  • OFDMA ASSISTED FAST ROAMING IN LABEL SWITCHED MOBILE NETWORKS
    Publication number: 20240073759
    Abstract: In one embodiment, a wireless access point receives, from a mobile system, a broadcast beacon that includes a roaming notification indicating that the mobile system intends to roam to the wireless access point. The wireless access point allocates, after receiving the broadcast beacon from the mobile system, an orthogonal frequency-division multiple access resource unit for use by the mobile system. The wireless access point sends a trigger message to the mobile system that includes an indication of the orthogonal frequency-division multiple access resource unit. The wireless access point performs, after sending the trigger message, a handoff exchange with the mobile system using the orthogonal frequency-division multiple access resource unit to attach the mobile system to the wireless access point.
