The invention relates to a method for a radio communication mobile device to implement cell selection with multi-band multi-access technology, comprising the steps of after starting the mobile device, confirming priority for band measurement according to information acquired from storage equipment, such as access technology selected by a user, a cell residence history table and a neighbor cell history table; confirming primary cell list of cell selection according to an indicated value of signal intensity of band measurement with highest priority, an intensity value of pilot channel, and carrier-to-interference ratio of pilot channel; confirming a cell selection list combined with the cell residence history table and the neighbor cell history table; the mobile device resides on the cell with the highest priority in the cell selection list. With the implement method of cell selection with multi-band multi-access technology for the radio communication mobile device, mobile device can reside cells fast, which reduces measurement number of frequency point effectively and reduces operation time, reduces power consumption of the system, and is capable of locating the service cells more accurately, and enhances efficiency of initial residence of cells.
