ROAMING CANDIDATE SELECTION WITH OVERLAPPING BASIC SERVICE SET (OBSS) DETECTION - A simplified explanation of the abstract

This abstract first appeared for US patent application 17477728 titled 'ROAMING CANDIDATE SELECTION WITH OVERLAPPING BASIC SERVICE SET (OBSS) DETECTION

Simplified Explanation

This patent application is about methods, devices, and systems for wireless roaming, specifically focusing on roaming candidate selection based on overlapping basic service set (OBSS) detection. Here are the key points:

  • The invention provides a method for a wireless station (STA) to identify OBSSs during an OBSS detection period and roam to a new access point (AP) based on the identified OBSSs when a roaming condition is met.
  • The STA stores information about each identified OBSS in an OBSS table.
  • When the roaming condition is met, the STA listens for beacon or probe response frames from other APs operating on the same wireless channel.
  • If the STA receives frames from one or more APs that match the OBSS table, it roams to the AP with the highest candidate score.

Potential applications of this technology:

  • Wireless network infrastructure: This technology can be used in the design and implementation of wireless network systems to improve roaming capabilities and enhance the overall performance of the network.
  • Mobile devices: Mobile devices such as smartphones, tablets, and laptops can benefit from this technology by seamlessly switching between access points for better connectivity and user experience.

Problems solved by this technology:

  • Seamless roaming: The technology addresses the issue of seamless roaming between access points in a wireless network, ensuring uninterrupted connectivity for users.
  • Efficient network utilization: By selecting the best candidate access point based on OBSS detection, the technology optimizes network utilization and reduces congestion.

Benefits of this technology:

  • Improved user experience: Users can enjoy uninterrupted connectivity and seamless roaming between access points, resulting in a smoother and more reliable wireless network experience.
  • Enhanced network performance: The technology enables efficient utilization of network resources, reducing congestion and improving overall network performance.
  • Simplified network management: The OBSS table allows for easier management and selection of access points, simplifying the configuration and maintenance of wireless networks.


Original Abstract Submitted

This disclosure provides methods, devices and systems for wireless roaming. Some implementations more specifically relate to roaming candidate selection based on overlapping basic service set (OBSS) detection. In some aspects, a wireless station (STA) may identify one or more OBSSs based on wireless communications detected during an OBSS detection period and may roam to a new access point (AP) based on the identified OBSSs when a roaming condition is satisfied. In some implementations, the STA may store information associated with each identified OBSS in an OBSS table. When the roaming condition is satisfied, the STA may listen for beacon or probe response frames from other APs operating on its current wireless channel. If the STA receives beacon or probe response frames from one or more APs that match the OBSS table, the STA may roam to the matching AP with the highest candidate score.
