WIRELESS COMMUNICATION METHOD

PROBLEM TO BE SOLVED: To reduce a restart time for transmission of forward link data by allowing a main base station to use a fundamental channel or a sub channel and deciding whether or not the forward link data are to be sent via an air interface. SOLUTION: When receiving forward link user data from a sub channel(SCH) distribution function, a main leg assigns a sub channel resource to the data, communicates an air interface channel parameter at an assigned SCH fast data rate to a mobile station 412 by using an F-fundamental channel(FCH) and transmits the data to the mobile station by using the F-SCH. However, when many data are not present, other system is employed, a few F-SCH resources are not assigned, and a forward FCH(F-FCH) air interface resource having already been assigned is used to process a data message. The main base station uses the fundamental channel or the sub channel to decide whether or not the forward link data are sent via an air interface.
