Abstract
A presence service can be provided by an access pointserving a small cellby rejecting a request for registration from a user equipmentafter acquiring its IMSI and sending the IMSI to a presence database. The user equipment determines if the cell is a presence cell by comparing the cell's location area code (LAC) with LACs stored in a list and looking for a match. It the cell is a presence cell then the user equipment, rather than placing the LAC in a forbidden list, re-tries registration again but only after a pre-set time period of 5-10 minutes has elapsed. This has the advantage that a presence service can be notified of subscribers who linger in a particular area or return to that area at regular intervals.
