Abstract
This paper introduces a novel traffic scheduling policy whose objectives is to maximize the profit of telecom telcos.Telecommunication network management is reconsidered from the business point of view, introducing competition between users forresources of the telecom telcos, in addition to existing competition between telcos themselves. Business control of network is supportedby loop back control that should be realized as on-line technology supplied with intelligent control algorithms. The results odsimulation, obtained through extensive testing, prove the correctness of proposed method for optimizing telco profit and show that,neither pure E nor pure L policy, can give the maximum profit. To specify and implement the proposed system we use unified modelinglanguage (UML).

Highlights
We propose a new concept aimed to maximize the profit earned by the telco, using the aforementioned brief periods of need to send or receive a specified content at the required quality of service (QoS)
The policy in the non-preemptive part is different. Since preemption in this part is not possible, each new contract is granted if the price offered is higher than the average of the previous ones by a certain amount, and, at the same time, higher than the minimum price contracted in the preemptive part
E policy is based on fixed bandwidth sharing among different classes of services (CoS)
Summary
Due to the fast technological advancements, telecom telcos face a number of challenges: The set of services offered to users rapidly becomes out of date and must be innovated continuously and updated frequently (almost on a monthly basis) [1]; Prices of IP equipment and optical connections rapidly decline, while the bandwidth increases; The presence of competition forces telcos to use the “cost-plus” pricing method, limiting the profit to a percentage (margin) of income, that is long term limited by the economy average; Telecom telco (telco) monopoly is not supported by government authorities any more, meaning that temporary monopoly can be based only on their know-how or technology; Traditionally, telecom business was a highly profitable industry, due to the high value of electronic communications for users, but it is expected that it will become an average or even low profit industry, as new and new competitors enter the market; Social and economic benefits from high quality and affordable communication services are proven practice in the societies of today, so that it cannot be expected that governments will allow monopolies in the future. Despite the current global economic crisis, telcos reported continued growth in the field of investment and in the field of income. This growth was still significantly reduced compared to previous years, so that telcos and equipment manufacturers seek new ways to maintain and improve the business.
