Abstract

A re-engineering method for standardizing data processing in a communication network while maintaining user services is disclosed. Data channels, between communicating network data processing components (hereinafter denoted operational components), are made unnecessary by systematically providing bypass data paths. The data on each bypass, transparent to its terminating operational components, is routed through a network manager communicating in a standardized protocol. The manager thereby provides centralized control of data communications and provides standardized object oriented data representations and protocols. For a selected operational component having a bypass for each data channel, the functionality of the selected operational component may be incrementally and transparently assumed by new operational components communicating with the manager. Thus, a selected operational component using nonstandard data representations and communication protocols can be isolated from other network components and deactivated while maintaining user services. The present invention is particularly useful in re-engineering telephony networks having noncentralized and nonstandardized communications between various combinations of network elements and operational support systems.

Claims

1. An apparatus for accessing network management information communicated between first and second operational components of a telecommunications network, comprising:

first translator means for translating network management information between first and second different network management protocols, wherein said first protocol is used by said first and second operational components for communicating first network management information, via a network management information path including said first translator means;

second translator means for translating network management information between said second and said first network management protocols, wherein

(A1) said network management information path includes said second translator means;

(A2) said first translator means translates said first network management information between said first protocol, for communicating with said first operational component, and said second protocol, for communicating with said second translator means; and

(A3) said second translator means translates said first network management information between said second protocol, for communicating with said first translator means, and said first protocol, for communicating with said second operational component;

accessing means for accessing said first network management information output in said second protocol from at least one of said first and second translator means, wherein said accessing means comprises a network information manager configured for capturing and controlling access to said first network management information, where said network manager comprises an object oriented model for modeling a performance of said telecommunications network.

2. An apparatus as claimed in claim 1, wherein said first protocol is less widely applicable for use in communicating network management information between operational components of said telecommunications network than said second protocol.

3. An apparatus as claimed in claim 1, wherein said second protocol includes object oriented messages.

4. An apparatus as claimed in claim 1, wherein said first and second translator means are configurable according to first and second translation mapping data supplied, respectively, to said first and second translator means.

5. An apparatus as claimed in claim 4, wherein said first and second translation mapping data provide different specifications for performing a different translation.

6. An apparatus as claimed in claim 4, wherein said first and second translators are identical.

7. An apparatus as claimed in claim 4, wherein said first and second translation mapping data is derived substantially from one or more generic operations interface specifications for telecommunications network elements.

8. An apparatus as claimed in claim 1, wherein said accessing means includes a data connection for tapping said network management information path between said first and second translator means.

9. An apparatus as claimed in claim 1, wherein said network information manager stores at least a portion of said first network management information in a network management information base for access by another operational component of said telecommunications network.

10. An apparatus as claimed in claim 9, wherein said network management information base includes information related to at least one of:

circuit switch network traffic, circuit switch provisioning, billing for said telecommunications network services, network switch alarm and surveillance, and network switch control.

11. An apparatus as claimed in claim 9, wherein said network management information base includes information related to an SS7 telecommunications network.

12. An apparatus as claimed in claim 9, wherein said network management information base includes information related to transport network elements.

13. An apparatus as claimed in claim 1, wherein said network information manager provides objects from a class hierarchy for said telecommunications network to operational components of said telecommunications network.

14. An apparatus as claimed in claim 1, wherein said network information manager is a server in a client-server paradigm wherein a client is an operational component of said telecommunications network.

15. An apparatus as claimed in claim 1, wherein said first and second translator means include first and second polling means, respectively, for polling for network management information on said network management information path, wherein said second operational component requests said first network management information from said first operational component by polling said second translator means, said second translator means using said second polling means polls said first translator means, said first translator means using said first polling means polls said first operational component for said first network management information.

16. An apparatus as claimed in claim 1, wherein said first and second operational components are each one of:

a network element, an operational support system and a data base management system.
