Embodiment Construction

[0018] The present invention relates to a method of assigning optimum system control parameters to mobile stations in a cellular communication system. According to an aspect of the invention, the method includes applying a reference frame, such as a grid, to the coverage area of ​​the communication system independently of the transceiver. Each area bounded by the reference frame is assigned a code corresponding to a system control parameter. This system control parameter may be a neighbor list of handover candidates, a handover timer, a handover threshold, or a power control threshold. When the mobile station is positioned within an area defined by the reference frame, the mobile station is provided with system control parameters optimized for that area.

[0019] According to another aspect of the present invention, a method of assigning optimal system control parameters to a mobile station is provided. The coverage area of ​​a communication system is divided into defined ge...

Abstract

The present invention discloses a method for allocating optimal system control parameters in a wireless communication system (10) having one or more transceivers (11a)-(11g), the method comprising: assigning a plurality of regions (16) - The frame of reference (14) of (20) applies to the coverage area of ​​the communication system (10). The reference frame (14) is independent of the location of the one or more transceivers (11a)-(11g), and each of the plurality of areas (16)-(20) corresponds to a location estimate. Each of said plurality of areas (16)-(20) is assigned a code corresponding to a system control parameter optimized for that area. A code corresponding to where the mobile station (12) is located is assigned to the mobile station (12).

Description

technical field [0001] The present invention relates generally to cellular communication systems and, in particular, to a method and apparatus for assigning system control parameters to mobile stations. Background technique [0002] In all cellular systems, mobile stations need to frequently receive neighbor list assignments to switch between one base station and another when the mobile station moves out of range of a cell and into range of a new cell. However, there is a great deal of uncertainty as to which cell the cell will come into and which base station will best serve the mobile station. The neighbor list facilitates handover by providing candidate cells to the mobile station. That is, these cells can become serving cells for mobile stations. [0003] The current neighborhood list is determined based on various inputs, ranging from path loss predictions to field measurements, and may also include intuitions of parts of the system or maintenance engineer intuitions....
