HANDLING OF CELL CHANGE FROM TARGET RELAY UE DURING INDIRECT PATH SWITCHING OF SIDELINK BASED U2N RELAY - A simplified explanation of the abstract

This abstract first appeared for US patent application 20240114400 titled 'HANDLING OF CELL CHANGE FROM TARGET RELAY UE DURING INDIRECT PATH SWITCHING OF SIDELINK BASED U2N RELAY

Simplified Explanation

The abstract describes a method for handling path switching in a cellular network, specifically when a candidate relay (CR) user equipment (UE) changes its serving cell or camping cell.

  • Sending a measurement report with a CR list from a UE to a network node.
  • Detecting a change in the CR UE's cell based on received messages.
  • Sending an updated measurement report to trigger path switch decisions or radio resource control connection re-establishment.

Potential Applications

This technology could be applied in mobile networks to improve handover procedures and optimize network performance.

Problems Solved

1. Efficient handling of path switching in cellular networks. 2. Enhancing network reliability and connectivity for CR UEs.

Benefits

1. Improved network efficiency and performance. 2. Enhanced user experience with seamless connectivity. 3. Reduced network congestion and latency.

Potential Commercial Applications

Optimizing path switching procedures in 5G networks for better user experience and network performance.

Possible Prior Art

There may be existing methods for path switching in cellular networks, but this specific approach of handling CR UEs changing cells may be a novel innovation.

Unanswered Questions

How does this method impact network latency during path switching procedures?

This article does not provide specific details on the impact of this method on network latency. Further research or testing may be needed to determine the latency implications of this approach.

What are the potential security implications of sending updated measurement reports in cellular networks?

The article does not address the security aspects of sending updated measurement reports. It would be important to consider potential security risks and safeguards when implementing this method in real-world networks.


Original Abstract Submitted

in an example embodiments, sending, by a remote user equipment (ue) of a source cell, towards a network node of the source cell a measurement report including a candidate relay (cr) list, wherein the cr list includes at least a cell identification for at least one cr ue for an indirect path switching from the source cell to a target cell associated with a cr ue; detecting a change of a serving cell or camping cell of the cr ue from the target cell to another cell based on receiving from the cr ue at least one message that indicates at least one cell identification for the cr ue is different than reported; and based on the detecting, sending an updated measurement report towards the network node triggering renewing a path switch decision or initiating a radio resource control connection re-establishment procedure with the source cell or the target cell.
