How To Do Automation Testing For LTE Call Flow

Overview:

Long Term Evolution (LTE) is the so called 4th Generation (4G) mobile standard in the rapidly evolving mobile technologies. Its distinguishing feature is an all IP infrastructure and significantly greater air interface bandwidth to the mobile handset. It was developed as an enhancement to the existing 3G UMTS System (Universal Mobile Telecommunications System) to provide users enhanced mobile radio and internet access.

The LTE air interface is a completely new system based on orthogonal frequency-division multiple access (OFDMA) in the downlink and single-carrier frequency-division multiple access (SC-FDMA) in the uplink. The system efficiently supports multi-antenna technologies (MIMO).

Another significant feature of LTE is its high bandwidth — up to 20 MHz. The LTE can also operate in the existing 5-MHz UMTS frequency bands, or in even smaller bands, as the usable bandwidth is scalable.

However, deploying high-quality voice, video, and data services over LTE has posed significant challenges for service providers, due to backward-compatibility, inter-operability, and high quality requirements — all of which requires rigorous testing.
