Telefónica Germany introduces self organizing network

Telefónica Germany announced the introduction of self organizing network (SON). The new technology should adjust independently, promptly and flexibly the mobile network of the company to changing local conditions. The self tuning network can play out its strengths in the current integration of networks of o2 and E-Plus and promises for an improved user experience, as the company also in one tells blog .

the self organizing network to ensure in future in the common network of Telefónica Germany that loads in the 2 g 3 g and 4 g network dynamically controlled, congestion can be reduced and the temporary loss of a mobile radio station automatically improves coverage gaps. What was possible only through the manual change of parameters by technicians, take care of the SON software naturally, so Telefónica. To gather, analyze, and she continuously optimize a variety of parameters in the network. The current network data are collected at relatively short intervals, examines, and played back with adjustments in the network, as the company further. The necessary SON modules will be introduced gradually into the network of Telefónica Deutschland.

“The implementation of self organizing networks is Telefónica Germany of one of the global leaders”, Cayetano Carbajo Martin, Chief Technology Officer of Telefónica Deutschland says. “The way in which we use this technology, is unique. It allows us not only the fully automatic optimization, but also a simplified integration of new mobile radio system. With the software we will can better optimize our network and at any time automatically and flexibly the actual customer benefits fit.” “

in a first step, Telefónica Germany has introduced the self organizing network for the optimization of relations between neighboring mobile base stations in the UMTS network – the so-called neighborhood planning and maintenance. Already in the year 2014, the company has started to test the automatic neighborhood planning by various SON manufacturers in the framework of pilot projects in Berlin and Nuremberg. After the success of these tests was according to Telefónica now the final commissioning of the self organizing networks in Germany.

more modules, overloads, failures or overreach identify and can respond almost in real time, are planned according to the company. Already a load distribution is active, move the customers of impending overload within a LTE radio cell without sacrificing performance on UMTS. The Smartphones should self return to LTE, as soon as the technology is free and available.

straight through the ongoing consolidation work of the networks of O2 and E-plus the new network of Telefónica Deutschland is located in constant change. Any changes must be kept to permanently in the settings of the network. In view of the magnitude of this project, this represents a very elaborate and highly complex task that future automated can expire by the start of the self organizing networks according to Telefónica. New, additional sites on the NET will be added in the course of the integration work, the self organizing network acquires the required configurations to connect with neighboring mobile radio station. Here, the individual parameters are defined so that local customers always is the best network available.

the ability of self organizing networks, which is supposed to be able to adjust relative to neighboring nodes or neighbouring radio cells, immediately contribute to a more stable supply. A base station fails, for example, at a site, the coverage gap populate the best back through the automatic configuration of neighbor nodes. For the stations in the immediate vicinity are redefined, so the company. On the other hand, capacity at a particularly high needs – can be increased flexible during town festivals -.

“due to the technical convergence around the world are no more complex network as it does exist two GSM, UMTS two – and two LTE networks the Telefónica Germany. One of the reasons why the self organizing network represents an integral part of the maintenance of our network. This innovative technology provides insight, how networks will work in the future”, says Georg major Boes, head of radio planning, who is responsible for the introduction of SON.

Telefónica Germany wants to pass in the future more and more measures on the self organizing network, to make the network even greater flexibility and responsiveness.
