Communication between an application and a network element
First Claim
1. A management information base for a network element, said management information base being a database comprising managed objects describing variables and parameters accessible by a network management system to control and monitor said network element, wherein the management information base further comprising additional objects describing triggers and handles supported by said network element, said triggers being notifications containing information to be sent by said network element to an application upon occurrence of predefined events and said handles being commands to be sent by an application requesting execution of predefined actions at said network element.

Abstract
Network elements (NE) of a telecommunications network and an application platform (SP), which provides value-added services on top of the network, communicate with each other by means of triggers (T) and handles (H). Triggers (T) are notifications containing information to be sent by a network element to the application platform (SL) upon occurrence of predefined events and handles (H) are commands to be sent by the application platform (SL) requesting execution of predefined actions at said network element (NE). A network element (NE) includes a management information base (MIB) containing managed objects, which describe variables and parameters accessible by a network management system (NMS) to control and monitor the network element (NE). In order to allow systematic interrogation of the triggers and handles interface of a network element (NE), its management information base (MIB) stores additional managed objects which describe the triggers (T) and handles (H) supported by said network element (NE). A software module (NID), which is part of the application platform actively interrogates the network element (NE) to find out which triggers (T) and handles (H) the network element (NE) supports. The module sends requests to the network element and stores in a data model (THB) information on the interface received back from the network element (NE).

7. An application comprising a software module adapted to interrogate an interface of a network element to find out which triggers and handles the network element supports by sending requests to the network element and storing in a data model information on the interface received back from the network element, said triggers being notifications containing information to be sent by said network element to an application upon occurrence of predefined events and said handles being commands to be sent by the application requesting execution of predefined actions at said network element.
-
8. A method of interrogating a network element by an application to find out which triggers and handles the network element supports, said triggers being notifications containing information to be sent by said network element to an application upon occurrence of predefined events and said handles being commands to be sent by an application requesting execution of predefined actions at said network element, said method comprising the steps of
sending at least one request to the network element and storing in a data model information on the interface received back from the network element.
