Abstract

Monitoring the health and status of a space based communication system is required to diagnose problems, analyze trends, and predict future perfor- mance. Performance of this function requires col- lecting health and status data from network elements in the communication system. There is a trade-off involved in performing the required data collection. Detailed data collection on all aspects of the hard- ware and software operation is desirable in order to fully evaluate the health and status of the system. The disadvantage is that the data collection uses sys- tem bandwidth that would otherwise be revenue producing. The goal is to get as much useful infor- mation as possible while using as little revenue bearing bandwidth as possible. This invention pro- vides a means to collect a small amount of critical data, analyze this data in real time, and take action based on this analysis. This action may be to collect more detailed data related to a call.

SYSTEM FOR REAL TIME AND ADAPTIVE MONITORING OF THE HEALTH AND STATUS OF A TELECOMMUNICATION SYSTEM

by Joseph Lester, Scott Blanchard and Dean Vanden Heuvel

ABSTRACT

  Monitoring the health and status of a space based communication system is required to diagnose problems, analyze trends, and predict future perfor- mance. Performance of this function requires col- lecting health and status data from network elements in the communication system. There is a trade-off involved in performing the required data collection. Detailed data collection on all aspects of the hard- ware and software operation is desirable in order to fully evaluate the health and status of the system. The disadvantage is that the data collection uses sys- tem bandwidth that would otherwise be revenue producing. The goal is to get as much useful infor- mation as possible while using as little revenue bearing bandwidth as possible. This invention pro- vides a means to collect a small amount of critical data, analyze this data in real time, and take action based on this analysis. This action may be to collect more detailed data related to a call.

PROBLEM STATEMENT

  One area of interest for health and status mom- toring is call related data. For example, call related data includes monitoring how many calls are made, who is making calls, who is being called, where the

call is originating from, what gateway is handling the call, etc. If this call related data is monitored in real time then problems can be identified and ana- lyzed while they occur. For example, if the system recognizes that a call is being made by a subscriber who has complained about the quality of his service, then it can immediately trigger a bit error rate (BER) measurement for the subscriber.

  For another example, the system may detect a problem occurring in one area of the network (e.g. a geographical location, or a particular space vehicle, or a particular gateway), and trigger additional col- lection for that particular problem.

  This kind of analysis is very difficult in current systems. In current systems each element, or node, of the communication system reports status informa- tion to a central database. To monitor an individual call, all elements involved in the call must report all call related data to the central database. The data- base must then be queried to correlate the data from all the elements to find all of the dam related to the call. This requires large amounts of data storage, and cannot be done in real time.

  What is needed is a system to filter out all but call related data, analyze this data in real time, and take action based on this analysis. This paper dis- cusses a method that addresses these needs.

THEORY OF OPERATION
