[0029] The technical solution of the present application will be described below in conjunction with the accompanying drawings. In order to facilitate understanding of the present application, the following first introduces the architecture applicable to the embodiment of the present application in conjunction with Figures 1 and 2.

[0030] Figures 1 and 2 are schematic diagrams of wireless communication systems applicable to embodiments of the present application. As shown in Figures 1 and 2, the fifth generation (5G) system or new radio (NR) network architecture released by the 3rd Generation Partnership Project (3GPP) standards group includes: a terminal device (also known as "user equipment (UE)" 101, an access network device 102 supporting 3GPP technology (including a radio access network (RAN) or access network (AN)), a user plane function (UPF) network element 105, an access and mobility management function (AMF) network element 103, a session management function (SMF) network element 104, a policy control function (PCF) network element 106, an application function (AF) network element 109, and a data network (DN) 108.

[0031] It should be noted that Figures 1 and 2 only show some network elements by way of example. In some scenarios, the above-mentioned wireless communication system may also include a network slice selection function (NSSF), an authentication service function (AUSF), a unified data management function (UDM), etc.

[0032] In addition, the network architecture shown in Figure 1 does not constitute a limitation on the 5G network architecture. In specific implementations, the 5G network architecture may include more or fewer network elements than shown, or combine certain network elements, etc. In addition, in Figure 1, AN or RAN is represented in the form of (R)AN.

[0033] The terminal device 101 can be user equipment (UE), a terminal, a handheld terminal, a laptop computer, a subscriber unit, a cellular phone, a smart phone, a wireless data card, a personal digital assistant (PDA) computer, a tablet computer, a wireless modem, a handheld device (handheld), a laptop computer, a cordless phone or a wireless local loop (WLL) station, a machine type communication (MTC) terminal, a handheld device with wireless communication function, a computing device, a processing device connected to a wireless modem, a drone, a vehicle-mounted device, a wearable device, a terminal in the Internet of Things, a virtual reality device, a terminal device in a future communication system (e.g., 6G) network, a terminal in a future evolved public land mobile network (PLMN), etc.

[0034] The access network device 102 is an access device that connects terminal devices to the network architecture wirelessly. It is primarily responsible for radio resource management, quality of service (QoS) management, data compression and encryption, etc. on the air interface side. Examples include NodeBs, evolved eNodeBs, base stations in 5G mobile communication systems or new radio (NR) communication systems, and base stations in future mobile communication systems.

[0035] UPF network element 105, AMF network element 103, SMF network element 104, and PCF network element 106 are network elements of the 3GPP core network (referred to as core network elements). UPF network element 105 can be called a user plane function network element, which is mainly responsible for the transmission of user data. The other network elements can be called control plane function network elements, which are mainly responsible for authentication, authorization, registration management, session management, mobility management, and policy control to ensure reliable and stable transmission of user data.

[0036] The UPF network element 105 (or simply "UPF") can be used to forward and receive data from the terminal. For example, the UPF network element can receive service data from the data network and transmit it to the terminal through the access network equipment. The UPF network element can also receive user data from the terminal through the access network equipment and forward it to the data network. The transmission resources allocated and scheduled by the UPF network element for the terminal are managed and controlled by the SMF network element. The bearer between the terminal and the UPF network element may include: a user plane connection between the UPF network element and the access network equipment, and a channel established between the access network equipment and the terminal. The user plane connection is a QoS flow that can be established between the UPF network element and the access network equipment to transmit data.

[0037] The AMF network element 103 (or "AMF" for short) can be used to manage terminal access to the core network, such as terminal location update, network registration, access control, terminal mobility management, terminal attachment and detachment, etc. The AMF network element can also provide control plane storage resources for the session when providing services for the terminal session to store the session identifier, the SMF network element identifier associated with the session identifier, etc.

[0038] The SMF network element 104 (or "SMF" for short) can be used to select a user plane network element for the terminal, redirect the user plane network element for the terminal, allocate an Internet Protocol (IP) address to the terminal, establish a bearer (also called a session) between the terminal and the UPF network element, modify and release the session, and control QoS.

[0039] The PCF network element 106 (or simply "PCF") is used to provide policies, such as QoS policies, slice selection policies, etc., to the AMF network element 103 and the SMF network element 104.

[0040] The AF network element 109 (or simply "AF") is used to interact with the 3GPP core network elements to support application-affected data routing, access network exposure functions, and interact with the PCF network elements for policy control.

[0041] DN 108 can provide data services to users on networks such as IP Multimedia Service (IMS) and the Internet. DN 108 can contain multiple application servers (ASs) that provide different application services, such as carrier services, Internet access, or third-party services. ASs can implement the functions of AF network elements.

[0042] NSSF is used for network slice selection and supports the following functions: selecting the set of network slice instances serving the UE; determining the allowed network slice selection assistance information (NSSAI) and, when necessary, determining the mapping to the contracted single-network slice selection assistance information (S-NSSAI); determining the configured NSSAI and, when necessary, determining the mapping to the contracted S-NSSAI; determining the set of AMFs that may be used to query the UE, or determining a list of candidate AMFs based on the configuration.

[0043] AUSF is used to receive the request from AMF 103 to authenticate the terminal, request the key from UDM 107, and then forward the issued key to AMF 103 for authentication processing.

[0044] UDM includes functions such as the generation and storage of user contract data, management of authentication data, and supports interaction with external third-party servers.

[0045] It should be understood that each network element in Figure 1 and Figure 2 can be a network element in a hardware device, a software function running on dedicated hardware, or a virtualized function instantiated on a platform (for example, a cloud platform). It should be noted that the network architecture shown in the above figure is only an example of the network elements included in the entire network architecture. In the embodiments of the present application, the network elements included in the entire network architecture are not limited. In addition, in the embodiments of the present application, "network element" and device can be interchangeable. For example, the above-mentioned core network network element can also be referred to as a core network device.

[0046] As shown in Figure 1, each network element is connected to each other through a predetermined interface, that is, the network element interface mode is used for interaction. Among them, the interfaces between network elements may include, for example, N1 to N7 interfaces, N9 interface, N11 interface, N14 to N15 interfaces, and Uu interface.

[0047] Taking the UE as an example, the UE can establish an access stratum (AS) connection with the AN through the Uu interface, exchanging AS messages and wireless data transmission. In addition, the UE establishes a non-access stratum (NAS) connection with the AMF through the N1 interface, exchanging NAS messages.

[0048] Taking UPF as an example, UPF transmits data with DN through N6 interface. In addition, UPF can transmit data with AN through N3 interface.

[0049] 2, network elements interact by calling services provided by the network elements, that is, using the network element provided service mode for interaction. It should be understood that the embodiment of the present application does not limit the interaction mode between network elements, that is, network elements can use an interface mode or a service call mode.

[0050] In some communications systems, network management systems can monitor the energy consumption of network devices (also known as "network energy consumption"), thereby understanding the energy consumption of individual devices across the communications network and implementing network-level energy consumption control. For example, during idle periods, the network management system can shut down some network devices to reduce energy consumption and improve energy utilization. Currently, network management systems control network energy consumption at the granularity of network devices. In other words, network energy consumption control by network management systems typically involves shutting down entire network devices. Therefore, network energy consumption control at the granularity of network devices is also called network device-level energy consumption control. This type of network device-level energy consumption control has a coarse granularity and can reduce the user experience.

[0051] For example, in order to reduce network energy consumption, the network management device shuts down an access network device. Accordingly, all services of all terminal devices served by (or prepared to provide) the access network device will be suspended. For some services with high QoS requirements, the QoS requirements will not be met, resulting in a reduced user experience.

[0052] For example, in order to reduce network energy consumption, the network management device shuts down a core network device. Accordingly, all services of all terminal devices served by (or prepared to provide) the core network device will be suspended. For some services with high QoS requirements, the QoS requirements will not be met, resulting in a reduced user experience.

[0053] Therefore, to address the above issues, embodiments of the present application provide a network energy consumption control solution. This solution allows network energy consumption to be controlled at the granularity of terminal devices and / or QoS flows. Compared to traditional network device-level network energy consumption control, this solution helps reduce the probability of failing to meet QoS requirements and improves the user experience.

[0054] It should be noted that the aforementioned network energy consumption control based on QoS flows can be replaced with network energy consumption control based on service data flows. This is because, for different network devices, QoS flows are represented by service data flows. For example, for PCF, service data flows have not yet been mapped to QoS flows. In this case, network energy consumption control based on QoS flows is equivalent to network energy consumption control based on service data flows.

[0055] However, in the process of controlling network energy consumption with terminal devices and / or QoS flows as the control granularity, it is impossible to know which terminal devices and / or QoS flows' network energy consumption can be controlled and which terminal devices and / or QoS flows' network energy consumption cannot be controlled, resulting in unreasonable control of network energy consumption and inability to effectively improve user experience.

[0056] Therefore, in response to the above problems, an embodiment of the present application provides a method for wireless communication. In this method, communication devices can indicate whether a communication service based on network energy consumption control (also known as a "first communication service") and / or a first energy consumption mode of the first communication service are supported by exchanging first information. Compared with traditional network energy consumption control schemes, it is impossible to know which terminal devices and / or QoS flows have their network energy consumption controlled and which terminal devices and / or QoS flows cannot have their network energy consumption controlled, which helps to improve the rationality of network energy consumption control and thus improve user experience.

[0057] In an embodiment of the present application, the above-mentioned communication equipment may include one or more of the following: a first core network device, a second core network device, an access network device, a terminal device, and an AF. The first core network device may be, for example, an SMF, or other network device with similar functions to an SMF. The first core network device may be, for example, an AMF, or other network device with similar functions to an AMF. The second core network device may be, for example, a PCF, or other network device with similar functions to a PCF.

[0058] The following describes a wireless communication method according to an embodiment of the present application in conjunction with FIG3 . FIG3 is a schematic flow chart of the wireless communication method according to an embodiment of the present application. The method shown in FIG3 includes step S310 .

[0059] In step S310, the first core network device receives or sends first information.

[0060] In some implementations, the first information indicates whether a first communication service is supported, where the first communication service is based on network energy consumption control. In other words, the first information indicates whether the first communication service based on network energy consumption control is supported, or alternatively, indicates whether the network device agrees to consider network energy consumption when providing the communication service. Therefore, the first information can also be referred to as an "energy efficiency indicator."

[0061] In the embodiments of the present application, the implementation method of the first information is not specifically limited. For example, the first information may occupy one bit. If the value of the bit is a first value, it indicates that the first communication service based on network energy consumption control is supported. If the value of the bit is a second value, it indicates that the first communication service based on network energy consumption control is not supported. The first value and the second value are different values. For example, the first value may be 0 and the second value may be 1. For another example, the first value may be 0 and the second value may be 1.

[0062] In some other implementations, the first information is used to indicate a first energy consumption mode for controlling the first communication service, wherein the first energy consumption mode is used to indicate the importance between network energy consumption control and communication performance.

[0063] In some implementations, the first energy consumption mode may include one or more of the following: a communication mode in which network energy consumption is more important than communication performance; a communication mode in which network energy consumption and communication performance are balanced; and a communication mode in which network energy consumption is saved.

[0064] If the first energy consumption mode includes a communication mode in which the importance of network energy consumption is higher than the importance of communication performance, it can be understood that the first energy consumption mode indicates that the importance of communication performance is higher than the importance of network energy consumption control between network energy consumption and communication performance. Therefore, this energy consumption mode can also be called a "performance priority mode."

[0065] It should be noted that network energy consumption may not be considered in this communication mode, or network energy consumption may be considered less in this communication mode, which is not limited in the embodiments of the present application.

[0066] If the first energy consumption mode includes a communication mode that balances network energy consumption and communication performance, it can be understood that the first energy consumption mode indicates that the importance of communication performance is equivalent to the importance of network energy consumption control between network energy consumption and communication performance. Therefore, this energy consumption mode can also be called a "mode that balances energy consumption and performance."

[0067] If the first energy consumption mode includes a communication mode that balances network energy consumption and communication performance, it can be understood that the first energy consumption mode indicates that the importance of communication performance is lower than the importance of network energy consumption control between network energy consumption and communication performance. Therefore, this energy consumption mode can also be called an "energy consumption priority mode."

[0068] It should be noted that the above-mentioned one or more energy consumption modes may be determined based on one or more of the following: predefined information; configuration information of the network device; pre-configured information.

[0069] In an embodiment of the present application, the first information indicating whether the first communication service is supported and the first information indicating the first energy consumption mode for controlling the first communication service may be independent of each other, or in other words, information transmitted independently of each other. Of course, in an embodiment of the present application, the above two types of first information may also be used in combination with each other. For example, if the first information indicates the first energy consumption mode for controlling the first communication service, it may implicitly indicate support for the first communication service. At this time, in order to save the overhead of transmitting the first information, the first information may not specifically indicate whether the first communication service is supported through an additional bit.

[0070] In this embodiment of the present application, the energy consumption control granularity associated with the first information is not limited. In some implementations, the first information is associated with a terminal device. In this case, the first information is used to indicate whether the terminal device supports a first communication service; and / or to indicate a first energy consumption mode for controlling the first communication service. In other words, in this embodiment of the present application, the energy consumption control granularity of the network energy consumption can be based on the terminal device.

[0071] In other implementations, the first information is associated with a service data flow. In this case, the first information is used to indicate whether the service data flow supports a first communication service and / or to indicate a first energy consumption mode for controlling the first communication service. In other words, in this embodiment of the present application, the granularity of energy consumption control of network energy consumption can be based on the service data flow.

[0072] Of course, in the embodiment of the present application, the above-mentioned first information can also be associated with the network device. In this case, the energy consumption control granularity of the network energy consumption can be based on the network device as the control granularity.

[0073] The above introduces the first information in the embodiment of the present application, and the following introduces the scheme for transmitting the first information in the embodiment of the present application.

[0074] In some implementations, the first information may be sent by the terminal device to the first core network device. That is, the above step S310 may include: the first core network device receives the first information sent by the terminal device.

[0075] In some implementations, the first information is carried in a NAS message. The NAS message may include a first request message, wherein the first request message includes one or more of the following: a request message for requesting registration of a terminal device; a request message for requesting establishment of a protocol data unit (PDU) session; and a request message for requesting modification of a PDU session.

[0076] In some implementations, if the first information is carried in a request message for registering a terminal device (also referred to as a "registration request"), the control granularity associated with the first information may be the terminal device being registered in the registration request. In other words, the first information carried in the registration request is used to indicate whether the terminal device supports the first communication service and / or to indicate a first energy consumption mode for controlling the first communication service of the terminal device.

[0077] In other implementations, if the first information is carried in a request message for establishing a PDU session (also referred to as a "PDU session establishment request"), the control granularity associated with the first information may be a service data flow in the PDU session. In other words, the first information carried in the PDU session establishment request is used to indicate whether the service data flow supports the first communication service; and / or to indicate a first energy consumption mode for the first communication service associated with the control service data flow.

[0078] In the embodiments of the present application, the information indicating the service data flow is not limited. In some implementations, the PDU session establishment request may carry information indicating the service data flow. For example, the information indicating the service data flow may be a filter for the service data flow. For another example, the information indicating the service data flow may be an application identifier for the service data flow. For another example, the information indicating the service data flow may be a service identifier for the service data flow.

[0079] In other implementations, if the first information is carried in a request message for modifying a PDU session (also referred to as a "PDU session modification request"), the control granularity associated with the first information may be a service data flow within the PDU session. In other words, the first information carried in the PDU session modification request is used to indicate whether the service data flow supports a first communication service and / or to indicate a first energy consumption mode for the first communication service associated with the control service data flow.

[0080] In the embodiments of the present application, the information indicating the service data flow is not limited. In some implementations, the PDU session modification request may carry information indicating the service data flow. For example, the information indicating the service data flow may be a filter for the service data flow. In another example, the information indicating the service data flow may be an application identifier for the service data flow. In another example, the information indicating the service data flow may be a service identifier for the service data flow.

[0081] In some scenarios, the first core network device may send the first information to the second core network device for authorization. That is, the first information is authorized information. Step S310 includes: the first core network device sending a second request to the second core network device, the second request being for requesting authorization of the unauthorized first information; and the method further includes: the first core network device receiving a response message sent by the second core network device, the response message carrying the first information.

[0082] It should be noted that, as described above, the first core network device may send the first information to the second core network device for authorization. Of course, in this embodiment of the application, the first core network device may not send the first information to the second core network device for authorization.

[0083] In some implementations, the first core network device may send the first information to the access network device so that the access network device controls network energy consumption based on the first information. That is, the above step S310 includes: the first core network device sends the first information to the access network device.

[0084] In the embodiments of the present application, the access network device's control method for network energy consumption is not limited. In some implementations, if the first information indicates a first energy consumption mode and the first information is associated with a terminal device, the access network device may schedule wireless resources for the terminal device based on the first energy consumption mode. For example, if the first energy consumption mode indicates saving network energy consumption, the access network device may delay sending data to the terminal device during periods of high network energy consumption, thereby reducing network energy consumption.

[0085] In other implementations, if the first information indicates support for the first communication service and the first information is associated with the terminal device, the access network device may schedule wireless resources for the terminal device based on network energy consumption. For example, if the first information indicates support for the first communication service, the access network device may delay sending data to the terminal device during periods of high network energy consumption, thereby reducing network energy consumption.

[0086] It should be noted that network energy consumption can be determined based on one or more of the following: energy consumption of access network equipment; energy consumption of access network equipment providing transmission services to terminal devices; and energy consumption of terminal devices. This embodiment of the present application is not limited to this. Specifically, the energy consumption of terminal devices can be determined based on wireless signal quality. Generally, the worse the wireless signal quality, the higher the energy consumption of the terminal device. Conversely, the better the wireless signal quality, the lower the energy consumption of the terminal device.

[0087] In some implementations, if the first information indicates a first energy consumption mode and is associated with a QoS flow, the access network device may schedule radio resources for the QoS flow based on the first energy consumption mode. For example, if the first energy consumption mode indicates saving network energy consumption, the access network device may delay sending data for the QoS flow when network energy consumption is high, thereby reducing network energy consumption.

[0088] In other implementations, if the first information indicates support for the first communication service and the first information is associated with a QoS flow, the access network device may schedule radio resources for the terminal device based on network energy consumption. For example, if the first information indicates support for the first communication service, the access network device may delay sending data for the QoS flow when network energy consumption is high, thereby reducing network energy consumption.

[0089] It should be noted that the network energy consumption may be determined based on one or more of the following: energy consumption of the access network device; energy consumption of the access network device providing transmission services for the QoS flow; and energy consumption of the terminal device associated with the QoS flow. This embodiment of the application is not limited to this.

[0090] In addition, in the embodiments of the present application, the above description uses delayed data transmission as an example to describe methods for controlling network energy consumption, but the embodiments of the present application are not limited to this. In some implementations, the access network device can control network energy consumption by adjusting other QoS parameters. For example, the access network device can reduce network energy consumption by increasing the bit error rate of the QoS flow. For another example, the access network device can reduce network energy consumption by increasing the bit error rate of the terminal device.

[0091] In an embodiment of the present application, the first information may be the first information authorized by the second core network device. Of course, in a scenario where the first core network device does not send the first information to the second core network device for authorization, the first information may also be the first information not authorized by the second core network device. In this case, the first core network device may forward the first information sent by the terminal device to the access network device.

[0092] In some implementations, the first information sent by the first core network device to the access network device may be carried in a third request message, wherein the third request message includes one or more of the following: a request message for requesting to establish terminal device context information; a request message for requesting to modify terminal device context information; a request message for requesting to establish a QoS flow; a request message for requesting to modify a QoS flow.

[0093] In some implementations, if the first information is carried in a request message for establishing terminal device context information (also known as a "UE context establishment request"), the control granularity associated with the first information may be the terminal device associated with the UE context establishment request. In other words, the first information carried in the UE context establishment request is used to indicate whether the terminal device supports the first communication service; and / or to indicate a first energy consumption mode for controlling the first communication service of the terminal device.

[0094] In other implementations, if the first information is carried in a request message for modifying terminal device context information (also known as a "UE context modification request"), the control granularity associated with the first information may be the terminal device associated with the UE context modification request. In other words, the first information carried in the UE context modification request is used to indicate whether the terminal device supports the first communication service; and / or to indicate a first energy consumption mode for controlling the first communication service of the terminal device.

[0095] In other implementations, if the first information is carried in a request message for establishing a QoS flow (also referred to as a "QoS flow establishment request"), the control granularity associated with the first information may be the QoS flow associated with the QoS flow establishment request. In other words, the first information carried in the QoS flow establishment request is used to indicate whether the service data flow supports the first communication service; and / or to indicate a first energy consumption mode for the first communication service associated with the control service data flow.

[0096] In other implementations, if the first information is carried in a request message for modifying a QoS flow (also referred to as a "QoS flow modification request"), the control granularity associated with the first information may be the QoS flow associated with the QoS flow modification request. In other words, the first information carried in the QoS flow modification request is used to indicate whether the service data flow supports the first communication service; and / or to indicate a first energy consumption mode for the first communication service associated with the control service data flow.

[0097] For ease of understanding, the following describes a scheme in which the terminal device sends the first information in an embodiment of the present application in combination with Example 1 and Example 2.

[0098] In Example 1, it is assumed that the first information is associated with the terminal device. Figure 4 is a schematic flow chart of a transmission scheme for the first information in an embodiment of the present application. The method shown in Figure 4 includes steps S410 to S450.

[0099] In step S410, the terminal device sends a first request message to the first core network device, where the first request message carries first information.

[0100] In some implementations, the first request message may include a registration request. For details, please refer to the above introduction about the first request.

[0101] In step S420, the first core network device sends a second request message to the second core network device to request authorization for the first information.

[0102] In step S430, the second core network device sends the authorized first information to the first core network device.

[0103] In step S440, the first core network device sends a third request message to the access network device, where the third request message carries the authorized first information.

[0104] In some implementations, the third request message may include a UE context establishment request or a UE context modification request, that is, the terminal device identifier in the third request is transmitted to the access network device together with the first information to indicate whether the terminal device indicated by the terminal device identifier supports the first communication service, and / or controls the first energy consumption mode of the first communication service of the terminal device.

[0105] In step S450, the access network device schedules the wireless resources of the terminal device based on the first information.

[0106] In some implementations, the access network device schedules the wireless resources of the terminal device based on network energy consumption. For example, when network energy consumption is high, data transmission to the terminal device may be delayed, thereby reducing access network device energy consumption while not impacting service transmissions of other terminal devices. High network energy consumption may include one or more of the following: high access network device energy consumption, high terminal device energy consumption, or high energy consumption in providing transmission services to the terminal device.

[0107] In Embodiment 2, it is assumed that the first information is associated with a QoS flow. FIG5 is a schematic flow chart of a transmission scheme for the first information in another embodiment of the present application. The method shown in FIG5 includes steps S510 to S550.

[0108] In step S510, the terminal device sends a first request message to the first core network device, where the first request message carries first information.

[0109] In some implementations, the first request message may include a PDU session establishment request or a PDU session modification request. For details, please refer to the above introduction to the first request.

[0110] In step S520, the first core network device sends a second request message to the second core network device to request authorization for the first information.

[0111] In step S530, the second core network device sends the authorized first information to the first core network device.

[0112] In step S540, the first core network device sends a third request message to the access network device, where the third request message carries the authorized first information.

[0113] In some implementations, the third request message may include a QoS flow establishment request or a QoS flow modification request, that is, the QoS identifier in the third request is transmitted to the access network device together with the first information to indicate whether the QoS flow indicated by the QoS identifier supports the first communication service, and / or controls the first energy consumption mode of the first communication service associated with the QoS flow.

[0114] In step S550, the access network device schedules radio resources of the QoS flow based on the first information.

[0115] In some implementations, the access network device schedules the radio resources for the QoS flow based on network energy consumption. For example, when network energy consumption is high, data transmission for the QoS flow is delayed, thereby reducing access network device energy consumption without affecting the service transmission of other QoS flows. High network energy consumption can include one or more of the following: high access network device energy consumption, high terminal device energy consumption, and high energy consumption in providing transmission services for the terminal device's QoS flow.

[0116] The above describes, in conjunction with Example 1 and Example 2, the scheme for a terminal device to send first information in the embodiments of the present application. In some scenarios, the first information may be sent by the AF, in which case the first information may be associated with a service data flow. In some implementations, when the AF sends the first information, it may also carry information indicating the service data flow associated with the first information.

[0117] In the embodiments of the present application, the indication information of the service data flow is not limited. For example, the indication information of the service data flow may be a filter of the service data flow. For another example, the indication information of the service data flow may be an application identifier of the service data flow. For another example, the indication information of the service data flow may be a service identifier of the service data flow.

[0118] In some implementations, the AF may send the first information to the first core network device via the second core network device. That is, the above step S310 includes: the first core network device receives the first information sent by the second core network device.

[0119] In some implementations, the first information received by the first core network device from the second core network device may be information authorized by the second core network device. Of course, in this embodiment of the present application, the second core network device may not authorize the first information and directly forward it to the first core network device.

[0120] In some implementations, when the second core network device sends the first information to the first core network device, it may also indicate indication information of the service data flow associated with the first information, wherein the indication information of the service data flow can be referred to the above introduction.

[0121] In some implementations, after receiving the first information, the first core network device may map the service data flow associated with the first information to a QoS flow. In this case, the first information associated with the service data flow is transformed into first information associated with the QoS flow. In other words, the above method further includes: the first core network device determining the QoS flow associated with the service data flow; and the first core network device associating the first information with the QoS flow.

[0122] In some implementations, the first core network device may send first information associated with the QoS flow to the access network device, that is, the above step S310 includes: the first core network device sends first information to the access network device, wherein the first information is associated with the QoS flow.

[0123] In some implementations, the first information sent by the first core network device to the access network device may be carried in a third request message. The third request message includes one or more of the following: a request message for requesting to establish a QoS flow; or a request message for requesting to modify a QoS flow. The third request message is described above and will not be further described here for the sake of brevity.

[0124] For ease of understanding, the following describes a solution in which the AF sends the first information in an embodiment of the present application in conjunction with Example 3.

[0125] In Example 3, it is assumed that the first information is associated with a QoS flow, or the first information is associated with a service data flow. FIG6 is a schematic flow chart of a transmission scheme for the first information in another embodiment of the present application. The method shown in FIG6 includes steps S610 to S650.

[0126] In step S610, the AF sends a message 1 to the second core network device, where the message 1 carries the first information and indication information of the service data flow associated with the first information.

[0127] In the embodiments of the present application, the indication information of the service data flow is not limited. For example, the indication information of the service data flow may be a filter of the service data flow. For another example, the indication information of the service data flow may be an application identifier of the service data flow. For another example, the indication information of the service data flow may be a service identifier of the service data flow.

[0128] In step S620, the second core network device authorizes the first information.

[0129] In step S630, the second core network device sends a message 2 to the first core network device, wherein the message 2 carries the authorized first information and indication information of the service data flow associated with the first information.

[0130] In step S640, the first core network device sends a third request message to the access network device, wherein the third request message carries the authorized first information, and the first information is associated with the QoS flow.

[0131] In some implementations, the third request message may include a QoS flow establishment request or a QoS flow modification request.

[0132] In some implementations, the first core network network element binds the service data flow to a QoS flow with the same first information for transmission based on the first information of the service data flow, and carries the first information in a QoS flow establishment request or a QoS flow modification request together with the QoS flow identifier to the access network device to indicate that energy consumption should be considered when transmitting the QoS flow.

[0133] In step S650, the access network device schedules radio resources of the QoS flow based on the first information.

[0134] In some implementations, the access network device schedules the radio resources for the QoS flow based on network energy consumption. For example, when network energy consumption is high, data transmission for the QoS flow is delayed, thereby reducing access network device energy consumption without affecting the service transmission of other QoS flows. High network energy consumption can include one or more of the following: high access network device energy consumption, high terminal device energy consumption, and high energy consumption in providing transmission services for the terminal device's QoS flow.

[0135] The above describes, in conjunction with Examples 1 to 3, a scheme for scheduling wireless resources by an access network device based on first information in an embodiment of the present application. In some scenarios, the first core network device may not forward the first information to the access network device, but may instead sign a contract with the access network device for a first event for determining network energy consumption (also known as an "energy consumption event") to monitor network energy consumption.

[0136] In some implementations, the first event includes one or more of the following: an event for monitoring the energy consumption of a terminal device; an event for monitoring the energy consumption of an access network device serving the terminal device; an event for monitoring the energy consumption of service transmission provided by the terminal device; an event for monitoring the energy consumption of transmission provided by some or all terminal devices associated with a QoS flow; and an event for monitoring the energy consumption of a network slice associated with a QoS flow.

[0137] Taking an event for monitoring the energy consumption of a terminal device as an example, in some implementations, the event may include that the energy consumption of the terminal device exceeds an energy consumption threshold. In other implementations, the event may include that the energy consumption of the terminal device is within an energy consumption range.

[0138] Taking an event for monitoring the energy consumption of an access network device serving a terminal device as an example, in some implementations, the event may include the energy consumption of the access network device exceeding an energy consumption threshold. In other implementations, the event may include the energy consumption of the access network device being within an energy consumption range.

[0139] Taking an event for monitoring the energy consumption of a terminal device for providing service transmission as an example, in some implementations, the event may include the energy consumption of the terminal device for providing service transmission exceeding an energy consumption threshold. In other implementations, the event may include the energy consumption of the terminal device for providing service transmission falling within an energy consumption range.

[0140] Taking an event for monitoring the energy consumption of transmission provided by some or all terminal devices associated with a QoS flow as an example, in some implementations, the event may include that the energy consumption of transmission provided by some or all terminal devices associated with the QoS flow is higher than an energy consumption threshold. In other implementations, the event may include that the energy consumption of transmission provided by some or all terminal devices associated with the QoS flow is within an energy consumption range.

[0141] Taking an event for monitoring the energy consumption of a network slice associated with a QoS flow as an example, in some implementations, the event may include that the energy consumption of the network slice associated with the QoS flow is higher than an energy consumption threshold. In other implementations, the event may include that the energy consumption of the network slice associated with the QoS flow is within an energy consumption range.

[0142] In an embodiment of the present application, the above-mentioned energy consumption range and / or energy consumption threshold may be configured based on one or more of the following information: predefined information; preconfigured information and configuration information of the network device.

[0143] In some implementations, the subscription for the first event may be triggered based on the first information. That is, step S310 includes: the first core network device sending the first information to the second core network device; and the method further includes: the first core network device receiving the second information sent by the second core network device, where the second information is used to subscribe to the first event associated with the first information.

[0144] In some implementations, the first core network device may instruct the access network device to sign up for the first event. That is, the method further includes: the first core network device sending second information to the access network device. Of course, in this embodiment of the present application, the access network device may determine the first event through pre-definition or pre-configuration. In this case, to reduce transmission signaling overhead, the first core network device may not send the second information to the access network device.

[0145] In some implementations, after receiving the second information, the access network device may monitor the first event and transmit the monitoring results of the first event to the second core network device via third information, so that the second core network device can implement a control strategy for adjusting network energy consumption based on the monitoring results. That is, the above method further includes: the first core network device receiving the third information transmitted by the access network device, the third information including the monitoring results of the first event; and / or the first core network device transmitting the third information to the second core network device, the third information being used to determine the control strategy.

[0146] In the embodiments of the present application, the monitoring results are not specifically limited. For example, the monitoring result of the first event can be used to indicate the occurrence of the first event. For another example, the monitoring result of the first event can be used to indicate the network energy consumption associated with the first event. Taking the event that the first event is used to monitor the energy consumption of the terminal device as an example, the monitoring result may include the energy consumption of the terminal device. Taking the event that the first event is used to monitor the energy consumption of the access network device serving the terminal device as an example, the monitoring result may include the energy consumption of the access network device serving the terminal device. Taking the event that the first event includes an event for monitoring the energy consumption of the terminal device providing service transmission as an example, the monitoring result may include the energy consumption of the terminal device providing service transmission. Taking the event that the first event includes an event for monitoring the energy consumption of the terminal device providing transmission associated with some or all of the QoS flows as an example, the monitoring result may include the energy consumption of the terminal device providing transmission associated with some or all of the QoS flows. Taking the event that the first event includes an event for monitoring the energy consumption of the network slice associated with the QoS flow as an example, the monitoring result may include the energy consumption of the network slice associated with the QoS flow.

[0147] In the embodiments of the present application, the control strategy is not limited. In some implementations, the control strategy may include a QoS control strategy, that is, the second core network device can adjust the network energy consumption by adjusting the QoS parameters. For example, the second core network device can increase the transmission delay in the QoS parameters to reduce network energy consumption. For another example, the second core network device can increase the bit error rate in the QoS parameters to reduce network energy consumption. In other implementations, the control strategy may include a gating control strategy, that is, the second core network device can adjust the data transmission by controlling the opening or closing of the gate to achieve the purpose of controlling network energy consumption. For example, the second core network device can use the gate control strategy to block data transmission to reduce transmission energy consumption.

[0148] For ease of understanding, the following describes the scheme for signing the first event in the embodiments of this application in combination with Example 4 and Example 5.

The first event may include that the energy consumption of the access network device exceeds the energy consumption threshold, or that the energy consumption of the access network device providing transmission services to the terminal device exceeds the energy consumption threshold.

[0157] In step S760, the first core network device sends the monitoring result of the first event to the second core network device.

[0158] In step S770, the second core network device formulates a control strategy based on the monitoring result of the first event.

Specifically, the second core network device may adjust network energy consumption by adjusting the QoS parameters of the terminal device. For example, the second core network device may increase the transmission delay within the QoS parameters of the terminal device to reduce network energy consumption. For another example, the second core network device may increase the bit error rate within the QoS parameters of the terminal device to reduce network energy consumption.

[0160] In other implementations, the control strategy may include a gating control strategy.

[0166] In step S840, the first core network device sends second information to the access network device.

[0167] In step S850, the access network device monitors the first event based on the second information.

[0168] For example, when a first event occurs, the first event is reported to the first core network element. The first event may include that the energy consumption of the access network device exceeds the energy consumption threshold, or that the energy consumption of the access network device providing transmission services for the QoS flow exceeds the energy consumption threshold.

[0169] In step S860, the access network device sends the monitoring result of the first event to the second core network device through the first core network device.

[0170] In step S870, the second core network device formulates a control strategy based on the monitoring result of the first event.

[0171] In some implementations, the control policy may include a QoS control policy. Specifically, the second core network device may adjust network energy consumption by adjusting the QoS parameters of the service data flow. For example, the second core network device may increase the transmission delay in the QoS parameters of the service data flow to reduce network energy consumption.
