Description

TECHNICAL FIELD This disclosure generally relates to the field of communication technologies, and the inventnion in particular relates to a communication method and apparatus, as well as a computer-readable storage medium. BACKGROUND In recent years, with continuous development of a 5th generation (5th generation, 5G) communication system, a data transmission latency is continuously reduced, and a transmission capacity is increasingly large. The 5G communication system gradually penetrates into some multimedia services that have high real-time performance and a large data capacity requirement, such as video transmission, cloud gaming (cloud gaming), and extended reality (extended reality, XR). XR may include virtual reality (virtual reality, VR) and augmented reality (augmented reality, AR). As a new service, a multi-modal service is added with a tactile experience dimension on the basis of XR, which can implement remote touch and remote control, and implement remote sensing in a plurality of aspects such as vision, auditory, tactility, and kinesthetics. The multi-modal service has great development space in industrial automation, healthcare, distance education, and other related fields, provides users with comprehensive interactive experience, and has great application value and commercial potential. As a type of multi-modal services, tactile internet services can be classified into the following types: Immersive tactile XR: Through complete simulation and real-time interaction of sensory information such as vision, auditory, and tactility, the immersive tactile XR can create immersive, empathetic, and realistic experience for users, and take the users through the virtual and real worlds. Remote control: The tactile internet further enables tactility, which can significantly improve operators' sense of presence and improve operation precision. The remote control may be widely applied to scenarios such as industry and medical treatment. Education and training: When learners execute a task involving fine motor skills, instructors can feel learners' movements and make corrections if necessary. The learners can see, hear, and feel exact movements that their instructors make, whether they are engineers, pilots, or surgeons. Tactile broadcast: Tactile features are introduced on the basis of conventional broadcast, and tactile flows and broadcast flows are transmitted in a channel-associated manner, which can further improve viewing experience of audience. It can be learned that in the multi-modal service, the users may complete various things through tactility. However, in the multi-modal service, how to resolve a problem of mismatch between a tactile sensing threshold and reliability needs to be further studied.

SUMMARY The object of the present invention is to provide a communication method and apparatus, as well as a computer-reable storage medium, to include, in a data packet, indication information indicating a tactile sensing threshold, to ensure matching between the tactile sensing threshold and reliability. This object is solved according to the independent claims 1, 2, 5, 6 and further embodiments an improvements of the invention are listed in the dependent claims. According to a first aspect, this application discloses a communication method. The communication method may be applied to a server, may be applied to a module (for example, a chip or a processor) in a server, or may be applied to a logical module or software that can implement all or some functions of a server. The following provides descriptions by using an example in which the method is performed by the server. The communication method may include: The server encodes a first signal to obtain a first data packet, where the first data packet includes first indication information indicating a first tactile sensing threshold; sends the first data packet to a user plane function (user plane function, UPF) network element; when the first signal, a second signal, and the first tactile sensing threshold meet a first condition, encodes the second signal to obtain a second data packet, where the second data packet includes second indication information indicating the first tactile sensing threshold, and the first signal and the second signal correspond to a same tactile flow; and sends the second data packet to the UPF network element. In this embodiment of this application, a data packet sent by the server to the UPF network element includes indication information of a tactile sensing threshold, so that the UPF network element can send the data packet to an access network device by using a quality of service (quality of service, QoS) flow corresponding to the tactile sensing threshold, to ensure matching between the tactile sensing threshold and reliability.
