Abstract
Abstract A method and system are provided for calculating the total service capacity for multimedia traffic under aggregate traffic conditions within a shared transmission medium, such as an ATM network. A total number of different types of telecommunication traffic is specified by the network operator or network designer. Each different type of network telecommunication traffic is referred to as a service. Next, each week is partitioned into several busy periods. This partitioning is provided by the network operator and may include multiple days, for example: Monday-Friday; and, Saturday-Sunday. Thereafter, for each busy day described above, the day is further partitioned into several busy periods, each period discernible from a previous period by the level of activity expected within the network at that time. For example, 8:00 a.m.-5:00 p.m.; and, 5:00 p.m.-7:00 a.m. Once again, this information is provided by the network operator or network designer. Thereafter, for each busy period identified and for each service a specification of the length of that period, a probability that a user will access the service during that busy period, a percentage of all subscribers who subscribe to and use that particular service and the average session duration are specified. These values may be obtained from measurements, research literature or from standards bodies. The simultaneous capacity for each busy period for each service is then calculated. These inputs may then be utilized to calculate the total service capacity for the network. That is, the maximum number of users which can subscribe to each service within the network.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
162 words
A method for determining total service capacity for a plurality of heterogenous telecommunication services under aggregate traffic conditions within a network having a shared transmission medium, said method comprising the steps of: specifying a total number of heterogenous telecommunication services within said network; partitioning each week into a plurality of busy periods; determining a maximum simultaneous capacity for each of said plurality of heterogenous telecommunication services during each of said plurality of busy periods, based upon a required quality of service for each of said plurality of heterogenous telecommunication services; determining a probability of user access of each of said plurality of heterogenous telecommunication services during each of said plurality of busy periods; and determining a total service capacity for each of said plurality of heterogenous telecommunication services within said network based upon said determined maximum simultaneous capacity and said determined probability of user access of each of said plurality of heterogenous telecommunication services during each of said plurality of busy periods.
Claim 2
Independent Claim
162 words
A method for determining total service capacity for a plurality of heterogenous telecommunication services under aggregate traffic conditions within a network having a shared transmission medium, said method comprising the steps of: specifying a total number of heterogenous telecommunication services within said network; partitioning each week into a plurality of busy periods; determining a maximum simultaneous capacity for each of said plurality of heterogenous telecommunication services during each of said plurality of busy periods, based upon a required quality of service for each of said plurality of heterogenous telecommunication services; determining a probability of user access of each of said plurality of heterogenous telecommunication services during each of said plurality of busy periods; and determining a total service capacity for each of said plurality of heterogenous telecommunication services within said network based upon said determined maximum simultaneous capacity and said determined probability of user access of each of said plurality of heterogenous telecommunication services during each of said plurality of busy periods.
Claim 3
Dependent Claim
39 words
