1. An apparatus, comprising:
at least one processor; and
at least one memory including computer program code,
wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus at least to
determine a number of cell changes of a user equipment;
estimate a mobility state of the user equipment associated with a network;
determine at least one scaling factor; and
scale the mobility state estimate, which is based on the number of cell changes of the user equipment, according to the at least one scaling factor,
wherein the mobility state estimate is based on the number of cell changes of the user equipment, and the at least one scaling factor is determined based on discontinuous reception during a period of the estimation.
