Adjustment of communication parameters in a coverage area based on prevalence of eCSFB devices in the coverage area

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 a measure of circuit switch fallback (CSFB) device prevalence in a coverage area, wherein the RAN is configured to use a first channel defined under a first air-interface protocol for a given type of communication with non-CSFB devices, and wherein the RAN is further configured to use a second channel defined under a second air-interface protocol for the given type of communication with CSFB devices;
• using the measure of CSFB-device prevalence in the coverage area as a basis for adjusting one or more parameters for communications via the first channel;
• and
• applying the one or more adjusted parameters to communications with devices via the first channel that is defined under the first air-interface protocol.

A radio-access-network 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 a measure of circuit switch fallback (CSFB) device prevalence in a coverage area, wherein the RAN is configured to use a first channel defined under a first air-interface protocol for a given type of communication with non-CSFB devices, and wherein the RAN is further configured to use a second channel defined under a second air-interface protocol for the given type of communication with CSFB devices;
• (b) use the measure of CSFB-device prevalence in the coverage area as a basis to adjust one or more parameters for communications via the first channel;
• and
• (c) apply the one or more adjusted parameters to communications with devices via the first channel that is defined under the first air-interface protocol.

A computer-implemented method comprising:

• a radio access network (RAN) determining a measure of enhanced circuit switch fallback (eCSFB) device prevalence in a coverage area, wherein the RAN is configured to use a first channel defined under a first air-interface protocol for a given type of communication with non-eCSFB devices, and wherein the RAN is further configured to use a second channel defined under a second air-interface protocol for the given type of communication with eCSFB devices;
• using the measure of eCSFB-device prevalence in the coverage area as a basis for adjusting one or more parameters for communications via the first channel;
• and
• applying the one or more adjusted parameters to communications with devices via the first channel.
