MOBILITY IN TELECOMMUNICATION NETWORKS

摘要

A system for managing data used by application software having a plurality of application modules (401, 402, 403) executable on switching systems located throughout a heterogeneous telecommunications network (400). Portions of data are stored in data managers (DM) at a plurality of data storage locations distributed within the network (600) independently of the application modules (AM). Each storage location is also supported by a data manager. An application module (AM) is executed to define a parameter of the data required for the execution of the application software. The data manager (DM) supporting the application module (AM) is requested to search the data managers (DM) at the data storage locations for the required data and to identify the data manager (DM) in which the required data is stored. The required data is retrieved from the identified data manager (DM) and written from the identified data manager to the application module (AM) for use during continued execution of the application software.
