Abstract:
Offering vertical services to subscribers and service providers is an avenue to immediately improve the competitiveness of digital subscriber line access service, for example of the type offered by a local exchange carrier. To deliver high-quality vertical services, however, the underlying ADSL Data Network (ADN) or the like needs to establish Quality of Service (QoS) as a core characteristic and offer an efficient mechanism for insertion of the vertical services. The inventive network architecture introduces QoS into the ADN, in a manner that enables the delivery of sophisticated and demanding IP-based services to subscribers, does not affect existing Internet tiers of service, and is cost-effective in terms of initial costs, build-out, and ongoing operations. The architecture utilizes a switch capable of examining and selectively forwarding packets or frames based on higher layer information in the protocol stack, that is to say on information that is encapsulated in the layer-2 information utilized to define normal connectivity through the network. The switch enables segregation of upstream traffic by type and downstream aggregation of Internet traffic together with traffic from a local services domain for vertical services and other local services. Systems coupled to the local services domain alone or in combination with software in servers and/or a user's computer enable a testing of connectivity, throughput, QoS metrics and the like through selected points of the ADN network.
Abstract:
A network architecture includes a switch that can examine and selectively forward packets or frames based on information encapsulated in layer-2 information in the protocol stack. The switch segregates upstream traffic by data type and aggregates downstream Internet traffic with traffic from a local vertical services domain. The network architecture provides an efficiency way to insert vertical services.
Abstract:
A localized wireless gateway system provides wireless telephone communication and provides access to a public packet data network, such as the Internet, for at least voice telephone type communications. The wireless gateway system includes a number of base stations, essentially built around computers with digital transceiver circuitry, which provide an air interface to a number of digital terminal devices. The terminal devices communicate audio information in a standard digitized and compressed data format. The base stations provide two-way communications of the audio data over a public packet switched data network, either directly or via a local area network and a server coupled to the public data network. A server and local area network provide local voice and data communications as well as voice and data communication access to the public packet data network.
Abstract:
An enhanced name translation server, for use on a packet data network such as the Internet, executes a conditional analysis in response to at least some queries or requests for name translations. For example, the server may return a different destination address at different times or in response to translation requests from different terminals. The server also can query a primary destination terminal device, and condition the response to the calling terminal on the status of the primary terminal. For example, if the primary terminal is ‘live’ the server forwards the address of that terminal to the calling terminal device to set up communications. Otherwise, the server returns alternate destination address information. The server also supports a wide variety of different types of translations, including domain name to address, domain name to telephone number, and telephone number to address. The enhanced translations offer called customers numerous options for controlling communications directed toward them, and the customers may elect to apply these options both to their data communications services and their voice communications services through the packet data network.
Abstract:
An Internet telecommunication system in accord with the invention combines the capabilities of the Advanced Intelligent Network (AIN) with those of the internetwork commonly known as the Internet. Functions associated with the Internet Domain Name Server system are enhanced using AIN data and processing. Voice grade telephone calls from a fixed position Internet PC to a roaming wireless personal communication system are enabled. Home Location Register data from the control point of the AIN is forwarded into the Internet Domain Name Server for conditioning the IP lookup and addressing to determine the ultimate call routing. Internet calls may also be automatically completed by the system to addresses other than the ones entered by the caller.
Abstract:
An internetwork (such as the Internet) telephony system and method incorporating architecture and methodology which facilitates a high degree of scalability. The scalability provides improvement dealing with usage recording, usage pricing, billing account management, and fraud control. The scalability is achieved primarily by bundling of usage recording, pricing, authorization and billing practices in one logical database object which may be physically distributed. A predefined set of network elements are provided access to the database object to obtain authorization for a call along with limitations on the maximum cost or duration of the call for the particular account involved. The database object records usage statistics relating to the completed call, including pricing, and this data is available for virtually immediate billing. The database object provides to customers on a virtual real time basis the customer's usage statistics, including statistics for a call in progress. The operation proceeds in the following manner. Each Internet telephone service subscriber will have at least one billing and authorization account maintained in a database on the Internet. During set-up of a call, the hop-off gateway will obtain identification and password information from the caller. The gateway then communicates with the database to determine if the call is authorized and to negotiate the overall billing algorithm. When the call if finished, the gateway will report usage data to the database for billing purposes.
Abstract:
An advanced intelligent network (AIN) comprises an services control point providing fully integrated service logic for both narrowband and broadband communications. When a terminating trigger event of a switch on the phone number of the line serving a customer detects an incoming telephone call, the switch sends a query to the services control point with the calling number of the incoming call. The services control point retrieves calling party information corresponding to the calling number directly from a line identification database and issues a send data transaction with the retrieved calling party information to the customer's set-top box. The calling party information is then displayed on the customer's video display.
Abstract:
A communications network system having an advanced intelligent network (AIN) controlling the system provides narrowband and broadband communications to customer premises. The system includes a narrowband network for narrowband communications including at least one signal switching office and a signal system. The signal switching office routes narrowband calls and detects an outgoing narrowband call from a customer at a customer premises and also detects dialed digits corresponding to such outgoing narrowband call. A broadband network for broadband communications is connected to video equipment at the customer premises. The video equipment includes a video display and is connected to the broadband network via an addressable settop box. A services control point in the advanced intelligent network is operative to perform network service logic programs for routing narrowband communications in the narrowband network. At least one of the network service logic programs is responsive to a query from the at least one signal switching office resulting from detecting the outgoing narrowband call and also detecting the dialed digits corresponding to that call. The service logic program instructs the services control point to initiate a data transaction to send data to the broadband network. The data includes the dialed digits. The dialed digits are displayed on the video equipment and request a response from the customer. The customer responds and instructs the narrowband switch as to whether or not to complete the outgoing call.
Abstract:
Supporting virtual private networks by using a new layer 3 address to encapsulate a network-bound packet so that its context information, from which a layer 2 (e.g., MAC) address can be derived, is preserved. If this encapsulation was not done, the layer 2 address would change over each segment of the network. Thus, the encapsulation preserves the concept of group identification, using at least a part of the context, over the entire network and not just at the edge of the network. If a packet is received from the network (to be forwarded to a customer), the layer 3 address that was added in the encapsulation is stripped off. The original layer 3 destination address may be used with a client device addressing table to determine a new context information, and a layer 2 (e.g., MAC) address of a destination client device.
Abstract:
The quality of service existing in a data packet network during the course of communication of a voice call through a data network, such as the Internet, is monitored. A minimum acceptable level of service may be predefined with a threshold quality level stored in the user's Call Processing Record (CPR) in the AIN Integrated Services Control Point (ISCP). If the monitored quality is maintained in excess of the stored threshold, communication of the call continues through the established course of transmission. If the measured quality of service on the data network is not satisfactory, the routing of the call is changed to communication solely through a voice telephone network connection, which may include an Interexchange Carrier link, without terminating the call. The packet data network is thereby bypassed to obtain voice grade quality while maintaining the call.
