Abstract

A system and method has been provided for the intuitive management of communication networks including a large number of network elements diffused across large geographical areas. The network management system permits the system operator to identify system problems while monitoring the top-level map of the communications network. The organization of network displays permits an operator to “zoom” from the higher levels of network abstraction, depicting a large number of elements across a large geographic area, to local geographical areas where specific problems associated with individual elements can be identified.

Claims

1. A method of managing network elements in a communications network comprising:

establishing a hierarchy of geographical areas in the communication network, where an area at a higher level of the hierarchy includes a plurality of areas at a lower level of the hierarchy;

storing geographical locations of network elements in a database;

representing each network element in a geographical area at a first level in the geographical hierarchy on a graphical user interface; and

summarizing the representation of network elements at a second level in the geographical hierarchy, higher than the first level of the geographical hierarchy;

wherein the communications network comprises a fixed wireless service (FWS) including base stations and remote units, and in which representing each network element in a geographical area at a first level in the geographical hierarchy includes representing geographical positions of network base stations and remote units.

2. The method of claim 1 in which the establishment of the hierarchy of geographical areas includes establishing n levels of geographical areas in the network, where each nth level geographical area includes a plurality of (n−

1)th level geographical areas, and in which summarizing the representation of network elements includes summarizing the representation of network elements at (n−

1) levels of geographical areas.

3. The method of claim 1 wherein the management of the communication network includes monitoring a condition of the network elements, in which the representation of network elements in the geographical area includes representing the condition of the network elements, and in which summarizing the representation of network elements at the second level in the geographical hierarchy includes triggering an alarm at the second level in response to a condition of a particular network element represented at the first level.

4. The method of claim 3 wherein the communication network is managed in real-time, and further comprising, following the representing of each network element in the geographical area:

updating the condition of one or more network elements represented in the first level of the geographical hierarchy; and

wherein summarizing the representation of network elements at the higher level in the geographical hierarchy includes triggering the alarm at the second hierarchical level in response to changes in the condition of network elements.

5. The method of claim 1 in which representing each network element in a geographical area at a first level in the geographical hierarchy includes representing at least one network element as a first icon on a map of geographical areas on the first level of the geographical hierarchy.

6. The method of claim 1 in which representing each network element in a geographical area at a first level in the geographical hierarchy includes representing a condition of at least one network element with a first icon that varies with respect to the status of the network element.

7. The method of claim 1 in which summarizing the representation of network elements at the second level in the geographical hierarchy includes representing a status of a plurality of the network elements as an icon on a map of geographical areas on the second level of the geographical hierarchy.

8. The method of claim 7 further comprising, preceding the summarizing the representation of network elements at the higher level in the geographical hierarchy:

establishing a set of rules defining the meaning of the icon.

9. The method of claim 7 in which summarizing the representation of network elements at the second level in the geographical hierarchy includes coloration of the icon.

10. The method of claim 1 in which summarizing the representation of network elements at the level in the geographical hierarchy includes summarizing a status of a plurality of the network elements with textual annotation.

11. The method of claim 1 wherein management of the network includes installation of network elements into the communications network, and in which representing each network element in a geographical area at a first level in the geographical hierarchy includes entering a latitude and a longitude of the network element upon installation into the network.

12. The method of claim 8 wherein network management is supervised, and further comprising:

creating supervisor identities; and

in which the establishment of rule-sets includes establishing a set of rules for each supervisor identity.

13. The method of claim 8 in which the establishment of rule-sets includes defining a set of rules responsive to conditions selected from a group consisting of power source status, software corruption, hardware failure, environmental factors, and intrusion into the network elements.

14. A method of determining the failure of a network element in a communications network comprising:

representing the communications network as a hierarchy of geographical areas on a graphical user interface, where an area at a higher level of the hierarchy of geographical areas includes a plurality of areas at a lower level of the hierarchy of geographical areas;

storing geographical locations of network elements in a database;

detecting a failure of one or more network elements;

sending an alarm to the higher level in the geographical hierarchy summarizing the failure of the one or more network elements; and

in response to the alarm, identifying and locating failed network elements at a lower level of the geographical hierarchy;

wherein the communications network comprises a fixed wireless service (FWS) including base stations and remote units, and in which representing each network element in a geographical area at a lower level in the geographical hierarchy includes representing geographical positions of network base stations and remote units.

15. The method of claim 14 in which representing the communications network as a hierarchy of geographical areas includes representing the communications network as a hierarchical arrangement of geographical maps where a map at the higher level of the hierarchy of geographical areas includes a plurality of maps from the lower level of the hierarchy of geographical areas.

16. The method of claim 14 in which the sending of the alarm to the higher level in the geographical hierarchy summarizing network element failures includes defining an alarm trigger that is responsive to the network element failures.

17. A method for determining the failure of a network element in a communications network comprising:

storing geographical locations of network elements in a database;

monitoring a geographical map on a graphical user interface which summarizes the status of a plurality of network elements in the communications network;

on a map display, receiving an alarm representing the failure of network elements; and

in response to the alarm, narrowing the scale of the map to geographically locate failed network elements;

wherein the communications network comprises a fixed wireless service (FWS) including base stations and remote units, and in which representing each network element in a geographical area includes representing geographical positions of network base stations and remote units.

18. A system for presenting a communications network comprising:
