  • Patent number: 7346043
    Abstract: Methods are described which enable the operator of a network such as an Internet protocol (IP) network to allocate ingress and egress channel capacity for the use by different services or for use by different service providers. The methods can prevent a service provider or a service from overusing network capacity. The methods also enable the network operator to temporarily allocate unused capacity if demand for a service exceeds previously allocated capacity. Further a method is described whereby capacity on a Voice over Internet protocol (VoIP) network is sold to service providers with guarantees for the number of available channels, where the channel capacity guarantees could be global, or by any type of subdivision. In addition to having a committed channel capacity, the service provider could be allowed to exceed the committed capacity whenever excess capacity is available on the network.

  • Patent number: 5392344
    Abstract: The routing of calls of different classes of services as well as the administration thereof is enhanced by associating each such class of service with a number of parameters common to such services, such that each class of service, as well as a new class of service, may be readily identified by its respective parameter values. Accordingly, the routing and administration of calls of different classes of services may be handled in a systematic, straight forward manner so that basic network capabilities may be made available to various services using an administratively defined menu like structure. In addition, such class of service advantageously partitions network bandwidth allocation, call routing priority, voice/data transport, and traffic data registers into respective classes of services.

  • Patent number: 5226075
    Abstract: A communication network uses a network switch number (NSN) and a class-of-service classification (COS) code to route calls through the network. When a call is received at an originating switch of the network, the dialed number is used to select the NSN which identifies a network terminating switch which connects to the called party. The network uses received call signaling information and stored trunk information and possibly network database information to determine the COS code. The COS code is also used at the terminating switch to identify the type of service trunk to connect to the called party. In another feature, only the network switch number is used to route the call over the network. In accordance with yet another feature, the COS code may be used to select specific network trunks without requiring the specification of the NSN.

  • Patent number: 5185785
    Abstract: A transaction recording and rating method and apparatus rates communication transactions completed using one or more Carrier Switched Network Point Of Attachment (CSN POA) locations of a communication network. The network stores a unique code for each CSN POA location. The rating systems store rating parameters associated with each CSN POA code. During a transaction (e.g., a call), one or more CSN POA locations are identified and their CSN POA codes are recorded. A transaction charge is calculated from the prestored rating parameter(s) obtained using the one or more CSN POA codes in addition to other information.
