1. An apparatus comprising at least one processor, and at least one memory including a computer program code, wherein the at least one memory and the computer program code are configured, with the at least one processor, to cause the apparatus to:
receive a default time period, wherein the default time period is for allowing the apparatus to consider a request for leaving an active network connection to a first network as accepted by the first network if a response is not received, by the apparatus, from the first network within the default time period;
determine to leave the active network connection to the first network when having a connection that is idle or inactive to a second network simultaneously with the active connection to the first network;
transmit a first message, comprising a request regarding the determination to leave the active network connection, to an access node comprised in the first network;
receive, from the access node, a second message comprising an overriding condition for leaving that replaces the default time period for leaving the active network connection to the first network; and
leave the active network connection upon meeting the overriding condition for leaving, wherein the overriding condition for leaving, without receiving a third message, which is a message regarding the leaving, comprises a new time period for waiting before leaving, and a further condition for leaving, and the apparatus is caused to leave the active network connection at a time when either one happens first, or at a time when the new time period for leaving has passed and the further condition for leaving is met.
