Abstract

A system for creating, transferring, and monitoring services in a telecommunication system includes a service creation and management application and a service execution application. Services are created as call processing records, each call processing record comprises call processing nodes, branches and call variables. An interface specification is provided which permits the creation and management application to communicate with the execution application at a high level. Call processing records, data, and management information to be exchanged between the creation and management application and the execution application are encoded in accordance with the interface specification to permit the effective and efficient communication between the two applications and to permit the system to activate, monitor, trace, audit, and manage telecommunication services.

Claims

1. A method for controlling a telephone switching network including:

a management processor having a graphics terminal for creating a graphical representation of a telephone service which is then stored in binary form as a call processing record, a control processor having a memory, a plurality of telephones each having a corresponding telephone number, and a switching system coupled to the plurality of telephones, the method comprising the steps, executed by the management processor of;

retrieving said call processing record;

translating said call processing record from binary form into data structure form;

encoding, in accordance with an interface specification, each data structure form of a call processing record into a machine independent data transfer syntax form;

sending the machine independent data transfer syntax form of the call processing record to the control processor;

wherein the method further comprises the steps, executed by the control processor, of;

receiving said machine independent data transfer syntax form of the call processing record;

decoding, in accordance with the interface specification, each of said machine independent data transfer syntax form of the call processing record received in the receiving step to generate a plurality of service procedures;

storing the plurality of service procedures in the memory;

detecting a telephone call;

selecting one of the plurality of service procedures stored in the memory according to a telephone number corresponding to the telephone call; and

executing the selected service procedure to control the switching network.

2. The method of claim 1, wherein the decoding step includes the substeps of:

generating a service procedure including

a logic part having a plurality of instructions; and

a data storage part corresponding to the logic part, and wherein the executing step includes the substeps of reading an instruction from the logic part; and

interpreting the instruction read in the reading step and writing data into the data storage part.

3. The method of claim 1, wherein the decoding step includes the substeps of:

generating a service procedure including

a logic part having a plurality of instructions, each instruction having a respective instruction identifier, one of the instructions containing the instruction indentifier of a subsequent instruction; and

a data storage part corresponding to the logic part, and

wherein the executing step includes the substeps of reading an instruction from the logic part; and

interpreting the instruction read in the reading step and writing data into the data storage part.

4. The method of claim 1, wherein the decoding step includes the substeps of:

generating a service procedure including

a plurality of logic parts; and

a plurality of data storage parts, each data storage part corresponding to a respective logic part.

5. The method of claim 4, wherein the decoding step further includes the substep of:

generating the service procedure to include a common data part corresponding to each of the plurality of logic parts.

6. The method of claim 1, wherein the sending step includes the substep of:

embedding said machine independent data transfer syntax form of said call processing procedure in a message having a certain format; and

sending the message.

7. A system for controlling a telephone network having a plurality of telephones, each telephone capable of originating a phone call, the system comprising:
