1. A data modulation method, applied to a service node, comprising:
determining a modulation parameter A according to a modulation manner of data; and
modulating the data according to a target constellation point symbol, wherein the target constellation point symbol is a product of A and X, and X is an initial constellation point symbol corresponding to the modulation manner;
wherein the modulation parameter A has a modulus value P, and modulation parameters A respectively corresponding to different modulation manners have different modulus values P; and
the different modulus values P of the modulation parameters A respectively corresponding to the different modulation manners are all ranged in (0,1].
