Claim:
A handover control method carried out at a mobile station for switching a destination base station in a multi-hop network including base stations and mobile terminals wherein neighboring base stations are arranged at a shorter interval than a range in which a wireless communication signal is available to enable wireless communication to take place between the neighboring base stations, said handover method comprising: a reception step of receiving at the mobile station the communication signal transmitted from a prospective base station including identification information of the prospective base station and information of neighboring base stations existing in a surrounding area of the prospective base station; a listing step of making a list of the neighboring base stations represented by the information of neighboring base stations; and a control step of controlling handover processing on a basis of the identification information and the information of neighboring base stations received at said reception step; said control step comprising: a present destination decision step of deciding a current destination base station connected with at present; a switching decision step of using the information of the neighboring base stations to decide whether or not the destination base station is to be switched over; and a switching step of switching over the destination base station on the basis of the decision result of said switching decision step said switching decision step comprising: a base station identity decision step of using the communication signal to decide whether or not the prospective base station that has transmitted the communication signal received at said reception step is the same as the current destination base station, wherein, when said base station identity decision step decides that the prospective base station that has transmitted the communication signal received at said reception step is not the same as the current destination base station, consecutively said switching decision step decides whether or not the current destination base station is included in the list, if the current destination base station is not included in the list, then said switching decision step deciding that the destination base station is to be switched over from the current destination base station to the prospective base station that has transmitted the communication signal received at said reception step.
