Abstract: There is provided a method of initiating a search for a home network in a mobile device that is attached to a network other than a home network of the mobile device, the method in an apparatus comprising determining whether the mobile device is in a part of said other network where there may be coverage from the home network; and if the mobile device is determined to be in a part of said other network where there may be coverage from the home network, sending a message to said other network in order to change one or more of a voice, messaging and/or data service available to the mobile device, such that the mobile device can enter an idle state and perform a search for the home network.

Abstract: There is provided a method of initiating a network re-attachment procedure by a mobile device, the mobile device being attached to a network other than the home network of the mobile device, and wherein location information for the mobile device in said other network is stored in a visitor location register, VLR, in said other network, the method comprising transmitting a first signal between the home network and the mobile device, if the home network and/or the mobile device is aware that the mobile device is in a border cell of the visited network where there may or should be coverage from the home network. This first signal indicates that the network re-attachment procedure can be initiated, since it has been determined that the mobile device is in said border cell, the mobile device, when sending or receiving said first signal starts a timer.
