In order to facilitate understanding by those skilled in the art, the embodiments of the present disclosure enumerate multiple implementations to clearly describe the technical solutions of the embodiments of the present disclosure. Of course, those skilled in the art can understand that the multiple embodiments provided in the embodiments of the present disclosure can be executed alone or in combination with the methods of other embodiments in the embodiments of the present disclosure. They can also be executed alone or in combination. It is then executed together with some methods in other related technologies; the embodiments of the present disclosure do not limit this.

In order to better understand the technical solutions described in any embodiment of the present disclosure, first, the application scenarios in related technologies are described:

Mobile media services, cloud augmented reality (AR, Augmented Reality) or virtual reality (VR, Virtual Reality) and other extended reality (XR, Extended Reality) services, cloud games, video-based machine or drone remote control and other services, It is expected to contribute increasingly higher traffic to 5G networks.

In addition to audio and video streams, XR services also involve multi-modal data streams, such as biological tactile sensing data streams. These multi-modal data are data input from the same device or different devices (including sensors) describing the same business or application. These data may be output to one or more destination device terminals. Each data stream in multimodal data often has a certain or even strong correlation, for example, the synchronization of audio and video streams, the synchronization of tactile and visual, etc. There are some common characteristics in the data flow itself of this type of media business, among each data flow, and in the network transmission requirements of these business data flows. The effective identification and utilization of these characteristics will be more conducive to the transmission and operation of networks and services. Control is also more conducive to business security and user experience.

However, the 5GS system uses a universal QoS mechanism to process various data services including XR services. It does not fully consider the characteristics of XR media services and cannot effectively support differentiated uplink and downlink requirements, such as uplink data reliability and Asymmetric requirements for downlink data bandwidth. At the same time, XR media data streams have the characteristics of high bandwidth, low latency and high reliability requirements, resulting in prominent energy consumption. The energy consumption plan is also an important factor affecting business usage and user experience.

In some embodiments, based on the existing UE implementation, multiple solutions can be applied locally in the UE according to the battery power. For example, when the battery power exceeds 80%, maintain a high screen refresh rate for all services; when the battery power is low, When the battery level is below 80%, maintain a medium screen refresh rate for all services; when the battery level is below or below 20%, close some non-mandatory and high-power-consuming threads or applications; when the battery level is below 10%, Shut down or disable all non-mandatory or power-hungry threads or applications. However, reducing the QoS level of some specific services when battery power is low has never been considered.

In some embodiments, "UE battery power change" is defined as an access-related policy control request trigger and/or a non-access-related policy control request trigger. The Policy Control Function (PCF, Policy Control Function) subscribes to the Access and Mobility Management Function (AMF, Access and Mobility Management Function) or Session Management Function (SMF, Session Management Function) when the UE battery power changes. When receiving the "change UE battery level" event, PCF determines a policy based on the current UE battery level, for example, selects a QoS level corresponding to a low or ultra-low battery level for service.

In some embodiments, when receiving a "UE battery change" event from the Access and Mobility Management Function (AMF, Access and Mobility Management Function), the PCF must evaluate all UE services or UE Protocol Data Units (PDU, Protocol Data Unit) session strategy. When receiving a "UE battery change" event from the SMF, the PCF evaluates the policy for all UE services or UE PDU sessions managed by the SMF. For specific services subject to power saving constraints, either multiple policy levels respectively associated with different UE battery levels are predefined, or the UE dynamically requests policy levels subject to the current UE battery level. UE battery level can be immediately considered for policy determination, or can be stored by the PCF to the UDR for later use. It can be used for policy determination together with a combination of other events, for example, when out of credit, the guaranteed flow bit rate (GFBR, Guaranteed Flow Bit Rate) of the QoS flow can no longer be guaranteed, or the network resources are limited. The UE battery level is also reported by the PCF to the Application Function (AF) so that the AF can take some measures (e.g., change the codec) to maintain a consistent policy.

Step b4: SMF detects subscription data and/or subscription events, and determines at least one of the following in combination with local policies: whether to create the PDU session; whether to perform subscription event reporting; whether to perform local policies; and whether to perform QoS authorization. It should be noted that if there is no PCF deployment, SMF performs static rule activation and QoS authorization. For example, if the terminal status change event is subscribed, the SMF determines whether the terminal status changes or whether the subscription reporting conditions are met based on the terminal status information; and performs a reporting operation according to the subscription and reporting requirements. For example, it is determined whether the status indicated by the terminal status information complies with the user subscription and local policies (for example, whether the status indicated by the terminal status information can create a PDU session). If the status indicated by the terminal status information does not meet the PDU session creation requirements, the XRM service and the /or PDU session creation for multi-modal services, or accept PDU session creation based on local policies but does not support XRM services and/or multi-modal services;

Step c2: AMF stores the terminal status information in the terminal context;

Step c3: AMF checks the subscription data and/or subscription events to determine whether to report the subscription events. For example, if the terminal status change event is subscribed, it is determined whether the subscription reporting conditions are met; after the subscription reporting conditions are met, reporting is performed according to the subscription and reporting requirements. The subscription reporting conditions may include at least one of the following: terminal status changes; meeting a threshold; suitable or changed power supply mode; receiving terminal status information; meeting the reporting cycle;
