FIELD OF THE INVENTION
This invention relates to the field of telecommunications systems. More particularly, this invention relates to the field of voice messaging platforms within telecommunications systems employing intelligent peripherals.
BACKGROUND OF THE INVENTION
In the past, services which were integrated with a voice messaging platform needed to be implemented on the voice messaging platform. For example, these services include billing the call to a remote location, switching functionality such as placing additional calls or conferencing calls together, call screening, querying subscriber information such as access level and functionality, translating numbering plans for number portability, querying real time subscriber status for call completion, and the like. The typical voice messaging platform would need to be individually upgraded to accommodate these above mentioned services. To be properly upgraded to implement these new services, the voice messaging platform usually required additional network interfaces, additional network ports, additional switching functionality, and additional subscriber data.
Currently, subscribers to voice messaging systems have become more sophisticated in their voice messaging use and require improved services and additional features. As the demands for more sophisticated services grow, service providers will continue to implement new additional services. However, to implement new services throughout a given service area, prior art systems require substantial modifications to every voice messaging platform within this given service area. For example, to add the feature of call screening within a given area, every voice messaging platform within this given area needs to be modified by adding network interfaces, utilizing additional network ports, providing switching functionality, adding additional subscriber data, and the like. Modifying each voice messaging platform to implement each new feature is a time-consuming task which increases the costs of providing new services and delays introduction of additional functionality related to these new services.
What is needed a voice messaging platform that is capable of adding new services without physically modifying the voice messaging platform. What is needed is a voice messaging platform which functions as an intelligent peripheral within an intelligent network. What is further needed is a voice messaging platform which is capable of utilizing resources of other intelligent peripherals.
SUMMARY OF THE INVENTION
The present invention is a voice messaging platform that utilizes resources from remote intelligent peripherals within the network system. The voice messaging platform preferably includes a voice mail module, an internal controller, and an internal storage device. Preferably, the voice mail module allows the voice messaging platform to provide a full feature voice mail system for the users wherein the voice mail module is configured to store incoming messages, play stored messages, play outgoing messages, place outgoing calls, and the like. The internal controller preferably directs the voice messaging platform to detect different types of resources available to the voice messaging platform from the remote intelligent peripherals. Further, the internal controller also directs the voice messaging platform to find addresses corresponding to each of the remote intelligent peripherals within the network system. Preferably, the internal storage device stores the type of resource available from the remote intelligent peripherals and their respective addresses.
By locating and utilizing resources from remote intelligent peripherals, the voice messaging platform is capable of incorporating additional features by merely introducing remote intelligent peripherals that provide functionality for these additional features. The voice messaging platform does not need to be modified to introduce additional features for users. Preferably, additional features are capable of being added to a service area without changing or modifying every voice messaging platform within this service area.

FIG. 2 illustrates a timing diagram for describing the operation of the preferred embodiment of the present invention. For the sake of simplicity and clarity, common elements shown in both FIGS. 1 and 2 also share common reference numerals. For example, the SCP 130, the voice messaging platform 110, and the intelligent peripheral 140 are common in both FIGS. 1 and 2. To prevent obscuring the preferred embodiment of the present invention, selected details are omitted in FIG. 2 such as control links between the SCP 130, the voice messaging platform 110, and the intelligent peripheral 140 which are specifically shown in FIG. 1 and described above.
In this timing diagram, the voice messaging platform 110 in conjunction with the internal controller 120 and the internal storage device 125 are described in context with the overall functionality of the Intelligent Network 100 (FIG. 1). As shown in FIG. 2, this timing diagram illustrates interaction between the SCP 130, the voice messaging platform 110, the internal controller 120, the internal storage device 125, and the intelligent peripheral 140.
