Self organizing cellular networks
View Patent ↗This invention addresses a method of scanning and self organization that is programmed into the base station which then will automatically avoid mutual interference and move the use of radio channels from one base station to another to move network capacity to where it is needed through a process called “abandonment”.
1. A method for automatically organizing an interference avoiding radio frequency network of multiple base stations each capable of transmitting and receiving all channels of a radio frequency band and also having one or more sectors with each sector capable of transmitting and receiving multiple channels comprising:
turning on one base station of said multiple base stations;
then said base station scanning all channels with one sector of said one or more sectors;
then said base station categorizing some or all of said channels as do not use, share, or dominate wherein the do not use categorized channels are disabled, the share categorized channels are scanned, identified, and assigned if available, and the dominate categorized channels are never disabled;
then said base station identifying all available channels in said one sector that are not being used by another base station of said multiple base stations;
then said base station assigning available unused channels to said sector of said base station wherein the maximum number of available unused channels to assign is determined by dividing the number of channels of a radio frequency band capable of being transmitted and received by said base station by the number of said one or more sectors on said base station; and,
said base station then repeating the scanning, categorizing, identifying, and assigning of unused channels in each of the other sectors of said one or more sectors.
2. The method of claim 1 including disabling some or all unused channels.
3. The method of claim 2 including automatically disabling a channel if interference in said channel is detected by said base station.
