Abstract

A method of controlling a telecommunication network management is disclosed. By the method, a managing subject of a telecommunication network carries out a management sequence for management information of the telecommunication network in an agent subject. The method comprises the steps of (a) locating a cache storing the management information in the managing subject; and (b) partitioning attributes of the management information into attribute classes corresponding to demands for cache coherency. In the method, the managing subject carries out the management sequence with a higher speed by accessing the cache, and manages the cache for each attribute class efficiently.

Claims

1. A method of controlling telecommunication network management;

wherein a managing subject is provided with a management sequence to control communication related management information of a telecommunication network by controlling an agent subject, said method comprising the steps of;

providing a cache for storing said management information in said managing subject; and

classifying attributes of said management information according to attribute class, each class corresponding to its tolerance for cache coherency error determined by a requirement from a program to control the management sequence;

wherein said managing subject carries out said management sequence with a higher speed by accessing said cache, and manages a cache area for each attribute class efficiently.

2. The method as claimed in claim 1, wherein said agent subject comprises non-volatile storage means for storing information of said managing subject connected to the agent subject.

3. The method as claimed in claim 1, wherein said method further comprises the step of automatically generating initializing programs for providing a cache area for each attribute class and setting an initial value in the cache area by determining said attribute class form a definition of said management information.

4. The method as claimed in claim 1, wherein said method further comprises the step of automatically generating interface processing programs for executing a coherency protocol for each attribute class by determining said attribute class from a definition of said management information.

5. The method as claimed in claim 1, wherein said method further comprises the step of ensuring said cache coherency by using a coherency protocol corresponding to each attribute class.

6. The method as claimed in claim 1, wherein said method further comprises the step of managing said cache based on a least-recently-used algorithm.

7. The method as claimed in claim 2, wherein said method further comprises the step of restoring the management information stored in the non-volatile memory of the agent subject with the management information stored in the cache of the managing subject, after a problem occurred in the agent subject has been fixed.
