`
`A method performed by a web

`including one or more web
`servers coupled to a tandem
`access controller serving as an
`intelligent interconnection
`between at least one packet
`network and a second network

`“Rather, it redirects calls to subscribers. The
`TAC 10 provides intelligent interconnection
`between a calling party and a subscriber. The
`reader should keep in mind that although only
`one tandem switch 16 is shown in FIG. 1, the
`invention will apply equally well to a network of
`tandem switches, as shown in FIG. 2. FIG. 2 also
`illustrates how the subscriber can make calls
`using voice over IP via a conventional digital
`telephone 21.
`
`[0037] FIG. l illustrates the preferred method for
`an authorized subscriber to modify the 3rd-party
`control criteria by means of the world wide web
`22 (and web server 23) using an internet

`“The present disclosure will describe an
`invention which, in one embodiment, provides
`a distributed system for interconnecting one or
`more Network Access Servers, which are
`coupled to a data network such as the Internet,
`to a circuit switched Time Division
`Multiplexing telephone network that uses
`Signaling System 7 protocols for signaling.
`The interconnection is achieved, in part, using
`a protocol converter that is configured as a
`Signaling Access Server ("SAS") and that
`interworks with a Network Access Server
`("NAS"). "Interworks" means, for example,
`that the Signaling Access Server commands
`and manages the Network Access Servers
`using a signaling and control network; it is
`also possible for the NAS to place outgoing
`calls through the SAS to an SS7 network. 4:5-

`first call (from the calling party 20 to the

`public phone number) to the TAC 10, which in
`turn places a second call, subject to 3rd-party

`call. The TAC 10 is connected within the
`subscriber's local service area so calls from TAC
`10 to the subscriber do not incur a toll.

`When the subscriber 12 terminates (or answers)
`the second call, the TAC 10 terminates the first
`call and connects it to the second call, thereby
`connecting the calling party 20 to the subscriber

`TAC 10, using the subscriber's public phone

`private phone number and connects the two

`receiving, at the tandem access
`controller, a first call request and
`call data which is associated with
`a first call originated by the
`calling party via either the packet
`network or the second network,
`
`
`
`natively using Internet Protocol, or the calls
`may be coupled to another gateway and rejoin
`the public switched telephone network ("hop

`Network Access Server and SAS provide

`
`“FIG. l shows a tandem access controller (TAC)
`10 that allows an authorized subscriber 12 to
`establish 3rd-party control criteria for calls to the
`subscriber's telephone 14 (having a "public"
`phone number that callers dial). In one
`embodiment, the TAC 10 is a programmed
`processor. The TAC 10 may use any
`combination of hardware, firmware, or software
`and, in one embodiment, is a conventional
`computer programmed to carry out the functions
`described herein.”
`
`[0033] The TAC 10 is connected to or inside the
`conventional PSTN tandem switch 16 such that
`calls may flow through the TAC 10 in the same
`manner as the existing PSTN tandem switch,
`except that additional 3rd party features are
`applied to the call. As is well known, PSTN
`tandem switches are exchanges that direct
`telephone calls (or other traffic) to central
`offices 17, 18 or to other tandem switches.
`Details of the operation of the existing phone
`
`[T]he software components comprise
`instructions which, when executed by the first
`server, cause the first server to carry out the
`steps of receiving a call setup message from
`the telephone network that contains a master
`telephone number; sending a responsive
`message to the telephone network that
`contains a specific telephone number
`associated with one of the second servers; and
`setting up a call between the telephone
`network and one of the second servers that is
`associated with the specific telephone number.
`A related feature is that the software
`components further comprise instructions
`which, when executed by the first server,
`cause the first server to carry out the steps of
`receiving a call offer message from the
`telephone network that contains the specific
`telephone number.” 3:18-31
`
`“On the other hand, the originating protocol
`adapter 1412 may not be able to find the
`corresponding call instance 1420, for example,
`because the message is the first message

`Telecommunications, copyright 1999,
`incorporated herein by reference. Additional
`details may be found in the numerous books
`describing the PSTN.
`
`[0034] The PSTN tandem switch 16 directs a
`first call (from the calling party 20 to the
`subscriber's phone 14 using the subscriber's
`public phone number) to the TAC 10, which in
`turn places a second call, subject to 3rd-party
`control information, to the subscriber's "private"
`phone number without yet terminating the first
`call. The TAC 10 is connected within the
`subscriber's local service area so calls from TAC
`10 to the subscriber do not incur a toll. When the
`subscriber 12 terminates (or answers) the second
`call, the TAC 10 terminates the first call and
`connects it to the second call, thereby connecting
`the calling party 20 to the subscriber 12. Hence,
`the calling party essentially calls the TAC 10,
`using the subscriber's public phone number, and
`the TAC 10, after processing the call using the
`selected features, calls the subscriber, as
`appropriate, using the subscriber's private phone
`number and connects the two calls.”
`
`“Certain advantages that can be obtained using
`the invention include the following:
`
`Web-Based Telecom Navigator Manage
`Incoming Call Control
`
`pertaining to a call.” 13:27-31
`
`“Signaling Access Server 112 can produce call
`detail records that are similar to those
`produced by switches or other network
`elements, because Signaling Access Server
`112 has complete access to all signaling
`messages passing through it.” 19:6-10
`
`“FIG. 7A specifically shows messages
`communicated for normal setup of a call,
`originated by the public switched telephone
`network as represented by SS7 trunks 20,
`without alerting, and without continuity
`testing. Initially the Signaling Access Server
`112 is in the Idle state 702. The network 20
`delivers an Initial Address Message 704 to the
`Signaling Access Server 112. Signaling
`Access Server 112 sends a Setup message 706
`to one of its associated Network Access
`Servers 118. The Network Access Server 118
`responds with a Call Processing message 708.
`Signaling Access Server 112 interprets the
`Call Processing message as an affirmative
`acknowledgment and, accordingly, Signaling
`Access Server 112 sends an acknowledgment
`message 710 to network 20.
`
`Network Access Server 118 then establishes a
`call connection. For example, in the ISP dial-
`up context, Network Access Server 118 may
`select a modem or other connecting device at
`the premises of an Internet Service Provider.
`When the connection has been established,

`
`“[0041] FIG. 4 is a flowchart of actions that may
`be taken by the TAC 10 in response to the
`subscriber (or other service) controlling the
`TAC, using the web or other packet-based
`system, to change the subscriber's telephone
`provisioning or perform another function, such
`as make a VoIP call.”
`
`Network Access Server 118 sends a Connect
`message 712 to Signaling Access Server 112.
`The Signaling Access Server 112 responds by
`sending an Answer message 714 to network
`20. Conventionally, the Answer message
`indicates that a called party has answered a
`telephone or other network element, however,
`in this context the Answer message indicates
`that call setup is successful and a connection
`has been established. Signaling Access Server
`112 then enters a Conversation state 716 in
`which a voice conversation or data
`conversation occurs.” 38:12-40.
`
`“The system 2 may also implement a voice-
`over-Internet Protocol application, by which a
`Network Access Server may accept voice
`calls, fax calls, and dial termination calls, and
`carry such calls over the Internet. The calls
`may terminate either at a device that operates
`natively using Internet Protocol, or the calls
`may
