Network elements, wireless communication system and methods therefor

A method for providing a location presence service in a cellular communication system comprising a plurality of neighbouring small cells including a presence cell and a cluster of cells, the method comprising:

• assigning an area code to the presence cell which is different from an area code assigned to a neighbouring macrocell;
• assigning an area code to each cell in the cluster of cells which is the same as the area code of the macrocell;
• receiving at the presence cell, from a wireless communication unit, a registration request and an identity of the wireless communication unit;
• rejecting the registration request;
• transmitting periodically, in each cell included in the cluster of cells, a first paging message containing an identity of the wireless communication unit;
• receiving from the wireless communication unit at a first cell included in the cluster of cells, a first paging message acknowledgement;
• and
• in response, generating a first presence message wherein the first presence message includes an identity of the wireless communication unit and an estimated location of the wireless communication unit.
