Adjustment of zone-based paging based on the prevalence of eCSFB devices

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 respective measure of CSFB-device prevalence for a given paging zone comprises a number of CSFB devices that are 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.

A non-transitory computer readable medium having stored therein instructions that are executable to cause at least one component of a radio access network (RAN) to perform functions comprising:

• determining, for each of one or more paging zones of the RAN, a respective measure of enhanced circuit switch fallback (eCSFB) device prevalence in the paging zone, wherein the RAN is configured for eCSFB and includes a plurality of paging zones that each comprise one or more coverage areas, and 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, 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 measures 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.

A radio-access-network (RAN) component comprising:

• a non-transitory computer readable medium;
• program instructions stored on the non-transitory computer readable medium an executable by at least one processor to:
• (a) determine, for each of one or more paging zones of the RAN, a respective measure of enhanced circuit switch fallback (eCSFB) device prevalence in the paging zone, wherein the RAN is configured for eCSFB and includes a plurality of paging zones that each comprise one or more coverage areas, and 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, wherein the respectively determined measure of eCSFB-device prevalence for a given paging zone indicates a percentage of devices in the paging zone that are configured for eCSFB;
• (b) use the respectively determined measure of CSFB-device prevalence in at least one of the paging zones as a basis to determine one or more parameters for zone-based paging in the at least one of the paging zones;
• and
• (c) apply the one or more determined parameters for zone-based paging in the at least one of the paging zones.
