1. An apparatus in a communications device supporting a plurality of different identities, the apparatus comprising at least one processor and at least one memory including computer program code, the at least one memory and computer program code configured to, with the at least one processor, cause the apparatus at least to:
determine at least one paging overlap occasion for networks associated with the different identities;
communicate the at least one paging overlap occasion determination to one of the networks associated with one of the different identities within a registration request to the one of the networks, wherein the one of the networks is caused to schedule at least one paging message to the apparatus based on the at least one paging overlap occasion determination such that the at least one paging message is scheduled at a time other than the at least one paging overlap occasion determination; and
control a reception of the at least one paging message for the one of the networks such that the apparatus is caused not to listen for a paging message for the one of the networks during the determined at least one paging overlap occasion and control a reception of at least one paging message for a further one of the networks associated with the different identities during the determined at least one paging overlap occasion,
wherein communicating the at least one paging overlap occasion determination to one of the networks associated with the different identities within a registration request to the one of the networks further comprises communicating the at least one paging overlap occasion determination to one of the networks within at least one paging assistance information element,
wherein the at least one paging assistance information element comprises:
a definition of overlapping paging frames;
a system frame number from which the paging overlap window starts;
a paging overlap index identifying a first slot/symbol of the paging overlap; and
a paging overlap length identifying a number of consecutive slot/symbols of the paging overlap,
wherein the identities comprise a universal subscriber identity module identity; an electronic subscriber identity module identity; and a subscriber identity module identity.
