Embodiment Construction

[0025] first reference figure 1 , figure 1 A first radio access system 2 operating according to the GSM standard and a second radio access system 4 using code division multiple access are represented. For clarity, radio access systems are shown covering contiguous areas. In practice, the two radio access systems may partially or completely overlap. The area covered by each radio access system is divided into a number of cells 6 and 8, respectively. The cells of the respective radio access systems may have the same or different boundaries where there is an overlap between the radio access systems. Each cell 6 and 8 is served by a corresponding base station 10 . Base stations are each arranged to communicate with mobile stations 12 or other suitable terminals.

[0026] The base stations 10 of the GSM radio access system are arranged to be controlled by respective base station controllers 14 . exist figure 1 In the example shown in , each base station controller 14 is arra...

Abstract

A communication system, said system arranged to provide communication coverage over an area, said system comprising a plurality of first means, each of said first means controlling at least one parameter and / or configuration setting with respect to an area smaller than said coverage area and second means for receiving information from a plurality of said plurality of first means and for controlling at least one parameter and / or configuration setting with respect to the area associated with at least one of said plurality of said plurality of first means.

Description

technical field [0001] The present invention relates to communication systems. Background technique [0002] In a typical cellular radio network, the area covered by the network is divided into a number of cells. Each cell is served by a base transceiver station that transmits signals to and receives signals from terminals located in the corresponding cell associated with a particular base transceiver station. A terminal may be a mobile station capable of moving between cells. [0003] In current networks, radio resources (and any other network resources) are usually managed in a distributed fashion. In particular, it is the responsibility of the controller of the base station to control the resources of its own base station. In the GSM (Global System for Mobile Communications) standard, a Base Station Controller (BSC) is arranged to control a group of base stations. In proposed third generation systems utilizing CDMA (Code Division Multiple Access), a Radio Network Cont...
