1. A method, comprising:
- detecting a sleeping cell at an access node;
modifying at least one coverage area of the access node to compensate for lost coverage in the sleeping cell, wherein the access node implements resource allocation algorithms; and
instructing the resource allocation algorithms to perform one of a plurality of predetermined actions concurrently with said modification depending on whether at least one quality of experience (QoE) is being met for at least one user.

Abstract
The present invention provides a method of coordinating access nodes when a sleeping cell is detected. The method may include modifying a coverage area of an access node to compensate for lost coverage in a sleeping cell detected by the access node. The access node implements resource allocation algorithms and a cell identification algorithm. The method may also include instructing the resource allocation algorithms and/or the cell identification algorithm to perform a predetermined action concurrently with the modification.

12. A method, comprising:
-
detecting a sleeping cell at an access node, wherein the access node implements a load-balancing algorithm; modifying at least one coverage area of the access node to compensate for lost coverage in the sleeping cell; and instructing the load-balancing algorithm to load balance traffic away from the access node concurrently with said modification, wherein instructing the load-balancing algorithm to load balance traffic away from the access node comprises determining whether to perform load balancing on at least one user based on at least one measured quality of experience (QoE) for said at least one user and at least one likelihood that a target QoE for said at least one user will be met after load-balancing. - View Dependent Claims (13, 14, 15)
