We report here the results of 2 observations performed simultaneously with INTEGRAL, RXTE, the Ryle and Nancay radio telescopes. These observations belong to the so-called $\nu$ and $\lambda$ classes of variability during which a high level of correlated X-ray and radio variability is observed. We study the connection between the accretion processes seen in the X-rays, and the ejections seen in radio. By observing an ejection during class $\lambda$, we generalise the fact that the discrete ejections in GRS 1915+105 occur after sequences of soft X-ray dips/spikes. We then identify the most likely trigger of the ejection through a spectral approach to our INTEGRAL data. We show that each ejection is very probably the result of the ejection of a Comptonising medium responsible for the hard X-ray emission seen above 15 keV.
