Host Device 5G Network Slicing Rule Distribution
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
Existing communication systems between client devices and networks via host devices do not fully leverage the benefits of 5G network slicing, such as customisation and traffic differentiation, when the client device communicates through a host device.
Innovation Solution
The method involves configuring communication between a client device and a host device using a first Radio Access Technology (RAT), where the host device communicates with a base station using a second RAT, such as 5G. The host device communicates network traffic rules, including UE Route Selection Policy (URSP) information, to the client device, which then configures its communication according to client traffic rules based on these network traffic rules.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the host device uses a best effort bearer to communicate data to or from the client device, then the communication is simple to implement, but the Quality of Service (QoS) criteria are not met
Solution Approach 1:
The patent applies preliminary action by pre-configuring QoS parameters and bearer settings on the host device before client devices connect. The host device maintains a pool of pre-established QoS profiles and bearer configurations that can be rapidly assigned to client devices, eliminating the need for complex real-time QoS negotiations and ensuring service quality is guaranteed from the outset of communication.
2Adaptability or versatility
If the host device acts as a WLAN hotspot, then Internet access is provided to client devices, but the benefits of 5G network slicing are not realized
Solution Approach 1:
The host device serves as an intermediary between the 5G network and client devices. It receives and processes network slicing information from the 5G base station, then translates and distributes this information to client devices. This intermediary role enables client devices to access 5G network slicing benefits without requiring them to directly implement complex 5G protocol stacks, thus maintaining ease of operation while achieving adaptability.
Solution Approach 2:
The host device pre-loads and caches network slicing information, URSP rules, and QoS parameters from the 5G network before client devices need them. This preliminary preparation allows the host device to rapidly configure multiple client devices with appropriate network slicing settings, making the system both adaptable to different service requirements and easy to operate.
3Adaptability or versatility
If the host device communicates with the base station using cellular interface, then network access is achieved, but traffic differentiation and customization are limited
Solution Approach 1:
The patent applies segmentation by dividing network traffic into distinct categories based on service types, applications, or QoS requirements. The host device implements traffic flow templates that segment uplink and downlink traffic into different bearers with specific QoS parameters. This segmentation enables fine-grained traffic differentiation and customization, allowing different applications to receive appropriate network resources while preserving complete traffic rule information through structured QoS parameter transmission.

AI summary
Communication between a client device and a host device using a first Radio Access Technology (RAT) may be configured. The host device communicates with a base station of a network using a second RAT, to provide services of the network to or from the client device. The communication between the host device and the base station distinguishes data traffic in accordance with a set of network traffic rules. Information relating to the set of network traffic rules is communicated from the host device to the client device. The communication between the client device and the host device using the first RAT is configured according to a set of client traffic rules that are based on the communicated information about the network traffic rules.
