<p>A method of identifying femto base station handover targets for user equipment in a wireless communications network, a computer program product and a femto base station gateway are disclosed. The method comprises the steps of: storing location history information identifying femto base stations previously visited by user equipment; receiving an indicator from user equipment identifying a detected femto base station as a handover target; and correlating said indicator against said location history information for that user equipment to identify those femto base stations hdving that indicator which have previously been visited by that user equipment as handover candidates. By using information identifying previously visited base stations, the number of potential handover targets can be dramatically reduced which in turn reduces the likelihood of an unsuccessful handover occurring and reduces the number of femto base stations which need to be unnecessarily prepared.</p> |
