Improvement of VoLTE Domain HO with Operators Vision

The 3GPP evolution for the 3G mobile system created the new base station system, called Evolved UMTS Terrestrial Radio Access Network (E-UTRAN) and a new core network, called Evolved Packet Core (EPC) as a result of two standardisation projects: Long Term Evolution (LTE) and System Architecture Evolution (SAE).

“Signalling in E-UTRAN/LTE” course focuses on signalling between EPS/LTE nodes within E-UTRAN. During the course all protocols and signalling procedures on all interfaces (i.e. Uu, X2 and S1) within E-UTRAN are presented in details. The course also describes overview of EPS architecture and system wide signalling procedures, including EPC - E-UTRAN interworking.

Qualcomm believes that the next significant performance leap will come from heterogeneous networks, or HetNets, which bring the network closer to the user through low-power nodes such as pico and femto-cells. LTE Advanced uses adaptive interference management techniques to further improve the capacity and coverage of these HetNets.

At 5th Telecoms Evangelist meet up Andy Sutton of EE gave a presentation reviewing the latest trends and developments in mobile backhaul architecture, strategy and technology.

At ’Critical Communications World’ conference, Balazs Bertenyi, the 3GPP SA Chair, recently reported on the latest status of the first 3GPP features for public safety, in particular those covering Proximity services (Direct mode) and Group call.
