Abstract
The present invention relates to a method of supporting proper hand-off of a dual-mode mobile terminal based on terminal capability and communication status to guarantee continuous mobility in a mixed communication network where a synchronous and an asynchronous network system coexist. According to the present invention, a dual-mode terminal transmits information of its terminal capability operable in both the synchronous and the asynchronous network system to the mixed communication network, irrespective of which network system a present service area belongs to, then the mixed communication network constructs information on adjacent cells, which are selectively included based on the received terminal capability information, of the other network system and provides the dual-mode terminal with the constructed adjacent cell information.
