SYSTEM AND METHOD TO USE WIFI AS BACKUP FOR CBRS PRIVATE 5G NETWORK

Abstract: systems and methods to use wi-fi as backup for cbrs private 5g network. one such method includes: using access traffic steering, switching and splitting (atsss) user equipment route selection policy (ursp) to map a first portion of traffic to 3gpp citizens broadband radio service (cbrs) 5g access and to map a second portion of traffic to non-3gpp wi-fi access; creating a multi-access protocol data unit (ma-pdu) session using atsss between a user plane function (upf) and user equipment (ue) through the 3gpp cbrs 5g access and the non-3gpp wi-fi access; implementing atsss load balancing to control traffic congestion between the 3gpp cbrs 5g access and the non-3gpp wi-fi access; and initiating one of a plurality of atsss steering modes to define a primary access network and a backup access network, wherein, in response to the primary access network becoming unavailable, the system automatically switches to the backup access network.
