The idea is that it would be similar to the way that photons mediate the effect of the electromagnetic field. Though I've personally always thought that this description wasn't too good at explaining large gradual changes in the electromagnetic field, similar to how gravitons are a bit of weird model for the large gradual curvature of spacetime (it's not that it can be done but it is a bit awkward). Anyway the most straightforward way to implement gravitons in this sense doesn't pan out mathematically so we're not even sure if this model is at all accurate.
