Abstract
Methods and apparatus for managing frequency reassignment within wireless access nodes so as to minimize data session disruption. In one embodiment, the frequency reassignments occur within a quasi-licensed system utilizing 3.5 GHz CBRS (Citizens Broadband Radio Service) spectrum, and a reassignment of wireless spectrum that mitigates disruption or loss of continuity to existing data sessions of users of devices associated with a CBSD/xNB is provided via notification of the associated devices (e.g., Category B Consumer Premises Equipment or CPE, such as an FWA) of the reassignment by the CBSD/xNB. In one variant, the associated devices are instructed by the CBSD/xNB to invoke a “wait and re-establish” protocol that obviates a full frequency band rescan in favor of a designated target frequency provided to the CBSD/xNB by the cognizant SAS or DP.
