ABSTRACT:
TECHNICAL FIELD OF THE INVENTION
The present invention relates in general to telecommunications signal processing and more particularly to a method of routing telecommunications signals in a telecommunications network.
BACKGROUND OF THE INVENTION
Telecommunications switches are used to route telecommunication traffic through a telecommunication network. The telecommunication switches use routing tables to determine where the telecommunication traffic is to be transferred. Many of these routing tables are static in nature and extremely difficult to update and change. Even those routing tables which might be dynamically updated only provide routing information for the telecommunication switch with which it is associated. However, routing determinations may be performed by any of a number of processors within the telecommunications switch. Therefore, it is desirable to dynamically provide routing information to each of a plurality of processors within a telecommunications switch.
SUMMARY OF THE INVENTION
From the foregoing, it may be appreciated that a need has arisen for a telecommunication switch that can provide routing of telecommunications signals as dynamically controlled by a network processor. In accordance with the present invention, a method of routing telecommunication signals in a telecommunications network is provided that substantially eliminates or reduces disadvantages and problems of fixed routing techniques in conventional telecommunications switches.
According to an embodiment of the present invention, there is provided a method of routing telecommunication signals in a telecommunications network that includes receiving a plurality of dynamic routing recommendations. A determination is made that telecommunications signals are to be transferred from a first switching element to a second switching element, possibly through one or more intermediate switching elements. One of the plurality of dynamic routing recommendations are identified to perform the transfer. The telecommunications signals are then transferred from the first switching element to the second switching element in response to the identified dynamic routing recommendation.
The present invention provides various technical advantages over conventional fixed routing techniques. For example, one technical advantage is due collect congestion data from processors within a telecommunications switch and generate routing recommendations based on the congestion state of the telecommunications switch. Another technical advantage is to provide routing recommendations to a telecommunications switch that can be dynamically changed in response to the congestion state of the telecommunications network. Other technical advantages may be readily apparent to those skilled in the art from the following figures, description, and claims.
