Method and communication system for handling alarms using a management network having a number of management levels
DCFirst Claim
1. A method for handling alarms in a communication system using a management network having a number of management levels, wherein alarm data for active alarms is transmitted for parallel alarm realignments between an agent on a first management level and managers on a next highest management level, said method comprising the steps of:
- transmitting from each of the managers to the agent at least one request having a request notification for transmission of alarm data; and
transmitting from the agent to a respective manager a number of notifications having the requested alarm data along with at least one item of correlation information for assigning a respective request to the notifications.

Abstract
Alarm data for active alarms is transmitted for alarm realignment between an agent on one management level and at least one manager on a next highest management level. The manager sends one or more request notifications to the agent for transmission of the alarm data, and correlation information for assigning the respective request to the notifications which are subsequently sent by the agent is received. This means that, in the management network, a number of alarm realignments can take place simultaneously between the agent and a number of managers or serially between the agent and an individual manager without observing the sequence of requested realignments.

wherein the manager transmits, in the request notification, a first item of correlation information for assigning the respective request to the notifications having the alarm data which are subsequently transmitted by the agent; - and
wherein the agent transmits to the manager a notification for starting the alarm realignment, said notification containing a second item of correlation information for the respective request and a third item of correlation information for assigning to the respectively started realignment the notifications having the alarm data which are subsequently transmitted by the agent.

-
3. The method as claimed in claim 1, wherein the agent also transmits to the manager, in the respective notifications having the alarm data, a further item of correlation information for assigning the notifications to the respectively started realignment.
-
4. The method as claimed in claim 1, further comprising the steps of:
after transmitting the notifications with the alarm data, transmitting from the agent to the manager a further respective notification for ending the alarm realignment, said further notification containing a further item of correlation information for the respective request.
-
5. The method as claimed in claim 1, further comprising the steps of:
using in the agent at least one filter function with filter criteria for the notifications produced by the agent, said notifications being controlled by an assignable manager and being routed to a manager only if the filter criteria are satisfied.
-
6. The method as claimed in claim 1, wherein at least two managers transmit a number of request notifications with an item of correlation information which can in each case be assigned to the requests.
-
7. The method as claimed in claims 6, wherein the managers are formed by different network elements in the management network.
-
8. The method as claimed in claim 6, wherein the managers are formed by various network management centers;
- and wherein the respective item of correlation information for assigning the request to the respective network management center is sent in the request notification.
-
9. The method as claimed in claim 1, wherein one manager transmits a number of request notifications with the item of correlation information, said item of correlation information being assignable in each case to the requests.
-
10. The method as claimed in claim 9, wherein the manager transmits the request notifications for different applications.
-
11. The method as claimed in claim 9, wherein the manager is formed by an operation and maintenance center having various applications;
- and wherein the respective item of correlation information for assigning the request to the respective application is transmitted in the request notification to a base station subsystem.
-
12. The method as claimed in claim 9, wherein the manager is formed by a network management center having various applications;
- and wherein the respective item of correlation information for assigning the request to the respective application is transmitted in the request notification to an operation and maintenance center.
-
13. A communication system for handling alarms using a management network which has a number of management levels, the alarm data for active alarms being transmitted for parallel alarm realignments between an agent on one management level and a number of managers on a next highest management level, the communication system comprising:
-
a number of managers each having;
a first transmitter for transmitting at least one request having a request notification for transmission of the alarm data, and a first receiver for receiving a number of notifications having the requested alarm data along with items of correlation information for assigning the respective request to notifications; and
at least one agent having;
a second transmitter for transmitting to the manager the notifications having the requested alarm data along with the items of correlation information, and a second receiver for receiving said transmissions from the manager. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21)
wherein the request notification comprises a first item of correlation information for assigning the respective request to the notifications having the alarm data which are subsequently received from the agent; - and
wherein the second transmitter in the agent is further for transmitting to the managers a notification for starting the alarm realignment, said notification containing a second item of correlation information for the respective request and a third item of correlation information for assigning to the respectively started realignment the notifications having the alarm data which are subsequently transmitted by the agent.

-
17. The communication system as claimed in claim 15, wherein the managers for transmitting the request notifications are network management centers.
-
18. The communication system as claimed in claim 13, wherein at least one of said managers is provided for sending a number of request notifications having correlation information which can in each case be assigned to the requests.
-
19. The communication system as claimed in claim 18, wherein at least one of said manager is provided for sending request notifications for different applications.
-
20. The communication system as claimed in claim 18, further comprising:
