The method according to claim 1 , wherein the mobility information comprises one or more radio quality related parameters, and wherein the one or more radio quality related parameters comprises one or more of: a Reference Signals Received Power, RSRP, a Reference Signal Received Quality, RSRQ, a Signal to Interference plus Noise Ratio, SINR, a list of one or more cells, a list of one or more beams, a list of one or more Reference Signals, RS, type coverage the UE is moving to, time information wherein the RSRP, RSRQ and SINR are for a frequency and in different levels of granularities.
4. The method according to claim 1 , wherein the predicted mobility information is comprised in a measurement report when being reported to the first network node.
5. The method according to claim 1 , wherein the predicted mobility information is reported when the UE is in connected state.
6. The method according to claim 1 , comprising:
obtaining a prediction model from the first network node, wherein the prediction model indicates how to perform the prediction of the mobility information; and

wherein the prediction model is an updated prediction model that replaces a previously obtained prediction model.
8. The method according to claim 1 , comprising:
receiving network node information for network nodes associated with the UE; and
reporting the received network node information to the first network node.
9. The method according to claim 1 , wherein the prediction of the mobility information is based one or more input parameters, and
wherein the one or more input parameters are at least one of: network node information, sensor information, UE connection parameters, mobility history parameters and time information.
10. A method performed by a first network node for handling mobility information in a communications network, the method comprising:
obtaining predicted mobility information from a User Equipment, UE, which UE the first network node currently serves, wherein the mobility information is associated with a mobility procedure wherein the mobility procedure is a conditional handover;
based on the predicted mobility information, determining to:
initiate a mobility procedure associated with the UE; and
initiating the mobility procedure.
11. The method according to claim 10 , wherein the predicted mobility information is obtained periodically or when triggered by a measurement event.
12. The method according to claim 10 , comprising:
obtaining, from the UE, network node information for network nodes associated with the UE.
