Inconsistency and errors in radio access network parameters often result in loss of revenue for the operator. The actual reason of the lost revenue loss may be dropped calls, lower service quality and/or other unnecessary variations in performance across the network. 

The task to keep parameter settings in check is complex. There is nothing that cannot be done, but the effort may be significant. 

Cedar is designed to save valuable time for the radio network engineer. Furthermore Cedar allows users to investigate and verify the network parameters (and their changes) in a multi-vendor, multi-standard context. 

Selected features

• View, study and analyze multi-OMC, multi-vendor (Ericsson, Nokia, Siemens, and Alcatel) and multi-standard (2G, 3G) data.

• Meta-data driven access model supporting TEXT files, command files (MML) and standardised XML formats.
  
• No need to deploy a new data repository - i.e. no vendor lock-in or additional CM databases.
• Comprehensive built-in functions to facilitate data verification and detection of common parameter problems, such as non-mutual 3G-2G handover neighbors and much more
• Define automatic and explicit cell rules in order to classify cells.
• Define global and/or class-dependent data verification rules.
• Feature-rich rules engine supporting complex user-defined parameter rules.
• Compare historic, active and planned configurations.
• Detect differences between actual network data and defined entreprise-wide soft or hard constraints.
• Export selected data fields, function results and/or rule results.
• includes E-Learning. Multimedia walkthrough of selected use cases. Audio for any language can be added at request.

Supported formats

The Cedar architecture allows for adding support for other formats with a limited effort.

Cedar has a meta-data driven parser. This means that minor format changes (such as new, renamed, missing or deleted parameters) typically won't require updates of neither Cedar or the associated configuration files.

Cedar Server

Cedar Server acts as a communication node - automatically performing data preprocessing on dumps from the OSS served. Cedar Server may be deployed on any platform supported by the Glassfish application server and Postgres. Cedar Server is entirely managed and used via a web interface.

Deployment

Cedar is easily installed on a stand-alone laptop or workstation. The installation package includes the required Java™ runtime environment. No additional software or configuration is needed. Cedar is tested on Windows 2000, Windows XP, Windows Vista and Linux, but may also de deployed on other platforms.

Cedar client running on Vista

The basic components of Cedar Server are a Java™ Application Server and a Postgres relational database. The typical configuration is a 64-bit operating system with a minumum of 8GB of RAM. Cedar Server is tested on Windows Server 2003 and Windows Server 2008, but may also be deployed on a range of other platforms.

Characteristics

The development of Cedar has been an ongoing effort since 2002. The functionality has gradually grown richer and richer over the years, but we have always kept our focus on one key aspect: Make it as fast as possible.

There are occasions when Cedar need to perform considerable data processing, but most users familiar with other applications operating on the same type of data will be surprised to experience the performance provided.
