5G Base Station TSN Clock Conversion for Radio Resource Allocation
Find Innovative SolutionsGenerate Solutions
Solution Overview
Problem
In a converged 5G and Time-Sensitive Networking (TSN) network, the clock inconsistency between the 5G and TSN networks leads to inaccurate resource allocation for data packets, as the 5G base station cannot accurately determine the arrival time of data packets from the TSN network.
Innovation Solution
The proposed solution involves obtaining a traffic pattern with time information specific to the 5G clock and using it to determine the arrival time of data packets, allowing for accurate radio resource allocation by synchronizing the clock information between the access network device and the TSN network.
Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Reliability
If the 5G network and TSN network are converged with virtualization, then end-to-end reliable transmission is enabled, but clock inconsistency prevents accurate resource allocation
Solution Approach 1:
The patent introduces a clock relationship conversion mechanism as an intermediary between the 5G clock and TSN clock. The base station obtains the clock relationship information (offset and/or frequency ratio) and uses it to convert arrival time from TSN clock reference to 5G clock reference, enabling accurate resource allocation despite clock inconsistency between networks
Solution Approach 2:
The patent changes the time reference parameter from TSN clock to 5G clock by applying clock relationship conversion. The base station converts the arrival time parameter using the obtained clock relationship (offset and frequency ratio), transforming the time measurement into the 5G network's time system to enable accurate resource allocation
2Ease of operation
If the base station uses its own clock for resource allocation, then resource allocation is simplified, but it cannot accurately determine arrival time of packets from TSN network
Solution Approach 1:
The clock relationship information acts as an intermediary that bridges the base station's 5G clock and the TSN network's clock system. By obtaining and applying this conversion information, the base station can continue using its own clock for resource allocation while accurately determining TSN packet arrival times through time conversion
3Productivity
If the base station allocates resources without accurate arrival time information, then resource allocation can proceed, but transmission efficiency and reliability deteriorate
Solution Approach 1:
The base station performs preliminary action by obtaining the clock relationship information between 5G clock and TSN clock before resource allocation. This advance preparation enables the base station to accurately convert arrival times and allocate radio resources appropriately, thereby improving both transmission efficiency and reliability

AI summary
A communication method enables a base station to allocate a radio resource to a data packet of a time sensitive networking (TSN) network in a scenario in which the TSN network transmits the data packet through a 5G network. The method includes: obtaining, by an access network device, a first traffic pattern, and allocating a radio resource to a first traffic based on the first traffic pattern. The first traffic pattern includes time information of the first traffic with respect to a first clock. The first clock is a clock used by a first network. The access network device belongs to the first network. The time information includes a time point and/or a period at/in which a data packet of the first traffic arrives at the first network.
