Abstract

The procedure and system of the invention are used to implement a technical application from which all uncontrolled internal interdependencies have been eliminated. The functional assemblies contained in the application are normalized so that the input data of each functional assembly unambiguously and alone determines the output data produced by the assembly. Further, according to the invention, the elements contained in the functional assemblies are normalized so that the input data of the elements unambiguously and alone determines the output data. There may be one or more elements or functional assemblies. Further, a functional assembly may form other functional assemblies. In an embodiment of the invention, the application implemented is a part of a telephone exchange software application in which the functional assemblies and elements are of an algorithmically processing type.

Claims

A method of implementing an application and eliminating uncontrolled internal interdependencies within the application, with the application comprising a number of functional entities, each entity comprising one or more elements, and with the application producing application output data from input data such that element output data produced by the elements determines entity output data produced by the functional entities and the entity output data determines the application output data, wherein there are interdependencies formed between the elements, between the functional entities, or between the elements and the functional entities, said method comprising:

normalizing an element such that uncontrolled internal interdependencies within said element are eliminated, and such that the input data supplied to said element solely determines element output data produced by said element.

2. A method as recited in claim 1, wherein at least one normalized element forms a functional entity, and wherein output data of the functional entity is determined by the at least one normalized element.

forming at least one functional entity from at least one normalized element; and

normalizing the at least one functional entity.

4. A method as recited in claim 1, wherein the normalized element comprises a normalized functional entity.

5. A method as recited in claim 1, wherein the normalized element forms at least one normalized functional entity, and wherein the output data of the application is solely determined by the normalized functional entity.

6. A method as recited in claim 1, wherein said normalized element forms at least one normalized functional entity, and wherein the at least one normalized functional entity is formed by joining at least two elements of said plurality of elements in parallel, as a union.

7. A method as recited in claim 1, wherein said normalized element forms at least one normalized functional entity, and wherein the at least one normalized functional entity is formed by selecting at least one item of element output data.

8. A method as recited in claim 1, wherein said normalized element forms at least one normalized functional entity, and wherein the at least one normalized functional entity is formed by specifying element output data based upon input data.

9. A method as recited in claim 1, said method further comprising the steps of:

executing a plurality of normalized elements in cascade, wherein the output data of the element affects input data of another element of the plurality of normalized elements.

10. A method as recited in claim 1, further comprising the steps of:

conditionally executing normalized elements, wherein when a second normalized element produces predetermined output data, input data for a first normalized element is determined, and wherein when the second normalized element does not produce the predetermined output data, no input data is determined for the first normalized element.

11. A method as recited in claim 1, further comprising the steps of:

repeatedly executing the normalized element, with a number of repeated executions of a first element being determined by output data of a second element.

12. A method as recited in claim 1, wherein the application is implemented as telephone exchange software in a mobile communication system.

13. A system for implementing an application and eliminating uncontrolled internal interdependencies within the application, wherein the application comprises a number of functional entities, each entity comprising one or more elements, and wherein the application produces application output data from input data such that element output data produced by the elements determines entity output data produced by the functional entities and the entity output data determines the application output data, and wherein there are interdependencies formed between the elements, between the functional entities, or between the elements and the functional entities, said system comprising:

normalizing means for normalizing one or more elements such that uncontrolled internal interdependencies within each element are eliminated, and such that the input data supplied to each element solely determines element output data produced by said element.
