Claim Text:
1. A method, executed at a source base station, of determining a handover trigger for triggering handover of a mobile terminal in a wireless network from the source base station to a target base station, the method comprising: obtaining a first Key Performance Indicator (KPI) for each of a first candidate trigger and a second candidate trigger, wherein each first KPI indicates, for the corresponding candidate trigger, a quality of wireless services provided by the wireless network to the mobile terminal; obtaining a parameter associated with at least one of the mobile terminal and the wireless network, wherein the parameter indirectly or directly impacts handover performance; if the parameter passes a corresponding performance test, sending the first KPIs to the mobile terminal to facilitate a selection at the mobile terminal of one of the first and second candidate triggers as the handover trigger based on the first KPIs; and if the parameter fails the corresponding performance test, selecting one of the first and second candidate triggers as the handover trigger based on a first comparison between the first KPIs for the first and second candidate triggers; wherein obtaining the parameter comprises obtaining a speed of the mobile terminal; wherein the performance test comprises a speed threshold test; and wherein sending the first KPIs to the mobile terminal comprises sending the first KPIs to the mobile terminal to facilitate a selection of one of the first and second candidate triggers as the handover trigger if the obtained speed exceeds a speed threshold.
