Optimi

In order to survive in an increasingly competitive environment, today’s cellular operators must focus on improving operational efficiency and minimizing capital expenditure, while at the same time delivering the highest quality end user experience. The optimal configuration for radio resource management (RRM) parameters is different for each sector in the network, and also varies with time. Therefore, in order to extract the most of the deployed network infrastructure, it is necessary to address the optimization of these parameters on a consistent, periodic and per-sector basis. Given the complexity of the task, the optimization is normally addressed manually and on a per-cluster or per-market basis, compromising the maximum performance that could ultimately be achieved by the network.

Optimi xParameters is a multi-vendor and multi-technology automated solution that dynamically optimizes key RRM parameters at sector level, thereby boosting system performance while minimizing CapEx and OpEx. It is designed to integrate into the operators’ existing system (utilizing the OSS or an analogous source of data) and fully automates the overall parameter optimization process, allowing a full closed-loop operation mode that comprises collection of data, optimization and parameter change implementation, which can be flexibly scheduled.

Use cases

• Exploit continuous adaptation of traffic management related parameters in order to improve quality indicators, handover success ratios and end user experience.
• Redistribute traffic dynamically in order to reduce the need for hardware upgrades in the network, while maintaining or improving quality.
• Boost the performance of a UMTS/HSPA network by optimizing key RRM parameters, including the ones controlling GSM-UMTS iRAT handovers.
• Shift traffic from GSM 850/900 to GSM 1900/1800 when carving the 850/900 GSM band to make room for a new UMTS or LTE carrier.
• Accelerate the integration process in rapidly changing networks (e.g. after a network consolidation process) by leveraging the capacity and quality handling capabilities of xParameters.

Benefits

• Enhanced network performance. Some examples from real networks (out of 40+ references worldwide):
  
  - Reduction of call drops in a GSM network ~10%.
  - Reduction of call drops in a UMTS network ~40%.
  - Reduction of handover failures ~25-45%.
  - Reduction of voice blocking ~50-75%.
  
  
• Significant CapEx reductions. Intelligent traffic management techniques improve the utilization of existing resources, delivering savings in radio resources of up to 0.16 saved TRXs per sector and band, and reductions of more than 50% in Iub congestion.
• Dramatic OpEx reduction through automation.
