T-Mobile is a business unit of Deutsche Telecom. Responsible for mobile operations, it concentrates on the most dynamic markets in Europe and the United States. By the end of the first quarter of 2009, more than 149 million customers were served on ten T-Mobile markets. T-Mobile is gradually integrating OSS systems used in its European operations in order to simplify network management and provide a common management platform for an entity that is composed of multiple national GSM operators in Europe.

Implemented products

T-Mobile Austria decided to face the challenge together with Comarch and build a central resource inventory based on Comarch OSS Suite modules. The proposed solution, covering different technologies, vendors and layers, consisted of:

During the implementation of the project, additional challenges arose that had to be solved, including:

  • Design of mechanisms supporting inter-domain connectivity, including algorithms for matching data coming from different vendor and technology domains
  • Customization of mechanisms supporting the planning department.

The results

The successful Comarch implementation fulfilled T-Mobile Austria’s requirements including:

  • Central repository maintaining data ranging from physical resources like cables, wires and switches, IP devices, 2G and 3G network elements to logical resources like Ethernet, microwave links, leased lines, IP connections, IP addressing, 2G and 3G mobile hierarchy
  • Up-to-date information is assured by nightly reconciliation with a live network, carried out by the Comarch OSS Mediation platform
  • Easy import and export of data assured by in-built mechanisms of the Comarch Framework
  • Visualization of data using a broad set of views fulfilling the requirements of different groups of users
  • Predefined library of equipment models and templates, allowing quick creation of a new device with its internal structure
  • A number of validation mechanisms verifying the compatibility between equipment e.g. insertion of a card to an incompatible slot is not allowed
  • Support for different groups of planners realized by the mechanism of network snapshots


Benefits for T-Mobile

  • Reduced maintenance costs by replacing many scattered systems using the comprehensive resource inventory
  • Higher resource utilization due to comprehensive and up-to-date resource view and planning capabilities
  • Comarch Resource Inventory is an enabler for improved Incident and Problem, as well as Change Management processe
