Definitions

  • the present invention relates in general to a subscriber feature within a telecommunications network. More particularly, the present invention relates to a "do not disturb" subscriber feature to protect the privacy of a subscriber within such a network.
  • nuisance calls In telecommunications systems, so-called nuisance calls continue to be a problem. These nuisance calls may originate, for example, from a telemarketer, an incorrectly dialed number, a threatening or harassing caller, or a caller who merely calls at an inconvenient time. With developments in telephones and telecommunications systems, many approaches have been employed to reduce or eliminate calls from unwanted callers and/or calls at particular times.
  • the receiver may not be reconnected immediately after being placed on-hook, and thus the telephone is unavailable to the subscriber for a period of time after being placed on-hook. As a result, calls cannot be made during this time period, which is potentially disastrous in an emergency situation where the telephone is needed (e.g., police, fire, or medical emergency) .
  • placing the receiver off-hook serves to shut off the telephone receiver, thereby blocking all incoming calls.
  • some subscribers have resorted to commercially available telephone answering machines to provide call screening.
  • An answering machine is generally provided with a speaker, allowing the subscriber to hear the voice of the caller. The subscriber can then selectively pick up the receiver and talk to the caller once the caller has been identified.
  • This approach has several disadvantages. All calls including nuisance calls will ring the subscriber's phone, thereby interrupting the subscriber. Further, the subscriber must still go to the phone (or in this case, answering machine) and listen to the voice of the caller and determine whether to take the call, and thus manually screen the calls.
  • Telephone companies have begun to offer a calling line ID service that allows a subscriber to see the number of the caller, and perhaps his name. If the subscriber wishes to take the call, he picks up the phone; otherwise, the call goes unanswered and may be transferred to a messaging system after a number of rings. Unfortunately, such a service does not prevent the telephone from ringing, thereby disturbing the subscriber with a potential nuisance call.
  • call forwarding variable where all or selected incoming calls are directly forwarded to a predefined forward-to-number
  • call forwarding busy where all or selected incoming calls toward a busy called party subscriber are forwarded to a predefined forward-to number
  • anonymous call rejection where an incoming call connection to the subscriber is denied if the caller refuses to provide his calling line ID.
  • a service called Privacy Manager is currently provided by Ameritech Corp., of Chicago, Illinois and / or its subsidiaries. This service determines if the caller has a missing or blocked calling line ID. If so, the caller is prompted to either unblock the calling line ID or record his name. If the caller refuses, the caller is not connected with the subscriber
  • the present invention is directed to a "do not disturb" ("DND") telephone subscriber feature on a telephone system that prompts a caller for an access code, such as a personal identification number (“PIN”), and based on the caller's inputted response, determines whether to complete the call to a subscriber. If the caller enters a valid code, the call is placed to the subscriber's phone. Otherwise, the system hangs up, or alternately, sends the caller to a voice messaging system so that the caller can leave a voice message for the subscriber.
  • DND "do not disturb"
  • PIN personal identification number
  • the subscriber can activate / deactivate the DND feature by dialing a code on his telephone, such as *99.
  • the feature can be automatically activated / deactivated at pre-set times.
  • each caller can have a unique access code, or some or all the callers can share an access code.
  • FIG. 1 shows a simplified schematic diagram of a telecommunications network including local telephone sets and their associated central offices, a service control point, a voice messaging system, and a service package application in accordance with an embodiment of the present invention
  • Fig. 2 shows a flow chart of an exemplary method of operation of the system of Fig. 1 in accordance with the present invention.
  • the term "subscriber” is used to mean a subscriber to a telephone service and generally refers to the party being called, and the term “caller” is used to designate a party calling the subscriber.
  • the term "PIN” or "personal identification number” means a number which may be assigned to one or more callers. Thus, a PIN may or may not be personal .
  • DND subscriber feature in accordance with the present invention can be implemented as one of these subscriber features. By activating the DND subscriber feature, the associated subscriber is able to block or deny incoming call connections unless the caller provides a valid access code or PIN.

  • calling line number is used in its generally understood meaning to be the number which is dialed or input by a caller or source to reach a piece of terminating equipment on a calling line associated with the dialed calling line number.
  • a calling line number is commonly referred to as a telephone number or a directory number.
  • SSPs are interconnected by a plurality of trunk circuits. These are the voice path trunks that interconnect the SSPs to connect communications.
  • the term "communication” or "call” is used herein to include all messages that may be exchanged between caller and called party in the network illustrated in Fig.

  • the instructions may be to take some special action as a result of a customized calling service or enhanced feature.
  • the switch moves through its call states, collects the called digits, and generates further packets that are used to set up and route the calls.
  • Similar devices for routing calls among various local exchange carriers are provided by regional STP and regional SCP.

  • the caller 20 dials a number that is transmitted to its associated central office (the originating central office 30) in a conventional manner.
  • the central office 30 detects the caller's instructions and requests a call setup to the subscriber's central office (the terminating central office 70) via a service control point 50 in a conventional manner.
  • the terminating central office 70 determines if the DND subscriber feature in accordance with the present invention is activated for the subscriber 80. If the DND feature is not activated, the call is connected in a conventional manner. If the DND feature is activated, the caller 20 is prompted to enter an access code or a PIN, typically via a keypad at the caller's telephone. More particularly, it is contemplated that an AIN trigger is placed on the subscriber's line. When any caller 20 dials that number, the call is sent to an AIN service control point 50.
  • An application such as a service package application 35, that resides on the service control point 50 or separately, instructs the AIN end office (i.e., the originating central office 30) to prompt the caller with a message requesting the code (e.g., a prerecorded announcement or a synthesized voice, generated by a voice synthesizer, stating "The person you are calling is currently accepting only verified calls. Please enter the PIN code to continue.”).

If the caller 20 does not enter an authorized code, then the system hangs up, or optionally, sends the caller 20 to the subscriber's voice mail box that can reside, for example, in a remote voice messaging system 90. The caller 20 can be prompted multiple times for a correct access code before the system hangs up or sends the call to an alternate destination, such as the voice messaging system 90. It should be noted that during the period when the DND subscriber feature is activated, outgoing calls will be unaffected.

More particularly, the SPA 35 compares the collected digits to the access code(s) stored in the database 40 that preferably resides within the SCP 50. If the incoming caller 20 entered authorized correct do not disturb override digits for the subscriber 80, then at step 150, the SPA 35 passes control of the call to the terminating central office 70, which rings the subscriber's telephone 80. If the entered digits are incorrect, or if none are entered after a predetermined time, then the call is terminated at step 160.
