Abstract
A method of allocating subscriber lines in a telecommunications network into speed bins. With the method, more intelligent business actions can then be taken in the provision of high-speed data services over the subscriber lines. For example, only qualified lines might be used for high-speed data services, with the other lines being allocated to POTS service. The lines are divided into speed bins using a pair of neural networks, with one predicting upstream speed and one predicting downstream speed. The combined predictions are then mapped to a speed bin, which is the basis for further business actions. The disclosure describes that the neural networks are created using conditional fuzzy logic to precondition the neural networks by line speed.
Claims17
A method of operating a telecommunications network of the type having a plurality of subscribers connected to a switch through a plurality of subscriber lines, the method comprising:
- a) making a plurality of one-ended electrical measurements on a subscriber line;
- b) preparing a feature vector from the electrical measurements;
- c) applying the feature vector to a first neural network to predict upstream data rate of the subscriber line if used to provide high speed data services;
- d) applying the feature vector to a second neural network to predict the downstream data rate of the subscriber line if used to provide high speed data services;
- e) combining the output of the first neural network and the second neural network to predict a service level of the subscriber line;
- f) taking a business action related to the delivery of high speed data services based on the service level for the subscriber line.
