Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in efficiently supporting a wide range of devices with different data traffic profiles and types, particularly in scenarios involving small data transmissions with high latency tolerance, such as those expected in future 5G or new radio (NR) systems.
Innovation Solution
The proposed solution involves modifying paging procedures in wireless telecommunications networks to allow data communication with terminal devices in RRC connected inactive mode, using network allocated resources such as a cell-specific radio network temporary identifier (C-RNTI) allocated in a paging message, enabling data exchange without the terminal device entering an active RRC connected mode.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If terminal devices enter RRC connected mode for data communication, then data transmission capability is improved, but signaling overhead and power consumption increase
Solution Approach 1:
The patent segments the RRC connection states into multiple modes (RRC connected mode with sub-states, RRC inactive mode) to allow devices to operate in different connectivity levels based on data transmission needs. This segmentation enables small data transmissions to occur in lower-power inactive states while reserving full connected mode for larger data transfers, thus reducing overall power consumption without sacrificing necessary data transmission capability.
Solution Approach 2:
The patent introduces dynamic state transitions between RRC connected and inactive modes based on real-time data transmission requirements. The network can dynamically move devices between states, allowing terminal devices to remain in low-power inactive mode for small data transmissions and only transition to full connected mode when necessary, thereby optimizing the balance between data transmission capability and power consumption.
2Productivity
If terminal devices enter RRC connected mode for data communication, then data transmission capability is improved, but signaling overhead increases
Solution Approach 1:
The patent segments data transmission scenarios into different RRC states, allowing small data transmissions to occur in RRC inactive mode with minimal signaling, while reserving RRC connected mode for scenarios requiring full data transmission capability. This reduces overall signaling overhead by avoiding unnecessary connection establishment for small data packets.
Solution Approach 2:
The patent applies partial action by allowing terminal devices to perform limited data transmissions in RRC inactive mode without establishing a full RRC connection. This partial capability is sufficient for small data transmissions, avoiding the excessive signaling overhead associated with complete connection establishment while still enabling productive data communication.
3Adaptability or versatility
If wireless networks support a wide range of devices with different data traffic profiles, then device compatibility is improved, but network complexity increases
Solution Approach 1:
The patent creates a universal RRC state framework that can accommodate multiple device types and data traffic profiles within the same network infrastructure. By defining standardized inactive and connected modes with clear transition rules, the network can universally support diverse devices (IoT, mobile phones, tablets) without requiring device-specific complexity, as all devices operate within the same state management paradigm.
Data Source
AI summary
A method of communicating data between a radio network infrastructure and a terminal device in a wireless telecommunications network. The method comprises establishing at a radio network infrastructure element there is data available for communication between the radio network infrastructure and the terminal device and transmitting a paging message for the terminal device from the radio network infrastructure element. The paging message comprises an indication of an identifier for the terminal device and an indication of a network allocated resource for use in subsequently communicating the data between the radio network infrastructure element and the terminal device. In response to receiving the paging message the terminal device transmits to the radio network infrastructure element a paging response indicating the terminal device received the paging message, after which the data is communicated between the radio network infrastructure element and the terminal device using the network allocated resource.
