Abstract: AIN based methods and apparatus for transitioning telephone numbers and customers from the PSTN to a VOIP network are described. AIN line number portability features are used to allow a few gateway switches that interconnect the PSTN and VOIP networks to service customers whose telephone numbers were originally serviced by several remote PSTN switches. AIN LNP triggers are used to forward PSTN calls, directed to the PSTN switch previously used to service a telephone number, to the gateway switch assigned to route such calls to the IP network. AIN triggers set at the gateway switch insure that the subscriber with the ported telephone number continues to receive AIN services provided before the telephone number was ported to the IP network. Calls from ported telephone numbers to telephones in the PSTN are billed from PSTN switches through the use of AIN functionality and triggers set at the gateway switch.

Abstract: AIN based methods and apparatus for authenticating and authorizing people to register information corresponding to a telephone number, e.g., in an ENUM database, are described. The methods of the invention may be used to authenticate a party seeking to register telephone number related information with ENUM. A trigger is set on an ENUM registration line. Calls to the ENUM registration line activate the trigger causing LIDB information corresponding to the calling party number to be retrieved. The retrieved information, e.g., name, address and/or phone number is supplied to an ENUM registration service which returns a password to be used when updating or supplying ENUM registration information corresponding to the phone number from which the registration call is placed at some future time, e.g., via the Internet. Assigned ENUM passwords can be obtained when forgotten by placing a call to the registration service from the registered or associated phone number.

Abstract: In a public switched telephone network, interoffice call attempts to or from a line under surveillance generate a variety of query, response and release messages between the offices, as part of the normal procedures for setting up and tearing down the calls to and from the line. To insure that all calls under surveillance generate signaling messages, terminating, dialing and release triggers are set with respect to the target's line. As a result, the end office serving that line sends queries to a database on the signing network, receives response messages, and sends release report messages. A site processor compiles data from the signaling messages and forms a call detail record (CDR) for each call attempt relating to the target under surveillance. A central file server further processes the CDRs and supplies composite data regarding the target's calls through a data network connection to one or more law enforcement agencies.

Abstract: A lawfully authorized electronic surveillance operation requires reporting of detailed call data for a variety of calls associated with the subject of the surveillance. For at least some specified calls to or from the subject, the invention provides profile data in a switching office serving the subject that causes the office to generate accounting messages for each call, essentially in the same manner as for billing, regardless of whether the calls are billable. Accounting records formed from the messages are uploaded to a server system, for processing and formatting as necessary for delivery to the law enforcement agency. The surveillance could entirely rely on these accounting records for the data reporting. In the preferred embodiments, however, the surveillance also involves monitoring of common channel signaling messages to accumulate call detail records for surveillance purposes, with respect to many calls associated with the subject.

Abstract: Following the Communications Assistance for Law Enforcement Act (CALEA), the FBI developed a standard set of communication services and interfaces. for lawfully authorized electronic surveillance, for both call data recording and content recording. Existing public switched telephone networks use a variety of switches. Not all of the switches in use are capable of performing the routines required by the CALEA standards. In accord with the invention, Advanced Intelligent Network (AIN) and/or Local Number Portability (LNP) functionality controls routing and billing of incoming and outgoing calls for the surveillance target. The routing is handled in such a manner that calls to and from the target are directed to a regional switching office which performs those functions for switches in the region which lack that capability. Through this arrangement call detail records (CDRs) regarding the target are accumulated and transferred to a law enforcement authority.

Abstract: Advanced Intelligent Network (AIN) platforms include data bases populated with information pertaining to all phone numbers within a communications network. A large number of telephone numbers may concurrently be prespecified in a data base by a subscriber, together with alternate telephone number destinations corresponding to different locations, for redirection. Redirection set up for all of the subscriber's lines is accomplished by a single data entry operation into the data base in accordance with a template or table of designations customized by the subscriber. Redirection information may be transmitted to the AIN data base via a telecommunication line and an adjunct processing device associated with the AIN data base, using a terminal interface or dialed digit inputs; or the redirection information may be entered by interaction with a network switching office which sends the information to the data base via the network's signalling channels.

Abstract: Disclosed is a method of utilizing a public switched telecommunications network which includes a voice messaging system (VMS) to provide a reliable and flexible notification service to deliver to designated persons a message which may be prestored or created at the time of initiating the notification. The list of persons to be notified is pre-established and permits multiple telephone numbers to be used to locate a single person or an alternate person. Pagers may be simultaneously or sequentially called requesting that the desired person call in for their message. The list of persons to be notified may be changed by the system coordinator from any DTMF telephone and the telephone numbers or pager numbers assigned to persons to be notified may be changed by such persons from any DTMF telephone. Alternatively the list may be created or changed by the coordinator using a personal computer or ASCII data type device.
