In the existing O-RAN architecture, the network and cloud platform infrastructure resources are isolated from each other. The only way to achieve the interaction between services, networks and resources is to collect data and control policies through the centralized SMO, and collect and deliver cloud platform (O-Cloud) resource configuration information to network functions (including centralized units (CU), distributed units (DU), radio units (RU), non-real-time wireless intelligent controllers (Non-RT RIC), near-real-time wireless intelligent controllers (Near-RT RIC), etc.) through the O1 interface.

It should be understood that the terms used in this way are interchangeable under appropriate circumstances, so that the embodiments of the present application can be implemented in an order other than those illustrated or described here, and the objects distinguished by "first" and "second" are generally of the same type, and the number of objects is not limited. For example, the first object can be one or more.

[0139] In one implementation of the present application, the first network element includes at least one of the following: SMO, NFVO, MEO, VNFM, CNFM, Non-RT RIC, and a network element management system.

[0140] In an embodiment of the present application, by authenticating the network function and sending a first message to the cloud platform, it is used to support cloud resource energy saving or wake-up control initiated by the network function (instance), so that the cloud platform supports energy saving triggered by the network function and performance recovery in the energy-saving state.

[0141] Taking the first network element as SMO as an example, the time granularity of network and resource collaborative control for SMO in related technologies is at the second level, and near real-time resource and network collaboration is not currently supported. If you want to achieve higher real-time resource and network collaboration, especially low-latency energy-saving control triggered by network functions or restore high-performance mode control from energy-saving mode, you need to enhance SMO to implement authorization for network functions and target energy-saving related controls, so that the cloud platform supports energy saving initiated by network functions, ensures network security and centralized management, and at the same time guarantees business experience, and achieves the collaboration between cloud platform energy saving initiated by network functions and cloud platform energy saving solutions initiated by existing management and orchestration.

[0142] In one implementation of the present application, the first network element authorizes the network function that initiates energy-saving control, or the first network element may also define the object or control content that initiates energy-saving control according to different cloud resource control priorities and real-time requirements. Then the first network element sends at least one of the network function information, cloud resource control type, cloud platform resource configuration information, cloud resource control priority, cloud resource control waiting time (or control waiting delay requirement), network function type and network function priority of the network function as the configuration information of the network function to the cloud platform through the enhanced O2 interface. After the cloud platform receives the configuration information of the network function, it receives the energy-saving control request from the network function according to the energy-saving authority of the network function, and performs relevant cloud resource control. The process is as follows: Figure 4 shown.

[0143] Step 401-1: <Optional> After receiving a cloud resource control request for an instantiated network function, the first network element authenticates the network function.

[0144] Step 401-2: The first network element authenticates the network function that initiates energy-saving control, and generates at least one of the network function information of the authenticated network function (or network function instance) (indicated by NF ID / NF Instance ID), cloud resource control type, cloud platform resource configuration information corresponding to the cloud resource control type, cloud resource control priority, cloud resource control waiting time, network function type and network function priority as the configuration information of the network function (or network function instance) when the first network element deploys the network function for the first time.

[0145] Alternatively, after receiving a cloud resource control request for an instantiated network function, the network function is authenticated, and configuration information of the authenticated network function (instance) is updated.

[0146] Step 402: The first network element sends the generated or updated configuration information of the network function (or network function instance) to the cloud platform through the O2 interface.

[0147] Optionally, the configuration information includes at least one of the following: network function information, cloud resource control type, cloud platform resource configuration information, cloud resource control priority, cloud resource control waiting time, network function type, network function priority, etc.

[0148] Step 403: The first network element sends to the network function (or network function instance) at least one of the cloud resource control type supported by the network function, the cloud platform resource configuration information corresponding to the cloud resource control type supported by the network function, and the cloud resource control waiting time.

[0149] Optionally, step 403 also includes: the first network element sends an authentication response to the network function (or network function instance).

[0150] Among them, the resource identifiers corresponding to the cloud platform include: cloud platform identifier (O-Cloud ID), server node ID (Server Node ID), CPU core identifier (uniquely identifying the CPU core in the server, such as the processor (processor) / CPU identifier in x86 servers, or the node identifier (node ​​id) + core identifier (coreid) in non-uniform memory access (NUMA), etc.

[0151] Step 404: The cloud platform receives a cloud resource control request from the network function, and performs corresponding cloud resource control according to the configuration information of the network function (instance) configured by the first network element.

[0152] Optionally, the cloud platform resource configuration information corresponding to the energy-saving control includes at least one of the following:

[0153] -CPU frequency or CPU P-State enable / disable, and / or target CPU core identifier, and / or corresponding CPU core frequency reduction parameters, and / or CPU core P-State parameter modification, for example, P0->P1->...->Pn;

[0154] -CPU power state or CPU C-State enable / disable, and / or target CPU core identifier, and / or corresponding CPU core voltage reduction parameter, and / or CPU core C-State parameter modification, for example, C0->C1->...->C6;

[0155] -CPU core binding, CPU core pining enable / disable, and / or the target bound CPU core number or the reduced CPU core number bound to the network function, and / or the target CPU core identifier of the network function to be reduced, and / or the correspondence between the network function and the CPU core binding.

[0156] Optionally, the cloud platform resource configuration information corresponding to the wake-up control includes at least one of the following:

[0157] -CPU frequency or CPU P-State enable / disable, and / or target CPU core identifier, and / or corresponding core CPU core frequency increase parameter, and / or CPU core P-State parameter modification, for example, Pn->...->P1->P0;

[0158] -CPU power state or CPU C-State enable / disable, and / or target CPU core identifier, and / or corresponding CPU core voltage boost parameter, and / or CPU core C-State parameter modification, for example, C6->...->C1->C0;

[0159] -CPU core binding, CPU core pining enable / disable, and / or the target bound CPU core number or the increased number of CPU cores bound to the network function, and / or the target cpu core identifier of the network function to be added, and / or the correspondence between the network function and the CPU core binding.

[0160] In one embodiment of the present invention, the first network element authorizes the network function and the target energy-saving related control, and sends the authorized control authority and related configuration of the network function to the cloud platform, so that the cloud platform supports the energy saving triggered by the network function and the performance recovery in the energy-saving state, and coordinates the low-latency energy-saving characteristics triggered by the network function with the traditional non-real-time energy saving by configuring the interrupt priority, so as to ensure the security of the execution of multi-dimensional energy-saving strategies, thereby meeting the requirements of safe, controllable and low-latency energy-saving related control.

[0161] Example 1: Configuration based on cloud resource control priority and / or waiting delay requirements

[0162] The first network element configures different control priorities and / or cloud resource control waiting times according to the importance and real-time nature of energy-saving control or wake-up control, wherein the cloud resource control waiting time is used to indicate the waiting time for the cloud platform to execute the corresponding cloud resource control. For example, according to the cloud resource control type and the cloud platform resource configuration information corresponding to the cloud resource control type, the cloud resource control waiting time and / or cloud resource control priority are set, as shown in Table 1.

[0163]

[0164]

[0165] Table 1

[0166] According to the different cloud resource control priorities defined by the cloud platform resource configuration information shown in Table 1, the cloud resource control waiting time (Timer) can be further configured optionally, that is, the cloud resource control waiting time is used to indicate that after the cloud platform receives the cloud resource control request from the network function, it continues to wait and listen to the interface between the network function, and executes the corresponding cloud resource control when the time specified by the cloud resource control waiting time is met. For example, when the cloud resource control type is wake-up control, Timer = 0, then the cloud platform directly executes the corresponding cloud resource control after receiving the network function request; when the cloud resource control type is energy-saving control, Timer = x, then the cloud platform continues to wait and listen to the cloud resource control request from the network function within x time after receiving the network function request, and executes the corresponding cloud resource control, such as energy-saving frequency reduction control, when the cloud resource control waiting time expires.

[0167] Optionally, the cloud resource control waiting time (Timer) and the cloud resource control priority may be sent to the cloud platform via the configuration information of the network function (instance).

[0168] Alternatively, the correspondence between the cloud resource control priority and the cloud resource control waiting time can be issued when the first network element initializes the cloud platform, or pre-configured in the cloud platform. After the network function is authorized, the cloud platform resource configuration information and the cloud resource control waiting time executable by the authorized network function (instance) are sent to the cloud platform, and the cloud platform obtains the corresponding cloud resource control waiting time based on the stored correspondence.

[0169] Alternatively, the correspondence between the cloud platform resource configuration information and the cloud resource control priority and cloud resource control waiting time can be issued when the first network element initializes the cloud platform, or pre-configured in the cloud platform. After the network function is authorized, the cloud platform resource configuration information executable by the authorized network function (instance) is sent to the cloud platform. The cloud platform obtains the cloud resource control priority and cloud resource control waiting time of the corresponding cloud resource control based on the stored correspondence.

[0170] Optionally, the cloud resource control waiting time can be pre-configured or configured when the network function is instantiated. To meet the flexibility of different network functions for the cloud resource control waiting time, this embodiment supports Figure 4 In step 403, a time offset is added to the cloud resource control request sent by the network function to the cloud platform, so as to adjust the configured cloud resource control waiting time according to the network function requirements.

[0171] Embodiment 2: Configuring network function priority based on network function type.

[0172] In this embodiment, the first network element can implement cloud resource control in the service dimension by configuring the network function priorities of different network function types (such as DU / CU / nRT RIC) according to the real-time requirements of the network function to be authorized, as shown in Table 2.

[0173]

[0174] Table 2

[0175] According to the different network function priorities defined for different network functions as shown in Table 2, it can be used to indicate that when the cloud platform receives energy-saving control or wake-up control requests for multiple network functions, the requests corresponding to the high-priority network functions are executed first. For example, the DU with the highest real-time requirements and energy consumption has the highest priority.

[0176] In addition, Example 2 can be combined with Example 1. While indicating the network function priority, it can specify the cloud resource control type and cloud platform resource configuration information. It can also specify the cloud resource control priority and cloud resource control waiting time accordingly. Therefore, when the network function initiates an energy-saving control request, it only needs to specify the cloud resource configuration information. The cloud platform can query the corresponding relationship in the configuration information sent after the first network element is authorized, and execute the corresponding energy-saving control or wake-up control, thereby reducing the configuration overhead in the network function request.

[0177] For the configuration information of the network function (instance) described in steps 401-402, based on the virtual network function description (Virtualised Network Function Descriptor, VNFD) according to the network function virtualization (Network Functions Virtualisation, NFV) related technology, the fields that can be enhanced in this application can be implemented based on Example 3.

[0178] Embodiment 3: Standard fields to be enhanced based on NFV

[0179] In one embodiment of the application, based on the description of VNFD or further extended to the containerized network function description (Containerized Network Function Descriptor, CNFD) based on NFV related technologies, the energy-saving control related fields initiated by the network function are further enhanced, and sent by the first network element to the cloud platform during the instantiation of VNF / network function containerization (Containerized Network Function, CNF) or the modification of VNF / CNF configuration. In this way, the cloud platform is supported to perform energy-saving or high-performance configuration according to the energy-saving control or configuration information sent by the network function and the cloud platform interface. The details are shown in Table 3:

[0180]

[0181]

[0182]

[0183] Table 3

[0184] As shown in Table 3, the fields related to energy saving and high-performance recovery enhanced for VNFD / CNFD can be further added to the VNFD information element, or the deploymentFlavour field in the VNFD information element, or the table corresponding to the configurableProperties field in the VNFD information element, or further extended to the corresponding field of CNFD, so as to be used by the first network element to indicate to the cloud platform that the cloud platform supports cloud resource control initiated by the network function when deploying or updating the network function.

[0185] Specifically, with respect to step 403, the first network element sends the executable cloud resource control type, cloud platform resource configuration information and / or cloud resource control waiting time of the network function to the network function (instance), wherein the optional cloud resource control waiting time can be implemented based on Example 4.

[0186] Embodiment 4: Indicating executable cloud platform resource configuration information of a network function.

[0187] In one embodiment of the present application, after the corresponding network function is instantiated, the first network element sends the cloud resource control type, cloud platform resource configuration information, and / or cloud resource control waiting time that can be executed by the current network function to the instantiated network function (instance); or, optionally, the cloud resource control type, cloud platform resource configuration information, and / or cloud resource control waiting time can also be sent through an authentication response, as shown in Table 4.

[0188] Table 4

[0189]

[0190] The network function can configure the cloud resource control waiting time according to the cloud platform resource configuration information shown in Table 4, which is used to instruct the network function to generate an energy-saving control request to the cloud platform based on the collected network status and resource occupancy, and then continue to wait and monitor the network and cloud platform status. When the time specified by the cloud resource control waiting time is met and the status has not changed significantly, the energy-saving control request is sent to the corresponding cloud platform. For example, when the energy-saving frequency is reduced, Timer = x, then the network function generates an energy-saving control request, and does not send an energy-saving control request to the cloud platform within x time, and continues to monitor the network status and cloud resource occupancy. During this period, when the network status has a burst of traffic and insufficient resources, the wake-up control is immediately triggered, Timer = 0, and a wake-up control request is immediately sent to the cloud platform.

[0191] In addition, if the configuration described in this embodiment is adopted, the configuration information of the network function (instance) sent by the first network element to the cloud platform does not need to include the control waiting time, and the cloud platform directly executes the control request initiated by the network function after receiving it.

[0192] Specifically, the coordination between the low-latency energy-saving characteristics initiated by the network function and the traditional non-real-time energy saving can be implemented based on Example 5.

[0193] Example 5: Real-time and non-real-time energy-saving control coordination

[0194] In one embodiment of the present application, based on the cloud resource control type of the network function (instance) sent by the first network element to the cloud platform, and / or the cloud platform resource configuration information, and / or the cloud resource control priority, when the cloud platform receives a cloud resource control request from the network function, when the cloud resource control type is "wake-up control" or the cloud platform resource configuration information is the cloud platform resource configuration information corresponding to the recovery wake-up control type described in Table 4, according to the configured cloud resource control priority (0) and / or cloud resource control waiting time (0), the cloud resource related control being executed is directly interrupted, and the corresponding cloud platform resource configuration information is quickly executed, such as Figure 5 shown.

[0195] In addition, when the cloud platform receives a cloud resource control request from a network function, when the cloud resource control type is "energy-saving control" or the cloud resource configuration parameters are the cloud resource configuration parameters corresponding to the energy-saving control described in Table 4, it detects whether the energy-saving control initiated by the first network element has been received. If it has been received, it determines whether the energy-saving control initiated by the first network element has been executed (whether the execution status has been fed back to the first network element). After execution, it executes the corresponding cloud resource energy-saving control according to the cloud platform resource configuration information and / or time offset in the cloud resource control request sent by the network function, and in combination with the configured cloud resource control priority and / or cloud resource control waiting time. Otherwise, it is necessary to wait for the energy-saving control initiated by the first network element. In addition, when the cloud platform is executing the energy-saving control sent by the network function and receives the energy-saving control sent by the first network element, it can directly interrupt the currently executing content and execute the corresponding energy-saving control according to the request of the first network element, such as Figure 6 shown.

[0196] Through this embodiment, it is possible to ensure that the energy-saving control in the first network element has absolute centralized management, and prevent conflicts between traditional control and energy-saving control initiated by network functions. In addition, while achieving energy saving, when a service in energy-saving mode has a burst of service traffic, it supports the configured cloud resource control priority, so that the energy-saving control initiated by the network function can interrupt all current energy-saving related controls, and quickly restore the high-performance mode from the energy-saving mode, thereby maximizing the user experience.
