LTE and Enhanced UTRAN introduced significant improvements in the amount of bandwidth provided for wireless transmission using cellular technology, truly paving the way for mobile broadband. In order to provide support for the type of applications and traffic that these access networks would enable, it was necessary to prepare the core network. In conjunction with the evolution of the access networks provided with LTE, the convergence of technologies at the IMS level meant that it was now also possible to provide a common packet core with appropriate policy, security, charging, and mobility. This provides end-users with ubiquitous access to network services across ...
