Method and device for defining objects allowing establishment of a device management tree for mobile communication devices

Abstract

A method for defining description objects to be included into a hierarchical structured device description framework (DDF), where the DDF is constituted by a plurality of objects being hierarchically inter-associated to each other forming a kind of tree-like structure. The hierarchical structure is obtained by using different types of objects comprising at least: fixed parent object, run-time parent object, leaf object and link object. Each description object has one directly superordinate associated object, i.e. a parent object, whereas objects of the types fixed parent object and run-time parent object are allowed to have none, one or more objects being directly associated subordinate, i.e. child objects. At least one new object is defined to be associated to a parent object. If the parent object is a fixed parent object, the at least one new object is allowed to be a fixed object, run-time object, leaf object or link object.
