[1] Development began in 1966 to keep track of the bill of materials for the Saturn V rocket of the Apollo program, and the first version on the IBM System/360 Model 65 was completed in 1967 as ICS/DL/I and officially installed in August 1968.
An evolved IP Multimedia Subsystem (IMS) developed in an access independent manner; 3GPP is a consortium with seven national or regional telecommunication standards organizations as primary members ("organizational partners") and a variety of other organizations as associate members ("market representation partners").
Having seen a little of what is IMS and the devices that act, we enter IMS specifications relating to security. From the point of view of the standardization, only exists a mechanism of authentication and access control, specified in the TS 33.203 of 3GPP (Access Security for IP-Based Services) and commonly called AKA (Authentication and Key Agreement).
The IMP is expanded to a time-based IMS to produce a networked and multi-layered schedule showing all detailed tasks required to accomplish the work effort contained in the IMP. The IMS flows directly from the IMP and supplements it with additional levels of detail——both then form the foundations to implement an Earned Value Management System.
