysis request includes requested QoS parameters and information of the first zone.

[0313] Exemplarily, the QoS analysis request may be a Nnwdaf_AnalyticsInfo request.

[0314] Step 504: NWDAF sends a perception map request to SF. Correspondingly, SF receives the perception map request.

[0315] The perception map request includes information of a first area.

[0316] In step 505a, the SF sends a request message to the sensing device, and the sensing device receives the request message accordingly.

[0317] The request message includes information about the first area, and the request message is used to request perception measurement data corresponding to the first area.

[0318] The sensing device may be integrated into the base station, that is, the sensing device is a functional module of the base station, or the sensing device may be an independent physical device, such as an independent terminal device.

[0319] Step 505b: The sensing device sends a response message to the SF, and the SF receives the response message accordingly.

[0320] The response message includes perception measurement data corresponding to the first area, where the perception measurement data indicates environmental information around the UE, such as one or more of the number of objects, object distribution, object type, object size, object outline, object movement speed, or object movement direction. The objects may be static or dynamic.

[0321] Among them, steps 505a and 505b are optional. Because before step 501, SF has controlled these perception devices to perform perception and continuously obtain perception measurement data, so SF can generate the required perception map based on these perception measurement data.

[0322] Step 506: SF generates a perception map based on the perception measurement data.

[0323] Step 507: SF sends a perception map response to NWDAF. Correspondingly, NWDAF receives the perception map response.

[0324] The perception map response includes a perception map.

[0325] In step 508, the NWDAF determines whether to accept the requested QoS parameters based on the perception map.

[0326] For a detailed implementation of step 508 , please refer to the description of step 203 a in the embodiment of FIG. 2 ( a ).

[0327] In step 509, the NWDAF sends a QoS analysis response to the PCF. Correspondingly, the PCF receives the QoS analysis response.

[0328] The QoS analysis response includes accepted QoS parameters, or the QoS analysis response is used to indicate rejection of requested QoS parameters.

[0329] Step 510: The PCF sends a policy response to the NEF. Correspondingly, the NEF receives the policy response.

[0330] The policy response includes the accepted QoS parameters, or the policy response is used to indicate a rejection of the requested QoS parameters.

[0331] Illustratively, the policy response is an Npcf_PolicyAuthorization_Create response.

[0332] Step 511: NEF sends a QoS response to AF. Correspondingly, AF receives the QoS response.

[0333] The QoS response includes accepted QoS parameters, or the QoS response is used to indicate rejection of requested QoS parameters.

[0334] Exemplarily, the QoS response may be a Nnef_AFsessionWithQoS_Create response.

[0335] The above solution uses information from the perception dimension as a consideration for communication control (such as QoS). That is, NWDAF determines whether to accept QoS parameters based on the perception map, thereby achieving more refined control of service quality, optimizing the communication QoS of the service, and improving the service experience of communication.

[0336] FIG6 is a flow chart of a communication method provided in an embodiment of the present application. The method includes the following steps:

[0337] Step 601: The AF sends a QoS request to the NEF. Correspondingly, the NEF receives the QoS request.

[0338] The QoS request includes information about the first area, and is used to request to obtain available QoS parameters corresponding to the first area.

[0339] Optionally, the QoS request also includes time information, and the QoS request is used to request to obtain the available QoS parameters corresponding to the time information and the first area.

[0340] Optionally, the QoS request also includes indication information, where the indication information is used to indicate that communication is optimized through network awareness.

[0341] Exemplarily, the QoS request may be a Nnef_AnalyticsExposure_Subscribe request.

[0342] Step 602: NEF sends a QoS analysis request to NWDAF. Correspondingly, NWDAF receives the QoS analysis request.

[0343] The QoS analysis request includes information about the first area, and optionally, also includes time information.

[0344] If the QoS request includes indication information, the QoS analysis request also includes the indication information.

[0345] Exemplarily, the QoS analysis request is a Nnwdaf_AnalyticsInfo request.

[0346] Step 603: NWDAF sends a perception map request to SF. Correspondingly, SF receives the perception map request.

[0347] The perception map request includes information of a first area.

[0348] If step 602 carries the indication information, the NWDAF decides to send the perception map request to the SF based on the indication information. If step 602 does not carry the indication information, the NWDAF can independently decide that communication needs to be optimized through network perception, and thus send the perception map request to the SF.

[0349] In step 604a, the SF sends a request message to the sensing device, and the sensing device receives the request message accordingly.

[0350] The request message includes information about the first area, and the request message is used to request perception measurement data corresponding to the first area.

[0351] The sensing device may be integrated into the base station, that is, the sensing device is a functional module of the base station, or the sensing device may be an independent physical device, such as an independent terminal device.

[0352] Step 604b: The sensing device sends a response message to the SF, and the SF receives the response message accordingly.

[0353] The response message includes perception measurement data indicating environmental information around the UE, such as one or more of the number of objects, object distribution, object type, object size, object outline, object movement speed, or object movement direction. These objects may be static or dynamic.

[0354] Among them, steps 604a and 604b are optional. Because before step 601, SF has controlled these perception devices to perform perception and continuously obtain perception measurement data, so SF can generate the required perception map based on these perception measurement data.

[0355] Step 605: SF generates a perception map based on the perception measurement data.

[0356] Step 606: The SF sends a perception map response to the NWDAF. Correspondingly, the NWDAF receives the perception map response.

[0357] The perception map response includes a perception map.

[0358] Step 607: NWDAF generates available QoS parameters based on the perception map.

[0359] The QoS parameters that can be provided are the QoS parameters that can be provided by the first area.

[0360] Optionally, the NWDAF generates available QoS parameters based on the perception map and time information, and the available QoS parameters are QoS parameters that can be provided by the first area within the time period indicated by the time information.

[0361] Step 608: NWDAF sends a QoS analysis response to NEF. Correspondingly, NEF receives the QoS analysis response.

[0362] The QoS analysis response includes available QoS parameters.

[0363] Exemplarily, the QoS analysis response is an Nnwdaf_AnalyticsInfo response.
