Method for operating a wireless radio network and a network

摘要

For allowing a particularly economic operation of a network with a high degree of energy conservation a method for operating a wireless radio network, especially a radio access network, is claimed, wherein the wireless radio network includes a core network, a number of base stations and at least one mobile host for wireless communication via at least one base station, wherein the method is characterized in that an association of powered on and powered off base stations within definable base station partitions will be arranged in a coordinated manner, thereby maintaining a minimum number or the smallest possible number of powered on base stations being necessary for accommodating a current traffic demand. Further, a network is claimed, preferably for carrying out the above mentioned method.

主权项

1. A method for operating a wireless radio network, wherein the wireless radio network is comprising a core network, a number of base stations and at least one mobile host for wireless communication via at least one base station, comprising the steps of:
where a peak traffic configuration is defined as where all the base stations of the wireless radio network are powered on, during an off-peak traffic configuration, defining base station partitions where a base station partition is an association of powered on and powered off base stations where each powered on base station can cover regions of prior powered on base stations; within the created base station partitions, maintaining a minimum number or smallest possible number of powered on base stations being necessary for accommodating a current traffic demand, with all remaining base stations within each partition not being necessary for accommodating the current traffic demand being powered off; and once the base station partitions are created, when load conditions or mobility among neighbouring partitions change, performing a re-arrangement of the base station partitions by changing the association between the powered on and the powered off base stations, wherein a functionality of one powered on base station of a first partition is moved towards another base station of a neighbouring second partition with a lower load.
