Minimization of drive tests in 3GPP release 11

Abstract: Minimization of drive tests is a feature introduced in 3GPP Release 10 that enables operators to utilize users' equipment to collect radio measurements and associated location information, in order to assess network performance while reducing the OPEX associated with traditional drive tests. However, in the increasingly complex wireless packet data networks of today, performance is affected by many different factors and cannot easily be estimated by simple radio measurements. Therefore, in 3GPP Release 11 specifications, MDT is enhanced in order to provide a more complete view of network performance. This article describes the MDT enhancements added in Release 11, explains how measurements collected by MDT can be used to draw conclusions that are relevant for network management, and discusses similarities and differences between MDT and traditional drive tests.

The Structure of Effective Governance of Disaster Response Networks: Insights From the Field:

Abstract: There is significant debate about the appropriate governance structure in a disaster response. Complex disasters exhibit both networked and hierarchical characteristics. One challenge in the field ...

SEC - a lightweight event correlation tool

Abstract: Event correlation has become one of the most important techniques in today's network management, and there is a clear trend to extend its use to other application domains as well. Unfortunately, existing event correlation systems are often platform-dependent and heavyweight solutions that have complicated design, being therefore difficult to deploy and maintain, and requiring extensive user training. Their complexity and size makes them often unfeasible to apply for smaller networks and for smaller event correlation tasks. Also, some systems are cumbersome to use outside the domain of network fault management. In addition, commercial event correlation products tend to be quite expensive. In this paper the author presents a lightweight, open-source, and platform independent tool for rule-based event correlation called SEC (simple event correlator), and describes its application experience.

Distributed service subsystem architecture for distributed network management

Abstract: A distributed service subsystem comprises one or more cabinets containing one or more computer systems, one or more administration consoles for controlling the computer systems in the cabinets, and a network interconnecting the administration consoles and the cabinets. Each of the cabinets includes a cabinet module interface controller (CMIC) coupled to and controlling one or more chassis management boards (CMBs). The CMBs are each adapted to communicate with one or more managed components in the cabinet through a component specific interface.

System and method for generating communication network performance alarms

Abstract: Statistical processing of event outcomes, such as call attempts or handoff attempts, allows reliable generation of performance alarms within a communication network without requiring analysis of historic performance data. Base station controllers might implement such statistical processing so that the controllers themselves rather than other, further removed network management entities generate performance alarms. Attendant advantages include but are not limited to relatively fast and reliable alarm generation using relatively small sample sets. These and other advantages permit detecting and reporting performance alarm conditions more quickly without sacrificing alarm generation reliability.
