METHOD AND DEVICE FOR RE-ESTABLISHING PDCP IN WIRELESS COMMUNICATION SYSTEM - A simplified explanation of the abstract
This abstract first appeared for US patent application 18460455 titled 'METHOD AND DEVICE FOR RE-ESTABLISHING PDCP IN WIRELESS COMMUNICATION SYSTEM
Simplified Explanation
The patent application describes a communication technique that combines IoT technology with a 5G communication system to achieve a higher data transmission rate compared to a 4G system. This technology can be used in various intelligent services such as smart home, smart building, smart city, smart car, healthcare, digital education, retail, security, and safety-related services.
- The patent application focuses on the operations of a terminal and a base station in a mobile communication system.
- It provides a method for a terminal to re-establish a PDCP (Packet Data Convergence Protocol) in a wireless communication system.
- The method involves receiving a message from a base station that includes PDCP re-establishment information on a DRB (Data Radio Bearer) where an RRC (Radio Resource Control) connection is set up.
- The terminal checks whether the PDCP re-establishment information includes configuration information of an SDAP (Service Data Adaptation Protocol) layer.
- Based on the checking result, the terminal determines whether to perform a PDCP re-establishment procedure to change the DRB operating as a PDCP from a first system to a second system.
Potential applications of this technology:
- Smart home: Enables seamless and high-speed data transmission between IoT devices in a smart home environment.
- Smart city: Facilitates efficient communication and data exchange between various IoT devices and systems in a smart city infrastructure.
- Smart car or connected car: Enhances connectivity and communication capabilities in connected cars, enabling advanced features such as real-time navigation, vehicle-to-vehicle communication, and remote diagnostics.
- Healthcare: Supports the transmission of medical data and enables remote monitoring and telemedicine services.
- Digital education: Enables interactive and immersive learning experiences through high-speed data transmission and connectivity between devices in educational settings.
- Retail: Enhances customer experience through personalized and location-based services, such as targeted advertisements and mobile payments.
- Security and safety-related services: Enables real-time surveillance, monitoring, and emergency response systems.
Problems solved by this technology:
- Higher data transmission rate: The combination of IoT technology and 5G communication system allows for faster and more efficient data transmission compared to the previous 4G system.
- Seamless connectivity: The method described in the patent application ensures smooth re-establishment of the PDCP, enabling uninterrupted communication between devices and systems.
- Compatibility between systems: The technology allows for the transition of a DRB from one system to another, ensuring compatibility and interoperability between different communication systems.
Benefits of this technology:
- Improved efficiency: The higher data transmission rate and seamless connectivity provided by this technology enhance the overall efficiency of IoT-based systems and services.
- Enhanced user experience: Faster and more reliable communication between devices and systems leads to a better user experience in various applications.
- Advanced capabilities: The combination of IoT and 5G technology enables the development of innovative and advanced features in areas such as smart homes, smart cities, and connected cars.
- Scalability: The technology can be applied to various industries and can accommodate the growing number of IoT devices and systems.
Original Abstract Submitted
Disclosed are a communication technique for merging IoT technology with a 5G communication system for supporting a data transmission rate higher than that of a 4G system and a system therefor. The present disclosure can be applied to intelligent services (for example, smart home, smart building, smart city, smart car or connected car, healthcare, digital education, retail, security, and safety related services, and the like) on the basis of 5G communication technology and IoT-related technology. The present invention relates to operations of a terminal and a base station in a mobile communication system. The present invention provides a method by which a terminal re-establishes a PDCP in a wireless communication system, the method comprising the steps of: receiving a message including PDCP re-establishment information on a DRB from a base station in which an RRC connection is set up; checking whether the PDCP re-establishment information includes configuration information of an SDAP layer; and determining whether to perform a PDCP re-establishment procedure for changing the DRB operating as a PDCP of a first system into a PDCP of a second system on the basis of the checking result.
