A method of providing telecommunications network radio coverage in a region, the method including: providing a plurality of associated access points (AP1-AP6); and performing a configuration procedure by: causing one or more of the plurality of access points to transmit in turn whilst the others of said access points are caused to receive only and to measure the received signal at each of the other of the access points, calculating the optimum parameters for each of said access points on the basis of the measurements, configuring each of said access points in accordance with the calculated parameters; and the method characterised by: defining the plurality of access points as a cluster; designating at least one of said access points located near the edge of said region as a gateway access point, setting parameters of the plurality of associated access points, so that a mobile terminal registered with an access point of the cluster can only handover or reselect to a base station external to the cluster, when registered with a gateway access point. providing a plurality of associated access points (AP1-AP6); and performing a configuration procedure by: causing one or more of the plurality of access points to transmit in turn whilst the others of said access points are caused to receive only and to measure the received signal at each of the other of the access points, calculating the optimum parameters for each of said access points on the basis of the measurements, configuring each of said access points in accordance with the calculated parameters; and the method characterised by: defining the plurality of access points as a cluster; designating at least one of said access points located near the edge of said region as a gateway access point, setting parameters of the plurality of associated access points, so that a mobile terminal registered with an access point of the cluster can only handover or reselect to a base station external to the cluster, when registered with a gateway access point. causing one or more of the plurality of access points to transmit in turn whilst the others of said access points are caused to receive only and to measure the received signal at each of the other of the access points, calculating the optimum parameters for each of said access points on the basis of the measurements, configuring each of said access points in accordance with the calculated parameters; and the method characterised by: defining the plurality of access points as a cluster; designating at least one of said access points located near the edge of said region as a gateway access point, setting parameters of the plurality of associated access points, so that a mobile terminal registered with an access point of the cluster can only handover or reselect to a base station external to the cluster, when registered with a gateway access point. defining the plurality of access points as a cluster; designating at least one of said access points located near the edge of said region as a gateway access point, setting parameters of the plurality of associated access points, so that a mobile terminal registered with an access point of the cluster can only handover or reselect to a base station external to the cluster, when registered with a gateway access point.
