Abstract
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.
