WIRELESS LOCAL AREA NETWORK MAKE-BEFORE-BREAK HANDOVER - A simplified explanation of the abstract

This abstract first appeared for US patent application 18340001 titled 'WIRELESS LOCAL AREA NETWORK MAKE-BEFORE-BREAK HANDOVER

Simplified Explanation

The present disclosure describes a method for wireless communication at a wireless node, involving initiating a handover from a first access point (AP) device to a second AP device within the same mobility domain entity.

• The method involves communicating with a first AP device via a first link and sending a message indicating the initiation of a handover to a second AP device.
• The wireless node then communicates with the second AP device via a second link after receiving an indication that context information has been transferred.
• Finally, the first link with the first AP device is disabled after receiving a trigger to do so.

Potential Applications

This technology can be applied in various wireless communication systems, such as mobile networks, Wi-Fi networks, and IoT devices, to facilitate seamless handover between access points.

Problems Solved

1. Seamless handover: The method ensures a smooth transition of the wireless node from one access point to another within the same mobility domain entity. 2. Context transfer: By transferring context information between access points, the method helps maintain the continuity of communication during handover.

Benefits

1. Improved connectivity: Users experience uninterrupted connectivity while moving between different access points. 2. Enhanced user experience: Seamless handover results in a better overall user experience with wireless networks.

Potential Commercial Applications

This technology can be beneficial for telecommunications companies, network equipment manufacturers, and IoT device manufacturers looking to enhance the performance and reliability of wireless communication systems.

Possible Prior Art

One possible prior art could be the handover protocols used in cellular networks to facilitate the transfer of mobile devices between base stations without losing connectivity.

How does this method handle potential interference during the handover process?

The abstract does not provide details on how the method mitigates interference issues that may arise during the handover process. This could be crucial for ensuring the seamless transition of the wireless node between access points.

What security measures are in place to protect the context information transferred between access points?

The abstract does not mention any security measures implemented to safeguard the context information transferred between access points. Ensuring the confidentiality and integrity of this information is essential for maintaining the security of the wireless communication system.

Original Abstract Submitted

Certain aspects of the present disclosure provide a method for wireless communication at a wireless node, generally including communicating, via a first link, with a first access point (AP) device affiliated with a single mobility domain (SMD) entity, outputting, for transmission to the first AP device, a first message including a first indication that the wireless node is initiating a handover of the wireless node from the first AP device to a second AP device affiliated with the SMD entity, communicating with the second AP device via a second link during the handover after obtaining a second indication that context information has been transferred from the first AP device to the second AP device, and disabling the first link with the first AP device after obtaining a third indication that triggers the wireless node to disable the first link with the first AP device.
