Abstract:
1. A computer-implemented method comprising: at a component of a radio access network (RAN) configured for enhanced circuit switch fallback (eCSFB), wherein the RAN includes a plurality of paging zones that comprise one or more coverage areas, wherein the RAN is configured to send a given page type to non-CSFB devices via one or more first paging channels defined under a first air-interface protocol and to send the given page type to CSFB devices via one or more second paging channels defined under a second air-interface protocol, determining, for each of one or more of the paging zones, a respective measure of CSFB-device prevalence in the paging zone, wherein the respectively determined measure of CSFB-device prevalence for a given paging zone indicates a percentage of devices in the paging zone that are configured for CSFB; using the respectively determined measure of CSFB-device prevalence in at least one of the paging zones as a basis for determining one or more parameters for zone-based paging in the at least one of the paging zones; and applying the one or more determined parameters for zone-based paging in the at least one of the paging zones.
