Abstract:
1. A method for distributing mobile stations between load monitoring areas, where the mobile stations are in a state where each mobile station selects a cell to receive service based on one or more parameters provided by one or both of a first broadcast message in a cell in a first load monitoring area or a second broadcast message in a cell in a second load monitoring area, comprising: determining a load of the first load monitoring area where the mobile stations are currently camped, and to reduce the load in the first load monitoring area, instructing adjustment of one or more parameters in one or both of the broadcast messages in order to steer one or more of the mobile stations to camp on the second load monitoring area, wherein the one or more parameters includes an offset parameter determined based on a difference between the loads in the first load monitoring area and the second load monitoring area, wherein the offset parameter is added to or subtracted from a signal measurement made by the mobile station for a cell selection procedure or cell re-selection procedure so that by adjusting the offset parameter, one or more of the mobile stations is steered away from the first load monitoring area and steered to camp on the second load monitoring area, and wherein the offset is determined in accordance with one of the following equations (1)–(4): wherein T
