Telefónica O2 Germany GmbH & Co. OHG belongs to Telefónica Europe and is part of the Spanish telecommunication group Telefónica S.A. The Company offers its German private and business customers postpaid and prepaid mobile telecom products as well as innovative mobile data services based on the GPRS and UMTS technologies. In addition, the integrated communications provider also offers DSL fixed network telephony and high-speed internet. Telefónica Europe has nearly 49 million mobile and fixed network customers in Great Britain, Ireland, the Czech Republic, Slovakia and Germany.
For this project, O2 in Germany did not restrict itself to acquiring a solution that would act as a manager of managers, integrating with its already-existing management systems. Instead, the company aimed to completely replace the element management systems in use. This required a system with a direct interface to thousands of network elements from different vendors. In order to achieve this, a set of specific data adapters needed to be created.
One challenge was to equip the system with functionalities enabling the configuration of every network element. The solution should allow the operator to perform all the actions available through the dedicated Element Management Systems used previously, including firmware upgrades, while at the same time should enhancing these systems with additional features. Further, the integration of the systems entailed the development of unified network-level management functions. Apart from that, the system needed to correlate and subsequently present data gathered from all the managed network elements in one consistent view.
With the implementation of Comarch OSS Suite, an advanced network and service management solution, O2 in Germany aimed at unifying and simplifying the whole network management process while at the same time decreasing maintenance costs. Taking a closer look at the telecommunications network of any existing operator, it is noticeable that it comprises a wide range of network elements supplied by various vendors. The reason for this is quite simple: the highly-competitive nature of the equipment market allows operators to choose the most costeffective and technologically-advanced solution paying little attention to by which vendor it is provided.
Going one step further, it is important to remember that operators need to manage all of these network devices. Of course, this can be done with a set of disparate proprietary management systems; however, this kind of approach is usually expensive and has several flaws unacceptable for O2. What the operators should be trying to achieve is a single, comprehensive and integrated Network Management System that directly manages and monitors all the different network elements and services.
The implementation of the Comarch OSS Suite was followed by a set of benefits including:
Thanks to the wide scope of its functionalities, the Comarch OSS Suite is a sure step towards an integrated network management system, simplifying the management process and reducing OPEX.
