Optimized mechanism for paging transmission and reception

A method comprising:

• storing information of a paging area by a base station, wherein the paging area is a geographic area covered by a cluster of neighboring base stations, and wherein the paging area is a subset of a tracking area formed through the coordination among different base stations;
• storing a user equipment (UE) list;
• updating the UE list upon detecting one or more triggering events;
• and
• paging the UEs on the UE list repeatedly by the repetition number.

A user equipment (UE) comprising

• a transceiver that transmits and receives radio signals via a first radio access link;
• an information storage that stores information of a stored paging area, wherein the paging area is a subset of a tracking area formed through the coordination among different base stations;
• a paging area manager that receives information of a paging area from a base station when the UE, determines if there is one or more change between the paging area and the stored paging area of the UE, and notifies the base station if there is one or more paging area change;
• and
• a pager that receives and processes paging messages in the paging area, wherein the page messages are transmitted repeatedly by a repetition number.
