Method for transmitting data in a radio communication network

A radio communications system, comprising:

• serving radio network controllers;
• a controlling radio network controller in communication with the serving radio network controllers;
• base stations in communication with the controlling radio controller;
• a plurality of subscriber stations using a shared channel for exchanging data with a base station among the base stations, each subscriber station being configurable based on a message received from one of serving radio network controllers,
• wherein a base station sends a first message to the controlling radio network controller when a transmission quality measured in the subscriber stations and made available to the base station of at least one of the plurality of subscriber stations exchanging data with the base station does not meet a defined criterion, the first message containing information about the transmission quality and about the at least one subscriber station, and
• wherein the measurements of transmission quality are based on at least one of a transmission rate via the shared channel and determining a ratio of a number of elapsed timers relative to a total number of allocated timers.

A method for transmitting data in a radio communications system in which a plurality of subscriber stations use a shared channel for exchanging data with a base station, comprising:

• measuring a transmission quality of the shared channel for each of the subscriber stations in the subscriber stations;
• transmitting the measured transmission quality to the base station;
• and
• transmitting a first message from the base station to a controlling radio network controller controlling the base station when transmission quality based on one of a transmission rate and a ratio of a number of elapsed timers relative to a total number of allocated timers of at least one of the subscriber stations is inadequate, the first message containing information about the measured transmission quality of the at least one subscriber station with inadequate transmission quality.
