Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Current wireless communication systems face challenges in accommodating explosive data traffic, requiring higher transmission rates and energy efficiency, especially with the increasing number of connected devices and demand for low latency, which existing technologies struggle to meet effectively.
Innovation Solution
A method is introduced to allocate the same IP address to multiple communication devices within a single wireless device, enabling the creation of multiple paths for data transmission by defining new signaling between core network entities, allowing for enhanced data transmission rates through optimized PDN connection procedures.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Productivity
If multiple communication devices are used for data transmission, then data transmission rate is improved, but device complexity increases
Solution Approach 1:
The patent segments the communication function by separating control plane signaling (handled by one communication device) from user plane data transmission (handled by multiple communication devices). This allows multiple devices to transmit data simultaneously while a single device manages the complex signaling procedures, thereby increasing data transmission rate without proportionally increasing overall system complexity
Solution Approach 2:
The patent merges the IP addresses of multiple communication devices into a single shared IP address at the network layer. This consolidation allows multiple devices to share a common network identity and participate in multi-path transmission without requiring separate complex signaling procedures for each device, thus improving productivity while managing device complexity
2Productivity
If multiple paths are established for data transmission, then network efficiency is improved, but signaling complexity increases
Solution Approach 1:
The patent extracts the complex signaling procedures from the data transmission paths themselves and consolidates them into dedicated control plane signaling. The signaling messages (PDN connectivity requests, attach requests) are separated from user data traffic, allowing multiple data paths to be established without each path carrying its own complex signaling overhead, thereby improving network efficiency while managing signaling complexity
Solution Approach 2:
The patent creates a universal signaling framework where a single set of signaling procedures and a shared IP address can manage multiple communication devices and multiple transmission paths simultaneously. This multi-functional approach allows the same signaling mechanism to handle multiple devices without requiring separate complex signaling for each path, thus improving network efficiency while controlling signaling complexity

AI summary
The present specification relates to a method for transmitting and receiving data using multiple communication devices included in a single wireless device in a wireless communication system, the method being performed by a first network entity and comprising the steps of: receiving, from one or more communication devices, a connectivity request message for requesting a connection to a core network for transmitting and receiving data; ascertaining, on the basis of the received connectivity request message, whether a second communication device linked to a first communication device exists; and if the second communication device linked to the first communication device exists, confirming whether the linked second communication device has requested creation of a bearer associated with a first identifier or has a bearer created for the first identifier.
