METHOD FOR DYNAMIC CORDLESS CHANNEL ALLOCATION OF MOBILE COMMUNICATION SYSTEM

摘要

The purpose of the present invention is to provide a method for a dynamic wireless channel allocation service in a mobile communication system which can minimize frequency collisions between adjacent APs in a wireless network by providing a dynamic wireless channel allocation service in a mobile communication system, and can provide high speed Wi-Fi through even allocation to all channels. The method comprises: a first search step of searching for a wireless channel of an adjacent AP along a moving path of a mobile object in a wireless network; a second search step of searching for a channel band which does not overlap other channel bands among channel bands which are recommended by national guidelines by looking for an opportunity to use a channel band on the frequency band of the wireless channel of the searched AP in the first search; a step of assigning the searched channel band as a wireless channel of the mobile object when a channel band which does not overlap other channel bands has been found in the second search step; a third search step of searching for a channel band which does not overlap other channel bands among the channel bands recommended by national guidelines by looking for an opportunity to use a channel band on the frequency band of the wireless channel of the AP which is searched for again when a channel band which does not overlap other channel bands has not been found in the second search step; a step of assigning the searched channel band as a wireless channel of the mobile object when a channel band which is not being used is found in the third search step; a step of measuring transmission speeds and signal strength by looking for an opportunity to use a channel band on the entire frequency band of the wireless channel of the searched AP when a channel band which is not being used has not been found; and a step of selecting one channel band having the highest speed or the strongest signal strength as a result of the measurement, and assigning the channel band as a channel band of the mobile object.
