METHODS AND SYSTEM FOR DYNAMICALLY SWITCHING OFF/ON OF BASE STATIONS
First Claim
1. A method for dynamically switching at least a base station in ON/OFF mode in a cellular network, the method comprising:
- determining traffic load information of at least a capacity BS and at least a coverage BS;
exchanging the traffic load information with at least a neighboring coverage BS and at least a neighboring capacity BS;
determining at least a preferred capacity BS for one of a switched OFF mode and a switched ON mode, wherein the preferred capacity BS is one of the capacity BS and a neighboring capacity BS corresponding to the coverage BS; and
switching the preferred capacity BS in to one of the switched OFF mode and the switched ON mode;
wherein a master controller is capable of implementing at least a determining method for determining at least the preferred capacity BS for one of the switched OFF mode and the switched ON mode;
wherein a slave controller is capable of implementing at least a switching method for switching at least the preferred capacity BS in to one of the switched OFF mode and the switched ON mode to meet traffic load requirement of the cellular network; and
wherein coordinated multipoint (CoMP) information with at least one of the coverage BS, the capacity BS, and the neighboring coverage BS is used to determine the preferred capacity BS to be switched ON.

Abstract
Disclosed are methods and system for dynamically switching at least a base station in ON/OFF mode in a cellular network. The method comprises: determining traffic load information of BSs; exchanging the traffic load information between BSs; determining at least a preferred BS for one of a switched OFF mode and a switched ON mode. The system comprises: at least a coverage BS with a master controller; at least a capacity BS with a slave controller adapted to be in one of the switched ON mode and the switched OFF mode depending on network conditions and to satisfy cellular traffic loads, and at least a communication interface adapted to provide interface between at least the coverage BS and the capacity BS.
