  • Patent number: 6522741
    Abstract: According to the invention, a method and apparatus are disclosed for hybrid network call delivery routing using a serving switching element point code and temporary destination location number. Using a hybrid system as taught by the present invention, existing communications network can be migrated to advantageously use point code call routing. Moreover, the disclosed hybrid methodology does not require end-to-end use of point code routing. Rather, a provider's network can transition the heavily trafficked network elements to reduce overhead and costs, while less heavily used network elements can continue to use destination phone number routing or be changed to support point code routing when the cost of its migration is justified.
