摘要
A method performed by a first network node of providing a last used PLMN ID in LTE to a second network node, the first network node and the second network node operating in a wireless communications network. The method comprises providing the last used PLMN ID in LTE of a wireless device in the wireless communications network, to the second network node, as soon as a Circuit Switched, CS, call due to a CSFB procedure has been setup. The providing of the PLMN ID is performed by one of: adding information about the last used PLMN ID in LTE to an existing message from the first network node to the second network node, and defining a new message from the first network node to the second network node. The new message comprises the last used PLMN ID in LTE.
