A method and system is used in a communication network for charging a flat- rate for a customer's Nominal Bit Rate (NBRp) of the network as well as providing a variable actual Nominal Bit Rate (NBRr) suitable for momentarily desired high nominal bit rates requested by the customer. In one embodiment, the network provides a maximum pool size (Smax) which is predefined between a network operator and the customer. In another embodiment, instead of having the maximum pool size, the network provides the variable NBRr by filling the NBR pool progressively as a function of NBRp, a customer's desired Nominal Bit Rate (NBRd), and a constant z, for a period of time. A momentarily much higher NBRr can be provided based on the capacity of the filled NBR pool. |
