Problems solved by technology

Therefore, the number of users supported by the existing cell system is small, and it cannot meet the system user capacity requirements of the future network.
Moreover, in a wireless communication system, such as the fifth generation mobile communication technology (5G for short) system, due to the fluctuation characteristics of the wireless channel, the channel capacity fluctuates, which in turn increases the packet error rate of the XR service. Increased latency (increased packet error rate increases the number of retransmissions), which further leads to a series of problems such as freezes, blurred screens, and black edges in XR services, seriously affecting user experience

Abstract

The embodiment of the invention discloses a data transmission method and a communication device. The method comprises the steps that a first core network function entity receives multi-stream transmission information of a service, wherein the multi-stream transmission information is used for indicating the service to be transmitted through first shunt data and second shunt data; the first core network function entity generates first quality of service (QoS) configuration information and second QoS configuration information according to the multi-stream transmission information, wherein the first QoS configuration information corresponds to the first offload data, and the second QoS configuration information corresponds to the second offload data; and the first core network function entity outputs the first QoS configuration information and the second QoS configuration information. By adopting the embodiment of the invention, the transmission requirements of high service rate and low delay can be met, and the use experience of a user is improved.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a data transmission method and a communications device. Background technique [0002] With the continuous development of communication technology, some services with high-speed, low-latency transmission requirements are becoming more and more popular. For example, with the continuous progress and improvement of extended reality (extended reality, XR) technology, related industries have developed vigorously. Today, extended reality technology has entered various fields closely related to people's production and life, such as education, entertainment, military, medical care, environmental protection, transportation, and public health. Extended reality is a general term for various reality-related technologies, including: virtual reality (virtual reality, referred to as VR), augmented reality (augmented reality, AR) and mixed reality (mixed reality, referred to...
