Abstract

A network access optimization modeling initiative (NAOMI) that enables the operating personnel of a wide area service provider to configure the trunk connections of a telecommunications access network so as to gain access to the end offices of local area access providers at a given level of performance at minimal cost. Upon request, NAOMI optimizes the direct end office trunk and tandem trunk connections between the serving wire center (SWC) to which a wide area service provider gains access to a local area access provider and the end offices to which long distance calls are directed. In operation, NAOMI first obtains a configuration of the access network so that the respective positions of the points-of-presence (POPs) of the wide area service provider, tandem switches, end offices and various direct end office trunks (DEOTs) and tandem trunks of the access network are known. NAOMI then defines a tandem service area (TSA) to contain at least the POP and the end office through which calls from the wide area service provider are routed. Once the TSA is defined, an optimization process takes place in which the locations of the POP and the end office, the end office's traffic profile and servicing capabilities, the service provider's rates, and the tandem switches are taken into consideration. An optimized trunk configuration is generated at a given grade of service for a minimum cost in response to the optimization process. The optimal trunk configuration is then presented to the operating personnel of the wide area service provider who can follow the recommendations and request the local area access provider to change its trunk configurations for connecting the wide area service provider's POP to its end office.
