Abstract:
A method for managing a telecommunications network, said telecommunications network comprising several network elements to be managed by the system,said system comprising a management centre having at least one workstation accomplishing a man-machine interface and allowing a manager to control the system, and the system being capable of providing the manager with information on the network, said at least one workstation being connected to a database including information about the managed network, said information being in the form of objects that relate to the network elements to be managed and in the form of references between the different objects, said references indicating the dependencies between the objects, whereby said management centre is connected to said network elements by data communication links such that the manager can initiate an operation on a managed item of the network, in which method when the information content of an object is changed by an operation, (a) said object and all the objects depending on it are first locked to prevent another operation from changing the information content of said objects at the same time, (b) after said change has been completed a dependency checking is performed to find all dependent objects that can be unlocked, characterized in that an additional (auxiliary) data structure is formed from lockable objects, said data structure comprising object groups formed in such a way that the relationships between the objects within a single group can be cyclic and the relationships between the groups are all acyclic, each group having a count associated with it, said count corresponding to the number of references made to the group from outside, when a source object has created a new reference to a target object, the number of groups and said count are updated so that the relationships between the groups are still all acyclic, and objects within a group are unlocked when said count has a predetermined value.
