METHODS TO CONTROL THE LOADING OF AN UPLINK LINE IN A MOBILE RADIO NETWORK
Considered the functions for the control of cells load used on real networks of WCDMA technology, including: Potential User Control, Intelligent Access Control, Call Admission Control, Inter-Frequency Load Balancing Based on Configurable Load Threshold, Intra-frequency Load Balancing, Load Reshuffling, Overload Control. The basic parameters measured by means of a Base Station and Radio Network Controller for the cell load testing are considered. Examples are offered for the characteristics of the load. It is shown that the uplink operating load level is one of the main factors for the application of control algorithms. The issues of measurement results processing are discussed. Proposed and reviewed in detail the automatic adaptive algorithm update of background noise, ensuring its limitation in changing environmental conditions. The promising directions for further development of the proposed approach are identified.
