Separate CP and UP Transmission Channels for Wireless Connection Stability
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In wireless communications networks, the simultaneous interruption of control plane (CP) and user plane (UP) connections due to changes in configuration leads to diminished user experience, as both planes share the same transmission and physical channels, necessitating simultaneous reconfiguration and potentially causing call drops and reducing network throughput.
Innovation Solution
A method and apparatus that establish separate transmission and physical channels for CP and UP connections, allowing independent reconfiguration of each plane without affecting the other, ensuring that changes in one plane do not interrupt the other, thereby improving user experience and network efficiency.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Device complexity
If CP and UP are multiplexed in the same transmission channel and physical channel, then device complexity is reduced, but reliability deteriorates due to simultaneous interruption of both connections when configuration changes occur
Solution Approach 1:
The patent divides the transmission channel into separate logical channels: a first logical channel for CP connection and a second logical channel for UP connection. This segmentation allows independent configuration and management of control plane and user plane connections, preventing simultaneous interruption when configuration changes occur.
Solution Approach 2:
The patent introduces an additional dimension of separation by assigning different physical channels to CP and UP connections. The CP connection uses a first physical channel while the UP connection uses a second physical channel, creating spatial separation in the channel dimension that enables independent reconfiguration without mutual interference.
2Ease of operation
If CP and UP share the same transmission channel, then ease of operation is improved, but loss of time increases due to simultaneous reconfiguration requirements
Solution Approach 1:
By segmenting the transmission channel into separate logical channels for CP and UP, the patent enables independent configuration procedures. The network can reconfigure the UP connection without affecting the CP connection, and vice versa, thereby reducing the time required for reconfiguration operations.
Solution Approach 2:
The patent establishes separate logical channel configurations in advance, creating predefined pathways for CP and UP connections. This preliminary separation allows the network to perform configuration changes more efficiently by targeting specific logical channels rather than reconfiguring a shared channel that carries both planes.
3Device complexity
If CP and UP are multiplexed in the same physical channel, then device complexity is reduced, but adaptability deteriorates when different QoS requirements need to be met
Solution Approach 1:
The patent segments the physical channel resources by creating separate logical channels that can be independently configured with different QoS parameters. The first logical channel for CP connection and the second logical channel for UP connection can have different quality of service settings, enabling flexible adaptation to varying requirements while maintaining manageable complexity through standardized segmentation.
Solution Approach 2:
The patent applies local quality by allowing different QoS characteristics to be assigned to different logical channels. The CP connection can have one set of QoS parameters optimized for control signaling, while the UP connection can have different QoS parameters optimized for user data transmission, enabling localized optimization without affecting the entire channel structure.

AI summary
The present application provide a method includes: establishing, by a base station, a CP connection to a UE according to a configuration parameter of the CP connection and a UP connection to the UE according to a configuration parameter of the UP connection, where a transmission channel occupied by the CP connection which is indicated by the configuration parameter of the CP connection is different from the transmission channel occupied by the UP connection which is indicated by the configuration parameter of the UP connection, and transmission channels occupied by the CP connection and UP connection are also different. Therefore, the CP connection and the UP connection are not interrupted at the same time, which leads to no call drop occurring in a communication connection and improves user experience; and reduces a time delay, increases a network throughput, and further improves data transmission flexibility in an UP connection.
