Method for describing problems in a telecommunications network
A method for describing problems in a telecommunications network is provided, wherein the alarms for a network service displayed on an operator's console are presented in the order of the path comprising the service and associated with respective network elements, followed by a description of a recommended corrective procedure for the alarms.
1. A method implemented by a network management hardware server of a network for describing a problem in the network, the network comprising a plurality of network entities, the method comprising:
defining a service as a channel, from an originating network entity to a destination network entity, modulated by a dither tone specific to said channel, said originating network entity and said destination network entity belonging to said plurality of network entities, said service being carried by a path in the network;
selecting a subset of alarms associated with said service, the subset of alarms being selected from a list of alarms in the network;
grouping alarms in the subset of alarms associated with said service in a number of groups of alarms, each group of alarms being associated with said service and with a respective network entity from among said plurality of network entities;
ordering the groups of alarms according to a sequence in which they appear in a traversal of the path of the service in the network; and
transforming each alarm in each group of alarms into a problem description for the service.
2. A method as described in claim 1 , further comprising the step of providing a corrective procedure in response to at least one alarm in said subset of alarms.
3. A method as described in claim 1 , wherein said grouping further associates each group of alarms with a type of said network entity, where a type of said network entity is one of a node, a slot, a card and a port.
4. A method as described in claim 1 , wherein the step of grouping further comprises a step of associating at least one alarm in the subset of alarms with at least two network entities from among said plurality of network entities.
5. A method as described in claim 1 , wherein the description is a verbal description.
6. A method as described in claim 1 , wherein the description is a text description.
7. A method as described in claim 1 , wherein the description is a pictorial description.
8. A method implemented by a network management hardware server of a network for describing a problem in the network, the network comprising a plurality of network entities, the method comprising:
defining a service as a channel, having a unique identifier, connecting an originating network entity to a destination network entity, wherein said originating network entity and said destination network entity belong to said plurality of network entities, and wherein said service is carried by a path in the network;
selecting a subset of alarms associated with said service, the subset of alarms being selected from a list of alarms in the network;
grouping alarms in the subset of alarms associated with said service in a number of groups of alarms, each group of alarms being associated with said service and with a respective network entity from among said plurality of network entities;
ordering the groups of alarms according to a sequence in which they appear in a traversal of the path of the service in the network; and
transforming each alarm in each group of alarms into a problem description for the service;
wherein the step of transforming each alarm further comprises the step of forming at least one template including text substitution markers.
9. A method as described in claim 8 , wherein the text substitution markers correspond to specific network entities from among said plurality of network entities.
10. A method as described in claim 8 wherein said path is a two-way path and the step of ordering the groups of alarms comprises ordering the groups of alarms in a direction of the path from a beginning of the path to an end of the path.
11. A method as described in claim 8 wherein said path is a two-way path and the step of ordering the groups of alarms comprises ordering the groups of alarms in a direction of the path from an end of the path to a beginning of the path.
12. A method implemented by a network management hardware server of a network for describing a problem in the network, the network comprising a plurality of network entities, the method comprising:
defining a service as a channel, from an originating network entity to a destination network entity, modulated by a dither tone specific to said channel, said originating network entity and destination network entity belonging to said plurality of network entities, said service being carried by a path in the network;
selecting a subset of alarms associated with said service, the subset of alarms being selected from a list of alarms in the network;
grouping the subset of alarms associated with said service in a number of groups of alarms, each group of alarms being associated with said service and with a respective network entity from among said plurality of network entities;
ordering the groups of alarms according to a sequence in which they appear in a traversal of the path of the service in the network; and
transforming each alarm in each group of alarms into a problem description for the service;
wherein said problem triggers at least one of:
a missing channel identification alarm;
an unexpected dither tone alarm;
a loss of signal alarm; and
a channel power out of range alarm.
