COMMUNICATION METHOD AND APPARATUS

Smart overview of the Invention

The patent application involves a communication method and apparatus designed to enhance data packet transmission in communication technologies, specifically in the context of tactile internet services. The apparatus utilizes processors to encode signals into data packets, which include information about a tactile sensing threshold. This threshold is crucial for ensuring reliable data transmission, particularly for services requiring real-time interaction, such as extended reality (XR) and remote control applications.

Technical Context

The invention is set against the backdrop of advancements in 5G communication systems, which offer reduced latency and increased capacity. These features are essential for multimedia services like video streaming, cloud gaming, and XR applications that demand high real-time performance. The tactile internet extends these capabilities by incorporating a tactile dimension, enabling remote touch and control across various fields such as industrial automation and healthcare.

Methodology

The communication method involves encoding a first signal to create a data packet with indication information about the tactile sensing threshold. This packet is sent to a user plane function (UPF) network element. If certain conditions are met between signals and the threshold, subsequent signals are encoded into additional data packets, maintaining the same tactile flow. This process ensures efficient use of transmission resources by reducing unnecessary signal transmissions.

Implementation Details

The method is applicable to servers or modules within servers, such as chips or processors. It can also be implemented via software capable of performing server functions. The UPF network element plays a crucial role by receiving data packets from the server and forwarding them to access network devices using quality of service (QoS) flows that match the tactile sensing threshold, thereby ensuring consistent reliability.

Benefits and Applications

This approach allows for improved matching between tactile flows and their corresponding thresholds, enhancing the reliability of multi-modal services. By filtering out signals with minor differences from previous ones, it optimizes resource usage. The method supports various applications, including immersive XR experiences, precise remote control operations, and educational tools that require fine motor skill training.
