Abstract

The invention relates to a method for using a user equipment with a mobilecommunication network and/or for an energy-saving operation of the user equipment with the mobile communication network, wherein the mobile communication network provides communication services to the user equipment using a radio access network that serves or provides radio coverage to the user equipment,wherein at least a part of the radio access network corresponds to a terrestrial radio access network that provides radio access network functionality to the user equipment, wherein additional, or complemental, radio access network functionality is able to be provided, to the user equipment, by means of a non-terrestrial radio access network, wherein the user equipment is able to switch or to be switched from being provided with radio access network functionality either by means of the terrestrial radio access network or by means of the non-terrestrial radio access network,wherein, in order to use or to operate the user equipment in a situation of low or inexistent radio access network functionality being provided or able to be provided by means of the terrestrial radio access network, the method comprises the following step:-- in a first step, the user equipment is served by the terrestrial radio access network and detects a loss of radio coverage provided by the terrestrial radio access network,-- in a second step, the user equipment applies a delay time interval prior to initiating a cell selection procedure at least with regard to the non-terrestrial radio access network,-- in a third step,-- in case that loss of radio coverage provided by the terrestrial radio access network is still detected upon expiry of the delay time interval, the user equipment initiates a cell selection procedure with regard to the non-terrestrial radio access network, and alternatively,-- in case that the user equipment regains radio coverage provided by the terrestrial radio access network, the user equipment continues to be served by the terrestrial radio access network.
