1. A method performed by a radio access node of a Radio Access Network (RAN), the method comprising:
receiving data from a Core Network (CN) for a wireless terminal that is in a dormant state with respect to the RAN but for which the radio access node maintains control and user plane connections to the CN;
determining a RAN Area (RANA) to which the radio access node belongs;
identifying other radio access nodes that belong to the RANA; and
initiating paging of the wireless terminal in response to receiving the data from the CN, the paging initiated by the radio access node for the other radio access nodes.
