Method for hand-over of terminal, network element, base station, and communication system
Abstract:
The invention provides a method for hand-over of a terminal from a first base station to a second base station, radio network element, terminal, base station and a communication system. The method for hand-over of a terminal from a first base station to a second base station, wherein said first base station is EV-DO enabled in an access network and said second base station is not EV-DO enabled, said method comprising: transmitting an EV-DO pilot signal from said second base station to said terminal; sending a route update message including an EV-DO pilot strength from said terminal if said EV-DO pilot strength is above a predetermined threshold; calculating a CDMA pilot strength based on said EV-DO pilot strength; and performing the hand-over of said terminal to said second base station when CDMA pilot strength is above the hand-over threshold.
