The present invention relates to a method and system for enabling a redistribution of load between cells. The method comprises obtaining a current load value for a first cell, and obtaining a target load value for a neighbor cell. The method also comprises determining the target load value for the first cell as a function of the current load value and the target load value for the neighbor cell, obtaining an update of the target load value for the neighbor cell, and iterating the determining and the obtaining. The method further comprises taking action for a redistribution of load between the first cell and the neighbor cell towards a load distribution represented by the resulting load values.

Methods, nodes and system for enabling redistribution of cell load

A method of tracking user terminals in a mobile communication network includes, at a tracking node, determining that a user terminal is located in a first tracking area, storing data associated with the first tracking area, the data comprising a number of observations of all user terminals at the first tracking area at a first time, receiving a page response from the user terminal located in one of the first tracking area and a second tracking area, and in an event that the user terminal remains located at the first tracking area, updating the data to include a number of page responses received at the first tracking area after a first time interval, and in an event that the user terminal is located at the second tracking area, updating the data to include a number of page responses received at the second tracking area after the first time interval.
