The invention provides a band dynamic selecting and time scheduling method in a
heterogeneous network, relating to a method and equipment for dynamically selecting
usable frequency resources in a plurality of main
system bands in a
heterogeneous network system based on the
cognitive technology, in particular to a method and equipment used for opportunity spectrum access, frequency resource efficient utilization, and combination of
heterogeneous network resource amalgamation and user business
service quality (QoS) assurance. The invention has the band dynamic selecting method as follows: firstly, aiming to different main
system characteristics, an average main system user
detection threshold of each main system of a
base station CBS accessory is defined and cognized, and the threshold is an average value of the prior
detection threshold in a
wireless network transmission environment; secondly, according to the average main system user
detection threshold and the
throughput needs of a secondary system user, scanning efficient time of CBS to each main system is defined; thirdly, the CBS selects the optimal main system band from a
usable band
list according to a request of a user, the
wireless transmission characteristics and a channel state of a band channel are the basis for selecting the optimal band, and interruption of the equipment CPE
transmission throughput is preset according to the user.
