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 embodiments of the present disclosure, the application scenarios of sensing services are described below:

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 touch and vision, 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 one embodiment, various data services including XR services have the characteristics of high throughput, low latency and high reliability requirements, as well as the status of the terminal, such as heat level, battery power and processor load, etc. May affect user experience. Since high throughput requires high power consumption, it results in high terminal side temperature and processor load. Therefore, considering limited radio resources and end-to-end QoS policy control from a system perspective, 5GS should be enhanced to support the trade-offs between throughput, delay, reliability, and terminal status.

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 the session management function (SMF, Session Management Function) for changes in UE battery power. 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.
