BACKGROUND OF THE INVENTION 
   1. Statement of the Technical Field 
   The present invention relates to the field of call processing systems, and more particularly to processing menu changes in a telephone prompting system. 
   2. Description of the Related Art 
   Telephone prompting systems are increasing employed to provide an interface to voicemail systems and to provide an interface for interactive voice response systems (IVR), such as airline reservations, bank customer account lines, and other institutional lines such those of government, utilities, credit card companies and the like. Many systems, such as those used for banking or stock trading, may be frequently accessed by individual users, often several times a day. In such systems, users are presented with hierarchical levels of prompts that the customer can respond to by depressing buttons on the telephone keypad or through spoken words. The resulting dual tone multifrequency (DTMF) signals or audio are received by the prompting system and used to access a different level in the hierarchy or to access a specified function. 
   Prompting system technologies do not require human interaction over the telephone as the user&#39;s interaction with the database is predetermined by what the prompting system will permit the user to access. For example, banks and credit card companies use prompting systems so that their customers can receive up-to-date account information instantly and easily without having to speak directly to a person. Prompting system technology, such as that found in IVR systems also can be used to gather information, as in the case of telephone surveys in which the user is prompted to answer questions by pushing the numbers on a touch-tone telephone. 
   Sometimes, the menu structures of a telephone prompting system must be changed due to changing levels of service such as when a new service option has been added or when existing service options have been removed. Other circumstances can include the re-organization of a menu resulting from caller complaints, business rule changes or priorities, usability testing, and the like. When menu structure changes are made, it is important to inform the calling parties of such menu changes in order to minimize navigational errors, as well as erroneous transfers to unwanted agents. This can be helpful when a calling party attempts to “key ahead” to reach a known destination or menu in a prompting system but unwittingly ends up in a menu or accessing a service that is unwanted. However, after a while, repeated messages or announcements of menu changes may frustrate and annoy certain calling parties who are frequent users of the prompting system. 
   SUMMARY OF THE INVENTION 
   The present invention addresses the deficiencies of the art in respect to telephone prompting systems and provides a non-obvious method, system and apparatus for dynamically alerting calling parties of menu structure changes in a telephone prompting system. In a telephone prompting system, a menu structure change alert method can include determining whether a menu structure change has occurred for the telephone prompting system in response to the receipt of an incoming call from a calling party. Subsequently, the calling party can be selectively alerted of the menu structure change. In this regard, an alert message can be played to the calling party. 
   In a particular aspect of the invention, the step of selectively alerting the calling party can include identifying the calling party and retrieving a set of call statistics for the identified calling party. Subsequently, an alert can be provided to the calling party only if permitted by the call statistics. Otherwise, the alert can be withheld if an alert is not permitted by the call statistics. 
   In another aspect of the present invention, a call processing system can include a telephone prompting system having a menu structure. The system further can include call statistics storage configured to store call statistics for callers. Finally, the system yet further can include dynamic alerting logic configured for coupling to the telephone prompting system and the call statistics storage in order to selectively alert callers of changes to the menu structure based upon call statistics for the callers stored in the call statistics storage. 
   Additional aspects of the invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. The aspects of the invention will be realized and attained by means of the elements and combinations particularly pointed out in the appended claims. It is to be understood that both the foregoing general description and the following description are exemplary and explanatory only and are not restrictive of the invention, as claimed. 

   
     BRIEF DESCRIPTION OF THE DRAWINGS 
     The accompanying drawings, which are incorporated in and constitute part of this specification, illustrate embodiments of the invention and together with the description, serve to explain the principles of the invention. The embodiments illustrated herein are presently preferred, it being understood, however, that the invention is not limited to the precise arrangements and instrumentalities shown, wherein: 
       FIG. 1  is a schematic illustration of a system, method and apparatus for dynamically alerting calling parties of menu structure changes in a call processing system; and, 
       FIG. 2  is a flow chart illustrating a process for dynamically alerting calling parties of menu structure changes in the call processing system of  FIG. 1 . 
   

   DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS 
   The present invention is a method, system and apparatus for dynamically alerting calling parties of changes to menu structures in call processing systems. In accordance with the present invention, a dynamic alerting process can detect when changes are made to the menu structure of a call processing system. Responsive to detecting a change to the menu structure, a message can be presented telephonically in order to alert the calling party of the menu changes. Additionally, it automatically can be determined when to stop the presentation of the menu change message so as to not irritate the caller with repetitive information. 
   In operation, a query can be received in the call processing system and processed by dynamic alerting logic. The dynamic alerting logic can access call statistics for the calling party in order to determine whether a menu change message or alert can be presented to the calling party. Consequently, the dynamic alerting process provides a message to alert a calling party of menu changes while restricting the alerting feature based upon pre-determined criteria. 
   In further illustration of the foregoing inventive arrangements,  FIG. 1  is a schematic illustration of a system, method and apparatus for dynamically alerting calling parties of changes to menu structures in call processing systems. The call processing system  130  can be configured for communicative linkage to one or more calling parties  110  over the communication network  120 . In this regard, the communications network can be a PSTN, a data communications network configured to carry telephonic data, or any combination thereof. The call processing system  130  can include a telephone prompting sub-system  160  programmed to prompt calling parties  110  with information based upon a menu structure  170 . Importantly, dynamic alerting logic  140  can be coupled to the telephone prompting sub-system  160  as well as data storage of caller statistics  150 . 
   In accordance with the present invention, the dynamic alerting logic  140  can determine for an incoming call from a caller  10  whether or not the underlying menu structure  170  for the call processing system  130  has changed. If so, the dynamic alerting logic  140  can access caller statistics  150  to determine whether or not it is permissible to issue an alert to the caller  110  that the menu structure  170  has changed. If permitted, an alert can be issued to the caller  110 . Otherwise, no alert can be issued. 
   In more particular illustration of the process of the invention,  FIG. 2  is a flow chart illustrating a method for processing calls based upon the dynamic alerting process in the system of  FIG. 1 . Beginning in block  205 , a call is received by the system. The call can be received telephonically over a telephone network from an external or internal telephone calling party, or over an external or internal data communications network. 
   In further explanation,  FIG. 2  is a flow chart illustrating a process for alerting a calling party when the menu is updated or changed. Beginning in decision block  210 , the system determines if there have been any changes to the system menu. If there are no menu changes, the call can continue as normal as indicated in block  215 . Otherwise, if there is a menu change, the system will ascertain the identity of the calling party and whether the calling party has previously accessed the system in decision block  220 . If the calling party is identified, then in block  225  the “call statistics” for this specific calling party are retrieved from the storage and updated. The “call statistics” can include various calling party information such as the ID or PIN number for the calling part, the number of times the party has heard a particular alert message, and the like. If the caller does not have an identity stored in the system, a general set of call statistics can be used for this particular call as shown in block  230 . Naturally, going forward, a specific identity for this calling party can be generated and the appropriate call statistics assigned and updated. 
   The call statistics of blocks  225  or  230  are then passed to decision block  235 . In decision block  235 , the call statistics are evaluated and it can be determined whether the alert message should be played or not. As mentioned previously, various criteria may be used to determine when an alert message should no longer been provided to a calling party. A system administer can specify which call statistics (e.g., elapsed time, number of calls, some combination of these, or the like) are used to make the play or no play alert message decision. If the message should be played, the process will continue through block  245 . If not, the process can continue to block  240 . In either event, the process will continue through to block  215  where the call can be continued in a normal manner. 
   The present invention can be realized in hardware, software, or a combination of hardware and software. An implementation of the method and system of the present invention can be realized in a centralized fashion in one computer system, or in a distributed fashion where different elements are spread across several interconnected computer systems. Any kind of computer system, or other apparatus adapted for carrying out the methods described herein, is suited to perform the functions described herein. 
   A typical combination of hardware and software could be a general-purpose computer system with a computer program that, when being loaded and executed, controls the computer system such that it carries out the methods described herein. The present invention can also be embedded in a computer program product, which comprises all the features enabling the implementation of the methods described herein, and which, when loaded in a computer system is able to carry out these methods. 
   Computer program or application in the present context means any expression, in any language, code or notation, of a set of instructions intended to cause a system having an information processing capability to perform a particular function either directly or after either or both of the following a) conversion to another language, code or notation; b) reproduction in a different material form. Significantly, this invention can be embodied in other specific forms without departing from the spirit or essential attributes thereof, and accordingly, reference should be had to the following claims, rather than to the foregoing specification, as indicating the scope of the invention.
