1. A method, comprising:
based on a first location in a geographic area of a signal measurement of a first carrier signal measured by a user equipment in an idle mode, and a transmission location of a carrier signal source of the first carrier signal, estimating, by a system comprising a processor, an estimated first path loss value of the first carrier signal, wherein the signal measurement comprises characteristics of the first carrier signal measured by the user equipment while the user equipment was in the idle mode, wherein the signal measurement was stored at the user equipment and communicated based on an interval selected to manage a battery power of the user equipment, wherein the signal measurement was communicated as an appended portion of a mobility management message, wherein the appended portion was appended to the mobility management message by the user equipment, wherein the mobility management message comprises a tracking area update message, and wherein the interval was selected based on a selected frequency of signal measurements;
based on the estimated first path loss value and a second path loss value of a second carrier signal received from the carrier signal source at a second location, determining, by the system, an antenna pattern of the carrier signal source; and
based on the antenna pattern, generating, by the system, a propagation model for the carrier signal source within the geographic area.
