1. A method for initiating a connection to a target wireless communications network carried out by a wireless communications device comprising:
camping in an idle mode or an inactive mode, on a first cell of a first wireless communications network;
receiving a paging message containing specified network characteristics or an indication of specified network characteristics to be used by the wireless communications device in connecting to the target wireless communications network, wherein the specified network characteristics include a radio access technology (RAT);
determining whether or not the wireless communications device can initiate a connection to the target wireless communications network on the first cell using the RAT included in the specified network characteristics;
upon determining that the wireless communications device cannot initiate the connection to the target wireless communications network on the first cell using the RAT included in the specified network characteristics, performing a cell re-selection to a second cell to match the specified network characteristics; and
initiating a connection to the target wireless communications network using the specified network characteristics over the second cell of the target wireless communications network, based on the specified network characteristics, wherein the target wireless communications network is one of the first wireless communications network or a second wireless communications network.
