1. A method comprising:

  • receiving, by one or more processors, a request regarding a location of a user equipment (UE) device, wherein receiving the request triggers the one or more processors to select for use by the UE device a signal scanning rate and a signal scan reporting rate;

    storing, by a data storage device accessible to the one or more processors, a data structure containing a plurality of signal scan reporting rates, wherein each of the signal scan reporting rates is associated with a UE device speed value and a base station density value;

    receiving, by the one or more processors, frequency band data pertaining to a location of the UE device, wherein the frequency band data indicates two or more frequency bands available for use by the UE device while the UE device is at or in proximity to the location, and for each frequency band of the two or more frequency bands a respective radio access technology used at that frequency band of the two or more frequency bands, and wherein one of the two or more frequency bands is the frequency band a base station is using to serve the UE device;

    selecting, by the one or more processors and from among the plurality of signal scan reporting rates, a signal scan reporting rate for use by the UE device based on a UE device speed value determined based on a speed of the UE device and a base station density value determined for an area in proximity to the location of the UE device;

    selecting, by the one or more processors and from among the plurality of signal scanning rates, a signal scanning rate for use by the UE device to scan for signals on at least one frequency band other than a frequency band the base station is using to serve the UE device, wherein selecting the signal scanning rate is based on the selected signal scan reporting rate, the determined UE device speed value, and the determined base station density value; and

    providing, using a communication network, the selected signal scanning rate and the selected signal scan reporting rate to a transmitting device for wireless transmission of the selected signal scanning rate and the selected signal scan reporting rate to the UE device.
