Signalling in EPC/LTE: CSFB and SMSoSGs

“Signalling in EPC/LTE” course focuses on signalling between EPS/LTE nodes within GPRS Tunnelling Protocol (GTP) based Evolved Packet Core (EPC)* network. During the course all protocols and signalling procedures on all interfaces (i.e.

VoLTE Basics: SMS

Unlike previous 3GPP wireless technologies, LTE has no Circuit Switched (CS) bearer to support voice, so carrying voice over LTE requires a migration to a Voice over IP (VoIP) solution.

LTE/EPS Technology: Core Network

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: X2 Interface

“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.

CSFB and SMSoSGs

The CS FallBack (CSFB)  in EPS enables the provisioning of voice and other CS-domain services (e.g. CS UDI video, LCS, USSD) by reuse of CS infrastructure when the UE is served by E-UTRAN. A CSFB enabled terminal, connected to E-UTRAN may use GERAN or UTRAN to connect to the CS-domain.

Validating voice over LTE end-to-end

Ericsson - Unlike previous 3GPP wireless technologies, LTE has no circuit-switched bearer to support voice, so carrying voice over LTE requires a migration to a voice over IP (VoIP) solution – commonly under the umbrella of IMS. Until this migration occurs, LTE-capable handsets need to revert to 2G or 3G for voice calls: an approach that is not ideal in the long term.

LTE-Advanced Tutorial

The next important milestone is the standardization of LTE-Advanced (LTE Rel.10 and beyond).

Next generation LTE, LTE-Advanced or LTE Rel-10 is the next step in radio access technology

Whatever the name – next generation LTE, LTE-Advanced or LTE Rel-10 – the next step in LTE evolution allows operators to introduce new technologies without putting exis

MIMO Technologies in 3GPP LTE and LTE-Advanced

Multiple input multiple output (MIMO) technologies introduced in LTE such as spatial multiplexing, transmit diversity, and beamforming are key components for providing higher peak rate at a better
