Network operators are nowadays upgrading their access networks to cope with the increasing number of users and the increasing bandwidth required by services. However, cost plays a crucial factor. In order to decide which next generation access network will be implemented, an accurate cost evaluation should be performed. This evaluation requires a total cost of ownership model including a detailed model of the most costly operational processes: fault management and customer provisioning. These models help identifying the most costly sub-processes, where network providers should improve their cost efficiency. This paper presents detailed models for these operational processes and gives an approach to use them for estimating future operational costs.
