A method and apparatus for redirecting a wireless communication unit () from a LTE cell to a neighboring 3G or 2G cell for the purposes of performing a procedure which is available in the 2G or 3G cell but not available in the LTE cell includes the provision of an additional LTE access point () within the coverage area of an LTE macrocell. The additional LTE access point () is arranged to capture a wireless communication unit () which is camped onto the LTE macrocell and redirect it to a 3G/2G cell irrespective of whether or not a better service may be provided in the 2G/3G cell. The invention has application to presence detection where collection of wireless communication units' and subscribers' IDs for such a purpose is possible in 3G and 2G cells but not in LTE cells.

Network elements, wireless communication system and methods therefor

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.

Wireless communication unit, access point and method for providing a presence service in a wireless communication system

A network management system for managing communications in a cellular communication network comprising an access point operably coupled to an access controller. The network management system comprises an access controller configuration logic module arranged to configure the access controller with configuration information. The network management system further comprises an access point configuration logic module arranged to configure the access point with configuration information comprising, at least in part, configuration information intended for the access controller.
